Abstract

The very low survival rate of larvae is a limiting factor in seed production for yellow fin tuna. Larvae die mass on day ten to juveniles, with a survival value of less than 0.05%. The main factor causing the death of tuna larvae is the circle of water currents in the rearing tank which results in surfacing death and sinking death. This study aims to determine whether yellowfin tuna (YFT) larvae reared at different aeration designs in rearing tanks have an impact on larvae survival. The studi was designed using a Completely Randomized Design (CRD) with three treatments and three replications: four aeration points in the middle as A, four aeration points at the bottom of B and a combination of two middle aeration points and two aeration points at the bottom C. One day old larvae were stocked in round tanks with a volume of 700 L at a density of 10.0000 individuals per tanks. Observations survival, daily growth rate, diversity coefficient and water quality were carried out for 13 days of rearing. Research result show Rearing larvae with aeration design at the bottom and a combination has a significant effect on the survival of yellow fin tuna with survival 0,31±0,04% and 0,30±0,06%. Daily length growth rate, coefficient of variation and water quality parameters in the three treatment had no significant effect. Treatments A, B and C extended value of growth rate of length 6%, 5,69% and 5,62%. Value of coefficient of diversity 4,66%, 5,69% and 4,79%.

Abstract: Sargassum sp. seaweed is included in the category of brown macro algae that has not been cultivated and has not been optimally utilized. Sargassum sp. has economic value because it contains alginate and iodine which are utilized in the food, pharmaceutical, cosmetic, and textile industries. Sargassum sp. has a high carbohydrate content that can be converted into bioethanol and bioenergy. So that this potential can be developed to improve the community's economy and increase efforts to protect the environment from pollution from the use of fossil fuels. Sargassum sp. seaweed can be found in the waters of Gerupuk, Sengkol Village, Pujut District. Gerupuk is a hamlet that is included in the Mandalika Creative Economic Zone, among the community's livelihood activities is seaweed cultivation. Seaweed farmers in Gerupuk only cultivate K. alvarezii seaweed. They only know Sargassum sp. as a seaweed that grows wild and has no economic value. Sargassum sp. in Gerupuk is not utilized, so it needs to be educated on its benefits and utilization. This community service activity will be carried out in Gerupuk Hamlet, Sengkol Village, Pujut District, Central Lombok Regency. The output targets of this community service activity are appropriate technology for the cultivation of Sargassum sp. for bioethanol production, publications at national community service seminars and articles published in national community service journals indexed by sinta. The stages of implementing this activity are coordination of activities, counseling, demonstration of Sargassum sp. seaweed cultivation, mentoring, evaluation of activities, and collaboration with the Lombok Marine Aquaculture Center (BPBL). The expected results of this activity are that seaweed farmers in Gerupuk can cultivate Sargassum sp. to improve the household economy and the community economy. Keywords: Seaweed, Sargassum sp., cultivation, bioenergy, bioethanol.

Abstract

Penelitian ini bertujuan untuk mengetahui metode aklimatisasi salinitas yang terbaik terhadap kelangsungan hidup benih ikan nila (Oreochromis sp.). Metode aklimatisasi salinitas yang digunakan yaitu metode interval dan metode kontinyu. Aklimatisasi dilakukan selama enam hari dengan peningkatan salinitas 5 ppt/hari hingga mencapai salinitas 30 ppt dan dipelihara selama tujuh hari. Hasil penelitian menunjukkan, pada masing-masing metode interval atau metode kontinyu tidak memberikan pengaruh nyata terhadap tingkat kelangsungan hidup benih ikan nila (Oreochromis sp.). Hasil uji t rerata antara metode kontinyu dan metode interval menunjukkan bahwa, metode kontinyu memberikan nilai kelangsungan hidup yang lebih tinggi bagi benih ikan nila (Oreochromis sp.).

Abstract

Community service is an activity with the aim of providing skills-based literacy to community groups, in this case the lobster cultivating community in Ujung Betok Village, Pemongkong Jerowaru, East Lombok. The methods used during training are interactive discussions and work practices. This training activity was attended by lecturers from the Aquaculture Study Program as training resource persons, students and groups of lobster farmers. The activity took place at the residence of the group leader as a gathering and discussion forum for lobster cultivators in Ujung Betok Village. This activity was carried out as an effort to reduce dependence on trash fish feed, the availability of which fluctuates greatly according to the fishing season. Apart from that, this training is expected to be able to increase the efficiency of lobster cultivation. This training includes material on proper nutritional composition, ingredient mixing techniques, processing processes, and good feeding methods. The results of this training show an increase in the participants' ability to produce quality feed which is expected to have a positive impact on the growth and health of the lobsters being farmed. Apart from that, this initiative is also expected to contribute to improving the welfare of local communities through the development of more sustainable and efficient lobster cultivation.

Abstract

Fish diseases are one of the primary challenges faced by fish farmers, including tilapia fish farmers using tarpaulin ponds in the village of Kramajaya, West Lombok. Fish diseases can lead to significant losses in the fish farming business. Therefore, education on the management of fish diseases is essential to assist farmers in safeguarding their fish stocks and ensuring the success of their aquaculture endeavors. This endeavor aims to provide education to tilapia fish farmers using tarpaulin ponds in Kramajaya village, West Lombok, regarding the management of fish diseases. The education methods employed encompass the dissemination of information about the causes, symptoms, prevention, and treatment of fish diseases, along with aquaculture practices that can help mitigate the risk of diseases. The results of this education show an improvement in the knowledge of fish farmers regarding the management of fish diseases. They become more aware of the signs of fish diseases and are capable of taking appropriate preventive measures. Furthermore, they also understand the importance of maintaining water quality and the cleanliness of tarpaulin ponds as disease prevention measures. This education also provides a better understanding of the use of medications and proper medical actions in case fish diseases occur. Consequently, fish farmers can respond more promptly and effectively to fish diseases, which, in turn, can enhance the production of tilapia fish and the overall success of their aquaculture businesses.
