Abstract

Kotabatu Village, located in Bogor District, is home to several Fish Cultivator Groups (Pokdakan), one of which is Pokdakan Baraya, focused on cultivating catfish. Based on a focus group discussion conducted by the Pakuan University Implementation Team, Pokdakan Baraya faces challenges related to low income, high production costs, and the risks involved in traditional fish farming practices. In response, the team proposed the introduction of the Biofloc system for fish cultivation. The service methods included a comprehensive survey to assess the conditions and needs of the target community, followed by focus group discussions (FGD). The next phase involved outreach by the Pakuan University service team, employing knowledge-sharing methods, case studies, and training on the biofloc technology. To evaluate the impact, regular monitoring and evaluation processes were implemented, which included counseling, pond construction, seed distribution, nursery establishment, and intensive catfish rearing using the biofloc system. As a result of the biofloc system’s adoption, pond productivity increased by 1.8%, and the harvest time was reduced by 15 days. Additionally, the knowledge of Pokdakan Baraya members regarding fish cultivation technology grew by 60%, and their income saw an 81% increase from the sale of the catfish. The successful implementation of this system demonstrates significant improvements in the efficiency, productivity, and economic stability of the community.

Abstract

Program Penguatan Kapasitas Kemahasiswaan team (PPK Ormawa) of Himpunan Mahasiswa Kimia (HIMASKA) of the Faculty of Mathematics and Science, Pakuan University has implemented a water resource conservation program to overcome floods and droughts that occur every year in Kalong Liud Village, Nanggung District, Bogor Regency, West Java Province. Water resource conservation with green ampel bamboo (Bambusa vulgaris Schrad. ex. J.C) uses a combination of vegetative and agronomic methods with the aim of maximizing erosion control and surface flow of the Cikaniki River. This program began with a survey of village locations, socialization and education to maximize the sustainability of the implementation of the program by holding pre-tests and post-tests for community groups and residents around the Cikaniki River. After that, green ampel bamboo was planted on the cleared and dug land 50 cm deep with a hole diameter of 15 cm. The growth of green ampel bamboo is monitored and evaluated once a week to find out how to optimize its growth. As a result, young leaves grow from bamboo books after 3 (three) weeks of planting and maintenance. In addition, the provision of education and scientific approaches can increase public understanding and awareness of climate change that can cause flood disasters.

Abstract

Sao Pedro Petro cassava tubers (Manihot esculenta Ctro) are one of the cassava varieties, generally cultivated in tropical and subtropical areas. This plant has the potential to contain antimicrobial bioactive compounds. This research aimed to demonstrate the antibacterial activity of each fraction and subsequently identify the specific active fraction for in-depth analysis of its bioactive compounds. The evaluation of antimicrobial activity and the identification of bioactive compounds were conducted using the well-diffusion method and UPLC-QTOF MS (Ultra Performance Liquid Chromatography-Quadrupole Time of Flight Mass Spectrometry). Results indicated that the ethanol, n-hexane, and n-butanol fractions exhibited no inhibitory effects on the tested microorganisms. In contrast, the ethyl acetate fraction displayed the highest level of antimicrobial activity (Staphylococcus aureus ATCC 6538, Pseudomonas aeruginosa ATCC 27853, and Candida albicans ATCC 1023). Further analysis of the ethyl acetate fraction revealed key bioactive compounds, including Coixol (phenol-group), Trigonelline and 2,6-Dimethyl quinoline (alkaloid-group), and Chebuloside-II (terpenoid-group). In summary, this pioneering research represents the first-ever exploration of the antimicrobial potential of cassava tubers, specifically focusing on the Sao Pedro Petro variety. The study not only underscores the antimicrobial properties of Manihot esculenta tubers but also identifies specific bioactive compounds within them, providing valuable insights into their potential therapeutic applications

Abstract

The object of this research was to determine the antioxidant potential and identify active compounds in the peel extracts of red dragon fruit (Hylocereus costaricensis) and white dragon fruit (Hylocereus undatus). Phytochemical tests were conducted to identify flavonoids, alkaloids, tannins, coumarins, and saponins. The antioxidant activity was assessed using the DPPH assay, while vitamin C content was quantified using UV-Vis spectrophotometry, and bioactive antioxidant compounds were identified through LC-MS/MS spectrophotometry. The results demonstrated that phytochemical screening revealed the presence of flavonoids and alkaloids in both extracts. Antioxidant activity assays indicated that the red dragon fruit peel extract exhibited an IC50 of 32.7 ppm (very active), while the white dragon fruit peel extract had an IC50 of 50.2 ppm (active), with the vitamin C control showing an IC50 of 11.90 ppm. The red dragon fruit peel extract had the highest vitamin C content (1.45%) compared to the white dragon fruit peel (1.04%). LC-MS/MS analysis identified several organic compounds, including the flavonoid isoliquiritigenin and alkaloid compounds such as aporphine, melosmine, 3-carbamoyl-1-(2-deoxy-beta-D-erythro-pentofuranosyl)-4,5-dimethylpyridinium, and alkaloid group (6-Amino-5-{[2(diethylamino) ethyl]amino}-1-propyl -2,4(1H,3H)-pyrimidinedione). These findings suggest that both red and white dragon fruit peel extracts possess significant antioxidant potential, with red dragon fruit peel demonstrating superior activity. This study can be used for further research on food technology in producing food products that are rich in nutrients.

Abstract

The main objective of this study is build the new normal bogor batik village which is integrated with collaborative learning, so as to create the academic triangle ecosystem. The academic triangle is cyclical in nature, which continues as an ecosystem of education, research and entrepreneurship (not only being an entrepreneur but an entrepreneurial spirit that never gives up in the face of all obstacles). This cycle involves lecturers and students who at the same time have a positive impact on improving the social economy and strengthening local culture. Hopefully, in the end, the ecosystem can become a laboratory for strengthening the academic triangle

Abstract

The batik industry produces waste containing dyes from the process of dyeing batik cloth. Remazol brilliant blue (RBB) is a reactive dyestuff, used in the fabric dyeing process. RBB levels in waste can be reduced by means of adsorption using activated banana stem charcoal. This study aims to make, characterize and test the quality of activated charcoal from banana stems, determine the optimum conditions, adsorption capacity and RBB adsorption isotherm model and its application in absorbing RBB in Bogor batik industrial waste. The results showed that the intensity of the functional groups in the FTIR spectrum of activated charcoal was greater, with the surface morphology in SEM indicating that the pores of the activated charcoal were more open than the charcoal before activation. The quality of activated banana stem charcoal meets the requirements of SNI No.06-3730-1995 for 0.63% moisture content, 13.30% volatile matter content, 80.67% carbon content and 88.65 mg/g methylene blue absorption capacity. Optimum adsorption conditions occurred at pH 8, contact time 120 minutes, and 1 gram weight of activated charcoal for 50 mL of batik waste. The adsorption process suitable for the adsorption of remazol brilliant blue is the Freundlich isotherm with a maximum adsorption capacity of 10.7411 mg/g and an adsorption efficiency of 96.29%. Characterization of batik waste after adsorption meets the requirements of PermenLHK No.16 of 2019 for parameters pH 8.37, color test 194.3 PtCo and Total Suspended Solid (TSS) 38.6 mg/L.
