Abstract

The purpose of this study was to determine fishermen's income using hand line fishing gear in Banawa Village using primary data for 50 respondents representing the entire population of the Fisherman Community in Banawa Village. Data collection was carried out using interviews and documentation methods. The analytical method used is descriptive quantitative. The collected data is processed and presented in tabular form. The study results show that the fishing community in Kampung Banawa still needs a higher understanding of knowledge and technology. This has not reduced the enthusiasm of fishermen in Kampung Banawa to go to sea actively, even though the price of fish in the market could be better. There are differences between hand-line fishermen based on the boat used. Hand line fishermen with rowing boats earn Rp.70,000/week, hand line fishermen using ketinting engine boats Rp.120,000/week, and hand line fishermen using 15PK outboard motors make Rp.200,000/week. Institutions supporting fishermen's income include Fishery Cooperatives, Banking (BNI), and fish markets.

Abstract

Delays in hatching of fish eggs are influenced by several factors such as water quality instability during rearing, including; temperature, DO, pH. Papaya leaf is one of the plants that can be used to accelerate the hatchability of fish eggs. Papaya itself can be used as a component to boost the immune system because it contains the enzyme papain. The purpose of this study was to compare the hatchability of nile tilapia (Oreochromis niloticus) eggs in the treatment of papaya leaf extract (Carica papaya) with different doses. This research was conducted at the Punten Cultivation Fisheries Installation, Batu City in December 2022. Using a Completely Randomized Design (CRD) where there were 4 treatments, namely: A) papaya leaf extract 4 mL/L, B) papaya leaf extract 6 mL/L, C ) papaya leaf extract 10 mL/L, and D) control without treatment. In each treatment there were 3 repetitions. The ANOVA test was used to compare the effect of papaya leaf extract on hatchability of tilapia eggs, and was followed up with the BNT test if there were significant differences in the treatments. The results showed that there were significant differences in the treatment with the addition of papaya leaf extract on the hatchability of tilapia eggs, with 4 mL/L treatment) being the best treatment in increasing the hatchability percentage of tilapia eggs by 88.33%. There is a tendency that the higher the papaya leaf extract, the egg hatchability decreases.

Abstract

This study aims to investigate the impact of varying the depth of water on the growth and productivity of seaweed Kappaphycus alvarezii. The study was carried out in the seas of Pallette. The research methodology used in this study incorporates three different planting depth treatments, specifically 1.5 meters, 3 meters, and 4 meters. In each treatment, 50 grams of Kappaphycus alvarezii seeds per bunch were used. The findings of this study indicate that seaweed cultivation at a depth of 1.5 m yields significantly favourable outcomes compared to the treatments conducted at depths of 3 m and 4 m, where growth is comparatively less optimal. This occurrence can be attributed to the diminished level of light penetration at such a depth. There is an inverse relationship between the depth of seaweed planting and the rate of weight gain. The optimal depth for seaweed cultivation for 42 days is 1.5 meters, with an average specific growth rate of 3% daily. On the contrary, the treatment carried out at a depth of 1.5 m showed the most substantial increase in biomass, averaging 122 g. Additionally, the maximum yield of seaweed was observed in the same treatment, precisely measuring 1,208 g/m2.

Abstract

Global warming is becoming increasingly apprehensive day by day, marked by the continued increase in levels of carbon dioxide (CO2) in nature. One of the efforts made to reduce the effects of global warming is biosequestration by empowering photosynthetic organisms, one of which is seagrass beds. This study aims to measure the density and percentage of seagrass cover, biomass value, and estimate carbon storage in seagrass biomass in the form of tissue at the top (leaves and upright stems) and tissue at the bottom (roots and rhizomes), as well as estimate carbon storage in sediments. Sampling was carried out using line transect and quadrant plot methods at each station. Calculation seagrass carbon storage using the Loss of Ignition (LOI) method at the Soil Chemistry Laboratory of the Pangkep State Agricultural Polytechnic, a total of 5 species of seagrass were found, namely Enhalus accoroides, Thalassia hemprichii, Halodule uninervis, Halopila ovalis, and Cymodocea rotundata. The average seagrass carbon storage on Badi Island is 18.92 gC/m2, or 0.189 MgC/ha. The species that act as the largest contributor to carbon storage are Cymodocea rotundata, namely 35.44 gC/m2, and Halopila ovalis, which acts as the lowest contributor to carbon storage, namely 1.92 gC/m2. The average seagrass carbon storage at the bottom of the substrate was three times greater than that at the top of the substrate, namely 14.10 gC/m2 at the bottom and 4.82 gC/m2 at the top. The average carbon storage in sediments is 10.98 gC/m2, or 0.109 MgC/ha.

