Analisis morfometrik menunjukkan hubungan berkebalikan antara jumlah dan ukuran biji pada Reutealis trisperma
type: item
description: The fitness of many angiosperm plants, including Reutealis trisperma, is affected by the size and number of fruit and seed. However, studies on the fruit and seed morpho-physiology of R. trisperma are still highly limited. This study aimed to identify the variation of locule and seed number besides the fruit and seed morphometric traits of R. trisperma. The number of locules and seeds per fruit was observed in immature, developing R. trisperma fruits. These observations were made by cross-sectioning R. trisperma that was obtained from field collections. Morphometric data collection was subsequently carried out on sampled mature fruits. The results showed that the locule and seed number of the single fruit of R. trisperma ranged from 2 to 4 and 1 to 4, respectively. Trilocular fruits were the most commonly found type. However, some of trilocular fruits were consisted of two seeds (two-seeded fruits) instead of three seeds (three seeded fruits). The proportion of two-seeded fruits was comparable to the three seeded fruits. No significant differences were found in fruit size or weight between two-seeded and three-seeded fruits. However, the seed weight, as well as the kernel weight, were heavier for two-seeded fruits compared to three-seeded fruits. Therefore, it revealed a seed size-number trade-off. These results can enrich the valuable informations related to the growth and development as well as the fitness of R. trisperma. ABSTRAK Daya reproduksi beberapa tanaman angiosperma, termasuk Reutealis trisperma, dipengaruhi oleh ukuran serta jumlah buah dan biji.

Trend perubahan cuaca ekstrem dan pengaruhnya terhadap tanaman kedelai di Kabupaten Majalengka Jawa Barat
type: item
description: Recent climate change has led to an increase in extreme weather events which pose a threat to the agricultural sector, including soybean crops that has high nutritional value and is in demand by the public. However, the impact of extreme weather on soybean production remains to be scientifically validated. Therefore, research is needed to determine extreme weather events and their effects on soybean production in Majalengka Regency. The method used in this research was quantitative descriptive by carrying out trend analysis of extreme weather such as maximum rainfall, maximum and minimum temperatures, wet spells, dry spells and maximum wind speed and Pearson correlation analysis of extreme weather and harvest area, productivity and production of soybean. The research was carried out using daily weather element data from 1990 to 2021 obtained from Indonesian Agency for Meteorological, Climatological, and Geophysics Jatiwangi Majalengka Regency. The data regarding the harvest area, productivity, and production of soybeans were obtained from the Agriculture Service and the Central Bureau of Statistics Majalengka Regency. The research results show that extreme weather in Majalengka Regency has changed with indications of an increase in minimum temperature of 0.6 ⁰C, maximum temperature of 0.12 ⁰C, wet spell for 3 days, dry spell for 1-day, maximum wind speed of 17.6 km/hour, and a decrease in maximum rainfall of 43.7 mm. However, besides the increase in minimum temperature, these extreme weather changes did not affect the decrease in soybean production, productivity, and harvest area, while maximum temperature and wet spell significantly affected the increase in soybean productivity.

