Abstract

Bogor bean (Vigna subterranea (L.) Verdc.) are plants that have many advantages. Bogor beans are easy to cultivate because they are tolerant to water and nutrient limitations. Bogor beans have good nutritional content, namely high carbohydrate and protein and relatively low fat, so they can be used as an alternative food source. In addition, Bogor beans can also be used as an alternative crop for dry land cultivation. This study aims to select superior individuals from the Bogor bean populations originating from Sukabumi and Sumedang and to determine the closeness of the relationship between two variables in the Bogor bean populations originating from Sukabumi and Sumedang. This study used an experimental method without a specific environmental design and was designed by dividing the planting plots into two large plots differentiated by population origin. The characteristics observed included the number of leaves, canopy width, plant height, fresh pod weight, dry pod weight, number of pods per plant, number of filled pods, number of empty pods, fresh pod weight, pod length and width, seed length and width, and weight of 100 seeds. This study was conducted at the Teaching and Research Farm of the Faculty of Agriculture, University of Jambi, Unja Mendalo Campus, Jambi Luar Kota District, Muaro Jambi Regency from September 2024 to March 2025. The data obtained were analyzed using the coefficient of variation, mean value, t-test, differential selection, and correlation. The results show that of the 10 superior individuals selected from the original population in Sukabumi, they include A1, A2, A11, A31, A37, A46, A52, A57, A81, A82, while in the Sumedang population they included B6, B21, B35, B39, B44, B55, B56, B64, B68, B77. The Sukabumi population, when compared to the Sumedang population, has superior characteristics based on the variables of fresh pod weight, dry pod weight, number of pods per plant, and number of mature pods. Meanwhile, the Sumedang population, when compared to the Sukabumi population, has superior characteristics based on the variables of fresh pod weight, pod length, seed length, and weight of 100 seeds.

Abstract

Sugarcane is one of the main crops in the plantation sector in Indonesia which has high economic value in sugar industry. One of the factors that disrupts the growth and yield of sugar cane is the interference of weeds during the cultivation period. The aim of this research was to determine the growth of sugarcane in response of a weed-free period. The research used a Randomized Complete Block Design (RCBD) with 6 treatments and 4 replications. The treatments are free from weeds along 3 months after planting (MAP), free from weeds along 6 MAP, free from weeds along 9 months MAP, weedy along 3 MAP, weedy 6 MAP, and weedy along 9 MAP. Observations were made on weed growth and vegetative growth of sugarcane until 9 MAP. The data obtained were analyzed using analysis of variance and continued with the Least Significant Difference (LSD) test at 5% level. The analysis found that the dominant weeds in sugarcane plantations at the research location were grasses, namely Brachiaria mutica, Digitaria ciliaris, and Paspalum conjugatum. Furthermore, we concluded that the weed-free period increases sugarcane germination and growth. At 9 months after planting, weed-free sugarcane for 9 months and weeded sugarcane for 3 months produced the highest sugarcane populations, reaching 83,949 and 78,952 per hectare, respectively. The highest stem diameter was obtained in weed-free for 3, 6, and 9 months after planting. The highest sugarcane were obtained in weed-free for 3, 6, and 9 months after planting, and in weedy for 3 months after planting. Weed control during the 3-6 months after planting increased sugarcane germination, population, stem diameter, and plant height. The critical period for weed control in sugarcane ranges from 2 to 6 months after planting. Keywords: critical period, weeding, weeds, sugarcane

Abstract

Cocoa (Theobroma cacao L.) is a strategic plantation commodity contributing significantly to Indonesia’s economy. Pesawaran Regency, one of the cocoa production centers in Lampung Province, faces biophysical challenges related to rainfall variability and heterogeneous land-suitability conditions. This study aimed to analyze rainfall patterns and variability from 2016–2022, evaluate cocoa productivity trends, assess agroclimatic and land suitability characteristics, and examine the relationship between rainfall and cocoa productivity. The research was conducted in November–December 2024 using secondary data on annual rainfall, cocoa productivity (2016–2022), and land suitability parameters. Data were analyzed using descriptive statistics, land suitability evaluation, Pearson correlation, and simple linear regression. Results showed that annual rainfall ranged from 1,827–2,250 mm/year, remaining within the optimal range for cocoa cultivation. Productivity increased from 719 kg/ha (2016–2017) to 1,106 kg/ha (2018), stabilized at approximately 1,174 kg/ha (2019–2021), and declined to 876 kg/ha in 2022. Land suitability classes ranged from S1 to S3, with major limiting factors including acidic soil pH, low–moderate phosphorus availability, limited nutrient retention, and erosion risk. Correlation analysis revealed a very weak relationship between rainfall and productivity (r = –0.096; R² = 0.009) with the regression equation Y = 1266.94 – 0.135X. These findings indicate that cocoa productivity dynamics in Pesawaran Regency are more strongly influenced by land conditions and management practices than by annual rainfall variability.

