Penelitian ini bertujuan untuk mempelajari pengaruh penambahan volume kitosan sebagai adsorben dari cangkang bekicot (AchatinaFullica) terhadap keefektifan kitosan dalam menjerap logam tembaga (Cu) dalam air lindi. Pembuatan kitosan terdiri dari tahap deproteinasi dengan natrium hidroksida 2 N, tahap demineralisasi dengan hydrogen clorida 1 N, serta tahap deasetilasi dengan Natrium hidroksida 50%. Campuran dipanaskan dengan hot plate pada suhu 90oC selama 1 jam dan diaduk menggunakan magnetic stirrer. Larutan dipisahkan dan dikeringkan didalam oven untuk mendapatkan kitosan. Hasil analisa Fourier Transform Infra Red (FTIR) menunjukkan bahwa derajat deasitilasi kitosan adalah sebesar 89.6%. Kitosan dilarutkan dalam air untuk menghasilkan larutan dengan konsentrasi 10.000 ppm. Berbagai volume kitosan (2, 4, 6, 8 dan 10 mL) dicampurkan kedalam 1 L air lindi dan diaduk selama 15 menit. Kadar Cu pada sampel air lindi diuji menggunakan Atomic Absorption Spectrophotometric (AAS). Diperoleh hasil bahwa daya serap terhadap kadar Cu terbaik, yaitu 34,46%, adalah pada penambahan kitosan sebanyak 10 mL.

Disposal of laundry waste directly in the river is the cause of high river pollution. Laundry wastewater resulted in an increase in BOD and COD parameters so that it had a negative impact on ecosystem life. The coagulation process using chemicals can reduce BOD and COD parameters in wastewater but have negative effects on health. Chitosan from snail shells can be used as an alternative coagulant that is environmentally friendly because it contains about 70% - 80% chitin. This study aims to synthesize chitosan biocoagulants from snail shells and to test the effectiveness of snail shell chitosan in the treatment of laundry wastewater. Fourier Transform Infra-Red (FTIR) analysis showed that the deacetylation rate of chitosan obtained was 78.06%. Coagulation was carried out on wastewater using variable concentrations and stirring speed. The results showed that the optimum dose of snail shell chitosan biocoagulant was at a concentration of 0.4%. At this dose, the coagulant can bind to the most optimal contaminants so that it can reduce the BOD and COD values â€‹â€‹in laundry waste and the Fast Stirring Speed â€‹â€‹of 100 rpm is the optimum stirring speed because large speeds will produce excessive shear forces and prevent the desired floc arrangement.

Air payau adalah air yang salinitasnya lebih rendah dari pada salinitas rata-rata air laut normal (<35 permil) dan lebih tinggi dari pada 0,5 permil yang terjadi karena pencampuran antara air laut dengan air tawar baik secara alamiah maupun buatan. Tujuan dari penelitian ini yaitu Menentukan jumlah penambahan optimum kitosan dari cangkang bekicot (Achatina Fulica) untuk mendapatkan penurunan kadar garam air payau terendah dan menentukan waktu optimum pengadukan yang dibutuhkan untuk mendapatkan penurunan kadar garam air payau terendah agar mengetahui potensi penggunakan kitosan dari cangkang bekicot (Achatina Fullica) sebagai absorpben salintas air payau. Kitosan dilarutkan dalam asam asetat 1% dan aquades dengan konsentrasi 1.000 mg / L. Dibuat sampel campuran larutan kitosan dan air payau dengan variasi konsentrasi dari 0 hingga 3.85% volume tetap yaitu 260 ml dan diaduk selama 20 menit. Kadar Salinitas dalam sampel air payau diuji menggunakan alat Salonimeter. Hasil yang diperoleh menunjukan bahwa Kitosan Cangkang Bekicot mampu berperan sebagai absorpben salinity air payau dan ini dibuktikan berdasarkan efisiensi yang dihasilkan pada penurunan salinity sebesar 5,78% untuk kitosan asam asetat 1% dan penurunan salinity sebesar 8,09% untuk kitosan aquadest. Sedangakan untuk lama waktu pengadukan selama 40 menit merupakan waktu pengadukan yang optimum.

Abstract Newspaper is one of the mass media that is often used by the public but has the potential to produce the most dominant paper waste. Based on data from the Balikpapan Kaltim Tribune in 2016, the number of printed newspapers for the province of East Kalimantan reached 635,538 tons per year. Based on the dry substrate, newspaper contains 42.2% cellulose; 24.85% hemicellulose and 23.07% lignin which can be utilized and have higher economic value when hydrolyzed into glucose in the manufacture of bioethanol. This study aims to determine the optimum temperature and time of the ultrasonic wave-assisted newspaper hydrolysis process. This research was carried out by hydrolyzing 100 grams of newspaper powder and dissolved in 600 ml of 1% H2SO4 using 28kHz ultrasonic waves with temperature variations (60°C, 70°C, 80°C and 90°C) and time variations (10 minutes, 20 minutes). , and 30 minutes). The resulting glucose was analyzed using the Luff Schoorl method. The results of this study showed that the highest glucose level of 2.3994 mg/g was obtained at a temperature of 80°C and a hydrolysis time of 10 minutes. Keywords: glucose, hydrolysis, newsprint, ultrasonic

Corona virus disease (Covid-19) is a disease caused by a virus that attacks the respiratory tract and still continues today. The death toll from Covid-19 continues to rise in Indonesia as the number of positive cases of the coronavirus reaches thousands of people. One of the bacterial infections that cause respiratory infections is Klebsiella pneumoniae. One of the preventive efforts to prevent the spread of infections caused by the corona virus and bacteria is the renewal of waterless hand sanitizers called antiseptic hand sanitizers or hand sanitizers. The approach method used is to provide understanding to the students about the potential of waste treatment in the city of Bontang. Continue by socializing the manufacture of chitosan from shrimp shells and the process of processing chitosan to produce hand sanitizers. From the results of this training, it can be concluded with enthusiasm from the students that the activities are carried out well and are able to increase students' knowledge about the potential of waste in the surrounding environment and it is hoped that they will be able to practice making hand santizers on a simple scale. Keywords: Chitosan, Hand Santizer, Alcohol-Free, Islamic Boarding School Students.

Desalination (removal of salt content) of salt or brackish water into fresh water is another way to obtain fresh water. The two most widely practiced methods are distillation (distillation), heating seawater until it evaporates and then condensing to get fresh water and reverse osmosis, seawater at high pressure through a thin membrane to pass water molecules. Another method that can be used in the desalination process is the adsrobtion process. One of the media that can be used in the adsrobtion process is chitosan. This research is carried out by the bacth method with two variables, the first variable concentration, namely 800, 1600, 2400, 3200 and 4000 ppm. The second variable is the stirring time with variations, namely 100, 200, 300, 400 and 500 rpm. Based on the results of studies that have been carried out, the best concentration of shrimp skin chitosan is at a concentration of 4000 mg / L or the addition of 200 mg of chitosan in 0.25 L of brackish water. At this concentration, the absorbent can reduce the salinity of brackish water by 86.6694% and for the best stirring speed the shrimp shell chitosan is at a speed of 300 rpm with the addition of 1000 mg of chitosan in 0.25 L of brackish water. At this stirring speed, the adsorbent can reduce the salinity of brackish water by 82.6335%.
