Judul: Risk Analysis on the Hairtail Supply Chain Landed at Palabuhanratu Archipelago Fishery Port, Sukabumi
Abstrak: Aktivitas rantai pasok ikan layur di Pelabuhan Perikanan Nusantara Palabuhanratu tidak terlepas dari risiko. Analisis risiko pada rantai pasok ikan layur diharapkan dapat meminimumkan risiko yang mungkin terjadi. Tujuan penelitian ini adalah mengidentifikasi struktur rantai pasok ikan layur, menganalisis risiko pada rantai pasok ikan layur, dan merumuskan strategi dalam upaya meminimumkan risiko rantai pasok ikan layur. Penelitian ini menggunakan metode accidental sampling. Hasil penelitian menunjukkan bahwa terdapat dua pola aliran distribusi ikan layur di Palabuhanratu, Akar penyebab masalah yang dominan adalah masalah penanganan, yang menimbulkan empat jenis risiko yaitu risiko di atas kapal, risiko di dermaga, risiko di perusahaan ekspor (CV. Duta), dan risiko di pasar lokal, dengan tingkat risiko yang berbeda-beda. Strategi dalam upaya meminimumkan risiko rantai pasok ikan layur di Palabuhanratu ialah mengembangkan perikanan layur berkelanjutan, mengembangkan teknologi penanganan ikan layur yang baik dan efisien, menerapkan standar dan pelatihan kualitas nelayan menyediakan fasilitas gudang penyimpanan dingin (cold storage), membuat forum kerjasama nelayan layur, meningkatkan manajemen usaha dan kerjasama antar kelompok nelayan., Activities associated with the hairtail supply chain at the Palabuhanratu Archipelago Fishery Port are not risk-free. Analyzing the hairtail supply chain's risk is intended to help reduce potential dangers. This study's objectives were to define the hairtail supply chain's organizational structure, assess its risks, and develop solutions to reduce that chain's risk. Accidental sampling is the method used in this study. The findings indicated two distinct distribution patterns for hairtail at Palabuhanratu. The main source of the issue was handling issues, which led to different forms of risk with varying degrees: risk on board, risk at the dock, risk in export enterprises (CV. Duta), and risk in the local market. A sustainable hairtail fishery is being developed at Palabuhanratu to reduce risk in the hairtail supply chain, as are effective hairtail handling techniques, putting in place quality requirements and training for fishermen who provide cold storage facilities for warehouses (cold storage), offering a venue for hairtail fishermen to collaborate and enhance business management and intergroup cooperation.

Judul: The Fishing Season and Catch Feasibility of Hairtail fish (Trichiurus spp) in Palabuhanratu Fishing Port.
Abstrak: Ikan layur (Trichiurus spp) merupakan ikan demersal ekonomis penting dan salah satu komoditas ekspor yang potensial di PPN Palabuhanratu, Sukabumi. Ikan layur di Teluk Palabuhanatu dominan ditangkap menggunakan alat tangkap pancing layur. Informasi mengenai musim penangkapan dianggap sebagai faktor penting agar kegiatan penangkapan ikan efektif dan efisien. Penelitian ini betujuan untuk mengetahui pola musim penangkapan ikan layur, Catch Per Unit Effort, kelayakan hasil tangkapan, dan korelasi antara panjang total dengan panjang mulut dan lebar bukaan mulut ikan layur. Penelitian ini menggunakan metode penelitian deskriptif dengan jenis penelitian studi kasus. Metode analisis data yang digunakan yaitu metode rata-rata bergerak, analisis CPUE, metode hubungan panjang berat, dan analisis regresi linear. Hasil penelitian menunjukkan pola musim ikan layur terdapat pada bulan April, Juni, Agustus, September, Oktober, dan November berdasarkan nilai indeks musim penangkapan. Catch Per Unit Effort (CPUE) tertinggi dari pancing layur tahun 2015-2019 terjadi pada tahun 2019 dan nilai CPUE bulanan tertinggi pada bulan Oktober. Ukuran rata-rata ikan layur lebih besar dari kali pertama matang gonad dan masuk kedalam kategori layak tangkap. Korelasi antara panjang total dan panjang mulut serta lebar bukaan mulut dapat dijadikan acuan dalam menentukan panjang dan lebar mata pancing yang digunakan dalam alat tangkap pancing layur., Hairtail fish (Trichiurus spp) is an economically important demersal fish and one of the potential export commodities in PPN Palabuhanratu, Sukabumi. Mostly, hairtails in Palabuhanratu Bay are caught by hand line. The information of hairtails season is considered as an important factor to make fish activities are more effective and efficient. Objectives of this research are to understanding about the hairtail fishing season, catch per unit effort (CPUE), the feasibility of catches and correlation between total length with mouth length and mouth opening width of hairtail fish. This research was applied descriptive methods with case study. Data analysis was used moving average, CPUE, fish lenght and weight relations methods, and linear regression analysis. The results of this research showed the fishing season occured in April, June, August, September, October, and November. The highest Catch Per Unit Effort (CPUE) value of hand line from 2015-2019 was in 2019 and the highest monthly CPUE values was in October. The average size of haitail fish is larger than length of maturity and into the category of worth catching. correlation between total length with mouth length and mouth opening width of hairtail fish can be use as a reference in determining the length and width of the hook which is used in fishing gear.

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.
