Abstract

The traditional food products of nisan and oluo are local heritage items obtained through the process of menggelek tobu. As local products, nisan and oluo have rich and distinctive cultural value. This study intends to explore the significant role that labeling and packaging design have in promoting and spreading local culture to the larger community, as well as in improving the perception of local nisan and oluo. Incorporating cultural components such as symbols, theme colors, patterns, and language into packaging design can give it a distinctive personality and attract customers. When packaging design effectively portrays the cultural richness and history of a region, local products like nisan and oluo become more appealing and instill a sense of pride in the local community. The results indicate that using cultural information on packaging design and labeling containing cultural information can be a useful strategy improving the perception of local nisan and oluo food products and bringing culture to a larger audience. In the era of globalization, efforts to preserve cultural diversity and promote local products should be recognized and strengthened through smart and sustainable packaging design. Local products can therefore be a powerful representation of valuable cultural identity and contribute positively to the economy and cultural awareness both nationally and internationally.

Abstract

Food additives are compounds that are deliberately added to food in certain quantities and sizes and are involved in processing, packaging and/or storage. Food additives are mixed ingredients that are not part of the food raw materials, but are added to food to influence the nature or shape of the food, including colorings, preservatives, flavorings, anti-caking agents, whiteners and thickeners. Most people use food additives without clear measurements, which will have negative consequences for people's health. Therefore, outreach activities are needed to the public regarding the proper and correct use of food additives. The aim of this service activity is to provide information about food additives to the community, especially the community in Pagaruyung village, Tapung District, Kampar Regency. With these service activities and publications, it will help disseminate information regarding the correct use of food additives. Before public outreach, a pre-test was given, where the level of public understanding regarding BTP was 60%. After presenting the BTP material, a post test was carried out where public understanding increased to 92%. For evaluation of the implementation of community service activities, almost all people felt the benefits and were very satisfied with the activities carried out.

Abstract

This study evaluates the use of Paper Mill Sludge (PMS) waste as a partial replacement for fine aggregate in paving block production, focusing on compressive strength and economic feasibility. PMS was incorporated at 0%, 5%, 10%, 15%, and 20% of the total fine aggregate weight. Compressive strength tests followed the Indonesian National Standard (SNI 03-0691-1996), accompanied by production cost analysis. The results showed that 5% PMS achieved the highest compressive strength of 264.23 kg/cm², about 7.7% higher than the control 258.71 kg/cm², meeting the SNI quality class B (K200) standard. Meanwhile, 10% PMS reduced production costs by 6–8% while still satisfying the minimum requirement for K200 paving blocks (category B). This demonstrates a clear trade-off between mechanical performance and cost efficiency, where 5% PMS ensures maximum strength, while 10% PMS provides adequate strength with economic benefits. At lower levels, PMS fibers improved cement–aggregate bonding and reduced voids, whereas higher dosages (>10%) disrupted hydration and lowered strength. Practically, PMS utilization offers the paving block industry a sustainable and cost-effective alternative that reduces reliance on natural aggregates, supports waste valorization, and aligns with SNI standards for applications such as parking lots.

Abstract

Biodegradable plastic is a type of plastic made from renewable materials and can be produced using materials containing starch, such as in avocado seeds. However, starch-based biodegradable plastic has the disadvantage of low mechanical properties, such as tensile strength and elongation; therefore, it is necessary to add reinforcement, such as cellulose. One potential source of cellulose with a relatively high content is areca nut skin. This study aims to obtain the appropriate concentration of areca nut skin cellulose for the characteristics of biodegradable avocado seed starch plastic. A completely randomized design (CRD) with five treatments and three replications was used in the experimental procedure of the investigation. The treatments in this study were the addition of cellulose S1 (3 g), S2 (4 g), S3 (5 g), S4 (6 g), and S5 (7 g), and the measured characteristics were water absorption, water vapor transfer rate, tensile strength, elongation, and biodegradability. The data obtained were analyzed statistically using analysis of variance (ANOVA). The results showed that the addition of areca nut cellulose significantly affected the water absorption capacity, water vapor transfer rate, tensile strength, elongation, and biodegradability of biodegradable plastics. The selected biodegradable plastic was treatment S1 (3 g), which showed a water absorption capacity of 58.80%, a water vapor transfer rate of 17.03 g/m²/hour, a tensile strength of 30.73 MPa, an elongation of 9.31%, and biodegradability of 44.24%.
