Abstract

Organic hydroponic cultivation systems require substitute nutrients other than inorganic fertilizers as a source of plant nutrients. Catfish cultivation waste is one of the potentials that can be used as hydroponic nutrients. This study aimed to find out the concentration of Liquid Organic Fertilizer (LOF) from fish cultivation waste as a substitute for commercial inorganic nutrients on the growth of pakcoy (Brassica rapa L.). This research was carried out in 2 stages, namely the manufacture of LOF from catfish culture waste and experiments using LOF as hydroponic nutrients. The results of this study showed that the increase in LOF nutrient content in anaerobic fermentation was higher than in aerobic fermentation. The use of LOF as a hydroponic nutrient, based on the parameters of plant height, number of leaves, SPAD value, root weight, crown weight, and dry weight obtained a smaller value that was significantly different compared to the inorganic nutrient treatment of AB mix. LOF concentration of 20%, both fermented aerobically and anaerobically, gave better growth when compared to higher concentration treatments. The nutrient content in LOF is difficult to adjust to the needs of hydroponic pakcoy, so that it will have a toxic impact on macro nutrients on the other hand, it also provides a response to micro nutrient deficiency.

Abstract

The use of household waste in the form of rice washing water, pineapple skin waste, and leftover rice as liquid organic fertilizer (LOF) has the potential to create a good growing medium so as to increase plant growth. Brazilian Spinach (Alternanthera sissoo) is a leafy vegetable that has the potential to diversify vegetable consumption in urban areas where it is expected to grow well in tight spaces, particularly under shading. This study aimed to find out the effects of applying liquid organic fertilizer made of household waste and the shading on the growth of the Brazilian spinach plant. The study used a split plot design with a main plot consisted of 0%, 50% and 70% shading, while subplot consisted of LOF washing water (20 ml/l), pineapple peel waste (30 ml/l) and leftover rice (50ml/l). Each treatment was repeated 3 (three) times. The results of the study showed that the SPAD value of Brazilian spinach under shading treatment and LOF treatment of rice washing water linearly continued to increase until 8 (eight) weeks after planting. Regarding the vegetative growth of Brazilian spinach, the 0% shading treatment was the best treatment in terms of increasing the non-edible leaf fresh weight and root dry weight. Meanwhile, the LOF had an insignificant effect on all treatments. In conclusion, Brazilian spinach can grow more optimally in no-shade conditions.

Abstract

The 3-in-1 vegetable-fish cultivation is an innovative cultivation system that integrates floating and climbing vegetable cultivation with fish culture. This cultivation is a solution to the problem of narrow land in urban areas for vegetable-fish cultivation to create: a) Fish farming in a concrete pool at the bottom position, b) Shade-tolerant vegetables cultivated using a floating culture system, and c) Climbing vegetables on a dedicated netted-frames as high as 2 meters above the pool. The dimensions of the pool correspond to the available land. The floating raft was constructed using 69 units of 1.5 L plastic bottles as floaters, assembled into a raft with a surface area of 2 m2. The buoyancy capacity of the raft is 120 kg. The raft has been patented with Granted patent No. IDP 000065141. The community service activities are a) Open demonstrations for 3-in-1 vegetable-fish farming installations; b) Socialization and assistance to communities interested in implementing it; and c) Collection of data and information for evaluation and publication materials. Static demonstration activities during one cycle of cultivation and socialization to three potential community groups, namely: a) Urban communities as the primary target; b) Journalists for more enlarging coverage of the dissemination; and c) Agricultural students for the learning process. Urban communities can adopt the dissemination of land optimization through 3-in-1 vegetable-fish cultivation on urban land. Community interest in this cultivation system innovation is outstanding, as represented by the community's enthusiasm for this program.

Abstract

Cassava (Manihot esculenta Crantz) leaves are widely utilized as a leafy vegetable due to their high protein and bioactive compound content. However, information regarding suitable planting materials and planting media composition for optimizing cassava leaf production is still limited. This study aimed to determine the appropriate planting material and planting media composition to improve the growth and yield of cassava leaf shoots. The experiment was conducted from July-August 2024 at the Experimental Field, Faculty of Agriculture, Universitas Sriwijaya. This study used a factorial Randomized Block Design consisting of two factors: planting material (three levels: upper stem, middle stem, and lower stem) and planting media composition (three levels: soil, soil + cattle manure, and soil + goat manure). Each treatment combination was replicated 3 times, and each experimental unit consisted of 3 plants, resulting in 9 treatment combinations × 3 replications × 3 plants per unit, for a total of 81 plants in the experiment. The results showed that the use of middle-stem cuttings combined with soil + cattle manure resulted in higher sprout growth, number of leaves, SPAD index, and leaf-shoot harvest compared to other treatments. Regular leaf shoot pruning increases the number of edible leaf shoots. The selection of planting material with the right composition of planting medium can sustainably increase the productivity of leafy vegetables in cassava.

Abstract

Lahan gambut memiliki peran penting dalam menjaga keseimbangan ekosistem sekaligus menjadi sumber penghidupan masyarakat. Namun, pengelolaan yang kurang tepat menyebabkan penurunan produktivitas serta meningkatnya risiko kebakaran dan degradasi lingkungan. Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan kapasitas petani melalui penerapan model Living Lab Agrosilvofishery di Desa Perigi, Kabupaten Ogan Komering Ilir. Metode yang digunakan meliputi penyuluhan, pelatihan, pendampingan, pembelajaran lapangan (field learning), serta kolaborasi antara Universitas Sriwijaya, Yonsei University, pemerintah daerah, dan kelompok tani. Tahapan kegiatan meliputi persiapan kerja sama, pelaksanaan pembelajaran bersama masyarakat, perancangan solusi secara kolaboratif, serta evaluasi kegiatan. Hasil kegiatan menunjukkan adanya peningkatan pemahaman masyarakat mengenai pengelolaan gambut berkelanjutan, meningkatnya partisipasi petani dalam penerapan sistem agrosilvofishery, serta terbentuknya jejaring kolaborasi antara perguruan tinggi, pemerintah, dan masyarakat. Model Living Lab mampu menjadi media pembelajaran bersama yang mengintegrasikan pengetahuan lokal dengan ilmu pengetahuan sehingga mendukung keberlanjutan pengelolaan lahan gambut.
