Abstract

Biomass briquette stove is a cooking tool that is still widely used by the people of the interior of South Sulawesi. Even in urban areas, it is not uncommon to find their use because of the ease of obtaining briquettes and its relatively good efficiency. This study aims to determine the best performance of a biomass stove from three types of clay material stove shapes in different configurations of geothermal variations. The three variations of the geometric shape of the stove are cylindrical, rectangular and hexagonal using biomass material from coconut shell charcoal in the shape of a honeycomb with an inner diameter of 15 mm and an outer diameter of 65 mm and a height of 45 mm. The uniqueness of this stove is the addition of a sleeve diameter of 180mm in the stove's combustion chamber as heat insulation so that the combustion process in the combustion chamber can be more perfect. The test results show that the presence of a flat surface on the stove wall will accelerate heat loss compared to the cylindrical surface. This is in line with the results which show that the highest rate of heat loss occurs in a rectangular shape, then a six-square shape, and the last is a cylindrical shape. Furthermore, it can be concluded that the cylindrical stove is the superior of the two in terms of flame temperature, ability to boil water and thermal efficiency of 798°C, 30 liters and 73.66%, respectively.

Abstract

Kota Tarakan merupakan kota dengan pertumbuhan penduduk yang cukup tinggi di Provinsi Kalimantan Utara. oleh karena itu, kegiatan pembangunan juga meningkat dan kualitas lingkungan akan menurun akibat pencemaran limbah seperti limbah plastik rumah tangga. Tujuan penelitian ini adalah merancang bangun mesin pencacah limbah plastik yang diintegrasikan dengan sistem rotation control untuk tiga jenis sampah plastik yakni Polypropylene, Polyethylene Terephthalate, dan High-Density Polyethylene. Hasil penelitian ini menunjukkan bahwa mesin pencacah plastik yang telah dibangun terdiri dari frame mesin yang dibuat dari bahan besi siku dengan dimensi 40 x 40 x 3 mm, pisau pencacah bermata 2 dan cover yang terbuat dari bahan ST37, hopper dari bahan plat besi tebal 1,2 mm, motor listrik 1 HP, sistem transmisi puli dengan perbandingan 1:4 dan gearbox dengan perbandingan 1;15, dan sistem rotation control. Kapasitas mesin yang dihasilkan untuk ketiga jenis sampah plastik sebesar 7,2; 7,14; dan 6,6 kg/jam, masing-masing.
