Judul: Pola Konsumsi dan Distribusi Bahan Bakar Kapal Ikan di Pelabuhanratu
Abstrak: Pengetahuan mengenai jumlah dan sumber pasokan BBM (Bahan Bakar Minyak). di suatu pelabuhan perikanan sangat diperlukan untuk menunjang operasi penangkapan ikan secara kontinyu. Pola konsumsi akan memberikan informasi berapa konsumsi Bahan Bakar Minyak (BBM) di suatu pelabuhan dalam waktu tertentu, sedangkan pola distribusi akan menjawab darimana seharusnya konsumsi tersebut diperoleh. Penelitian ini bertujuan untuk; 1. Menghitung konsumsi bahan bakar kapal ikan; 2. Merumuskan pola konsumsi bahan bakar kapal ikan; dan 3. Memetakan jalur distibusi bahan bakar kapal ikan.

Judul: Fuel Needs for Fishing Vessels at Palabuhanratu Nusantara Fishing Port
Abstrak: Fasilitas penyediaan Bahan Bakar Minyak (BBM) seperti Instalasi Bahan Bakar Minyak merupakan salah satu fasilitas fungsional pelabuhan perikanan. Namun nelayan masih kesulitan dalam mengakses BBM dengan harga normal dan stok yang tersedia tidak pasti. Tujuan penelitian ini yaitu mengidentifikasi jenis dan menghitung jumlah BBM yang dibutuhkan kapal perikanan di Pelabuhan Perikanan Nusantara (PPN) Palabuhanratu, mengidentifikasi jenis dan menghitung jumlah BBM yang disediakan penyalur BBM resmi, serta menentukan persediaan kebutuhan BBM dan merekomendasikan distribusi BBM yang baik bagi nelayan di PPN Palabuhanratu. Metode analisis yang digunakan yaitu analisis deskriptif dan analisis matematika sederhana. Hasil penelitian menunjukkan bahwa nelayan PPN Palabuhanratu membutuhkan BBM jenis solar dan bensin. Kebutuhan solar subsidi oleh kapal ≤ 30 GT sebesar 533.398 liter selama satu tahun. Kebutuhan solar industri sebanyak 2.556.000 liter dalam setahun. BBM jenis bensin yang dibutuhkan sebesar 233.034 liter dalam setahun. Rekomendasi untuk pendistribusian BBM yang lebih baik adalah melakukan penyederhanaan administasi perikanan agar mudah dalam mengakses BBM subsidi (satu identitas multifungsi), menggunakan perhitungan hasil penelitian untuk referensi kuota BBM dan membuka informasi akses kuota ketersediaan BBM untuk sektor perikanan pada setiap tempat pengisian BBM di sekitar PPN Palabuhanratu, dan membuat mekanisme terstruktur dan pengawasan ketat untuk pembelian BBM subsidi dan non subsidi., Facilities for providing fuel, such as installation of fuel is one of the functional facilities of fishing ports. Fishermen still have difficulty in accessing fuel at normal prices and the available stock is uncertain. The purposes of this study are to identify the type and calculate the amount of fuel needed by fishing vessels at the NFP Palabuhanratu, identify the type and calculate the amount of fuel provided by official fuel distributors, and determine the supply of fuel needs and recommend a good distribution of fuel for fishermen in NFP Palabuhanratu. The analytical method used was descriptive analysis and simple mathematical analysis. The results showed that fishermen in NFP Palabuhanratu needed diesel and gasoline. The need for subsidized diesel by ships ≤ 30 GT were 533.398 liters a year. Industrial diesel needs as much as 2.556.000 liters in a year. The type of gasoline needed were 233.034 liters in a year. Recommendations for better fuel distribution are simplifying fisheries administration so that it is easy to access subsidized fuel (one multifunctional identity), using research results calculations to reference fuel quotas and opening information on fuel availability quota access for the fisheries sector at each official fuel distributors around NFP Palabuhanratu, and create a structured mechanism and strict supervision for the purchase of subsidized and non-subsidized fuel.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
