Abstract

[GENETIC VARIABILITY AND HERITABILITY OF 10 ACCESSIONS OF BIRD’S EYE CHILI (Capsicum frutescens L.) GROWN ON COASTAL LAND]. Cultivation of bird’s eye chili (Capsicum frutescens L.) on saline coastal land in Indonesia faces several environmental constraints. Efforts to increase bird’s eye chili productivity in saline land are by planting varieties that are adaptive to stressed environmental conditions. This research aims to evaluate performance, estimate genetic diversity and heritability of agronomic traits in 10 bird’s eye chili accessions in coastal land in Kuala Alam, Bengkulu. The research was conducted using a one-factor Randomized Complete Block Design (RCBD) with 10 accessions as treatments and three replications. The results showed that the characters of plant height, stem diameter, flowering date, dichotomous height, fruit length and fruit diameter had wide genotypic variation. Broad phenotypic was shown by all characters. High heritability values were obtained in the characters of plant height, stem diameter, flowering date, dichotomous height, number of dichotomous points, fruit length and fruit diameter. The characters of number of leaves, leaf greenness, number of fruits per plant and fruit weight per plant have medium heritability values. The number of stomata and stomatal density characters have low heritability values. Accession Bangka 2 has superior performance in the characters of plant height, stem diameter, flowering date, dichotomous height, number of dichotomous point, fruit length, fruit diameter and fruit weight per plant. Accessions with superior performance and characters that have high heritability values with a wide genotypic and phenotypic range are used as elders in plant breeding programs. These findings form the basis for the development of superior bird’s eye chili varieties that are adaptive to saline land. Full text pdf

Abstract

[EFFECTIVENESS OF SEED COATING ON EXPIRED ‘BARA’ BIRD’S EYE CHILI (Capsicum frutescens L.) SEEDS]. The decline in physiological quality of bird’s eye chili (Capsicum frutescens L.) seeds due to prolonged storage poses a significant challenge in horticultural crop production, particularly in ensuring the availability of high-quality seeds. This study aimed to evaluate the effectiveness of seed coating using carboxymethyl cellulose (CMC) and humic acid in combination with Plant Growth Promoting Rhizobacteria (PGPR) in enhancing the viability and vigor of aged ‘Bara’ chili seeds. The experiment was conducted from March to June 2025 at the laboratory, field, and greenhouse facilities of the UPT for Rice and Palawija Seed Development, Singosari, Malang, East Java. A factorial completely randomized design (CRD) was employed with two factors: type of coating material (CMC, humic acid, and CMC + humic acid) and PGPR dosage (10 g and 20 g). The observed variables included maximum growth potential, germination rate, vigor index, and seedling growth rate. The results indicated that treatment with 1% humic acid + 20 g PGPR yielded the highest maximum growth potential and germination rate (100%), while the combination of 1% humic acid + 10 g PGPR produced the highest vigor index (33.33%) and growth rate (5.89%/day). The application of organic coating materials combined with PGPR was proven effective in restoring the physiological quality of aged chili seeds. These findings can be implemented as a seed invigoration strategy to extend the shelf life of horticultural seeds and improve seedling establishment under field conditions, thereby supporting sustainable crop production systems.

Abstract

[IDENTIFICATION OF SPECIES AND POPULATION OF ARBUSCULAR MYCORRHIZAL FUNGI IN SUGARCANE PLANTATIONS AT PG. REJO AGUNG BARU, MADIUN]. Arbuscular Mycorrhizal Fungi (AMF) play an important role in enhancing plant root capacity for nutrient uptake. This study aimed to identify the species and determine the population of AMF in sugarcane fields at PG. Rejo Agung Baru, Madiun. Observations were conducted on four fields with different productivity levels: very high, high, moderate, and low. The research employed a quantitative descriptive approach with an exploratory method. Soil and root samples were analyzed to determine AMF species and population density, while the relationships between AMF populations and soil properties were examined using simple linear regression and t-tests. The results revealed that all sites contained the same AMF species, Glomus sp., which exhibited a high adaptability to various soil fertility conditions. The highest AMF population was observed in the very high productivity field (1.01 × 10⁷ spores/ha), whereas the lowest was found in the moderate productivity field (0.06 × 10⁷ spores/ha). Population variations were influenced by interactions among soil physical and chemical properties, particularly pH, organic carbon, total nitrogen, and clay fraction. Overall, this study demonstrates that the occurrence and population density of AMF, especially Glomus sp., are strongly affected by soil conditions. Optimal AMF populations were associated with soils characterized by near neutral pH, high organic matter content, low clay fraction, and moderate nitrogen levels, suggesting that these factors are critical for enhancing AMF activity in sugarcane cultivation.

