Processing is the way to solve that problem. Nasu palekko is a signature dish from South Sulawesi which made from duck meat and full of local spices. Nasu palekko has potentially fat oxidation reactions that impacted on decreasing quality. The addition of natural antioxidant ingredients can inhibit the fat oxidation process. This study was aimed to analyze the physicochemical, microbiology characteristics, and fat oxidation intensity during storage at room temperature with different processing method and shelf life. This study was used a completely randomized design (CRD) factorial 2x3 with 3 replications, consisting of 2 processing method (dry processing, wet processing) and 3 storage time (0 days, 2 days, 4 days). The obtained data were analyzed using analysis of variance, and the significant result was further being tested by the Tukey test. The results showed that the treatment method had a significant effect (p<0.05) on all variables except moisture content. Storage time had a significant effect (p<0.05) on most of the research variables, except pH and water activity. The results of microbiological analysis showed that there was significant effect (p<0.05) of treatment between processing methods and storage time. Based on this study, nasu palekko with dry processing method has lower pH, moisture content, water activity, MDA, and trimethylamine content. Higher intensity of fat oxidation occurs in wet processing.

Service activities were conducted in the Bugel Peni II and III Joint Business Group (KUB) in Bugel Village, Kulonprogo Regency. Fishermen who join this group often do not get maximum catches because they face various obstacles, such as limited technology and unpredictable weather conditions. This community service aims to provide portable FAD innovations and determine the success of using portable FADs in fishermen's catches. Portable FADs are proposed for this service activity to provide a solution to minimize losses due to these obstacles. Portable FADs are an innovation that stimulates fish behavioral responses using sound waves with a specific frequency on an attractor, developing from the concept of conventional FADs. The implementation method begins with outreach to fishermen in the Bugel Peni II and III Joint Business Group (KUB) regarding the concept and benefits of portable FADs. Practical training was carried out on the installation and use of these tools and education regarding their positive impact on fish catches. In addition, data collection was carried out through direct observations in the field to understand fish responses to portable FADs. The positive impact of this service activity is that the application of portable FADs provides in-depth insight into the urgency of using technology to increase fish catches by fishermen. Apart from that, this service activity also provides important insight regarding the natural factors fishermen face in implementing portable FADs, such as weather uncertainty, increasingly scarce fish resources, and natural conditions, namely high waves, which are the main obstacles in achieving the expected results.
