Abstract

Sukrosa merupakan disakarida umum yang banyak digunakan dalam berbagai industri, termasuk industri molase. Sukrosa dapat dihidrolisis menjadi fruktosa dan glukosa dengan bantuan enzim invertase. Gula invert sangat dibutuhkan dalam industri karena memiliki tingkat kemanisan yang lebih tinggi dibandingkan sukrosa. Enzim invertase berperan penting dalam proses pemecahan sukrosa tersebut. Penelitian ini bertujuan untuk mengevaluasi hubungan antara aktivitas enzim invertase dengan variasi konsentrasi substrat, pH, suhu, serta pengaruh penghambatan aktivitas enzim oleh CuSO₄. Tahapan penelitian dimulai dengan penyiapan larutan enzim invertase sebesar 0,04 g/L dan larutan sukrosa. Selanjutnya dilakukan pengujian terhadap pengaruh variasi konsentrasi substrat (0,0–3 mL), pengaruh pH (rentang pH 3 hingga pH 9), pengaruh suhu (18 °C, 30 °C, dan 95 °C), serta pengaruh penghambatan oleh CuSO₄ pada konsentrasi sukrosa 50 g/L dan 200 g/L terhadap aktivitas enzim invertase. Hasil penelitian menunjukkan bahwa pemecahan sukrosa oleh enzim invertase memiliki pH optimum pada kisaran 3–4,5. Suhu optimum aktivitas enzim berada pada 30 °C. Peningkatan konsentrasi substrat menghasilkan peningkatan aktivitas enzim, ditandai dengan meningkatnya kadar gula pereduksi. Enzim menunjukkan aktivitas yang lebih tinggi ketika jumlah substrat meningkat karena lebih banyak substrat yang dapat berikatan dengan sisi aktif enzim. Peningkatan konsentrasi CuSO₄ menunjukkan korelasi positif dengan peningkatan kadar gula sisa, yang mengindikasikan efek penghambatan terhadap aktivitas enzim.

Abstract

Limau Manis Village as Kampung Manggis is supported by the production of mangosteen in Padang City which is number 2 (two) in West Sumatra and 80% of mangosteen in Padang City comes from Pauh Subdistrict, with the center being in Limau Manis Village and the existence of Kampung Manggis brings hope for the community to improve their economy and will have an impact on the economy of the Padang City community. The skin of mangosteen fruit can be processed into value-added products. However, farmers and local businesses still face several challenges, such as the lack of knowledge and technology to process mangosteen peels into economically valuable products. Abundant mangosteen peels during the harvest season are often discarded or burned, causing environmental impacts such as soil and air pollution. However, due to the lack of public knowledge on mangosteen peel processing as waste, an innovative solution is needed to turn mangosteen peel waste into a new source of income through the development of competitive derivative products. This community service activity is designed as a strategic step to empower the community, optimize local potential, and build an innovative, sustainable mangosteen agroindustry, creating value-added products and improving the economic welfare of the community. In addition, this activity is also expected to be a model of agroindustry development based on local potential that can be developed. The purpose of this community service activity is to provide training in improving the knowledge, skills of the community in processing mangosteen skin, increasing the added value of mangosteen skin into mangosteen skin tea and mangosteen skin syrup products that have a broad impact on economic, social and environmental improvement.

Abstract

Peanuts are one of the leading commodities of Nagari Tigo Balai, Matur District, Agam Regency, West Sumatra. Some people in Nagari Tigo Balai have processed peanuts into rendang peanuts and many still sell their raw peanuts directly from their harvest. The processed peanuts from Nagari Tigo Balai craftsmen are still packaged in ordinary packaging, namely using transparent plastic and makeshift labels. This activity aims to provide assistance to the peanut MSMEs of Nagari Tigo Balai to produce packaging according to the target market. This activity is carried out in several stages, namely socialization, packaging design, and assistance in the use of packaging. One of the productive peanut MSMEs in Nagari Tigo Balai is the LBM MSMEs. The assistance activity has produced three packaging designs, namely the PP standing pouch packaging design, the PP plastic packaging sticker label design, and the PP plastic packaging screen printing label design. The most suitable and needed packaging design for the rending peanut craftsmen of LBM MSME Nagari Tigo Balai is the sticker label on PP plastic packaging. The chosen design is consistent with the target market of rendang peanuts produced by LBM MSME Nagari Tigo Balai, which includes consignment system at souvenir outlets, direct sales in nearby markets, and distribution through local traders.

Abstract

Sago liquid waste contains high levels of carbohydrates and has potential as a fermentation medium for bacterial cellulose production. However, its nutritional content requires enhancement by supplementing it with tea waste to achieve optimal yields. This study investigated the effect of varying tea waste additions on the characteristics of bacterial cellulose produced from kombucha fermentation based on sago liquid waste. The research method used a completely randomized design with five treatments (2, 4, 6, 8, and 10 g of tea dregs) and three replications. The observed parameters included yield, thickness, moisture content, cellulose content, and Fourier Transform Infrared (FTIR) spectroscopy. The results showed that increasing tea waste levels significantly affected all parameters (p < 0.05). The best treatment (10 g) resulted in a yield of 18.21%, a thickness of 13.47 mm, a moisture content of 47.57%, and a cellulose content of 52.43%. FTIR spectral analysis confirmed the characteristic peaks of bacterial cellulose, indicating the presence of crystalline β-1,4-glucan structures. The identification of cellulose type I is significant because it represents the native crystalline form of bacterial cellulose, which is associated with high mechanical stability, strong hydrogen bonding, and potential suitability for biopolymer applications. This study demonstrates that tea waste is an effective nutrient supplement that enhances the quality and quantity of bacterial cellulose derived from kombucha fermentation of sago liquid waste.

Abstract

Bioplastics are one of the alternatives to replace synthetic plastics. Bioplastics are plastics made from natural materials readily decomposed by microorganisms so that they are environmentally friendly. Oil Palm Empty Fruit Bunches (OPEFB) have cellulose content that can be utilized as raw material in the manufacture of bioplastics. This research aims to determine the best formulation of OPEFB cellulose-based bioplastics as environmentally friendly packaging. The method used in this research is the Response Surface Methodology (RSM) optimization method in the Mixture (Optimal Custom Design) section found in the Design Expert version 13 application. The factors analyzed in making bioplastics are glycerol, starch, CMC, and chitosan. Bioplastic observations include tensile strength, elongation, elasticity, thickness, water resistance, and biodegradation. The result of OPEFB cellulose obtained in this study is 71.88%, where the cellulose produces strong bioplastic properties. The optimum solution of bioplastic formulation produced is the addition of glycerol of 0.89 g, starch of 2.99 g, CMC of 2.11 g, and chitosan of 3 g Laboratory verification responses produced are tensile strength of 12 MPa, elongation of 31.34%, elasticity of 890.67 MPa, thickness of 0.25 mm, water resistance of 88.95%, and biodegradation of 4.34%/day.