Abstract

[CONCENTRATION OF LOCAL ENTOMOPATHOGENIC NEMATODE Steinernema carpocapsae Weiser AGAINST CORN COB BORER Helicoverpa armigera Hübner IN LABORATORY BIOASSAYS]. Corn (Zea mays L.) ranks among Indonesia's most vital food crops. However, production in Riau Province has declined due to infestations by the corn cob borer (Helicoverpa armigera Hübner), which can damage up to 39.7% of crops. Conventional control relies on synthetic chemical insecticides, which pose persistent risks including mortality of natural enemies, pest resistance, and population resurgence. An eco-friendly alternative involves local entomopathogenic nematodes (EPN), Steinernema carpocapsae Weiser, which induce rapid host mortality (within 24–48 hours) via symbiotic bacteria producing lethal toxins. This study determined the best concentration of S.carpocapsae infectious juveniles (IJ) for H. armigera mortality under laboratory conditions. An experimental approach employed a completely randomized design (CRD) with five concentrations (0, 250, 500, 750, and 1000 IJ/mL distilled water) and four replicates per treatment. Parameters assessed included EPN identification, time to initial mortality, and total mortality. Data were subjected to analysis of variance (ANOVA) followed by DNMRT test at 5% significance. Results revealed that 750 IJ/mL was the most effective concentration, achieving 80% total mortality within 72 hours post-application. These findings support S. carpocapsae at 750 IJ/mL as a viable biocontrol agent for H. armigera in integrated pest management (IPM) programs, warranting field trials to validate efficacy under Riau's agroecological conditions.

Abstract

[EFFECT OF SEED COATING ON MAINTAINING VIABILITY OF RED GUAVA (Psidium guajava L.) SEEDS DURING STORAGE]. Guava (Psidium guajava L.) is one of the potential intercropping options for a revegetation programme. Hydrophilic polymer coating and several additional materials are expected to increase the vigor of seeds planted by direct sowing under suboptimal conditions. However, it is necessary to study its effect on seed viability during storage, especially on guava seeds which are classified as intermediate seeds.This study aims to determine the effect of coating on the viability of guava seeds (Psidium guajava L.) during storage. The experiment was arranged in a factorial randomized complete block design (RCBD) with two factors: coating materials (control, alginate, tapioca, alginate + manure pelleting, alginate + vermicompost pelleting, tapioca + manure pelleting, and tapioca + vermicompost pelleting) and storage periods (0, 2, and 4 weeks) in polyethylene bags. The results showed that storage for more than two weeks caused a sharp decrease in germination percentage and vigor index. Coating treatment with alginate for two weeks is more effective in maintaining water content, germination percentage, and seed vigor. Seed coating with alginate is recommended method for extending shelf life while maintaining the physiological quality of guava seeds. Pelleting using alginate and vermicomposting were not significantly different from coating treatment with alginate in the same parameters, so both treatments can be recommended as neede

