Abstract

Kendal Regency is one of the areas in northern Central Java which has potential resources for mud crabs (Scylla spp.). Communities in Kendal Regency use folding traps and gill nets to catch mud crabs (Scylla spp.). The catching activities of mud crabs in Bandengan waters Kendal are carried out all the time, without providing a recovery period on the ecosystem cycle at the fishing location. This study aims to analyze the technical and financial feasibility of catching mud crabs using folding traps and gill nets. The method used in this research is descriptive method with a survey approach. Data collection methods used are direct observation, interviews, literature and documentation. The analytical method used is break even point analysis, R/C ratio, B/C ratio, and payback period. The results showed that folding traps and gill nets are feasible to run because folding traps have a BEP value of IDR 43,286 (<sale price); production BEP value of 333 kg/year (<production/year); value of R/C ratio 1.38 (> 1); the B/C ratio value is 0.38 (> 0); PP value for 1 year 7 months while gill net has a BEP value of IDR 41,480 (<sale price); production BEP value of 313 kg/year (<production/year); value of R/C ratio 1.45 (> 1); the B/C ratio value is 0.45 (> 0); PP value for 1 year 6 month. Gill nets is more feasible to run than folding traps because it has a higher R/C ratio and B/C ratio than folding traps. Then the BEP and PP values is lower if it as compared with folding traps.

Abstract

Pekalongan fishing port is a fishing base for purse seiners of small pelagic fish in Central Java. Range of fishing fleets Gross Tonnage is 69 to 125 GT. Purse seine was dominant fishing gear with total percentage 84% from the total fishing gear at Pekalongan fishing port in 2014. The main target of purse seine is shoaling pelagic fish. The objectives of this research were to analyze the catch composition and Catch Per Unit Effort (CPUE) of purse seiners at Pekalongan Fishing Port. The method of this research used survey method. Data analysis with quantitative descriptive method. Analysis conducted on the catch composition and Catch Per Unit Effort of purse seiners. Data to analyze the catch composition was secondary data of purse seiners catches volume in 2016 from January until December. And to calculate the CPUE used secondary data of fishing trips and total production of purse seiners from 2008 to 2016. Variations of dominant type of captured i.e. Shortfin scad, Indian scad, Bali Lemuru, and Indian mackerel. Every month there was different of species dominance caught by the gear ranged from 7 to 11 species. The percentage of each species was Shortfin scad (Decapterus macrosoma) caught dominantly  in January, October, November and December. Indian scad (Decapterus russelli) reached the highest percentage in June, July, August and September. Bali Lemuru (Sardinella lemuru) mostly caught in February, April and May. While Indian mackerel (Rastrelliger kanagurta) caught with highest percentage in March (40%).  Location of fishing ground was in Indonesia Fisheries Mangement Area with code  712 and 713. The annual average CPUE of purse seine in Pekalongan Fishing Port was 18,712 kg or 18.7 metric tonnes per trip for each fleet. This result shows that the productivity of purse seiners was quite low compared with the size of fishing fleet Gross Tonnage 69 up to 125 tons.

Abstract

Karawang Regency has a fishing port with the status of a Coastal Fishing Port. Fishing Ports provide services to fishermen as users of the facilities available at the port. One kind of service is administrative service at the Fishing Port, this service is related to fishing operational activities. The purposes of this study were to analyze the fishermen's satisfaction level with fishing port services and to find out what services are considered important by fishermen. This study analyzed the Customer Satisfaction Index (CSI) and Importance Performance Analysis (IPA) methods to measure fishermen's satisfaction. Based on the results of the study indicate that the assessment of satisfaction with services at the Ciparage Coastal Fishing Port is classified in the satisfied category. This is shown by the value of the Fisher Satisfaction Index, which is 76.565%. The service that has the highest value is the attributes of the facilities at the Fish Auction Place (TPI) and the attitude of the administration officers at the port. The conclusion of this condition should be maintained by the port, the suggestion from this research is that there is a need for an expansion of the pier facilities at the port so that it can accommodate a number of vessels to lean.

Abstract

Indonesia is listed as the world's most used cooking oil (UCO) producing country. Biodiesel from UCO blends is claimed to have lower carbon emissions. A regional scale of sustainable UCO collection and processing ecosystem needs to be established to enhance the role of local authorities in the circular economy. Central Java has the potential for ecosystem planning for UCO management with a circular economy approach. Central Java Province has a total UCO potential of 36,217 kilo liters and can be used for biodiesel potential of 27,094 kilo liters per year. If it is assumed that the processing cost is IDR 9,000.00/liter. The biodiesel production cost for a year is IDR 243.86 trillion/year. Total revenue assumption of IDR 298.04 trillion/year (base price IDR 11,000.00/liter). The profit gain is IDR 54 trillion/year or IDR 4.5 billion/month. The B/C ratio of biodiesel processing is 0.22 and is considered profitable. This program is called Turn Oil On (TOOn). Keywords: Used cooking oil, Biodiesel, Circular economy, Central Java
