Abstract

Abstrak Kontaminan gas merupakan masalah besar pada proses industri dan lingkungan, terutama hidrogen sulfida (H2S). Gas ini tidak berwarna, tidak berbau, korosif terhadap jaringan pipa gas alam, merusak katalis logam, dan menyebabkan hujan asam. Selain itu, gas ini sangat mudah terbakar dan sangat beracun, sehingga perlu dihilangkan meskipun dalam konsentrasi kecil. Salah satu metode untuk menghilangkan H2S, yang belum dipelajari secara luas, adalah oksidasi dengan kalium permanganat (KMnO4) yang diimpregnasikan pada karbon berpori atau dinamai nano-confinement KMnO4. Cangkang sawit (PKS) digunakan sebagai bahan baku karbon berpori, yang melimpah, terbarukan, dan murah. Proses produksi nano-confinement KMnO4 terdiri atas eberapa langkah. Langkah pertama adalah pirolisis cangkang sawit dalam tungku pada suhu 800°C, diikuti oleh aktivasi karbon uap. Ini menghasilkan karbon berpori cangkang sawit (CPKS). Tahap kedua adalah pembuatan karbon berpori dari cangkang sawit yang cenderung hidrofilik dengan cara oksidasi praperlakuan menggunakan ozonasi basah, yang selanjutnya dinamakan CKPS-Oz. Kalium permanganat yang teremban dalam karbon berpori dari cangkang sawit (KMnO4/CPKS-Oz) diproduksi dengan cara impregnasi secara basah variasi KMnO4 sebesar 5, 10, dan 20% wt. Hasil uji kinerja menunjukkan bahwa KMnO4/CPKS-Oz mampu menghilangkan H2S hingga 98% dan lebih efektif dibandingkan hanya menggunakan KMnO4 (67%). Penelitian ini menunjukkan bahwa kombinasi antara oksidasi ozon basah dan impregnasi KMnO₄ ke dalam karbon aktif dari tempurung kelapa sawit (CPKS) menghasilkan peningkatan kapasitas oksidasi gas H₂S secara signifikan. Metode ini merupakan pendekatan baru yang belum banyak dilaporkan dalam pemanfaatan CPKS untuk penghilangan gas H₂S   Abstrak A gas contaminant is a big problem in the process industry and environment, especially hydrogen sulfide (H2S). It is colorless, odorless, corrosive to natural gas pipelines, damages metal catalysts, and causes acid rain. Moreover, it is extremely flammable and highly toxic, so it needs to be removed even in small concentrations. One method to remove H2S, which has yet to be studied widely, is oxidation by nano-confinement permanganate potassium (KMnO4) in a porous carbon support. Palm kernel shells (PKS) were used as a raw material of porous carbon, which is abundant, renewable, and cheap. The production process of nano-confinement KMnO4 consists of several steps. The first step is the pyrolysis of palm kernel shells in the furnace at 800°C, followed by steam activation of carbon. It produced palm kernel shells porous carbon (CPKS). The second step was to produce porous carbon of palm kernel shell that tends to be hydrophilic by pretreatment oxidation using wet ozone treatment, which was then named CKPS-Oz. Potassium permanganate confined in porous carbon from palm kernel shell (KMnO4/CPKS-Oz) was produced by incipient wet-impregnation with KMnO4 variations of 5, 10, and 20%wt. The performance test showed that KMnO4/CPKS-Oz could remove H2S up to 98% and was more effective than only using KMnO4 (67%). This work presents a novel synergistic strategy by integrating wet ozone oxidation and KMnO₄ confinement within palm kernel shell–derived porous carbon (CPKS), providing a sustainable and highly efficient material tailored explicitly for hydrogen sulfide (H₂S) removal from gas streams.

Abstract

The study of carbonaceous electrode materials for supercapacitors is expanding and remains challenging. Chitosan is one of the many biomasses found in nature that can be converted into porous carbon for electrode materials in supercapacitors. Despite having a high specific surface area and good chemical stability, porous carbons have a limitation of specific capacitance. On the other hand, polyaniline (PANI), a conductor polymer, typically exhibits high specific capacitance but has low stability. Thus, a binary nanocomposite of chitosan-derived porous carbon (CCS) and PANI is suggested to obtain an optimal performance. Porous carbon was produced from chitosan through two steps: (i) hydrothermal carbonization; (ii) chemical activation using steam at a temperature of 800 °C for 2 hours. The CCS was then oxidized with diluted H2O2 to increase surface wettability. Binary nanocomposites were produced by a nanocompositing method of in situ polymerization of PANI with a variation of 5% (CCS/PANI5%), 10% (CCS/PANI10%), and 15% (CCS/PANI15%). The materials were characterized by scanning electron microscopy–energy dispersive X-ray (SEM-EDX), Fourier-transform infrared (FTIR), N2-sorption analysis, and thermogravimetric analysis (TGA). Meanwhile, electrochemical tests were performed using a three-electrode method to obtain cyclic voltammetry and the capacitance of each sample. The N2-sorption analysis showed that the surface area of samples CCS, CCS/PANI5%, CCS/PANI10%, and CCS/PANI15% are 1305 m2.g-1, 430 m2.g-1, 333 m2.g-1, and 238 m2.g-1, respectively. SEM-EDX, FTIR, and TGA proved that PANI is loaded in the carbon surface. From the electrochemical tests conducted at a scan rate of 5 mV.s⁻¹, the specific capacitance values for the samples CCS, PANI, CCS/PANI5%, CCS/PANI10%, and CCS/PANI15% were determined to be 220.27 F.g⁻¹, 143.81 F.g⁻¹, 330.42 F.g⁻¹, 434.73 F.g⁻¹, and 391.27 F.g⁻¹, respectively. The CCS/PANI10% sample exhibited the highest specific capacitance of 434.73 F.g⁻¹, corresponding to an energy density of 86.9 Wh.kg⁻¹ and a power density of 1.3 kW.kg⁻¹. These significant enhancements in specific capacitance underscore the effectiveness of the nanocomposite approach and highlight its potential for improving electrode performance. As a result, the chitosan-based porous carbon and polyaniline nanocomposite developed in this study is a promising candidate for supercapacitor electrode materials.

