Abstract

This study was to determine the functional properties of fish protein hydrolysis produced from tilapia frame. This study used a factorial design where the first factor was different types of proteolytic enzymes (E1 = bromelain, E2 = papain) and the second factor was different hydrolysis time (T1 = 5 hours, T2 = 6 hours) and was carried out with 3 replications. The results of the analysis showed that the different types of enzymes and hydrolysis time had a significant difference on the yield, degree of hydrolysis, proximate, viscosity, and protein solubility. This product has the potential to be used as food additives that can give special function properties so further research needs to be carried out to investigate these special functional properties for health and reduce the fat content that can affect the self-life product.Keywords: Functional properties; Protein hydrolysis; Nile tilapia frame

Abstract

Segara Anakan Lagoon is a unique and distinctive area where most of the ecosystem is dominated by mangrove ecosystems. Some fauna make the ecosystem as a place for feeding ground, nursery ground and spawning ground for example macrozoobenthos. Its sessile nature makes the biota used as a bioindicator of an area. The Segara Anakan mangrove forest is currently under pressure due to the process of sedimentation and conversion of functions by residents. Therefore, this study aims to determine the interaction between the abundance of macrozoobenthos with environmental conditions. The research was carried out in July-September 2021 at the Segara Anakan Lagoon, Cilacap. The sampling method used is the Sample Survey Method with three stations determined purposively by describing different habitat conditions. Sampling was carried out on a monthly and the data obtained were analyzed by PCA. The results showed that the highest abundance of macrobenthos was found in the western part of the Segara Anakan mangrove forest. The value of macrozoobenthos abundance is influenced by TSS related to food availability. Furthermore, the quality of water and soil is still in accordance with the quality standards of marine life.Keywords: Environmental Characteristics; Macrozoobenthos; Mangrove; Segara Anakan

Abstract

Abstract. The presence of introduced fish populations in the Penjalin Reservoir is increasing, one of the dominant ones being caught is Marsela (Parachromis managuensis). It is feared that this fish population will continue to increase and will have a negative impact on other organisms, especially native fish communities. This study aims to determine the eating habits of Marsela fish, the composition of the type of food and its relationship to the abundance of plankton in the waters. This research was conducted in September-October 2018. The method used was CPUE with a sampling technique that is Simple Random Sampling. Sampling of fish in one day is done 6 times, namely at 05:00, 11:00, 17:30, 21:00, 00:00, and 03:00. Fish samples obtained are then grouped according to length and then an analysis of the contents of the stomach. The results showed that in the Penjalin Reservoir the percentage of phytoplankton presence was 96% with the highest abundance found in the Bacillariophyta group. Marsela is an omnivorous fish with popular foods are Chlorophyta and Charophyta. However, in adulthood Marsela fish also eat animals.Keywords: Marsela Fish (Parachromis managuensis), Fish Eating Habits, Penjalin Reservoir

Abstract

Di dalam dunia pendidikan literasi menjadi hal yang sangat penting terutma untuk anak sekolah. Hal ini tujuannya untuk membiasakan anak dalam budaya literasi dimanapun mereka berada. Story telling merupakan cara yang dilakukan untuk menyampaikan suatu cerita kepada pendenga, baik itu dalam bentuk kata-kata, gambar, foto maupun suara. Dalam hal ini story telling sering digunakan dalam proses belajar mengajar utamanya pada tingkat pemula atau anak-anak. Banyak anak-anak sekarang lebih memilih game dalam gadgetnya daripada membaca informasi yang penting terkait belajarnya di sekolah. Kegiatan pengabdian masyarakat ini berupa pendampingan kepada anak-anak untuk diajak melihat dan mendengarkan cerita atau dongeng dengan teknik story telling dengan tujuan meningkatkan budaya literasi mereka. Pada Kegiatan pendampingan ini pertama dibuka dengan pengenalan tentang budaya literasi. Meningkatkan budaya literasi di kalangan anak-anak sangat penting, selain membaca literasi dapat dilakukan juga dengan mendengar dan menyimak sehingga dapat mengetahui pesan yang tersirat dari cerita.
