Judul: Level of Traditional Knowledge and Language Vitality Gayo Lut in Central Aceh
Abstrak: Pengetahuan tradisional masyarakat Gayo Lut sangat penting dalam upaya pelestarian keanekaragaman hayati. Pengetahuan diwariskan melalui bahasa sebagai media komunikasi yang menyimpan kekayaan pengetahuan dan cara dalam mengelola keanekaragaman hayati, oleh karena itu menjadi penting untuk diukur. Penelitian ini bertujuan untuk: (1) mengukur tingkat pengetahuan tradisional dan vitalitas bahasa Gayo Lut, dan (2) mengidentifikasi faktor pembatas terhadap tingkat pengetahuan tradisional dan vitalitas bahasa Gayo Lut. Pengumpulan data dilakukan dengan wawancara secara purposive sampling menggunakan TraLavi (Traditional Knowledge and Language Vitality Index) yang berfokus pada tumbuhan pangan. Kriteria yang digunakan yaitu prioritas bahasa (A), pengambilan informasi (B), erosi pengetahuan tradisional (C), pengenalan visual (D), dan pewarisan pengetahuan tradisional (E). Hasil penelitian menunjukkan bahwa dengan skor TraLaVi sebesar 0,85 yang berarti bahasa Gayo Lut termasuk pada status aman. Faktor pembatas tingkat pengetahuan tradisional dan vitalitas bahasa Gayo Lut yaitu usia (p-value 0,001) dan status menikah (p-value 0,006) berpengaruh secara signifikan. Perbedaan usia dapat memengaruhi tingkat pengetahuan tradisional dan vitalitas bahasa Gayo Lut, sedangkan status menikah yang sesama Gayo Lut mampu memengaruhi keberlanjutan bahasa., Traditional knowledge of the Gayo Lut community is very important in efforts to conserve biodiversity. Knowledge transmission through language as a communication tool that stores a assests of knowledge and method to manage biodiversity, therefore it is important to measure. This study aims to: (1) measure the level of traditional knowledge and vitality of the language Gayo Lut, and (2) identify the limiting factors of traditional knowledge and language vitality Gayo Lut. Data were collected by interview in purposive sampling using TraLaVi (Traditional Knowledge and Language Vitality Index) which focuses on food plants. The criteria used are language priority (A), retrieval of information (B), traditional knowledge erosion (C), visual recognition (D), and traditional knowledge transmission (E). The results a TraLavi score of 0,85 meaning that the Gayo Lut language is included in the safe status. Limiting factors in level of traditional knowledge and language vitality Gayo Lut such as age (p-value 0,001) and marital status (p-value 0,006) had a significant effect. Differences in age can affect the level of traditional knowledge and language vitality Gayo Lut, while the marital status of the same Gayo Lut can affect the sustainability of the language.

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
