Abstract

Coffee is one of the leading commodities in the plantation subsector in North Sumatra which has good market opportunities both domestically and abroad. Especially in the Lake Toba area, apart from the PBKo pest, it turns out that attacks by the coffee leaf sucking pest Helopeltis sp. are also felt to be very important by farmers, because the presence of Helopeltis sp. This causes the coffee leaf shoots to develop brown spots, curl and eventually dry out and die (die back). The aim of the research was to study the symptoms of attacks and the intensity of Helopeltis sp. attacks on Arabica coffee plants in the Lake Toba area, North Tapanuli Regency. This research was carried out on people's coffee plantations in North Tapanuli Regency at an altitude of 1,300 meters above sea level, from February to June 2023. On the Sigarar Utang variety Arabica coffee plantation with monoculture and polyculture planting patterns. The sample plants were determined to be 10% of the total plants at each observation location. Sampling of plant samples is determined using a zig zag line. The parameters observed were the intensity of attacks and the percentage of pest attacks. The results obtained by Helopeltis sp. sucking shoot pests have been known to attack coffee plants in North Tapanuli Regency with symptoms of attack. At the start of the attack, leaf spots are visible, brown, curly and eventually dry out, die back, then grow rosettes, namely shoots, new ones that are shortened tightly and do not develop. The intensity of attacks by Helopeltis sp. on smallholder coffee plantations in North Tapanuli Regency is quite varied, from light to heavy attacks with the intensity of shoot attacks ranging from 15.67% to 57.80%. Monoculture coffee plantations with protective plants, but no pruning, are locations with Helopeltis sp. attack levels in the heavy category with shoot attack intensity reaching 56.66%. The intercropping coffee plant cultivation system (polyculture) had a significant influence on the low intensity of Helopeltis sp. attacks, where tcount (8.921) > ttable (2.306).

Abstract

The coconut palm (Cocos nucifera) is an economically and culturally significant crop widely cultivated in tropical regions, particularly in Indonesia. However, coconut productivity remains suboptimal due to aging plantations and poor soil conditions. To address this, biofertilizers such as Bacillus nigr have been proposed as sustainable alternatives to chemical fertilizers. This study aimed to evaluate the effect of Bacillus nigr-based liquid organic fertilizer (POC) on the early growth parameters of coconut plants aged 9 to 12 months. Conducted in Deli Serdang, North Sumatra, the experiment involved 38 coconut seedlings divided equally into treatment (POC) and control groups. Data on stem height were collected and analyzed using a T-test. The results demonstrated a statistically significant difference (p < 0.05) in stem height between the POC-treated and untreated plants, with notable growth advantages observed in the control group at 11 and 12 months. However, POC treatment showed promising effects at earlier growth stages (9–10 months). These findings suggest that Bacillus nigr-based POC may influence early vegetative growth, but long-term benefits and dosage optimization require further investigation. This study contributes to the growing body of knowledge on the role of microbial biofertilizers in sustainable coconut cultivation and offers insights for enhancing early-stage coconut growth using environmentally friendly agricultural practices.

