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: The Determinants of Waqf Water Station Usage and Their Impact on The Level of Water Consumption and Expenditures of IPB University Students
Abstrak: Wakaf memiliki peran yang penting dalam pembangunan infrastruktur, upaya pemerataan pendapatan, dan peningkatan kemandirian ekonomi di masyarakat. Oleh karena itu, badan pengelola bisnis, investasi, dan wakaf (BP Biswaf) IPB University menggunakan wakaf sebagai sumber dana untuk membangun dan mengoperasikan water station. Masalah ketersediaan air bersih yang layak diminum menjadi perhatian serius pada saat ini. Sumber daya air bersih yang seharusnya mudah diakses oleh masyarakat kini semakin langka dan mahal harganya. Setiap individu setidaknya membutuhkan konsumsi air sebanyak 2 liter per hari. Tujuan dari penelitian ini adalah menganalisis tingkat pengeluaran mahasiswa IPB University dengan membandingkan alokasi pengguna wakaf water station dengan non pengguna wakaf water station, menganalisis pengaruh wakaf water station terhadap konsumsi air minum, menganalisis faktor-faktor yang memengaruhi perilaku mahasiswa IPB University dalam menggunakan wakaf water station. Metode yang digunakan dalam penelitian ini adalah analisis deskriptif dan metode regresi logistik. Hasil penelitian ini menunjukkan bahwa pengaruh water station mempunyai dampak yang signifikan terhadap pengeluaran mahasiswa dalam membeli air minum dengan penghematan air minum sebesar Rp73.333/bulan. Determinan penggunaan wakaf water station adalah aktivitas, aksesibilitas, dan pendapatan. Wakaf water station telah memberikan pengaruh yang signifikan terhadap tingkat konsumsi air minum pengguna., Waqf plays a crucial role in infrastructure development, income redistribution efforts, and enhancing economic self-reliance in society. In this context, the business, investment, and waqf management agency (BP Biswaf) of IPB University utilizes waqf as a source of funding to build and operate water stations. The issue of access to clean and potable water has become a serious concern at present. Clean water resources that should be easily accessible to the community have become increasingly scarce and expensive. Each individual needs a minimum water consumption of 2 liters per day. The objectives of this study are to: analyze the expenditure levels of IPB University students by comparing the allocation of waqf water station users with non-users, analyze the impact of waqf water stations on drinking water consumption, and analyze the factors influencing the behavior of IPB University students in using waqf water stations. The research employs descriptive analysis and logistic regression methods. The results of this study indicate that the presence of water stations has a significant impact on students' expenditure in purchasing drinking water, resulting in cost savings of Rp73,333. Factors influencing students' usage of waqf water stations include their activities, accessibility, and income levels. The waqf water station has a significant influence on the level of drinking water consumption among its users.

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.
