Abstract

Activated carbon can be manufactured from a variety source materials containing element carbon. Dregs of coffee grounds is one of abundant and promising activated carbon raw materials. This study was conducted to assess optimization process of activated carbon production from dregs of coffee grounds by using ZnCl2 as an activator. The optimization process is performed by using Response Surface Method to optimize factors that affected quality of the activated carbon using Box-Behnken design. The factors used were carbonation temperature (T) with a level of 400 oC, 500 oC and 600 °C; concentration of ZnCl2 (K) with a level of 30%, 40%, 50%; and mass ratio of ZnCl2 to activated carbon with level of 2:1, 3:1 and 4:1. A second order regression model of iodine absorption of activated carbon was Y = 626,2 - 36,5T + 28,6K - 36,5R + 31,2T2 + 47,1K2 - 0,5R2 - 19,0TK + 15,9TR + 101,5KR. Results of optimization process showed that optimum iodine absorption of 799.659 mg/g was obtained at the following conditions, i.e. carbonation temperature of 400 oC, ZnCl2 concentration of 30% and mass ratio of ZnCl2 to activated carbon of 2:1.

Abstract

The pollution caused by mercury (Hg) is a matter of concern regarding worldwide ecosystems and public health. It is dangerous as it is highly poisonous and has more ways to get exposed than other heavy metal ions. Recently, the application of biomaterials with varying structures and designs for mercury adsorption has grown. In this research, clay monoliths (CM) and clay-manganese monoliths (CMM) were synthesized, investigated, and compared regarding their ability to adsorb mercury ions from water to determine the most effective adsorbents. CM and CMM were extruded through a stainless-steel molder with dimensions of 7 holes, 9 mm in radius, and 20 mm in height. The surface morphologies of both adsorbents were characterized using infrared (IR) spectroscopy and scanning electron microscopy (SEM). The effects of contact time (40, 80, 120, 160, 200, and 240 minutes) and initial concentrations (3–5 mg/L) were applied to evaluate both adsorption processes. The experiment was conducted in a batch reactor using a monolithic adsorbent that operated for 240 minutes. The experimental equilibrium data of the adsorption were examined with Langmuir and Freundlich models to find the best-fit isotherm. In the kinetic study, the pseudo-first-order was investigated in both linear and nonlinear models. The adsorption results showed that CMM had the highest adsorption efficiency (42.7%). The equilibrium study concluded that the Langmuir was the most significant isotherm model. The highest monolayer capacity and Langmuir constants (KL and aL) were 0.396, 1.329, and 0.396, respectively. The adsorption of both adsorbents was well displayed in the pseudo-first-order non-linear model. Experiments and processed data compromise the finding that CMM is more effective than CM at adsorbing mercury ions.

Abstract

Triacetin, an alternative biodiesel additive, was prepared by esterification of glycerol with acetic acid in the presence of chemically activated natural zeolite. The esterification was carried out in a small reaction flask under microwave irradiation. The catalyst was characterized for its morphology by SEM and its chemical composition by X-ray Diffraction (XRD). The Scanning Electron Microscopy (SEM) micrograph indicates improved surface area of the zeolite, while the XRD analysis shows an increase in Si/Al ratio from natural zeolite to 6.042 and its crystallinity value of 12.23%. The Fourier Transform Infra Red (FTIR) analysis obtained showed that microwave-heated samples have an esters group spectrum of triacetin at 1702 cm-1. The conversion value of glycerol was more than 95% at molar ratio of the reactants 1:9 and catalyst loading of 3%. The selectivities for monoacetin, diacetin and triacetin were 80.1%, 15.4%, and 4.5% at 60 minutes, and 43.0%, 48.6%, and 8.3% at 90 minutes. It shows that the conversion took place in consecutive steps and the use of microwave allows the reaction proceeding at milder condition.

