Abstract

Most of the waste produced in the university environment comes from the canteen. The accumulation of waste in the university environment is due to the lack of proper waste management. The sorting, collection, transportation, and recycling process has not been carried out, and even education and awareness of all university components have not been maximized. This research aims to evaluate waste management in the university environment using qualitative methods with a descriptive design. Respondents consisted of 5 informants, namely key informants (management section), primary informants (head in charge of university cleanliness, janitor, waste collection officer), and supporting informants (campus security officers). Data was collected using in-depth interviews, field observations, and document reviews, which were then validated using source and method triangulation methods. The research results stated that there were no operational standards in waste management in the university environment, unscheduled transportation schedules, and no community awareness of the need to sort waste properly. There needs to be active participation of the entire academic community and transparent policies in managing campus waste.

Abstract

The production of CPO (Crude Palm Oil) generated and utilized by the industry must consider market demand, prioritizing the quality of the final CPO product that complies with the SNI 01-2901-2021 standard. It includes free fatty acid (FFA) content, water, and impurities, with maximum limits of 5%, 0.25%, and 0.25%, respectively. Another parameter affecting CPO quality is the Deterioration of Bleachability Index (DOBI) value. This study investigates the potential use of calcium oxide (CaO) derived from seashells to improve CPO quality in the production of Red Cooking Oil (M3). The study design employed a Completely Randomized Design (CRD) with a non-factorial method. The treatment factor in this study was seashell powder heated at 600°C with varying concentrations: 0%, 1%, 2%, 3%, and 4%, as well as 1% Bleaching Earth commonly used at neutral pH (6-7 ). The treatments applied included K0 (no treatment), K1 (1% Bleaching Earth), K2 (1% Seashell Powder), K3 (2% Seashell Powder), K4 (3% Seashell Powder), and K5 (4% Seashell Powder) . The results showed that seashell powder significantly reduced free fatty acid content in K5 by 13.51%, decreased water content in K4 and K5 by 47.05%, and increased the DOBI value by 47.05%.

Abstract

Pelvic Inflammatory Disease (PID) is a serious reproductive health issue affecting women of reproductive age, with Candida albicans as a common causative agent. This infection can damage the fallopian tube mucosa, increasing the risks of infertility, ectopic pregnancy, and chronic pelvic pain. With rising antimicrobial resistance, alternative therapies are needed. Myrmecodia sp. (ant plant) is a promising herbal candidate, rich in bioactive compounds such as flavonoids, tannins, terpenoids, and saponins, known for their antimicrobial, anti-inflammatory, and antioxidant properties. This study investigates the therapeutic effects of Myrmecodia sp. extract on the fallopian tube mucosa of BALB/c mice infected with Candida albicans. Using a true experimental post-test design, 24 mice were infected for four days and treated with varying concentrations of Myrmecodia sp. extract for seven days. Data were analyzed using ANOVA for vaginal color changes and the Kruskal-Wallis test for irritation. The results revealed that Myrmecodia sp. extract significantly reduced inflammation (p < 0.001) and showed a trend toward reduced irritation (p = 0.077). In conclusion, Myrmecodia sp. is a potential herbal therapy for PID caused by Candida albicans, offering a safe and effective option to support tissue regeneration and reduce complications.

Abstract

Fruit maturing enhances maturity and quality, making fruits more attractive. This process involves physiological and biochemical changes, including increased respiration, ethylene production, texture alteration, and heat improvement. This study examines the effects of different ethylene sources: calcium carbide (CaC2), 500 mg vitamin C, and potassium permanganate (PK), on the maturing of Burahol fruit (Stelechocarpus burahol). A Completely Randomized Factiorial Design (CRFD) with five replications was employed. Treatments included E1 (control, no ethylene), E2 (0.5% CaC2 of fruit weight wrapped in cloth), E3 (500 mg vitamin C/kg fruit), and E4 (PK crystals in a sealed chamber). Data collected on day three evaluated skin color (RHS charts), texture, and mucus presence. Results showed CaC2 and PK induced optimal maturing, yielding uniformly brownish-yellow fruits (20A/Brilliant Yellow), firm texture, and no mucus. Vitamin C fails to prevent decay due to mechanical damage from forced harvesting. This study highlights CaC2 and PK as effective maturing agents, providing practical solutions for Burahol fruit post-harvest management.
