Abstract

According to the World Bank study, approximately 17–20% of water contamination is attributed to the textile industry. The quantity of waste produced increases as a result of increased productivity. Textile wastewater contains dyes such as rhodamine B (RhB), which are hazardous and challenging to remove using standard methods. Adsorption utilizing nano-adsorbents has been widely researched and developed to remove dyes from the environment because of its numerous advantages. Graphene oxide-magnetite (GO-Fe3O4) has been extensively explored as an adsorbent due to its large surface area, strong bonding, and ease of separation from water. In this study, GO-Fe3O4 was synthesized by combining GO from coconut shell with Fe3O4 from iron sand as an absorbent to lower the amount of RhB. Various analytical techniques, including XRD, SEM-EDS, TEM, FTIR, and UV-vis, were employed to examine the properties of the composites. The GO-Fe3O4 exhibited a maximum adsorption capacity of 34.590 mg/g under specific conditions, i.e., 0.5 g adsorbent dosage, pH 4, and a 2 h contact time. The adsorption followed the pseudo-second-order kinetics model with 0.00016 mg/g min adsorption rate while the adsorption isotherm followed the Langmuir model where adsorbent surfaces are spread homogeneously by forming a monolayer.

Abstract

Every year, the amount of corn cob waste continues to increase. In Tetey Village, Dimembe District, North Minahasa Regency, North Sulawesi Province, corn cobs are considered to have no significant economic value by the community and are generally only used as animal feed. To address this issue, efforts were made to process corn cob waste into briquettes—an alternative energy source produced from carbon-based materials through a high-temperature pyrolysis process. The utilization of corn cob waste aimed to reduce waste while simultaneously boosting the economy of the people in Tetey Village. This activity was carried out through training and assistance in making briquettes from corn cobs. The preparation and coordination phase involved discussions on training materials and checking the availability of corn cobs in Tetey Village. In the implementation phase, the formulation of corn cob briquettes was analyzed to ensure it met the standards, along with the provision of training materials regarding the manufacturing process. The monitoring and evaluation phase involved measuring the partners' understanding of briquette making before and after the training, as well as analyzing the briquette formulation tested in the laboratory. The results of the assistance showed an increase of more than 60% in the partners' understanding of corn cob briquette production after receiving training. The briquette formulation test showed that using 72% water (v/b from the mass of corn cobs) and 10% tapioca flour (b/b from the mass of corn cobs) could be recommended for the development of corn cob charcoal briquette production by the partners. Setiap tahun, jumlah limbah tongkol jagung terus bertambah. Di Desa Tetey, Kecamatan Dimembe, Kabupaten Minahasa Utara, Provinsi Sulawesi Utara, tongkol jagung dianggap tidak memiliki nilai ekonomi yang signifikan oleh masyarakat, sehingga umumnya hanya dimanfaatkan sebagai pakan ternak. Untuk mengatasi permasalahan tersebut, dilakukan upaya pengolahan limbah tongkol jagung menjadi briket. Briket merupakan sumber energi alternatif yang dihasilkan dari bahan berkarbon melalui proses pirolisis pada suhu tinggi. Pemanfaatan limbah tongkol jagung bertujuan untuk mengurangi limbah yang terbuang percuma sekaligus meningkatkan perekonomian masyarakat Desa Tetey. Kegiatan ini dilaksanakan melalui pelatihan dan pendampingan dalam pembuatan briket dari tongkol jagung. Tahap persiapan dan koordinasi dilakukan melalui diskusi mengenai materi pelatihan serta pengecekan ketersediaan tongkol jagung di Desa Tetey. Pada tahap implementasi, dilakukan analisis formulasi briket tongkol jagung untuk memastikan sesuai dengan standar, serta pemberian materi pelatihan mengenai proses pembuatannya. Tahap monitoring dan evaluasi melibatkan pengukuran pemahaman mitra tentang pembuatan briket sebelum dan sesudah pelatihan, serta analisis formulasi briket yang diuji di laboratorium. Hasil pendampingan menunjukkan peningkatan pemahaman mitra hingga lebih dari 60% mengenai pembuatan briket tongkol jagung setelah menerima pembekalan. Uji formulasi briket arang menunjukkan bahwa penggunaan air sebesar 72% (v/b dari massa tongkol jagung) dan tepung tapioka 10% (b/b dari massa tongkol jagung) dapat dijadikan rekomendasi untuk pengembangan produksi briket arang tongkol jagung oleh mitra.

