Abstract

Cancer is a group of deadly diseases that attack human organs with an increasing number of cases and an increasing number of deaths from year to year. Free radicals as unstable molecules are one of the triggers for the emergence of cancer. Katang-katang or I. pes-caprae L. is a plant that could be found on almost all tropical coasts. So it has the potential to be developed as herbal medicine. This study used Flowers of I. pes-caprae L. as the research sample. This study aimed to identify the anticancer and antioxidant potential of the flower extract of I. pes-caprae L extracted with water as a solvent. This research included the phytochemical test of secondary metabolites, identification of anticancer potential based on the toxicity test using the Brine Shrimp Lethality Test (BSLT), and the antioxidant activity test using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. The results showed that the flower extract of I. pes-caprae L. from water solvent contained active compounds including alkaloids, flavonoids, tannins, saponins, and terpenoids. The extract also has the potential as an anticancer with an LC50 value of 170.8441 ppm and strong antioxidant activity with an IC50 value of 71.7895 ppm.

Abstract

Chitosan-PVA composite with the addition of binahong extract is a bioplastic that is being developed aims to make eco-friendly product and contain antibacterial agents. This bioplastic is useful as packaging to maintain the freshness quality of food. The purpose of this research is to study and develop smart packaging with the addition of binahong leaf extract as an antibacterial agent. The manufacture of plastic in this study was carried out by varying the addition of binahong leaf extract ranging from 60-100%. The characteristics of the chitosan-PVA plastic were tested through FTIR, water uptake, and antibacterial tests. Chitosan-PVA plastic with the addition of 100% concentration of binahong extract had a good bacterial inhibition of 12 mm. The resulting chitosan-PVA plastic with binahong extract showed the presence of chemical bonds between the chitosan, PVA and flavonoid groups. The bioplastics produced have quite a large water uptake compared to non-biodegradable commercial packaging, reaching 491.52% with the addition of 90% binahong extract with the best antibacterial capabilities in the packaging with the addition of 100% binahong extract.

Abstract

In this study, shrinkage level, moisture content, and drying rate of Eucheuma cottonii seaweed were compared using various drying times and methods. Both sun and wind drying were employed, with drying times ranging from 0 to 240; 480; 720; and 960 minutes for each method. In Pajukukang Subdistrict, Bantaeng Regency, Eucheuma cottonii seaweed was harvested and dried using a variety of drying methods. The findings indicated that the Pajukukang Subdistrict was extremely hot, with the greatest temperatures and relative humidity readings of 52.4 oC and 47% RH (sun drying) and 32.6 oC and 55% RH (wind drying). The seaweed also changed after drying, going from a fresh brown color to a deeper brown color with an extremely dry physical shape (sun drying) and dry with white spots all over its surface (wind drying). Additionally, when drying time increases, shrinkage level increases. On a wet and dry basis, however, the converse occurred, where the two types of moisture content dropped as the drying time increased. When the drying time increases for both drying processes, a phenomena known as a falling rate period happens for the relationship between the drying rate and the moisture content on a dry basis.

Abstract

Purpose: The local food processing business is essential to the Indonesian economy. Lumpangan Village in Bantaeng Regency, South Sulawesi, has great potential due to the Small and Medium Enterprises (SME) product "SEHATI," which manufactures Marning Corn. However, the need on sunshine for drying limits production, reducing output during the rainy season. To address this issue, the Akademi Komunitas Industri Manufaktur Bantaeng community service programme strives to improve corn product quality through the use of mechanical dryers and the education of workers on Good Manufacturing Practices (GMP). Methodology: This program's methodology comprises collaborating with village officials, observing SMEs, developing solutions, implementing the community service programme, and assessing the program's success. Results: Observations show that mechanical dryers are successful in resolving drying problems, and GMP education enhances product quality. Conclusions: The service program was successful in raising the marning corn production by UMKM "SEHATI" and establishing the program as a long-term initiative. In addition, the program received the full support of village officials by the successful in overcoming production constraints during the rainy season through the purchase of corn dryers and Good Manufacturing Practice (GMP) education. Limitations: Prior to deployment, the primary drawback was a reliance on dry weather conditions. Contributions: This programme makes a substantial contribution, with the expectation that its long-term success will help to create other SMEs in Lumpangan Village and increase the quality of Marning corn products through better drying technology and worker education.

Abstract

Environmental conscious technology, or green technology, has become a significant focus for countries worldwide. The development of environmentally friendly materials is a top priority, and it is a major concern for researchers who continue to conduct studies to support the advancement of green technology. Research on the Hibiscus tiliaceus tree bark fiber (known as 'waru' in Indonesian) has become relevant in this context. These fibers have undergone treatment with NaOH and turmeric and are utilized as reinforcements in composites or combined with epoxy resin. This study aims to empirically assess their mechanical properties and is expected to provide valuable insights into the application of green and environmentally friendly technology. The objective of this research is to identify the effects of various treatments. These treatments include immersing the fibers in a NaOH 5% solution for 2 hours, heating the turmeric in a 20% solution to a temperature of 70-80°C, followed by a 2-hour incubation, as well as immersing the fibers in a NaOH 5% solution for 2 hours, followed by heating the turmeric in a 20% solution to 70-80°C for another 2-hour period, with respect to the bending strength of the waru tree bark fiber composites. Impact testing is conducted using ASTM 256, and the results show that the best impact energy, with the highest fracture energy, is achieved with the specimen that underwent the NaOH 5% solution treatment for 2 hours, reaching 2.142 Joules. The best impact strength was observed in specimens without any treatment, with a value of 1.529 Joule/mm².