Abstract

Urea is the main source of nitrogen for plants. Conventional urea fertilizer is made by reacting ammonia and carbon dioxide. Wastewater produced by urea fertilizer plants usually contains urea and ammonia in high concentrations. In each m3 of wastewater urea content can reach 650 - 4000 ppm and ammonia amounting to 100 - 1300 ppm. The disposal of wastewater that still contains urea and ammonia with high levels can cause eutrophication in waters which is very detrimental to aquatic organisms. The uptake of urea in the urea fertilizer plant wastewater is an interesting study because it can provide a double benefit of reducing the concentration of urea in wastewater so that it can meet environmental quality standards that are environmentally friendly and obtain cheap urea fertilizer for plants. This study aims to determine the adsorption capacity of urea with porous carbon if there is ammonia in the liquid. Porous carbon is made from pyrolysis of coconut shell which is oxidized with sulfuric acid. The oxidation process is carried out by heating porous carbon which is immersed in a 50% w/w sulfuric acid solution at 90oC for 2 hours. The adsorption process is carried out at room temperature with an initial concentration of urea between 500 - 8000 ppm in a solution of urea-ammonia as a simulated liquid. The results showed that the urea adsorption capacity increased significantly in urea-ammonia solution compared to urea solution with an increase of 41%. The capacity of urea adsorption in urea-ammonia solution is 27 - 444 mg urea / g carbon.

Abstract

The influence of cutting conditions on power consumption in turning machines is affected by various factors, such as spindle speed, the material being machined, depth of cut, and the tool used during the turning process. This study aims to obtain data on electrical energy consumption in relation to the spindle speed (RPM) settings and depth of cut during the turning process. In this study, the material used is ST-40 steel. The power consumption is obtained from theoretical calculations based on the current data measured empirically during the turning process. With varying spindle speeds of 65 rpm, 180 rpm, and 235 rpm at a cutting depth of 1 mm, the current data measured were 2.25 Amp, 2.12 Amp, and 1.98 Amp, respectively. For a cutting depth of 2 mm, the current measured was 2.46 Amp, 2.27 Amp, and 2.13 Amp. Therefore, the theoretical power obtained at a cutting depth of 1 mm was 1035.41 Watts, 975.58 Watts, and 911.16 Watts. At a cutting depth of 2 mm, the power consumption was 1132.04 Watts, 1044.61 Watts, and 980.18 Watts. The conclusion of this study is that as the spindle speed (RPM) increases, power consumption decreases, while deeper cutting increases the electrical energy required.Pengaruh kondisi pemotongan terhadap pemakaian daya listrik pada mesin bubut dipengaruhi banyak faktor, misalnya kecepatan putaran spindle, material yang dikerjakan, kedalaman pemakanan, dan pahat yang dilakukan pada saat proses pembubutan. Penelitian pada bertujuan untuk memperoleh data konsumsi energi listrik terhadap setting putaran (Rpm) dan kedalaman pemotongan pada proses pembubutan. Pada penelitian ini material yang digunakan adalah ST-40. Konsumsi daya listrik diperoleh dari perhitungan teoritis dari data kuat arus listrik yang dilakukan secara empiris pada saat proses pembubutan berlangsung. Dengan variasi kecepatan putaran 65 rpm, 180 rpm dan 235 rpm kedalaman 1 mm didapat data 2.25 Amp, 2.12 Amp, dan 1.98 Amp. Dan 2.46 Amp, 2.27 Amp dan 2.13 Amp pada kedalaman pemakanan 2 mm. Sehingga daya teoritis yang didapat pada kedalaman pemotongan 1 mm adalah 1035.41 Watt, 975.58 Watt, dan 911.16 Watt. Dan pada kedalaman 2 mm didapat 1132.04 Watt, 1044.61 Watt dan 980.18 Watt. Dari penelitian ini menunjukkan semakin kecepatan putar (Rpm) bertambah konsumsi energi listrik semakin kecil, dan makin dalam pemotongan semakin menambah kebutuhan energi listrik.
