Abstract

Zeolite, as an adsorbent, can be improved by a chemical activation process. In this study, zeolite was activated using the acid activation method by soaking natural zeolite with HCl and HF, and the activated zeolite was then used to adsorb Fe metal. Zeolite was characterized using SEM and XRD, and the adsorption capacity of the zeolite was analyzed using AAS. The results of SEM analysis show that zeolite after activation has a more significant number of pores than zeolite before activation. The results of XRD analysis show that zeolite that has been activated has a higher content of quartz (SiO2) and clinoptilolite than zeolite that has not been activated. The results of the zeolite adsorption capacity and efficiency test on Fe metal showed that the most excellent adsorption capacity was when the contact time was 60 minutes, with adsorption capacity and adsorption efficiency values of 3.2403 mg/g and 97.21%.

Abstract

The potential uses of ecologically benign nickel nanoparticle manufacturing in various sectors, such as biomedicine, energy storage, and catalysis, have garnered much interest. This paper covers green approaches to nickel nanoparticle manufacturing, which integrate natural substances as stabilizing and reducing agents with eco-friendly processes. Phytochemicals derived from bacteria, microorganisms, and plant leaf extracts can convert nickel ions (Ni2+) into nickel nanoparticles. Room temperature is used for the synthesis procedure, and neither dangerous compounds nor unusual reaction conditions are used. Using a variety of analytical methods, the resultant nickel nanoparticles were characterized. We also investigate the possibility of using the generated nickel nanoparticles as a cytotoxic, photocatalytic, antioxidant, and antibacterial agents. The antimicrobial activity of nickel nanoparticles demonstrates their potent antibacterial properties, while their antioxidant activity demonstrates their capacity to combat free radicals effectively. Furthermore, nickel nanoparticles' cytotoxic activity demonstrates their capacity to kill cancer cells, and their photocatalytic activity demonstrates their efficiency in breaking down organic contaminants. This review highlights the value of ecologically benign synthetic methods and creates new avenues for developing nickel nanoparticle applications in health and the environment.

Abstract

Slag waste from the metal refining industry, if left to accumulate for a long time, can become a source of environmental pollution due to the content of heavy metals that can dissolve and spread to the surrounding environment. However, slag can also be an alternative source for obtaining valuable metals. Aim: This study aims to examine the ability of diethylaminedithiocarbamate ligands to recover nickel metal from slag waste through the mechanism of complex compound formation. Methodology and results: The extraction process was carried out at the optimal pH for each ligand to maximize the selectivity and efficiency of metal recovery. Characterization of the complex compounds from the reaction was carried out using various analytical techniques, including Fourier Transform Infrared Spectroscopy (FTIR), UV-visible spectroscopy (UV-Vis), X-Ray Diffraction (XRD), Scanning Electron Microscopy with Energy Dispersive X-ray Spectroscopy (SEM-EDS), and melting point tests to determine the thermal stability of the compound. The study results indicate that diethylaminedithiocarbamate ligands can selectively form complex compounds with nickel metal in slag and are effective in recovering metals from slag waste with a recovery value of 94.88%. Conclusion, significance, and impact study: The results of this study indicate that using diethylaminedithiocarbamate ligands can be an environmentally friendly approach to using slag waste as a secondary source of metals.

