Masyarakat Pagutan Barat sebagian besar warganya mengalami trauma terhadap gempa Lombok 2018. Selain trauma, air PDAM yang mengalir mengalami kekeruhan selama beberapa bulan sehingga tidak dapat digunakan untuk kebersihan sehari-hari. Diperlukan suatu teknologi sederhana berupa penjernihan air agar warga dapat memanfaatkan air PDAM. Salah satu metode penjernihan air yang sederhana dan efektif adalah dengan menggunakan komposit karbon aktif (KOMAK). Karbon aktif merupakan absorben yang baik untuk menyerap polutan organik dan anorganik, senyawa-senyawa berbahaya dan bau dari air. Disamping itu, masyarakat Pagutan Barat perlu diberi edukasi pemanfaatan air yang tercemar menjadi air layak pakai sebelum air tersebut dijernihkan menggunakan alat penjernih air KOMAK. Oleh karena itu setelah dilakukan pembuatan komposit karbon aktif, diberikan juga pendampingan pembuatan prototipe alat perjernih air KOMAK sehingga prototipe ini dapat dikembangkan sendiri oleh masyarakat untuk memperoleh air layak pakai.

The overall development of Covid-19 has raised concerns in various sectors, including the agriculture, aquaculture, and livestock sectors. Based on the observations in Pagesangan Timur, Karang Anyar Village, especially around the Ittihadil Ummah Islamic boarding school, public awareness is still lacking in re-processing household waste by separating types of waste. Alternative Sustainable Food Homes with a program of fabrication of organic fertilizer from household waste allows the community to recycle household waste separated according to its type. The use of fertilizers produced is exemplified by planting 1000 trees. Fabrication of organic fertilizer and planting 1000 trees were carried out through direct outreach and practical methods. This organic fertilizer is obtained from the daily waste of the boarding school kitchen and fruit waste, especially bananas at the Pagesangan market, as a source of glucose. The results obtained include one tub equivalent to 50 liters of organic compost fertilizer. The application of planting 1000 trees was carried out with a sample of ten kinds of plants with ten trees each in the PP Ittihadil Ummah environment in the form of vegetables, fruit trees, and leafy and ornamental plants..

ABSTRAKBiopolimer kitosan memiliki banyak aplikasi diantaranya sebagai biosorben, scaffold, bahan pengawet ikan, dan anti mikroba pada makanan. Dalam beberapa penelitian, kitosan sangat efektif dalam mengadsorpsi ion zat warna Metilen biru. Adapun tujuan dari penelitian ini untuk identifikasi karakteristik kitosan hasil isolasi dari cangkang kerang Mutiara. Proses isolasi biopolimer kitosan menggunakan metode deasetilasi bertahap. Dimana proses isolasi dilakukan dengan tiga proses yaitu deproteinasi, demineralisasi, dan deasetilasi. Serbuk hasil isolasi diidentifikasi rendemennya, diukur densitasnya, analisis gugus fungsi yang terbentuk dengan FTIR, dan menghitung kemampuan dalam mengadsorbsi zat warna metilen blue dengan Uv-Vis. Hasil penelitian menunjukkan bahwa kitosan yang dihasilkan berbentuk serbuk berwarna putih keabuan, rendemen 33,71%, densitas curah kitosan sebesar 1,21 gr/, serta didapat derajat deasetilasi dari kitosan sebesar 57,50 %. Efisiensi penyerapan zat warna Metilen biru oleh kitosan di setiap konsentrasi rata-rata bernilai 90 %. Oleh karena itu, biopolimer kitosansangat efektif dalam mengadsorbsi zat warna metilen blue. Kata kunci: deasetilasi bertahap; efisiensi penyerapan; karakteristik kitosan. ABSTRACTChitosan biopolymer has many applications including as a biosorbent, scaffold, fish preservative, and antimicrobial in food. In several studies, chitosan was very effective in adsorption of methylene blue dye ions. The purpose of this study was to identify the characteristics of chitosan isolated from pearl shells. The process of isolation of chitosan biopolymer uses the stepwise deacetylation method. Where the isolation process is carried out by three processes, namely deproteination, demineralization, and deacetylation. The isolated powder was identified its yield, measured its density, analyzed the functional groups formed by FTIR, and calculated the ability to adsorb methylene blue dye with UV-Vis. The results show that the chitosan is a grayish-white powder, the yield is 33.71%, the bulk density of chitosan is 1.21 gr/cm3, and the degree of deacetylation of chitosan is 57.50%. The absorption efficiency of methylene blue dye by chitosan at each concentration averaged 90%. Therefore, chitosan biopolymer is very effective in adsorbing methylene blue dye. Keywords: gradual deacetylation; absorption efficiency; chitosan characteristics.

Final year students are required to have the ability to innovate, be creative, have personality, and develop independence in seeking and finding knowledge through realities and field dynamics such as ability requirements, real problems, social interaction, collaboration, self-management, as well as performance demands and achievement targets. In order for students' hard skills and soft skills to be formed strongly, it is felt necessary to provide additional skills, especially those that support the completion of the Final Project. Workshops on the use of the Originlab are quite urgent in research so as to speed up the completion of the Final Project (Thesis) for students interested in Materials. This software is commonly used to prepare XRD, FT-IR, UV-Vis and other spectra that are quite important in materials. In this explanation, a brief description of the XRD data preparation steps is described, starting from data input to quantitative and qualitative data analysis. Data analysis was carried out including determining the value of particle size, FWHM, crystal structure and lattice strain. Workshop participants totaled 20 students and were held for 7 days, from 7 to 15 May 2023 with details of 2 days offline, 1 day online via G-Meet and 4 days of mentoring.

Fe is a type of heavy metal that can cause damage to the environment and health. If the concentrations of Fe are more than 1 mg/L, it can lead to toxic effects to the human body. The level of Fe contamination in the environment needs to be controlled to diminish hazardous effects. This can be conducted by modifying a smart material to adsorb the Fe metal. The material modification was carried out by isolating pearl oyster shells (Pinctada maxima) into chitosan as Fe metal adsorbent. The main aim of this research is to identify the ability of chitosan to soak Fe up. To obtain chitosan material, the pearl shells were isolated through 3 stages, namely deproteination, demineralization, and deacetylation. The isolated chitosan powder was identified the typical group forming chitosan using FTIR and the yield of each isolation process was calculated. Meanwhile, the ability of chitosan to adsorb Fe metal was identified through testing using AAS. The results of the calculation of the yield of the chitosan isolation process showed a decrease in mass at each stage. Until the final stage, the powder yield decreases to 32.17% from the initial mass used. In addition, the FTIR results also figure out that chitosan was successfully synthesized in the presence of the OH functional group at a wave number of 3434.660 cm-1 and the NH2 functional group at a wave number of 1626.110 cm-1 with a degree of chitosan deacetylation of 80.534%. It is clear from the results of AAS where the highest adsorption capacity is 33,262 mg/g with an adsorption efficiency of 99,788%. Therefore, the pearl shells have been successfully adjusted into chitosan. Where chitosan is one of the excellent biomaterials to absorb the heavy metal.
