Abstract

EFB (Empty Palm Oil Bunches) is waste that is produced in large quantities by palm oil mills in Indonesia. About 22-23% OPEFB is produced from every ton of FFB (Fresh Fruit Bunches), or around 220-230 kg of OPEFB. Unfortunately, most of the palm oil mills and communities in Indonesia have not fully utilized this waste. The problem in this research is how to use empty oil palm bunches as organic fertilizer for the people in Simandiangin Village, Kab. South Labuhanbatu. The research method uses qualitative methods by going directly to the field and using interview techniques. The results of research in the village of Simandiangin, Kab. Labuhanbatu Selatan found that the empty fruit bunches were bought from the factory using a truck and piled into the area closest to the tree to be fertilized. Within a year the owners of oil palm plantations in this area buy about 2 times a year. Then the owner of the garden employs several people to directly arrange them in a circle to the oil palm plants. In the application of empty fruit bunches, approximately 20-30 empty fruit bunches for oil palm plantations are given. The conclusion in this study is that the use of empty fruit bunches as organic fertilizer has considerable potential to help increase soil fertility and agricultural productivity. Oil Palm Empty Bunches (EFB) can be used as mulch, namely the covering layer of soil around the plants. The purpose of mulch is to reduce water evaporation, retain soil moisture, and inhibit weed growth. In addition, empty bunches will also decompose over time and provide nutrients to the plants.

Abstract

Introduction: Waste is the result of residue or waste from a production activity, such as the cassava chips industry which produces solid and liquid waste in its production activities. Both types of waste will have a negative impact if the waste is not treated. The waste from processed cassava which often has a negative impact is liquid waste. The aim of this research is to analyze the processing of solid waste and liquid waste generated from the cassava chips industry and their impact on the environment. Method: This research is a qualitative research. Data obtained from direct observation and interviews. The research subjects are the cassava chip industry owners and the longest-serving workers in the industry. The research instruments consisted of researchers, interview question texts, stationery, and voice recorders. Presentation of data descriptively based on the results as they are. Result: Some of the waste generated is processed and some is not processed. Solid waste that is not processed is waste cassava peels and cassava cobs. The sediment waste from cassava soaking water is processed into mocaf flour. Meanwhile, the liquid waste produced is not processed. Conclusion: The cassava chips industry studied only produces mocaf flour as a new product from the utilization of the waste produced. The impact of cassava chips liquid waste is to contaminate water and soil, and stagnant wastewater becomes a breeding ground for disease vectors.
