Abstract

The concept of urban farming, such as microgreens, as an effort to increase indoor plant cultivation, can be a solution to land problems. This research was carried out to determine the response of providing long periods of LED lighting and different types of planting media on the growth and production of red spinach microgreens (Amaranthus tricolor L.). The method used in this research is an experimental method with a Split Plot Design (Split plot or ) which consists of two factors, namely the length of exposure of the LED lights as the main plot with 4 levels including L1 (14 hours of exposure), L2 (16 hours of exposure), L3 (18 hours of light) and L4 (20 hours of light) and types of planting media as sub plots with 4 levels including M1 (cocopeat), M2 (zeolite), M3 (malang sand) and M4 (husk charcoal) which was carried out with 3 repetitions . The results showed that there was an interaction between alignment time and planting media on the observation parameters of plant height, wet weight, wet crown weight and root length, while the number of leaves was not significantly different. Key-words: long exposure time, planting media, red spinach microgreens INTISARIKonsep urban farming seperti microgreens sebagai salah satu upaya untuk meningkatkan budidaya tanaman dilakukan secara indoor, dapat menjadi salah satu solusi dari permasalahan lahan.

Abstract

This research aims to determine land suitability classes for soybeans using a geographic information system (GIS), limiting factors, and land improvement efforts that can be made to land suitability for soybeans in Karang Tanjung District, Pandeglang Regency. There were several stages in the data collection method, namely the survey stage, field observation, and laboratory analysis. The data collected was analyzed using the matching method and then analyzed descriptively. The research results show that the actual land suitability class for soybean plants is N (not suitable) with factors inhibiting water availability (rainfall). Efforts that can be made to improve non-permanent limiting factors in land suitability for soybeans include carrying out demolition activities during land processing, liming, applying organic material, fertilizing, making terraces, planting parallel to contours, and planting ground cover crops. Keyword: Geographic Information System, Land Suitability, Soybean Plants INTISARI Penelitian ini bertujuan untuk mengetahui kelas kesesuaian lahan untuk tanaman kedelai dengan menggunakan sistem informasi geografis (SIG), faktor pembatas dan upaya perbaikan lahan yang dapat dilakukan terhadap kesesuaian lahan untuk tanaman kedelai di Kecamatan Karang Tanjung Kabupaten Pandeglang. Terdapat beberapa tahapan dalam metode pengumpulan data, yaitu tahap survei, observasi lapangan  dan analisis laboratorium. Data yang dikumpulkan dianalisis dengan metode pencocokan kemudian dianalisis secara deskriptif. Hasil penelitian menunjukkan bahwa kelas kesesuaian lahan aktual untuk tanaman kedelai  adalah N (tidak sesuai) dengan faktor penghambat ketersediaan air (curah hujan). Upaya yang dapat dilakukan untuk memperbaiki faktor pembatas bersifat non permanen kesesuaian lahan untuk tanaman kedelai yaitu melakukan kegiatan pembongkaran pada saat pengolahan lahan, pengapuran, pemberian bahan organik, pemupukan, pembuatan teras, penanaman sejajar kontur dan penanaman tanaman penutup tanah. Kata kunci: Sistem Informasi Geografi, Kesesuaian lahan, Tanaman Kedelai

Abstract

This study aims to determine the effect of various concentrations of leaf fertilizer on red chili (Capsicum annum L.) of the Laju F1 variety cultivation. This research was conducted at the experimental garden Instalasi Penelitian dan Pengkajian Teknologi Pertanian Balai Penelitian Tanaman Sayuran Serpong (IP2TP Balitsa Serpong). The method used in this research was the experimental method of Randomized Block Design with one factor, namely giving various levels of concentration leaf fertilizer consisting of six treatment levels namely 0; 1; 2; 3; 4; and 5 g/l with a total of 5 replication to obtain 30 experimental units. The results showed that leaf fertilizer has a significant effect on the average plant height parameter at 5 weeks after planting (WAP) (53.12 cm); stem diameter 3 WAP (3,99 mm), 4 WAP (6.85 mm), and 5 WAP (8.87 mm); fruit length per plant at 2nd harvest (15.55 cm); and fruit diameter per plant at 1st harvest (9.26 mm) and at 2nd harvest (9.77 mm); fruit weight per plant (1157,54 g); and fruit weight per plot (2673,34 g). The treatment of various concentrations of leaf fertilizers showed no significant differences in the parameters of the amount of fruit per plant.

