Abstract

Currently, paper demand in the world has reached 394 million tons/year, while in Indonesia paper consumption has reached ± 8.9 million tons/year. As demand for pulp increases, paper production in Indonesia also needs to be increased. Paper products are produced from fibrous raw materials such as wood. The reduced availability of wood means that demand for wood raw materials cannot be met. This encourages the pulp and paper industry to look for sources of fiber. One natural resource that is easy to manage as a substitute raw material for the pulp and paper industry is water hyacinth. In this research, the delignification process of paper from water hyacinth was carried out using sodium hydroxide to determine the effect of NaOH on the manufacture of packaging paper with fixed variables, namely cooking temperature 100C, water hyacinth 60 gr, chlorine and starch 2gr each, and the variable changing the concentration of NaOH 2%, 2,5%, 3% with a cooking time of 90 minutes, 100 minutes and 110 minutes to obtain a paper tensile strength of 4,683 kN/m2, paper weight (gramatur) of 70 gr/m2 with a paper thickness of 0,7 mm. Abstrak Saat ini kebutuhan kertas didunia mencapai 394 juta ton/tahun sedangkan di Indonesia konsumsi kertas mencapai ± 8,9 juta ton/tahun. Bertambahnya kebutuhan pulp maka produksi kertas di Indonesia juga perlu dilanjutkan. Produk pulp dihasilkan dari bahan baku yang berserat seperti kayu. Berkurangnya ketersediaan kayu mengakibatkan permintaan bahan baku kayu tidak bisa dipenuhi. Hal ini mendorong indutri pulp dan kertas mencari sumber serat. Salah satu sumber daya alam yang mudah dikelolah sebagai bahan baku subtitusi industri pulp dan kertas adalah eceng gondok. Pada penelitian ini dilakukan proses delignifikasi kertas dari eceng gondok menggunakan katalis Natrium Hidroksida untuk mengetahui pengaruh NaOH terhadap pembuatan kertas kemasan dengan variabel tetap suhu pemasakan 100, eceng gondok 60 gr, kaporit dan tepung kanji masing-masing 2 gr dan variabel berubah konsentrasi NaOH 2%, 2,5%, 3% dengan lama waku pemasakan 90 menit, 100 menit dan 110 menit sehingga diperoleh kuat tarik kertas 4,683 kN/m2, berat kertas (gramatur) 70 gr/m2 dengan ketebalan kertas (Thickness) 0,7 mm.

Abstract

Using bioplastics as a substitute for plastics that decompose more slowly is one way to overcome the problem of plastic waste. Natural polymers are the basic ingredients of biodegradable plastics, or bioplastics. Water and microorganisms are two tools that can be used by the environment to break down bioplastics. The main qualitative research methods in this research are observation of test phenomena, biodegradation assessment, and water absorption capacity assessment. Biodegradation tests measure the rate at which microorganisms or the environment degrades biodegradable polymers. To find out how effectively plastic decomposes, samples of biodegradable plastic are planted in the soil. Based on samples with glycerol sorbitol content of 15%, 20% and 25%. The 15% concentration group experienced damage or weight loss more quickly compared to samples containing 20%, 25% and 15% glycerol. One thing that is taken into account in evaluating the quality of bioplastics is their ability to absorb water. Because it is related to how long plastic can last in storage, the greater the water absorption capacity of a bioplastic, the worse its quality. From the analysis of biodegradation and water absorption tests, the lower the concentration of glycerol and sorbitol, the more fragile the plastic produced, less elastic, and more easily decomposed by water, soil and other microorganisms. The higher the concentration of glycerol and sorbitol, the higher the results obtained. The plastic produced will be harder so that it is not easily decomposed or damaged.

