Abstract
The massive plastic production in Indonesia is an effort to meet the demand for the food packaging sector, which is nearly 40% of the total plastic demand. Plastics are not environmentally friendly because they are not degradable. Carrageenan-based biodegradable packaging in the form of bioplastic is an alternative, but it has disadvantages such as low resistance to water. Modified starch can be used to improve bioplastic characteristics. This research aimed to determine the application of modified starch in biodegradable packaging to its biodegradability and mechanical properties. This research is experimental which consists of primary parameters and supporting parameters. The independent variables used were modified starch (0, 1, 1.5, and 2 g). The experimental design used a completely randomized design (CRD) and data analysis using the Analysis of Variance (ANOVA) and the DMRT follow-up test. The results showed that the application of modified starch in biodegradable packaging based on carrageenan had a significant effect (p <0.05) on water resistance and the best test results were 2 g of modified starch (P3) with a water resistance value of 50.96% ± 4.86. Meanwhile, the results of biodegradability, tensile strength, and elongation were not significantly different.

Abstract
Snakehead fish (Channa striata) is a carnivorous freshwater fish commodity that has high economic value. However, this cultivation takes a long period due to its poor growth rate. Maggot has been proposed as a possible alternative to fish feed because it is less expensive and has nutritional value. This study aimed to determine the effect of the dietary combination of maggot and pellets on the growth rate and feed conversion ratio of snakehead fish. This study used a completely randomized design (CRD) with five treatments and four replications. The treatments were P0: 100% pellet, P1: 100% maggot, P2: 75% pellets and 25% maggot, P3: 50% pellets and 50% maggot, P4: 25% pellets and 75% maggot. The result showed a combination of pellet feed and maggot feed had a significant improvement (p<0.05) on the growth rate of snakehead fish. However, there were no significant differences in the feed conversion ratio (p>0.05). The treatment of 75% pellet feed and 25% maggot feed (P2) generated the highest growth rate of 0.154 g/day and the lowest feed conversion ratio of 3.121. It can be concluded that the combination of maggot and pellet experienced better growth performance and feed conversion ratio of snakehead fish.

However, microbial infection become restricting component that can cause economic loss in carp production and the use of commercial antibiotics for therapy produces adverse side effects. This study was conducted to evaluate the potential of Ocimum sanctum L. crude extract on haematology of Cyprinus carpio against A. hydrophila infection. For this purpose, fish that have been infected were immersed in different doses of Ocimum sanctum L. crude extract (50, 150, 250, 350 ppm) and compared with the control group. After 1 week of immersion, total erythrocytes, total leukocytes, and deferential leukocytes (neutrophils, monocytes and lymphocytes) were recorded. The result showed that significant increase of total erythrocytes was obtained at the concentration of 350 ppm Ocimum sanctum L. crude extract. Furthermore, decreasing of the total leukocytes about 55.06×103 to 25.77×103, also decreasing deferential leukocytes (monocytes 40%, neutrophils 31% and lymphocytes 49% from the positive control). These results suggested that 350 ppm of Ocimum sanctum L. crude extract is beneficial to enhance the haematological status of common carp against A. hydrophila.
