Abstract

Development Region V consists of Marpoyan Damai District, TampanDistrict, and Payung Sekaki District, with an area of 140,96 km2 and a population of 510,107 people. In 2016, the waste generated from this development area settlement was 1,049,179 l/day. The development region V with high data on population and waste generation per day is the biggest contributor to waste and if the management of the waste is not optimal that will cause the existence of illegal dumping increased.The purpose of this study is to map and analyze geophysical, anthropogenic and community characteristics. This research was conducted with a direct survey methodto the study area with GPS Garmin 60CSx type, then mapped using GIS software, ArcMap 10.1. In the V development region, 33 locations of illegal dumping werefound. There were no illegal dumping found at a distance of ≤ 15 m from the river. In the distance parameters of arterial and local roads, the existence of illegal dumpingis generally located at a distance of <5 m or at the shoulder of road, that can caused by the accessibility or of the community to dispose of garbage to that location easily.For the land type, mostly the community will be waste disposal on the main road. On the road type parameters Illegal dumping, commonly were found on arterial roadsbecause the service center for transporting garbage is generally on arterial roads. The insufficient number of legal dumping causes the number of illegal dumping increased. The number of illegal dumping increases with the high population density.The level of education and knowledge will influence attitudes and behavior of waste management, because low levels of education and lack of knowledge will improve unhealthy attitudes and behavior. The number of illegal dumping increased with theincrease in the number of respondents with the type of work of traders.Keyword: Geographic Information System(GIS), Illegal Dumping, ArcMap, Mapping of Illegal Dumping

Abstract

The palm oil industry is currently experiencing very rapid development which is marked by an increase in CPO production. The main solid waste produced by the palm oil processing industry is Empty Fruit Bunch (EFB) which is 22-23%. The composting process is one of the processing methods that can be done on EFB waste, however, the composting process requires a long time. Therefore, it is important to do a breakthrough to speed up the processing time. In this study, composting can be accelerated by adding mixed cultures and POME as a source of nutrition. The purpose of this study was to determine the effect of variations in POME addition on windrow aerob composting of EFB on the quality of N, P, K. In composting process takes place with variations by adding POME 0%, 20%, 30%, and 40%. The results of the study showed that the effect of POME 40% addition gave the best results as indicated by the highest N, P, K content of 2.41%, 2.29%, 2.56%, temperature 33.61OC, pH 6.84, and water content 49.4%, and compost produced meets SNI 19-7030-2004 compost quality standards. Thus, the performance of composting with the best result is with the addition of 40% POME with 25 days composting time. Utilization of oil palm empty fruit bunches is one of the solutions to sustainable environmental pollution control.Key Word : Composting Process, Empty Fruit Bunch, NPK, Palm Oil Mill Effluent (POME), Windrow.

Abstract

Bioethanol (C2H5OH) is an organic chemical widely used as a solvent. It is also applied in producing germicides, beverages, antifreeze, fuel, and depressants as an intermediate in producing other chemical substances. Generally, bioethanol is generated from the fermentation of glucose (sugar) accompanied by a distillation process. This study aimed to optimize bioethanol production against variations in pre-treatment and solvent concentrations through enzyme hydrolysis and fermentation of oil palm empty fruit bunches. The pre-treatment is an important stage in the conversion process of lignocellulosic biomass, as it eliminates lignin, reduces the crystallinity of the cellulose, and increases the porosity of the substance, thereby facilitating the hydrolysis process and glucose fermentation. The process was carried out with different concentrations of acid, base, and organolsov solvents, after that, it was hydrolyzed using cellulase enzymes for 24 hours and fermented using Saccharomyces Cerevisiae yeast for 5 days. Furthermore, the bioethanol produced was separated through a rotary vacuum evaporator at 180 rpm and a temperature of 78 °C. The highest ethanol content produced was 7.8% with 4% NaOH and 90 minutes of pre-treatment residence time.

Abstract

Peningkatan jumlah penduduk Desa Batu Belah setiap tahunnya, akan mempengaruhi produksi sampah yang dihasilkan. Hingga saat ini, pengelolaan sampah organik dan anorganik di tingkat desa masih menjadi tantangan. Penanganan sampah ditingkat rumah tangga dan desa umumnya dengan cara dibakar. Hasil pembakaran berupa asap tentunya dapat menimbulkan polusi udara yang berdampak negatif terhadap Kesehatan. Minimnya edukasi dalam pengelolaan sampah menyebabkan Sebagian besar jumlah sampah hanya menjadi timbunan di Tempat Pembuangan akhir (TPA). Oleh karena itu diperlukan pemberdayaan masyarakat dalam bentuk edukasi, sosialisasi, dan pelatihan keterampilan akan hal tersebut. Salah satunya pengolahan sampah organik dengan memanfaatkan media budidaya maggot BSF (Black Soldier Fly). Limbah organik dapat dimanfaatkan sebagai pakan maggot. Kegiatan pengabdian secara keseluruhan dapat dikatakan baik dan berhasil, sebanyak 35 peserta hadir untuk  mengikuti acara ini. Hasil dari kegiatan ini sudah tercapai yaitu  menambah pengetahuan dan keterampilan masyarakat tentang pemanfaatan limbah organik seperti sampah sayuran dan buah menggunakan maggot BSF yang  selanjutnya akan dimanfaatkan oleh masyarakat sebagai bahan alternatif pakan ternak. Dilihat dari ketercapaian tujuan pelatihan (100%), ketercapaian target materi yang telah direncanakan (100%), dan kemampuan peserta dalam penguasaan materi (75%).
