Abstract

Soybean (Glycine max Merril.) is a strategic food crop whose productivity must be improved to meet increasing national demand. The use of Plant Growth Promoting Rhizobacteria (PGPR) offers a promising approach to enhance plant growth and yield. This study evaluated the effects of PGPR types and application frequencies on the growth and yield of the Grobogan soybean variety. The experiment, conducted from June to September 2025, employed a two-factor Randomized Complete Block Design with five PGPR types and three application frequencies. Results showed that PGPR type significantly affected plant height, leaf number, and pod number, while application frequency significantly influenced plant height at 10 WAP and pod number. Bamboo root PGPR produced the best performance, with a plant height of 78.84 cm, 43 leaves, and 110 pods under three applications. These findings demonstrate that bamboo root PGPR is a promising biological agent for sustainably improving soybean productivity.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi jenis serangga hama yang terdapat pada beras eceran serta menganalisis mutu fisik tiga merek beras yang dipasarkan di tiga pasar tradisional di Kabupaten Serang, yaitu Pasar Tirtayasa, Pasar Begog, dan Pasar Dukuh. Penelitian dilaksanakan pada bulan Maret hingga Mei 2025 menggunakan rancangan tersarang (nested design) dengan dua faktor, yaitu lokasi pasar dan merek beras (SLYP Super RL Macho, SLYP Super OS, dan SLYP Super KM Karya Makmur). Parameter yang diamati meliputi jenis dan jumlah serangga hama, rasio jantan dan betina, derajat sosoh, kadar air, serta jumlah benda asing. Hasil pengamatan menunjukkan bahwa Sitophilus oryzae merupakan spesies dominan yang ditemukan pada seluruh sampel dengan jumlah populasi tertinggi pada merek RL Macho di Pasar Tirtayasa. Kondisi suhu dan kelembapan pasar yang relatif tinggi (27–32°C dan 60–80%) mendukung perkembangan populasi hama tersebut. Keberadaan hama berpengaruh terhadap penurunan mutu fisik beras, ditunjukkan dengan meningkatnya persentase butir patah, menir, dan kadar air yang melebihi batas standar SNI. Berdasarkan hasil analisis, keberadaan S. oryzae sangat dipengaruhi oleh kondisi penyimpanan dan kadar air beras. Oleh karena itu, diperlukan penerapan sistem penyimpanan yang lebih higienis dan pengawasan mutu di tingkat pedagang untuk menekan populasi hama dan mempertahankan kualitas beras yang beredar di pasar tradisional Kabupaten Serang.

Abstract

This study evaluated the effect of AB Mix concentration on the growth and yield of lettuce (Lactuca sativa L.) varietiesgrown in a Nutrient Film Technique (NFT) hydroponic system. The experiment was conducted from December 2025 to February 2026 at Allisa Farm, Serang, Banten, Indonesia, using a split-plot design with two factors. The main plotconsisted of AB Mix concentrations at 560, 840, and 1000 ppm, while the subplot included three lettuce varieties: Batavia Caipira, Grand Rapids, and Sementel. Data were analyzed by analysis of variance followed by Duncan’s Multiple RangeTest at the 5% level. AB Mix concentration significantly affected several growth and yield parameters. The 1000 ppm treatment produced the highest number of leaves (19.09), leaf greenness (31.60 SPAD units), root length (21.72 cm), and shoot fresh weight (135.67 g), and supported better plant height during the vegetative stage. Variety also had a significanteffect, with Batavia Caipira showing the best performance in number of leaves, leaf greenness, and shoot fresh weight, while Grand Rapids produced the tallest plants. A significant interaction between AB Mix concentration and variety was observed only for leaf area, with the highest value recorded for 1000 ppm AB Mix combined with Batavia Caipira (94.51 cm²).

Abstract

Shallots are one of the horticultural crops with the best chances of being consumed in large quantities in the community. Low shallot output, however, leads to uncertain shallot pricing—soil degradation results from farmers’ widespread use of inorganic fertilizers. Therefore, organic fertilizer that is safe for the environment must be used. This research will investigate the effects of Trichoderma harzianum and cow dung fertilizer on the growth and yield of shallot plants (Allium ascalonicum L.). The research was conducted in the Banten Agricultural Instrument Standard Assessment Center’s Screenhouse from May to July 2024. The study used two variables: the Factorial Randomized Complete Block Design (RCBD). Three repetitions of each therapy resulted in 48 treatment combinations. Cow manure dosages are the first factor: 0 g/polybag, 31.4 g/polybag, 62.8 g/polybag, and 94.2 g/polybag. The second element is Trichoderma harzianum dosage, which may be 0, 4, 7, or 10 g/plant. If a difference is found after a variance analysis at the 5% level, a DMRT is performed at the 5% level. The following attributes were measured: fresh weight, dry weight, bulb weight, number of leaves, bulbs, and bulb diameter. Findings showed that the 94.2 g/polybag dose of cow dung fertilizer affected the quantity of leaves, fresh weight, dry weight, and bulb weight. On leaf number 4 WAP, Trichoderma harzianum (7 g/plant) and cow manure fertilizer (62.8 g/polybag) interacted.

Abstract

Cucumber (Cucumis sativus L.) is a plant that has various advantages, one of which is a relatively short harvest period. This study was conducted to determine the most effective dose of NPK Phonska fertilizer and the optimal concentration of gibberellin growth regulator (GA3) to increase the growth and productivity of cucumber (Cucumis sativus L.) plants. This study was conducted from May to August 2025 at the Puri Serang Hijau, Serang City, Banten. The experiment was designed as a randomized block design with two treatment factors: the dose of NPK Phonska fertilizer (0, 350, 400, and 450 kg/ha) and the concentration of GA3 (0, 150, 175, and 200 ppm). The results showed that a single application of NPK Phonska fertilizer at a dose of 400 kg/ha gave the best effect on the growth and productivity of cucumber. This was reflected in greater plant height and more leaves, compared to other doses. The application of a single GA3 at a concentration of 200 ppm improved plant reproductive characteristics, such as accelerated flowering time. This study highlights the age of flower emergence and harvest age according to the varieties used as research objects.
