Abstract

Xerostomia merupakan keluhan subyektif mulut kering yang sering berhubungan dengan adanya penurunan fungsi kelenjar saliva. Penanganan pasien xerostomia dapat dilakukan dengan pemberian saliva buatan. Mukus lele memiliki karakteristik dan kemampuan dalam menggantikan fungsi saliva, sehingga dengan konsentrasi yang tepat mampu berperan sebagai lubrikan yang baik. Penelitian ini bertujuan untuk mengetahui ada tidaknya kemampuan pembasahan antara saliva manusia dengan saliva buatan yang mengandung mukus lele (Clarias batrachus) pada permukaan hidrofobik. Mukus lele (Clarias batrachus) diekstraksi kemudian diformulasikan menjadi saliva buatan dengan menambahkan 0,1% methylparaben, 0,05% EDTA, 4,69% dekstrosa, dan aqua pro-injection. Pengujian dilakukan dengan mengukur kemampuan pembasahan saliva buatan menggunakan indikator besarnya sudut kontak sampel pada permukaan hidrofobik selama 5 menit. Data yang digunakan merupakan rerata nilai sudut kontak pada kedua sisi tetesan di menit ke-0, 0,5, 1, 1,5, 2, dan 5 yang dianalisis menggunakan aplikasi ImageJ. Hasil independent sample t-test  menunjukkan sudut kontak saliva buatan mukus lele lebih kecil daripada saliva manusia (p<0,05) pada pengamatan menit ke-0, 0,5, 1, 1,5, 2, dan 5. Kemampuan pembasahan saliva buatan mukus lele memiliki perbedaan yang signifikan dibandingkan dengan saliva manusia, sehingga saliva buatan ini memberikan fungsi lubrikatif dan protektif yang tidak terlalu menyerupai saliva manusia.

Abstract

Keberadaan bakteri proteolitik pada komoditas akuakultur penting untuk dipelajari, salah satunya terkait dengan praktek budidaya ikan skala kecil di daerah pedesaan. Penelitian ini bertujuan untuk mengetahui keberadaan dan melakukan identifikasi secara molekuler bakteri proteolitik yang diisolasi dari saluran pencernaan ikan nila (Oreochromis niloticus). Sampel ikan nila diambil dari tiga unit kegiatan akuakultur yang menggunakan pakan berbeda di Kabupaten Banyumas yaitu dari Desa Pandak (dengan probiotik, pakan pellet), Desa Beji (tanpa probiotik, pakan tumbuhan) dan Desa Tambaksogra (dengan probiotik, kombinasi pakan pellet dan tumbuhan). Jumlah bakteri, proporsi bakteri proteolitik, dan indeks aktifitas proteolitik diamati dari usus bagian anterior, middle, dan posterior. Sampel isolat bakteri  proteolitik dikelompokkan berdasarkan hasil analisis restriksi 16S rDNA menggunakan software PhyElp. Bakteri dari setiap kelompok diidentifikasi berdasarkan sekuen gen 16S rDNA dengan menggunakan analisis BLAST dan analisis filogenetik. Jumlah bakteri di saluran pencernaan ikan nila dari tiga tempat relatif sama dan cenderung meningkat ke arah posterior. Hasil penelitian menunjukkan ikan nila dari Desa Pandak memiliki proporsi bakteri proteolitik yang lebih tinggi dibandingkan sampel ikan dari Desa Beji dan Tambaksogra. Nilai aktivitas bakteri proteolitik saluran pencernaan ikan nila dari Desa Pandak relatif lebih tinggi dibandingkan dari dua desa lainnya. Bakteri proteolitik dari saluran pencernaan ikan nila dapat dikelompokkan menjadi 15 kelompok berdasarkan polimorfisme hasil digesti fragment gen 16S rDNA. Sampel dari 15 kelompok tersebut memiliki sekuen 16S rDNA yang mirip dengan Pseudomonas aeruginosa (4 isolat), Plesiomonas shigelloides, Escherichia coli, Aeromonas veronii, Klebsiella variicola, Enterobacter ludwigii, Enterobacter hormaechei (2 isolat), Enterobacter cloacae, Bacillus subtilis, Bacillus amyloliquefaciens dan Bacillus sp.

