Judul: Economic, Social, and Environmental Benefit of Paperless through SIM Ormawa to Support IPB Green Campus
Abstrak: Tingginya konsumsi kertas di Kampus Institut Pertanian Bogor memerlukan strategi pengurangan yang tepat, yaitu konsep paperless. Salah satu bentuk implementasi paperless di lingkungan kampus IPB adalah penerapan paperless melalui Sistem Informasi Manajemen (SIM) Ormawa. Penelitian dilakukan guna mengetahui manfaat-manfaat kebijakan paperless melalui SIM Ormawa. Tujuan penelitian ini adalah (1) mengestimasi nilai ekonomi penghematan kertas setelah diadakannya kebijakan paperless melalui SIM Ormawa (2) mengestimasi nilai ekonomi pohon akasia sebagai penyerap karbon setelah diadakannya kebijakan paperless melalui SIM Ormawa. (3) mengidentifikasi persepsi mahasiswa terhadap manfaat sosial penerapan paperless melalui SIM Ormawa. (4) mengevaluasi penerapan paperless melalui SIM Ormawa. Metode analisis yang digunakan adalah analisis nilai efisiensi, pendekatan nilai pasar, serta skala likert. Hasil penelitian menunjukkan (1) nilai ekonomi penghematan kertas kertas setelah diadakannya kebijakan paperless melalui SIM Ormawa yaitu Rp14.299.800,00/tahun (2) nilai ekonomi pohon akasia sebagai penyerap karbon setelah diadakannya kebijakan paperless yaitu Rp707.907,00/tahun. (3) terdapat manfaat sosial dari implementasi SIM Ormawa, yaitu integrasi data base, efektivitas, transparansi, paperless, serta manfaat tanda tangan digital (otentikasi, integrasi, dan non-repudiasi). (4) mahasiswa menyatakan setuju terhadap kemudahan penerapan teknologi SIM Ormawa dan keberhasilan stakeholder dalam melakukan audit dan pengawasan, namun mahasiswa berpendapat netral terhadap keberhasilan sosialisasi SIM Ormawa., The high utilization of paper in IPB university requires the right reduction strategy, namely the paperless. IPB implement paperless application through the SIM Ormawa. The objectives of this study are; (1) to estimate the economic value of paper reduction after the implementation of the paperless policy through SIM Ormawa. (2) to estimate the economic value of acacia trees as a carbon sink after the paperless implementation (3) to identify student perceptions of social benefit from paperless implementation . (4) to evaluate the application of paperless through SIM Ormawa. The analytical method used is efficiency analysis, market value approach, and likert scale. The results showed (1) the economic value of paper reduction after the implementation of the paperless policy through SIM Ormawa was Rp14.299.800.00/year (2) the economic value of the acacia tree as a carbon sink was Rp707.907,00/year. (3) social benefit from the implementation of SIM Ormawa are data base integration, effectiveness, transparency, paperless, and the benefit of digital signatures (authentication, integration, and non-repudiation). (4) students agree on the ease of implementing SIM Ormawa technology and the success of stakeholders in conducting audits and supervision. However, students have a neutral opinion on the success of socializing SIM Ormawa.

Judul: Economic Value Analysis of Reducing Carbon Emissions Alternatives on Bogor Agricultural University Campus in Dramaga District
Abstrak: Sejalan dengan meningkatnya jumlah civitas dan aktivitas di dalam Kampus IPB, kualitas udara semakin menurun. Salah satu hal yang dapat mempengaruhi kualitas udara adalah terjadinya pencemaran udara oleh Gas Rumah Kaca (GRK). IPB kemudian mencanangkan inovasi untuk menjadi Green Campus sebagai upaya mengurangi emisi karbon. Penelitian ini bertujuan untuk: (1) mengidentifikasi jejak karbon yang terdapat di dalam Kampus IPB; (2) menganalisis skenario penurunan emisi karbon di dalam Kampus IPB, dan; (3) mengestimasi nilai ekonomi yang dihasilkan terhadap skenario penurunan emisi karbon yang akan dijalankan. Penelitian ini menggunakan metode analisis deskriptif kuantitatif, metode Weighted Sum Model (WSM), metode analisis biaya manfaat, dan metode benefit transfer untuk mengkaji tujuan-tujuan penelitian. Hasil penelitian menunjukkan 21 jenis aktivitas sumber penghasil emisi karbon di Kampus IPB selama tahun 2020 menghasilkan total emisi sebesar 69.210.132.584 kg/CO2e. Terpilih tiga alternatif upaya penurunan emisi karbon, yaitu alternatif “Zonasi parkir dan menggunakan transportasi umum yang disediakan kampus apabila ingin berkeliling” untuk aspek transportasi, alternatif “Membawa alat makan dan tas belanja sendiri” untuk aspek sampah, dan alternatif “Menggunakan energi seperlunya” untuk aspek energi. Nilai ekonomi dari alternatif aspek transportasi, aspek sampah, dan aspek energi secara berurutan adalah sebesar Rp62.509.413.531, -Rp234.548.061 (tahun pertama) dan -Rp189.735.061 (tahun berikutnya), dan Rp4.677.239.959., In line with the increasing number of civitas and activities on the IPB University, the air quality has kept decreasing. One of the things that can affect air quality is the occurrence of air pollution caused by greenhouse gasses. IPB then launched an innovation to become a Green Campus as an effort to reduce carbon emissions. This study aims to: (1) identify the carbon footprint contained in the IPB University; (2) analyze the scenarios of reducing carbon emissions in the IPB University, and; (3) estimate the economic values of the carbon emissions reduction scenarios that will be implemented. This study uses a quantitative descriptive analysis method, the Weighted Sum Model (WSM) method, the Cost Benefit Analysis (CBA) method, and benefit transfer method to examine research objectives. The results showed that 21 types of carbon emissions source activities on the IPB University during 2020 produced a total emissions of 69.210.132.584 kg/CO2e. Three alternatives for reducing carbon emissions were chosen are the alternative “Parking zonation and use public transportation provided by the campus if you want to stroll around the campus” for the transportation aspect, the alternative “Bringing your own eating utensils and shopping bags” for the waste aspect, and the alternative “Using energy as necessary” for the energy aspect. The economic values of the alternatives aspect of transportation, aspect of waste, and aspect energy respectively are Rp62.509.413.531, -Rp234.548.061 (first year) and -Rp189.735.061 (following year), and Rp4.677.239.959.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
