Landak laut (sea urchin) merupakan salah satu produk sumber daya perikanan penting karena telurnya memiliki nilai ekonomis dan gizi yang baik untuk kesehatan. Desa Kotajin merupakan wilayah pesisir di Kabupaten Gorontalo Utara yang memiliki potensi yang cukup besar terhadap perikanan landak laut. Sayangnya, potensi tersebut belum dimanfaatkan dengan baik karena minimnya informasi dan pengetahuan tentang pengolahan telur landak laut menjadi penganan. Sejalan dengan itu, pemerintah lokal terus mengupayakan dan menghadirkan diversifikasi dari penganan baru yang bergizi dan bernilai ekonomis tinggi untuk mendorong peningkatan gizi dan perekonomian (pendapatan) masyarakat pesisir. Pengabdian ini dilaksanakan di Desa Kotajin pada tanggal 26–27 April 2019. Tujuan dari kegiatan ini adalah untuk memberikan pengetahuan kepada masyarakat Desa Kotajin tentang cara pembuatan bakso dari telur landak laut. Hasil dari kegiatan pelatihan ini adalah produk bakso dari telur landak laut yang siap untuk dikonsumsi atau dipasarkan kepada konsumen lokal

This research was composed to identify the effect of different light intensities on the growth of Chlorella sp, as well as the optimal amount of light to improve said growth. This experimental research employed completely randomized design, with 5 treatments of different light intensities; A (3400 lux), B (4400 lux), C (5400 lux), D (6400 lux) and E (7400 lux) with 4 replications for each treatment. Based on the ANOVA, the findings revealed the different effects of the treatments (p

The demand for Gracillaria commodities continues to increase for food, medicines, and beauty ingredients. These conditions encourage the cultivation of this commodity continues to proliferate. Because of that, availability of Gracillaria sp seeds is available both in quantity and quality. One effort that can be done in handling the Gracillaria sp spores through environmental engineering. One such factor is fisheries salinity. The difference in salinity supports the increase in Gracillaria spores so that it affects spore growth. The aim of the study was to study the growth of Gracillaria spores cultured on different salinity media. The method used is a laboratory experiment method with a completely randomized trial design (CRD) with forty salinity preparations (23 ppt, 26 ppt, 29 ppt, and 32 ppt) and is repeated three times. The resulting data were then analyzed by analysis of variance. The results showed the highest spore growth at 23 ppt salinity with the number of spores (560.9 Ind / cm2), then 26 ppt salinity (438.8 Ind / cm2), then 32 ppt salinity (429.9 Ind / cm2) and low in salinity 29 with the number of spores (277.8 Ind / cm2). Fingerprint analysis showed that each evaluation results were not significantly different.
