Abstract

Permasalahan global terkait lahan tercemar akibat aktivitas industri berdampak terhadap penurunan produksi tanaman padi di Sidoarjo. Endapan logam dari limbah industri dapat mengontaminasi lahan tersebut. Maka dari itu solusi yang dapat dilakukan untuk perbaikan lahan sawah dengan pemberian pembenah tanah. Tujuan penelitian untuk mengkaji efisiensi asam humat dan silika untuk meningkatkan N dalam tanah dan serapan nitrogen tanaman padi. Penelitian ini dilaksanakan di Kebun Percobaan Kecamatan Balongpanggang, Kabupaten Gresik. Penelitian ini disusun menurut Rancangan Acak Lengkap (RAL) Faktorial. Faktor pertama dari dosis asam humat dan silika sebanyak 0 kg.ha-1, 10 kg.ha-1, 20 kg.ha-1, dan 30 kg.ha-1 . faktor kedua terdiri dari 3 lokasi yang terindikasi tercemar. Parameter pengamatan dibagi menjadi 3 yaitu analisa sub-sampel tanah, pengamatan pertumbuhan tanaman padi dan serapan nitrogen tanaman padi. Analisi data dianalisis dengan menggunakan keragaman (ANOVA) terhadap sifat kimia tanah dengan uji lanjut BNJ 95%. Hasil dari penelitian menunjukkan aplikasi asam humat silika berpengaruh nyata terhadap kadar nitrogen di dalam tanah dan serapan tanaman padi, tetapi tidak berpengaruh nyata terhadap pertumbuhan padi. Dosis terbaik pemberian asam humat silika pada lahan sawah dekat industri farmasi (L1) dan lahan sawah dekat industri kertas (L3) adalah 30 kg.ha-1 (P3) dengan nilai N sebesar 0,16%, sementara pada lahan sawah dekat industri pakan ternak (L2) dosis terbaik adalah 20 kg.ha-1 (P2) dengan nilai N sebesar 0,19%. Efisiensi serapan tanaman tertinggi yaitu terdapat pada perlakuan pada lahan sawah dekat industri pakan ternak dengan dosis 30 kg.ha-1 yang menghasilkan efisiensi serapan sebesar 52% pada bagian akar, sedangkan efisiensi tertinggi pada bagian daun menghasilkan efisiensi sebesar 64,62% dengan dosis 10 kg.ha-1.

Abstract

Rice husk waste is an abundant agricultural byproduct in Karang Langit Village, Lamongan, but its utilization is still limited, posing a potential environmental problem. This community service program aims to modernize agricultural practices by utilizing rice husk as a hydroponic growing medium to support food security and promote a circular economy. The methods applied include community coordination, carbonization of rice husks, preparation of the hydroponic system, and both theoretical and practical hands-on training. Evaluation results show a significant increase in participants’ knowledge by 32%. A total of 85% of participants successfully prepared a viable rice-husk-based growing medium, and 75% were able to cultivate and harvest leafy vegetables in the trial phase. Additionally, a farmer group was formed and is committed to independently continuing hydroponic practices after the program’s conclusion. These results confirm that utilizing rice husk as a hydroponic medium not only enhances community skills and self-sufficiency but also opens new economic opportunities. This model is recommended for replication in other agricultural areas to support local food security and environmental sustainability.

Abstract

Soil degradation caused by industrial waste in Sidoarjo Regency has led to a decline in agricultural productivity, necessitating soil rehabilitation efforts. This study aimed to evaluate the effectiveness of silica humate as a soil amendment on paddy fields contaminated by industrial waste. The experiments were arranged according to the Factorial Complete Randomized Design, where the first factor: 3 kinds of industrial waste namely the pharmaceutical, livestock feed, and paper industry. Second factor; 5 doses of silica humat (0, 10, 20, 30, and 40 kg/ha). The parameters included soil pH, cation exchange capacity (CEC), total nitrogen (total-N), and available phosphorus (available-P), measured at 14 and 56 days after application (DAA). Results showed that the effectiveness of silica humate varied depending on the type of industrial waste and increased over time. On land contaminated with pharmaceutical waste, silica humate increased CEC from 44.34 to 52.52 cmol(+)/kg and available-P from 27.21 to 36.69 ppm at low doses. Land contaminated with animal feed waste showed the best results at a dose of 20 kg/ha, while land contaminated with paper industry waste required higher doses. These findings suggest that silica humate is promising as a viable soil amendment strategy, though optimal dosage rates must be tailored to specific industrial contamination types for maximum rehabilitation effectiveness.

Abstract

Urban farming activities in Surabaya have continued to grow rapidly since the end of the COVID-19 pandemic in 2022, meeting approximately 20 percent of the city's vegetable needs. The improved skills of various vegetable cultivation groups, including the Barokah Farmers Group in Babat Jerawat Village, Pakal District, have led them to be named "Jawara". Armed with this achievement, they are attempting to expand into seasonal fruit farming using hydroponic technology under the shade of a screen house. On the other hand, Surabaya's hot weather and relatively high humidity are obstacles to implementing hydroponic cultivation systems in screenhouses. Exposure to intense sunlight during the day can increase the temperature of the pipes containing the net pots and nutrient reservoirs to 45°C, thus impacting the temperature of the AB Mix nutrient solution and the physiology of melon plant roots. Armed with experience from research and melon cultivation practices, the community service implementation team conducted a demonstration plot of superior hydroponic melon cultivation in a screenhouse. Based on the findings of the hydroponic installation research on campus, several modifications have been made to the hydroponic installation, including the addition of a cooling layer for the netpots and hydroponic nutrient reservoirs. The added heat insulation layer maintains the temperature of the piping and nutrient reservoir between 30-32°C. This is expected to allow the melon plants to grow normally without environmental stress until harvest, when they yield optimal fruit.
