Abstract

Live coral cover at Sempu Nature Reserve was decrease from 50% in 2006 to 36% in 2013. Adverse human activities such as: over-fishing, recreational activities, waste disposal, deforestation, reef mining and deforestation were suggested to be main factors for declining coral reef at this area. Restoration is defined as the act of returning an ecosystem, as nearly as possible, to its original condition. Coral on Sendang Biru laid on northern area of Sempu Island. Coral garden was establish in the end of 2013. Aim of this research was to know the growth (wide, number of branches, growth rate) of staghorn coral that was transplanted on steel frame at coral garden in different depth. Staghorn coral were tied on doom shaped steel in 6 m depth. The result showed that the average of increasing staghorn coral's area was 56. 91 cm2, number of branch increase was 55 and growth rate was 5.23 cm2/month respectively. Increase of depth will influence to decrease of sunlight intensity in water will be affected on calcification rate of coral. GR of staghorn coral in Sempu was higher than other area.

Abstract

Batu-Malang Government area is one of central production of orange fruit production in East Java. At dry season, the orange plant produce low production level, because there is no available enough water inside the soil. From this facts, it needs effort to increase the orange production especially to facing the dry season, through a new technology engineering and construction of sprinkle irrigation system to increase orange production especially at dry season. Average of irrigation water necessary per days at the treatment of water shower period indicated that the treatment of four times a week reach 20,202 liter as highest value and the treatment of once a week reach 13,000 liter as lowest value. At the bud crown not found obvious differences between factors with the treatment of T1R3 have highest inclination with 175 number of flowers. The treatment of T1R3 indicated 359.667 as highest result and T4R3 indicated 233.667 as lowest result. The treatment of T1R3 indicated 658 as highest result and the control treatment indicated 426.333 as lowest result. The treatment of T1R3 produced 1032.667 as highest result and the control treatment produced 404 as lowest result.

Abstract

Environmental pollution could directly reduce water quality for shrimp cultivation. This study aims to determine how the environmental quality, shrimp population and genetic characteristics of shrimp that live in polluted waters in shrimp ponds in East Java associated with WSSV disease that often attacks on cultivated shrimp. The method used was a descriptive exploratory. Data collection was collected by observation and interview with farmers on disease history. Water was sampled for water quality study and characterize its suitability for shrimp cultivations. Shrimps were also sampled for morphological and genetical study for its susceptibility of WSSV. All samples were taken every week during shrimp cultivation in Malang ans Gresik. Morphological study using scoring method to determine the disease stages on shrimp, while for genetical study using specific primer for ICP11 for WSSV detection, since ICP 11 is expressed when WSSV infection is occur. Samples were taken from 2 shrimp ponds in South Malang and Gresik.The overall water quality is good, except for NO2 and TOM in both seawater shrimp ponds which higher than the freshwater/estuary shrimp ponds. Light infections of WSSV were detected in all seawater ponds both in morphology and genetics. However, in the freshwater/estuary pond only shrimps from freshwater/estuary Gresik which showing light WSSV infection genetically, but not in the morphological signs. Early disease detection is important to control the disease spread.

Abstract

The nutrient content in Banyuwangi coastal environment mostly caused by human activities along the coastal area of Bali strait especially in Banyuwangi surrounding areas. The change of organic element content in waters will directly affect plankton community structure and the aquatic trophic level. The aimed of this research were to analyze the plankton community structure, and to observe the quality of aquatic and determine Bali Strait especially Banyuwangi coastal area trophic level. This research was done in October 2015 at Banyuwangi coastal area. Methods used in this research was descriptive with seawater sampling for water quality analysis of several parameter such as nitrates (NO3), phosphates (PO4), TOM (Total Organic Matter) and Chlorophyll-a, meanwhile other parameters were, temperature, pH, Dissolved Oxygen dan salinity from three different depth of three different stations, coastal area of Bangsring, Tandjung Wangi and Muncar. The results for water quality parameters showed that Bangsring coastal area was the most  healthy waters compared to Bangsring and Muncar. Meanwhile, there were tendency that the concentration mostly high in the surface and decrease along with the deeper depth. This condition presumed caused by the ARLINDO current that passed through Bali strait. Phytoplankton identified and calculated consisted of 3 division, namely Chlorophyta, Chrysophyta, and Cyanophyta with total density ranges between 4-2888 ind/ml. The value of diversity index phytoplankton (H’) ranges between 0,3-0,7. Based on the result it can be concluded that Banyuwangi coastal areas were at throphic level of  oligotrophic tended to mesotrophic in northern part and eutrophic especially in Muncar. Thus, it was suggested for the Government to prevent this area becoming more polluted in the future.

Abstract

One of the main problem of inland waterways fisheries is the transportation of fish from ponds to fish market during low tide trough inland waterways with 0.6m water depth.The boat is experiences grounding due to water depth of the river is not sufficient for the fishing boat to carry fish at it’s maximum2 tones capacity or experience dead freight . This condition forces fisherman to wait until the high tide from the sea, this delay causes the quality of the fish is decreasing.Besides the problem dead freight  problem the existing vessel is causes environmental problem such as erosion of the river bank due to wake wash. The other important issue is the increases of fuel price and it’s scarcity.  This paper presents the results of comparison of existing monohull fishing boat and two other alternativecatamaran designs. The catamaran design alternatives are is ordinary catamaran and flat side catamaran.  Both of the catamaran fishing boat design shows that the catamaran boat with 0.5m draft is able to carry more than 2 tonnes payload during low tide water depth.  The CFD simulation results shows that flat side catamaran resistance is more than 17.7% lower compared to ordinary catamaran and 44% lower compared to monohull. It means that the consumption of flat side catamaran is lowest compared to two other type of hull design. The flat side catamaran also produces lowest wake wash compared to o two other design. The low wake wash means more friendly to environment.
