Abstract

This study was carried out in the present farming sites of Kappaphycus alvarezii in Minahasa penninsula, Jayakarsa village of North Minahasa, Sondaken of South Minahasa, Buku Tengah of  Southeast Minahasa, and Tumpaan of Minahasa Regencies. It was aimed to know the farming system and financially analyze whether the farming business is feasible or not.  Data were collected through observations, questioneers and interviews.  Literature reviews and financial analyses were also done to know the revenue, the feasibility of  seaweed, K. alvarezii, farming business and its development. The farming system in Minahasa penninsula generally used longline method.  It is used because of being resilient to strong wind, cheap, and easily implemented and long lived so that the line could be repeatedly used up to  4-5 years.  Financial analyses found that among 4 study sites, the highest B/C ratio was recorded in North Minahasa, 6.06, followed by South Minahasa, 2.75, then Southeast Minahasa and Minahasa, 1.67, and BEP values were also different among regencies.  Furthermore, NPV, IRR, ROI and PP of all study sites belonged to feasible criteria for development.  Different conditions among regencies resulted from different geographic conditions affected the planting system.

Abstract

The purpose of this study was to determine the concentration of the use of the best fermented coconut pulp in feed on the growth of tilapia.  The research  used 12  nets  measuring 1x1 m placed in a concrete pond measuring 3.5 x 5 cm. The treatments were A (without fermented coconut pulp), B (10% fermented coconut pulp), C (20% fermented coconut pulp), and D (30% fermented coconut pulp). The experimental method used was a completely randomized design with 4 treatments and 3 repetitions. Data collected were absolute growth, daily growth, relative growth, and feed efficiency. The results of the variance analysis showed an influence in the growth of tilapia size 5-8 cm. The best growth and feed efficiency value occurred in treatment D Thus  the use of  30% fermented coconut pulp in fish food could improve the growth of tilapia.Key words : fermented coconut pulp, tilapia, growth feed efficiency

Abstract

The purpose of this study was to determine the best culture medium for producing maggot (Hermetia illucens) and to determine the production quantity in each different medium.  This research was controlled two times a day at 09:00 a.m. and 16:00 p.m. Cultivation media were prepared from coconut pulp, tofu pulp, rice bran and restaurant wastes. Each medium was weighed as much as one kg and then placed into a culture container. The research used Completely Randomized Design consisting of 4 treatments, each with three replications. The parameters observed consisted of temperature and pH of the media  measured at 07.00 am and 17.00 pm, and maggot production measured on the last day. During the ten days of experiment, the production of maggot in the treatment using restaurant waste media was significantly different as compared to other treatments. This study found that a good medium for the production of maggot was prepared using restaurant waste. Keywords: Hermetia illucens, coconut pulp, restaurant waste

Abstract

The purpose of this study was to identify chydoridae using conservative way, while the observations of the life cycle was done through a microscope to determine the egg production per parent and length of life. Individual chydoridae acclimatized to reach 10 generations (1 month), and 10 females were isolated for the production of seedlings. Based on literatures review, chydoridae used was derived from subfamily Aloninae (Alona spp.); while studies on the life cycle found: the egg size of chydoridae 150.2 ± 22.4 μm, and neonates have an average size of 291.82 ± 3.06 μm, and reached adult size after 2.3 ± 0.5 days, with an average size of 441.22 ± 10.2 μm. Time of embryonic development occured for 1-2 days. On the entire life cycle, only 2 eggs could be produced per individual. Based on this study, the number of eggs produced by the female during its lifetime ranges between 30-60 eggs. Similarly, the length of life of this organism on average 47.2 ± 11.7 days, with the longest lifespan was achieved 60 days. It was found also the maximum size was 1,037 ± 8.5 mm; while the average size of an organism's body was 800.42 ± 56.3 μm.Keywords: chydoridae, identification, life cycle, Alona spp

Abstract

In increasing fish farming production, it is very dependent on the availability of fish feed which has recently been expensive. To overcome this, was necessary to find alternative feeds that have nutritional value according to the needs of cultivated organisms. Maggot (Hermetia illucens Linn.) is a black soldier fly larvae that has a chewy texture, high protein and has the ability to secrete natural enzymes that help improve the digestive system of fish. . The aimed of this research was to find out the amount of maggot (H. illucens Linn.) production in several cultivation media with different treatments. The  results of the study found that it took up to 2 weeks to produce maggot that had ready to be used as feed. Maggot had the potential to be cultivated as an alternative to fish feed.

Abstract

This study aimed to analisys the physical-chemical parameters of Bahoi waters. A total of 3 Stations water samples were carried out in 2018 and analyzed for physical- chemical parameters such as turbidity, water temperature, total suspended (TSS), salinity, pH, dissolved oxygen using an Horiba instrument and laboratory analysis for NH3, and P at the Agency for Industrial and Development Research Institute of Standardization and Industrial Manado. The obtained values of each parameter were compared with the standard values set by the KEPMEN-LH No. 51/2004 for marine biotas. The values of each parameter were found to be within the safe limits set by the WHO and NDWQS. Overall, the waters from all the stations were found to be safe as aquaculture area. However, it was also important to investigate other potential water contaminations such as chemicals and microbial and radiological materials for a longer period of time in order to assess the overall water quality of Bahoi waters.
