Abstract

Penelitian ini bertujuan untuk meningkatkan efisiensi penggunaan bahan kimia dan mengurangi potensi timbulnya polutan (depolutansi) yang dihasilkan dari aktivitas di Laboratorium Kimia Dasar FMIPA Undiksha menuju laboratorium yang efektif, efisien, serta berwawasan green chemistry. Metode penelitian yang dipakai adalah metode penelitian tindakan (Action Research) yaitu suatu proses yang dilalui oleh peneliti untuk menangani permasalahan (di Laboratorium Kimia Dasar). Metode yang akan dilakukan adalah implementasi 3RH (Reduce, Reuse, Recycle, dan Handle) dalam manajeman bahan dan penanganan limbah Laboratorium Kimia Dasar FMIPA Undiksha. Data yang dikumpulkan adalah berkaitan dengan inventori bahan kimia, identifikasi jumlah pengunaan bahan kimia pada prosedur yang sudah ada, serta jumlah kuantitas timbulan limbah laboratorium selama kurun waktu 1 (satu) semester, dan data hasil penerapan metode 3RH. Dengan memakai data skunder dan data primer yang diperoleh dilakukan analisis deskriptif komparatif implementasi 3RH dalam manajemen bahan kimia dan manajemen limbah laboratorium. Hasil penelitian ini adalah penerapan metode 3RH ((Reduce, Reuse, Recycle, dan Handle) dapat menekan penggunaan bahan-bahan kimia untuk keperluan praktikum di laboratorium Kimia Dasar hingga 60-95% dan mengurangi timbulan polutan dari hasil aktivitas laboratorium kimia. Kata-kata Kunci: depolutansi, efisiensi, manajemen bahan, 3RH AbstractThis study aims to improve the efficiency of the use of chemicals and reduce the potential pollutants (depollutants) resulting from activities in the Chemistry Laboratory of Undiksha towards effective, efficient, and insightful green chemistry. The research method is a method of action research (Action Research) is a process through which the investigator to handle the problem (at the Laboratory of Chemistry). The method that will be done is the implementation 3RH (Reduce, Reuse, Recycle, and Handle) in materials management and waste handling FMIPA Undiksha Basic Chemistry Laboratory. The data collected is related to the inventory of chemicals, the identification number of the use of chemicals in existing procedures, as well as the quantity of laboratory waste generation during the period of 1 (one) semester, and data is the result of applying the method 3RH. By using secondary data and primary data do comparative descriptive analysis 3RH implementation in the management of chemicals and waste management laboratory. The result of this research is the application of methods 3RH ((Reduce, Reuse, Recycle, and Handle) can reduce the use of chemicals for purposes of laboratory experiments Chemistry up to 60-95% and reducing the generation of pollutants from the chemical laboratory activity. Keywords: depolutansi, efficiency, materials management, 3RH

Abstract

Telah dilaksanakan kegiatan Pengabdian kepada Masyarakat (P2M) dalam bentuk Pelatihan Keterampilan 4M (Menata, Menyimpan, Mempersiapkan, dan Memodifikasi) Alat/Bahan Praktikum Bagi Guru-Guru IPA dan Laboran SMP di Kecamatan Sukasada, Kabupaten Buleleng. Kegiatan ini bertujuan untuk meningkatkan kompetensi pengetahuan dan keterampilan Guru IPA (Pengelola Laboratorium) dan Laboran IPA SMP untuk menata, menyimpan, mempersiapkan, dan memodifikasi alat/bahan praktikum dalam rangka mendukung pembelajaran IPA. Evaluasi kegiatan ini dilakukan terhadap proses dan produk kegiatan. Evaluasi proses berkaitan dengan kehadiran peserta, semangat mengikuti kegiatan, dan kerja sama. Evaluasi proses dilakukan terhadap aktivitas peserta selama kegiatan berlangsung. Evaluasi produk dilakukan terhadap hasil karya praktek (berupa modifikasi alat praktikum) IPA dengan memanfaatkan bahan dari lingkungan sekitar dan uji kelayakan produk. Penskoran dilakukan dengan skala Likert (dengan bantuan rubrik penilaian) dan dianalisis secara deskriptif.

Abstract

Community service activities (P2M) have been implemented in the form of training in strengthening chemical literacy for laboratory assistants and managers of junior high science laboratories in Buleleng Regency. This activity aims to provide strengthening and enhancement of the ability of chemical literacy of Labors and Managers of Science Laboratory. The method used is the education-training and mentoring method. Implementation form is in service and on service in the form of lectures, workshops practices. Realization of activities includes the identification of potentially hazardous materials, substance of science practicum, characterizing the risk of hazardous chemicals, identifying ways to handle and mitigating chemical hazards, maintaining safety and health work in the laboratory and how to handle accidents due to chemicals. The outputs of this activity are posters/work instructions for hazardous chemicals in the science laboratory, chemistry literacy modules, increased competence in chemical literacy, and the scientific article in a national journal.

Abstract

Problems often occur in sample testing using the FTIR instrument, one of which is that the spectrum quality of the measurement results is not optimal. This has implications for the accuracy of the test results. This condition indicates that the performance of the tool is not optimal. The non-optimal quality of this spectrum is thought to be influenced by the composition factor and the thickness of the sample-KBr which is measured not in accordance with the legibility limits of the instrument. To overcome this problem, it is important to conduct a study to find out the optimum composition and thickness of the KBr-sample which can be measured properly by the instrument. The purpose of this study was to optimize the performance of the FTIR device through a study of the optimum composition and thickness of the KBr-sample so that a good spectrum was produced in the sample measurement using FT-IR type IRAffinity-1 Shimadzu. This research is an experimental research with infrared spectrophotometry method, using the One Shot Case Study design. The treatment is a measurement of the variation in the composition of the sample-KBr and the thickness of the sample. The spectrum resulting from the reading of the FT-IR spectrophotometer is interpreted to include wave number and transmittance percent. The results of the readings of each variation are compared with the standard spectrum to see the optimization of the measurement results so that the best spectrum is obtained. The results showed that the optimum ratio of the sample-KBr composition was 4% and the optimum thickness was 1/2 pan.
