Topics: Chemical Engineering; Catalysis
Abstract: Fischer-Tropsch Synthesis (FTS) using Fe-Co/meso-HZSM-5 catalyst has been investigated. The impregnated iron and cobalt on HZSM-5 could be used as bifunction catalyst which combined polimerizing synthesis gas and long hydrocarbon cracking for making biofuel (saturated C5–C25 hydrocarbons as gasoline, kerosene and diesel oil). The study emphasized the effect of catalyst weight on product composition and process conversion. The HZSM-5, had been converted from ammonium ZSM-5 through calcination, and then desilicated with NaOH solution. The Co(NO3)2⋅6H2O and Fe(NO3)3⋅9H2O were used as precursor for incipient wetness impregnation (IWI) on amorphous meso-HZSM-5. The catalyst consisted of 10 % Fe and 90 % Co by weight, called 10Fe-90Co/meso-HZSM-5. All catalysts were reduced in situ in the continuous reactor with flowing hydrogen at 25 mL/min, 1 bar, 400 °C for 10 hours. The catalyst performance was observed in the same continuous fixed bed reactor at 25 mL/min synthesis gas (30 % CO, 60 % H2, 10 % N2), 250 °C, 20 bar for 96 hours. Various catalyst weight (1, 1.2, 1.4, 1.6 gram) were applied in FTS. The desilicated HZSM-5 properties (BET analysis) were 6.1–29.9 nm mesoporous diameter, 0.3496 cc/g average mesoporous volume, 526.035 cc/g pore surface area, and the EDX analysis gave 22.1059 Si/Al ratio and 16.11 % loading (by weight) on meso-HZSM-5. The reduced catalyst showed the XRD spectra of Fe (66°), Fe-Co alloy (44.50°) and Co3O4 (36.80°).

Abstract: Pengajuan praperadilan yang diajukan lebih dari satu kali masih diterima oleh hakim. Hal ini terjadi karena tidak adanya aturan yang tegas membahas tentang pengajuan praperadilan lebih dari satu kali di dalam KUHAP. Pelaksanaan praperadilan lebih dari satu kali belum berlandaskan pada hukum positif dan bertentangan dengan asas-asas dan teoriteori hukum seperti keadilan posedural, kepastian hukum, asas legalitas dan asas peradilan sederhana, cepat dan biaya ringan. Asas nebis in idem memiliki arti bahwa orang yang sudah diadili atau dijatuhi hukuman yang sudah memiliki kekuatan yang mengikat yang pasti oleh badan peradilan yang berwenang atas suatu kejahatan atau tindak pidana yang dituduhkan kepadanya, tidak boleh diadili atau dijatuhi putusan untuk kedua kalinya atau lebih, atas kejahatan atau tindak pidana, tempat kejadian dan waktu (locus delicti dan tempus) yang sama.

Abstract: Usability evaluation focuses on how well users can learn and use products to achieve their goals. Evaluation of e-commerce website usability can be done using the Fuzzy Analytical Hierarchy Process (FAHP) method. Usability is considered a multi-criteria problem due to its complex structure. Logarithmic Fuzzy Preference Programming (LFPP), a non-linear programming approach, is one of the FAHP methods for weighting criteria. However, deficiencies in the LFPP method, in some cases, result in a consistency value of 0 from a consistent fuzzy comparison matrix, which should be greater than 0. This study modifies the LFPP method with the Modified LFPP (MLFPP) models. Modifications were made as a development of the LFPP method in improving the accuracy of the consistency index (𝜆∗) before weighting criteria. The MLFPP makes improvements to the functional constraints, while at the same time improving the determination of criteria weights. The MLFPP model uses arctan to limit functions to improve consistency index. The test results show that the MLFPP can improve the accuracy of the consistency index values in the pairwise comparison matrix given by experts to be more than 0, with an average increase of 14.9%. The amount of consistency index (𝜆∗) changes has improved the usability score by 6.59%.

