Judul: Fair Profit Sharing System between Fishermen and Boat Owners in Drift Gillnet at Karangantu Fishery Port
Abstrak: Kesejahteraan nelayan bergantung pada pendapatan dari hasil produksi operasi penangkapan ikan yang melewati sistem bagi hasil. Pendapatan nelayan jaring rampus rendah diduga sebagai akibat dari sistem bagi hasil yang belum berkeadilan. Tujuan penelitian ini untuk mendeskripsikan kondisi bagi hasil saat ini, menganalisis pendapatan pemilik kapal dan nelayan, serta merumuskan sistem bagi hasil alternatif dengan mensimulasikannya melalui evaluasi UMP dan mempertimbangkan beban kerja, yaitu jam bekerja, risiko kerja, psikologis, dan kenyamanan bekerja. Penelitian dilakukan 29 Januari - 7 Februari 2024 dengan sampel penelitian sebanyak 22 kapal menggunakan metode purposive sampling. Hasil penelitian menunjukkan sistem bagi hasil saat ini 50% pemilik kapal dan 50% nelayan. Namun, pendapatan ABK saat musim sedang Rp 2.424.048 tidak mencapai UMP Banten Rp 2.661.280 dan mengalami kerugian saat musim paceklik. Oleh karena itu, diperlukan sistem bagi hasil alternatif dengan pertimbangan jam bekerja, risiko kerja, psikologis, dan kenyamanan bekerja. Hasil penelitian diperoleh proporsi 37% pemilik kapal dan 63% nelayan. Proporsi jaring rampus tersebut menunjukkan pendapatan nelayan saat musim sedang Rp 3.054.300 di atas UMP dan pendapatan bersih pemilik kapal Rp 7.222.605 tetap mendapat keuntungan Rp 4.584.461 di atas BEP. Namun, musim paceklik tetap mengalami kerugian sehingga dibutuhkan strategi pekerjaan alternatif saat musim panceklik pada penelitian berikutnya.

Judul: Characteristics of Crab Gillnet and Bottom Gillnet at Karangantu Fishing port, Banten
Abstrak: Kegiatan penangkapan ikan dilakukan berdasarkan cuaca sehingga pendapatan yang diterima oleh nelayan tidak menentu sehingga terdapat hari-hari dimana nelayan tidak memiliki penghasilan. Penelitian ini dilakukan untuk mengidentifikasi sistem bagi hasil antara nelayan penggarap dengan nelayan pemilik, dengan terlebih dahulu mengidentifikasi kondisi eksisting nelayan penggarap yang termasuk nelayan kecil (≤5GT) terkait dengan dimensi kapal, biaya operasional dan pendapatan. Berdasarkan hasil penelitian diketahui desain kapal jaring rampus dan rajungan memiliki perbedaan bentuk dimana kapal jaring rajungan berbentuk double pointed, sedangkan kapal jaring rampus berbentuk transom. Sitem bagi hasil antara pemilik kapal dan nelayan untuk unit penangkapan ikan jaring rajungan dan jaring rampus di PPN karangantu adalah sama. Hasil penjualan hasil tangkapan tiap trip setengah bagian diberikan kepada pemilik kapal setengah bagian lagi dikurangi baiaya operasional yang telah dikeluarkan trip oleh pemilik kapal kemudian dibagi jumlah ABK kapal, Fishing activities are carried out based on the weather so that the income received by fishermen is uncertain, there are days when fishermen do not have income because they cant go fishing. This research was conducted to identify a profit sharing system between tenant fishermen and owner fishermen, by first identifying the existing conditions of working fishermen, including small fishermen (≤5GT) related to ship dimensions, operating costs and income. Based on the research results, it is known that the design of Bottom Gillnet and Crab Gillnet has different shapes where the crab gillnet have double pointed shaped, while the bottom gillnet are transom shaped. The profit sharing system between boat owners and fishermen for small crab gillnet and bottom gillnet fisheries at PPN Karangantu is the same. Where the proceeds from the sale of the catch for each half part trip are given to the owner of the ship for the other half minus the operational costs that have been incurred by the trip by the ship owner then divided by the number of crew.

Judul: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
