Abstract

Abstract. Garbage is an environmental pollutant material that is always there at all times. To reduce environmental pollution, efforts are made to burn waste by using a tool in the form of an incinerator. An important aspect in designing an incinerator is to pay attention to the safety factor for the user when it is operated. The insulator in an incinerator has a very important role. In an effort to reduce the conduction of heat generated during combustion, the incinerator is coated with glass wool as an inner coating that is able to inhibit the heat that comes out when the tool is used. The method used in this study is to compare the temperature measurement of the inner wall of the SS400 Steel plate before being coated with glasswool, the measurement of the temperature of the combustion chamber of the incinerator and the measurement of the temperature of the outer wall of Zinc Galvalume. After the installation of glass wool in the incinerator, measurements were made in the combustion chamber, the results obtained reached ±700-800 oC. The results of this study indicate the use of glasswool can reduce the heat resistance that comes out of the SS400 steel plate wall but increases the temperature in the combustion chamber. The mass of waste and fuel can affect the combustion temperature that occurs. The output of organic waste is in the form of ash which can be used as fertilizer.

Abstract

Abstrak. Mesin parut kelapa ini merupakan salah satu produk mesin dari hasil teknologi yang berfungsi sebagai alat menghancurkan daging buah kelapa menjadi butiran-butiran kecil dengan tujuan untuk memperoleh parutan dan santan yang terkandung di daging buah kelapa. Dari mesin yang sudah ada, dengan kapasitas tinggi dan harga listrik tinggi. Dari sini penulis membuat mesin ini dirancang untuk mempermudah aktivitas indutri rumahan kecil yang digunakan secara praktis, ringkas dan hemat listrik. Dengan mempertimbangkan mesin motor listrik yang ringkas dengan daya rendah 125 watt. Dapat diharapkan menjawab semua kebutuhan masyarakat untuk membuat mesin parut kelapa dengan kapasitas kecil. Awal memulai perancangan pertama-tama pengambilan data atau gambar, untuk selanjutnya studi lapangan, studi literatur, verifikasi data, olah data, analisis data, dan pembuatan mesin. Hasil dari rancang bangun adalah mesin pemarut kelapa dengan satu parutan dan bisa digunakan untuk memarut singkong dan kentang, untuk membuat makanan manusia dalam kehidupan sehari-hari, mesin parut kelapa ini lebih efisien, ringkas dan hemat daya listrik. Perancangan mesin parut kelapa ini menggunakan motor listrik dengan transmisi puli dan v belt, dengan sistem parutan menggunakan sistem pemarut di ruang parut. Sistem kerja alat ini menggunakan pemarut saja. Hasil dari kerja parutan kelapa ini didapatkan rata-rata proses parutan dengan kapasitas 7.5 kg/ jam.

Abstract

Ceramics are widely used by people in industries for various purposes, for example to make cups and tiles. Currently ceramics are widely used in various industrial raw materials. Ceramics are used as materials for making spark plugs, electrical insulators, and raw materials for printing tools. The ceramics industry is energy intensive in utilizing electrical energy. The amount of energy absorption affects the amount of costs that must be incurred by companies for energy consumption. To reduce costs used by ceramic companies during production, the use of energy is a way to increase the efficiency of the tunnel kiln. Therefore, based on these problems, research was carried out to analyze the data resulting from measurements of the large flow rate of heat transfer by conduction in the thickness of the wall, the amount of heat loss lost by convection on the outside of the wall, and the amount of loss in production costs incurred due to heat loss. This aims to obtain a solution that saves electrical energy used in the production of ceramics. So it was obtained that the highest conduction was in the top firing zone of the core from burning red bricks with heat dissipation reaching 829.73 Watts. Meanwhile, the heat lost at a distance of 50 cm and at a distance of 100 cm is the top firing zone which has the greatest heat loss of up to 0.1 MW compared to the other zones. The preheating zone reaches 5 kW and the cooling zone reaches 16 kW.
