Abstract

Synthesis of N-4-O-asetilferuloylmorpholine from ferulic acid via indirect conversion methods with acetylation, chlorination and amidation (in situ) reactions have been conducted. The acetylation was carried out using acetic anhydride reagent in pyridine solvent at room temperature for 6 hours. The chlorination was performed with thionyl chloride in benzene solvent by reflux at 75°C for 4 hours, proceeded by in situ amidation utilizing morpholine in the presence of triethylamine and pyridine using dichloromethane solvent at room temperature. The target molecule as white crystalline solids with m.p. of 91-92°C. Characterization of these compounds was committed by FTIR spectrophotometry.

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

This training was designed to introduce ecoprint techniques to members of the Women's Dharma Association of the West Papua Provincial Forestry Service, emphasizing its potential as a community-based business opportunity. The activity utilized natural materials readily available in the surrounding environment, such as butterfly pea leaves and flowers, teak leaves, and other local foliage. The training was conducted in stages, beginning with an introduction to the basic concepts of eco-printing, followed by hands-on practice using two main techniques: pounding and steaming. These techniques were applied to cloth tote bags and ceramic mugs. The results showed that participants demonstrated a higher level of proficiency in producing eco prints using the steaming technique compared to the pounding method.