Respon bibit kopi liberika bermikoriza terhadap cekaman kekeringan di media tanah gambut
type: item
description: Drought stress is one of the main limiting factors affecting the growth and nutrient uptake of Liberica coffee seedlings in peat soil media. Therefore, appropriate technologies are needed to address this issue, one of which is the application of biological agents such as mycorrhiza. This study aims to evaluate the response of mycorrhiza-inoculated Liberica coffee seedlings to drought stress in peat soil media. The experiment was conducted using a factorial Split-Plot Design with two treatment factors. The first factor (Main Plot) was drought stress, consisting of five levels: 100%, 80%, 60%, 40%, and 20% of field capacity water availability. The second factor (Sub-Plot) was different mycorrhizal treatments, consisting of four levels: no mycorrhiza inoculation, Glomus sp-1a, Glomus sp-3c, and a combination of Glomus sp-1a dan Glomus sp-3c. The results showed that mycorrhiza inoculation, particularly the combination of Glomus sp-1a and Glomus sp-3c, significantly improved the growth and nutrient uptake of Liberica coffee seedlings in peat soil under drought stress conditions. The combination of Glomus sp-1a and Glomus sp-3c provided optimal growth and nutrient uptake up to a drought stress level of 40%, while its effectiveness tended to decline at higher stress levels. These findings indicate that mycorrhizae play a crucial role in enhancing the drought tolerance of Liberica coffee seedlings in peat soil media. ABSTRAK Cekaman kekeringan merupakan salah satu faktor pembatas utama dalam pertumbuhan dan penyerapan hara bibit kopi liberika pada media tanah gambut. Oleh karena itu diperlukan suatu teknologi yang dapat mengatasi permasalahan tersebut, diantaranya melalui aplikasi agen hayati berupa mikoriza. Tujuan dari penelitian ini adalah untuk mengkaji respons bibit kopi liberika bermikoriza terhadap cekaman kekeringan di media tanah gambut. Percobaan dilakukan menggunakan Rancangan Petak Terbagi faktorial dengan dua faktor perlakuan, yaitu cekaman kekeringan yang terd…

Karinding: kearifan lokal budaya Jawa Barat sebagai pengendali hama pada tanaman padi
type: item
description: The green revolution promoted synthetic pesticide use in agriculture, but this practice negatively affects the environment and health. Karinding, a traditional musical instrument from West Java, is believed to offer an eco-friendly alternative for repelling pests in rice cultivation. This study aimed to evaluate the effectiveness of karinding as a pest control method. A non-factorial randomized block design was used with four treatments: control, manual karinding, recorded karinding, and synthetic pesticide. Each treatment involved 10 rice clumps, repeated four times, with 10-m spacing to minimize bias. Parameters observed included pest attack intensity, insect diversity, soil pH, and microorganism population. Results showed no significant difference in pest attacks between weeks 4–12, except in week 7 where synthetic pesticides had the lowest intensity (13.15%). Insect diversity was moderate across treatments, highest in the control (H’=2.083) and lowest in the pesticide treatment (H’=1.595), with no dominant species (C<0.5). The synthetic pesticide reduced overall insect populations, although some species remained. Soil pH in karinding treatments ranged from 5.7–5.8, with higher microorganism populations than in the pesticide treatment. The highest number of panicles per hill was in the control (40.72), and the lowest in the pesticide treatment (22.27), while panicle length and dry grain weight were not significantly different. Although less effective than synthetic pesticides in suppressing pests, karinding helps preserve insect diversity and soil health, making it a promising environmentally friendly pest control alternative. ABSTRAK Revolusi hijau mendorong penggunaan pestisida sintetik dalam pertanian, namun penggunaannya berdampak negatif bagi lingkungan dan kesehatan. Karinding, alat musik tradisional Jawa Barat, diyakini sebagai alternatif ramah lingkungan untuk mengusir hama pada tanaman padi. Penelitian ini bertujuan menguji efektivitas alat musik karindi…

Population of P-solubilizer bacteria, available P, P Uptake and chili yield affected by bioameliorants and nutrient
type: item
description: The consumption of red chili (Capsicum annum L.) increased annually, requiring higher productivity. However, this is not supported by optimal soil fertility which has a low nutrient content. This research aimed to examine the interaction between bioameliorant dose (B) and nutrient solution application interval (F) on phosphate solubilizing bacteria (PSB), available P, P uptake, fruit weight per plant, and fruit weight per fruit. The research was conducted using a Factorial Randomized Block Design with two factors and three replications (bioamelioran dosage: 0, 3, 6 t ha-1) and nutrient solution application interval: every one, three, and five days. The results showed an interaction effect on fruit weight with the best treatment being a bioameliorant dose of 3 t ha-1 and a nutrient solution interval once a day. The bioameliorant increased available P and the nutrient solution interval had influenced on soil available P and fruit weight per plant. Application of a bioameliorant dose of 3 t ha-1 and nutrient solution interval once a day produced the highest yield of chili. ABSTRAK Konsumsi cabai merah (Capsicum annum L.) meningkat setiap tahunnya, sehingga membutuhkan produktivitas yang lebih tinggi. Namun, hal ini tidak didukung oleh kesuburan tanah yang optimal serta memiliki kandungan nutrisi yang rendah. Penelitian ini bertujuan untuk mengetahui interaksi antara dosis bioamelioran (B) dan interval pemberian larutan hara (F) terhadap bakteri pelarut fosfat (BPF), P-tersedia, serapan P, bobot buah per tanaman, dan bobot buah per buah.