Abstract

[OPTIMIZING CORN (Zea mays L.) GROWTH THROUGH FERTILIZATION BASED ON IOT SOIL SENSOR ANALYSIS. Corn (Zea mays L.) plays an important role in Indonesia's agricultural sector as a source of food, animal feed, and industrial raw materials. However, the main challenge in cultivation is improper fertilization, which can reduce yields and damage the environment. Efficient and sustainable fertilization is necessary to increase productivity. Internet of Things (IoT)-based soil sensor technology provides a solution by providing accurate data on soil conditions that help with fertilization efficiency. The purpose of this study was to examine the effect of fertilization variations adjusted to the results of IoT-based soil sensor analysis on corn plant growth. The study was conducted in Labanasem Village, Banyuwangi Regency, from July to September 2025, using a non-factorial randomized block design (RBD) with four treatments, namely conventional, chemical, balanced, and organic fertilization, repeated six times. Data were collected using IoT soil sensors to analyze pH, moisture, temperature, and nutrients. Fertilization was carried out at 20, 35, and 55 days after planting for conventional and chemical fertilizers, while balanced and organic fertilizers followed the dosage recommendations from the IoT system. The results showed that balanced fertilization did not differ significantly from conventional and chemical fertilization in terms of plant growth parameters, including plant height, number of leaves, stem diameter, leaf area, leaf area index, and flowering age (p > 0.05). Organic fertilization showed significantly different results (p < 0.05), but balanced fertilization was more efficient in reducing input costs and supporting agricultural sustainability compared to organic fertilization, as well as supporting agricultural sustainability. IoT-based soil sensor technology can improve fertilization precision and support fertilizer use efficiency.based soil sensors and balanced fertilization is recommended to increase corn production efficiently and sustainably.

Abstract

Soil macrofauna are an essential biotic component that plays a significant role in maintaining soil ecosystem balance. They are also among the most sensitive indicators of land-use change and can therefore be utilized as markers or predictors of soil quality. The diversity and abundance of soil macrofauna are generally influenced by environmental conditions, particularly vegetation covering or shading above the soil surface. Coffee cultivation in Solok Radjo, Kabupaten Solok, Sumatra Barat, is typically carried out under shade provided by various tree species. This study aimed to examine the diversity, abundance, and composition of soil macrofauna within coffee cultivation systems under different types of shade in Solok Radjo. The research was descriptive in nature and employed an exploratory method, with sampling conducted directly in the field using manual hand sorting. The shade conditions observed included unshaded, shade Paraserianthes falcataria, shade Eucalyptus sp., and shade Leucaena leucocephala. The findings revealed two phyla of soil macrofauna comprising 4 classes, 8 orders and 9 families. Soil macrofauna in coffee plantations with shades of Falcataria moluccana and Leucaena leucocephala trees had higher family counts, abundance, diversity index, and richness index compared to Eucalyptus sp. trees and unshaded. The evenness index was even across all shade types, with no dominant species. The organic carbon content was highest in the shaded areas of Falcataria moluccana trees. Agroforestry systems of coffee plants with shaded areas of Falcataria moluccana and Leucaena leucocephala trees can be implemented to stabilize microclimate conditions and increase litter volume, macrofauna biodiversity, and soil fertility.

Abstract

[FRUIT FLY CONTROL INNOVATION FOR CRYSTAL GUAVA AGROTOURISM DEVELOPMENT ON PEATLANDS]. Sebangau District, Palangka Raya City, is developing agrotourism for picking crystal guava  (Psidium guajava L. var. ‘Crystal’) on peatlands, but attacks by fruit flies of the genus Bactrocera spp. have caused crop losses of up to 40-60% globally. This study aims to evaluate the effectiveness of combined attractants to attract male and female fruit flies and measure their impact on the quality of crystal guava fruit. The study was conducted in two stages on four farmers' fields (2024). Stage I: collection of fruit flies using Steiner traps with three attractants: methyl eugenol (ME), processed cocoa waste with preservatives (PCWWP), and mango extract (MGE), each with 20 replicates/location, 4 weeks. Stage II: fruit quality testing (vitamin C content, reducible sugar, hardness, crispness, organoleptic test of 20 panelists) from the best trap-protected plants. The results showed that 31,759 fruit flies were trapped, dominated by Bactrocera carambolae (98.53%), B. umbrosa (1.34%), and B. cucurbitae (0.13%). The ME+PCWWP combination was the most effective (p<0.01), capturing 99.84% of the male population including 0.16% of the females. Fruit from this treatment had the highest vitamin C (153.6 mg/100g), reducible sugar (9.9°Brix), best organoleptic preferences for hardness (5.2), crispness (4.8), taste (6.1), and overall (scale 5.9/6). Female B. cucurbitae were more attracted to ME+MGE (ratio 1:5). The combination of ME+OLK is recommended for sustainable fruit fly control in peatland crystal guava agrotourism, improving fruit quality and tourist attraction.

