Judul: Determinan Keputusan Berwakaf Uang di Kalangan Mahasiswa IPB University
Abstrak: Wakaf uang merupakan bentuk instrumen dalam ekonomi Islam yang berpotensi dalam meningkatkan kesejahteraan masyarakat. Namun di Indonesia terdapat kesenjangan yang sangat besar antara potensi wakaf uang dengan realisasi penghimpunan wakaf uang. Tujuan penelitian ini yaitu menganalisis karakteristik mahasiswa IPB University berdasarkan demografi dan sosial-ekonomi dan tingkat literasi wakaf uang mahasiswa IPB University, serta menganalisis determinan keputusan berwakaf uang di kalangan mahasiswa IPB University. Metode yang digunakan adalah metode analisis deskriptif, analisis regresi logistik dan untuk penghitungan indeks literasi wakaf mengadopsi metode penghitungan yang dikontruksi oleh Puskas BAZNAS. Berdasarkan demografi, responden dominan berjenis kelamin perempuan dan berusia pada rentang 20 hingga 21 tahun. Sementara berdasarkan sosial-ekonomi, responden dominan tidak pernah mengenyam pendidikan Islam dan berpendapatan pada rentang Rp750.000,00 sampai Rp1.000.000,00. Berdasarkan hasil analisis data diketahui bahwa tingkat literasi wakaf mahasiswa IPB University secara keseluruhan masih masuk dalam kategori rendah. Sedangkan keputusan berwakaf uang mahasiswa IPB dipengaruhi oleh variabel literasi wakaf, religiusitas, norma subjektif, pendidikan Islam, dan pendapatan., Cash waqf is an instrument in Islamic economics that can improve people's welfare. Cash waqf is a form of instrument in Islamic economics that has the potential to improve people's welfare. However, in Indonesia, there is a very large gap between the potential of cash waqf and the realization of the collection of cash waqf. The purpose of this study was to analyze the characteristics of IPB University students based on demographics and socio-economics and the literacy level of cash waqf students of IPB University, as well as to analyze the determinants of cash waqf decisions among IPB University students. The method used is descriptive analysis method, logistic regression analysis and for calculating the literacy index of waqf adopts the calculation method constructed by Puskas BAZNAS. Based on demography, the dominant respondent is female and the age ranges from 20 to 21 years. Meanwhile, based on socio-economics, the dominant respondents have never received an Islamic education and have incomes in the range of Rp. 750,000.00 to Rp. 1,000,000.00. Based on the results of data analysis, it is known that the literacy level of waqf students of IPB University as a whole is still in the low category. Meanwhile, the decision to endow cash waqf of IPB students is influenced by the variables of waqf literacy, religiosity, subjective norms, Islamic education, and income

Judul: Factors Influencing the Decision of the  Bandar Lampung Muslim Community in Endowment of Money
Abstrak: Wakaf uang merupakan salah satu instrumen keuangan Islam yang mempunyai peran penting dalam pengembangan sosial-ekonomi dan pengentasan kemiskinan. Kota Bandar Lampung memiliki potensi wakaf uang yang sangat besar bila dilihat dari Realisasi Pendapatan Asli Daerah (RPAD) Kota Bandar Lampung yang mencapai ratusan miliar rupiah. Namun, penghimpunan wakaf uang masih belum optimal karena berbagai kendala yang menimbulkan gap antara potensi dan realisasi dimana penghimpunan wakaf uang di Kota Bandar Lampung hanya mencapai puluhan juta rupiah. Penelitian ini bertujuan untuk menganalisis faktor faktor yang memengaruhi keputusan masyarakat muslim Kota Bandar Lampung dalam berwakaf uang. Responden dalam penelitian ini berjumlah 100 orang. Metode analisis yang digunakan adalah analisis kuantitatif regresi logistik dan analisis deskriptif (skala Likert). Hasil penelitian menunjukkan bahwa variabel religiusitas, pengetahuan, dan pendapatan berpengaruh signifikan terhadap keputusan berwakaf uang masyarakat muslim Kota Bandar Lampung., Cash waqf is one of the Islamic financial instruments that has an important role in socio-economic development and poverty alleviation. The city of Bandar Lampung has a very large potential for cash waqf when seen from Regional Income Realization. However, the collection of cash waqf is still not optimal due to various obstacles that create a gap between potential and realization. This study aims to analyze the factors that influence the decision of the Muslim community in Bandar Lampung City to endow money. Respondents in this study amounted to 100 people. The method used is descriptive analysis (Likert scale) and logistic regression. The results showed that the variables of religiosity, knowledge, and income have a significant influence on the decisions of the Muslim community in Bandar Lampung City in endowment of money.

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.