Hasil padi (Oryza sativa l.) pada lahan sub-optimal akibat pemberian pupuk berbasis sensor
type: item
description: Rice (Oryza sativa L.) is a key commodity in maintaining national food security. However, its production increase is still constrained by limited land availability and low fertilization efficiency, particularly in sub-optimal lands with poor soil fertility. This study aimed to evaluate the effectiveness of sensor-based fertilization on the yield of two rice varieties, IPB 9G and Gogo rice, under sub-optimal conditions. The research was conducted in Kembang Kerang Daya Village, East Lombok, using a split-plot randomized block design with two factors: fertilizer dose (6 levels, including sensor-based recommendations) as the main plot, and rice variety as the subplot, with three replications. Yield components observed included the number of grains per panicle, percentage of filled grains, 1000-grain weight, yield per plot, and estimated yields of harvested dry grain and milled dry grain. The results showed that sensor-based fertilization, combining inorganic, organic, and bio-fertilizers, produced the best performance in nearly all yield parameters, particularly in the IPB 9G variety. This system significantly increased GKG yield compared to conventional fertilization methods. The agronomic efficiency of sensor-based fertilization was 27% higher than conventional fertilization, aligning with the principles of precision agriculture. In conclusion, applying sensor-based fertilization on sub-optimal land presents a promising innovative solution to enhance rice productivity and input efficiency, especially in areas with low soil fertility. ABSTRAK Padi (Oryza sativa L.) merupakan komoditas utama dalam menjaga ketahanan pangan nasional, namun peningkatan produksinya masih terkendala keterbatasan lahan dan rendahnya efisiensi pemupukan, terutama pada lahan sub-optimal yang memiliki tingkat kesuburan rendah.

description: Sweet potato (Ipomoea batatas L.) is a nutritionally rich alternative food source with a high starch content and ranks among the world's most important food crops. As a global food commodity, the development of high-yielding cultivars requires the evaluation of promising genotypes. Among the various types, white-fleshed sweet potato (WFSP) is particularly valued due to its suitability as a raw material for flour production. The increasing industrial demand for sweet potato-based flour highlights the urgency to select high-yielding WFSP genotypes to meet market needs. This study aimed to identify WFSP genotypes with superior yield potential and high harvest index. The experiment was conducted from November 2023 to April 2024 in Rancakalong, Sumedang District, West Java, using eight WFSP genotypes and three check varieties (Rancing, Sukuh, and AC Putih). A randomized complete block design (RCBD) with three replications and 11 treatments was employed. Significant variation was observed among genotypes for traits such as number of tubers per plant, tuber weight per plant, number of marketable tubers, total tuber count, and total tuber weight. Six genotypes—Keriting Maja, MZ 154, Sorong, MBD, PR 119, and MNHR—demonstrated high yield performance, with Keriting Maja showing the highest potential at 35.09 t ha-1, making it a strong candidate for future cultivar development.