Abstract

Gastropods are marine biota found in the waters of Pulau Terkulai, Tanjungpinang City and are one of the catch of fishermen. However, information on the structure of the gastropod community in these waters is not widely known. The purpose of this study was to determine the types of gastropods, gastropod community structure, and the relationship between gastropod community structure and environmental parameters in the waters of Terkulai Island. This research was conducted in April-August 2023. Determination of sampling points using random sampling method as many as 30 points with sampling plots measuring 1x1m2. The results of this study obtained 650 individuals with 15 species of gastropods. The highest density was found in Batillaria attramentaria species with a total of 12.20 ind/m2. Gastropod community structure diversity value (H') ranged from 1.512 which is classified as moderate. The uniformity value (E) ranges from 0.558 which is classified as moderate and the dominance value (D) ranges from 0.353 which is classified as moderate. The results of the measurement of the physicochemical parameters of the waters are still at a feasible threshold for gastropod life. The principal component analysis (PCA) shows that the density with water parameters has a positive correlation with temperature and organic matter.

Abstract

As part of the life support system, the mangrove ecosystem in the Rawa Aopa Watumohai National Park (TNRAW) has an ecological function as a spawning ground for fish in the waters, a filter for sea water intrusion into the mainland, and an absorber of heavy metals that are harmful to life, habitat for wildlife. migratory bird shelters; as well as barrier to coastal abrasion, hurricane winds and tsunamis. Aim of this study were to determine the critical level of mangroves using the terrestrial method (field survey) and to formulate the factors causing the criticality of mangroves in TNRAW. This research uses  vegetation and descriptive analysis. The results of this study indicate that there are four families and eight species of mangroves in the research location. The four families are Meliaceae, Rhizophoraceae, Avicenniaceae and Combretacea with the dominating family was Rhizophoracea. Mangroves species found were Xylocarpus granatum K., Bruguiera gymnorrhiza L., Rhizophora mucronata Bl., Rhizophora apiculata L., Ceriops decandra, Ceriops tagal, Avicennia alba and Lumnitzera racemosa.  The highest and lowest mangrove species diversity indexes in TNRAW were the seedling and tree strata, respectively with values 1,733 and 1,570. For the critical level of mangrove land measured at the four research stations, it shows that the mangrove ecosystem at the four research station is in a damaged condition. Causal factors of mangrove land critical in TNRAW were economic factors, education and skills, and weak of supervision of the authorities.

Abstract

The plant species mangrove has been knowed to be effective for the bio-desalination process. However, there is currently no scientific evidence supporting the ability of mangrove bio-desalination when implemented through the floating method. This laboratory-scale study aimed to evaluate the bio-desalination of several mangrove species using the floating method. This study consisted of four treatments and three replicates. Treatments included a control group without mangroves (treatment A) and three treatments using mangroves (treatments B, C, and D), Bruguiera sp., Rhizophora sp., and Avicennia sp., which were positioned floating in a tank using a tray. During the eight weeks of rearing, nutrients were provided through 60 mL liquid NPK fertilization. The results showed that there was a decrease in salinity concentration in all mangrove treatments between 22.5-23.9 ppt from the initial salinity of 30 ppt. Different results were observed for the treatment without mangroves, and the salinity concentration tended to increase until the end of the research to 31.6 ppt. The highest Salinity Reduction Efficiency (SRE) was achieved by Avicennia sp.. (25.1%), followed by Rhizophora sp. (22.8%), and the lowest in Bruguiera sp. (20.3%). The results of this study showed that bio-desalination using mangroves had a significant effect on SRE, and each treatment indicated a significant difference (p<0.05). The results of this study provide initial evidence of the potential of the mangrove floating method for bio-desalination of seawater into brackish water.

Abstract

The plant species of miana (Coleus scutellariodes) has been historically recognised for its antiviral properties.  However, there is currently no scientific evidence supporting the efficacy of miana leaf extract in preventing White Spot Syndrome Virus (WSSV) in tiger prawns (Penaeus monodon) when administered via feed. This study aimed to determine the impact of including miana leaf extract in the diet on the  survival percentage of tiger prawns that have been infected with the WSSV. The study was carried out between June and August 2023 in the Laboratory of Parasite and Fish Disease and the Hatchery Laboratory of Hasanuddin University. This study employed a completely randomized experimental design consisting of five distinct treatments, each with three replicates. The experimental treatments included the control group (treatment A), where food was provided without the inclusion of miana leaf extract. Furthermore, there were four treatment groups (treatments B, C, D and E) where feed was supplemented with miana leaf extract at concentrations of 125, 250, 500, and 750 µg mg-1 feed, respectively. Rearing was performed in two phases: preinfection (25 days) and post- infection (7 days). The statistical results of the statistical on pre-WSSV infection indicated that the addition of miana leaf extract to the food resulted in survival that was not significantly different (p>0.05). The results were different post-infection, significantly (p<0.05) the shrimp fed with the addition of miana leaf extract were higher than those without the extract. Furthermore, there was a significant difference in shrimp survival between pre- and post-WSSV infection. WSSV mitigation through immunostimulants using miana leaf extract, which is inexpensive and environmentally friendly, has the potential to minimize the impact of WSSV infection.