Abstract

Abstract:  In recent years, the presence of heavy metals in water has been a concern, and some purification processes have been developed to overcome these problems. This study aims to conduct and investigate the performance of the 3 modifications of adsorbents namely clay-carbon, clay-carbon manganese monolith 2% and clay-carbon manganese monolith 5% in adsorbing Pb2+ ions in water. The surfaces and elemental compositions of the two adsorbents were investigated by a scanning electron microscope and Fourier infrared transform. The variables evaluated in analyzing the adsorption efficiencies were the effect of contact time (0, 150, 180, 210, and 240 minutes), MnO2 doses in monolith (2 and 5% weight) and initial Pb2+ ion concentrations (2 and 4 mg/L). The adsorption behaviour in the equilibrium stage was observed through the isotherms (Freundlich, Langmuir, and Brunauer–Emmett–Teller (BET)) and kinetics study (pseudo-first and pseudo-second order linear-non linear models). The impregnation of manganese into the adsorbent showed significant results in adsorption. The maximum adsorption efficiency was 92.92% in a Pb2+ solution of 4 mg/L utilizing clay-carbon-manganese monolith at a contact time of 240 minutes. Meanwhile, the clay-carbon monolith efficiency was 50.59%. Thus, the modification biomass material with the impregnation of metal such as clay-carbon-manganese monolith can be used as a potent, reusable, and durable adsorbent in removing metal ions in water and wastewater.Abstrak: Dalam beberapa tahun terakhir, keberadaan logam berat dalam air masih menjadi perhatian dan beberapa proses pemurnian dikembangkan untuk mengatasi masalah ini. Adsorpsi adalah proses yang efisien dan murah untuk mengolah air yang mengandung logam berat. Penelitian ini bertujuan untuk melakukan dan menyelidiki kinerja monolit tanah liat-karbon dan tanah liat-karbon mangan dalam mengadsorpsi ion Pb2+ dalam air. Permukaan dan komposisi unsur dari dua adsorben diselidiki dengan mikroskop elektron dan transformasi inframerah fourier. Variabel yang dinilai dalam analisis efisiensi adsorpsi adalah pengaruh waktu kontak (0, 150, 180, 210 dan 240 menit), dosis MnO2 dalam monolit (2 dan 5% berat) dan konsentrasi ion Pb2+ awal (2 dan 4 mg/L). ). Perilaku adsorpsi pada tahap kesetimbangan diamati melalui isoterm (Freundlich, Langmuir dan Brunauer–Emmett–Teller (BET)) dan studi kinetika (model linier-non linier orde satu semu dan semu dua). Impregnasi mangan ke dalam adsorben menunjukkan hasil yang signifikan dalam adsorpsi. Efisiensi adsorpsi ion Pb2+ tertinggi diperoleh 92,92% pada konsentrasi larutan 4 mg/L dengan penggunaan monolit lempung-karbon-mangan pada waktu kontak 240 menit. Sedangkan efisiensi clay-carbon monolit sebesar 50,59%. Perilaku adsorpsi ion Pb2+ baik pada karbon lempung maupun monolit karbon-lempung-mangan paling sesuai dengan model orde satu non linier dan isoterm Langmuir, dimana adsorpsi terjadi pada permukaan adsorben monolayer. Dengan demikian, bahan biomassa modifikasi dengan impregnasi logam seperti monolit tanah liat-karbon-mangan dapat digunakan sebagai adsorben yang kuat, dapat digunakan kembali, dan tahan lama dalam menghilangkan ion logam dalam air dan air limbah.

Abstract

This paper proposed adsorbent development by synthesizing polyurethane foam (PUF) using a simple method, mixing polyol with isocyanate and adding fillers of bentonite and magnetite to the PUF matrix. The study's main objective was to produce a PUF-based adsorbent with high reactivity to removeHg2+ in wastewater. This bentonite and magnetite filler-modified polyurethane foam (BMPUF) adsorbent was fixed in a bed column for the adsorption of mercury (II) ions from an aqueous solution. The effect of initial Hg2+ concentration on the removal rate and the effect of contact time on adsorption efficiency was investigated. Langmuir, Freundlich, and BET non-linear models were taken into account to determine the best adsorption isotherm fitting and obtain adsorption capacity, intensity, and pore volume. As a result, it followed the non-linear Freundlich model, and the average adsorption capacity and intensity were 0.466 mg/g and 0.923, respectively. The average BET-based pore volume obtained was 0.782 L/mg. The kinetics study showed that the non-linear pseudo-first-order kinetics model was more suitable for describing the Hg2+ adsorption kinetics. The maximum equilibrium adsorption capacity was 1.770 mg/g with the adsorption rate of 0.0013 min-1 based on the non-linear model. The effect of varying bentonite and magnetite ratio on adsorption isotherm and kinetics was also investigated. Overall, the potential application of BMPUF adsorbent in the adsorption of mercury (II) ions was demonstrated in the current study.