Abstract

Bawang merah varietas Lembah Palu (Alium Wakegi Araki) merupakan salah satu jenis bawang merah lokal yang di budidayakan secara tradisional oleh petani terutama di Lembah Palu, Sulawesi Tengah. Bawang ini merupakan salah satu komoditi sayuran hortikultura yang biasa digunakan sebagai kebutuhan pokok, tetapi dibutuhkan oleh konsumen rumah tangga sebagai penyedap bumbu masakan, bahan baku industri makanan. Di Propinsi Sulawesi Tengah, khususnya di Lembah Palu terdapat komoditas bawang merah unggul lokal daerah yang sudah cukup dikenal sebagai sumber bahan baku bawang goreng dan dikenal sangat khas dibandingkan dengan bawang lain yang ada di tanah air. Jenis bawang merah lokal Palu saat ini banyak diusahakan di Lembah Palu tetapi produksi yang dihasilkan masih rendah. Penelitian ini bertujuan untuk mengetahui pengaruh waktu aplikasi pupuk organik terhadap dinamika tumbuh tanaman bawang merah varietas lembah Palu. Penelitian akan dilaksanakan di kebun akademik Fakultas Pertanian, Universitas Tadulako, Palu Sulawesi Tengah. Penelitian ini akan berlangsung selama 2 bulan Agustus sampai September 2023. Penelitian inimenggunakan Rancangan Acak Kelompok (RAK) satu faktor, dengan perlakuan yang dicobakan ialah waktu aplikasi pupuk kandang sapi yang terdiri dari empat taraf yaitu W1 = sehari setelah tanam, W2 = 5 hari setelah tanam, W3 = 10 hari setelah tanam, dan W4 = 15 hari setelah tanam. Penelitian menunjukan bahwa waktu aplikasi pupuk organik pada parameter Barat kering pertanaman, Luas daun pertanaman, Laju asimilasi bersih, Laju tumbuh relatif dan nisbah luas daun. Tabel rata-rata Anova tidak berpengaruh nyata terhadap waktu pemupukan pada tanaman bawang merah diduga akibat kurangnya suplai unsur hara yang dibutuhkan untuk pertumbuhan dan perkembangan tanaman terutama untuk pembentukan umbi. Tanah juga sangat berpengaruh pada tanaman oleh karena itu kurangnya unsur hara yang dibutuhkan untuk pertumbuhan tanaman bawang merah terutama untuk pembentukan umbi.

Abstract

The production process with the green synthesis method is a method that is being developed in the production process for daily household needs. One of the green synthesis methods that has been developed is using waste products such as waste cooking oil (WCO) as a raw material in the soap production process. In the process of making soap, saponification reactions occur between triglycerides and fats and oils that occur in alkaline solutions. The materials used are a mixture of WCO, distilled water, and sodium hydroxide. The WCO used in this training is purified WCO with the addition of natural zeolite. Acid-activated natural zeolite, to increase its catalytic ability, is used as an adsorbent to adsorb impurities contained in WCO. The training consists of three stages: providing material about the dangers and negative effects that can be caused by using used cooking oil in everyday life for both the environment and health, the WCO cleaning process, and the utilization of purified WCO into an efficient product in the form of laundry soap. The results of the activities carried out can be seen from the discussion activities carried out after the activity took place with the partner community, which show an increase in community knowledge about how to treat waste and the potential for improving the economic situation of the community through knowledge of the soap-making process.

Abstract

This community service program titled "Socialization and Training on the Utilization of Solar Energy as an Environmentally Friendly Electricity Source in Karang Taruna, Gambir District" aimed to address the critical issues faced by the community due to their heavy reliance on unstable and costly fossil energy from PLN (the state-owned electricity company). The program also targeted the low understanding and practical skills related to solar energy and the underutilization of solar energy potential in urban settings. The implementation comprised two core components: socialization of solar energy and climate change impacts, and hands-on training on mini solar panel systems. Using interactive lectures, demonstrations, direct practices, and discussions, the program was conducted on March 16, 2025, involving 31 participants mainly from Karang Taruna members. A significant improvement in participants’ comprehension was observed, with average pre-test scores rising from 45 to 82, indicating an 82.22% increase. Furthermore, participant satisfaction reached 90.32%, alongside a 70.96% enhancement in practical ability to operate mini solar panel setups. Key outputs included teaching materials, posters, and scientific articles, collectively contributing toward enhanced community energy independence, reduced electricity costs, and promotion of clean energy adoption in urban areas.
