Judul: Analisis Harga Pokok Produksi Domba Akikah di Jasa Layanan Akikah Wilayah Bogor Barat
Abstrak: Aqiqah is slaughtering small ruminant, like goat and sheep, as expression of gratitude of parents on the birth of their child. Price or service fee of aqiqah is different at every business unit, so the research done by considering the cost of production. The study conducted at three sites sheep aqiqah services in West Bogor for three months. Data analysis using descriptive data by calculating the cost of production, income, and revenue cost ratio (RC-1 ratio). Production cost of ram weight 13 kg to 25 kg range from Rp 1 336 619 to Rp 2 180 942, while ewes in weight 13 kg to 19 kg range from Rp 946 619 to Rp 1 250 369. The differences in production cost is influenced by the cost of sheep and operational. Aqiqah service provider will receive a profit between Rp 102 131 to Rp 449 058 for every package. Aqiqah sheep RC-1 ratio has been more than 1 and the selling price has covered the production cost so that the business unit is beneficial and viable.

Judul: Identification of Sheep Breeds Slaughtered at  Aqiqah and Slaughterhouses (Case Study in Bogor City)
Abstrak: Domba memiliki peran penting dalam berbagai macam aspek kehidupan masyarakat seperti aspek pangan maupun ekonomi. Keragaman wilayah menyebabkan begitu banyak bangsa domba yang tersebar di seluruh dunia. Karakteristik performa fisik dapat membedakan antara satu bangsa dengan bangsa lainnya. Untuk mengidentifikasi jenis domba terdapat beberapa peubah yang diamati yaitu jenis domba, jenis kelamin, umur dan bobot sebelum dipotong. Tujuan penelitian untuk mengidentifikasi jenis domba yang dipotong di tempat akikah dan tempat pemotongan hewan khusus domba. Data penelitian ini diperoleh melalui identifikasi kualitatif dan kuantitatif menggunakan metode observasi. Data yang diperoleh dianalisis secara deskriptif. Data yang diperoleh selama penelitian dimasukkan ke dalam perangkat lunak Microsoft Excel dan diproses hingga ratarata, modus, nilai maksimum dan nilai minimum ditentukan. Hasil penelitian menunjukkan jenis domba yang sering dipotong adalah Domba Ekor Tipis (DET), sebagian besar yang dipotong berjenis kelamin betina (78%) dengan umur potong terbanyak pada 1-1,5 tahun (I1) dan rata-rata bobot potong sekitar 17,83±0,1 kg., Sheep play an important role in various aspects of society such as food and economy. The diversity of regions has resulted in many breeds of sheep spread across the world. Physical performance characteristics can distinguish one breed from another. To identify sheep breeds, several variables are observed, namely sheep breed, gender, age, and weight before slaughter. The purpose of the research is to identify the types of sheep slaughtered at places for aqiqah (Islamic ritual sacrifice) and special sheep slaughterhouses. The research data was obtained through qualitative and quantitative identification using observational methods. The data obtained was analyzed descriptively. The data collected during the research was entered into Microsoft Excel software and processed to determine averages, modes, maximum, and minimum values. The results of the research show that the most frequently slaughtered breed is the Thin-Tailed Sheep (Domba Ekor Tipis, DET), with the majority being female (78%), the most common slaughter age being 1-1.5 years (I1), and an average slaughter weight of about 17.83±0.1 kg.

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.
