IbM DESA SUNGAI RENGAS KALIMANTAN BARAT DALAM PEMELIHARAAN KUALITAS LAHAN BERBASIS PADI MELALUI PEMANFAATAN BIOCHAR ASAL LIMBAH PANEN

Abstract

Sungai Rengas Village, Sungai Kakap District, Kubu Raya Regency of West Kalimantan, is a region that most of the population as rice farmers. However, when viewed from the average production of existing rice, it only reaches 2 tons of ha-1 (Masulili, et al., 2010), resulting in low farmer income. This low production occurs because the farmers' rice fields are tidal land with sulphate soil type. This type of soil has plant growth constraints in the form of low pH, high Al and Fe content so that nutrient deficiency. Masulili research results, et al. (2010) through the cost of grants Dikti rice harvest waste processed into biochar can improve soil sulphate soil properties and can increase rice production up to 4-5 tons ha-1. In this regard, IBM is aimed at assisting farmer groups in Sungai Rengas Village whose main job is to grow rice farmers in tidal land in order to increase rice production, which in turn is expected to increase income, so that it is economically independent. In order to realize the goal to be achieved, has been done activities of IBM Village Rengas River consists of: 1) counseling about the utilization of biochar waste harvest as a soil enhancer. 2) training the production of biochar from rice harvesting waste using pyrolysis tools. 3) make a demonstration plot of rice plant in tidal rice field. The end result of this activity is the farmers can understand and apply the utilization of biochar waste rice harvest as soil enhancers so that rice production is increased and sustainable.
