Perairan Kabupaten Cirebon merupakan salah satu wilayah yang banyak menghasilkan kekerangan, yang bernilai ekonomis tinggi dan banyak dikonsumsi oleh masyarakat. Tujuan dari penelitian ini adalah untuk menganalisis pertumbuhan dan indeks kondisi kerang batik yang ada di Perairan Cirebon. Metode penelitian ini dilakukan secara deskriptif, melalui pengumpulan data dengan menggunakan metode survei. Penelitian ini dilakukan pada bulan Februari-April 2020 di perairan Cirebon. Lokasi diperairan Cirebon dibagi menjadi tiga yang dianggap mewakili masing-masing wilayah, perairan Mundu, perairan Bondet, dan perairan Playangan. Metode analisis yang digunakan adalah analisis morfometrik dan indeks kondisi kerang. Hasil penelitian menujukkan bahwa pertumbuhan kerang batik bersifat allometrik negatif dan indeks kondisi kerang dalam keadaan kecil dan sedang.

Kabupaten Cirebon merupakan salah satu wilayah yang memanfaatkan sumber daya perikanan dan kelautan melalui usaha perikanan tangkap. Salah satu alat tangkap yang di gunakan di Kabupaten Cirebon adalah trammel net. Penelitian ini bertujuan untuk mengkaji kelayakan usaha penangkapan trammel net di Kabupaten Cirebon. Penelitian ini dilakukan pada bulan April - September 2020. Metode yang digunakan adalah survei dengan responden sebanyak 30 dengan teknik wawancara menggunakan kuisioner. Metode analisis finansial usaha yang digunakan yaitu NPV, IRR, R/C ratio dan PP. Hasil penelitian menunjukan bahwa kapal trammel net berukuran < 5 GT dan memiliki mesin penggerak berkekuatan 24 PK. Hasil analisis kelayakan usaha yang diperoleh nilai NPV rata-rata sebesar Rp150.406.777 dan bernilai positif, nilai R/C ratio sebesar 1,32 lebih dari 1, nilai IRR sebesar 47% dan PP sebesar 2,50 tahun. Hal ini menunjukan bahwa berdasarkan hasil perhitungan kelayakan usaha maka usaha trammel net layak untuk dilanjutkan dan menguntungkan, sedangkan nilai Payback Period (PP) menunjukan bahwa rata-rata nelayan trammel net dapat mengembalikan modal dalam kurun waktu 2 tahun 5 bulan. Hasil penelitian menunjukkan bahwa trammel net merupakan salah satu alat tangkap yang digunakan dan layak diusahakan oleh nelayan di Kabupaten Cirebon.Title: Feasibility Analysis of Trammel Net at the Cirebon Regency, West JavaCirebon Regency is one of the areas that utilizes fishery and marine resources in the capture fisheries business. One of the fishing gears used in Cirebon Regency is trammel net. This research aims to analyze business feasibility of trammel net at the Cirebon Regency. The survey was conducted in April to September 2020. The research method used is survey using 30 respondents with interview techniques using a questionnaire. Financial analysis method of NPV, IRR, R/C ratio, and Payback Periods analysis were used in this study. Results showed that the trammel net of <5 GT had a 24 PK propulsion engine. Results of analysis obtained an average NPV value of IDR 150,406,777 and a positive value, an R/C ratio of 1.32 more than 1, NPV 150,406,777, IRR 47% and a PP of 2,50 years. These results showed that trammel net is a feasible fishing gear being used by fishers in Cirebon regency.

Disolved oxygen plays an important role for fish living in its life environment. Information on the ammount of oxygen consumption of a fish in certain volume of water is needed in order to give balancing between the ammount of disolved oxygen and fish in it. The objective of this research is obtaining oxygen consumption level of a juvenile of brek fish (Puntius orphoides) of 5-7 cm body length. Oxygen consumption of fish was measured using a tube that equiped with DO tool (dissolved oxygent, DO), and the tube was filled by fresh water. Measurement of oxygen consumption of juvenil was done by measuring the concentration of dissolved oxygen from fresh water in the respirometer tube, began when fish had entered into the respirometer tube up to two hours observation. The result showed that oxygen consumption rate a juvenile of brek fish (Puntius orphoides) of 5-7 cm length, is ranging between 0.816 and 1.734 mg/hour.

This research was conducted with the aim to evaluate the performance of blood glucose of brek fish (Puntius orphoides) in response to stocking density stress. Fish weighing an average of 2.21 g with a weight of 27 individuals were given stocking density stress by inserting them into 9 cylindrical containers of 200.96 cm2 width and 3 L volume of peat water with stocking differently for 72 hours. These stocking density treatments are A (2 fishes/0.02 m2), B (3 fishes/0.02 m2) and C (4 fishes/0.02 m2) with three replicates. Blood glucose collected from 1 fish per container at 72 hours. The preliminary test was conducted to determine the oxygen demand of fish through the oxygen consumption level test which can then be calculated oxygen demand from the fish in accordance with the density used. The average value of blood glucose levels of brek fish that were given the stress of stocking density 2 fishes / 0.02 m2, 3 fishes / 0.02 m2 and 4 fishes / 0.02 m2 tends to be low, that is 53 mg / dL, 52.67 mg / dL and 49.33 mg / dL respectively. The response of blood glucose to stocking density stress results in stocking recommendations for culture brek fish ranging from 100-200 fish / m2.

This study aims to find out the efforts that have been made by LKS in implementing Islamic finance, the obstacles encountered and the role of LKS in implementing Islamic finance for MSME. This study was a qualitative approach in the form of a case study in Batam City.  The results showed that the oobstacles faced, limited human resources and service offices, constrained by collateral as a second way out because financing must remain secure, internal services are not optimal, understanding and awareness of the community are still happy with instant loans, do not want to be complicated so that more people make transactions with financial institutions conventional rather than LKS which assumes the process seems complicated. Micro entrepreneurs need the role of LKS, especially in terms of capital used to expand the market and develop their business so that it contributes greatly to the national economy, LKS with the institution of Bank Riau Kepri Syariah (BRKS) can provide a way out to meet the needs of a consumptive society and can cover the needs MSME investment.