Abstract

Rice paddy agroecosystems serve as habitat for diverse predatory insect communities that play a critical role in natural pest regulation. This study aimed to analyze the community structure and trophic interaction patterns of predatory insects in the irrigated rice agroecosystem of Gampong Gintong, Grong-Grong District, Pidie Regency, Aceh. Sampling was conducted during three rice growth phases (35, 45, and 55 days after transplanting/DAT) using pitfall traps, yellow pan traps, and sweep nets in five 20×20 m observation plots. A total of 1,468 individual predatory insects were collected, representing 30 families and 7 orders. Formicidae dominated the assemblage at 79.77% of total individuals with stable abundance throughout the growing season. The Shannon-Wiener diversity index (H') ranged from 0.7624 to 0.9275, indicating low to moderate diversity with no significant differences among phases (p = 0.075). In contrast, Simpson's dominance index (C) and Pielou's evenness index (E) differed significantly among growth phases (p < 0.01), reflecting progressive Formicidae dominance associated with canopy development. Sørensen similarity indices (Cs = 0.5882–0.7222) confirmed high stability of the core predator assemblage across all phase comparisons. Trophic network reconstruction identified ten key predator families operating across three distinct vertical zones with complementary diurnal-nocturnal activity patterns. These findings highlight the importance of vegetated refugia conservation at field bunds and reduction of broad-spectrum insecticide use as a foundation for sustainable integrated pest management (IPM).

Abstract

Shallots (Allium ascalonicum L.) are one of the important horticultural commodities that often experience unstable harvest yields due to land quality degradation triggered by the massive and continuous use of chemical inputs. This study aims to identify the effect of planting media and Trichoderma sp. on the growth process and productivity of Bima Brebes shallots. This study was arranged in a two-factorial Randomized Block Design (RBD) (3 x 4) with three replications. The first factor was the media composition (soil, sand, rice husk charcoal, and goat manure). The second factor was Trichoderma sp. with doses of 0, 7.5, 15, and 22.5 g/polybag. The results of this study showed that the planting media treatment had a significant effect on almost all observed parameters. The use of media enriched with goat manure (C2 and C3) was able to increase the variables of plant height, number of leaves, bulb weight, bulb diameter, and root weight. The C2 medium showed the highest wet bulb yield of 31.54 g/polybag, while the C1 medium showed the lowest yield of 15.92 g/polybag. Conversely, the administration of various doses of Trichoderma sp. showed no effect on any of the observed parameters, and the two treatments showed no interaction. This is likely due to the low organic matter content, which limited the colonization of biological agents. The growth and yield of shallot bulbs were more optimal through the addition of media amendments such as goat manure to improve chemical and physical properties compared to the single application of Trichoderma.

Abstract

During storage, bean seeds (Phaseolus vulgaris L.) will continue to experience viability decline. One effort to slow down the rate of decline is the use of appropriate packaging materials. This study aims to determine the type of packaging that can maintain high bean seed viability during the storage period of 0-8 months at room temperature of approximately ±28°C. The research was conducted from September 2020 to May 2021, at the Seed and Plant Breeding Laboratory, Faculty of Agriculture, Lampung University. This study used three types of packaging treatments: aluminum foil (AF), black plastic (PH) polyethylene, and transparent plastic (PB) polypropylene, applied in a Complete Randomized Block Design (CrBD) with five replications. Data analysis was conducted using regression analysis with Sigma Plot 12.0 software to express the equation ŷ=f(x) and the Student's t-test to compare the mean viability of bean seeds from 0-8 months. The results of the study indicate that the comparison of linear coefficient (bi) and mean of each viability variable showed no significant difference between packaging types. In fact, there was a higher decline in viability in black plastic packaging between 4-8 months, ranging from 74.24% to 48.48%. Aluminum foil packaging was able to maintain the highest viability of bean seeds in the 8th month (81.5%), transparent plastic packaging in the 6th month (81.2%), and black plastic packaging in the 2nd month (87.12%). Keywords: viability, packaging, storage duration, aluminum foil, string bean seeds

