Abstract

Bawean Island is one of the islands in Gresik Regency, East Java, where almost all its territory is a coastal environment. This region's tidal oceanographic condition is critical because this area has a lot of potential for marine tourism and relatively shallow waters. This study aims to determine the tidal characteristics in the waters of Bawean Island, East Java, using the Admiralty method. This method was chosen because it can calculate the tidal component with only 15 days of data and can be used in various water conditions. The data used is tidal data from the Geospatial Information Agency (BIG) on November 1-15, 2020. From this research, it can be concluded that tidal analysis using the Admiralty method produces nine components, including M2, S2, N2, K1, O1, P1, M4, MS4, and K2. The four components determine the type of tide, namely O1, K1, M2, and S2, with amplitude values of 11.79347, 30.14857, 55.72241, and 63.69851. The calculation with the Formzahl number equation yields a value of 0.3512 (0.25 <F <1.5), which means that the tidal type in Bawean Island, East Java, has a mixed type with a semidiurnal tendency (double daily).

Abstract

Tilapia (Oreochromis niloticus) strain of Sultana (superior selection of salabintana) is a new variety developed by the Center for Freshwater Resources Development (BBPABT) Sukabumi, West Java. Sultana tilapia is the result of crossing 10 superior varieties such as gift tilapia, jica, white, and other superior tilapia. Many factors cause the high price of feed, one of which is dependent on imported raw materials for feed manufacture. This study aims to assess the effectiveness of the use of local raw materials with different protein content in feed for the growth of tilapia and reduce production costs by using local raw materials as feed ingredients. This research was conducted from March 21 to June 19, 2020 at the Integrated Field Laboratory of the Faculty of Agriculture, University of Lampung. The design used in this study was a completely randomized design (CRD) consisting of four treatments with three replications. The treatments given included 30% protein treatment (A), 33% protein treatment (B), 36% treatment (C), and commercial feed control (D) for 60 days of maintenance. The data obtained were analyzed by using the ANOVA test and followed by the Duncan test. The results obtained in this study are that treatment B has the best FCR value and is significantly different compared to other treatments so as to produce the best growth. Besides that, treatment A and C also had a significantly different FCR value compared to the control.

Abstract

Sangkuriang catfish (Clarias gariepinus) is a cultivated species favored by Indonesian and has great potential for development. However, the obstacle to the success of catfish cultivation is a disease. One alternative to overcome this problem is by giving immunostimulants from natural ingredients. The purpose of this study was to test the effectiveness of feeding with moringa leaf powder on non-specific immunity and growth performance of sangkuriang catfish. The study used a completely randomized design (CRD) with 4 treatments (100% commercial feed, commercial feed with 1.5% Moringa leaf supplementation, commercial feed with 3% Moringa leaf supplementation, and commercial feed with Moringa leaf supplementation 4.5%, and 3 replications. The results showed that the commercial feed with 4.5% moringa leaf supplementation gave the best results for total erythrocytes of 5.97x104 cells/mm3 and MCV of 92.10 fl, and increased the absolute weight growth of 46.42 g. However, it did not show a significant effect on total erythrocytes, hemoglobin, hematocrit, MCHC, MCH, MCV, total leukocytes, leukocyte differentials, phagocytic activity, phagocytosis index, absolute weight growth survival rate, and the value of the feed convention ratio (FCR)

Abstract

The success of a culture depends on the quantity and quality of water used in fish culture without water exchange, the concentration of aquaculture waste such as ammonia (NH3) will increase very rapidly and is toxic to the cultivated organism. One of the innovations applied in fish farming is integrating plants through an aquaponics system. This study aims to determine the effect of using a settling tub in reducing ammonia waste (NH3) and growth in tilapia aquaculture using an aquaponic tidal system. The size of the initial tilapia seeds used is 3-4 cm. There are two treatments used, without settling tub (A) and addition of settling tub (B) with three replications. However, the results showed no significant differences (P>0.05) between treatments for all parameters observed. It is necessary to carry out further research on different fish and plants to see the optimization in reducing ammonia waste (NH3).