Abstract: Rockfill dams have better stability than homogeneous soil dams. It allows to design the dam more slim with a higher slope. The disadvantage of rockfill dam is in the core zone as an impermeable zone. Zoned vertical core rockfill dam is a combination of various material properties. Geometry and drainage design will affect the seepage and phreatic line properties that occur. Numerical modeling and calculations are used to calculate the seepage profile more accurately. The combination of the parameters of the permeability coefficient (K), reservoir water level (Δh) and the length of the seepage path (L) can be used to determine the relationship between parameters with the same unit. 2D modeling take into account saturated/unsaturated conditions with steady state on each parameter. This study uses the Jatibarang-Indonesia dam as a basic model. The seepage profile at condition K1 (k= 1x10-5cm/sec) is q/k=-0.0018 (h2/L) 2+ 1.3496 h2/L+ 53.241 and the seepage profile K2 (k= 1x10-7cm/s) is q/k=-0.1521 (h2/L) 2+ 90.402 h2/L+ 5480.2. This equations can be used to estimate seepage that occurs in a dam of other rock fill zoned vertical core dam based on the permeability coefficient value (K) more practically for all values of Δh and L reviewed.

Abstract: Keruntuhan bendungan merupakan sumber potensi bahaya terbesar pada sebuah bendungan. Rencana Tindak Darurat (RTD) merupakan syarat yang harus dipenuhi oleh operator bendungan sebelum bendungan tersebut beroperasi. Analisa keruntuhan bendungan tidak dimaksudkan untuk mendesain ulang bendungan agar lebih kuat, tetapi untuk memperkirakan potensi resiko jika terjadi kegagalan bendungan. Makalah ini fokus pada analisis geospasial dan analisis hidrolik yang terjadi pada daerah hilir bendungan ketika terjadi kegagalan bendungan. Sebagai studi kasus penelitian ini adalah Bendungan Logung yang berada di Kudus, Indonesia. Bendungan ini mempunyai kapasitas 20jt m3 dengan ketinggian bendungan 55m pada DAS Muria. Dam Break Analysis (DBA) dimodelkan 2D pada kondisi unsteady-flow menggunakan HEC-RAS dan HEC-GeoRAS. Analisis spasial dan analisis hidrologi digunakan sebagai input dalam pemodelan tersebut. Output dari Dam Break Analysis ini adalah peta dinamis 2D yang memberikan informasi debit, kecepatan, luasan dan kedalaman pada setiap titik yang terdampak runtuhnya bendungan. Informasi tersebut dapat digunakan untuk rencana mitigasi dan proses evakuasi dalam Emergency Action Plan (EAP), sehingga dapat meminimalisir resiko ketika bencana tersebut terjadi.

Abstract: Penelitian ini berkaitan dengan pengembangan bahan alam dari zeolit alam, sekam padi dan ampas tebu. Modifikasi bahan alam dilakukan dengan menggunakan cetyltrimethyllammonium bromide (CTAB) sebagai surfaktan kationik untuk templat mesopori. Karakter fisikokimia bahan alam yang termodifikasi dan tanpa modifikasi diselidiki dengan menggunakan XRF, XRD, FTIR, fisisorpsi nitrogen, dan SEM-EDX. Kandungan utama dari bahan alam adalah Silika (Si) yang dibuktikan dari analisis XRF. Analisis XRD menunjukkan bahwa modifikasi dengan penambahan surfaktan dapat menyebabkan penurunan kristalinitas zeolit alam dan ampas tebu, sedangkan kristalinitas sekam padi meningkat. Munculnya pita serapan spesifik pada hasil karakterisasi menggunakan FTIR menunjukkan adanya gugus silanol dan siloksan pada semua material yang membuktikan bahwa semua jenis material alam tersebut merupakan material ekonomis yang kaya akan silika. Sementara itu profil fisisorpsi nitrogen memberikan informasi bahwa modifikasi pori oleh surfaktan hanya berhasil pada ampas tebu. Morfologi bahan alam yang dimodifikasi dan tidak dimodifikasi serta komposisi kimia dari partikel ditunjukkan oleh SEM-EDX.

