Abstract

Injector is an important component in the diesel engine fuel injection system. This study aims to obtain the results of the in-line type injection pump calibration in the equation of the fuel volume of a 4 cylinder diesel motor. The research was conducted by making simple calibration equipment. Experiments were carried out for 200-300 rpm, 350-450 rpm and 550-600 rpm experimental apparatus rotation speed. Measurements are made for the volume of fuel using a measuring cup. Injection pump calibration is done by loosening the lock on the sleeve then sliding the sleeve to the left or right on each plunger to get fuel volume similarity. The results of data collection before calibration showed the volume of fuel was 26 ml, 30 ml, 30 ml, and 28 ml. Keywords: calibration, injecton pump, in-line, diesel engine

Abstract

Handling heat energy in the industrial world is very necessary. Heat exchangers have a fluid system that can be designed and developed using pipes. Heat transfer in a heat exchanger is a support for the performance of a heat exchanger to make it better. In this study, a heat exchanger was tested by placing a variety of barriers on the field of heat transfer flow and the addition of variations in the flow rate on the heat pipe. This test uses a aliran inch water flow pipe and a 2.5 inch iron tube pipe and a barrier material using aluminum. Based on the test results obtained a graph of varying heat transfer increases in each barrier. Differences in barrier variations and variations in water discharge greatly affect the value of heat transfer results. The purpose of this study was to look for the effectiveness and effect of adding a flow barrier to the performance of heat transfer in a heat exchanger. Keywords: Heat Exchanger, Effectiveness of Heat Transfer Heat

Abstract

Abstrak Suhu perairan berperan mengendalikan kondisi ekosistem perairan. Peningkatan suhu menyebabkan peningkatan dekomposisi bahan organic oleh mikroba. Perubahan suhu permukaan dapat berpengaruh terhadap proses fisik, kimia dan biologi di perairan tersebut. Suhu air yang baik adalah antara 25℃-30℃, pada derah yang suhu air nya relatif rendah atau pun tinggi perlu pemanas atau pendingin untuk mencapai suhu yang relatif stabil. Pada sensor suhu yan berbahan dasar logam, semakin tinggi suhu maka nilai resistansi akan semakin besar. Salah satu sistem pendingin yang biasa digunakan oleh masyarakat adalah lemari es. Sebagian besar lemari es menggunakan sistem refrigeraasi kompresi uap (SRKU) yang memiliki coefficient of performance (COP) yang tinggi dibandingkan sistem pendingin lainnya. Suhu air memang harus dipertahankan dalam hal budidaya jika suhu naik ikan akan stress sedangkan ada beberapa cara untuk mempertahankan suhu air bisa dengan TEC termoelektric control atau sistem kompresi dengan sistem pendinginan kompresor dengan freon. Penelitian ini bertujuan untuk mendesain inovasi pengkondisian suhu air pada proses pemijahan kepiting bakau. Kata kunci: suhu, sistem pendingin, kepiting
