Abstract

Green tea offers numerous health benefits; however, its market sales remain relatively low. PT Mitra Kerinci, the producer of the Likicha brand green tea, reported that only 38% of its annual production was absorbed by the market. This situation underscores the need for a strategic development plan to enhance sales performance. Therefore, an integrated approach combining PLS-SEM, BMC, QFD, and AHP methods was employed to formulate a strategy to increase the sales volume of Likicha green tea. This study aimed to identify consumer preferences for green tea products to develop a product strategy that enhances market absorption. The findings of this study indicate that consumer purchase intentions for green tea are influenced by health benefits, product packaging attributes, and price. A business mapping of the green tea industry was conducted to obtain a comprehensive internal and external analysis. The QFD data analysis identified technical requirements and prioritized component needs for improving green tea production. These results were then used to formulate criteria and strategic alternatives aimed at increasing green tea sales volume. The results indicate that product quality holds the highest priority among the criteria, with a weight of 64.3%. Among the strategic alternatives, sourcing high-quality tea leaves and optimizing processing methods emerged as the top priority, with a weight of 26.2%.

Abstract

Tujuan dari penelitian ini adalah untuk merumuskan alternatif strategi penerapan prinsip produksi bersih pada industri tahu di Kota Padang, serta meningkatkan efisiensi penggunaan sumber daya (bahan mentah, energi, dan air) sekaligus mereduksi dampak lingkungan dari produk yang dihasilkan. Penelitian ini menggunakan metode analisis deskriptif berdasarkan data primer yang diperoleh melalui wawancara dan observasi langsung, serta didukung oleh data sekunder yang diambil dari jurnal ilmiah dan sumber relevan lainnya. Hasil penelitian menunjukkan bahwa berdasarkan pengukuran neraca massa yang dilakukan pada industri tahu skala rumah tangga, proses produksi menghasilkan limbah cair sebesar 874,5 kg. Limbah cair yang dihasilkan ini dapat dikurangi melalui penerapan prinsip produksi bersih, khususnya dengan tindakan good housekeeping dan pemanfaatan kembali air pada proses pencucian dan perendaman kedelai. Upaya pengelolaan limbah cair dari sisa pencucian dan perendaman dilakukan melalui proses inkubasi di kolam berukuran 10 x 10 x 5 meter yang diaktivasi dengan mikroorganisme merek BIOS. Penerapan strategi ini diharapkan dapat meningkatkan efisiensi proses produksi, mengurangi beban pencemaran lingkungan, serta menjadi model pengelolaan limbah yang berkelanjutan bagi industri sejenis di wilayah lain.

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

Biodegradable plastic is a type of plastic that undergoes biodegradation at a significantly faster rate than conventional plastic and is composed of renewable raw materials. The primary raw material used in the production of biodegradable plastic is polysaccharides derived from starch that has undergone gelatinization. In this study, cassava starch was selected as the base material. The use of starch as the main component in biodegradable plastic production is a viable alternative due to its abundant availability, ease of decomposition, and relatively low cost. However, starch-based biodegradable plastic has a major drawback—its low mechanical strength. To address this limitation, plasticizers and other additives are incorporated to enhance the elasticity of the resulting plastic. This study aims to analyze the effect of sorbitol plasticizer concentration on the physical and mechanical properties of biodegradable plastic, determine the optimal concentration of sorbitol plasticizer to achieve the best biodegradable plastic properties, and assess the added value of the resulting biodegradable plastic. The research methodology employed a Completely Randomized Design (CRD) with five treatments and three replications. If significant differences were observed, further analysis was conducted using Duncan’s New Multiple Range Test (DNMRT) at a 5% significance level. The findings indicate that the addition of sorbitol plasticizer significantly influences the physical and mechanical properties of biodegradable plastic. The optimal treatment was observed with a 40% sorbitol plasticizer concentration, yielding an average thickness of 0.23 mm, a water vapor transmission rate of 11.45 g/m²·h, a biodegradability rate of 62.12% over two weeks, water resistance of 35.47%, tensile strength of 0.56 MPa, elongation of 23.98%, and elasticity of 0.03 MPa. The added value obtained was Rp 90,376/kg, with a value-added ratio of 63.11%.

