Abstract

Siltation of the river, ditches, reservoirs in urban areas is a problem because it causes flooding. The government annually undertakes dredging of the precipitate for the flow of water to flow smoothly. Soil sedimentary water potential to be utilized as a medium of planting in the development of urban agriculture. The research was conducted by survey method in water area of Surabaya. The sample was taken using random method of choosing, that is choosing condition of place environment and soil condition which is possible for planting medium. Soil sediment samples were observed for pH, color,structure, texture, organic matter content, Nitrogen (N-total), K2O and P2O5. The result of research showed that all of the textured sedimentary soil content of clay was about 89,87-92,14%, organic material was about 5,96-7,60%, total N was about 0,09-0,13%, K2O was about 0,88-1,12%, and P2O5 was about 2,08-2,44%. The color of soil was grayish-black. The mud deposits of the housing sewer were the most crumbling and the most consumptive reservoir was sludge. Sewage soil sludge is potentially used as a planting medium in the development of urban agriculture. Keywords: Planting Media, Urban Agriculture, Soil Sedimentary.

Abstract

Composting serves as a pivotal strategy in waste management, alleviating the burden on final disposal sites while simultaneously providing valuable fertilizer for urban agriculture. This study aims to delineate the intricacies of the composting process and elucidate the characteristics of compost derived from recycling centers/compost houses in Surabaya City, Indonesia. Employing a qualitative descriptive approach, this research scrutinized the composting process by delving into the origins of raw materials, procedural stages, and the chemical composition of the resultant compost. The composting materials encompassed household waste, market refuse, and fall foliage. Notably, composting occurred within an open aerobic system devoid of bio-activators. Chemical analysis revealed: C/N ratio (17.10 - 19.60), C-total (17.65% - 18.10%), N-total (0.95% - 1.12%), P2O5 (0.35% - 0.51%), K2O (0.39% - 0.41%), Cu (1.65 ppm - 2.01 ppm), Pb (2.05 ppm - 3.11 ppm), Cd (0.11 ppm - 0.24 ppm), and Zn (1.02 ppm - 1.14 ppm). Physically, the compost manifested as a dark brown substance, exhibiting a soil-like softness attributable to grinding, with temperatures oscillating between 41.90 to 55.00°C. Visually, the compost appeared mature and primed for utilization based on color and texture criteria; however, indicators such as C/N ratio and temperature suggest an immature state rendering the compost unsuitable for immediate planting. To ensure optimal maturity conducive to plant growth, it is recommended that users store the compost for a minimum of one month before application, thereby fostering its maturation process.

Abstract

The problem of accumulating organic waste can be solved by converting it into compost and can be used to strengthen food security in urban areas. The purpose of this research is to find a solution to the problem of urban organic waste burden into an economically valuable resource by processing it into compost, studying the effect of urban organic waste compost on the growth and yield of vegetable plants (shallots), and providing a fertile and affordable planting medium, reducing dependence on conventional fertilizers that must be imported from outside the city. Research on the application of compost produced from a compost house for shallot plants with 4 treatments: pure soil planting medium, soil planting medium plus leaf compost, soil planting medium plus young coconut fiber compost, and soil planting medium plus rain tree leaves. The study used a randomized block design with seven replications. The results of the study were that the best growth and yield of shallot plants were obtained from plants planted in soil media without being mixed with compost, while the worst were from plants planted in soil media with fresh rain tree leaf compost. The conclusion of the study was that the compost used was not yet mature because the composting process was only 28-35 days, or with rain tree leaves without a composting process. The use of immature compost or organic material that has not fully decomposed will actually have a negative impact on plants. Plants and microbes compete for nutrients or plants can be poisoned by compounds produced by the composting process (such as ammonium compounds). The implication of this research is that compost utilization will have a positive impact when the compost is fully mature. Compost producers, such as compost houses or recycling centers (PDU) in Surabaya, should release mature compost or socialize to the public that compost produced from compost houses needs to be incubated for at least 30 days before it can be used for urban farming activities.
Analisa Keputusan Petani dalam Penggunaan Pestisida untuk Pengendalian Hama dan Penyakit Tanaman Tomat (Solanum lycopersicum): Analysis of Farmers' Decisions on Pesticide Use to Control Pests and Diseases of Tomato Plants (Solanum lycopersicum) Haryanta, Dwi; Susilo, Achmadi; Prayogo, Bagas Tri

Abstract

Penggunaan pestisida yang kurang tepat oleh petani merupakan isu kritis yang dipengaruhi oleh faktor-faktor psikologis, perilaku, sosial ekonomi, dan regulasi. Tujuan penelitian adalah untuk menganalisis proses pengambilan keputusan petani dalam menggunakan pestisida untuk mengendalikan hama dan penyakit tanaman tomat. Penelitian kuantitatif diskriptif dengan kuesioner disusun berdasarkan lima dimensi persepsi petani tentang keberadaan hama dan penyakit tanaman tomat dan cara pengendaliannya meliputi: (1) Persepsi petani terhadap keberadaan hama dan penyakit (X1), (2) Persepsi petani terhadap terjadinya kerusakan pada tanaman (X2), (3) Persepsi petani terhadap terhadap Teknik pengendalian hama dan penyakit (X3), (4) Persepsi petani terhadap penggunaan pestisida (X4), dan (5) Persepsi petani terhadap efek negatif pestisida (Y). Temuan penelitian adalah para petani tomat mengetahui adanya hama dan penyakit yang menyebabkan kerusakan pada tanaman tomat. Oleh karena itu diperlukan tindakan pengendalian dan yang paling praktis adalah dengan menggunakan pestisida. Para petani mengetahui dan menyadari bahwa penggunaan pestisida berdampak negatif terhadap lingkungan dan kesehatan konsumen. Kesimpulan penelitian adalah petani tomat selalu menggunakan pestisida (insektisida dan fungisida) untuk mengendalikan hama dan penyakit agar mendapatkan hasil panen yang dapat dijual di pasar. Keselamatan konsumen dan kelestarian lingkungan belum menjadi menjadi pertimbangan dalam penggunaan pestisida. Perlu mendapatkan perhatian bagi penyusun kebijakan khususnya dari Dinas Pertanian untuk mensosialisasikan dan menyelenggarakan pelatihan kepada petani akan Teknik pengendalian hama yang aman dan berkelanjutan. Penggunaan pestisida seharusnya menjadi langkah terakhir dalam pengendalian hama dan penyakit.
