Judul: Penentuan Kemiripan Data Karya Ilmiah IPB Menggunakan Algoritme Levenshtein
Abstrak: IPB Scientific Data is documented periodically. This data can be used for academics and researchers to get a reference of particular research study. In this research, Levenshtein algorithm was implemented to determine the similarity between titles. The concept for calculating Levenshtein distance is minimum number of edit operations required to transform a string into another string that consists of 3 operations: 1) insertion, 2) substitution, and 3) deletion. The research shows that implementation of Levenshtein distance to determine the similirity of scientific data is difficult to be able to obtain high persentage of similarity. And the similarity rate of 34% can be used as a threshold to determine the similarity of scientific data with the title as identifier. This is able to increase AVP curve.

Judul: Aturan Asosiasi Multidimensi pada Data Nilai Mahasiswa Alih Jenis Ilmu Komputer IPB Menggunakan Algoritme Apriori dan Eclat
Abstrak: Indeks prestasi kumulatif (IPK) seorang mahasiswa merupakan hasil studi dari mahasiswa selama menempuh pendidikan. IPK akan menentukan kelulusan seorang mahasiswa dari suatu universitas. Pada Program Alih Jenis S1 Ilmu Komputer Institut Pertanian Bogor, nilai yang diperoleh setiap mahasiswa bervariasi, dari skala E (gagal), D (kurang), C (cukup), B (baik), dan A (amat baik). Nilai tersebut menarik untuk diamati mengingat mahasiswa Program Alih Jenis S1 Ilmu Komputer memiliki profil yang berbeda-beda. Penelitian ini bertujuan untuk mencari kaitan antara asal D3, IPK D3, dan nilai-nilai yang diperoleh selama perkuliahan. Untuk mengetahui pola keterkaitan antara ketiga variabel tersebut, dilakukan multidimensional association rule mining menggunakan algoritme apriori dan algoritme equivalence class transformation (Eclat). Berdasarkan aturan yang dihasilkan dari kedua algoritme tersebut, pada nilai minimum support 40% dan minimum confidence 80% dapat disimpulkan bahwa mahasiswa yang berasal dari Program Diploma IPB, pada umumnya memiliki nilai C untuk mata kuliah yang diambil dalam Program Alih Jenis S1 Ilmu Komputer, memiliki IPK D3 yang sangat memuaskan, dan berjenis kelamin laki-laki.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
