Abstract

Copper is one of the toxic metals for health and the environment. In humans, high doses of copper metal can cause vomiting, dizziness, weakness, kidney and liver symptoms, anemia, to coma, and in severe cases, the patient can die. Judging from the dangers, proper waste management is needed to reduce the side effects of these pollutants. A practical and inexpensive technology is an adsorption adsorption technique using an efficient and easily available natural adsorbent, namely tofu dregs. The protein contained in tofu is one of the reasons for using tofu waste as an adsorbent. The absorption of amino acids that form two-charged ions (zwitter ions) is owned by proteins. Toxic metal can be bound to protein as metallotionein. The study consisted of four stages, namely (1) Analysis of initial copper content in silver craft waste; (2) Preparation of tofu waste adsorbent; (3) Characterization of tofu dregs adsorbent; and (4) variation of adsorption contact time. The study used a laboratory-scale experimental method. The adsorbent was contacted with the sample using a magnetic stirrer at various times. Instrument Atomic Absorption Spectrometer was used for the analysis of copper metal content and identification of its functional groups using an infrared spectrometer with the result that tofu waste has functional groups -OH, NH (stretching), CH (aliphatic), C=O, -OH (bending vibrations). , and CO. Copper metal content obtained is 19.5979 ppm. The optimum adsorption time was reached at 120 minutes with an optimum adsorption efficiency of 54.88%.

Abstract

Melakukan pengelolaan nilai, analisis butir soal dan hasil belajar siswa merupakan kewajiban setiap guru. Dengan begitu, guru akan dapat melakukan diagnosa masalah dalam pembelajaran, menyimpulkan tingkat ketercapaian tujuan pembelajaran, dan memutuskan program tindak lanjut. Permasalahan yang ada di SMP Islam Al-Azhar NW Kayangan adalah, hanya sebagian kecil guru yang melakukan analisis butir soal dan hasil belajar siswa yang dibuktikan dengan dokumen analisis hasil belajar yang ada. Hal tersebut disebabkan oleh sebagian besar guru menganggap anlisis butir soal dan hasil belajar sebagai kegiatan yang rumit dan memeerlukan waktu yang sangat banyak. Hampir semua guru tidak menguasai program yang dapat digunakan untuk mengolah data angka. Masalah ini dapat diatasi jika guru memiliki kemampuan mengoperasikan program Ms. Office Excel sehingga proses pengolahan nilai, anlaisis butir soal dan hasil belajar dapat dilakukan dengan lebih efisien. Kegiatan telah terselenggara dengan baik. Respon peserta kegiatan sangat baik dengan skor rata-rata penilaian total yakni 82.5

Abstract

Lombok Island has a distinctive culture and produces handicraft products with cultural motifs such as traditional woven fabrics of the Sasak tribe. Dyeing of woven fabrics using natural and artificial dyes. For artificial dyes, one of which is methylene blue dye. Residual water or former dyeing in coloring is usually immediately discharged into the environment which causes pollution or hazardous waste for living things. The presence of dyes greatly affects the environment because of their high toxic effects, can cause allergies and skin irritation, and can cause gene changes and are carcinogenic. Based on these problems, processing is needed to reduce the pollutant substances that are generated. One of the technologies used is adsorption using a natural adsorbent that is efficient and easy to obtain, namely activated carbon baggase (bagasse). Bagasse carbon made through the pyrolysis stage (carbonation process) at a certain temperature can be used as an alternative adsorbent for the adsorption of pollutant dyes. This study aims to determine the characteristics and adsorption efficiency of methylene blue by activated carbon baggase. This study used experimental methods with gravimetric techniques, batch techniques, and samples were analyzed using Uv-Vis Spectrophotometry. A 10 mL sample of 10 ppm methylene blue was contacted with one gram of activated carbon baggase. The research was conducted in six stages. The first stage is to prepare activated carbon baggase adsorbents. The second, third, and fourth stages are optimization of the methylene blue solution. The fifth to the sixth stage is the measurement of methylene blue adsorption on activated carbon baggase adsorbents with variations in pH and contact time. Characteristics of activated carbon baggase in this study obtained a moisture content of 4.64% and an ash content of 5.37%. The optimum pH was obtained at pH 5 with an adsorption efficiency of 86.4%, while the optimum contact time was obtained at 80 minutes with an adsorption efficiency of 86.9%. From these results it can be concluded that the activated carbon baggase adsorbent is effective in adsorbing methylene blue so that it can be used to overcome pollution problems caused by dye waste.
