Judul: Kelayakan Finansial Produk Beef Tallow dengan Pemanfaatan Lemak Trimming Sapi di Perumda Dharma Jaya
Abstrak: The business unit at Dharma Jaya, specifically the frozen meat production, generates an unused byproduct, namely trimming fat. Dharma Jaya aims to create a new product using trimming fat as the raw material to produce Beef Tallow, which is obtained by melting trimming fat and then separating the solids from the resulting liquid fat. There are two methods for making Beef Tallow: wet rendering, which involves adding water to the process, and dry rendering, which does not use water. The dry rendering method was chosen for producing Beef Tallow because it showed the best quality with a free fatty acid value of 0.205%, an iodine value of 45.684 g I2/kg, and a yield of 49%. This project aims to analyze the financial feasibility of designing a new production line for Beef Tallow. The analysis includes determining the cost of production (HPP) and cost of goods sold, Break-even Point (BEP), Revenue Cost Ratio (R/C), Payback Period (PBP), sensitivity analysis, and creating a Business Model Canvas (BMC). The analysis results indicate that the BEP per unit is 4,745.70, meaning the company needs to sell 4,745 units for the business to be considered viable. The obtained R/C is 1.20, indicating it is feasible as the value exceeds 1. The PBP is achieved in the eighth month, with a cash inflow of Rp. 475,911,779 exceeding the initial investment of Rp. 464,290,966 at the beginning month. The sensitivity analysis concludes that if the raw material prices increase by more than 20%, the business is considered no longer viable. Similarly, if the selling price decreases by more than 15%, the business is deemed no longer viable. Combining these two variables, it can be concluded that the business will become unviable if the selling price decreases by more than 5% and the raw material prices increase by more than 5%., Unit usaha pada perusahaan Dharma Jaya yakni produksi daging beku menghasilkan sisa yang tak termanfaatkan yakni lemak trimming. Dharma Jaya ingin membuat sebuah produk baru berbahan baku lemak trimming untuk dijadikan Beef Tallow yang merupakan lemak diperoleh dengan meleburkan lemak trimming yang kemudian dipisahkan antara padatan pada lemak cair yang dihasilkan. Terdapat 2 metode dalam pembuatan Beef Tallow yakni wet rendering dengan penambahan air dalam prosesnya dan dry rendering tanpa menggunakan air dalam prosesnya. Metode dry rendering dipilih sebagai proses pembuatan Beef Tallow karena menunjukkan mutu terbaik dengan nilai asam lemak bebas 0,205%, bilangan iod 45,684 g I2/kg, dan rendemen yang dihasilkan 49%. Proyek ini bertujuan untuk menganalisis kelayakan finansial pada perancangan sebuah produksi baru yakni Beef Tallow. Analisis yang dilakukan adalah penentuan harga pokok produksi (HPP) dan harga pokok penjualan, Break even point (BEP), Revenue cost ratio (R/C), Payback Period (PBP), analisis sensitivitas, dan pembuatan Business Model Canvas (BMC). Hasil analisis terhadap proyek tersebut menunjukkan BEP per unit memiliki nilai 4.745,70 yang dimana, perusahaan perlu menjual produknya sebanyak 4.745 unit supaya usaha tersebut dapat dikatakan layak untuk dijalankan. R/C yang diperoleh adalah 1,20, dimana nilai tersebut melebihi 1 dan dikatakan layak. PBP diperoleh pada bulan ke delapan, dimana pertumbuhan kas yang masuk pada bulan ke delapan yakni Rp.

Judul: Feasibility analysis of fattening beef cattle in pt prisma mahesa unggul kecamatan babakan madang kabupaten bogor
Abstrak: PT Prisma Mahesa Unggul merupakan salah satu bisnis penggemukan sapi potong. Tujuan dari penelitian ini adalah untuk menganalisis kelayakan bisnis penggemukan sapi potong dari aspek finansial dan non finansial. Metode analisis yang digunakan dalam penelitian ini adalah analisis kualitatif dan kuantitatif. Analisis kualitatif digunakan untuk melihat kelayakan bisnis dari aspek non finansial, yaitu aspek pasar, teknis, manajemen dan hukum, sosial dan ekonomi, serta lingkungan. Analisis kuantitatif digunakan untuk melihat kelayakan bisnis dari aspek finansial dengan menggunakan beberapa kriteria investasi serta analisis sensitivitas. Kriteria investasi yang digunakan adalah NPV, IRR, Net B/C, serta payback period. Nilai NPV yang diperoleh sebesar 35 879 286 506, IRR sebesar 36 persen, Net B/C sebesar 3.312, dan payback period selama lima tahun tiga bulan dua puluh delapan hari. Berdasarkan kedua aspek, bisnis penggemukan sapi potong PT Prisma Mahesa Unggul ini layak untuk dijalankan kecuali pada aspek teknis dan lingkungan karena pembersihan kandang dilakukan selama satu bulan sekali dan pengolahan limbah cair belum dilakukan secara tepat. Berdasar analisis sensitivitas, penurunan bobot sapi lebih peka dibandingkan dengan kenaikan harga sapi bakalan., PT Prisma Mahesa Unggul is one of fattening beef cattle bussiness. The purpose of this research is to analyze the feasibility of fattening beef cattle in financial and non-financial aspects. Data analysis methods used are qualitative and quantitative. Qualitative analysis used to analyze non-financial aspects such as market aspects, technical, management and legal, social and economic, and environmental. Quantitative analysis used to analyze the financial aspects using multiple investment criteria and sensitivity analysis. Investment criteria used are NPV, IRR, Net B/C, and payback period. The value of NPV is Rp 35 970 988 334, an IRR is 36 percent, Net B/C is 3.318, and the payback period is for five years and three months and twenty-six days. Based on the two aspects, fattening beef cattle in PT Prisma Mahesa Unggul is feasible to run, except the technical and environmental aspects because cleaning cages did once a month and waste water treatment has not been done properly. Based on the sensitivity analysis, weight reduction of cow more sensitive than the price increased of feeder cattle.

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.
