Publisher : State University of Malang or Universitas Negeri Malang (UM)

Sekam padi merupakan limbah pertanian yang mengandung lignin sebesar (20-25%). Pelarut NaOH, etanol dan asam asetat merupakan pelarut yang umum digunakan dalam isolasi lignin karena menghasilkan lignin bebas sulfur dan kemurnian tinggi. Lignin berpotensi sebagai adsorben karena adanya gugus hidroksil dan cincin aromatik yang dapat berikatan dengan ion logam. Tujuan penelitian ini mengetahui pelarut terbaik dalam isolasi lignin sekam padi, mengetahui karakteristik lignin, dan menentukan kemampuan lignin sebagai adsorben logam Cd(II). Lignin hasil isolasi pelarut NaOH lebih efektif dan efisien karena menghasilkan rendemen dalam jumlah besar dibandingkan etanol dan asam asetat. Lignin hasil isolasi memiliki pita serapan pada daerah 3500-3200cm-1 yaitu peregangan O-H dan 1600cm-1 yaitu vibrasi kerangka aromatik serta memiliki bentuk morfologi permukaan bulat pada instrumentasi SEM. Lignin diaplikasikan sebagai adsorben Cd(II) dan memiliki kemampuan daya adsorpsi adsorben A dan B paling besar pada konsentrasi 2,0 ppm yaitu 1,037 dan 1,052 mg/g. Pemanfaatan lignin akan menaikkan nilai guna sekam padi sebagai adsorben logam berat.

Abstrak Ngadirejo adalah desa kawasan Tengger yang merupakan desa penghasil sayur wortel, kentang, kubis, sawi, dan bawang dengan jumlah masing-masing mencapai ±20 ton setiap masa panen. Dalam masa panen, 5-20% dari total panen adalah limbah sayur yang disebabkan oleh cacat pada sayur, dan sisa dari sortiran yang tidak bisa dikonsumsi oleh masyarakat. Rendahnya pengetahuan masyarakat terhadap pengolahan limbah organik menyebabkan limbah sayur menjadi penyumbang sampah terbesar di kawasan Tengger. Tujuan program pengabdian ini adalah mengurangi populasi sampah organik Desa Ngadirejo dengan cara mengolah limbah sayur sebagai pupuk organik cair (POC). Program ini dilakukan dalam bentuk sosialisasi, pelatihan, praktek pengolahan limbah sayur sebagai POC terhadap gabungan kelompok tani (GAPOKTAN), analisis kandungan unsur pada POC dalam lingkup laboratorium, serta pendampingan aplikasi POC sebagai pengganti pupuk kimia (PK) dalam penanaman sayur. Hasil program ini terbukti dapat menurunkan jumlah sampah sayur secara drastis, meningkatkan pengguna POC dan secara kualitatif produk POC memiliki unsur hara lebih banyak dari PK. Abstract Ngadirejo is a village in the Tengger area that produces ± 20 tons each of carrots, potatoes, cabbage, mustard greens, and shallots. During the harvest period, 5-20% of the total harvest is vegetable waste caused by defects in the vegetables, and the rest of the sort can no longer be consumed. The low level of public knowledge about organic waste processing has made vegetable waste the biggest contributor to waste in Tengger. This program aims to reduce the organic waste population in Ngadirejo by processing vegetable waste as liquid organic fertilizer (LOF). This program is carried out in form of socialization, training, and practice of processing vegetable waste as LOF to farmer, elemental analysis within the scope of the laboratory, and monitoring the application of LOF as a substitute for chemical fertilizers (CF) on vegetable cultivation. The results of this program have been shown to drastically reduce the amount of vegetable waste, increase LOF users, and qualitatively LOF products have more nutrients than CF.

Batik is a characteristic Indonesian textile product. The color of batik is one component that affects the quality of batik. Various types of batik dyes, one of which is remazol dyes. Remazol dyes are synthetic dyes that have strong chemical bonds. This is what underlies the process of production of the household batik industry in the village of Purwosekar, District of Tajinan, Malang Regency, with remazol coloring will produce liquid waste that is difficult to be deciphered naturally. This study aims to provide a water treatment solution using the coconut shell activated carbon adsorption method with chemical activation and the ability to adsorb remazol dyes. Adsorption experiments were carried out in batches with a mesh size of 8 with coconut shell carbon activated with 1 M HCl solution for 24 hours. The absorption of remazol dyes by coconut shell activated charcoal is carried out with a stirring speed variation for 60 minutes and the mass of activated charcoal to find the optimum adsorption conditions. Stirring speed variations are 30 rpm, 60 rpm, and 90 rpm, resulting in the highest efficiency at a speed of 90 rpm. While the variations in mass are 200 grams and 300 grams, the highest efficiency is obtained with a mass of 300 grams. Thus, the efficiency of the coconut shell activated carbon is proportional to the stirring speed and mass of the coconut shell activated carbon used

