Judul: Analisis dan desain sistem informasi untuk penerapan dokumentasi program traceability pada rantai distribusi produk tuna loin beku
Abstrak: Dinamika perubahan gaya hidup manusia dalam mengkonsumsi pangan saat ini, memungkinkan dilakukannya transportasi bahan pangan dalam jumlah yang sangat besar ke bagian dunia manapun dan memungkinkan penyebaran penyakit karena mengkonsumsi bahan pangan (foodborne disease). Penolakan negara-negara importir terkait tingginya kadar histamin pada tuna, merupakan contoh kasus besar dalam perdagangan perikanan dunia saat ini. Konsep traceability telah disarankan sebagai salah satu sistem manajemen risiko dalam menjamin mutu dan keamanan pangan global dengan fokus utama dalam memudahkan pelacakan produk. Akan tetapi, dalam implementasinya belum terdapat metodologi spesifik yang dapat diacu oleh seluruh organisasi pangan, sehingga kajian mengenai sistem informasi untuk mendukung penerapan dokumentasi dalam program traceability pada industri perikanan menjadi sangat penting untuk dilakukan. Tujuan dari penelitian ini adalah membuat kerangka sistem informasi berbasis data elektronik untuk mendukung penerapan dokumentasi program traceability pada suatu industri pengolahan selama tahapan pendistribusian ikan tuna loin beku.

Judul: Assesmen Implementasi Traceability pada Rantai Distribusi Produk Tuna Loin Beku Berbasis ISO 28000
Abstrak: Nowadays, world trade of fisheries give the positive trend, but there are many problems in food safety and quality. Traceability is important to be implemented. There are many method in traceability such as quality tracing and tracking, biotracing, etc. ISO 28000 can be a solution to ensure the safety of tuna supply chain from vessel, transit, plant, and export. The aim of this study is doing the assesment of traceability implementation in supply chain of frozen loin tuna with ISO 28000. The method was analyzed the security management in supply chain of frozen loin tuna, studied about critical risk in frozen loin tuna, determinated of network eficiency in supply chain of frozen loin tuna, and assesmented with ISO 28000. The result showed a poor food safety system in vessel and transit, but a good system in plant and export. The study in critical risk showed four critical risk which related with temperature, total microbe, and histamine. Network eficiency showed good result in process capability that means company can produced to be six sigma industry. The result of ISO 28000 assesment showed good result, but company needs continual improvement especially in management system and administration.

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.
