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: Cost Saving Estimation for Paperless Implementation Done by Students of IPB University in Finishing Their Thesis
Abstrak: Kertas sangat dibutuhkan sebagai media pembelajaran dalam pendidikan di Indonesia. Meningkatnya jumlah mahasiswa menyebabkan naiknya konsumsi kertas. Peningkatan permintaan ketas menyebabkan berkurangnya penyerapan karbon dalam pohon. Dengan demikian perlu penghematan penggunaan kertas di dalam kampus agar cadangan karbon tetap utuh. Tujuan penelitian ini adalah (1) Mengestimasi nilai kertas dan jumlah pohon yang digunakan sebagai bahan baku kertas untuk menyelesaikan tugas akhir mahasiswa. (2) Mengestimasi nilai efisiensi kertas dan nilai penyerapan karbon setelah diadakannya kebijakan paperless. (3) Mengidentifikasi persepsi mahasiswa mengenai penerapan paperless dalam menyelesaikan tugas akhir. Metode analisis yang digunakan dalam penelitian ini adalah perhitungan nilai kertas, analisis efisiensi serta skala Likert. Hasil penelitian menunjukan bahwa (1) Nilai kertas yang dihasilkan yaitu RP. 2.698.000 sedangkan pohon yang digunakan sebagai bahan baku kertas yaitu 71 pohon. (2) Nilai efisiensi kertas menunjukkan bahwa kebijakan paperless efisien dilakukan di dalam kampus. (3) Total skor menunjukkan bahwa mahasiswa sangat setuju dengan diberlakukannya kebijakan paperless. Saran penelitian ini diharapkan menjadi masukan kebijakan green campus di IPB University khususnya kebijakan terkait paperless., Paper is much required as learning media for education in Indonesia. The increasing amounts of students give impact on the increasing of paper waste. The demands of papers could cause the reduction of carbon absorption by trees. Therefore, reducing paper consumption is required to be implemented on campus in order to maintain the intactness of carbon stock. The objectives of this study are; (1) To estimate the cost of paper and the amount of the tree which is being a raw material to produce a paper to be used in finishing students’ thesis. (2) To estimate the efficiency cost of papers and the value of carbon absorption after implementing a paperless policy. (3) To identify students’ perceptions related to paperless policy in finishing their thesis. This study used some analysis methods such as the calculation of paper cost, efficiency analysis, and Likert scale. This study, found that; (1) The result of Paper cost is RP. 2.698.000 meanwhile the amount of the trees that used as raw materials to produce those papers are 71 trees. (2) The efficiency value of papers showed paperless policy is efficient to be implemented on campus. (3) The total score showed mostly students are strongly agree with the implementation of paperless policy. This study is expected to be a positive input to support the green campus movement at IPB University, particularly a policy in terms of paperless.

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.
