Judul: Value Chain Model of Anchovy (Stolephorus commersonnii) Industry with Sustainability Business in Sumenep Regency, Madura, East Java
Abstrak: Permasalahan perikanan di Kabupaten Sumenep sangat kompleks, dimulai dari penangkapan hingga pemasaran. Masalah utama meliputi penurunan produktivitas, kurangnya fokus pemerintah pada pengelolaan rantai pasok ikan teri nasi, dan keterbatasan informasi relevan. Penelitian bertujuan menciptakan model rantai pasok yang efisien, bisnis berkelanjutan, dan menguntungkan semua pelaku usaha, termasuk nelayan dan pengrajin teri nasi. Pendekatan sistem mencakup analisis kebutuhan, formulasi masalah, dan rekayasa model awal dengan diagram causal loop dan input-output. Hasil menunjukkan rantai pasok ikan teri nasi di Sumenep melibatkan tujuh pelaku utama: nelayan, pengepul, pemasok besar, industri ekspor, perusahaan induk, pengolah teri nasi krispi, dan konsumen akhir. Selanjutnya, ada tiga aliran utama: barang (hulu ke hilir), uang (hilir ke hulu dan hulu ke hilir), dan informasi (hulu ke hilir dan hilir ke hulu). Analisis nilai tambah pengolahan teri nasi di Sumenep rendah, rata-rata kurang dari 50%. Model menunjukkan target minimum produksi dan keuntungan untuk setiap pelaku usaha, termasuk nelayan pemilik kapal (1.538 kg, Rp33.846.154), pengepul (3.304 kg, Rp111.000.000), pemasok besar (314 kg, Rp35.000.000), perusahaan chirimen (1.094 kg, Rp218.776.551), dan pengolah teri nasi krispi (2 kg, Rp275.735), yang mana tiap mata rantai membutuhkan volume sekian dengan jumlah keuntungan tersebut untuk mendapatkan target minimum produksi yang ideal.

Judul: Manajemen Produksi Ikan Teri Nasi di CV. Sumber Rejeki Indramayu
Abstrak: Indramayu is the big anchovy producer in West Java. Anchovy has high selling price fish export, so it caused a lot of processing anchovy companies springing up in Indramayu, one of the company is CV. Sumber Rejeki. So the purposes of this research is to compare practical and theoretical management business of anchovy in CV. Sumber Rejeki, which includes: 1) find out the management of the anchovy raw material; 2) review management production of anchovies start from processing until marketing; and 3) assessing quality management anchovy’s dry products. The methods which used are technical and descriptive analysis, analysis of the classification of production pattern, and quality control analysis using quality control p chart. Collecting data used techniques snowball sampling by observations and an interview with samples. The result showed that the management of raw materials in CV. Sumber Rejeki has not been good for lack of control on raw material. The difference in price anchovy between fishermen and the suppliers is Rp 1.000 up to Rp 2.000. Processing anchovy in general are consisting of two processes that will be divided into the processes that more detail, meanwhile in the marketing export products, CV. Sumber Rejeki cooperate with exporting company. Chirimen product is having quality standard, based on quality analysis, quality of anchovies product by CV. Sumber Rejeki is uncontrolled. They sale 80% (222.525 kg) domestic products and 20% (55.072 kg) export products.

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.
