AbstrakRusip merupakan produk fermentasi hasil perikanan yang dihasilkan oleh bakteri asam laktat yang mengandung peptida bioaktif. Penelitian ini bertujuan untuk mengetahui rendemen, kadar peptida, serta aktivitas antioksidan dan antikolesterol ekstrak rusip. Penelitian ini menggunakan dua jenis rusip, yaitu rusip A yang memiliki aktivitas antioksidan terbaik dan rusip B yang memiliki aktivitas antikolesterol terbaik didasarkan pada hasil penelitian sebelumnya. Ekstraksi dilakukan dengan metode maserasi tunggal menggunakan aquabides, dilanjutkan dengan fraksinasi berdasarkan perbedaan berat molekul. Uji antioksidan dilakukan dengan metode 2,2’-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) dan uji antikolesterol dilakukan dengan metode penghambatan aktivitas enzim HMG-KoA reduktase. Hasil penelitian memperlihatkan fraksi F1 (berat molekul > 10 kDa) memiliki rendemen yang paling tinggi baik pada rusip A maupun rusip B dengan rendemen berturut-turut sebesar 16,61% dan 14,14%. Kadar peptida tertinggi rusip A dan rusip B terdapat pada fraksi E (ekstrak utuh) yaitu masing-masing sebesar 1,22% dan 1,25%. Aktivitas antioksidan tertinggi pada rusip A terdapat pada fraksi F3 (berat molekul < 1 kDa) dengan nilai hambatan sebesar 62,90% pada dosis 1 mg/mL dan aktivitas antikolesterol tertinggi terdapat pada fraksi F2 (berat molekul 1-10 kDa) dengan nilai inhibisi sebesar 50% pada dosis 5 mg/mL. Aktivitas antikolesterol dan antioksidan fraksi rusip tersebut tergolong rendah dibanding produk fermentasi ikan lainnya. Antioxidant and Anticholesterol Activity of Rusip ExtractAbstractRusip is a fermented product which is produced by lactic acid bacteria containing bioactive peptide. The purpose of this research was to study the yield, peptide content, antioxidant and anticholesterol of rusip extract. This study used two types of rusip, i.e. rusip A which had the best antioxidant activity and rusip B that had the best anticholesterol activity based on the results of previous studies. Rusip was extracted by single maceration methode used aquabidest and continued with fractionation based on differences in molecular weight. Antioxidant assay was conducted using 2,2’-azino-bis (3-ethylbenzthiazoline-6-sulphonic acid) (ABTS) methode and anticholesterol assay by inhibition of HMG-CoA reductase enzyme methode. The result showed that F1 fraction (molecular weight > 10 kDa) had the highest yield both in the rusip A and rusip B, i.e 16.61% and 14.14% respectively. The highest peptide content of the rusip A and rusip B was obtained from E fraction (whole extract), i.e. 1.22% and 1.25% respectively. The rusip fraction with highest antioxidant activity of rusip A was F3 fraction (molecular weight < 1 kDa) that had inhibition of 62.90% (concentration of 1 mg/mL) and the highest activity of anticholesterol was F2 fraction (molecular weight 1-10 kDa) with inhibition of 50% (concentration of 5 mg/mL). The antioxidant and anticholesterol activity of the rusip extract was low ompared to other fish fermented products.
Ponggok village is one of the villages in the Klaten Regency that has an abudance of springs. This condition is used as a potential to improve the village economy. One of the strategies undertaken by the village government is to manage the spring as a means of tilapia cultivation. The management is carried out by developing community institutions through groups of fish farmers. This study aims to determine the implementation of strategies in the management of fisheries resources in Ponggok Village. This study uses a qualitative descriptive research method. Primary data mostly related to community institutions towards the utilization of fisheries resources. The selection of informants is done deliberately by considering the interests of the respondents in the management institution. Data collection is done by interview techniques, observation and documentation using tools such as interview and observation guidelines. The data analysis technique in this study uses an interaction model approach in the form of an institutional approach and the principles of co-management. The results of the study show that the strategy applied by the government in the management of fisheries resources is through institutional development using a participatory approach to decision making. The strategy has been implemented through a predetermined work program by forming a group of fish farmers shaded by Badan Usaha Milik Desa (BUMDes).
As the population of older people grows, ageing issue becomes a priority to overcome in order to facilitate well-being among older people in Indonesia. One of critical factors that contributes to well-being is living arrangement. Ageing in place is a concept that refer to the ability of older people to live safely, independently, and comfortably in their homes as long as possible. However, there are some of older people and families who experience scare resources in caregiving and housing. To overcome these issues, institutional care is provided by the government to assist older people who do not have sufficient social supports. However, transferring older people from home to institutional care are still being a debate in Indonesia. In another words, institutional care is considered taboo by most Indonesians. In addition, international literatures emphasized the important of ageing in place and regard institutional care quite opposite to ageing in place. Therefore, this literature study aims to discuss the concept of ageing in place, institutional care, and to propose the idea to integrate the two conflicting concepts in order to facilitate inclusiveness among older people. This article is also expected to contribute to facilitate well-being among older people in Indonesia.
Pemasaran mempunyai peran penting dalam pengembangan usaha perikanan. Di era yang serba digital banyak anak muda Indonesia yang tertarik membuat startup digital (Sociopreneurship) yang memanfaatkan teknologi sebagai platform telah dimanfaaatkan PT. Aruna Jaya Nuswantara untuk mengembangkan produk digital E-Commerce. Lobster yang dipasarkan dari beberapa Mini Plant PT. Aruna Indonesia, diantaranya yaitu Mini Plant Sorong, Berau, Kota baru, Balikpapan dan Kendari. Dari kelima Mini Plant tersebut, Mini Plant Kota Baru, Kalimantan Selatan merupakan Mini Plant yang paling produktif mengirimkan lobster terutama pada saat COVID-19. Tujuan penelitian yaitu untuk mempelajari, mengidentifikasi tahapan masalah dan menganalisa penyelesaian masalah penjualan lobster (Panulirus spp), dari Mini Plant Kota Baru di PT Aruna Jaya Nuswantara. Metode yang digunakan pada teknik permasalahan yaitu menentukan Key Performance Indicator, Fishbone Diagram, Analisa Root Cause dan Rencana Penerapan Intervensi. Total penjualan lobster (Panulirus spp), tingkat produktivitas dari lobster hidup sudah baik yakni diatas nilai 1 yang artinya jika kurang dari 1 adanya mengalami kerugian, Namun perlu adanya peningkatan untuk mencapai Key Performance Indicator yang telah ditetapkan, maka dari itu perlu di analisis intervensinya.
