Abstract

One of the important competencies to be mastered by students in the 21st century is entrepreneurial competency. The development of entrepreneurship for students is related to the natural potential in Pasuruan City, namely rambutan skin in training and mentoring. With this training activity, students of SMA Negeri 2 Pasuruan learn about the role of the creative economy industry or entrepreneurship according to potential trends in business development. The implementation method is through socialization and training in making environmentally friendly liquid soap and providing some materials on solutions regarding the use of liquid soap, especially at SMAN 2 Pasuruan to be trained in making liquid soap at SMAN 2 Pasuruan. The delivery of general description material about soap, things to consider in the content of soap ingredients, soap making training, to mentoring and discussions between students and Lecturers/Students. Based on the implementation of community service activities that have been carried out, namely increasing the understanding of students and teachers of SMAN 2 Pasuruan in producing soap that has the potential to help product development ideas and improve the quality of products from rambutan skin by encouraging soap making.

Abstract

Plants produce volatiles as communication cues intra- or inter- species. Infested plants by herbivores will produce volatiles as indirect defense mechanism that attracts natural enemies of herbivores. Analysis of volatiles compounds produced by rice plant as result of infested brown plant hopper (BPH), Nilaparvata lugens Stí¢l, was done to identify compounds in the volatiles that potentially can be used as attractant for egg parasitoids of BPH, Anagrus nilaparvatae (Pang et Wang) (Hymenoptera: Mymaridae). This research was an early stage to develop formulation of parasitoid attractant. The research activities include volatiles extraction of infested rice stem by BPH eggs using acetone, n-hexane as the extraction solvents; analyses of volatile compounds with GC-MS; and bioassay of parasitoid orientation behavior to the volatiles using olfactometer methods. Extraction methods applied were maceration and continuous extraction followed by concentration. Bioassay on the parasitoid orientation behavior was done by using Y-tube olfactometer and every lot of bioassay using 30 parasitoid females with 3 replicates. The results showed that the volatile compounds of extract of infested rice stem by BPH eggs comprise of 16 components. The highest proportion of the components extracted with acetone is 2-Pentanone, 4-hydroxy-4-methyl (19,9%), while those with n-hexane is Hexanedioic acid, dioctyl ester (65%). A. nilaparvatae showed positive response to the volatiles extracted from infested rice plant by N. lugens eggs. Therefore, the volatiles can be used as an attractant for the egg A. nilaparvatae to support rice pest management.

Abstract

Microalgae are promising sources of high-value biomass and renewable energy. Chlorella vulgaris is widely recognized for its ability to grow under various trophic conditions. Co-cultivation of microalgae with bacteria has the potential to enhance biomass production, although its effectiveness depends on the cultivation system. This study compared the growth performance and volatile metabolite profiles of C. vulgaris co-cultured with an Indole-3-Acetic Acid (IAA)- and vitamin B12-producing bacterial consortium in Open Pond (OP) and Photobioreactor (PBR) systems. From June to August 2025, C. vulgaris was co-cultivated with the bacterial consortium in the OP and PBR systems for 14 days. Growth was monitored by measuring cell density at 675 nm with a UV-Vis spectrophotometer, while the volatile metabolite profiles of the biomass harvested at the early stationary phase were analyzed using Gas Chromatography-Mass Spectrometry (GC–MS). The PBR system achieved a significantly higher peak cell density (9,6 x 10⁷ cells/mL) than the OP system (4,0 x 10⁷ cells/mL). GC-MS identified 136 metabolites, with the PBR system exhibiting a higher abundance of polyunsaturated fatty acids (PUFAs). Conversely, the OP system exhibited higher levels of chavicol (1.02%) and the quorum-sensing molecule farnesol (0.53%), indicating adaptive responses to environmental stress. These findings indicate that functional bacteria benefit both cultivation systems, although the OP system requires further optimization for sustainable industrial applications.
