Judul: Penentuan Tingkat Kemiskinan Menggunakan Logika Fuzzy pada Koperasi Baytul-Ikhtiar Bogor
Abstrak: Poverty is a problem for every country in the world, including Indonesia. Many indicators have been used to determining the level of poverty. Baytul-Ikhtiar cooperation (BAIK) is a cooperation that offers a micro-credit to the middle lower economy level. The cooperation has a problem to determine the level poverty of a person. The use of fuzzy logic system is one way to determine the level of poverty. One of model using the fuzzy logic is Mamdani model. There are some steps being taken in Mamdani model, namely fuzzification, evaluation, aggregation, and defuzzification. Inputs used in this paper are income, the number of dependent, the condition of building, and the consumption of rice. The output of this model is the level of poverty. It is compared to the output using data from the BAIK. It shows that the conformity percentage is 93,33 percent. It can be concluded that fuzzy model can be used to determine the level of poverty in BAIK cooperation.

Judul: Implementation of Artificial Neural Network Methods and Fuzzy Logic Methods for the Decision Support System for Giving Zakat.
Abstrak: Masalah kemiskinan menjadi salah satu permasalahan utama di Indonesia. Upaya yang dilakukan dalam menanggulangi kemiskinan antara lain dengan memaksimalkan potensi zakat di Indonesia. Penelitian ini mengambil kasus distribusi dana zakat di IZI (Inisitif Zakat Indonesia). IZI telah berperan dalam pengelolaan zakat serta donasi keagamaan lainnya sejak berdiri pada tahun 2015. Dalam operasional sehari-hari, dibutuhkan suatu standar dalam pembuatan keputusan pemberian zakat kepada mustahiq. Dalam hal ini, perlu standar pengklasifikasian kemiskinan seseorang yang bisa dilihat dari beberapa indikator, yaitu: pendapatan, jumlah tanggungan, nilai rumah, dan status kepala rumah tangga. Dalam penelitian ini penulis menggunakan model logika fuzzy Mamdani dan model jaringan syaraf tiruan untuk pengambilan keputusan pemberian zakat. Output kedua model ini kemudian dikonfirmasikan dengan keputusan yang sudah dijalankan selama ini di IZI. Penelitian ini menunjukan kesesuaian yang sangat tinggi (94%) antara output model logika fuzzy dan fakta keputusan di lapangan. Akurasi yang serupa juga ditunjukkan oleh model jaringan syaraf tiruan. Kedua model tersebut dapat diimplementasikan dengan baik dalam penelian ini menggunakan perangkat lunak Python. Sifat perangkat Python yang merupakan perangkat lunak open source memudahkan implementasi kedua model di IZI dan LAZNAS lainnya. Dari segi kemudahan implementasi, model jaringan syaraf tiruan relatif lebih mudah diterapkan di lapangan, karena tidak diperlukan penyusunan aturan-aturan implikasi yang relatif kompleks, seperti dalam model logika fuzzy., The problem of poverty is one of the main problems in Indonesia. Efforts made in overcoming poverty include maximizing the potential for zakat in Indonesia. This research takes the case of the distribution of zakat funds at IZI (Inisiatif Zakat Indonesia). IZI has played a role in managing zakat and other religious donations since its establishment in 2015. In daily operations, a standard is needed in making decisions on giving zakat to mustahiq. In this case, it is necessary to have a standard for classifying one's poverty which can be seen from several indicators, namely: income, number of dependents, house value, and the status of the head of the household. In this study, the authors used the Mamdani fuzzy logic model and the artificial neural network model for the decision making of giving zakat. The output of these two models is then confirmed with the decisions that have been made at IZI. This study shows very high compatibility (94%) between the output of the fuzzy logic model and the fact of the decisions in the field. Similar accuracy is also shown by the neural network model. Both models can be implemented properly in this research using Python software. The nature of Python software which is open source software facilitates the implementation of both models in IZI and other LAZNAS. In terms of ease of implementation, the neural network model is relatively easier to apply in the field, because it does not require the preparation of relatively complex implication rules, such as in fuzzy logic models.

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.
