Abstract

Tingginya permintaan akan sumberdaya rajungan serta akibat dari kondisi open access akan menimbulkan dampak negatif yang mengarah ketidak efisiensi secara penangkapan maupun ekonomi. Langkah dalam pengelolaan perikanan agar tetap berkelanjutan dan memperoleh manfaat ekonomi secara optimal adalah dengan perlu memperhatikan hubungan antara upaya penangkapan berdasarkan aspek biologi dan ekonomi. Penelitian ini bertujuan untuk mengetahui potensi dan menentukan tingkat pengelolaan sumberdaya rajungan (Portunus pelagicus) di perairan Provinsi Kepulauan Bangka Belitung. Metode penelitian menggunakan metode deskriptif dengan analisis kuantitatif pendekatan model bioekonomi model Gordon-Schaefer. Hasil penelitian menunjukkan potensi sumberdaya rajungan pada tahun 2014-2018 mengalami penurunan produksi. Produksi tertinggi terjadi pada tahun 2014 sebesar 9.685 kg sedangkan produksi terendah terjadi pada tahun 2015 sebesar 6.049 kg. Estimasi bioekonomi model Gordon-Schaefer menunjukkan bahwa produksi sumberdaya rajungan pada kondisi MSY tahun 2014-2016 diindikasikan pernah mengalami biological overfishing dikarenakan upaya penangkapan yang berlebihan. Pada kondisi MEY menunjukkan bahwa produksi sumberdaya rajungan pada tahun 2014,2015,2014,2018 diindikasikan pernah mengalami economic overfishing. Jika pada kondisi OAE menunjukkan bahwa pemanfaatan sumberdaya rajungan sudah tidak efisien dan menimbulkan kerugian yang besar diantaranya aspek biologi, lingkungan, sosial dan ekonomi. Pengelolaan yang dapat dilakukan adalah 1) Pengaturan upaya penangkapan yakni pengaturan jumlah trip dan pengaturan pola dan musim penangkapan. 2) Kebijakan dalam pengaturan harga dalam biaya operasional nelayan. The high demand for blue swimming crab resources and the consequences of open access conditions will have a negative impact that leads to inefficiency both technically and economically. The step in managing the economy in order to remain sustainable and obtain optimal benefits is to pay attention to the relationship between implementation efforts based on biological and economic aspects. This study aims to determine the potential and determination of blue swimming crab (Portunus pelagicus) resource in the Waters of Bangka Belitung Archipelago Province. The research method uses a descriptive method with quantitative analysis of the Gordon-Schaefer bioeconomic model approach. The results showed that the potential of blue swimming crab resources in 2014-2018 decreased in production. The highest production occurred in 2014 at 9,685 kg while the lowest production occurred in 2015 at 6,049 kg. The estimation of the Gordon-Schaefer bioeconomic model shows that the production of blue swimming crab under MSY conditions in 2014-2016 is thought to have occurred biologically overfishing due to excessive effort. MEY conditions indicate that production in 2014,2015,2014,2018 is said to have experienced economic overfishing. If the OAE condition shows that the utilization of blue swimming crab resources is inefficient and causes big losses including biological, environmental, social and economic aspects. The management that can be carried out is 1) Arrangement of regulatory efforts, namely setting the number of trips and setting patterns and seasons. 2) Policy in setting prices in fisherman's operational costs.

Abstract

Estuaries are biogeochemical hot spots; they receive large inputs of nutrients from land and oceans to support high primary productivity rates. Estuaries also as a place for waste disposal allowing the accumulation that endangers the environment and organisms. Water quality assessment can be done by analyzing physical, chemical, and biological characteristics using microalgae. This study aimed to analyze the microalgae community as aquatic environment bioindicator. Survey method was used and sampling location was in four different sites of Peniti Estuary by purposive sampling. Identification of microalgae, density, biological indexes, and water quality measurements was taken in this research. The result showed microalgae community consists of 68 genera and Euglenophyceae was a component of microalgae with the highest percentage of abundance (60.93%). The most commonly found genera were Trachelomonas, Phacus, Lepocinclis, and Sphaerellopsis. The abundance of microalga was ranging from 0.5-2141.5 ind/L. Biological indexes indicate that Peniti estuary environment was belonging to moderately polluted and water eutrophication. The abundance of microalgae was influenced by physico-chemical factors such as temperature, current, nitrate and phosphate content.

