Abstract

Chlorella sp is a kind of phytoplankton used as a natural food source for zooplankton, such as fish larvae and shrimp. Chlorella sp contains various nutrients that are good for the growth of fish larvae and shrimp. The success in cultivating Chlorella sp is closely related to the nutrient content at the time of cultivation. One alternative cultivation of Chlorella sp is using bean sprout extract and coconut water as the medium. Bean sprouts and coconut water extract can be used as a substitute for inorganic fertilizers. This research aims to determine the effect of bean sprout extract and coconut water on the growth of the density of Chlorella sp, as well as grasping the best dose that can be used to cultivate Chlorella sp. This research was conducted in July 2022 at the Aquaculture Environmental Quality Laboratory, Faculty of Fisheries and Marine, Universitas Riau. This research used a one-factor, Completely Randomized Design (CRD) with four treatments and three replications. The treatments as defined in this research were P0 (Walne fertilizer 1 mL/L as control), P1 (8% bean sprout extract + 10% coconut water), P2 (10% bean sprout extract + 12.5% coconut water) and P3 (bean sprout extract 12% + coconut water 15%). These results indicate that P3 (12% bean sprout extract + 15% coconut water) is the best treatment for the growth of Chlorella sp with a density of 1091.00 x104 cells/mL and a specific growth rate of 0.9607 sel/mL, which occurred on the sixth day.

Abstract

This research was conducted in January-July 2021 at the Marine Science Technology Biology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau. The purpose of the study was to see the effect of a combination dose of vitamin C and thyroxine hormone (T4) on the growth rate and survival of bream reared in a recirculation system. The method used was an experimental method using a factorial complete randomized design (CRD) with 2 factors and 3 replicates. The first factor is vitamin C, while the second factor is the dose of tyrrhosine hormone (T4) given during maintenance. The doses of vitamin C used in this study were; 0 mg/kg (V0), 500 mg/kg (V1), 1000 mg/kg (V2). Doses of thyroxine hormone (T4) used were doses; 0 mg/kg (H0), 4 mg/kg (H1), 6 mg/kg (H2), 8 mg/kg (H3).  The Asian redtail catfish used were 8-10 cm in size and reared in a round container made of PE plastic with a diameter of 56 cm and a height of 48 cm, totaling 36 units. The pellets used were Hi-Provite 781-2 with 31% protein, with feeding done 3 times a day ad satation. The results showed that the addition of vitamin C and thyroxine hormone influenced the growth of Asian redtail catfish reared in the recirculation system. The combination of vitamin C 1000 mg/kg and thyroxine hormone 8 mg/kg feed gives the highest growth and survival, seen from the absolute weight growth rate of 12.97 g, specific growth rate of 1.93 g/day, and 95% survival. Water quality during rearing was favorable for the growth of Asian redtail catfish, with temperature ranging from 28-30oC, pH 6.5-7.0, and DO 4.2-5.95 ppm.

Abstract

This study aims to determine the effect of feeding containing fermented chicken feather flour on feed efficiency and growth of striped catfish fry. The test fish used weighted 2.85 ± 0.33 g. The containers used for observing fish growth were 15 units of floating net cages made of gauze measuring 1x1x1 m with a stocking density of 25 ind/m, 3 and 5 units of aquariums measuring 60x35x40 cm as containers for observing the digestibility of feed with a stocking density of 25 ind/m3. This research method used a one-factor Completely Randomized Design (CRD) with five treatment levels and three replications. The treatments in this study were P0 (feed without fermented feather meal), P1 (feed containing 7.5% fermented feather meal), P2 (feed containing 15% fermented feather meal), P3 (feed containing 22.5% flour fermented chicken feathers), and P4 (feed containing 30% fermented chicken feather flour). The test feed protein was about 40%. The amount of feed given is 5% of the body weight of the fish with a frequency of 3 times a day, namely morning, afternoon, and evening. Fish rearing was carried out for 56 days. Measure the digestibility of feed by giving feed containing an indicator of 0.5% chromium oxide (Cr2O3). Feed is offered three times a day, namely morning, afternoon, and evening, as much as 5% of the body weight of the fish. The feces excreted by the fish are then collected and dried. The collected feces were analyzed for protein content and Cr2O3 to obtain feed and protein digestibility data. The results of this study indicated that the best treatment was P3 (feed containing 22.5% fermented chicken feather meal), resulting in feed digestibility of 55.36%, protein digestibility of 85.39%, feed efficiency of 83.59%, protein retention of 36.33%, specific growth rate of 3.38%, and survival of 92.00%

Abstract

This research analyses the suitability of permits for using mangrove wood in Karimun Regency for charcoal making, which has been going on for a long time. This charcoal was traded for local and foreign needs even before Indonesian Independence. However, it was only in 2010 that the official IUPHHK-HTR permit was enacted to regulate this activity.This study aims to analyze the suitability of forest area functions in community plantation forest permit areas based on the provisions of forestry laws and regulations, calculate the area of degraded/deforested as well as reforested forest cover using satellite image interpretation results, and identify institutions involved in processing mangrove wood into charcoal. The results showed that 59.55% of the forest area followed the permit, but there was deforestation of 802.29 ha (27%) and degradation of 72.53 ha (32.44%). On the other hand, reforestation efforts of 1,446.32 hectares were also carried out.This research was conducted using normative or doctrinal legal and overlay methods. The methods used in this research consist of normative or doctrinal legal research methods and overlay methods. Normative legal research focuses on the scope of legal conceptions, legal principles, and legal rules governing the suitability of forest area functions and granting social forestry licenses for community plantation forests. At the same time, the overlay method combines information from various maps. Various parties are involved in mangrove charcoal management, ranging from the Ministry of Environment and Forestry, Kepulauan Riau Provincial Government, Karimun Regency Government, and Wana Jaya Karimun Cooperative to 30 business license holders and charcoal collectors.This research recommends evaluating mangrove IUPHHK-HTR policies to ensure forest sustainability and balance between utilization and sustainability
