Abstract

Title: Planting Sengon by Afforestation in Sukoharjo Village, Tirtomoyo District, Wonogiri Regency. This service activities aimed at introduce the vegetative conservation methods for minimized erosion and conserve land resources by afforestation with sengon. This activity was in collaboration with two partners, namely: (1) "Ngudi Mulyo" and (2) "Ngudi Tani I" Farmers Groups located in Sukoharjo Village, Tirtomoyo, Wonogiri. The business fields developed by the two partners were dry land agriculture. The problem that the land was hilly and rolling and more degradated due to high erosion. In this program, farmers will be introduced with vegetative method to reduced erosion and preserved land resources by reforestation with sengon. Activities included: preparation (coordination), procurement of seeds, fertilizers, tools and socialization on vegetative soil conservation method to reduced erosion and preserve land resources by reforestation with sengon. After the socialization and giving of sengon seeds, monitoring was carried out related to planting and maintenance. The results of the program  showed the enthusiasm of the community in participating both in socialization and planting of sengon seeds for reforestation

Abstract

Program IbM ini bekerjasama dengan dua mitra, yaitu: (1) UKM Peternakan Puyuh “Agribird ”, dan (2) Kelompok Tani “Mekar Tani”. Mitra (1) dan Mitra (2) berlokasi di dukuh Gunung Wijil, Desa Ngringo, Kec. Jaten, Kab. Karanganyar, Jawa Tengah dengan jarak tempuh sekitar ± 3,5 km. Permasalahan utama yang dihadapi oleh mitra usaha „Agribird‟ adalah produksi limbah ternak puyuh yang sangat tinggi, yaitu sekitar 300 kg limbah per hari. Produksi limbahnya sangat tinggi per hari, maka kemampuan produksi limbah jauh melibihi dari kemampuan untuk memanfaatkannya. Bila limbah ini dibuang langsung ke badan sungai terdekat, maka akan mencemari air sungai, sedangkan bila limbah akan diubah menjadi pupuk organik, maka diperlukan teknologi pembuatan pupuk organik. Permasalahan Mitra 2 (Mekar Tani) : lahan yang tiap tahunnya ditanami padi selama 2 kali musim tanam. Musim tanam yang ke-3 diberokan (tidak ditanami), termasuk sawah-sawah petani yang ada di sekitarnya.Solusi yang ditawarkan untuk mengatasi permasalahan utama yang dihadapi mitra (1) adalah teknologi pembuatan pupuk organik yang dapat digunakan sebagai pupuk organik yang sangat bermutu yang dapat digunakan sebagai pupuk organik bagi usaha budidaya tanaman jagung pada mitra (2) yang dapat menambah masa tanam.Kegiatan ini merupakan penerapan Biofilmed Fertilizer yang telah diujikan pada penelitian Pengembangan Biofilmed Biofertilizer Beragens Hayati dari Konsorsia Rhizobiota Bawang Merah (RG Strategis Nasional 2015-2016) serta Teknologi Pengelolaan Limbah untuk Pakan dan Pupuk pada Sistem Pertanian Terpadu Berbasis Perikanan, Peternakan Puyuh dan Sayur Organik (RISTEK - Insinas 2014-2015).

Abstract

Alfisols have low fertility, so fertilization is carried out to increase soil fertility and support the growth of maize plants. The continuous use of inorganic fertilizers in high quantities can cause land degradation, so it is necessary to reduce the amount by adding other fertilizers, such as organic fertilizers, as well as the relatively high price of inorganic fertilizers. This research was aimed to examine the potential of organic fertilizers in replacing inorganic fertilizers. The experimental design was a completely randomized block design with nine combination treatments of organic and inorganic fertilizers with three replications. The results showed fertilizer treatment ½ NPK + 1 PO affected and increased levels of organic C, CEC, base saturation, total N, and available P in Alfisols and maize yield. However, it did not significantly affect pH, base saturation and available S in Alfisols. The chemical properties of the soil had increased values ​​of 48%, 9.01%, 61.3%, and 134.5%, respectively. The treatment of ½ NPK + 1 PO  increased maize productivity by 47.76% compared to the control with the productivity of 12.7 t ha-1, which the results were not significantly different from standard NPK. Thus, the application of 10 t ha-1 of organic fertilizer has the potential to replace ½ doses of inorganic fertilizer.
