Qur’an-Memorizing Boarding School Kaffah Al-Mundzirin Palembang is facing two problems: threat of scabies outbreak and poorly managed waste of used cooking oils. Production of soap from used cooking oil can be a two-pronged solution for these problems. Public Service Team from Faculty of Mathematics and Natural Sciences, Universitas Sriwijaya have carried out health counseling and training of soapmaking to 36 students, school administrators, and guests. Health counseling explains about the symptoms, spread, mitigation, and prevention of scabies, while soapmaking training explains about the cold process saponification method by demonstration. This activity has successfully implanted knowledge about scabies and method of soapmaking from used cooking oil within students and school administrators. Moving forward, we suggest that this activity to be accompanied with training of marketing methods and strategies so that the soap that were made can be turned into a sellable product to help with the school’s economy.

In the process of cooking, chemical reactions that happen to the vegetable oil render it unfit for consumption after multiple reusage, thus turning the oil into waste. Due to the abundance of such waste, it is important to have an easy way to turn waste cooking oil into another useful commodity. Production of soap is one of such method that could be widely applied by the public due to the easiness of its procedures and no involvement of hazardous chemical, in contrast to the production of biodiesel or biofuel which sometimes demands the use of unsafe materials or conditions. The objective of this publication is to provide information about the differences between unused and used cooking oil, to lay out the methods of soapmaking, to review the academic reports of soapmaking from waste cooking oil, and to summarize the challenges that are still unsolved in this topic.

In order to improve the adsorption performance of CaO prepared from duck egg shells, a 1:1 composite of CaO/Fe3O4 were synthesized using a coprecipitation method. This composite was then used to adsorb Congo red and Procion red MX-5b dyes from an aqueous solution. The adsorption process was studied by investigating the effects of contact time, temperature, and initial concentration of dye. It was found that the optimum conditions for Congo red adsorption are 50 minutes of contact, 50 °C, and 225 mg/L of dye, while for Procion red MX-5b the conditions are 50 minutes of contact, 60 °C, and 250 mg/L of dye. The behavior of both adsorbents at equilibria follows a pseudo-second-order kinetic model and Langmuir isotherm, with the adsorption capacity at optimum condition for Congo red and Procion red MX-5b 46.95 mg/g and 47.39 mg/g, respectively. Thermodynamics studies showed that the adsorption process of Congo red was endothermic, while Procion red MX-5b was exothermic, yet both were found to happen spontaneously.

Graphene oxide and reduced graphene oxide have been widely studied as a biomass-sourced alternative to graphene for their various capabilities, e.g. as adsorbent. This publication reports the preparation of graphite (g), graphene oxide (GO), and reduced graphene oxide (rGO) from coconut shell (1) and sugarcane bagasse (2) using matoa leaves extract as reducing agent, characterized by XRD, FT-IR, and Raman spectroscopy. The X-ray diffractogram showed 2θ peaks between 22.8°–23.8° for g1, GO1, and rGO1, and between 23.6°–25.8° for g2, GO2, and rGO2. FT-IR spectra of both sets of GO and rGO showed common peaks of O–H (~3400 cm–1), C–H (~2900 cm–1), and C–OH (~1600 cm–1), while also some noticeable differences between the sets. Raman spectra of both rGO showed D peak (~1400 cm–1), G peak (~1700 cm–1), and weak 2D peaks (2700–3300 cm–1) with ID/IG of 0.93 and 0.91 for rGO1 and rGO2, respectively. The obtained g, GO, and rGO were used as adsorbent for methylene blue dye. The adsorption study involved variation in dye concentration, contact time, and amount of adsorbent. It was found that rGO performs best as adsorbent compared to GO and g, with maximum adsorption capacity of 22.308 μg/mg (rGO1) and 47.533 μg/mg (rGO2). Adsorbents prepared from sugarcane bagasse were found to perform better due to its easiness of carbonization compared to coconut shell.

Releasing polluted water directly into the environment causes serious problems because it contains harmful substances that can damage aquatic life and human health. To reduce these risks, it is important to treat and clean wastewater effectively. Microalgae have shown promise as a natural and sustainable way to treat wastewater. The microalgae help to remove pollutants and can also recover useful resources and energy from the water. The study used a systematic review methodology to identify and evaluate the role of microalgae wastewater treatment. The method was used since it provides a structures and transparent framework for selection, assessment and synthesize of evidence from relevant literature. This review highlights the benefits of using microalgae for wastewater treatment, as well as the challenges involved. Ongoing research focuses on improving these methods, including combining microalgae with bacteria to make the process more efficient and scalable. Despite some difficulties like contamination risks and regulatory issues, future advances especially in genetic engineering and hybrid systems are expected to improve microalgae-based wastewater treatment and make it a key tool for protecting the environment, while multidisciplinary collaboration combining molecular biology research, environmental engineering, public policy, and utilization of this technology at the industrial and societal levels that should be under consideration.