Abstract

Kemasan sebagai alat pelindung produk dari kerusakan yang banyak digunakan yaitu plastik sintetis memiliki harga relatif murah dan mudah didapat tetapi sukar terurai sehingga menimbulkan pencemaran lingkungan. Edible film merupakan alternatif bahan pengemas yang ramah lingkungan. Tujuan penelitian ini untuk mengetahui pengaruh jenis plasticizer terhadap karakteristik edible film dari karagenan K. alvarezii. Metode penelitian yang digunakan yaitu eksperimental laboratorium menggunakan Rancangan Acak Lengkap (RAL) dengan perbedaan jenis plasticizer (Gliserol, sorbitol, sukrosa dan glukosa). Analisis data menggunakan Sidik ragam dan apabila terdapat perbedaan perlakuan dilakukan uji lanjutan Uji Tukey. Hasil penelitian menunjukkan bahwa jenis plasticizer yang berbeda tidak berpengaruh terhadap karakteristik edible film dari karagenan (kuat tarik, elongasi, dan ketebalan film) namun memberikan pengaruh terhadap laju transmisi uap air. Karakteristik terbaik diperoleh pada edible film karagenan dengan plasticizer gliserol dihasilkan nilai kuat tarik 22,81 MPa, elongasi 4,01%, ketebalan 0,0178 mm, dan laju transmisi uap air 3,5413 g/m2.jam. Packaging as a protective device for products from damage widely used namely synthetic plastic has a relatively cheap price and is easy to obtain but difficult to decompose, causing environmental pollution. Edible film is an alternative packaging material that is environmentally friendly. The aim of this research was to determine the effect of the type of plasticizer on the characteristics of edible films from K. alvarezii carrageenan. The research method used was experimental laboratory using a Completely Randomized Design (CRD) with different types of plasticizers (Glycerol, sorbitol, sucrose and glucose). Data analysis using Analysis of Variance and if there were differences in treatment, the Tukey Test continued. The results showed that the different types of plasticizers did not affect the characteristics of edible film from carrageenan (tensile strength, elongation, and film thickness) but had an influence on the transmission rate of moisture. The best characteristics were obtained from carrageenan edible film with glycerol as plasticizer which resulted in tensile strength values of 22.81 MPa, elongation of 4.01%, thickness of 0.0178 mm, and water vapor transmission rate of 3.5413 g/m2.hour.

Abstract

Eutrophication is the main problem in Rawa Pening that occurs due to the high supply of organic material from various sources. The high level of nitrate in the water can be reduced through denitrification mechanism using some bacteria such as Pseudomonas group. This bacteria group was often isolated using Glutamate Starch Phenol (GSP) selective media. This study aims to identify the species from the floating net cage of Rawa Pening that was suspected as Pseudomonas group based on colony morphology in GSP through molecular approach, build the phylogenetic tree, and analyze the genetic distance. The research was conducted from January to May 2020. The molecular approach was carried out using the Polymerase Chain Reaction (PCR) method with 16S rRNA gene amplification. The results of BLAST analysis showed that isolate D1 which obtained from water samples in the Rawa Pening floating net cage area had 99.23% homology with Acinetobacter junii strain tu13. The partial sequence of DNA was already deposited to GenBank with accession number LC603787. The phylogenetic tree construction was built using Neighbor-Joining analysis on MEGA X software. The results showed that isolate D1 was related to Acinetobacter junii strain tu13 with 0.006 genetic distance while Pseudomonas fluorescens with 0.144 genetic distance. The result revealed that isolate D1 closely related to A. junii rather than Pseudomonas group. This study indicated that GSP medium has a sensitivity range at the Order level, namely Pseudomonadales.

Abstract

Nila salin (Oreochromis niloticus) adalah ikan nila yang dibudidayakan pada perairan payau dengan memanfaatkan sifat euryhaline (dapat mentoleransi perubahan salinitas dengan rentang yang lebar). Ikan ini mampu tumbuh dan berkembangbiak pada salinitas 0 – 20 ppt dan masih dapat hidup pada salinitas 35 ppt. Keunggulan ikan nila adalah pertumbuhan cepat, mudah berkembangbiak, dan mudah beradaptasi dengan lingkungan. Pembudidaya ikan di Kecamatan Tayu Kabupaten Pati mulai mencoba budidaya nila salin karena kegagalan dalam budidaya udang. Lahan yang digunakan untuk budidaya nila salin di Kecamatan Tayu pada tahun 2015 seluas 2 Ha dan meningkat menjadi 582 Ha pada tahun 2018. Penelitian ini bertujuan untuk menganalisis kesesuaian lahan budidaya nila salin di Pertambakan Kecamatan Tayu. Metode yang digunakan adalah metode survei. Analisis kesesuaian lahan dilakukan dengan metode matcing untuk mendapatkan kelas kesesuaian lahan. Hasil analisis kesesuaian lahan tambak ikan nila di lokasi penelitian digolongkan pada tingkat kesesuaian kelas S3 (sesuai marginal) dengan nilai rata-rata 72,6 %. Faktor pembatas yang perlu menjadi perhatian serius adalah fluktuasi Oksigen terlarut, potensial redoks dan TSS. Saline tilapia (Oreochromis niloticus) is a tilapia fish that is cultivated in brackish waters by utilizing its euryhaline properties (it can tolerate a wide range of changes in salinity). This fish is able to grow and reproduce at a salinity of 0 – 20 ppt and can still live at a salinity of 35 ppt.. The advantages of tilapia are fast growth, easy to breed, and easy to adapt to the environment. Fish cultivators in Tayu District, Pati Regency, started trying saline tilapia cultivation due to failures in shrimp cultivation. The land used for saline tilapia cultivation in Tayu District in 2015 was 2 hectares and increased to 582 hectares in 2018. This study aims to analyze the suitability of saline tilapia cultivation land in Tambakan, Tayu District. The method used is a case study survey method. Land suitability analysis was carried out using the matching method to obtain land suitability classes. The results of the suitability analysis of tilapia ponds in the research location were classified at the level of suitability for S3 class (marginally appropriate) with an average value of 72.6%. Limiting factors that need serious attention are fluctuations in dissolved oxygen, redox potential and TSS.

