Abstract

This research wa aimed to know the implementation of profit share system and wage system that are applied on gill net fishery business at Trisik Beach, Kulon Progo Regency. It was to know BEP level that is considered as limitation in determining the implementation of profit share system and to compare between wage system and profit share system that is earned by fisherman and ship’s owner with the UMR on Yogyakarta The reseach was conducted on Trisik Beach, banaran, Galur Sub district, Kulon Progo Regency in the early of August until the early of November 2017. The method that were used in this research included case study method, drawing sample, data collecting and data analyzing. The result of this reseach showed that ship’s crew earned Rp.2.284.000,- per mount and Rp.10.420,- per hour, ship’s captain earned Rp.6.602.000,- per month and Rp.300.420,- per hour. But for the company staf, they earned Rp.1.144.812,- per month and Rp. 38.160,- per day and also Rp.4.770,- per hour. By those way, it was more profitable using profit share system on Gill Net Monofilament Fihery business at Trisik Beach, Kulon Progo Regency compare to UMR 2017 at that Region, is Rp.1.373.600,--

Abstract

The Marine Conservation Area (MCA) of the Marine Tourism Park of Pieh and the Surrounding Islands, consists of Bando Island, Pieh Island, Air Island, Toran Island and Pandan Island with covering of ​​39,900 Ha wide. Geographically Pieh Island is at coordinates 00⁰ 45’ 10" - 01⁰ 03’ 08" LS / 99⁰ 59’ 36" - 100⁰ 59’ 28" BT, and administratively falls within the Padang Pariaman District, Pariaman City and Padang City. The research was carried out in the waters of the core zone of the MCA Toran Island. Pieh Island at coordinates 01⁰ 01 '55 "- 01⁰ 03' 02" LS / 100⁰ 09 '36 "- 100⁰ 11' 02" BT. With the LIT (Line Intercept Transect) method using a 50 meters long transect with the rope drawn parallel / horizontally. stretch of coral reefs at six points of the observation station. The results shown the percentage of live coral cover ranged from 20.94% - 35.00% (bad - moderate category) with an average value of 25.93% (medium category). The diversity index value (H ') ranges from 1.76 - 3.16 (low - high category), with an average value of 2.44 (medium category). The uniformity index (E ') value is generally classified as a high category (stable community) ranging from 0.77 - 1.00 with an average value of 0.88 (medium category). While the dominance index (C ') does not show the extreme conditions of one species against the other species, this is indicated by the dominance index value of less than 0.5 (low category), which ranges from 0.05 - 0.42 with an average value 0.24 (low category).

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

This study aims as follows: 1) to determine the status of Ecosystems Approach of Fisheries Management (EAFM) in the domain of fish resources for commodities in South Sorong Regency, West Papua Province. The method used in this research is survey method, interview and interview. The results of the study in this study, for the Standard CpUE indicator, Composition of Catching Species and Collapse Range of Fish Resources are still in good status. While the indicators that need to be prioritized for improvement in sustainable management because it has a moderate to bad status, namely Fish Size Trends, Proportion of Yuwana (Juvenile) Fish that have been used and ETP Species. The results of the study show that the management of banana commodities (Penaeus merguiensis) is in good condition with green flag modeling and a mean value of 3.

Abstract

The red rainbow fish ( Glossolepsis incisus Weber ) is one of Indonesia tropical ornamental freshwater fish which has economical high value. But growth rate is to slow cause the fish rarely available in the market. The purpose of this research was to find out the effect of vitamins C on spesific growth rate of this fish. The method used was in the experimental methods with 5 treatments and 2 replications of a 2 cm and 6 cm. Dosage of vitamins C used was 0 mg/kg of feed, 500 mg/kg of feed, 1000 mg /kg of feed, 1500 mg/ kg of feed and 2000 mg/kg of feed. The result showed that the added of vitamins C is high significant of SGR, FCR and significant pH and DO on the media but does not significant whit SR and temperatur. The result showed that the vitamins C with SGR and FCR is quadratic and the best dose to obtain whit added of vtamins C 1666 mg/kg of feed on the size 2 cm and dose 1111 mg/kg of feed on the size 6 cm. The increase of SGR dependent by the increasing dosage of vitamins C as weell as FCR, but if vitamins C excessive and not according to needs will be a reduce SGR and FCR.
