Abstract

Papua island has the largest mangrove forest area in Indonesia, reaching 1,350,600.00 Ha which accounts for half of the entire area of mangrove forests in Indonesia. One of the locations with a fairly extensive mangrove forest in the Jayapura area is in Youtefa Bay. Although mangroves have large environmental potential, local people use the forest as building materials, food, fishing tools, and medicines. Mangrove forests have an active role in maintaining global climate stability in the world, forest vegetation will fix CO2 through the process of photosynthesis. Mangrove forests per hectare can store up to four times more carbon than other tropical forests worldwide. This research aims to estimate the amount of carbon stock Rhizophora mucronata can store in mangrove forests in Youtefa Bay, particulary in Tobati, Enggros and Entrop Villages, Jayapura, Papua. The method used in this study was using Allometric Equations to estimate the biomass carbon from Rhizophora mucronata and compared to three different satellite imagery algorithms. The research results showed that the biomass of Rhizophora mucronata stands in Entrop Village was the highest and the lowest in Enggros Village. In addition, the results of measurements of carbon stocks in Tobati and Enggros Villages showed that the values were similar, only 0.23 kgC/m2 with carbon stocks in Entrop Village reaching 19.46 kgC/m2. Based on the results of measuring satellite imagery with three different algorithms, it was found that using the EVI algorithm produced the smallest Standard Error of Estimate, which was 1.63 kg C/m2. The estimated total carbon in Youtefa Bay is 213,424.69 kg C/m2.Keywords:AllometricCarbon StockRhizophora mucronataYoutefa Bay

Abstract

The purpose of this study was to assess the microbiological quality of smoked fish at the processing center in Jayapura City, Papua. 100 kilograms of smoked fish were tested, samples were taken from producers, distributors, and retailers at three distribution levels. Microbiological tests included identification of Salmonella sp. bacteria and Total Plate Count (TPS) tests. The results of the study were conducted using ANOVA and DMRT further tests at a significance level of 95%. The average TPS value at all distribution levels ranged between 3.379 and 3.509 log cfu/g, which is still within the safe limit for consumption (p>0.05). Each sample tested did not show any Salmonella sp. contamination. This study shows that smoked fish products in Jayapura City are microbiologically safe, but care during distribution needs to be improved, especially in terms of packaging and cleanliness, so that the product continues to satisfy consumers. Consumers can be more satisfied and shelf life can be extended with better hygiene, packaging, and better distribution chain management. The results of this study provide important insights for producers, consumers, and related parties about the quality of Jayapura smoked fish. This information can be used as a basis for fisheries policy and product quality improvement.

Abstract

This research is based on the critical role of social marketing in raising awareness and promoting healthy behaviors during the COVID-19 pandemic, particularly in Jayapura City, where challenges persist in disseminating effective information and influencing public behavior regarding health protocol adherence. The study aims to analyze the implementation of social marketing through promotional media, such as posters and health protocols displayed in public areas, in enhancing knowledge and influencing behavioral changes among the residents of Jayapura City in COVID-19 prevention. A qualitative case study method was used to evaluate the implementation of social marketing in COVID-19 promotional media and its impact on public knowledge in Jayapura City. Data collection was conducted through semi-structured interviews with respondents from diverse social backgrounds, as well as direct observation of promotional media distributed throughout the city. The findings reveal that while promotional media, such as COVID-19 posters and health protocols displayed in public areas, succeeded in improving the public's basic understanding of the importance of health protocols, there were significant barriers to the consistent application of such behaviors. Factors such as limited access to information, a lack of in-depth understanding, and social resistance to behavioral changes posed considerable challenges to enhancing the effectiveness of the campaign. The research also found that while the campaign positively impacted awareness levels, a more integrated and contextual approach is needed to achieve comprehensive behavioral change among the community.