The beach is an attractive place to unwind from your daily routine. The beauty of the beach must always be maintained so that comfort can still be obtained for everyone who visits it. The beach becomes a comfortable place if cleanliness is maintained. Plastic waste, if any along the coast, can be carried by the waves into the ocean. Plastic waste brought to sea can be consumed by marine biota because marine biota cannot distinguish between plastic and food waste. This community service activity intends to inspire visitors (tourists), managers and traders at Balekambang beach to care about the environment. A well-preserved environment will be a legacy that will be left on the next generation. The survey results show that visitors understand the meaning of waste and are willing to dispose of waste in its place. DOI: https://doi.org/10.26905/abdimas.v5i2.3573

Surfactants are organic materials that act as active ingredients in detergents, soaps and shampoos which can reduce the surface tension of the water so that the particles attached to the materials being washed are released and float or dissolved in water thus polluting the environment. Therefor it is necessary to separate or change them into other harmless materials before being discharged into the environment. One of the methods used is electrocoagulation. The electrocoagulation method is an environmentally friendly method of treating liquid waste by combining the principles of coagulation, flotation and electrochemistry. In this study, the electrocoagulation method was carried out by varying pH and electrolyte concentrations in the simulated surfactant waste treatment. Surfactant levels were determined by spectrophotometer in methylene blue. The optimization of the method is done by determining the maximum absorption length, optimum pH, and the effect of adding electrolytes with different concentrations. The results showed that the maximum absorption at a wavelength of 659 nm. The electrocoagulation process runs optimally at pH 2 with the addition of 7mM Na2SO4 electrolyte resulting in a% removal of 65%.

An analytical method was carried out to identify volatile compounds that play a role in the coffee aroma and their stability. Because it is unstable at high temperatures, the effect of the injection temperature on the GC/MS column on changes in compounds profile was observed. The aim of this research is also to develop analytical methods for coffee analysis using TPI-GC/MS method. Samples of Lemar Arabica coffee were taken from the Wonosantri Abadi plantation, Singosari, Malang, and roasted at 210°C. The roasted coffee was extracted using the soxhletation method and methanol as solvent. The compound profiles were analyzed using the GC/MS method with injection temperatures of 40°C, 140°C, and 240°C. The results showed that ketones, esters, furans, and thiazoles play a role in the aroma of coffee. The compounds present in roasted coffee injected at 40°C were less than those at injection temperatures of 140°C and 240°C based on the chromatograms. The profile of the compound at the injection temperature of 240°C is also more diverse than the others because the large injection temperature allows decomposition to occur so that there are many fractional compounds from the thermal decomposition. Toluene is the most stable compound because it appears at all three injection temperatures. Non-volatile caffeine compounds were also detected at an injection temperature of 240°C.

The banana plant that is still underutilized compared to the fruit part is the heart of the banana. Even though the heart of the banana has many benefits and nutritional content that is good for health. Seeing the potential of the heart of the banana can improve public health, so food diversification efforts such as flour and substitutes for the basic ingredients of food to produce new forms of product innovation, so research was carried out to test its content, which aims to inform the public that the heart of the banana can be beneficial for health in processing into flour. This research was carried out in March-April 2022 at the Chemistry Education Laboratory of Nusa Cendana University, Kupang. There are four stages in this study, including 1) Manufacture of the heart of banana flour; 2) Proximate Test of the heart of banana flour; 3) Diversification of products based on the heart of banana flour, 4) Organoleptic test of products based on the heart of banana flour on 52 panelists. The results of research on the manufacture of banana heart flour are substituents of flour that have good nutritional content with relatively good character if used as a substitute for wheat flour because many parameters meet the quality requirements of wheat flour, namely the physical characteristics of banana heart flour meet the test requirements for shape. In contrast, the aroma, color, and taste in accordance with the characteristics of the nutritional content meet the moisture content proteins, fats, and carbohydrates. In contrast, the ash content does not complete because the mineral content in each ingredient is different and the manufacture of wheat flour. The result of the diversification of the products made, namely the Genital Widow Cake / Monde chips made from banana heart flour, are also included in the excellent category where the aroma, taste, and acceptance of the product are accepted in the community.