Abstract

The increase in coffee production in East Belitung Regency indicates that coffee plants are quite prospective for development and preservation. The development of Robusta coffee cultivation can be done through plant exploration and characterization activities to obtain accessions with superior properties. This study aims to determine the value of variability and kinship relationships of Robusta coffee accessions in East Belitung Regency. The study was conducted from July 2025 to January 2026. This study used an exploration method with a purposive sampling technique on five healthy and vigorous Robusta coffee plant samples at each research location. Morphological characterization was carried out based on coffee descriptors for qualitative and quantitative characters. Analysis of kinship relationships based on qualitative characters used the UPGMA method with NTSYS-pc 2.1 software in the form of a dendogram and analysis of variability on quantitative characters to obtain the phenotypic diversity value of Robusta coffee accessions. The results of Robusta coffee plant exploration in East Belitung Regency found eight Robusta coffee accessions including Mentawak 1, Mentawak 2, Kelubi, Batu Penyu, Limbongan, Dendang, Jangkang and Lintang accessions. The results of data analysis found that Robusta coffee accessions in East Belitung Regency have a close kinship relationship based on qualitative characters with a coefficient of 80%, which are divided into four clusters. Robusta coffee accessions have narrow to wide plant variability. Narrow variability is found in the characters of leaf length, number of flowers per fascicle, fruit diameter, number of petals per flower and seed width. Somewhat narrow variability is found in the characters of leaf width, leaf stalk length, dry weight of 100 fruits and seed length. Quite wide variability is found in the characters of fresh weight of 100 fruits, wet weight of 100 seeds and dry weight of 100 seeds. Wide variability is found in the characters of plant height, number of flowers per node and flower stalk length. Robusta coffee accessions obtained can be useful as genetic resources for further development through plant breeding programs in the future.

Abstract

The objective of this study was to determine the distribution pattern of dry matter from leaves to tubers in 10 cassava clones in two different land conditions (optimal and marginal). The experiment was arranged in a factorial randomized completely block design (RCBD) (2x10), with three replications, resulting in 60 experimental units. The variables observed included plant height, stem diameter, number of green leaves, fresh and dry weight of leaves, stems, and tubers. The results of the study indicate that differences in soil conditions and clones influence the distribution pattern of dry matter in cassava plants. The Garuda, UJ3, Sekoci, Soponyono, D9, and Vamas-1 clones exhibited relatively good growth and yield under both soil conditions, while Cino and Waxy performed better on optimal soil, and UJ5 showed good tuber formation only during the early growth stage. The most efficient dry matter distribution was shown by the Garuda and UJ3 clones, which produced the highest tuber weight at 10 months after planting (MAP), followed by Sekoci, Soponyono, D9, and Vamas-1, which were also able to accumulate high amounts of tuber dry matter. Conversely, the KM clone exhibited the lowest dry matter distribution, characterized by the lowest fresh and dry tuber weights under both soil conditions.

Abstract

Sweet corn (Zea mays var. saccharata Sturt.) is a horticultural commodity with high economic value; however, its productivity is often constrained by low nitrogen fertilization efficiency. Excessive use of inorganic nitrogen fertilizers increases production costs and poses environmental risks. This study aimed to evaluate the effect of Gluconacetobacter diazotrophicus (GDB) application on improving nitrogen fertilization efficiency and harvest quality of sweet corn, as well as to determine the most efficient nitrogen dosage. The research was conducted at PT Pandawa Agri Indonesia from May to August 2025 using a Randomized Block Desig with 10 treatment combinations of nitrogen fertilizer rates and GDB application, replicated three times. The observed parameters included cop length, cop diameter, cop weight with and without husk, and biomass weight. Data were analyzed using analysis of variance followed by Duncan’s Multiple Range Test at a 95% confidence level. The results showed that GDB application significantly improved nitrogen use efficiency. The combination of 75% nitrogen fertilizer with GDB produced harvest quality comparable to full nitrogen fertilization, indicating the potential of GDB to support more efficient and sustainable sweet corn cultivation.

Abstract

The demand for palm oil commodities from Indonesia increases every year, making it very influential on the international market.  Despite its very significant contribution to the national economy, oil palm plantations face complex challenges, such as issues of land degradation, destruction of biodiversity, deforestation, and several other environmental issues. Inaccurate oil palm maintenance data which still relies on traditional methods based on historical data and field observations often requires a lot of time and costs, especially due to changes in climate conditions and pest and disease attacks. This research aims to produce a map of palm oil health conditions that can be used for more efficient production management by optimizing quality and quantity. This research was carried out in May-December 2025 in Sambas district spread across 10 sub-districts (Sambas, Sejangkung, Sebawi, Semparuk, Selakau, Subah, Tebas, Sajad, Galing, and Sajingan) using field observation methods and analyzing satellite image data and geographic information systems integrated with soil laboratory analysis data (content of essential nutrients in the soil). The satellite image data used is image data recorded by Landsat 8 OLI in 2025 which was processed using Quantum GIS software, the Indonesian Earth Map (RBI), and the land use map of Sambas district. The research results showed that there were variations in soil nutrient content concentrations and NDVI values ​​which correlated with the health level of oil palm plants with an average range of 0.0202 – 0.4351 (high health level).