Abstract

Maharani Zoo & Goa di Kabupaten Lamongan memiliki permasalahan utama yaitu pembuangan kotoran hewan gajah dan hewan lainnya dalam jumlah yang relatif besar yaitu ±30 ton per bulan. Permasalahan limbah bolga ini belum mendapatkan solusi optimal sehingga hanya ditimbun di lokasi khusus tanpa adanya pengolahan lebih lanjut. Oleh karena itu, program ini bertujuan untuk mengolah potensi limbah kotoran gajah atau bolga menjadi produk-produk bernilai ekonomis dengan memanfaatkan teknologi dalam rangka mendukung program green economy. Metode yang digunakan dalam pengolahan bolga adalah menggunakan proses pirolisis untuk pembuatan produk briket dan pupuk organik padat, serta proses fermentasi untuk pembuatan pupuk organik cair. Adapun hasil dari kegiatan ini antara lain produk briket, pupuk organik padat dan pupuk organik cair, kerjasama antara perguruan tinggi dengan mitra, serta dokumen SOP pengolahan bolga. Sehingga dapat disimpulkan bahwa proses pengolahan bolga menjadi tiga produk tersebut telah membantu mitra mengatasi permasalahan limbah kotoran hewan.

Abstract

Furfural is a selective solvent for petroleum that can produce high-quality diesel fuel. Generally, furfural research uses raw materials from corn cobs, but most still use inorganic acid catalysts. Therefore, researchers are trying to find alternative catalysts using environmentally friendly organic acids from Averrhoa bilimbi extract. This research aims to determine the effect of the concentration of sulfuric acid catalyst and Averrhoa bilimbi extract in the hydrolysis process on the quality and yield of furfural and the impact of using microwave heating on the quality and yield of furfural produced. The method used to make furfural is hydrolyzing corn cobs using a microwave heater (400 Watt power) with various sulfuric acid catalyst concentrations (10%, 15%, and 20%) and Averrhoa bilimbi. Observe the number of yields at each time interval of  60, 75, and 90 minutes. The resulting furfural is then analyzed to calculate the yield of each sample and identify furfural compounds using Gas Chromatography-Mass Spectrometry (GCMS). The research results showed that the best furfural yield at a catalyst concentration of 10% H2SO4 with a time of 90 minutes was 14.9632%. In GCMS analysis, the compound peaked on gas chromatography at a retention time of 2.208 with a relative molecular mass of 83.

Abstract

A social welfare institution serves as a substitute for parents or guardians in fulfilling the physical, mental, and social needs of children under its care, while also introducing activities that support economic independence. A community service initiative, in the form of a series of workshops on the production of YOSS (Healthy Squeezable Yogurt), has been designed as an effort to empower partnerships that enhance both the health and economic strength of the institution. This community service program is conducted over a one-year period, with active mentoring provided for three months, from July to Seotember 2024, targeting the caregivers and 55 residents at Sunan Ampel Orphanage (PASA) in Malang City. The mentoring covers various aspects, including production, consumption, packaging, and marketing. PASA possesses significant potential for developing this enterprise, supported by a young workforce and available basic facilities. However, challenges remain in improving production quality, particularly in maintaining the sterility of equipment and products. The production of YOSS has the potential to be further developed into a flagship product through expanded marketing and distribution efforts.

Abstract

A social welfare institution functions as a substitute for parents or guardians by fulfilling the physical, mental, and social needs of the children under its care, while also promoting activities that foster economic independence. A community service initiative, implemented through a series of workshops on the production of Healthy Squeezable Yogurt, was designed to strengthen partnerships that support both the health and economic sustainability of the institution. The program was conducted over a one-year period, with intensive mentoring provided for three months from July to September 2024 targeting caregivers and 55 residents of the Sunan Ampel Orphanage in Malang City. The mentoring sessions covered several key areas, including production, consumption, packaging, and marketing. After three months of implementation, 80% of the students were reported to consume yogurt regularly, while 91% experienced no health-related problems. Furthermore, the students demonstrated the ability to produce yogurt independently and accurately. It is recommended that the product packaging be further enhanced to increase its visual appeal, that marketing efforts be expanded through social media platforms, and that regular cooking shifts be established to promote the long-term business sustainability.
