Batik Lobster (Panulirus longipes femoristriga) is a potential commodity with limited information, especially on its cultivation aspects. Salinity is one of the cultivation factors affecting the body’s metabolism through the osmoregulation mechanism. The research aims to identify the impact of salinity on the gonad. It was conducted from September 2019 to January 2020 in Mata Shrimp Seeds Center, Kendari City, Southeast Sulawesi. The Batik Lobster (P. l. femoristriga) studied weighed 237±50 grams, with carapace length and width of 7.9 ±0.74 cm and 4.76±0.49 cm, and total lobster under testing of 64 lobsters. The research had different treatments, such as 28, 31, and 34⁰/ₒₒ salinity. The study discovered that the gonadosomatic index of the male lobster (0.44±0.27%) was lower than the female lobster (0.47±0.15%). As for the histological appearance of the lobster, the first and second gonadosomatic indexes were dominated by the oogonia and previtellogenic oocyte stages. It contrasts with the third and fourth gonadosomatic indexes, which were dominant in the mature stage. However, on 34⁰/ₒₒ salinity, the eggs in the endogenous vitellogenic oocytes and exogenous vitellogenic oocyte stages. The other impact of salinity is the reduction of some of the cells’ organelle among other egg cells, fibrous connective tissue, and follicle cells

Ratih Purnama Sari — 2024-06-01

Most Sardinella fimbriata in Muara Angke are caught using mini purse seine. Sardinella fimbriata is not a seasonal catch because it’s often caught by mini purse seines in all seasons. The sustainability of the use of Sardinella fimbriata needs to be guaranteed by studying its biological aspects. Therefore, research was carried out related to biological aspects based on the long-weight relationship of Sardinella fimbriata and reproductive aspects, namely based on the size of first maturity. Field data collection was carried out for 21 days with a total of 14 fishing trips. During these 14 trips, settings were carried out 21 times. The fishing ground of KM. Sukma Wijaya is in the Java Sea Waters area (WPP NRI) 712, which is around Bidadari Island, Lancang Island, and Fort Martelo. Data analysis that used in this study is the long-weight relationship of sardinella fimbriata). Sardinella fimbriata that caught at Muara Angke has the range of total length about 120-160 mm and a weight range of 20-45 grams. This indicates that Sardinella fimbriata has undergone a gonad maturation process. Based on the length-weight relationship, it is said that the Sardinella fimbriata in Muara Angke Jakarta has a negative allometric growth pattern with b value is about 3.26. This can be caused that these are in coastal waters with high fishing pressure so their movement activity is also high.

Improvement of Water Quality Parameters Using Moringa Seeds and Activated Zeolite in a Simple Brackish Water Filter Prototype

Yono — 2024-06-01

Providing a cheap and drinkable water is a major problem for people living in brackish water coastal areas. Residents usually buy water from refill water depots or are forced to use slightly brackish well water for cooking and drinking purposes. Consuming water that contains high levels of salt and other contaminants can be harmful to health in the long run. This study aims to produce a simple brackish water filter that is cheap and can be operated on a household scale to meet the cooking and drinking needs of people in coastal areas. The filter tool is made using filter materials in the form of NaOH activated zeolite, Malang blacksand, greensand, activated charcoal and sponges. Deposition of dissolved particles using moringa seed powder is done before the water is put into the filtering process. Filtration was carried out with a duration of 4, 8, 16 and 32 hours. Salinity, pH and DO of water before and after filtration were measured for each filtering duration, while other parameters were only measured for filtered water with the period of 32 hours. The filter successfully improved the parameters of salinity, pH, turbidity, iron content, hardness, chloride content and organic matter content and can be used as drinking water by cooking it first to remove the chloride content which is still above the maximum specified standard.
