Abstract

Fasting is one strategy to overcome the problem by giving the minimum possible amount of feed but the growth of the fish is not hampered. Fasting also means feed with a predetermined time interval in the hope that the fish can experience an increase in appetite after the fish are fasted. This study aims to determine the fisting effect of tilapia and feed efficiency et growth which fasting is the best to do. The research method used a simple completely randomized design with four treatments and two repetitions each, namely feed without fasting (treatment A), one day of fasting one day of feed (treatment B), one day fasting two days of feed (treatment C) and one day of fasting and three days of feed (treatment D). Fish were to eating three times a day at 08.00, 12.00, 17.00 at satiation. Fish seeds were given pellet feed as much as 3% of body weight. The results of analysis of variance test showed that fish feeding had no significant effect (P<0.05) at growth in weight and length and feed efficiency but significantly (P>0.05) at survival rate. The results showed that the best weight and length growth values in tilapia were found in treatment D with an average weight growth value of 12.20±0.22 gram, length 2.41±0.24 cm. The best feed efficiency was found in treatment B, which was 60.83±6.60% and the best survival was found in treatment A a with an average value of 86.67±0,00%.

Abstract

The aims of this service is to increase the knowledge and skills of fish traders in handling yellowfin tuna by bulking using crushed ice cubes without mixing with water in the box and controlling the quality of fish using an organoleptic table score sheet during cooling process for three days. The method used is the early preparation of the training by conducting a pretest, delivering material and discussion, observing the quality assessment of fish by describing the changes that occur during storage with an explanation of the application theory as well as the implementation of practicum, interviews and evaluation of the final results of the activity by conducting a post-test. The results of the community service implementation attended by 15 participants from fish traders, about 48% was good in understanding and mastering the knowledge of refrigeration fish, about 28% was sufficient in accepting the knowledge and 24% was lacking in understanding the knowledge of refrigeration fish. The average value after given the training is 64.1.

Abstract

The waters in Youtefa Bay have degradation due to the transition from mangrove areas to industrial sites, housing, bridge construction and household waste disposal. Water degradation has indirectly affected the growth of plankton. Plankton consists of phytoplankton which is the primary producer of the food chain so that it is utilized by zooplankton as the first consumer. The aim of this study was to determine the abundance and diversity of phytoplankton and zooplankton. This research was conducted during June-August 2019, the method used purposive sampling. Samples were obtained from 6 observation stations. The results showed there is 28 species of phytoplankton (∑160,000 ind/L) and 15 species of Zooplankton (∑ 84,200 ind/L). The diversity index of Phytoplankton is ranging from 1-2.21; Dominance (D) 0.17-0.4 and similarity (E) 0.59-1, while for zooplankton diversity (H’) ranges from 0.97-1.39; Domination (D) 0.07-0.42 and similarity (E) 0.59-1. The Diversity Index shows that the waters of Youtefa Bay have moderate diversity. The similarity between genera is relatively same. The Dominance index value during the observation was seen <0.5 or close to 0, this means that in the community that there was no genus that was extremely dominating the other genera.

Abstract

Ikan tuna sirip kuning memiliki kandungan protein tinggi berkisar antara 22,6-26,2 gr/100 gr daging dan lemak yang rendah berkisar antara 0,2-2,7 gr/100 gr daging. Minimnya pengetahuan masyarakat nelayan tentang manfaat kandungan gizi ikan dan cara pengolahan daging ikan tuna menjadi produk dendeng giling manis. Dengan demikian maka perlu dilakukan pelatihan pengolahan daging ikan tuna sirip kuning segar disubtitusi jantung pisang kepok dan bumbu-bumbu menjadi dendeng giling manis dengan mutu organoleptik baik. Metode yang digunakan adalah penyampaian materi dan diskusi, melakukan pre-test, praktek pembuatan dendeng, pegujian mutu organoleptik, pengemasan produk serta evaluasi hasil akhir dengan dilakukan post-test. Hasil pre-test menunjukkan 85% peserta kurang memahami tentang produk dendeng sedangkan hasil post-test sekitar 92% peserta paham atas teori pembuatan dendeng giling manis. Kesimpulan pengabdian adalah pencampuran komposisi tepung tapioka, gula merah dan bumbu perlu diperhitungkan dengan baik karena berpengaruh pada tekstur, kenampakan, rasa dan bau dendeng serta ketebalan dendeng 3 mm adalah terbaik.
