Judul: Penilaian Kriteria Green Building Aspek Konservasi Air dan Manajemen Lingkungan Bangunan Pada Gedung Andi Hakim Nasoetion IPB
Abstrak: Saat ini gedung-gedung di Institut Pertanian Bogor (IPB) belum memiliki sertifikat green building, khususnya dari lembaga Green Building Council Indonesia (GBCI). Oleh karena itu, gedung Andi Hakim Nasoetion Rektorat IPB dipilih sebagai objek penelitian ini, yaitu tentang penilaian green building. Perangkat penilaian yang dipakai sebagai instrumen penelitian ini adalah greenship existing building versi 1.0, khususnya kategori konservasi air dan manajemen lingkungan bangunan. Penelitian ini dilakukan dengan tujuan untuk melakukan penilaian berdasarkan kemampuan gedung Andi Hakim Nasoetion Rektorat IPB untuk memenuhi kriteria green building dalam greenship rating fools milik GBCI, khususnya kategori konservasi air dan manajemen lingkungan Bangunan. Tujuan selanjutnya adalah memberikan rekomendasi perbaikan gedung agar dapat mencapai peringkat tersertifikasi green building GBCI yang Lebih tinggi pada penilaian selanjutnya. Gedung Andi Hakim Nasoetion Rektorat IPB berdiri pada tahun 1995 dengan luas total bangunan kurang lebih 15.322 m². Gedung ini terdiri atas 6 lantai dan merupakan pusat informasi pendidikan di IPB. Hasil penelitian menunjukkan bahwa saat ini gedung Andi Hakim Nasoetion Rektorat IPB berhasil memperoleh nilai sebesar 25% (5 dari 20 poin) pada kategori konservasi air. Sedangkan pada kategori manajemen lingkungan bangunan gedung Andi Hakim Nasoetion Rektorat IPB berhasil memperoleh nilai sebesar 61.5% (8 dari 13 poin)….

Judul: Penilaian Kriteria Green Building Aspek Konservasi Air dan Manajemen Lingkungan Bangunan pada Gedung Andi Hakim Nasoetion Rektorat IPB.
Abstrak: The current buildings at Bogor Agricultural University (IPB) has not yet certified green building, especially of the Green Building Council Indonesia (GBCI). Therefore, the central administration office of IPB, Andi Hakim Nasoetion Building was chosen as the object of this research, which is about green building assessment. The device used as instrument of the assessment for this research is greenship existing building version 1.0, in particular categories of water vi conservation and building environment management. This research is aim to make an assessment based on the ability of the central administration office of IPB, Andi Hakim Nasoetion Building to implement the criteria of green building in GBCI’s greenship rating tools, in particular categories of water conservation and building environment management. Next goal is to give the building recommendations in order to achieve the higher rank of green building certified of GBCI on the upcoming assessment. Central administration office of IPB, Andi Hakim Nasoetion Building was built in 1995 with more or less 15322 m2. The building comprises 6 floors and is the central office for educational information in IPB. The Result of the research showed that at this time the central administration office of IPB, Andi Hakim Nasoetion Building has gain value by 25% (5 out of 20 points) for water conservation category. Whereas, in the category of building environment management, the building has gain value by 61.5% (8 out of 13 points).

Judul: The use of homotopy perturbation methode to solve fuzzy volterra  integral equations
Abstrak: Most phenomena in nature can be explained in mathematical models, such as fuzzy volterra integral equation. The fuzzy volterra integral equation is a nonlinear integral problem, which is usually dificult to solve by an analytical solution. In this paper, fuzzy volterra integral equation is solved using perturbaion homotopy method, which can be written as a power series in p and satisfies a certain homotopy fuction. This manuscript discuss two case studies, i.e. the case of linear and trigonometric kernel function. The result shows that greater approximation order being used, the wider convergence solution area wil be.
