Judul: Analisis Kelayakan Usaha Pembesaran Kepiting Soka di Balai Pengembangan Budidaya Air Payau dan Laut (BPBAPL) Karawang, Kabupaten Karawang
Abstrak: Fisheries and marine sector has a very important role in contributing to the development effort in creating a better social order. One of marine culture commodity good prospects for development in the fisheries sector are soft-shelled crabs. The objectives of this research are to analyze the feasibility of soft-shelled crabs enlargement business at Karawang Aquaculture Development Center Brackish and Marine based non-financial and financial aspects. All non-financial aspects and financia aspects is feasible to do.

Judul: Analisis Kelayakan Usaha Tambak Budidaya Kepiting Soka Di Desa Pusakajaya Utara Kecamatan Cilebar Kabupaten Karawang
Abstrak: Soft Shell Crab adalah kepiting bakau yang dipanen pada saat molting untuk mendapatkan karapas baru yang dikenal sebagai kepiting soka. Tujuan penelitian ini adalah untuk menganalisis kelayakan usaha tambak budidaya kepiting soka dengan menggunakan dua skenario perhitungan. Skenario I, petani menyewa tambak dengan biaya investasi sebesar Rp 122 965 00. Sedangkan skenario II, petani membeli tambak dengan biaya investasi sebesar Rp 197 965 000. Analisis kelayakan diukur melalui analisis non finansial dan finansial. Hasil penelitian menunjukkan bahwa analisis non finansial usaha ini layak dijalankan tetapi usaha ini masih terdapat kekurangan pada aspek teknis yaitu usaha ini masih belum memenuhi peraturan pemerintah (Nomor 1/Permen-KP/2015). Hasil analisis finansial pada skenario I menunjukkan NPV sebesar Rp 125 123 297, IRR 87.72 persen, Net B/C 3.17, dan PP 2.19 tahun. Skenario II menunjukkan NPV sebesar Rp 75 530 826, IRR 32.23 persen, Net B/C 1.61 dan PP 4.12 tahun. Berdasarkan hasil analisis finansial skenario I lebih menguntungkan daripada skenario II. Analisis switching value menunjukkan bahwa usaha ini sangat sensitif terhadap perubahan penurunan jumlah produksi daripada kenaikan harga benih kepiting soka.

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.
