Abstract

The purpose of this study was to determine the adsorption kinetic model of Cd(II) from aqueous solution using Surfactant Modified Activated Carbon-Sodium Lauryl Sulphate (SMAC-SLS). This study began by varying pH, contact time, and adsorbate concentration. The concentration of Cd(II) was measured using a spectrophotometric method. The results of the analysis showed that the optimum pH occurred at pH 5 with an adsorption percentage of 84.58±1.44% and the optimum contact time at 100 minutes with an adsorption percentage of 88.75±1.5%. Furthermore, in the variation of adsorbate concentration, the adsorption percentage decreased with increasing adsorbate concentration. The adsorption kinetics followed a pseudo second order with an R2 value of 0.9945 with an adsorption capacity of 8.89 mg/g. Thus, the use of SMAC-SLS as a future adsorbent for Cd(II) is highly recommended.

Abstract

Penyusunan referensi dalam artikel ilmiah sangat diperlukan dalam rangka meningkatkan kualitas sumber dari suatu artikel ilmiah yang dibuat oleh mahasiswa. Kegiatan ini masih kurang diperhatikan dan menjadi fokus dari mahasiswa karena dianggap tidak penting dalam kerangka artikel ilmiah. Hal ini terlihat dari masih terbatasnya wawasan dan pengetahuan mahasiswa dalam mencari dan menyusun sumber informasi dengan baik pada artikel ilmiah. Dengan demikian diperlukan kegiatan pelatihan penggunaan aplikasi mendeley kepada mahasiswa. Pelatihan ini bertujuan untuk memberikan wawasan dan pengetahuan mengenai penyusunan referensi artikel ilmiah dengan menggunakan aplikasi Mendeley. Mitra kegiatan ini adalah Jurusan Kimia FMIPA UNM yang terletak di Kecamatan Tamalate, Kota Makassar, Provinsi Sulawesi Selatan. Adapun materi yang disampaikan mengenai tata cara membuat daftar pustaka menggunakan aplikasi Mendeley. Kegiatan pengabdian ini dilaksanakan melalui tiga tahapan.

Abstract

Bioinorganic science and the utilization of metal ions in the synthesis and design of new materials have received considerable attention in relation to their use as new biomaterials. One of the important roles of metal ions is to control the characteristics of the resulting biomaterials, namely their biological and chemical properties. To date, main group metal ions and transition metals have been used in the fabrication process of silicate and phosphate-based ceramics. Metal ions are used to modify their chemical composition and structure to overcome the shortcomings of silicate and phosphate-based ceramics. Calcium silicate (CaSiO3, CS) ceramics are biocompatible and bioactive. In this review, we consider the apatite-forming ability and biological properties of ion-doped CS ceramics such as bredigite, akermanite, monticellite, diopside, merwinite, hardystonite, baghdadite and sphene. Overall, according to the studies conducted on CS bioceramics, all of them may be good candidates for bone tissue regeneration

Abstract

Empty Oil Palm Bunches (EOPB) are waste products from palm oil mills, the waste is produced in large quantities, but most palm oil mills have not utilized this waste product adequately. There are several contents of EOPB, namely cellulose, hemicellulose and lignin, each of which has economic value so that it can be utilized further. One significant opportunity is that cellulose in EOPB will be converted into glucose or bioethanol. Bioethanol is one of the options in supporting the availability of renewable energy resources. The bioethanol production process consists of initial pretreatment, hydrolysis, fermentation and purification. The delignification process of Empty Oil Palm Bunches (EOPB) using physical and chemical pretreatment can break down lignin and hemicellulose so that cellulose can be converted into glucose in bioethanol production. The pretreatment procedure with H2SO4 solvent is used to increase cellulose content. The purpose of this study was to determine how different concentrations of H2SO4 affect the amount of cellulose in the EOPB pretreatment process. Additional studies on bioethanol can be done with this cellulose content. There is an experimental component in this study, namely through direct observation and testing of materials containing different concentrations of H2SO4, namely 3%, 5%, and 7%, data were collected through laboratory experiments. The cellulose content for 0% H2SO4 concentration was 16.15%, 3% H2SO4 was 30.00%, 5% H2SO4 was 36.35%, and 7% H2SO4 was 41.09% indicating that the H2SO4 solvent can increase the cellulose content.

Abstract

Unique and varied bioactive compounds produced by the ocean have drawn attention and served as a focus for creating antibacterial and anti-inflammatory agents. As part of the approach for locating these research sources, databases such as PubMed, Science Direct, MDPI, Google Scholar, Springer Link, Web of Science, Scopus, and Wiley Online Library were used to identify completed studies. Numerous intriguing bioactive compounds have so far been isolated from marine bacteria. A crucial resource in the ongoing search for novel peptides, proteins, lipids, nucleosides, enzymes, alkaloids, polyketides, and terpenoids is the diversity of marine bacterium strains. This review summarizes several bacterial intracellular and extracellular bioactive compounds that have been applied as antibacterial and anti-inflammatory agents in 2016–2024, which we present in the form of structures, species sources, and evaluations of these compounds' antibacterial and anti-inflammatory activities. Therefore, this review article can be used as a recommendation for utilizing biomaterials from marine bacteria that are promising in the future for industrial-scale production of antibacterial and anti-inflammatory agents.

Abstract

In the modern era, electrical energy has become a significant need that drives the large consumption of fossil fuels and their environmental impacts. Supercapacitors can reduce this large consumption of natural polymers such as cellulose acetate (CA), which can be synthesized from Gracilaria sp. Composites with CA can be an environmentally friendly alternative electrode with low toxicity. The results show that the cellulose has been successfully synthesized from the algae Gracilaria sp., which was proven by FTIR spectra analysis. The results also show that supercapacitor electrodes have been successfully made where the manufactured electrodes form a composite between CA and nickel oxide (NiO), with the highest specific capacitance and specific energy values of 15.5 × 102 F/g and 13.3 × 102 Wh/kg, respectively, on the CA-NiO2 electrode, but when the NiO concentration is higher than the CA concentration the specific capacitance and specific energy decrease as shown on the CA-NiO electrode with NiO mass of 0.6 g. Thus, the materials results of this study can be applied to electric vehicles and technology that requires electricity storage in the future.
