Abstract

ABSTRAKPenelitian ini adalah penelitian eksplorasi yang bertujuan untuk mengisolasi dan identifikasi senyawa metabolit sekunder yang terdapat dalam ekstrak kloroform daun Manilkara zapota. yang berasal dari Kecamatan Tempe Kabupaten Wajo Sulawesi Selatan. Isolasi dilakukan dalam beberapa tahap yaitu maserasi, partisi dengan kloroform, fraksinasi, uji kemurnian dan identifikasi. Hasil penelitian diperoleh isolat murni berupa serbuk berwarna putih dengan titik leleh 140-142oC. Hasil uji dengan pereaksi Liebermann-Buchard mengalami perubahan warna dari bening menjadi hijau menunjukkan positif steroid. Isolat diidentifikasi dengan menganalisis spektrum infra merah yang menunjukkan bilangan gelombang (cm-1) yakni: 3442,94 (-OH terikat); 2947,23 dan 2873,94 (-CH alifatik); 1732,08 (C=O karboksilat); 1249,87 dan 1026,13 (C-O alkohol). Berdasarkan hasil analisis dan penelusuran literature adalah senyawa golongan steroid.Kata kunci : Isolasi, M. zapota, Steroid. ABSTRACTThis is an exploratory research that aims to isolate and identify secondary metabolite compound contained in cloroform Extract of Manilkara zapota leaves from Tempe, Wajo, South Sulawesi. The isolation was done through several stages: maceration, partition with cloroform, fractionation, purity testing, and identification. The extract was found to contain white powder of pure isolate with a melting point of 140-142oC. The test result using Liebermann-Buchard reagent exhibited a shift of color from transparent into green, therefore it can be categorized as a positive steroid. The isolate was identified by analyzing the infra red spectrum which showed wave numbers (cm-1) of: 3442.94 (-OH bond); 2947.23 and 2873.94 (-CH aliphatic); 1732.08 (C=O carboxylate); 1249.87 and 1026.13 (C-O alcohol).

Abstract

The noodle-making training from dragon fruit peel waste (Hylocereus polyrhizus) in Gona Village, Kajuara Subdistrict, is a community service initiative aimed at developing local potential. About 20 members of the Gona Village community in Kajuara Subdistrict attended the socialization activity. The community participated in a socialization session regarding the nutritional content and product development based on dragon fruit peel. Organoleptic testing results of the product indicated that dragon fruit peel noodles were generally considered good by most people. Based on the results of this community service, it can be concluded that dragon fruit peel waste can be processed into noodles that have nutritional and economic value, which can be utilized to improve nutrition and income for the community in Gona Village.

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

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

Nanocellulose, a sustainable and biodegradable material derived from natural cellulose, holds immense potential for addressing global environmental challenges. This article reviews the production methods, structural modifications, and applications of nanocellulose derivatives in environmental contexts, emphasizing their role in water purification, pollutant adsorption, and renewable energy solutions. The systematic literature review highlights the unique properties of nanocellulose, such as high mechanical strength, large specific surface area, and tunable chemical functionalities, which enable its use in various industrial, biomedical, and environmental applications. Results indicate that nanocellulose-based materials outperform conventional materials in efficiency and sustainability, particularly in water treatment and biodegradable packaging. Despite its advantages, challenges remain, including production costs, dispersibility in polymer matrices, and stability under high humidity. These limitations necessitate further research and collaborative innovation to enhance its applicability and affordability.

Abstract

In the face of climate change challenges and declining fossil energy resources, bioethanol is emerging as an environmentally friendly renewable energy solution. This article aims to review the potential, opportunities, and challenges in utilizing agricultural waste as the main raw material for bioethanol production. By analyzing various recent studies, it is found that agricultural wastes such as rice straw, corn cob, and bagasse have significant carbohydrate content for conversion into ethanol. Second-generation bioethanol production technologies utilizing lignocellulose offer higher efficiency than previous generations but face technical and economic challenges, including complex pretreatment requirements and high production costs. This review shows that bioethanol utilization can reduce dependence on fossil fuels while providing a sustainable solution for waste management. Policy support, technological innovation, and cross-sector collaboration are needed to accelerate the development of agricultural waste-based bioethanol, especially in developing countries such as Indonesia.

Abstract

Penelitian dengan judul "Analisis Kandungan Minyak Nabati Menggunakan Metode Ekstraksi Kontinyu", bertujuan untuk menganalisis kandungan minyak nabati dari beberapa sampel dengan menggunakan metode ekstraksi kontinyu soxletasi. Sampel yang digunakan adalah biji labu, biji melon, biji jarak, kemiri, kacang tanah, dan biji coklat. Petroleum eter digunakan sebagai sebagai pelarut dalam proses ekstraksi kontinyu dipilih karena sifat non-polar yang efektif dalam mengekstrak senyawa non-polar seperti lemak dan minyak dari bahan tumbuhan. Hasil ekstraksi yang diperoleh memperlihatnkan bahwa ekstraksi minyak nabati pada kemiri memberikan hasil perhitungan massa jenis yang sama dengan beberapa penelitian ektraksi minyak kontinyu dari kemiri yang telah dilakukan yaitu sebesar 0,9218 gr/mL. Hasil rendemen  ekstraksi dari kemiri menunjukkan hasil yang tinggi dibandingkan dengan sampel lainnya sebesar 30,42%.
