Abstract

Yubiah Village is a village located in North Ayamaru District, Maybrat Regency, West Papua Province. The community of Yubiah Village is largely engaged in freshwater fish farming, and one of the main cultured species is Nile tilapia. This fish is chosen not only because it is easy to cultivate but also because it has good marketability. Freshwater sources in Yubiah Village are abundant, making freshwater aquaculture easy to carry out. The purpose of this study was to determine the effect of silk algae (Chaetomorpha sp.) as an alternative feed on the growth and survival of Nile tilapia. The research was conducted from October to November 2022 in Yubiah Village, North Ayamaru District, Maybrat Regency, West Papua Province. This study used a Completely Randomized Design (CRD) consisting of three treatments and one control. The results of the study led to the following conclusions: The measurement of absolute weight gain of Nile tilapia showed that the best growth occurred in Treatment C with 80 grams of silk algae as an alternative feed, followed by Treatment B with 60 grams, and Treatment A with 75 grams, while the lowest growth was obtained in Treatment D (without silk algae). The highest survival rate of Nile tilapia was found in Treatment C (28 grams), where fish were given a higher amount of silk algae three times a week. This was followed by the other treatments.

Abstract

Indonesia is said to be one of the countries contributing to plastic waste in the world. Therefore, the Government through the Ministry of Maritime Affairs and Fisheries has launched a priority program for handling plastic waste in the sea as an effort to reduce plastic waste. One form of support in handling plastic waste is to identify the potential for research-based waste generation in coastal areas and small islands. This research was conducted on Soop Island, Sorong Islands District, Sorong City, Southwest Papua from October to November 2024 with the aim of analyzing and identifying non-organic waste by knowing the amount, weight, and density of waste. This research method uses qualitative and quantitative. Qualitative research methods include observation, visual analysis, literature studies, and interviews. For quantitative methods calculating the amount of waste based on type per unit area. From the results of the study, it is known that the non-organic waste identified on Soop Island consists of plastic, plastic foam/styrofoam, glass and ceramics, metal, paper and cardboard, rubber, and other materials. The type of plastic waste dominates the most with a density of 8.33 pcs/m2 with a waste weight reaching 238.75 gr/m2. Meanwhile, the lowest waste density is in the paper and cardboard waste type with a density of 0.03 pcs/m2 with a weight of 2.38 gr/m2.

Abstract

Coral reefs are tropical marine ecosystems that are very important for the sustainability of fishery resources and coastal protection. This study aims to evaluate the condition of live stony coral cover at Suprau Beach, Maladoom Mes District, Sorong City using the Point Intercept Transect (PIT) method. Observations were conducted at three stations at a depth of 3-5 meters. The results showed that the average live coral cover was 45.33%, which is classified as moderate. Specifically, Station I had excellent coral cover (80%) dominated by Non-Acropora corals of the Coral Branching type from the Porites family; Station II showed moderate conditions (34%) with a dominance of Non-Acropora corals of various life forms; and Station III was in a damaged condition (20%) with high coverage of dead corals covered with algae (52%) and sand (24%). Water quality conditions at all three stations still support coral growth, with parameters such as temperature (29-32°C), salinity (31-35 ppt), pH (7.5 ppt), and water clarity (4-8.5 m) within the optimal range. High sedimentation at Stations II and III is the main factor limiting coral growth, caused by community activities such as beach reclamation, pier construction, and hill excavation around the waters. This study provides basic information for the development of strategies for the rehabilitation and management of coral reef ecosystems in Sorong City.

Abstract

Seagrass beds are one of the ecosystems located in coastal areas or shallow marine waters. The uniqueness of seagrasses compared to other marine plants lies in their extensive root system and rhizome network. This type of rooting system causes seagrass leaves to become dense, which greatly benefits the productivity of the seagrass bed ecosystem. This study aimed to determine the species diversity and condition of seagrass beds on Suprau Beach, Maladum Mes District. Three seagrass species were found on Suprau Beach: Halodule pinifolia, Halodule uninervis, and Cymodocea serrulata, with relative cover percentages of 50%, 33.3%, and 16.7%, respectively. Based on the analysis of seagrass bed conditions in Suprau Waters, the ecosystem was classified as damaged or poor/unhealthy and impoverished according to the Indonesian Minister of Environment Decree No. 51 of 2004.

Abstract

Mangrove forests on the coast of West Papua hold high ecological and economic values, yet utilization pressure continues to increase. This study aimed to analyze the impacts of mangrove utilization activities on ecosystem conditions and on the socio-economy of the community in Kladufu Village Km 10, East Sorong District, Sorong City. The research was conducted with using a descriptive survey method with semi-structured interviews of 31 purposively selected respondents. Data were analyzed descriptively (quantitative and qualitative). Results showed that most respondents were male (58.1%); of productive age, with low education levels (elementary school 38.7%, junior high school 35.5%); and worked as housewives, stone collectors, mangrove loggers, or fishermen. As many as 67.7% of respondents very frequently utilized mangroves, mainly for firewood and construction materials. Logging frequency was very high (61.3%). Nevertheless, 41.9% of respondents perceived mangrove conditions as better than three years earlier due to replanting activities. Community participation in management was mostly voluntary (71.0%) and motivated by confidence in local knowledge (80.6%). A total of 83.9% desired involvement from the planning stage through to benefit sharing. The utilization impacts on the ecosystem were twofold: improvement in rehabilitated areas versus degradation elsewhere. Impacts on the community were reflected in high economic dependence, alongside strong ecological awareness and social capital. Capacity building and livelihood diversification are needed to achieve mangrove sustainability.

Abstract

Large pelagic tuna (Thunnus sp.) is a high-value fishery resource that significantly contributes to Indonesia’s fishing industry. This study evaluates the effectiveness of two primary fishing gear types—hand line and kite line—in tuna fisheries in Makbon waters, Sorong Regency, West Papua. Field research was conducted using a survey approach with direct observations on 14 fishing trips. Results demonstrated that hand line yielded 52 tuna individuals (65.8% effectiveness), while kite line yielded 27 individuals (34.2% effectiveness). This difference is significant and influenced by technical factors including operational depth, gear selectivity, and target fish behavior. Hand line effectively reaches optimal tuna depths and exhibits higher selectivity for catching marketable-sized individuals. This research emphasizes the importance of appropriate gear selection in enhancing catch productivity while maintaining tuna resource sustainability. Policy recommendations include regulating hand line use as the primary fishing gear and implementing monitoring systems to ensure the capture of adult fish