Abstract

Wastewater treatment is one of the methods used to reduce pollution levels and the harmful effects of wastewater on the environment and human health. Wastewater containing dye substances also has the potential to kill organisms living in the surrounding environment. One solution for treating synthetic wastewater is through the adsorption process. The adsorbent used is derived from corn cobs (Zea mays L.), so the aim of this study is to synthesize and evaluate activated carbon from corn cobs as an adsorbent for methylene blue (MB). To achieve this, the pyrolysis method was employed by placing corn cobs in a furnace heated to 600 °C for 3 hours. The resulting activated carbon was then treated with either H₂SO₄ or NaOH for activation.The produced activated carbon was characterized using X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscope-Energy Dispersive Spectrometry (SEM-EDS) to analyze its crystal structure, functional groups, morphology, and elemental composition. Characterization results revealed that the activated carbon had a small crystallite size and irregular pores. Adsorption tests using a UV-Vis Spectrophotometer demonstrated that corn cob-based activated carbon efficiently adsorbed MB. The highest adsorption efficiency was achieved at a contact time of 90 minutes (99.03%), pH 7 (99.01%), and a concentration of 50 ppm (99.17%) using 0.1 grams of adsorbent. Adsorption isotherm analysis indicated that the process followed the Freundlich isotherm model, suggesting multilayer adsorption on a heterogeneous adsorbent surface.

Abstract

This study reports a green synthesis of copper nanoparticle using binahong (Anredera cordifolia) leaf extract as both a bioreductant and a capping agent. The synthesis was optimized by varying the extract-to-precursor ratio (1:3, v/v) and the reaction pH (6–11) with pH 10 selected as the optimal condition for nanoparticle preparation. Nanoparticle formation was confirmed using UV–Vis spectroscopy, showing a strong absorption band at 325 nm, indicative of oxide-based copper nanostructures and/or surface oxidation during green synthesis. XRD patterns revealed Cu2O as the dominant crystalline phase, characterized by reflections at 2θ ≈ 29.6°, 36.4°, 42.3°, 61.3°, 73.5°, and 77.3°, with a possible minor contribution from metallic Cu due to peak overlap. FTIR spectra confirmed the presence of biomolecules (O–H and C–H bands, along with carbonyl/COO−-related bands) involved in nanoparticle stabilization, as well as Cu–O vibrations around 600–620 cm−1 consistent with Cu2O. PSA showed a dominant hydrodynamic size in the 60–70 nm range (average 65 nm), whereas SEM indicated aggregation into micrometer-scale clusters upon drying. In vitro α-amylase inhibition assays demonstrated concentration-dependent inhibition, with CuNPs (IC50 6.18 μg/mL) and the extract + CuNPs mixture (IC50 6.83 μg/mL) approaching that of acarbose (IC50 5.04 μg/mL) and exhibiting stronger activity than the extract alone (IC50 8.89 μg/mL). The key contribution of this work is the development of a simple, aqueous, environmentally friendly route that leverages local biological resources while producing Cu2O-rich nanoparticles with α-amylase inhibitory activity approaching that of acarbose. These findings highlight the promise of a low-cost antidiabetic candidate for postprandial glucose control and provide a basis for further investigations into nanoformulation and preclinical evaluation.

Abstract

ABSTRAK Logam berat kadmium adalah salah satu polutan yang dapat masuk perairan melalui buangan berbagai industri yang terus berkembang. Di beberapa tempat di Indonesia, polutan ini telah terdeteksi dalam jumlah yang melebihi nilai ambang sehingga perlu terus dilakukan upaya untuk mengeliminasi logam berat dari perairan. Salah satu metode yang telah diketahui cukup efektif dan ekonomis adalah adsorpsi dan upaya untuk mengembangkan adsorben logam berat masih terus dilakukan. Dalam penelitian ini telah dilakukan modifikasi tulang ikan cakalang  yang mengandung hidroksiapatit dengan magnesium untuk mendapatkan material adsorben yang lebih baik. Modifikasi dilakukan melalui reaksi tulang ikan dengan magnesium hidrogen fosfat dalam asam fosfat pada pH 2,3 dan kemudian dikalsinasi pada 600 oC. Material yang diperoleh kemudian dikarakterisasi dengan teknik XRD, SEM, dan XRF dan dievaluasi adsorpsinya dengan model adsorpsi Langmuir dan Freundlich. Karakterisasi dengan teknik XRD mengindikasikan terbentuknya whitlokit, suatu biomineral yang jarang ditemui dan diketahui memiliki karakter yang lebih baik dari hidroksiapatit. Evaluasi adsorpsi menunjukkan bahwa material hasil modifikasi memiliki kapasitas adsorpsi yang lebih besar dibanding dengan tulang ikan tidak termodifikasi. ABSTRACT Cadmium is a pollutant that can enter aquatic environments through waste discharged from various growing industries. In several locations across Indonesia, this pollutant has been detected in quantities exceeding the maximum permissible threshold, necessitating continuous efforts to eliminate heavy metals from waters. Adsorption is known as a highly effective and economical method, and efforts to develop heavy metal adsorbents are still ongoing. In this study, skipjack tuna bone containing hydroxyapatite was modified with magnesium to obtain a superior adsorbent material. The modification was performed through the reaction of fish bone with magnesium hydrogen phosphate in phosphoric acid at pH 2.3, followed by calcination at 600 °C. The resulting material was then characterized using XRD, SEM, and XRF techniques, and its adsorption performance was evaluated using the Langmuir and Freundlich adsorption models. Characterization by XRD indicated the formation of whitlockite, a rare biomineral known to possess better characteristics than hydroxyapatite. The adsorption evaluation demonstrated that the modified material exhibited a higher adsorption capacity compared to the unmodified fish bone.