Abstract

[GROWTH AND YIELD RESPONSE OF MUSTARD GREENS (Brassica juncea L.) TO COMBINED APPLICATION OF CHICKEN MANURE EXTRACT, RABBIT URINE EXTRACT, AND AB-MIX NUTRIENT SOLUTION IN AN NFT HYDROPONIC SYSTEM]. Hydroponic cultivation offers several advantages over conventional agricultural practices, including the production of clean produce, accelerated plant growth, improved crop quality, and increased yield. Moreover, hydroponic systems provide a cost-effective approach for vegetable production with distinct agronomic benefits. This study aimed to evaluate alternative nutrient formulations to partially replace AB-Mix fertilizer using chicken manure extract and rabbit urine extract. The experiment was conducted in a field garden located in Labuhan Ratu District, Bandar Lampung City, from June to July 2024. A Completely Randomized Design (CRD) was employed, consisting of four treatments with six replications, involving a total of 144 mustard green plants. The treatments included: (1) 75% AB Mix + 25% chicken manure extract; (2) 75% AB Mix + 15% chicken manure extract + 10% rabbit urine extract; (3) 50% AB Mix + 30% chicken manure extract + 20% rabbit urine extract; and (4) control (100% AB Mix). Data were subjected to a homogeneity test using Bartlett’s test. Upon meeting the assumptions, analysis of variance (ANOVA) was performed, followed by mean separation using the Least Significant Difference (LSD) test at a 5% significance level. The results indicated that the application of 75% AB Mix combined with 25% chicken manure extract, as well as 75% AB Mix combined with 15% chicken manure extract and 10% rabbit urine extract, showed no significant difference compared to the control (100% AB Mix). In contrast, the treatment consisting of 50% AB Mix combined with 30% chicken manure extract and 20% rabbit urine extract differed significantly from the control. These findings suggest that partial substitution of inorganic AB Mix fertilizer with organic nutrient sources, such as chicken manure extract and rabbit urine extract, has the potential to reduce dependence on inorganic fertilizers in hydroponic systems.

Abstract

[GROWTH AND YIELD OF BISI 18 MAIZE AS AFFECTED BY PACLOBUTRAZOL APPLICATION AND NITROGEN FERTILIZATION]. Maize (Zea mays L.) is a vital commodity in Indonesia that requires higher productivity. Tall-growing hybrid maize is prone to lodging; therefore, paclobutrazol can be used to suppress vegetative growth, while nitrogen supports plant growth and yield. This study aimed to determine the optimal paclobutrazol concentration and nitrogen fertilizer rate for the growth and yield of BISI 18 maize. The experiment was arranged in a split-plot design with two factors: paclobutrazol concentrations (0, 1250, 1500, and 1750 ppm) and nitrogen fertilizer rates (350, 400, 450, and 500 kg/ha). Paclobutrazol was applied as a foliar spray at 18 and 37 days after planting (DAP), while nitrogen fertilizer was applied by dibbling at 14, 35, and 49 DAP. Data were analyzed using analysis of variance (ANOVA) followed by the Honestly Significant Difference (HSD) test at the 5% level. The results showed a significant interaction between paclobutrazol concentration and nitrogen rate, with different optimal combinations for each parameter. The combination of 1750 ppm paclobutrazol and 350 kg/ha nitrogen produced the shortest plants, while 1750 ppm paclobutrazol with 450 kg/ha nitrogen resulted in the highest number of leaves. The earliest tasseling occurred with 1250 ppm paclobutrazol and 500 kg/ha nitrogen. A nitrogen rate of 450 kg/ha produced the highest grain weight per plant and per plot, increasing dry grain yield to 10.69 t/ha. Increasing paclobutrazol concentration suppressed plant height; however, excessive concentrations and nitrogen rates may inhibit growth. Paclobutrazol concentrations of 1250–1500 ppm combined with 450 kg/ha nitrogen were sufficient to achieve optimal growth and yield.