Abstract: In this research, activated carbon from mangosteen peel has been synthesized using sulfuric acid as an activator. The adsorption performance of the activated carbon was optimized using malachite green dye as absorbate. Malachite green dye waste is a toxic and non-biodegradable material that damages the environment. Optimization of adsorption processes was carried out using Response Surface Methodology (RSM) with a Box-Behnken Design (BBD). The synthesized activated carbon was characterized using FTIR and SEM instruments. The FTIR spectra confirmed the presence of a sulfonate group (-SOH) in the activated carbon, indicating that the activation process using sulfuric acid was successful. SEM characterization shows that activated carbon has porous morphology. Optimization was carried out for three adsorption parameters, namely contact time (20, 60, and 120 min), adsorbent mass (0.005, 0 …

Abstract: High-purity CaO cubic crystallites extracted from limestone exhibited excellent activity as base catalysts for waste cooking oil (WCO) conversion into biodiesel. Saponin from Sapindus rarak extract acted as a surfactant in CaO extraction and transformation into well-defined cubic microcrystallites. The application of saponin from Sapindus rarak extract as a surfactant for CaO production results in a high level of CaO purity and particle size reduction compared to directly calcined limestone (CaO–MgO). The catalytic activity was evaluated on CaO from hydrothermal and co-precipitation synthesis, MgO and CaO–MgO derived from limestone, giving hydrothermal CaO catalysts enhanced biodiesel yield. Optimization of transesterification conditions using Box Behnken Design response surface methodology achieved 92.40% biodiesel yield at 65 °C, 3 h reaction time and when using 5% of CaO catalysts.

Abstract: This study demonstrates the preparation of SiO2/ZnO core–shell nanoparticles with controllable shell size and their optical properties. A facile ultrasonication method was utilized to prepare the core–shell particles in the absence of surfactant materials. The synthesis duration was 75% shorter than that required for the common sol–gel method, which favours its potential applicability in the future for mass production. Tetraethyl orthosilicate (TEOS) was used as the silica source, while the core material was prepared using zinc acetate dihydrate. The outer shell size could easily be controlled by changing the molar ratio of silica from 0.25 to 1.00. The experimental results show that increasing the silica ratio was effective in suppressing the self-agglomeration of ZnO and, further, in obtaining agglomeration-free particles. The investigation of the photoluminescence (PL) properties of nanometre-sized ZnO revealed several …

Abstract: Coconut shell waste pollutes the environment and affects public health. Converting coconut shell waste to pyrolytic oil (liquid smoke) with antimicrobial properties using microwave-assisted pyrolysis and activated charcoal as an absorbent is a promising solution. The purpose of this study is to investigate the process factors involved in the manufacture of coconut shell pyrolytic oil (liquid smoke) using microwave-assisted pyrolysis, to identify the chemical components in coconut shell pyrolytic oil, and to optimize the process factors using a face-centered central composite design (FCCD). This study further used coconut shells of various sizes (1–3 mm) and employed microwave-assisted pyrolysis with different power levels (300–600 W) and pyrolysis times (5–30 min). The results revealed that the pyrolytic oil (liquid smoke) yield increased as the time and microwave power increased but decreased as the size of the materials decreased. The optimum yield obtained was 34.6% at the following conditions: power of 593.6 W, material size of 2.9 mm, and heating time of 28.5 min. The analysis of the components of the volatile compounds in the pyrolytic oil (liquid smoke) product obtained from gas chromatography-mass spectrometry (GC–MS) analysis identified a total of 14 chemical components in coconut shell pyrolytic oil (liquid smoke) at 300 W, 15 compounds at 450 W, and only 5 components at 600 W. Among these compounds, phenol, dimethoxy phenol, guaiacol, hydroxyanisole, and methoxyphenol were found to have the highest concentrations. The outcomes of this study offer valuable contributions to the development of pyrolytic oil (liquid smoke …
