Abstract

The objective of this research was to estimate and analyze the availability of Angel fish (Pomacanthus sp.) based on the coral diversity conditions in the Spermonde waters of Pangkep Regency, South Sulawesi. The research method was based on parallel sampling of fish abundance (visual census) and coral cover percentage (Point Intercept Transect) at the study sites, namely Liukang Tumppabiring and Liukang Tangaya waters. The results showed that Liukang Tuppabiring had a fish abundance of 0.00005 individuals per square meter with a standing stock of 138 individuals, while Liukang Tangaya had a fish abundance of 0.005 individuals per square meter with a standing stock of 35,121 individuals. The abundance of Angel fish did not correlate positively with live coral cover, but its presence was influenced by the structural growth forms of the coral, namely branching, submassive, and massive coral in crevices. The production status of Angel fish in the Spermonde waters has exceeded the maximum sustainable yield (MSY). Therefore, additional fishing efforts would decrease the production of Angel fish. This indicates that the Angel fish has been overfished, which can affect its supply. In addition, the inverted curved supply curve indicates a decreasing supply, even with increasing fish prices, as it is suspected that the stock is decreasing.

Abstract

Vessels used for purse seine fishing gear operations in South Sulawesi are made of teak wood (Tectona grandis), spinach with a length of 13 – 25 m, a width of 3.30 – 5.87 m and a height of 1 – 1.8 m. Based on the classification of durability and strength of wooden ships, types of teak and spinach are classified as durable class I and strong class II. Good wood for ship building is one that has a durable class I – II and a strong class I – II (Wibowo 1981 in Marlin, 2008). This means that vessels operating purse seine fishing gear in South Sulawesi are well used because they have relatively large durability and strength. Purse seine vessels in this area have a tonnage between 10 – 35 GT. GT calculation based on Director General of PERLA No, PY.67/1/16-02. The main engine used consists of two units of Yanmar brand, Mitsubishi and Yun chai with a power of 20, 27 or 30 PK. In addition, it is also equipped with a 15 PK Jian Dong brand roller machine

Abstract

Procurement of organic fertilizers is one of the efforts that can be made to restore soil organic matter to increase the production value of the agricultural sector in Jember Regency. Issues about the environment and low soil organic nutrient content also occur in Jember District, especially in Kalisat District, which causes the importance of applying organic fertilizers. The importance of using organic fertilizers requires the participation of farmer groups to be more empowered in producing and using organic fertilizers. The purpose of this study was to analyze the needs and constraints faced to develop a strategy for developing a farmer group empowerment program in the use of organic fertilizers in the Kalisat subdistrict, regency Jember. This research is classified as a qualitative research which aims to analyze the key factors in the farmer group empowerment program. The results showed that in the elements of program needs there were two needs which were key factors, namely organic farming production facilities and local government policies. In the element of constraint there are two key obstacles namely the low knowledge of farmers and the limitations of organic fertilizer processing tools and machines. The resulting strategy is in the form of: 1) Addition of organic farming production facilities. 2) Alignment of local government policies by adding programs to promote the use of organic fertilizers in Jember Regency in the main program of Jember Mandiri. 3) Increase farmer's knowledge related to the manufacture of organic fertilizers through counseling.

Abstract

This study aims to determine the types of ectoparasites found in the thallus of cultivated seaweed Kappaphycus alvarezii and their effect on their growth. The research will be conducted in the seaweed cultivation area of Mandalle Village, Pangkajene Islands Regency. The determination of research stations was carried out purposively (purposive sampling) for three representative aquaculture stations. This is so that it can represent or describe the condition of the waters of Mandalle Village. The cultivation method used in this study was the long line method as used by residents around the study site. Maintenance construction as a sampling unit at each station point, in the form of a 25-meter long rope span of 10 ropes with a distance between the ropes of 1 m. Each stretch rope contains 100-120 seedling clumps with a distance of 20 cm between the straps. Seaweed seeds with an initial weight of 50-70 grams, tied to clump ropes. Planting of seeds is carried out at a depth of 30 cm from the surface of the water. The cultivation construction distance is installed as far as 700-1000 m from the beach. Observation of growth is done by measuring the weight of each clump or the overall weight of each clump of each span rope, at the end of each maintenance cycle. The data obtained for 45 days is then calculated using the growth formula. Seaweed samples for observation of ectoparasites were taken at 3 (three) points of the cultivation area for each bundle of seaweed. The entire surface of the sample thallus was observed with the naked eye and the loop. The results of this study indicated that all observation stations on the South, North and West coasts were dominated by barnacle ectoparasites, followed by green mussels and worms with a total percentage of 90%. While the absolute growth between all stations is relatively the same.

Abstract

Vannamei shrimp is a species of shrimp that is frequently cultivated using conventional methods. This is because vannamei crustaceans have favorable prospects and profits. Traditional Vannamei shrimp cultivation has great development potential, but preventing parasites and diseases that originate in the pond water when cultivating shrimp is impossible. The incidence of disease is closely correlated with parameters of water quality. Pathogenic microorganisms, specifically the Vibrio sp. bacteria, are responsible for one of the prevalent maladies affecting vannamei shrimp farms. Vibrio sp. bacteria produces vibriosis, the clinical symptoms of brownish-red gills, a crimson uropod and abdominal telson, and a sluggish swimming speed. This study aimed to determine the correlation between Vibrio sp. bacteria content and water quality parameters in conventional vannamei shrimp (Lithopenaeus vannamei) cultivation. This study employed exploratory methods and purposive sampling for its sampling. Isolation of microbes using selective media containing TCBSA. The colony abundance of Vibrio sp. bacteria was calculated using the Total Plate Count method. The results showed no significant correlation between the quality of pond water and the abundance of Vibrio sp. bacteria colonies in the traditional system of vannamei shrimp (Lithopenaeus vannamei) cultivation, with a correlation value of > 0.05.
