Abstract

Contamination by heavy metals, especially lead (Pb) and cadmium (Cd), presents considerable environmental and public health hazards. This study examined the efficacy of a composite adsorbent composed of eggshell powder (ESP) and Palm Oil Fuel Ash (POFA) in eliminating Pb and Cd from polluted river water. BET analysis indicated that the ESP-POFA composite demonstrated enhanced surface area and pore volume post-activation, achieving a peak surface area of 38.79 m²/g at a 1:0.75 ESP:POFA ratio. The peak adsorption efficiency for Pb was 87.16%, achieved at a 1:0.25 ESP: POFA ratio after 180 minutes of agitation, whereas Cd adsorption peaked at 94.17% at a 1:0.75 ratio with the same agitation time. The adsorption capacity fluctuated according to the ESP: POFA ratio, with Pb attaining 0.00038 mg/g at the 1:0.25 ratio and Cd achieving 0.00099 mg/g at the 1:0.75 ratio. The findings demonstrate that the ESP-POFA composite is a sustainable and economical solution for water treatment and is exceptionally proficient in removing cadmium from river water. These findings endorse the composite's potential for extensive water treatment applications; nevertheless, additional modification is necessary to enhance Pb adsorption capability.

Abstract

Each family member must have the skills to support each other in improving the family's welfare. Husbands and fathers, as heads of the family, must be able to manage all family activities. As the family's financial manager, the mother has the authority to manage all family income well so that it can be used to meet the family's needs. Mothers and children can also contribute to finding sources of revenue for the family. This community service activity (PkM) is carried out by improving the skills of mothers and young women to manage family finances and strengthen business skills as an alternative source of family income. The business skills provided are sewing traditional community clothing at the activity partner's location. All participants were very enthusiastic about participating in the training activities. This was evident from the discussion and the many questions asked by group members. Members and prospective group members hope that training activities to improve skills for women can continue to be carried out in the future.

Abstract

Coffee is one of the strategic plantation commodities that has high economic value and an important role in the national economy. Among the various types of coffee cultivated in Indonesia, Coffea liberica has great development potential, especially in areas such as Jambi Province. However, conventional propagation of Liberica coffee plants through seeds orcuttings still faces obstacles, such as low success rates and slow growth rates. Therefore, tissue culture techniques are an alternative solution to produce Liberika coffee seedlings in bulk, quickly, and uniformly. This study aims to optimize the effect of growth regulator (ZPT) concentration interaction of auxin (2,4-D) and cytokinin (BAP) on liberica coffee callusformation in vitro. Experiments were conducted at the Plant Biotechnology Laboratory, Jambi University, using a factorial completely randomized design (CRD) with two factors. The first factor is the concentration of 2,4-D which consists of two levels, namely 1 ppm (d1) and 2 ppm (d2). The second factor is the concentration of BAP which consists of five levels, namely 1 ppm (b1), 2 ppm (b2), 3 ppm (b3), 4 ppm (b4), and 5 ppm (b5). Parameters observed included color, structure, size, and callus weight after 12 weeks of culture. The results showed that the interaction between 2,4-D and BAP significantly affected all observation parameters. Callus with the highest size (2.66 cm) and weight (2.90 g) were obtained in the combination of 1 ppm 2,4-D + 4 ppm BAP and 2 ppm 2,4-D + 1 ppm BAP respectively. The callus was yellowishwhite to green and had a crumbly or compact structure, depending on the ZPT combination. In conclusion, a balanced combination of ZPT concentrations greatly determines the success of Liberika coffee callus proliferation, and the results of this study provide an essential basis for the development of efficient coffee tissue culture.
