Abstract

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.

Abstract

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.

Abstract

Massive amounts of mussel shell waste are generated and wasted from the aquaculture processing sectors, resulting in environmental pollution. This material contains chitosan as a valuable compound characterized as a non-toxic structural component with several food processing applications or medicinal applications. In this research, mussel shells were processed using different solvents concentrations in several stages: demineralization, deproteination, decolourization, and deacetylation. Our result showed that the C2 samples gained a high degree of deacetylation (31.8±0.21%) with low moisture and ash content and medium weight of yield. Further research is recommended to purify chitosan using various instrumentation and assess its bioactivity.

Abstract

Food needs in urban areas are increasing along with increasing population growth. The problem of population growth in urban areas is always followed by the construction of housing facilities. The development of housing facilities has an impact on the availability of land and water resources for fish farming and agriculture. Aquaponics technology is a combination of aquaculture and hyroponics technology in one system to optimize the function of water and space as maintenance media. Aquaponic system is a system that offers solutions related to narrow land use and limited water resources for fish and plant cultivation activities. In this community service activity, the aquaponics system was introduced to the community in the Dahanrejo area, with several activities carried out including the creation of an aquaponics unit, counseling and training given to the community on this aquaponics technique and unit. In carrying out community service activities there are several stages that need to be carried out including: location surveying, designing and testing of acuponic technology, counseling and training, monitoring and surveying. From the activities carried out, 20 people received training on how to use the land for freshwater fish cultivation and crop cultivation using aquaponics technology. In addition, an aquaponic unit was handed over to the kelurahan as a model for the existing community.

Abstract

The decrease of green mussel production in 3 years (2018 – 2020) was suspected to Pb levels on the whole organ of green mussels, which estimated to 0.7 ppm, in Banyuurip village, Ujung Pangkah, Gresik Regency. The expansion of industrial or domestic (household) activity was claimed to contribute a magnificent waste in the water. The purpose of this study was to analyze Pb levels on the whole organ of green mussles before and after the depuration. This research was implemented in Gayam, Soko Village, Glagah Sub-District, Lamongan Regency. Green mussel samples was taken from Banyuurip beach, where the green mussels culture was done. Then, 10 kg of green mussels was added to several container in size 150 L for depuration procedure. The main parameter in this research was the Pb level on the whole organ of green mussels and water media, and the other parameter was water quality (DO, pH, salinity, temperature and amonia). After performed this research, we expected to give information of depuration technology respond against Pb reduction after flushing inrecirculation system. Research used experimental method with complete random design, consist of 4 treatments and 3 repetition. P1 used as control, P2, P3, P4 (depuration method in 8, 16, and 24 h). The flushing in 24 h was removed Pb 59%, from 0.66 ppm to 0.27 ppm. As this decline, the green mussels which was cultivated by fisherman will be more safety to consume as food products. The result of this depuration with recirculation system was lower and appropriate with BPOM standardization (2009), Perikanan (DKP) No:Kep 20/Men/2004,SK Ditjen POM No. 03725/B/SK/VII/1989, which the limit of pollutan in food products was 1.5 ppm
