Judul: Evaluasi Aspek Green Building Pada Gedung Andi Hakim Nasoetion Rektorat Ipb
Abstrak: Pada dasarnya green building adalah konsep untuk menghemat energi dan menggunakan proses yang bertanggung jawab terhadap lingkungan dan sumber daya yang efisien di seluruh siklus hidup bangunan. Konsep green building dapat diterapkan untuk gedung baru dan gedung terbangun. Saat awal pembangunan Gedung AHN Rektorat IPB pada tahun 1995, lembaga untuk menyelenggarakan kegiatan sertifikasi atau penilaian bangunan hijau belum ada. Green Building Council Indonesia (GBCI) atau Lembaga Konsil Bangunan Hijau Indonesia baru didirikan pada tahun 2009. Hal itu menjadi dasar penelitian ini untuk mengevaluasi gedung Rektorat IPB berdasarkan GREENSHIP yang merupakan program dari GBCI untuk kegiatan sertifikasi bangunan hijau. Tujuan dari penelitian ini adalah untuk mengevaluasi penerapan konsep green building pada gedung AHN Rektorat IPB dengan melakukan assessment atau penilaian aspek green building di gedung Rektorat IPB dengan menggunakan GREENSHIP GBCI untuk gedung terbangun versi 1.0, dan memberikan suatu rekomendasi perbaikan pada aspek green building apabila belum tercapai dan terpenuhi di Gedung AHN Rektorat IPB tanpa merubah struktural dan arsitektural gedung. Metode penelitian yang digunakan adalah metode assesment atau penilaian dengan melakukan pengukuran penilaian terhadap kriteria green building yang mengacu pada standar nasional GREENSHIP GBCI dengan sistem rating untuk gedung terbangun ver. 1.0. Hasil assessment terhadap enam aspek pada kriteria green building yang mengacu pada standar nasional GREENSHIP GBCI dengan sistem rating untuk gedung terbangun ver. 1.0, gedung AHN Rektorat IPB berhasil mendapatkan total 52 poin nilai atau 44% dari maksimal 117 poin nilai. Berdasarkan perolehan nilai tersebut maka sesuai dengan peringkat GREENSHIP GBCI, gedung AHN Rektorat IPB mendapatkan peringkat Perunggu.

Judul: Penilaian Kriteria Green Building Aspek Sumber dan Siklus Material, Kualitas serta Kenyamanan Udara pada Gedung Andi Hakim Nasoetion Rektorat IPB.
Abstrak: Green concept bulding were a current essential issue in architectural design. Bogor Agricultural University as one of Indonesian leading university whom prioritizing environmental issue should apply green concept in its own building. The fact that none of IPB buildings were equipped with greeen building certificate namely from GBCI. The aims of this study was to assess and analyze the suitability of AHN Building of IPB Rectorate to be categorized as green building. Green building criteria assessment and analyze were performed on material source and cycle aspect, air quality and comfort all of it were based on GBCI and giving recomendation on what can be done for improvement. Assessment were performed using Greenship Rating Tools versi 1.0 created by GBCI. There are two types of data in this study which is primary and secondary data. There were eight points of assessment on material source and cycle aspect which is three points of requirements and five value points. There were nine points of assessment on air quality and comfort which is one points of requirements and eight value points. The results of the assessment showed that green building implementation on AHN building of IPB Rectorate includings air quality and comfort (IHC) was reaching 35% (7 of 20 points). The results of the assessment on material source and cycle (MRC) was reaching 25% (3 of 12 points). The total accomplishment of AHN building of IPB Rectorate was reaching 36,75% (43 of 117 points), makes it granted bronze category. Rectorate building need to evaluate and fulfil its requirement to become a green building. Some of the requirement were to complete the SOP and letter of commitment of the top management about the green building initiative.

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.