Abstract

Lobster (Panulirus spp.) merupakan salah satu komoditi unggulan yang bernilai ekonomis tinggi, sehingga menjadi salah satu target tangkapan nelayan. Seiring berjalannya waktu permintaan tidak hanya untuk keperluan konsumsi saja, tetapi juga mencakup benih (Puerulus). Tingginya permintaan dan harga dikhawatirkan akan mengancam keberlanjutan sumberdaya, karena semakin memicu upaya penangkapan. Menyikapi kondisi tersebut, pemerintah membatasi ukuran penangkapan dengan mengeluarkan PERMENKP No.56/2016. Namun pada tahun 2020 aturan tersebut di ganti dengan PERMENKP No.12/2020 yang memberikan izin terhadap penangkapan Puerulus. Tujuan penelitian ini yaitu menganalisis keberlanjutan pengelolaan lobster pasca moratorium kegiatan penangkapan Puerulus di Kecamatan Cidaun Kabupaten Cianjur. Metode penelitian yang digunakan yaitu mix method dengan penentuan jumlah sampel menggunakan Slovin dengan jumlah 79 orang nelayan. Data yang terkumpul dianalisis menggunakan MDS dengan pendekatan Rapfish. Hasil penelitian menunjukan bahwa berdasarkan dimensi ekologi, sosial, teknologi serta hukum dan kelembagaan status pengelolaan sumber daya Lobster di perairan Kecamatan Cidaun Kabupaten Cianjur berada pada kategori kurang berkelanjutan, sementara berdasarkan dimensi ekonomi tergolong kategori cukup berkelanjutan.

Abstract

Blenniidae adalah famili ikan yang ditemukan di ekosistem pesisir seperti zona intertidal. Gunung Kidul memiliki banyak pantai kars dengan kesamaan dalam kondisi dan formasi geologi. Keanekagaman dan histologi Blenniidae di Gunung Kidul, terutama di Pantai Krakal, masih belum banyak dipelajari. Penelitian ini bertujuan untuk mengetahui morfometri serta struktur histologi respirasi anggota famili Blenniidae yang ditemukan di pantai Krakal. Penelitian ini dilakukan di pantai Krakal dengan metode pengambilan sampel bebas. Sampel kemudian dibawa ke Laboratorium Struktur Perkembangan Hewan untuk diukur dan dibedah. Sebanyak 3 spesies dengan masing-masing 5 sampel ditemukan di zona intertidal pantai Krakal. Dari pengamatan morfometrik, ditemukan bahwa Istiblennius edentulus dengan Istiblennius dussumeri memiliki rata-rata rasio morfometri yang berbeda sementara Istiblennius lineatus memiliki rata-rata rasio morfometri yang sama dengan Istiblennius  edentulus dan Istiblennius dussumeri. Hasil pengamatan struktur histologis insang tidak menunjukan adanya perbedaan jaringan penyusun insang antar spesies ikan, yang tersusun oleh lamella primer (1), lamella sekunder (2), sel eritrosit (3), sel pilar (4), sel epitel (5), sel mukus (6), dan sel klorit (7). Struktur insang tiap spesies ikan ini sesuai dengan kondisi habitat berupa udara terbuka sehingga dapat memperluas area respirasi dan menyimpan air di dalam insang.

Abstract

A seaweed storage device in the form of a bunker has been developed by the Indonesian Research Institute for Fisheries Postharvest Mechanization. This study aimed to compare the quality of dried E. cottonii stored in the seaweed storage device and stored in the sacks placed in the room. Based on SNI 2690:2015, dried E. cottonii quality can be determined from its moisture content, impurities, Clean Anhydrous Weed (CAW), and Total Yeast and Mold Counts (TYMC). Moisture content was measured according to CAW, and contaminants were measured respectively according to SNI 01-2354.2-2-2006, SNI 8168:2015, and SNI 8169:2015. The results showed that moisture content of the seaweed stored in the bunker decreased by 27.17%, and that stored in the sacks decreased by 14.77%, signing a more significant weight loss during storage in the bunker. However, seaweed stored in the bunker has lower impurities (1.70±0.13 vs 1.84±0.13%), higher CAW (40.42±2.45 vs 38.75±2.45%), and TYMC (450±70 vs 2500±115.33 cfu/g).

Abstract

This study were aims to test the growth performance of tilapia (Oreochromis niloticus) seeds fed with different quantities of the symbiont, consisting of a probiotic and a prebiotic, such as B. subtilis and banana flour, respectively. This study employs an experimental approach with a completely randomized design (CRD). Furthermore, artificial feeds were prepared as various treatments, consisting of B. subtilis and banana flour concentrations. They include treatment A, which does not contain B. subtilis and banana flour, and also treatment B, C, and D, which consists of B. subtilis at concentrations of 105 CFU/mL, 107 CFU/mL, and 109 CFU/mL, respectively, as well as 1% banana flour. The results obtained showed that weight gain (WG) and specific growth rate SGR were significantly different in treatment B but the survival rate (SR), food conversion rasio (FCR), hepatosomatic index (HSI), and condition factor (K) did not show significant results. Meanwhile, somatic digestive index (DSI) showed a significant difference with treatment A, C, and D, but not with treatment B. However, treatment B showed a relatively better performance based on the SR, FCR, and WG at 96.67 %, 1.05 %, and 3.49 %, respectively.

