The increasing pollution of toxic heavy metals in the environment is an important issue worldwide. Heavy metal ions such as mercury have attracted special attention because of their high toxicity and long half-life which increase the potential to accumulate in the food chain and cause serious damage to the environment. The potential of an adsorbent durian (Durio zibethinus) seed immobilized alginate bead was carried out and used for the adsorption of Mercury in an aqueous solution. Adsorbents were characterized by FTIR, SEM, and XRF. FTIR analysis shows the functional groups of alcohol, amine, and carboxylic acid. Scanning Electron Microscopy shows that the surface morphology of durian seed powder of granules and durian seed immobilized in Ca-alginate of like as tissue eggs in an egg box shape. XRF analysis durian seed immobilized showed that Hg(II) ion adsorbed as much as 37%. The adsorption parameter of Hg(II) ion are pH at 6 with an adsorption capacity was 1.553 mg/g, contact time at 150 minutes with adsorption capacity was 2.880 mg/g, mass 0.1 g with adsorption capacity of 2.274 mg/g, and concentration 250 mg/g with adsorption capacity of 62.067 mg/g.

The abundance of waste cooking oil resulting from the cooking process has not yet been optimized for use. Apart from that, coffee is also produced in Mukai Pintu village, Kerinci Regency. The skin of these coffee beans is just waste that is thrown away. These two ingredients can be used to make aromatherapy candles which are useful for the community. In this way, the problem of waste coffee bean shells and used cooking oil can be overcome and become added value. Making aromatherapy candles from used cooking oil can be made easily by PKK women and the Mukai Pintu Kerinci village community. Coffee skin therapy aroma candles can support the economy of the community and village. Apart from that, this aromatherapy candle product made from coffee bean shells can be one of the superior products of the village and can be a souvenir from Kerinci Regency. The target for implementing this community service program is that partners are able to: 1) The community can apply and make aromatherapy candles from coffee bean shells. 2) can help the community improve the economy and can become a superior product for the village. 3) People can sell these products using digital marketing

In this study, Silver Nanoparticles (AgNPs) was synthesized using natrium citrate as a stabilizing agent and ascorbic acid as a reducing agent. The aim of this study is to investigate the optimum condition of creatinine colorimetric detection using silver nanoparticle synthesized. The reaction was carried out at temperature within an alkaline environment with a pH of 10,5. The concentration of reducing and capping agent showed a significant effect to absorption spectra via UV-Vis spectrophotometer. The produced citrate-capped AgNPs exhibited SPR absorbance within the range of 390–410 nm. The detection mechanism relies on the aggregtion of nanoparticles with analytes, resulting in a shift in Localized Surface Plasmon Resonance (LSPR) towards a longer wavelength. The experiment showed that the pH condition of the medium played an essential part in the interaction between creatinine and silver nanoparticles (AgNPs). Development of creatinine detection methods is based on the ability of tautomerization of creatinine to its anionic amino species at alkaline pH led to cross-linking with the negatively charged AgNPs through hydrogen bond networks, facilitating the aggregation mechanism. This aggregation resulted in particle resulted a color shift from yellow (with a maximum wavelength of 403nm) to dark blue (with a maximum wavelength of 670 nm) within 5 minute of reaction at pH 12. With this strategy, a linear relationship between the A670/A403 extinction ratio and creatinine concentrations was obtained in the range of 10–50μM with a coefficient of determination of 0.935.Keywords: Aggregation; Citrate; Creatinine; Silver nanoparticle; Surface plasmon

As a resource, the local cultural value of Batik Jambi with the Sungai Penuh motif is one of the driving forces in the improvement of the economy, capacity, expertise, and reputation of the region. In reality, the development of Batik Jambi with the Sungai Penuh motif is still relatively stagnant. The demand and interest in Batik Jambi with the Sungai Penuh motif have not seen significant growth from year to year. It is can be attributed to several issues, one of which is the lack of knowledge and skills regarding innovation in batik making, resulting in no distinguishing features compared to other batik motifs from the archipelago. As a solution to this problem, training and mentoring should be provided to members of the Batik community in Sungai Penuh City to innovate the Batik products they produce. The innovation introduced in this program involves the use of photochromic dyes. The basis of photochromic dyeing is the phenomenon of reversible color change induced by light in photochromic molecules, causing the molecules to exist in two different forms. These two different forms of molecules result in different colors. Practically observed, photochromic dyeing causes the applied batik products to change color when exposed to sunlight (color-changing - sun activated).

Dampak dari permasalahan banjir melanda sebagian wilayah di kota Jambi dewasa ini, banyak disebabkan oleh ulah manusia sendiri. Kurangnya kepedulian menjaga lingkungan menjadi hal utama penyebab banjir.Penyebab lain pembuangan sampah di aliran badan air, sehingga air tidak bisa mengalir dengan lancar pada akhirnya mengakibatkan luapan air.Oleh karena itu, muncullah ide pembuatan lubang resapan biopori dimana bahan utamanya adalah sampah organik. Lubang biopori berfungsi meresapkan air ke dalam tanah dan dapat digunakan untuk membuat kompos. Lubang biopori tidak membutuhkan area luas dan proses pembuatannya sangat mudah, hal ini tentu menjadi solusi yang tepat untuk wilayah dengan lahan terbuka yang sempit. Pelaksanaan kegiatan pengabdian masyarakat ini dilakukan masyarakat RT 12 (mitra) Kelurahan Kenali Besar dengan permasalahan lingkungan kekeringan sumber air yang dilanda saat musim kemarau dan kebanjiran dilingkungan sekitar. Dari permasalahan ini pemecahan masalahan dengan memperkenalkan akan pentingnya biopori sebagai lubang resapan air dan penyubur bagi tanah

The need for clean water for the citizens of Jambi City still remains a serious problem until now. Ironically, for the past five years, the difficulty of fulfilling the need for clean water in some areas of Jambi City is even more alarming. The supply of tap water to the citizenâ€™s houses is still not smooth. So as an alternative, citizens use ground water as a source of water. However, the groundwater obtained is still cloudy and smelly, and the flow of water causes the formation of the crust on the bathroom wall. This will certainly hamper the productivity and the economy of the citizens. Efforts are needed to overcome this problem so that people can get clean water. In this program, conducted a counseling or socialization on the way of water treatment from well water. This community service program aims to share knowledge about how to conduct water purification process to the community so that citizens can consume clean water. In this program, performed demonstration of a simple water purifier using Rapid Sand Filter method in the presence of zeolite and activated carbon that will maximize the water purification process.