Abstract

Bioplastik meruapakan kemasan yang dapat diuraikan oleh lingkungan secara alamiah. Limbah cair tahu yang memiliki kandungan bahan organik seperti protein yang tinggi dapat dimanfaatkan sebagai bahan baku bioplastik. Penggunaan limbah cair tahu sebagai bahan pembentuk bioplastik belum menghasilkan bioplastik dengan karakteristik yang baik. Oleh karena itu, pada produksi bioplastik diperlukan bahan penyusun lainnya, diantaranya gliserol sebagai plasticizer. Penelitian ini bertujuan untuk mengkaji pengaruh variasi penambahan gliserol terhadap karakteristik bioplastik yang dihasilkan. Penelitian ini menggunakan rancangan acak lengkap dengan 5 perlakuan dan 3 kali ulangan. Jika terdapat perberbedaan yang nyata, maka dilanjutkan dengan Duncan’s New Multiple Range Test pada taraf nyata 5%. Hasil penelitian menunjukkan bahwa variasi penambahan gliserol berpengaruh nyata terhadap nilai kuat tarik, elongasi, elastisitas, daya serap air, dan biodegradasi bioplastik yang dihasilkan. Penambahan gliserol 7% merupakan perlakuan terbaik dengan rata-rata nilai ketebalan 0,175 mm, kuat tarik 12,2 MPa, elongasi 15,93%, elastisitas 0,76 MPa, daya serap air 52,54%, dan biodegradasi 8,26%/hari.

Abstract

The objective of this study is to investigate the distinctive properties of activated carbon derived from cocoa pod husks that have been activated using various activators. The study seeks to assess the absorption capacity of the resulting activated carbon for the heavy metal Fe, and to identify the most effective activator for this purpose. The activators used were ZnCl2, H3PO4, KOH, and MgCl2 each at a concentration of 10%. The characteristics of the activated carbon produced include; yield 70.18–82.24%, water content 0.75–2.25%, ash content 3.50–11.00%, part lost on heating 950? or volatile matter 9.38–15.61 %, pure activated carbon of 76.94–79.16%, and absorption of iodine of 574.36–628.30 mg/g. The utilization of activated carbon derived from cocoa pod husks has demonstrated its efficacy in the adsorption of the heavy metal iron (Fe) present in well water. This adsorption process exhibits a notable absorption capacity within the range of 0.0967–0.0991 mg/g, accompanied by a high absorption efficiency ranging from 96.62% to 99.02%. The most effective activator, as determined by its iodine number, was found to be potassium hydroxide (KOH), which exhibited an impressive absorption capacity of 628.30 mg/g of iodine. On the other hand, magnesium chloride (MgCl2) emerged as the most economically viable activator, with a price of Rp. 30,00 per gram.

Abstract

The research results show that: (1). All liquid waste requirements for land application have been fulfilled properly, even the biodegradation results in anaerobic ponds are much smaller than those required by Environmental Impact Control Agency, (2). Water quality standards in monitoring wells in gardens are based on PP No. 82 of 2001 Class II, BOD-5 and Total Nitrogen do not meet quality standards, but at the resident monitoring well location almost all parameters tested meet quality standards, COD is smaller and even oil and fat are not detected and the Total Nitrogen content is only 2.38 mg/l which has met the requirements. Waste seepage into residents' wells is not significant; (3). The results of plantations that use land applications and non-land applications are different, where the results of gardens that use liquid palm oil mill waste as land applications produce much greater fruit production (average yield is greater/ha 48.28%) than the results of oil palm plantations. (4). The use of fertilizer on land application land was initially greater than on land that did not use land application land, this was because agricultural yields had actually started to decline because they were over 20 years old, but the use of fertilizer was decreasing every year, and (5). The oil content of fresh fruit bunches (FFB) applied to garden land and non-land application shows a difference in oil content, where fresh fruit bunches (FFB) applied to garden land on average have a greater oil content than fresh fruit bunches. (TBS) non land garden application