Abstract

Beneng Taro (Xanthosoma undipes K. Koch) is a local food crop from Gunung Karang, Banten, with high nutritional potential whose productivity is closely related to soil biological conditions. This study evaluated soil fauna abundance and diversity in talas beneng cultivation areas across three elevations: highland (851-858 m asl), midland (590-602 m asl), and lowland (343 m asl). A quantitative exploratory approach was applied using pitfall traps with ten replications per site and composite soil sampling at 0-20 cm depth. Soil chemical properties (pH, C-organic, N-total, and C/N ratio) were analyzed, and diversity was calculated using the Shannon-Wiener index. A total of seven soil fauna orders were recorded, with Hymenoptera dominating all sites. The midland exhibited the highest abundance (67 individuals), while the lowland showed the highest diversity index (H’=1.077 medium category). Variations in abundance and diversity were associated with differences in soil pH, nitrogen availability, and C/N ratio, which influenced decomposition rates and nutrient dynamics. The findings indicate that elevation-related environmental factors significantly shape soil fauna communities and underscore the importance of soil fertility management in supporting sustainable talas beneng cultivation. Keywords: Abundace, Altitude, Beneng taro, Soil Chemical Properties, Soil Fauna.

Abstract

Tomato (Solanum lycopersicum L.) production in Banten has significantly declined due to land constraints and suboptimal cultivation practices, necessitating sustainable alternatives like fermented rice wash water (RWW) and optimal planting media. This study aimed to determine the most effective combination of RWW concentration and growing media composition to enhance tomato growth and yield in polybag cultivation. The research was conducted from November 2025 to March 2026 at Universitas Sultan Ageng Tirtayasa, Banten, using a factorial Randomized Complete Block Design. Factors included RWW concentrations (0, 50, 100, and 150 mL/L) and four media compositions (soil; soil+manure; soil+husk charcoal; and soil+manure+husk charcoal).The results showed that the soil-only medium (B0) produced the best vegetative performance, particularly for plant height and stem diameter. Specifically, the interaction of 100 mL/L RWW and soil (S2B0) yielded the highest plant height of 35.60 cm at 4 weeks after transplanting. Furthermore, a significant interaction was observed in the generative phase, where 50 mL/L RWW combined with soil and rice husk charcoal (S1B2) achieved the highest productivity, reaching a fruit weight of 158.00 g and 11.33 fruits per plant. These findings suggest that integrating 50 mL/L RWW with porous media is the most effective strategy for optimizing tomato yield

Abstract

Superior seed quality is one of the keys to success in growing shallots. The purpose of this research was to analyze the effect of the concentration of biofertilizers and types of planting media on the growth of shallot seed origin of True Shallot Seeds (TSS) in the nursery. This research used a split-plot design consisting of two factors. The first factor is the concentration of biofertilizers, and the second factor is the type of planting medium. The results showed that the application of biofertilizers increased the growth of the shallot seed origin of TSS than without the application of biofertilizers. The application of biofertilizer at 1.5 mL.L-1 water gave the best results regarding the number of leaves per seedling and fresh weight. However, treatment with different concentrations of biofertilizers made no significant difference; treatment with concentrations of 1 mL.L-1 water was more efficient for the growth of shallot seeds. The type of planting media treatment did not significantly affect all parameters observed for the growth of shallot seed origin of TSS. There is an interaction between the concentration of biofertilizers and the type of planting media on the growth of shallot seed origin of TSS, namely the number of leaves aged 5 weeks after seedling, while for other parameters, there is no interaction between the concentration of biofertilizers and the type of planting medium on the growth of shallot seed origin of TSS.
