Abstract

Seberang Padang Village, South Padang District, is next to Padang City, which has approximately 200 families. This location is a crossing area between Padang-Painan, in West Sumatra. The community consists of two existing traditional markets that sell daily necessities. Besides that, there is also one elementary school, two junior high schools, and one high school. The global Covid-19 pandemic certainly affects the community's daily activities and learning activities, including children, elementary school students, middle and high school students, and the village community to fulfil their basic needs. Furthermore, the main problem of Covid-19 is not only about the effects caused by the virus on sufferers but also about its high-speed transmission. Therefore, to educate the community around the Seberang Padang village, several Chemistry Lecturers and students at the Faculty of Mathematics and Natural Sciences at Andalas University did a community engagement. They taught the community about making disinfectants and hand sanitizers without alcohol that can overcome the occurrence of Covid-19 transmission. In addition, face masks were provided for the community, and the alms of food for underprivileged residents to push down the negative impact of Covid-19.

Abstract

The Qur'an Education Park (TPQ) and Tahzhul Qur'an House (RTQ) of the Raudhatul Adzkia Jorong Dalam Koto Nagari Koto Tangah, Tilatang Kamang, and District of Agam have been launched since 2015. The students who study here are free of charge. The operational costs of education and the honorarium for educators come from donations from their community and some nomads. However, this contribution is not sufficient for operational costs. The Department of Chemistry's community service team, Andalas University, collaborated with partners to start a business to solve this problem. The business was carried out using vacant land owned by partners for catfish cultivation. Surveys, program socialization and assisting activities were carried out online using virtual media, while Partners carried out the implementation in the field. Activities carried out were pond preparation, the release of catfish seeds, feeding, sorting, maintenance, harvesting, and marketing cultivated catfish. Based on the evaluation, 5000 seedlings from the released catfish developed well. About 99% of catfish typically growth to a large and even size, while the other 1% growth relatively slowly. Harvested catfish were sold for IDR 18,000/kg for wet fish and IDR 100,000/kg for dried fish. This business has been carried out sustainably by partners, and the profits have been used to support the operational costs of TPQ and RTQ Raudhatul Adzkia.

Abstract

The Community Service Team of the Chemistry Department has worked closely with the Taman Pendidikan Qur'an (TPQ) and Rumah Tahzhul Qur'an (RTQ) Raudhatul Adzkia Jorong Dalam Koto Nagari Koto Tangah in solving problems faced by partners. The pond catfish farming business supports smooth operational costs and has been running for over a year, but these results still need to be improved for TPQ and RTQ. This activity aims to develop a catfish farming business accompanied by an aquaponic cultivation business to increase income from TPQ and RTQ. The benefit of this activity is that the partners have an Aquaponics business which is cultivating catfish and vegetable plants in the fish pond. The Community Service Team transferred knowledge to partners, especially in cultivating aquaponic plants through entrepreneurship. The activities of the Community Service Team in helping partners are a form of the Andalas University Higher Education Tri Dharma. The method applied to support the realization of this community service program was through supervision, program socialization, and implementation of activities. The result of this activity was that partners could run an aquaponics business to increase income to meet the operational costs of education and teacher salaries.

Abstract

Kaolinite is a type of clay mineral that has the potential to be used as a heterogeneous catalyst in transesterification reactions. However, natural clay still contains a mixture of minerals that occur together. Therefore, as an effort to search for cheaper catalysts to reduce the price of biodiesel production, this study carried out the separation of kaolinite from natural clay and tested its performance as a catalyst in biodiesel production from Waste Cooking Oil (WCO). Separation of the kaolinite fraction was carried out with the help of NH4Cl as a dispersing agent. The main mineral composition of clay as quartz, kaolinite, montmorillonite and hematite. After the separation process, the crystallinity of the minerals experienced an increase marked by an increase in the intensity of several kaolinite peaks, namely in the 2θ 12.24° area from 103 to 108 and at 25.00° from 95 to 125. Thermal modification caused the loss of several kaolinite peaks in the area. 2θ 12.17°; 24.94° and 62.39°. The Si/Al ratio decreased after the fractionation and calcination processes. Average particle size of h-clay decreased from 27.61 µm to 21.09 µm in K-clay. The K-clay catalyst produced the highest conversion of palmitic acid at 42%, while c-K-clay produced the highest conversion of oleic acid and stearate at 30%. In addition, the density and water content of biodiesel catalyzed by K-clay and c-k-clay meet SNI standards. This finding has the potential to be further developed as a cost-effective catalyst based on natural resources in biodiesel production.

