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

Social cognitive theory developed by Albert Bandura is the most influential approach to learning. This theory emphasizes that a person's behavior can be learned through observation of social models in the surrounding environment, be it teachers, parents, or peers. This theory is known as observational learning or modeling. This research aims to explore the process of observational learning in an effort to strengthen the value of the Nggahi Rawi Pahu philosophy. The research method used is descriptive qualitative.  The sample in this study were fourth semester students of the Chemistry Education Study Program. Data collection techniques were carried out by means of observation, administration of questionnaires and documentation. In this study, observational learning was carried out through 4 stages of cognition in the learning process, namely attention, retention, motor reproduction and motivation. 7 out of 10 students showed a positive response to the relevance, involvement and benefits of observational learning in an effort to strengthen the philosophy of Nggahi Rawi Pahu. This shows that through observational learning the value of the Nggahi Rawi Pahu philosophy can be improved.

Abstract

The synthesis of methyl ester nitrate (MEN) from ketapang oil (Terminalia catappa L.) have been carried out. This study aims to determine the yield and the characteristics of MEN. In this study, ketapang seed oil was obtained from the soxhlet extraction process followed by an evaporation process to separate the oil from the solvent. MEN can be produced from ketapang seed oil by esterification to convert all of FFA became ester, followed by transesterification that intended to produce ester from triglycerides and nitrationthat is reaction of esther and HNO3 to create MEN. Evaporated oil is esterified using methanol with a mole ratio of oil: methanol (1: 6), then the transesterification process using methanol with a mole ratio (1:15) gives a yield of 86%. The transesterification product was then nitrated using HNO3 and H2SO4 for 4 hours with a yield of 83%. Characterization of methyl ester using GC-MS characterization showed the presence of methyl palmitoleate (C17H32O2), methyl palmitate (C19H34O2), methyl oleate (C19H36O2), methyl 13-octadecanoic (C19H36O2), methyl stearate (C19H38O2), and methyl 18-nonadecanoic (C21H42O2). Characterization MEN using a FTIR spectrophotometer showed the presence of a C-ONO2 group at wave number 1550 cm-1, NO2 group at wave number 1365 cm-1 and a C-N group at wave number 1118 cm-1. It shows that MEN can be synthesized from ketapang seed oil.
