Green mussels (Perna viridis) are one of the prospective aquatic resources that can be developed into a high-value commodity. Their shells, on the other hand, are rarely used and discarded; despite the fact that the shells are contain chitosan, which can be used as a food preservative.The purpose of this study is to examine the effect of chitosan administration from green mussel shells on Sonneratia caseolaris mangrove syrup at various concentrations. The experimental design used Completely Randomized Design (CRD) with 7 treatments within 3 replications. The study lasted 30 days in order tho find the best concentration of chitosan as a preservative. The McFarland method was used to evaluate the total dissolved density (Brix), the acidity (pH), the organoleptic study (aroma and color), and the bacterial density. The following treatments were used in this study: P1 to P5 (the addition of 0.1-0.5 ml of green mussel sheel chitosan solution); P6 (the negative control or without the addition of green mussel shell chitosan solution); and P7 (the positive control with the addition of 0.1 ml sodium benzoate (C7H5NaO2) as commercial preservative). The results showed that the average value of total dissolved density P1-P7 varied between 22-22.46 (Brix); acidity (pH) of P1-P7 ranged between 2-3,1; and the organoleptic test obtained points 5 (neutral) on the aroma and color test. As a conclusion, chitosan derived from green mussel shellsP. viridis is promising agent to be utilized as a preservative in S. caseolaris mangrove syrup.

Kabupaten Lamongan merupakan salah satu sentra kegiatan budidaya ikan di Propinsi Jawa Timur. Kegiatan budidaya ikan umumnya terfokus pada usaha pembesaran ikan, baik dalam areal pertambakan maupun perkolaman, baik tawar hingga bersalinitas. Salah satu komoditas perikanan dari perairan tambak Kabupaten Lamongan adalah ikan nila. Selama tiga tahun terakhir, produktivitas hasil panen ikan nila di tambak Desa Weduni semakin hari semakin turun dikarenakan mutu ikan nila yang kurang baik. Disisi lain, pembudidayaan kerang hijau memiliki nilai ekonomis yang cukup tinggi namun usaha ini meninggalkan limbah cangkang kerang yang menumpuk dan tidak termanfaatkan. Salah satu terobosan yang dapat dilakukan adalah dengan mengekstrak kitosan dari limbah cangkang kerang hijau yang selanjutnya dapat dimanfaatkan sebagai pengaya (suplemen) pakan ikan. Pelaku usaha budidaya ikan nila umumnya merupakan masyarakat asli setempat yang mengedepankan kearifan lokal. Umumnya, keberhasilan panen bergantung pada kualitas pakan dan kondisi cuaca. Sehingga, pola budidaya ikan yang konvensional seperti ini cukup beresiko mengalami gagal panen. Pengayaan kandungan pakan ikan dapat menjadi jalan alternatif untuk meningkatkan keberhasilan usaha budidaya ikan nila. Penambahan kitosan pada pakan ikan diharapkan mampu meningkatkan imunitas, nafsu makan, serta kualitas hidup ikan sehingga dapat meningkatkan keberhasilan panen dan nilai jual ikan nila.

The high cost of shrimp or lobster feed is also a problem in the sustainability of aquaculture, even though freshwater crayfish, including eaters, require proper and relatively cheap feed selection. One source of feed that can be used as an alternative is green clams and silk worms. This study aims to determine which feed is better and more affordable for freshwater lobster seeds, so that the sustainability of cultivation can be well maintained in terms of economy, quality and quantity. The method used was descriptive comparing between the two feeds given a dose of each treatment, namely 10% of the lobster seed biomass, then analyzed using a 95% confidence level t-test. The results showed a significant effect (P <0.05), on the absolute length growth and absolute weight of freshwater lobster seeds. The absolute length of the seeds given green shellfish feed is 0.94 ± 0.38 cm and silkworm feed is 0.66 ± 0.27 cm, for the absolute weight of green shellfish feed is 5.11 ± 0.38 gr and silk worm feed 2.68 ± 0.18 gr. The best results from the two feeding treatments for freshwater lobster seeds were using green shellfish feed with an absolute weight value of 5.11 ± 0.38 gr and the absolute length is 0.94 ± 0.38 cm. So that green shellfish feed can be used as a better alternative feed for the cultivation of freshwater lobster seed enlargement.