Abstract

A successful capture fisheries business requires a fishing port with excellent facilities. This study, therefore, aims to analyze the current facility utilization rate of Pondokdadap, The Coastal Fishing Port (CFP) and formulate a suitable development strategy. The study was conducted using a descriptive survey from January to April 2021. Twenty-four respondents comprising 11 CFP (Coastal Fishing Port) and FAP (Fish Auction Place) employees and 13 fishers and fish traders were obtained using the inclusion criteria. Primary data was collected through structured interviews based on a questionnaire, while secondary data were obtained through literature reviews on books, articles, and journals related to research. Subsequently, an analysis of facility utilization at CFP Pondokdadap was carried out, while a SWOT analysis was performed on the proposed alternative development strategy. Based on the results, the existing physical condition of the facilities is satisfactory, with varying utilization rates. However, the Government and the CFP Pondokdadap management are encouraged to implement other development strategies, for instance, strengthening fisheries competitiveness by maintaining fish quality, optimizing Sempu Island as a natural breakwater and marine aquaculture fisheries, developing a fishery information system, building supporting facilities at CFP Pondokdadap, as well as improving the quality of human resources, apparatus, and fishing communities at CFP Pondokdadap.

Abstract

Cimanuk River is the second longest river in West Java, flowing from Garut to Indramayu. One of the sub-watersheds of the Cimanuk River is the Cipeles River in Sumedang and Majalengka. Genggehek (Mystacoleucus marginatus) is a type of native fish (indigenous) found in these two rivers. The purpose of the study was to determine growth performance including size distribution, growth pattern and condition factors. The research was conducted by conducting a survey in the dry season in September 2020. The method used was the fisheries biology method. Measurement and data analysis were conducted at the Aquatic Resources Laboratory of Padjadjaran University. The number of fish caught was 231 with a length range of 45 mm - 116 mm and a weight range of 1,1 g – 37,4 g. The growth performance of fish living in Cimanuk River was different from that living in Cipeles River. In Cimanuk River had positive allometric with regression equation W = 4.10-6 L3.2171 and W = 6.10-6 L3.1449. Weight growth was faster than length, condition factor was between 1,27 and 1,33. The growth performance of fish growing in the Cipeles River had a negative allometric growth pattern. The length growth was faster than the weight with the regression equation W = 7.10-4 L2.1182 and W = 7.10-5 L 2.7434, R2 = 0.36 and 0.92, condition factor K = 1.01 and 1.35.

Abstract

This study provides a relevant examination of fish consumption among Indonesian youth; it contributes to their perception of fish quality assurance. A cross-sectional sample of Indonesian youth scholars between 17 and 26 years old (n = 1.163) responded to an online questionnaire validly from February to March 2021. Structural equation modelling was used to estimate the direction and strength of relationships between variables. The results demonstrate that fish availability, health involvement, fish consumption in childhood, sensory beliefs, and price correlated significantly with fish consumption among Indonesian youth, but that relationship was mediated by attitude to consume fish. Social pressure also has a significant correlation to fish consumption among Indonesian youth. Meanwhile, we found that Indonesian youth's perception of fish quality assurance negatively moderates the relationship between fish and fish consumption. This perception of fish quality assurance is likely not to affect the real-world relationship between the desire to consume fish and fish consumption. Understanding the role different variables play in their fish consumption habits may provide helpful insights for the government to develop strategies for increasing the final goal, which is the intake of fish among young consumers.

Abstract

Fishery products are a high source of nutrients, especially fatty acids. The smoking technology with liquid smoke is being developed to preserve fishery products. With this processing, fish are expected to be more durable and have better nutritional content, especially polyunsaturated fatty acids (PUFA), needed in the body. For this reason, research has been carried out to see the impact of fish processing with liquid smoke technology on the fatty acid profile of smoked Indian scad. The method used is the experimental method using coconut shell liquid smoke and samples of fresh and smoked Indian scad. The results showed that the fatty acid profile of fresh and smoked Indian scad contained 27 types of fatty acids consisting of 11 saturated fatty acids and 16 unsaturated fatty acids. The content of polyunsaturated fatty acids (PUFA) in fresh and smoked Indian scad is greater than the content of saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA). The high ratio of PUFA-ω3/PUFA-ω6 and the low value of Index of Atherogenic (IA) and Index of Thrombogenic (IT) of fresh and smoked Indian scad treated with coconut shell liquid smoke indicate the quality of fish fat is very good for consumption which is beneficial for health.
