Abstract

AbstractThe processing of alkali treated cottonii is an alternative to increase the value of Indonesian seaweed. One type of seaweed used is the type of Eucheuma cottonii. The purpose of this study was to: (1) find an alternative replacement for KOH alkali solvent with NaOH as an alkali solvent that was effective in the treatment of alkali treated cottonii. (2) analyze the effect of alkali NaOH treatment, temperature and extraction time on physical quality and yield of alkali treated cottonii, (3) determine the best method of extraction process. This research was carried out by a treatment method consisting of 2 NaOH concentrations 6% and 8%, 70° C and 80° C and 15 minutes and 30 minutes soaking time. Seaweed water content used is 35%. Seaweed was weighed, washed, immersed in NaOH solution in certain temperatures and soaking times. The seweed was dried until 9% water content and then cut to 2-3 cm length. Then physical quality of alkali treated conttoni was measured and the yield was determined. This research was repeated 3 times to obtain 24 experimental units. The range of yields is 27.33-34.00%. The range of gel strength values is equal to 195.70-402.56 g/cm2. The range of viscosity values obtained was 4.39-31.72 cP. Samples showing the best quality were obtained from alkali treated cottonii samples extracted using 8% NaOH concentration, 800C temperature and 30 minutes extraction time fulfilling the quality standards set by FAO and BSN.AbstrakPengolahan alkali treated cottonii merupakan salah satu alternatif untuk meningkatkan nilai rumput laut Indonesia.

Abstract

Kuwe (Caranx sp.) is a captured fishery commodity in the Sangihe Islands. The abundant catch of fish makes it difficult for fishermen to market because the local market in the Sangihe Islands cannot absorb it, and there is no cold storage with a large capacity to maintain the quality of fish. One of the ways to increase the durability is if the production of kuwe fish is abundant, namely by the dry salting method. The dry salting technique is relatively straightforward, so the community can apply it. This study aimed to observe the sensory characteristics and moisture content of salted kuwe fish products using the dry salting method. The research method was cleaning and fileting the kuwe fish meat, then dry salting with a salt concentration of 10%, 15%, and 20%, and drying in the sun. The results showed that the sensory test for salted fish appearance, aroma, taste, and texture was best at 15% salt concentration, with panelist values of 8.65, 8.20, 7.95, and 8.50 (respectively). The water content of salted fish at a salt concentration of 15% is 28.20%. The sensory characteristics and water content of salted kuwe fish wih salt concentration of 15% have complied with SNI 8273:2016, namely a minimum of 7 and a maximum of 40%.

Abstract

Pengolahan ikan asap di kampung Petta masih tradisional, dimana produk yang dihasilkan memiliki mutu yang selalu berbeda, serta umur simpan yang relatif pendek. Selain itu, pengasapan tradisonal dapat menyebabkan polusi lingkungan akibat asap yang dikeluarkan. Solusi yang tepat untuk mengatasi masalah tersebut adalah teknologi Pengasapan Asap Cair. Teknologi ini sudah digunakan di beberapa tempat sebagai penganti pengasapan tradisional tetapi di Sangihe teknologi ini belum dikenal oleh masyarakat pengolah ikan asap. Tujuan dari pengabdian ini ialah memperkenalkan asap cair, melatih pengolah ikan asap untuk melakukan pengasapan ikan menggunakan asap cair, dan melatih cara pengemasan ikan asap yang tepat. Metode pelaksanaannya meliputi: survei untuk mendapatkan kelompok pengolah ikan yang sudah pernah berusaha dan membicarakan persiapan penerapan teknologi bersama ketua kelompok dan pemerintah setempat, penyuluhan dan pelatihan pengolahan ikan asap dengan asap cair serta cara pengemasan vakum, pemberian bantuan alat, pendampingan, dan evaluasi. Sebelum praktek pengolahan ikan asap cair, kelompok diberi pemahaman tentang sanitasi, higienis, dan good manufacturing practices (GMP), untuk menambah pengetahuan kelompok pengolah. Hasil yang diperoleh menunjukkan bahwa kelompok pengolah “Berkat” dan kelompok “Petta” sangat menerima teknologi yang diberikan, dan dapat melakukan sendiri karena teknologinya sederhana, waktu pengolahan lebih singkat, mutu hasil lebih baik, higienis, dan mudah dilakukan. Berdasarkan hasil pengabdian maka dapat disimpulkan bahwa materi dan pelatihan yang diberikan dapat diterima dengan baik oleh kelompok masyarakat. Walaupun demikian, masih perlu dilakukan penambahan fasilitas yaitu alat pembuat asap cair untuk melengkapi alat pengolahan yang sudah diberikan. Smoked fish processing in Petta village remains traditional to this day charaterized by products of varyiing quality and relatively shortlived. In addition, traditional fish smoking poses health and environmental threats due to the released smoke. The right solution to solve this problem includes the application of liquid smoked technology. This technology has been well practized in several places to replace traditional smoking methods. However, it has been barely recognized by the smoked fish processors in Sangihe Islands. The objective of this training and fisheries advisory services were to introduce liquid smoke technology, to train smoked fish processors to smoke fish using liquid smoke, and to train the fish processors the proper way to pack smoked fish. The implementations of this program included (1) survey on the existing fish processing groups in Petta, (2) discussion about the introduced technology and transfer knowledge with the group leader and the local government, (3) training and practices on liquid smoke processing techniques, of vacum packaging technique and provison of equipments, assistance, and evaluation. Before practice sessions, the group was introduced to sanitation, hygiene, and good manufacturing practices (GMP), to increase their knowledge on the liquid fish processing. The results strongly indicated that the fish processing group "Berkat" and group “Petta” have well addopted the fish processig technology and could apply it themselves because the technology was simple, the processing time was shorter, and the quality of the final product was better, more hygienic and more practical. The training and fisheries advisory sercives were warm wellcomed by the community group. However, it is still necessary to add another liquid smoke production equipments to complement the current fish processing equipment.

