Abstract

The problem with this boiler is that the steam produced is not continuous, meaning that at a pressure of 1 bar, thesteam lasts for approximately 2 minutes, and the heating process of this fire-tube boiler is also prolonged, taking around 95minutes from the start until reaching a temperature of 100°C. This results in the need for more used oil as fuel. Some initialanalyses to solve these issues include increasing the heating surface area of the boiler or the combustion chamber by adding watertubes and using wood as the fuel. The objective of this research is to analyze the heating time, steam retention time, wood f uelconsumption, and efficiency before and after the modification with the addition of water tubes. The method used is experiment al.The tests conducted before modification showed a heating time of 45 minutes, and with the addition of water tubes, the heatingtime was reduced to 36 minutes. The steam retention time before modification was 4 minutes, while with the addition of watertubes, it increased to 4 minutes and 42 seconds. The total wood fuel consumption for the fire-tube boiler to reach an operatingpressure of 3 bar required 33.2 kg of wood, and after the addition of water tubes, the total consumption to reach 3 bar wasreduced to 27 kg of wood. The efficiency of the fire-tube boiler before modification at 1 bar pressure was 66.6%, at 2 barpressure 59.3%, and at 3 bar pressure 51.6%. After adding water tubes to the fire-tube boiler, the efficiency increased, with theefficiency at 1 bar pressure being 74.5%, at 2 bar pressure 68.8%, and at 3 bar pressure 62.9%. This indicates that the addition ofwater tubes can improve the boiler's efficiency.

Abstract

One of the typical Indonesian food products is tofu, tofu is a food that is always produced by the community which has become a hereditary culture, especially those produced by craftsmen in Rokan Hilir Regency. In the process of making tofu in Rokan Hilir Regency still uses a manual method of stirring, one of the stages in the process of making tofu is boiling soybean porridge. In addition to determining the quality of the product, the stirring process is also a stage that requires a lot of energy and time. In making tofu during the stirring process, it must always be stirred so that the mixture is evenly distributed, then so that there is no crust at the bottom. In addition, according to the partners, the stirring process greatly affects the tofu produced. Therefore the author makes a tofu stirring machine tool with a capacity of 100 liters / process which is able to stir the tofu with a time of 20 minutes / process. using an electric motor type 0.5 hp and a speed of 1450 pn. The design of this tool can be useful and help workers in the process of stirring tofu to make it faster and more efficient.Typical Keywords: Tofu Kneading Machine, Tofu or Soybean Processing, Typical Indonesia Food

Abstract

Pengelolaan rumput di lingkungan SMK Negeri 1 Bengkalis dilakukan untuk memperindah   tanaman   lanskap   maupun   sarana   luar   ruangan.   Penerapan pengelolaan rumput yang baik didaerah Sekolah dapat meningkatkan kualitas estetika bangunan dan lingkungan secara keseluruhan. Alat yang digunakan untuk memotong rumput ditaman di kampus semuanya mengunakan mesin rumput tipe gendong. Penggunaan pemotong rumput manual (tipe gendong) tidak efisien dan juga mengandung resiko kecelakaan. hal ini memungkinkan resiko yang tinggi jika terjadi kelalaian ketika mengoperasikan alat tersebut yang akan berakibat fatal bagi operator, selain itu banyak waktu dan tenaga yang tersita hanya utuk mengoperasikannya. Untuk itu perlu dirancang suatu alat pemotong rumput yang efisien dan dapat mengurangi resiko kecelakaan dalam menggunakan peralatan tersebut dengan memodofikasi mesin rumput tipe gendong menjadi tipe dorong dengan roda untuk mengurangi resiko kecelakaan kerja seperti terkena paku, batu dan pisau serta mengurangi kelelehaan operator terutama tukang kebun.
