Judul: Structural Design and Financial Feasibility in Cold Chain Mobility Services
Abstrak: Di era globalisasi, teknologi informasi dan komunikasi memainkan peran kunci dalam berbagai aspek kehidupan, termasuk transportasi. Salah satu inovasi penting adalah layanan Cold Chain Mobility Service, yang menjaga kualitas produk rentan suhu selama distribusi. Industri rantai dingin Indonesia tumbuh pesat, namun kapasitasnya masih kurang. PT Toyota Motor Manufacturing Indonesia (TMMIN) merespon dengan TOMONESIA dan TOMOLOGI, solusi penyimpanan dan distribusi dengan suhu terkontrol. Proyek ini bertujuan untuk merancang struktur dan kelayakan finansial untuk Cold Chain Mobility Service. Proyek ini juga menggabungkan aspek risiko, finansial, dan pasar dalam merancang layanan ini, menggunakan metode Analisis situasional Van der Vorst, analisis biaya historis, dan Cost Benefit Analysis. Kelayakan finansial dianalisis melalui Cash Flow, NPV, IRR, Benefit/Cost Ratio (B/C), Payback Period (PP), Profitability Index (PI), dan Return on Investment (ROI), serta analisis sensitivitas. Hasilnya menunjukkan investasi ini layak dengan NPV Rp6.663.703.918, IRR 87,10%, dan Payback Period 2 tahun 1 bulan. Proyek tetap layak meskipun terjadi perubahan ekstrim pada variabel utama. Hal ini menekankan pentingnya strategi mitigasi risiko dan pengelolaan operasional yang efektif untuk keberlanjutan layanan di tengah dinamika bisnis yang berubah., In the era of globalization, information technology and communication play a pivotal role in various aspects of life, including transportation. A significant innovation is the Cold Chain Mobility Service, which preserves the quality of temperature-sensitive products during distribution. Indonesia's cold chain industry is growing rapidly, yet its capacity remains insufficient. PT Toyota Motor Manufacturing Indonesia (TMMIN) has responded with TOMONESIA and TOMOLOGI, solutions for controlled temperature storage and distribution. This project aims to design the structure and assess the financial feasibility of the Cold Chain Mobility Service. It integrates risk, financial, and market aspects using methods such as Van der Vorst's situational analysis, historical cost analysis, and Cost Benefit Analysis. Financial feasibility is evaluated through key metrics like Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PP), along with other financial considerations. One-way sensitivity analysis is also employed. The results indicate the investment's viability with an NPV of Rp6.663.703.918, IRR of 87.10%, and a Payback Period of 2 years and 1 month. The project remains viable even under extreme changes in key variables, underscoring the importance of effective risk mitigation strategies and operational management for sustaining the service amidst evolving business dynamics.

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.
