Judul: Pengembangan sistem pemantauan sampel produksi menggunakan daerah monitor proses produksi berbasis logika fuzzy
Abstrak: Perkembangan industri yang tumbuh pesat menuntut persaingan antar industri dalam menghasilkan kualitas produk yang terbaik. Kualitas produk yang b aik diperoleh jika proses produksinya berjalan dengan baik. Oleh karena itu, perlu dilakukan suatu pemantauan untuk melihat apakah suatu proses produksi telah berjalan dengan baik atau belum. Penelitian ini bertujuan untuk mengembangkan suatu sistem pemantauan proses produksi menggunakan logika fuzzy. Logika fuzzy diterapkan ke dalam sistem menggunakan fuzzy inference system (FIS) untuk menentukan daerah monitor proses produksi. FIS membuat daerah monitor proses produksi terbagi menjadi tiga daerah yaitu daerah terkontrol, daerah atensi, dan daerah intervensi.

Judul: Sistem Pakar Prediksi Produktivitas Padi Pandan Wangi Menggunakan Logika Fuzzy
Abstrak: The increase of superior commodity production value is Indonesian government's efforts to survive in competitive trade competition. Superior commodity that has become the hallmark of Indonesia is beras pandan wangi. This commodity has a distinctive taste and fragrance, well-known in regional, national and international markets. Expert system can help the effort in order to run effectively and efficiently by predict pandan wangi paddy productivity. This system has three inference systems, the first is to determine the condition of the land with the input level of nitrogen, phosphorus, potassium and acidity level of the soil, the second is to determine the environmental conditions with rainfall input, land elevation and irrigation (water discharge). The second output of the inference will become an input for the third inference system which has pandan wangi paddy productivity as the final output. This expert system using mamdani fuzzy logic model and mean of maximum (MOM) for defuzzification. This expert system has an accuracy of 61.72%, 62.96% and 88.88% for the first, second, third inference system respectively.

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.
