Abstract

Telah dilaksanakan pelatihan penulisan karya tulis ilmiah penelitian tindakan kelas (PTK) bagi guru di SMA Negeri 1 Sukamulya. Metode pelaksanaan yang digunakan, yaitu pelatihan (in service training/IST) dan pendampingan (on service training/OST). Pada proses IST peserta mendapatkan materi yang berkaitan dengan penelitian tindakan kelas, sedangkan pada proses OST peserta didampingi dalam melakukan penulisan naskah PTK. Kegiatan pengabdian kepada masyarakat yang tujuan utamanya adalah memberikan pemahaman tentang penulisan karya ilmiah mendapat apresiasi yang baik dari pihak sekolah. Kehadiran guru dalam kegiatan mencapai 80% dari total semua guru yang direncanakan terlibat. Dalam pelaksanaan kegiatan peserta nampak bersemangat, hal ini dapat dilihat dari antusiasnya para guru dalam mengikuti seluruh kegiatan pelatihan, baik dalam pemberian materi maupun pada proses diskusi atau tanya jawab.

Abstract

[Title: The use of water hyacinth as a filler to improve the strength of lightweight brick making based on gold waste]. Research objectives is to testing the compression of lightweight brick. This research was conducted through three stages: Creating lightweight bricks (from waste mining of gold and water hyacinth) horizontally, orthogonally, and randomly. Characterization of the sample as follows: density, and compressive strength. The results show that the best compression analysis at low densities of light bricks horizontally, orthogonally and randomly in compositions: 70% GMW + 30% WH = 0.54MPa, 70% GMW + 30% WH = 1.18MPa, and 85% GMW + 15% WH = 0.73 MPa. Whereas, the density test horizontally, orthogonally, and randomly in composition variations of water hyacinth as follows: 70% GMW + 30% WH = 1.41gr/cm3, 3.40% GMW + 60% WH = 1.89gr/cm3, 85% GMW + 15 WH = 1.20 gr/cm3. It can be concluded that the filler composition is directly proportional to the compressive strength. In addition, the density is inversely proportional to the mass of the lightweight brick.

Abstract

[Title: Analysis of Copper (Cu) Mineral Content in the Mining Rock Structure using the Atomic Absorption Spectrophotometer (AAS) Method]. This research was conducted with the aim of: 1) Making chitosan based on local crab shells NTB, 2) Test the absorption of Au ions using chitosan with AAS. This research was carried out using the AAS method, namely by making chitosan from crab shells, Au stock solution which was prepared in the first stage was given chitosan powder and carried out absorption with varying times. Analysis of gold content in Au stocks that have been treated with AAS to determine the remaining Au content and Au absorbed.
