Judul: Analisis Bibliometrika Berdasarkan Pendekatan Co-Words : Pemetaan Laporan Hasil Penelitian Pusat Penelitian Biologi-LIPI
Abstrak: The aim of this research is to achieve up to date information on the map of five years (2006 – 2010) researches conducted by the researchers from the Research Centre for Biology, Indonesian Institute of Sciences through technical reports published and reserved in the Library of the same institution. Method of Co-words Analysis Approach on subjects (keywords or descriptors) was implemented. Document fitting are conducted through the assessment on subject similarities and dissimilarities using Jaccard Coefficient Index. The result of this current study shows that there are three most frequently appear keywords (descriptors) for each group: Java, National Parks, and Pandanaceae. This indicates that for five years the researches carried out in the institution have been mainly focused on the exploration on Pandanaceae proceeded in the National Parks located in Java. Other subjects such as diversity, DNA, genetic diversity, habitats, Indonesia, Kalimantan, mangroves, Pandanus, reserved areas, Sulawesi, and Sumatra appear less frequent at least in the last two years, thus indicating popular research topics following the first three subjects.

Judul: Bibliometric Analysis of Mangrove Carbon Research
Distribution in Indonesia
Abstrak: Penelitian mengenai karbon mangrove yang menggunakan model alometrik sebagai penghitung biomassa sudah banyak dilakukan di Indonesia. Ketersediaan pustaka mengenai karbon mangrove yang menggunakan model alometrik semakin meningkat sehingga perlu dikaji dan dianalisis bibliometrik. Oleh karena itu, penelitian ini bertujuan menganalisis publikasi pustaka penelitian karbon mangrove di Indonesia, menganalisis distribusi penelitian mengenai karbon mangrove yang menggunakan model alometrik, serta menganalisis tema dan tren penelitian karbon mangrove Indonesia. Total pustaka diperoleh sebanyak 160 yang terdiri dari pengguna model alometrik dan pembuat model alometrik. Rhizophora apiculata, Rhizophora mucronata dan Avicennia marina merupakan spesies yang sering ditemukan pada penelitian karbon mangrove di Indonesia. Penelitian karbon mangrove sudah tersebar di 31 provinsi yang ada di Indonesia dan sebagian besar ekologinya berupa pesisir pantai. Model alometrik umum AGB dan BGB milik Komiyama et al. (2005) merupakan alometrik yang paling banyak digunakan dalam penelitian karbon mangrove di Indonesia. Kata kunci “biomass”, “mangrove”, “carbon stock” dan “carbon” merupakan kata kunci yang menggambarkan topik penelitian karbon mangrove., Research on mangrove carbon using allometric models for biomass estimation has been widely conducted in Indonesia. The availability of literature on mangrove carbon using allometric models is increasing, necessitating a thorough review and bibliometric analysis. Therefore, this study aims to analyze the publication of mangrove carbon research literature in Indonesia, analyze the distribution of research on mangrove carbon using allometric models, and analyze the themes and trends of mangrove carbon research in Indonesia. A total of 160 pieces of literature were obtained, consisting of users of allometric models and creators of allometric models. Rhizophora apiculata, Rhizophora mucronata, and Avicennia marina are species frequently found in mangrove carbon research in Indonesia. Mangrove carbon research has been conducted in 31 provinces across Indonesia, with most of the ecology being coastal areas. The general allometric models AGB and BGB by Komiyama et al. (2005) are the most widely used in mangrove carbon research in Indonesia. Keywords such as "biomass," "mangrove," "carbon stock," and "carbon" are indicative of the topics in mangrove carbon research.

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.