Abstract

The CO2 mineralization pathway is considered a promising option for carbon capture usage and storage because the captured CO2 can be permanently stored, and secondly industrial waste (i.e., petrochemical refinery, lime, and cement kiln dust) can be recycled into value-added carbonate materials by controlling the crystal polymorphs and properties of mineral carbonate. This study investigated the CO2 mineralization utilized for the synthesis of precipitated calcium carbonate (PCC) via low temperatures at 30 °C and 55 °C with the addition of 50 and 75 g/L of ammonium chloride (NH4Cl). The pilot scale of PCC production was established to simultaneously produce PCC with low energy demand by reporting the feasibility of economic analysis and to develop the mineral carbonation that can transform limestones and CO2, which was captured from the petrochemical refinery process into economically valuable PCC. It is found that the aragonite phase of PCC can be generated at a room temperature of 30 °C by adjusting the CO2 flow rate. In addition, the use of NH4Cl, which transformed into ammonium carbonate ((NH4)2CO3) during the calcination process, can maintain the stable aragonite phase by varying the NH4Cl concentration.

Abstract

The Moringa plant, a tropical species, exhibits prolific growth and is abundantly present in Indonesia and other tropical regions worldwide. An extended lifespan, continuous flowering, and a high tolerance for elevated temperatures characterize it. Utilizing its components, including leaves, bark, seeds, and roots, this multifaceted plant is renowned for its therapeutic properties. The plant's antioxidants and various nutrients, including vitamins and minerals (iron, magnesium, vitamin B6, vitamin B2, vitamin C, and vitamin A), have led to studies on the plant's potential health benefits. In order to develop the local economy in Ulakan village, Padang Pariaman Regency, Moringa plants were processed by using the plant leaves to manufacture herbal tea, which can then be sold. This community service program was significant given the widespread presence and ease of cultivation of Moringa plants within the local region. The program involved the planning and selection of the activity site, the implementation of training sessions, and the assessment of the program's outcomes. The result of this community engagement initiative was the demonstrated interest of many participants in producing Moringa leaf tea.

Abstract

Lead is a toxic metal known for its harmful effects, even in minor quantities, because it does not break down naturally and can therefore pollute ecosystems. This research involved the creation of hydroxyapatite using quail egg shell through a sol-gel method, which served as a medium for capturing Pb ions in a batch process by assessing different parameters. The created material was analyzed using X-Ray Diffraction (XRD) to confirm its crystal form, SEM (Scanning Electron Microscopy) to analyze its surface, FTIR (Fourier Transform Infrared Spectroscopy), and morphology to determine the functional units that were present. Sorption tests were performed under various scenarios, encompassing different pH levels, the initial Pb ion concentration, and time of contact, with the outcome evaluated through atomic absorption spectrophotometry (AAS). The results demonstrated that the optimal conditions for Pb ion uptake were observed at a concentration of 800 mg/L with 0.1 g of absorbent as well as a contact time of 60 minutes, achieving a lead ion removal rate of 71.48%. The sorption isotherm followed the Langmuir model, while the sorption kinetics fit the pseudo-order two model, indicating a monolayer sorption mechanism on a uniform surface. These outcomes suggest hydroxyapatite derived from quail eggshells is a promising eco-friendly material for treating wastewater containing heavy metal ions.
