Judul: Perencanaan Penyediaan Lauk Hewani dalam Penyelenggaraan Makanan untuk Pesta Pernikahan.
Abstrak: Industri makanan khususnya katering banyak melayani kebutuhan masyarakat utamanya untuk pesta pernikahan. Penelitian ini bertujuan untuk menganalisis kesesuaian perhitungan perencanaan menu lauk hewani saat pesta dilangsungkan. Tujuan lainnya adalah membandingkan hasil perhitungan berat mentah menjadi matang dari DMM Indonesia dan USDA. Desain penelitian yang digunakan yaitu case study yang dilakukan di kantor dan dapur utama (Main Kitchen) DC Bogor. Pengumpulan data dilakukan pada bulan Desember 2017 hingga Februari 2018. Perhitungan perencanaan lauk hewani menggunakan DMM dan USDA memiliki hasil yang berbeda. USDA lebih merinci dalam perhitungan bagian daging sapi dan ayam serta proses pengolahan yang sangat mendetail. DMM Indonesia hanya menjabarkan bagian-bagian daging serta ayam yang umum digunakan seperti daging lamosir atau haas dan daging paha atau dada ayam saja. Menurut hasil perhitungan yang didapatkan, USDA memilki hasil yang lebih akurat terutama jika golongan daging yang digunakan sesuai dengan keadaan aktual di lapangan. Hasil perhitungan DMM Indonesia cenderung underestimate untuk daging ayam dan bervariasi untuk daging sapi. Perhitungan DMM Indonesia untuk ikan tidak dapat dinyatakan underestimate karena jenis ikan pada literatur dan keadaan aktual berbeda sedangkan untuk menu udang cukup akurat.

Judul: Factors Affecting the Management of Halal  Certificates by Wedding Catering Entrepreneurs in West Java
Abstrak: Kebutuhan konsumsi dalam resepsi membuat bisnis katering berpotensi menguntungkan, terkhusus jenis katering pesta. Penelitian ini bertujuan untuk menganalisis karakteristik dan faktor-faktor yang memengaruhi pengusaha katering pernikahan dalam mengurus kepemilikan sertifikat halal. Model acuan dalam penelitian ini menggunakan theory of planned behavior (TPB) yang telah dimodifikasi. Penentuan responden dalam penelitian ini menggunakan teknik incidental sampling. Responden merupakan pengusaha katering pernikahan yang ada di Jawa Barat. Pengumpulan data dari responden menggunakan kuesioner yang disebarkan secara langsung dan dianalisis menggunakan analisis deskriptif dan regresi logistik. Hasil penelitian menunjukkan bahwa variabel kontrol perilaku, demografi, dan perilaku terkait berpengaruh positif dan signifikan terhadap keputusan mengurus sertifikat halal., The need for consumption in receptions makes the catering business potentially profitable, especially the type of party catering. This study aims to analyze the characteristics and factors that affect wedding catering entrepreneurs in managing the ownership of halal certificates. The reference model in this study uses a modified theory of planned behavior (TPB). The determination of respondents in this study uses an incidental sampling technique. The respondents are wedding catering entrepreneurs in West Java. Data collection from respondents used questionnaires that were distributed directly and analyzed using descriptive analysis and logistic regression. The results of the study showed that behavioral control variables, demographics, and related behaviors had a positive and significant effect on the decision to take care of halal certificates.

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.