Abstract

Abstrak Penggunaan pestisida sintetis secara intensif masih menjadi salah satu strategi utama dalam pengendalian organisme pengganggu tanaman. Namun, penggunaan jangka panjang dapat menimbulkan dampak negatif terhadap lingkungan, kesehatan manusia, resistensi hama, serta penurunan keanekaragaman hayati. Bioteknologi mikroba menawarkan pendekatan alternatif melalui pemanfaatan mikroorganisme potensial sebagai agen biopestisida ramah lingkungan. Artikel review ini bertujuan untuk membahas peran bioteknologi mikroba dalam pengembangan biopestisida berbasis bakteri, cendawan, virus, dan aktinomiset, serta kontribusinya terhadap sistem pertanian berkelanjutan. Metode yang digunakan adalah kajian literatur terhadap artikel ilmiah, regulasi, dan laporan terkait biopestisida mikroba, mekanisme kerja, formulasi, aplikasi lapangan, serta tantangan komersialisasi. Hasil kajian menunjukkan bahwa mikroba seperti Bacillus thuringiensis, Bacillus subtilis, Pseudomonas fluorescens, Trichoderma spp., Beauveria bassiana, Metarhizium anisopliae, dan Streptomyces spp. memiliki potensi besar sebagai agen pengendali hayati melalui mekanisme antibiosis, kompetisi, mikoparasitisme, produksi enzim litik, produksi metabolit sekunder, serta induksi ketahanan sistemik tanaman. Pengembangan biopestisida mikroba masih menghadapi kendala berupa stabilitas formulasi, konsistensi efektivitas di lapangan, regulasi, umur simpan, serta penerimaan petani. Oleh karena itu, integrasi bioteknologi mikroba, formulasi modern, pendekatan omics, dan sistem pengendalian hama terpadu menjadi strategi penting dalam memperkuat pemanfaatan biopestisida untuk pertanian berkelanjutan. Kata kunci: bioteknologi mikroba; biopestisida; agen hayati; pertanian berkelanjutan; pengendalian hayati. Abstract The intensive use of synthetic pesticides remains one of the main strategies for controlling plant pests and diseases. However, long-term application may cause environmental degradation, pest resistance, biodiversity loss, and potential risks to human health. Microbial biotechnology offers an alternative approach through the utilization of beneficial microorganisms as environmentally friendly biopesticides. This review aims to discuss the role of microbial biotechnology in the development of biopesticides based on bacteria, fungi, viruses, and actinomycetes, as well as their contribution to sustainable agriculture. The method used in this study was a literature review of scientific articles, regulations, and reports related to microbial biopesticides, mechanisms of action, formulation, field application, and commercialization challenges. The review shows that microorganisms such as Bacillus thuringiensis, Bacillus subtilis, Pseudomonas fluorescens, Trichoderma spp., Beauveria bassiana, Metarhizium anisopliae, and Streptomyces spp. have strong potential as biological control agents through antibiosis, competition, mycoparasitism, lytic enzyme production, secondary metabolite production, and induced systemic resistance. Nevertheless, microbial biopesticide development still faces several challenges, including formulation stability, field efficacy consistency, regulation, shelf life, and farmer acceptance. Therefore, integrating microbial biotechnology, modern formulation, omics approaches, and integrated pest management is essential to strengthen the role of microbial biopesticides in sustainable agriculture.

Abstract

This research aims to examine the production of superior oil palm seed bunches in the PPKS Marihat Unit.Data and information collection is carried out using direct and indirect methods. Field observations carried out include: Area conditions including: topography, soil conditions, Plant conditions including: plant growth, plant population and fruit condition, Technical culture conditions: fertilization, harvesting of seed bunches. Supporting data collected includes: garden production data, rainfall and fertilization data. The research results are bSeveral factors that cause low production include: a) fertilizer amounts that are far from plant needs, given the time, type; b) plant density which is classified as less than optimal due to ganoderma attacks. The number of bunches is the result of plant physiological processes, mainly determined by the ecophysiological conditions of the plant around 24 months before harvest, where the decrease in production in the number of bunches harvested in 2020 is the result of ecophysiological conditions in the form of fertilization which is not appropriate in 2019-2020.

Abstract

The vegetative growth of melon (Cucumis melo L.) grown in hydroponic systems is influenced by proper nutrient management and the application of plant growth regulators. This study aimed to evaluate the effects of AB Mix nutrient concentration, gibberellic acid (GA₃), and their interaction on the vegetative growth of melon cultivated in a Dutch Bucket hydroponic system. The experiment was conducted at the CV. BestFarm Greenhouse, Deli Serdang Regency, North Sumatra, Indonesia, from December 2025 to March 2026 using a factorial Completely Randomized Design (CRD). The treatments consisted of three AB Mix concentrations (1800, 2200, and 2600 ppm) and four GA₃ concentrations (0, 40, 60, and 80 ppm). The results showed that AB Mix had a highly significant effect on several vegetative growth parameters, including plant height, number of leaves, leaf area, stem diameter, and vine length, with 2200 ppm producing the optimum vegetative growth. GA₃ application and its interaction with AB Mix had no significant effect on all observed vegetative growth parameters. These findings indicate that optimum AB Mix nutrition plays a more important role than GA₃ application in improving the vegetative growth of melon cultivated under a Dutch Bucket hydroponic system.
