Abstract

The coral reef ecosystem has role as feeding and nursery ground for indicator reef fishes. Coral reef ecosystems in recent years has decline in function, globally the area of coral reefs has decline about 11%. This study aims to analyze the correlation between the condition of life coral reef with the abundance of indicators reef fish. This research was conducted in the waters of Mandrajaya (Ciletuh Geopark) with 5 stations. The method used in this research is Line Intercept Transect (LIT) and Underwater Visual Census (UVC). Data observed were the percentage of live coral and dead coral, as well as the number of indicator reef fish found. Results show that the percentage value of life coral is 51.17% dominated by the CF (Coral Foliose) category, this value shows that the condition of living coral cover is included in the good category. The obtained Mortality Index is worth 0.43 (low), this value is obtained from the ratio of life coral and dead coral. A total number of indicators reef fish is 31 individuals / 1750m² from four species, dominated by Chaetodon octofasciatus (12 individuals). Correlation between life coral cover and abundance of indicators reef fish was positive and had a sufficient relationship on both variables (r = 0.58) with a determinant coefficient of 48%.

Abstract

The highest fish production in Labuan Coastal Fishing Port (LCFP) is mackerel tuna which reached 41,953 ton (22.1%) of total production. Mackerel tuna is economical and perishable commodity. Therefore, it requires a good marketing chain to maintain its quality. The purpose of this research is to determine the marketing chain of mackerel tuna landed at LCFP; determine the marketing margins of each marketing agent; and analyze the quality of mackerel tuna from unloading ship to the consumer. This research was conducted in March-April 2019 at LCFP. This study used the survey method. While the methods used for quality testing of tuna are sensory (visual observations) or by organoleptic tests by parameters in the form of eye conditions, gills, meat and odor texture of fresh fish standards using a score sheet based on BSN. Checking the quality of fish is done at every marketing chain. Data analysis was carried out descriptively. The result show that there are four types of marketing chains in LCFP. The highest marketing margin obtained by outside trades (IDR 5,000 or 20%) on the fourth channel and the lowest margin sales obtained by main collectors on the second and third channels (IDR 2,000 or 8%). The longer the marketing chain, the lower the quality of mackerel tuna.

Abstract

Tangerang Regency experienced very high coastal dynamic processes, caused by natural factors (abrasion and accretion) and anthropoligical factor (reclamation). This study aims to determine the latest condition of the Tangerang regency coastal dynamics as well as Pantai Indah Kapuk (PIK) area of Jakarta by using analysis of Google Earth images. The land area changing was calculated through visual interpretation approached by using on-screen digitizing. The applications used are Google Earth Pro 7.1.5.1557 and ArcGIS 10.2. Out of a total of 23 coastal villages, abrasion occurred in almost 20 villages. The highest abrasion phenomenon occurred in Kohod village, Pakuhaji district, with a land area lost of 71.55 ha during the 2004-2019 period. The highest accretion process occured at the estuary of the Cisadane river which was in Tanjungburung village, Teluknaga district. While the highest reclamation activity taken place in the village of Kosambi Timur with the total area of the reclaiming beach reached 56.54 ha. In both villages, Kosambi Timur and Dadap, District of Kosambi, the reclamation did not only occur at sea, but also on land. The area of fishponds that has been reclaimed and converted into the New Urban Zone of Pantura is about 936,78 ha. This is the largest fishpond conversion into a city ever happened in Indonesia. As a comparison, the conversion of aquaculture land to urban land had occurred previously in PIK Jakarta with the area of converted ponds around 678 ha.

Abstract

The development of the fisheries industry in Morotai Island District faces major challenges in investment climate recently. Those investment is influenced by fisheries resources, infrastructure, markets and institutions. This paper aims to describe the fishery industry in Morotai Island District, analyze the concept of the fishery industry model, and formulate a strategy for economic integration. Primary data was taken using a structured questionnaire through interviews with respondents and focused group discussions (FGD). The primary information is supplemented by secondary data obtained from district statistical data, research reports, and related scientific publications. Data were analyzed using four methods, namely: descriptive analysis; Analysis of Strengthen, Weakness, Opportunity and Threat (SWOT); Quantitative Strategic Planning Matrix (QSPM) analysis; and MIC-MAC analysis. The results from the analysis show the integrated marine and fisheries center (SKPT) policy implementation has had a positive effect on the fisheries industry development in Morotai Island. There are four main influence aspects: (1) marine and fisheries resources (SDKP) management; (2) economic and business development; (3) community development; and (4) regulatory and synergies. The strategy of economic integration is focused on the implementation of the fisheries industry model as the production and export base for fresh tuna.
