Abstract

The red fruit (Pandanus conoideus) is an endemic plant from Papua, known for its distinctive color and shape. This fruit is recognized for its bioactive properties, such as antioxidant, anti-inflammatory, and antihyperglycemic effects. Its high pigment content is believed to have potential as a sensitizer in DSSC applications. However, research on this topic remains underexplored. Therefore, the aim of this preliminary study is to investigate the potential of red fruit pigments for DSSC. The characterization of red fruit pigments was conducted through phytochemical screening, FTIR and UV-Vis spectral analysis, as well as literature reviews. Pigment extraction was carried out using maceration without involving drying or grinding processes. Phytochemical screening results revealed that the macerate contains flavonoids, alkaloids, phenolics and terpenoids, compounds commonly used as natural pigments in DSSCs. FTIR analysis showed the presence of functional groups such as carboxyl (-COOH), carbonyl (C=O), and hydroxyl (-OH), which can act as effective anchoring groups when interacting with nanosemiconductor surfaces. Meanwhile, UV-Vis analysis showed absorption peaks in the UV region (wavelength 204–399 nm) and the visible region (wavelength 400–550 nm). Based on literature studies and research findings, it can be concluded that the pigments in red fruit have potential applications as DSSC sensitizers.

Abstract

Renewable energy (RE) is a solution to the threat of the upcoming energy crisis. The increasingly massive energy transition is expected to significantly reduce the use of fossil fuels. Microalgae are one of the potential sources of RE for bioenergy (biodiesel) production due to their lipid content. This research was conducted to determine the percentage of lipid components; free fatty acids (FFA), monoglycerides (MAG), diglycerides (DAG), and triglycerides (TAG) in Chaetoceros calcitrans microalgae and to compare lipid yields using two extraction methods: Bligh-Dyer (wet samples) and Soxhlet extraction (dry samples).The results for C. calcitrans extracted using the Bligh-Dyer method showed that the percentage of lipid components (FFA, MAG, DAG, and TAG) ranged from 5.44% to 17.10%, with a total of 47.92%, and the lipid yield from 6 g of wet sample was 5.07%.Meanwhile, for the C. calcitrans extract using Soxhlet method, it was found that the percentage of lipid components (FFA, MAG, DAG and TAG) ranged from 6.79 to 18.01% with a total of 63.08% and the lipid yield from 20 g of dry samples was 0. 44%.

Abstract

Arenga sap is the primary raw material utilized by the community of Giri Madia Village, predominantly processed into conventional palm sugar blocks. However, the quality of the produced sugar remains low due to traditional processing methods, resulting in a relatively short shelf life and limited market value. Additionally, the lack of knowledge regarding product diversification has prevented the community from optimizing the potential of derivative products such as palm sugar granules (gula semut). Through the KKN-T program, an initial observation was conducted to identify issues found in the village’s production process, followed by a technical trial of granulated palm sugar processing using a crystallization machine, a drying oven, and a grinding machine. The results demonstrated that the application of appropriate technology significantly improves product quality, particularly in terms of texture, moisture content, and product stability. A socialization session was conducted to inform the community that palm sugar blocks can be converted into granulated palm sugar through reheating, crystallization, and drying processes. The introduction of this technology enhanced the community’s understanding of product diversification and broader market opportunities. Positive responses from participants indicated that the activity effectively addressed previously encountered issues and increased motivation among artisans to develop higher-value palm sugar products. Thus, the socialization and demonstration activities serve as an initial step toward enabling the Giri Madia community to optimize palm-based products as a competitive and sustainable local commodity.

Abstract

Giri Madia Village, Lingsar District, West Lombok Regency, has the potential for non-timber forest products in the form of sugar palm, which is managed by the Giri Madia Forest Farmers Group (KTH) under the Community Forestry (HKm) scheme. Although processed sugar palm products such as palm sugar, palm sugar, liquid palm sugar, and other derivative products have high economic value, their development still faces limitations in the marketing aspect. This community service activity aims to strengthen market access for sugar palm products through event-based marketing assistance. The implementation method is carried out in stages, including preparation, implementation, and evaluation stages. Marketing assistance is carried out through participation in several public events, namely Car Free Day (CFD) on Jalan Udayana, the opening bazaar of the 126th TNI Manunggal Membangun Desa (TMMD) at Dasan Griya, and Sunday Morning activities at the West Lombok Regent's office area. The results of the activities show that event-based marketing is able to increase product visibility, expand consumer reach, and increase the capacity and confidence of KTH members in marketing sugar palm products. In addition, the diversification of processed sugar palm products also increases the product's appeal in the market. This activity is expected to become a sustainable marketing strategy to support the economic empowerment of the Giri Madia Village community based on local potential.