Population of vector and tungro disease incidence at dosage of nitrogen fertilizer in rice field
type: item
description: One of the biotic threats that can reduce rice yield is tungro disease. This disease is spread with green leafhopper (Nephotettix virescens) vector. The population density of leafhoppers is one of the factors contributing to the increased incidence of tungro. Excessive nitrogen used in crop cultivation, especially rice, has been known to impact the population dynamics of insect pests. This study aims to determine the population development of green leafhoppers at different nitrogen doses. The study was conducted at the Muara Experimental Field, Bogor. The experimental treatment used three rice varieties representing susceptible varieties, resistant to green leafhoppers and resistant to tungro virus (Ciherang, IR64 and Inpari 36 Lanrang) and four levels of fertilization doses (without additional urea, Urea 250 kg ha-1, 350 kg ha-1 and 500 kg ha-1). The experiment used Split Plot design with three replication. The insect population in the field was found at the beginning of the observation and the peak of insect population density occurred at 6 WAP observationsVariety has a significant effect on insect vector population density and plant growth and yield in the field. The population density of green leafhoppers was higher in the Ciherang and IR 64 varieties than in the Inpari 36 Lanrang variety. Fertilization doses had no significant effect on the population of green leafhopper insects in the field except in the nymph phase in fertilization without the addition of urea and had no effect on growth and yield except on the number of tillers. The combination of resistant varieties and fertilization without the addition of urea reduced the population density of green.

Karakteristik fisik carbon dots dan aplikasinya dengan pemupukan untuk meningkatkan produksi dan mutu benih padi
type: item
description: Carbon dots (CDs) are nano-sized carbon particles proven to enhance seed germination, plant growth, and yield. This study evaluated CDs in an integrated fertilization system combining macronutrient fertilizers (NPK) and organic matter (OM). The experiment was conducted during the 2023 dry season at the Sukamandi Experimental Station of BBRMP Padi using a Split-split Plot Design. The treatments included NPK combinations (main plot; without NPK, +PK, +NP, +NK, +NPK), OM (sub-plots; manure, straw compost, without OM), and foliar-applied CDs (800 mg L⁻¹) (sub-sub-plots; +CDs, without CDs). The results showed that coffee ground-based CDs from coffee shops were water-soluble, light brown, and had an absorption peak at 300 nm. Nitrogen doping with urea increased the N content from 2,44% to 16,12%. The N and P significantly improved vegetative growth, grain yield, and seed quality, while N and K maintained chlorophyll in the reproductive stage. OM increased NPK efficiency and nutrient availability, with manure more effective than straw compost. CDs enhanced OM in increasing leaf area. The combination of NPK, OM, and CDs shows potential as an efficient and sustainable fertilization strategy to increase rice productivity and seed quality.

Pengaruh penyerbukan antar spesies kopi yang dibudidayakan terhadap karakteristik buah dan biji
type: item
description: Interspecific pollination between Arabica coffee (Coffea arabica L.) and its diploid relatives are hypothesized to influence the resulting fruit and seed characteristics. To evaluate this effect, artificial interspecific pollination was conducted between C. arabica × C. canephora (A×C), C. arabica × C. liberica (A×L), and their reciprocals (C×A and L×A). As a control, intraspecific pollinations were also performed within C. arabica (A×A), C. canephora (C×C), and C. liberica (L×L). Morphometric traits observed included fruit weight, fruit length, fruit width, fruit thickness, fruit volume, number of seeds per fruit, and abnormalities in fruit and seed development. The mean values were statistically compared using t-tests. The results demonstrated that fruit weight and size from interspecific pollinations with maternal excess (A×C and A×L) were significantly smaller than those from intraspecific pollination within C. arabica. Fruit abnormalities, particularly the percentage of empty fruits, were markedly higher in interspecific combinations—regardless of whether maternal or paternal excess was involved—compared to intraspecific pollinations. However, no consistent association was found between the occurrence of single-seeded fruits (peaberries) and the direction or type of interspecific pollination. Thus, in addition to genetic implications, the results of this study can also provide agronomic implications. ABSTRAK Penyerbukan antar spesies kopi Arabika (Coffea arabica L.) dengan spesies kerabat yang bersifat diploid diduga berpengaruh terhadap karakteristik buah dan biji.

