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

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.

Abstract

Kerang hijau adalah komoditas laut endemik perairan Indonesia yang bernilai ekonomis penting dan potensial dijadikan sebagai objek eduwisata terkait aspek biologis dan habitatnya yang terintegrasi dengan ekosistem hutan mangrove.  Desa Banyuurip memiliki potensi kerang hijau melimpah yang telah lama dibudidayakan oleh nelayan tradisional di Laut Jawa, berdekatan dengan area ekowisata Banyuurip Mangrove Center (BMC), sehingga perlu diujicobakan kerang hijau yang dibudidayakan dalam unit karamba apung sebagai objek eduwisata. Tujuan penelitian adalah menganalisis pertumbuhan dan hasil panen kerang hijau dalam karamba apung yang dioperasikan pada koordinat 06°52'18.84" LS dan 112°29'41.19" BT di Laut Jawa Desa Banyuurip Kecamatan Ujungpangkah.  Karamba apung memiliki area terang dan area gelap terkait dengan penerimaan cahaya matahari di kolom air, dimana area gelap terjadi akibat penutupan permukaan karamba apung yang diperuntukkan sebagia area catwalk agar area karamba mudah diiakses bagii siapa pun yang berkunjung ke sana.  Metode penelitian ini adalah deskriptif dan sampel diambil secara purposive random sampling.  Sampel kerang hijau dari area terang (n= 4354) dan (gelap n=2416) dianalisis aspek biometri, laju pertumbuhan, dan biomassa panen. Parameter kualitas air diukur secara berkala. Uji t (α=5%) digunakan untuk menetapkan perbedaan rerata variabel populasi dari area terang dan gelap. Aspek biometri lebar di area terang (17,69±3,99 mm) berbeda nyata (P<0.05) dari lebar di area gelap (17,14±3,76 mm), tinggi di area terang (11,75±2,86 mm) berbeda nyata (P<0.05) dari tinggi di area gelap (11,32±2,78 mm). Nilai ‘b” hubungan aspek biometri memiliki pola pertumbuhan allometric negative atau (b< 3) dimana pada area terang 2.39 dan area gelap 2.45. SGR pada area terang 1.57%/hari dan pada area gelap 1,55%/hari. Hasil panen pada area terang berkisar antara 3414–4992 g sedangkan pada area gelap 3331 – 3530 g, yang berkaitan dengan luasan dan jumlah tali kolektor di kedua area. Parameter kulitas air pada lokasi tersebut meliputi suhu 27,83±0.980C, pH 7,17±0.75 ppm, DO 6,92±0,74 mg/l, kecerahan 152±31,07 cm, dan salinitas 24,17±1,47 ppt masih dalam kondisi optimal untuk pertumbuhan kerang hijau. Berdasarkan hasil penelitian, disimpulkan bahwa hasil panen berdasarkan aspek biometri kerang hijau di area terang lebih baik dari pada di area gelap sedangkan laju pertumbuhan di area terang sama dengan di area gelap. Hasil penelitian ini diharapkan menjadi bahan rekomendasi bagi perekayasaan unit karamba apung yang diperuntukkan bagi aktivitas eduwisaata. Green mussels are endemic marine commodities in Indonesian waters that have significant economic value and potential as educational tourism objects related to their biology and habitat aspects integrated with mangrove forest ecosystems. The traditional fishermen in Banyuurip Village cultivated it many years ago in the Java Sea, adjacent to the Banyuurip Mangrove Center (BMC) ecotourism area, so it is necessary to test green mussels cultivated in floating cage units as an educational object. The study aimed to analyze the growth and yield of mussels in floating cages operated at coordinates 06°52'18.84" South Latitude and 112°29'41.19" East Longitude in the Java Sea, Banyuurip Village, Ujungpangkah District. Floating cages have bright areas and dark areas related to the reception of sunlight in the water column. Dark areas occur due to the closure of the floating cage surface, which is designated as a catwalk area so that the cage area is easily accessible to anyone. This research method is descriptive, and the sample is taken by purposive random sampling. Green mussel samples from bright (n=4354) and (dark n=2416) areas were analyzed for biometric aspects, growth rate, and harvested biomass. Air quality parameters are measured regularly. The t-test (α=5%) is used to determine the difference in the mean of the population variables from the light and dark areas. The biometric aspect of width in the bright area (17.69±3.99 mm) is significantly different (P<0.05) from the width in the dark area (17.14±3.76 mm), height in the bright area (11.75±2, 86 mm) was significantly different (P<0.05) from the height in the dark area (11.32±2.78 mm). The value of 'b' about biometric aspects has a negative allometric growth pattern or (b < 3) where the light area is 2.39 and the dark area is 2.45. SGR in bright areas is 1.57%/day and in dark areas is 1.55%/day. Yields in the light area ranged from 3414 – 4992 g, while in the dark area, it was 3331 – 3530 g, which relates to the area and the number of gathering ropes in both areas. Water quality parameters at that location include temperature 27.83 ± 0.980C, pH 7.17 ± 0.75 ppm, DO 6.92 ± 0.74 mg/l, brightness 152 ± 31.07 cm, and salinity 24.17 ± 1 .47 ppt is still in optimal conditions for the growth of mussels. Based on the study results, the yield based on biometric aspects of green mussels in bright areas is better than in dark areas, while the growth rate in bright areas is the same as in dark areas. The results of this study are expected to become recommendations for the engineering of floating cage units intended for educational activities.
