Abstract

Kedungkandang District is one of the fastest growing areas in Malang City and become a urban area. The implication this development is dcreasing of urban open space area by 1 - 2% per year, and followed by increased surface flow during rain. Infiltration well is one of the efficient rainwater utilization to reduce run-off. In Kedungkandang district three are different soil types which affects the permeability coefficient value for determination the dimension of infiltration well. This study aimed to determine the dimension of infiltration wells suitable for application individual infiltration wells for housing type 36, 45, 54, 70, 90 and 110.  In order to determine dimension of infiltration wells would be used, there were some analysis done: hydrology and soil permeability coefficient. The conclusion from this research was the bigger the house size, it would need a bigger dimension of infiltration well as well. From the three types of soil in Kedungkandang, the houses in alluvial fan ground type and tuff volcanic soil require a smaller size of infiltration wells than the houses located in Buring volcano mountain sediments.Key words: infiltration well, run-off

Abstract

Skipjack tuna is one of the fishery commodities which has high economy value due to the high demand and high prices in the export commodities. The purpose of this research is to identify and analyze the potential resources of tuna and also determine its alternative management in Prigi Fishing Port (Pelabuhan Perikanan Nusantara Prigi). This research was carried out at Prigi Fishing Port, Trenggalek, East Java from February to April 2016. The method used in this research was descriptive method. The data analysis methods were the standardization of the fishing gear, the analysis of catch per unit effort (CPUE), total allowable catch (TAC), and the skipjack tuna fishery management concept at Prigi Fishing Port. The fishing gears which were used to catch skipjack tuna are payang seine, trolling line and purse seine. However, the standard fishing gear used to catch the skipjack tuna was trolling line. CPUE analysis results were obtained from the CPUEstd average value in 2005-2014 as many as 4.79 kg/unit. The allowed amount of the skipjack tuna fish farming was 3,028 tons/year and the result in 2014 was 460.82 tons, means that the skipjack tuna utilization was still under fishing. Meanwhile, the fishing attempt of 224 units was exceeding because it has passed the optimum limit of fishing by 102 units. The results of the study recommended several policies of the skipjack tuna management which are: (1) the amount limitations of the fish farming; (2) the management of the fishing attempts; and (3) the regulation of the fish farming closing season.Keywords: fisheries management, skipjack tuna (Katsuwonus pelamis), Prigi Fishing Port, TAC

Abstract

The purpose of this study was to analysis about the composition of the catch, the selectivity of fishing gear and fishing gear level of friendliness to the environment. The data collection is done by experimental fishing.  Selectivity analysis applied by  Shannon diversity index and Simpson dominance index. Analysis of scoring was used to rate the friendliness of fishing gear on the environment. The main target of the catch composition (33.93%) and the by catch (66.07%) of the catch species diversity index was 2,16 to 2,78 (high diversity index; the selectivity of fishing gear is low). Dominance index was 0,36 to 0,50 (did not happen dominance species catches). The total value of the scoring is based on the criteria of degree of friendliness of fishing gear on the environment is the 26 included in the category of less environmentally friendly fishing gear. The catch is dominated by small fish. If it lasts for a long time and continuously, it can adversely affect the conservation of fish resources. It should be a mechanism for management systems such as open and close an area to fishing operations or modifications to fishing gear mechanism which can reduce the yield of bycatch and small ones.Keywords: composition, diversity, dominance and environmentally friendly, selectivity
