Abstract

Slow Release Fertilizer (controlled release fertilizer) is a type of fertilizer with the release of nutrients that can be adjusted to the needs of a plant. Fertilizer that is coated with a semi-permeable material will not dissolve easily in water so that the fertilizer that has been coated is not easily washed off or evaporated. One of the semipermeable materials is chitosan, chitosan is later added to coat a nutrient which will be applied to the soil to absorb and keep the nutrients available and not wasted into the environment. Purpose of this study was to determine the effectiveness of chitosan-coated NPK fertilizer on nitrogen release and interactions with mustard greens. Method used Chitosan-coated NPK fertilizer was given according to the dosage set for each treatment and the results showed that the release of nitrogen elements from chitosan-coated urea fertilizer into the soil proved that nutrients were released more slowly, and conclusions obtained from research There is a real interaction in the treatment of chitosan against Nitrogen in plants. The suggestion from the researcher is based on the need to analyze other parameters to support the completeness of the research on the use of chitosan.Key-words: Chitosan, Slowrelease, PlantINTISARIRendahnya kandungan unsur N dapat menghambat pertumbuhan suatu tanaman dan menyebabkan pertumbuhan tanaman menjadi kerdil, jumlah anakan atau percabangan menjadi sedikit. Oleh sebab itu maka diperlukan penambahan bahan yang dapat mengontrol pelepasan nitrogen pada pupuk sebagai upaya meningkatkan ketersediaan Nitrogen bagi tanaman. Penelitian ini dilaksanakan pada tanggal 05 Desember 2022 hingga tanggal 20 Maret 2023 bertempat di Lahan Green House Institut Teknologi Sepuluh November Surabaya. Penelitian ini menggunakan Rancangan Acak Lengkap 2 faktorial. Faktorial pertama yaitu grade NPK dan factorial kedua dosis penggunaan kitosan. Hasil penelitian menunjukkan bahwa penggunaan kitosan mampu memperlambat proses pelepasan unsur hara pada tanah, berdasarkan hasil sidik ragam terdapat interaksi nyata pada Grade pupuk NPK 20 – 16 – 16 dengan kombinasi kitosan 0,2 gram memberikan hasil yang nyata pada melambatnya unsur hara Nitrogen dibandingkan dengan perlakuan lainnya. Kata kunci: Kitosan, Pelepasan, Nitrogen

Abstract

Gunung Anyar District in Surabaya focuses on agropolitan development to encourage regional economic growth, especially in agribusiness. Micro, Small, and Medium Enterprises (MSMEs) are important in improving the economy, reducing unemployment, and improving welfare. However, MSMEs face challenges with branding, digital marketing, and environmental impact. The community service program by UPN Veteran East Java aims to support the development of MSMEs through digitalization, product branding, and product diversification. The program also discusses environmental issues, including waste management and Urban Farming. Collaboration between local governments, MSMEs, and the community is essential for the success of this program. The program aims to overcome barriers such as low sales turnover and limited market access, strengthen the position of MSMEs in a competitive market, and become an example of sustainable business practices. The Lecturer Team conducts continuous socialization and assistance related to MSME skills in implementing digital marketing, training and mentoring "e-brilliant MSMEs" and maintaining cleanliness and preservation of the surrounding environment to reduce carbon footprint, increase green open space, and meet food needs through urban farming.

Abstract

This study aimed to evaluate the effect of humic-silica application on P availability and P uptake by corn in land contaminated with heavy metals. The experiment was arranged in a Completely Randomized Design (CRD) with two treatment factors. The first factor consisted of three industrial locations: the pharmaceutical industry, the animal feed industry, and the paper industry. The second factor consisted of four levels of humic-silica application (in kg/ha): 0, 10, 20, and 30. Observations were made at the age of 14 and 70 days after planting (DAP). The parameters included soil organic carbon, Cation Exchange Capacity (CEC), soil P-available, and total P uptake by corn plants. Results showed that the humic-silica application at 20 kg/ha had a significant effect on P-available and P uptake by corn plants. This positive effect was consistent in the three industrial locations, both in 14 DAP and 70 DAP observations. These findings indicate that the use of humic-silica at 20 kg/ha has potential to reduce the negative impacts of heavy metal pollution on the availability of plant nutrients in industrial lands. This study provides insight into strategies for managing industrially contaminated lands to increase agricultural productivity, especially in terms of increasing the availability and absorption of phosphorus by corn plants.

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.