Respons tomat (Solanum lycopersicum l.) terhadap KH₂PO₄ dan giberelin pada hidroponik dutch bucket
type: item
description: Tomato (Solanum lycopersicum L.) is a horticultural commodity which the quality and the yield can be enhanced through the application of the Dutch bucket hydroponic system, along with KH₂PO₄ fertilization and gibberellin hormone treatments. This study aimed to evaluate the response of tomato plants in terms of productivity and quality under these treatments. The experiment was conducted in a greenhouse using factorial randomized complete block design with three replications. The first factor was KH₂PO₄ concentration at three levels: 0 ppm, 150 ppm, and 250 ppm; the second factor was gibberellin concentration at three levels: 0 ppm, 50 ppm, and 100 ppm. Data were analyzed using ANOVA and DMRT on parameters including number of flowers, number of fruits per plant, fruit diameter, average fruit weight, total fruit weight per plant, and total soluble solids value. The results indicated that the interaction of 150 ppm KH₂PO₄ and 50 ppm gibberellin produced optimal values for fruit weight per fruit of 41.32 g, total fruit weight per plant of 398.67 g, and total soluble solids of 6.28 °Bx. Furthermore, either individual effects of KH₂PO₄ or gibberellin concentrations significantly influenced all observed variables except on fruit diameter. Combination KH2PO4 150 ppm and gibbereilin 50 ppm is recommended for enhancing tomato cultivation performance under the Dutch bucket hydroponic system.

Smart-dose microboost: micronutrient in order to enhance chili growth and yield in tropical farming systems
type: item
description: Despite the fact that micronutrients are crucial for the growth, metabolism, and crop yield of plants, they are required in relatively small proportions. The recent advancements in agriculture have resulted in the development of biostimulant products that are abundant in micronutrients which is advantageous. The objective of this investigation was to evaluate the potential of micronutrient-enriched biostimulants (MB) to enhance the quality characteristics of chili fruits. This study was conducted at Jatinangor, West Java. The experimental plots were laid out in a Randomized Block Design (RBD) with seven treatments and repeated four times, so the total number of treatments was 28 units. The treatments consist of farmer practice and doses of 0.75; 1.0; 1.5; 2.0; 2.5 and 3.0 L ha-1 MB. The results of this experiment indicated that the treatments with doses of 2.0–3.0 L ha-1 were consistently preferable in terms of fruit quality, yield, and growth. Plants that were more productive, capable of grading fruit, and had a slightly extended shelf life after harvest were the final result of the biostimulant product, which contained micronutrients. The farmer's practice consistently failed to meet the standards of all the treated sites. The combination of biostimulants and micronutrients significantly enhanced the physiological and reproductive functions of chilies. ABSTRAK Mikronutrien, meskipun dibutuhkan dalam jumlah yang kecil daripada makronutrien, penting untuk perkembangan tanaman, fungsi metabolisme, dan produktivitas tanaman.

Rhizospheric Bacillus spp. as biocontrol agents against maize downy mildew and growth promoters
type: item
description: Downy mildew is one of the major patogen limiting maize productivity in Indonesia. Effective mitigation strategies are essential due to the significant yield losses it causes. Biological control is an environmentally viable alternative method of disease management. Bacillus spp. are biological control agent capable of producing metabolic chemicals that can inhibit plant infections, hence holding potential for downy mildew management. This study aimed to evaluate the effectiveness of Bacillus spp. from the maize rhizosphere to manage downy mildew and promote maize plant growth. The research employed a completely randomized block design, consisting of four treatments and six replications. The treatments comprised Bacillus amyloliquefaciens BB.R3, B. subtilis BK.R5, Bacillus spp. BK.R9, fungicides treatment (metalaxyl), and control group for comparison. The observed variables included spore germination, incubation period, disease incidence, disease severity, Area Under Disease Progression Curve (AUDPC), number of leaves, plant height, fresh shoot weight, and fresh root weight. The findings revealed that B. amyloliquefaciens BB.R3, B. subtilis BK.R5, and Bacillus spp. BK.R9 effectively inhibited downy mildew by decreasing spore germination by 80.55-100%, prolonging the incubation period, and inhibiting disease incidence by 20.37-53.70%, disease severity by 25.64-62.56%, and AUDPC by 22.21-63.37%. B. amyloliquefaciens BB.R3 can enhance plant growth by augmenting root weight by 122.63% and maize plant weight by 80.26%.