Abstract

Masalah utama yang sering dihadapi oleh pengolah ikan asap “Kelompok Berkat” di kampung Petta adalah produk yang dihasilkan tidak dapat bertahan lama atau memiliki umur simpan yang rendah yaitu hanya 3 hari. Hal ini disebabkan karena produk tersebut belum dikemas sehingga produk mudah dihinggapi lalat dan kontaminan lainnya baik dari pekerja maupun peralatan yang digunakan. Keadaan ini menyebabkan nilai jual produk rendah, dan makin lama disimpan harganya makin menurun. Karena itu dirasa sangat perlu dilakukan penyuluhan dan pelatihan tentang cara pengemasan produk ikan asap. Tujuan dari pengabdian ini ialah melakukan penyuluhan tentang 1. fungsi wadah kemasan untuk menjaga kualitas, keamanan, dan masa simpan produk serta menambah daya tarik produk 2. memperkenalkan jenis-jenis wadah kemasan, dan 3. pemasaran produk yg sudah dikemas secara online berbasis media sosial. Tahapan pelaksanaannya meliputi: survey, penyuluhan dan pelatihan tentang pengemasan produk, pemberian bantuan, pendampingan dan evaluasi. Pemberian materi pengemasan diikuti dengan baik oleh kelompok berkat. Kelompok sangat antusias untuk menerima materi yang diberikan. Bantuan yang diberikan serta demo penggunaan alat vakum sealer diikuti dengan baik dan benar oleh kelompok. Kegiatan ini juga telah dipublikasikan pada media online (sastalpos.com). The main problem that is often faced by the "kelompok Berkat" smoked fish processor in Petta village is that their products cannot last long or has a short shelf life of only 3 days. This is because the product has not been packaged so that the product is easily infested by flies and other contaminants from both the workers and the equipment used. This situation causes the selling value of the product to be low, and the longer it is stored, the lower the price. Therefore, it is necessary to conduct training on how to package smoked fish products. The purpose of this service is to provide training about 1. the function of packaging containers to maintain product quality, safety, and shelf life and increase product attractiveness 2. introduce types of packaging containers, and 3. marketing products that have been packaged by online based on social media. The stages of implementation include: surveys, counseling and training on product packaging, providing assistance, mentoring and evaluation. The distribution of packaging materials was well followed by the kelompok Berkat. The group was very enthusiastic to receive the material given. The assistance provided as well as a demonstration of the use of the vacuum sealer tool were followed properly and correctly by the group. This activity has also been published on online media (sastalpos.com).

Abstract

Vibrio parahaemolyticus is a bacterium found in estuaries and marine and is a pathogenic bacterium that harms human health. Vibrio parahaemolyticus can contaminate fishery products and potentially contaminate lobster products in North Sulawesi. This study was conducted to determine the presence of V. parahaemolyticus in lobsters collected in two shelters in North Sulawesi. This study also serves as a monitoring function and a means of information on the presence of V. parahaemolyticus. The samples used were lobsters (Panulirus sp.) taken from Malalayang and Tuminting shelters in North Sulawesi. Observations in this study include total bacteria, total Vibrio, and identified V. parahaemolyticus. Isolates of V. parahaemolyticus were characterized by their growth at different temperatures (5, 37, 43 oC); pH (5 - 9); and concentrations of NaCl (0, 1, 3, 5%). The results show total plates for lobster meat from Malalayang 4.3×104 ‒ 1.0×105 CFU/g, while from Tuminting shelter 1.4×104 ‒ 3.9×104 CFU/g. The total plate on lobster gills from Malalayang is 6.2×104 ‒ 1.2×105 CFU/g, while from Tuminting shelter 2.0×104 ‒ 6.7×104 CFU/g. Total Vibrio in lobster meat from Malalayang 6.2×103 ‒ 1.4×104 CFU/g, while from Tuminting shelter 5.2×103 ‒ 7.9×103 CFU/g. Total Vibrio in lobster gills from Malalayang 8.5×103 ‒ 4.6×104 CFU/g, while from Tuminting shelter 7.8×103 ‒ 9.5×103 CFU/g. The Gram staining analysis obtained 96 isolate strains with Gram-negative rods, and 42 strains showed characteristics as V. parahaemolyticus based on the biochemical assay. Vibrio parahaemolyticus can grow optimally at 37°C, pH 7‒8, and NaCl concentration 3‒5%.
