Indonesia as a country that has abundant natural resources, especially waters, causes the fishery sector to become one of the sectors with great potential in development. One of the efforts to improve the human resources of coastal communities is to form institutions at the farmer level, but there is a lack of insight and knowledge about the function of farmer institutions as a forum for the organization. The purpose of this community service is to increase and increase knowledge for the community about the importance of institutions in managing businesses in the fisheries sector, especially in investing. The method used by explaining directly or presenting to community groups who attended the counseling with participants was the MAPAN group from Degayu Village, Pekalongan City with 25 members. The result was that 80% of participants were able to capture knowledge about the importance of institutions for developing fishery businesses after being given counseling and the community was able to compile data on investment in institutions that were formed after receiving counseling.Â Keywords: Organization, Investment, Society

The use of pineapple fiber is still not optimal and has the potential to be used as a reinforcing material for hybrid composite materials which are expected to get higher composite material strength values. The aim of the research was to determine the dampening effect of NaOH solution on the mechanical and physical properties of pineapple fibrous composites. The research was conducted during the day at the Muhammadiyah University of Semarang (UNIMUS). The research stage is making test samples with molds according to ASTM D638 and ASTM D790 standards by pouring using Yukalac BQTN Polyester Resin. The resulting mold is then mixed with a catalyst and the pineapple fiber is applied in random directions. Tests are carried out mechanically, namely tensile and bending. The test results were then taken with macro photos. The NaOH solution concentration was given starting from 0%, 5%, 10%, and 15% with soaking for 24 hours. The results of the research were that the tensile test produced the largest tensile strength value for the 10% concentration specimen at 24.20 Mpa, while the largest elastic modulus value at the 5% concentration was 415.467 Mpa. In the flexural test, the highest value was produced for the 5% concentration specimen at 1.09 Mpa and the highest elastic modulus value at the 15% concentration was 16,350 Mpa.

The flood disaster in the coastal area of Pekalongan City resulted in stagnant water, thus impacting the livelihoods of the community previously. The adaptation that has been made to deal with these conditions is by cultivating saline tilapia. Feed is the most important factor in supporting the growth of saline tilapia production. However, research on feed quality and frequency that has been carried out for tilapia production has not been optimal in obtaining the results obtained. This study aims to determine the effect of different feeding rates on growth performance, feed utilization and survival rate of tilapia reared in stagnant brackish water. The study consisted of feeding rates of 3%, 5%, 7% and 9% with three replications, and parameters were observed every seven days. Based on the research results it is known that the optimal feeding rate in saline tilapia culture ranges from 6.67% - 7% based on growth parameters. Although the other parameters do not show the same feeding rate as the growth parameter, these parameters are still in a good range for saline tilapia culture.

Sungai Sengkarang merupakan kawasan ekosistem hayati terpadu yang berperan penting dalam menjaga keseimbangan status sumber daya ikan di Daerah Aliran Sungai Pekalongan. Tujuan dari penelitian ini adalah untuk mengidentifikasi karakteristik ekosistem Sungai Sengkareng, menganalisis permasalahan pemanfaatan, dan menganalisis strategi pengelolaan Sungai Sengkarang. Metode penelitian yang digunakan dalam penelitian ini adalah deskriptif kualitatif dengan pengambilan data secara terstruktur untuk menjawab tujuan penelitian. Berdasarkan kondisi ekologi, Sungai Sengkarang masih memiliki kondisi perairan yang cukup baik untuk dapat digunakan sebagai habitat ikan liar. Meskipun ekosistem perairan Sungai Sengkarang memiliki nilai biodiversitas yang beragam, tetapi kegiatan ekploitasi dari aktifitas manusia dirasakan dapat mengancam kelestarian sumber daya alam di sana. Adapun permasalahan yang ada di sepanjang DAS Sungai Sengkarang diantaranya adalah terjadinya pencemaran lingkungan perairan, penutupan kanal air sungai, penangkapan liar, penurunan muka tanah, dan perhatian masyarakat sekitar yang minim. Selain itu, keberadaan populasi ikan di Sungai Sengkarang juga mulai menurun dalam beberapa tahun terakhir akibat adanya eksploitasi penangkapan sumber daya ikan dan pencemaran perairan akibat kontaminasi limbah batik dan textil. Untuk menjaga supaya ekosistem hayati dan sumber daya ikan di perairan Sungai Sengkarang dapat pulih kembali maka diperlukan upaya-upaya sebagai berikut: 1) pengembangan suaka perairan; 2) rehabilitasi sungai;3) restocking ikan; dan 4) pengembangan sistem co-management dan beberapa strategi lain yang relevan secara terintegrasi. Title: Sustainable Strategy for Management of Fish Resources in Sengkarang River, Pekalongan Regency, Central Java The Sengkarang River is the longest river in Pekalongan waters. Aside from being a natural fish habitat, the Sengkarang River is also used as a buffer for biological ecosystems in the waters of Pekalongan City and Regency. The purpose of this study was to determine the fish resources status in the Sengakarang River and efforts to manage them. The method used in this research is descriptive qualitative with structured data collection to answer the research objectives Based on the water quality conditions, the Sengkarang River water description still has good enough conditions to be used as wild fish habitat. Even though the waters of the Sengkarang River have diverse biodiversity values, exploitation from human activities is felt to threaten the preservation of natural resources there. The problems that exist along the Sengkarang River watershed include pollution of the aquatic environment, closure of river water canals, illegal fishing, land subsidence, and minimal attention from the local community. Apart from that, the existence of fish populations in the Sengkarang River has also begun to decline in recent years due to exploitation of fish resources and water pollution due to contamination of batik and textile waste. In order to keep the biological ecosystem and fish resources in the waters of the Sengkarang River recovering, the following efforts are needed: 1.) development of water reserves, 2.) river rehabilitation, 3.) fish restocking, and 4.) development of a co-management system and strategic related option is an integrated manner.
