Abstract

Most fishing vessels in Indonesia use diesel engines as their driving force. Diesel engines are mechanical machines where component contact is unavoidable, so a lubricating system is absolutely necessary to reduce the level of component damage that intersects. The decrease lubricating system capability has an impact on engine damage. The purpose of this study is to identify the causes of damage to the diesel engine lubricating system for fishing vessels, making it easier to make decisions in carrying out maintenance and repairing lubricant systems. The method for identifying each possible failure occurs using a Preliminary Hazard Analysis (PHA) and Fault Tree Analysis (FTA). PHA is a device to identify potential hazards that result in system failure, FTA is a device to identify the causes of system failure. FTA works by determining failures which are referred to as "top events", then the top event identifies the relationship of the factors causing various failure events with fault trees that use simple logic gates "and" and "or". The formation of an FTA can determine the factors causing failure with a minimum cut set. Based on the results of the analysis, there are three main causes of diesel engines failing because the lubricating system is the failure of lubricating system components namely internal leakage (screen lubricant + pressure alarm + manometer + officer), and (lubricating pump + pressure alarm + manometer + officer).

Abstract

Fishing activity by catching gill nets by Pangandaran fishermen is using traditional methods inherited by ancestors especially in determining fishing ground such as seeing the color of water surface, small ripple, fish jump, the presence of foam, and see the existence of birds. Such activities make fishing activities less than optimal because the level of uncertainty is high and will impact on high operational costs such as the use of fuel wasted and trip time becomes longer. Knowledge of fishing zones is essential for fishing activities because by knowing potential fishing areas will result optimal catch and reduced effort. Information about potential fishing areas can be obtained through analysis of the distribution of a-chlorophyll in water. The research was doing from October to November 2017. The research used survey method with 7 experimental fishing activities in Pangandaran Waters. From the results of this activity can known that category distribution of fishing ground catchment area in Pangandaran spread from medium to potential category.

Abstract

Utilization of Gen-set Hibrid Photovoltaik-Diesel (DC-AC Couple Battery-Backup Grid Connecting PV System) is a efforts to minimization operational  cost from Stick held dipnet. This case is caused by diesel fuel which has higher price and rare. This article will discuss about analysis approach as first, calculate impact need of lighting toward rate of catching phototaxis fish. This case use analysis different test (test of t) toward output of optimum catching use 4 underwater lamps which have different of kind. The porpose from this case to analysis genset diesel capacity by usage optimum power of lighting. The method will be used is calculating instrumentation load factor, synchronic factor, and load of genset factor as standart of BKI. Based on monitoring, selected under water lamp E-CDL 45 W is real different (tcalculate3,4355>ttable2,776) which has more optimum catching of fish (6960 Kg) than others. Based on calculating needed daily load capacity 2530 W. It mean the capacity of Genset Hibrid PV array-Diesel 34020 Wh, appropriate with Samate water condition which has low and high temperature (27,1o C and 31,8o C) needed 15 PV-modul @200 W (the voltage and electric current source of PV array 100 Vdc and 31,6 A), bank battery 14 units @200 AH/12 V which has output voltage is 24 Vdc, 2 units charge controller (@current input 15 A), 1 unit inverter (voltage input 24 Vdc/output 240 Vac and 3000W), battery charger (input 240 Vac/output 24 Vdc), and MCB (standby load : single phase 220 Vac) 15 A Busbar 45 A. Ecomonic analysis use Life Cycle Cost (LCC) method toward genset (diesel and Hibrid PV array-diesel). From the calculating, nominal of LCC genset Hibrid PV array-Diesel (Rp.173.421.297,-) lower or cheaper than LCC genset diesel (Rp.223.715.493,-). The net from this case is Rp.50.294.196,- which got for 20 years instrumentations usage. The last discuss about calculating distance between stick held dipnet and area which can reached to outside lighting lamp (E-CDL 50 W) at height 5 meters toward surface of sea water is 235 m2.
