Abstract

β-MnO2 was prepared and used to activate peroxymonosulphate for degradation of aqueous phenol. The sample was characterized by N2 adsorption, X-ray diffraction (XRD), scanning electron microscopy (SEM). The catalyst is highly effective in heterogeneous activation of PMS to produce sulfate radicals for phenol degradation compared with homogeneous oxidatiom. β-MnO2 could completely remove phenol in 30 min at the conditions of 25 ppm phenol, 0.4 g/L catalyst, 2 g/L PMS, and 25 oC. A pseudo first order model would fit to phenol degradation kinetics and activation energy was obtained as 38.2 kJ/mol.

Abstract

The article explores the development of the Sabang Agrotourism Area, strategically focused on essential plants such as patchouli, cloves, and nutmeg, to enhance community welfare. Sabang City, situated in the westernmost region of Indonesia, is part of the National Tourism Strategic Area with abundant natural resources. The agricultural sector, covering 19.23% of the total area, has not fully tapped into the potential of agrotourism. The absence of agrotourism in Sabang City prompted a collaborative effort between Syiah Kuala University, Atsiri Research Center, and the Sabang Free Trade Zone and Free Port Concession Agency (BPKS). The community service approach utilized community-based learning and the Quadruple Helix model, involving academics, government, business, and the community. Through Focus Group Discussions (FGD), the team addressed short-term goals by discussing agrotourism potential and long-term goals of community empowerment. The findings reveal the extensive essential crop plantations in Sabang City, particularly patchouli, and cloves. Sabang's patchouli exhibits superior quality, with the highest yield value, making it an excellent candidate for export. Cloves, besides their economic value, serve as effective antioxidants and eco-friendly pesticides. The proposed Sabang Agrotourism Area includes five zones: Reception, Agro-tourism, Thematic Park, Family Garden, and Accommodation. Each zone caters to different activities, ensuring a holistic agrotourism experience. This community service contributes valuable insights and potential breakthroughs to policymakers, agrotourism developers, farmer groups, academics, and the broader community. The comprehensive analysis of Sabang's essential natural resources underscores the region's potential as a leading agrotourism destination. The proposed Agrotourism Area serves as a strategic step towards sustainable development, augmenting community income and well-being.

Abstract

Hair issues, such as hair loss and dandruff, pose significant challenges in hair care. Patchouli oil, rich in bioactive components, has emerged as a promising candidate for addressing these concerns. The aim of this study was to investigate the hybrid functionality of fractionated patchouli oil in hair care formulations designed to promote hair growth and control dandruff caused by Malassezia globosa. Crude patchouli oil (CPO) was fractionated to enhance its efficacy, producing light fraction patchouli oil (LFPO), which was then characterized using gas chromatography-mass spectrometry (GC-MS) analysis. Hair tonic formulations containing three different LFPO concentrations (0.5%, 1.0%, and 1.5%) were developed and evaluated for stability, pH, viscosity, and antifungal activity against M. globosa. The results showed that LFPO contained 2.51% acid number, 0.70% ester number, 0.71 mg/kg iron content, and 25.88% patchoulol. The formulations exhibited stable physicochemical properties, with pH levels of 5.36–5.51 and viscosity ranging from 3.94 to 4.08 centipoise (cP), suitable for hair tonic applications. Formulation of 1.5% LFPO demonstrated the strongest antifungal activity, producing a 31.18±1.37 mm inhibition zone against M. globosa, surpassing ketoconazole (21.72±0.28 mm), suggesting potential as a natural antifungal agent. Histological analysis in rabbits revealed that 1.5% LFPO formulation reduced epidermal cell shedding, increased hair length by 41.6±0.35 mm after six weeks, and promoted dense hair follicle growth. This research provides a foundation for developing natural, effective, and stable hair care formulations. Despite these promising results, the efficacy and safety of LFPO formulations in humans remain unexplored. Therefore, a clinical human trial is necessary to assess skin tolerance, irritation risks, and long-term effects under real-world conditions.

Abstract

Limbah cair pabrik minyak kelapa sawit (PMKS) merupakan sumber pencemar potensial yang dapat memberikan dampak serius terhadap lingkungan, sehingga diperlukan penanganan terhadap limbah cair tersebut melalui peningkatan teknologi pengolahan. Salah satu metode yang dapat digunakan untuk menghilangkan zat pencemar tersebut adalah dengan proses adsorpsi. Dalam penelitian ini, adsorben yang digunakan adalah karbon aktif dalam skala nanometer. Nano karbon diaktivasi secara fisika (kalsinasi) pada suhu 700OC untuk mendapatkan volume pori yang lebih besar. Kristalinitas nano karbon aktif dianalisis menggunakan X-Ray Diffraction (XRD), sedangkan morfologi dari nano karbon aktif dianalisis dengan Scanning Electron Microscopy (SEM). Konsentrasi COD sebelum dan setelah proses adsorbsi dilakukan dengan menggunakan spektrofotometer. Penelitian ini dilakukan dengan variasi waktu kontak (0,5; 1; 2; 3; 4; dan 8) jam, massa adsorben (0,25; 0,5; 1; dan 2) gr, konsentrasi awal (47,60; 97,04; 193,84; dan 482,82) mg/l, ukuran adsorben (nano size dan mikron size), dan jenis adsorben (nano karbon aktif dan nano zeolit). Hasil penelitian menunjukkan bahwa waktu kontak, massa adsorben, jenis adsorben, dan konsentrasi awal sampel limbah mempengaruhi penyisihan COD. Waktu kontak yang optimal antara nano karbon aktif dengan COD adalah 4 jam dengan massa adsorben 2 gr. Pada jumlah atau massa adsorben yang tetap (2 gram) semakin tinggi konsentrasi awal COD di dalam sampel limbah maka persen penyisihan semakin kecil. Ukuran sampel pada skala nano memberikan hasil yang lebih baik dibandingkan ukuran sampel pada skala mikron. Hasil penyisihan COD di dalam sample PMKS untuk nano karbon aktif lebih baik dibandingkan nano zeolit. Hasil Scanning Electron Microscopy (SEM) terlihat bahwa nano karbon aktif memiliki ukuran nanometer (10-9).

Abstract

Lead (Pb) and chromium (Cr) are common groundwater contaminants at industrial installation. Zeolites are widely use as an adsorbent in heavy metal removal. Nanocrystalline zeolite Y has been synthesised from a clear solution at 1500C by using aluminum isopropoxide (Al(OiPr)3 and Ludox LS as alumina and silica source, tetramethylammonium hydroxide (TMAOH) and tetramethyl ammonium bromide (TMABr) as first and second organic template, respectively. The products were characterised by X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) to identify the structure and particle sizes. After 48 hours synthesis time, nanocrystalline zeolite Y samples were obtained with approximately average particle sizes of 268 and 119 nm for one and two organic templates, respectively. The synthesized nanocrystalline zeolite Y was applied for some metal adsorption including Pb(II) and Cr(III) and the results show that the nano crystal samples have good performance. The removal efficiency for Pb and Cr could be up to 88.97% depending on the initial concentration and temperature. The adsorption isotherms of Cr and Pb were determined from the Langmuir and Freundlich equations. The equilibrium sorption capacities (Qe) from the Langmuir equation were 270.27 mg/g and 204.08 mg/g at 300C for Pb and Cr, respectively. Kinetic adsorption analysis of nanozeolite Y shows that the pseudo second order kinetics would be better for fitting the dynamic adsorption of both Cr and Pb cations.Key words: adsorption isotherms, kinetic adsorption analysis, nanocrystalline zeolite Y