Abstract

This study investigated the relationship between sea surface temperature (SST) and chlorophyll-a (chl-a) concentration in the North Coast of Semarang, Indonesia. The data were collected using Moderate Resolution Imaging Spectroradiometer Satellite (Aqua-MODIS) chl-a level-3 standard mapped image for a period of five years (2015–2019). Due to cloud coverage, monthly averaged data were used in this study. The result shows that monthly averaged SST ranged from 28.1°C to 31.3 °C. This SST is relatively higher in the transition season (especially in the first transition season) compared to the east and west monsoons season. Chl-a concentration ranged from 0.002 mg/m3 to 1.388 mg/m3. This concentration fluctuates according to the seasonal winds. The maximum concentration of chl-a occurred in the west monsoon season, while the minimum one happened in the second transition season. Using the Pearson correlation coefficient, the correlation is -0.092, which indicates a weak negative correlation between SST and chl-a concentration. This study is expected to give an insight into the potential fishing ground since the chl-a concentration can be such an indicator for the presence of fish.

Abstract

Free radicals contribute to human health problem resulting in various human diseases, including central nervous system injury, cancer, inflammations, and the decrease of organ function related to oxidation. This condition has encouraged the effort of finding new natural antioxidant and anti-inflammatory sources. Macroalgae act as excellent natural resources due to their bioactive potential with diverse applications in various fields. Eucheuma cottonii belonging to Rhodophyceae grow abundantly along Lemukutan Island waters, however, their existence has not been exploited. This study aims to evaluate antioxidant and anti-inflammatory activities of ethanol extract of E. cottonii from Lemukutan Island waters, West Kalimantan. The observation of antioxidant activity was done using the method of DPPH (1,1-diphenyl-2-picrylhydrazyl) with UV-vis spectrophotometer, while anti-inflammatory acyivity activity was determined using the RBCs membrane stability method. The ethanolic extract of E. cottonii had potential antioxidant activity with IC50 of 127.75 ppm and was classified as moderate category. Extracts showed also anti-inflammatory acyivity activity with the concentration of 219.83 ppm. Red macroalgae E. cottonii can be used as potential natural antioxidant and anti-inflammatory agent.

Abstract

Mustard is a waste contain protein produced from the shell stripping process of blue swimming crab. It has a great potential to be processed as protein hydrolysate. Papain enzyme could be a hydrolysis agent due to its specific function and didn’t cause protein damage. The liquid product of the mustard hydrolysate protein requires a drying process to become a powder product. The drying process method is known as foam-mat drying. The research aims to determine the effect of papain enzyme addition on the characteristics of mustard protein hydrolysate from blue swimming crab and the best enzyme concentration. The research method was  used a completely randomized design (CRD) with different enzyme concentration treatments (0%, 5%, 7.5% and 10%). The data obtained were tested using  ANOVA test, in order  to determine differences  between  treatment a  Honestly Significant Difference (HSD) test were applied. The results showed that the addition of different papain enzyme concentrations had a significantly different effect (P<5%) on all test parameters (yield, hydrolysis degree, protein content, moisture content, fat content, ash content, protein digestibility, and amino acid profile). Based on the results of the study, the best mustard hydrolysate protein were the addition of 10% papain enzyme concentration with a yield value of 19.14±0.29%, hydrolysis degrees of 40.19±0.24%, protein content 49.21±0.83% (dw), the moisture content 7.20±0.20%, fat content 1.49±0.29%, ash content 7.22±0.20%, protein digestibility 88.35% and the highest amino acid level was glutamic acid (3.746%).