Abstract

The software helps solve things faster, e.g., Epanet software, Pipe Flow Expert, WaterCAD, SAP2000 planning software, etc. Likewise, in the field of calculating traffic volume with the development of artificial intelligence technology, using video recording, volume, and speed calculations can be done easily. At this time, the classification of traffic counting is only up to 3 (three) types of vehicles classified by YOLO V8, so in this research, the classification is added to be 6 (six) types of vehicles, namely mini cars, mobile passengers, small buses, big buses, small trucks, and large trucks, according to vehicle classification established in Indonesia. The research method is done by recording the traffic on the road and then video recording with the help of the software developed with the Python program so that the volume of the vehicle according to its classification is obtained. The result obtained from this research is compared to the manual traffic counting. The comparison between vehicle counting by the software and manual counting is mini-car 97.02%, passenger car 99.49%, small bus 96.94%, large bus 97.34%, small truck 93.21%, and large truck 97.18%.

Abstract

This study presents a sustainable approach to water dye decontamination using monoliths constructed from candlenut shells, clay, and molasses as a binder. The candlenut shells were activated to form carbon and then mixed with natural clay and molasses to create the monolith composite. The dough was pushed through a stainless-steel mold featuring seven circular openings, each measuring 2 cm in width and 2 cm in thickness, to create the monoliths (MCC and MMCC). The monoliths were rigorously tested for adsorption efficiency, isotherm behavior, and kinetic properties. Results showed a high dye removal efficiency, with 92% for methylene blue and 74% for methyl orange, which was attributed to the stronger interaction of methylene blue with the negatively charged surface of the monoliths. The isotherm analysis followed the Langmuir model, indicating monolayer adsorption on uniform active sites. Kinetic studies using linear regression analysis aligned with the pseudo-second-order model, indicating that chemical adsorption was the controlling factor in the rate. Characterization of the monoliths using Scanning Electron Microscopy (SEM) revealed a porous surface morphology, while X-ray Diffraction (XRD) identified the crystalline structures present. Fourier Transform Infrared Spectroscopy (FTIR) confirmed the presence of functional groups essential for dye adsorption, and Brunauer-Emmett-Teller (BET) analysis determined the specific surface area and pore size distribution. In conclusion, this study underscores the viability of using candlenut shell and clay-derived monoliths as efficient and environmentally friendly adsorbents for wastewater treatment, providing a practical solution to dye pollution.

Abstract

Pembelajaran matematika bagi siswa tunanetra merupakan tantangan tersendiri dalam dunia pendidikan inklusif. Hal ini disebabkan oleh karakteristik matematika yang sangat bergantung pada representasi visual, seperti simbol, grafik, dan bentuk-bentuk geometri. Tunanetra, sebagai individu yang mengalami hambatan dalam penglihatan, memerlukan strategi dan media pembelajaran yang berbeda dengan siswa awam. Salah satu solusi yang dapat diterapkan adalah penggunaan media taktil dan sistem tulisan Braille dalam pembelajaran matematika. Penelitian ini bertujuan untuk mengkaji efektivitas media taktil dan huruf Braille dalam meningkatkan kemampuan belajar matematika siswa tunanetra melalui studi observasi pada siswa kelas 2 SD di SLB Bunda Mulia, Kabupaten Ngawi, serta tinjauan pustaka dari penelitian sebelumnya. Metode penelitian menggunakan pendekatan kualitatif deskriptif dengan teknik observasi, wawancara, dan studi dokumentasi. Hasil observasi menunjukkan bahwa media konkret seperti bentuk bangun datar timbul dan reglet-stylus untuk menulis Braille sangat membantu siswa dalam memahami konsep-konsep dasar matematika. Namun, kesulitan masih muncul pada aspek motorik halus, terutama saat membaca dan menulis huruf Braille serta memahami arah dan posisi titik. Penggunaan strategi pembelajaran yang memadukan media taktil, pelatihan motorik, serta pendekatan multisensori terbukti dapat meningkatkan partisipasi aktif dan motivasi belajar siswa tunanetra.
