Evaluation of Smart Mobility Indicators in Responding COVID-19 Pandemic in Indonesia
Get PDFThe COVID-19 outbreak cuts the number of trips and people’s movement during the day. Not only because of the community’s awareness for the disease transmission but also because of the enforcement from the government to apply the mobility policy. This changing trip behavior is predicted to happen throughout the time of pandemic and post-pandemic. On the contrary, when mobility is decreasing, the role of ICT in community activities is increasing. This condition leads to an interesting question for the smart city, especially the smart mobility concept, whether the smart mobility concept has been properly addressed and responded to the pandemic and post-pandemic era or not. This paper aims to explore how far smart mobility planning has been applied by local governments in Indonesia, especially in response to community activity during the pandemic era. Our approach in this paper is a qualitative study in evaluating online local government planning documents as our main data. We choose the study cases in three cities that got high tier ranks in the smart city awards in 2019 (based on Rating Kota Cerdas Indonesia/Indonesia’s Smart Cities Rating), which are Semarang, Samarinda, Magelang. We review literature on smart mobility indicators and those smart mobility indicators used in planning documents. Then, we evaluate the relevance of those indicators to the condition of pandemic and post pandemic era. We found that smart mobility indicators have not been received much concern as the main aspect of smart city in Indonesia

Reliability Analysis of Passenger Ship Structure Conversion in Bali Straits
Get PDFLCT conversion passenger ships have been widely operated in the waters of the Bali Strait. Ship operations in the Bali Strait result in repeated loads on the structure. Repeated loading produces vertical and horizontal bending moments that act randomly due to waves. Based on this, it is necessary to analyze the structure of the ship. The purpose of this study was to analyze the reliability value of the ship structure operating in undulating waters. Wave analysis is performed using the spectral method to determine the value of the load acting on the ship, while the reliability calculation uses the Mean Value First Order Second Moment (MVFOSM) method to determine the reliability value. The analysis was carried out on a full load and an empty load. The value of the reliability of the structure at full load is 0.913615 and at empty load is 0.88948

Get PDFSetiap tahun, prevalensi penyakit kanker leher rahim di dunia semakin meningkat. Kanker serviks dapat terjadi akibat infeksi Human Papillomavirus (HPV). Saat ini, penargetan penghambatan onkoprotein E6 cenderung dipilih karena lebih aman dan lebih baik sebagai agen terapeutik kanker serviks. Selain itu, E6 juga termasuk virus krusial yang menginduksi kanker serviks melalui inaktivasi protein p53 sehingga diperlukan material yang efektif untuk menghambat kinerja onkogen E6. Hidrazon merupakan senyawa basa Schiff yang memiliki gugus azometin (-NHN=CR-). Gugus azometin inilah yang berperan dalam berbagai bioaktivitas, termasuk antivirus dan antikanker. Pada penelitian ini, hidrazon berasal dari turunan 2-tiohidantoin dan hidrazida. Senyawa 2-tiohidantoin termasuk kelompok heterosiklik yang memainkan peran penting dalam kimia obat seperti antikonvulsan, antibakteri, antidiabetik, antivirus dan antikanker. Dengan demikian, senyawa ini dapat menjadi agen alternatif pengobatan kanker serviks. Sebelum dilakukan sintesis material tersebut, perlu dilakukan analisis bioaktivitas menggunakan komputasi. Kajian metode in-silico meliputi pembuatan struktur menggunakan Avogadro, optimasi geometri molekul menggunakan Gaussian 16, serta hasil interaksi ligan-protein (RMSD, KI, Binding Affinity, ADME, Binding Pocket, dan Drugability score) menggunakan Autodock Tools, LigPlot, SwissADME, PLIP Tools, dan Protein Plus. Hasil penelitian menunjukkan bahwa senyawa hidrazon yang berasal dari turunan 2-tiohidantoin dan hidrazida berpotensi menghambat protein E6 dan dapat digunakan sebagai obat oral
ANALYSIS OF MECHANICAL PROPERTIES OF CuZn35 WITH HEAT TREATMENT USING MACHINE LEARNING & TAGUCHI OPTIMIZATION
Get PDFYellow brass is an alternative material for cartridge application. Heat treatment conducts on yellow brass to improve mechanical properties to fulfill the cartridge requirement. The main objective of this paper is to analyze the optimal parameters on the effect of heating temperature, holding time, and cooling medium on the tensile strength and hardness of yellow brass material as an alternative to CuZn30 replacement bullet casing material. Taguchi optimization and machine learning were carried out to evaluate several factors with a minimum number of tests using an orthogonal array experimental layout. The process parameters that will be optimized are furnace cooling media, water, and air. Annealing temperatures are 300, 400, and 500oC, and holding times are 60, 90, and 120 minutes. The results of the Taguchi method show that the parameter that has the most influence on the value of hardness and tensile strength is the heating temperature with a percent contribution of 85.8278% to hardness and 99.115% to tensile strength. On the machine learning results, the XG Boost model validation shows the MAE, RMSE, and R square values respectively 6.12; 8.23; 0.43 for the hardness response variable. The tensile strength response variable shows a value of 4.81; 7.76; and 0.49. Metrics from the validation show that a small sample using the Taguchi design can produce a good enough model to predict response
THE EFFECT OF ACETIC ANHYDRIDE-TREATED SILICON CARBIDE ON MORPHOLOGICAL AND MECHANICAL PROPERTIES OF EPOXY/CARBON FIBER/SILICONE CARBIDE COMPOSITES
Get PDFEpoxy is widely applied in various fields because of its excellent properties. The filler is needed to enhance the properties of the epoxy composite. The pretreatment of fillers can improve the mechanical properties of the composites. The objective of this study was to determine the influence of acetic anhydride (Ac2O)-treated silicon carbide (SiC) on morphological and mechanical properties of epoxy/carbon fiber/SiC composites. The SiC was immersed in Ac2O with the concentration of 0, 4, 8, 12, and 16 wt% for 5 hours at room temperature. The epoxy/carbon fiber/SiC composites were made using the hand lay-up method. The morphology, tensile strength, and flexural strength of the composite were investigated. The SEM images indicated that the Ac2O affects the surface of SiC particles. The higher Ac2O concentration provided the higher tensile and flexural strength of the composite. The 16% Ac2O-treated SiC increased the composite’s tensile strength (86 MPa) and flexural strength (65 MPa). The treated SiC using Ac2O is suitable to improve the mechanical properties of epoxy/carbon fiber/SiC composite
Evaluating the Success of E-Invoice Implementation at a State-Owned Enterprise Using DeLone & McLean IS Success Model
Get PDFE-Invoice considered as one of the most implemented financial information systems these recent years. E-Invoice had grown from a system that brings convenience, into a part of the strategy to fulfill corporate expectation. However, it’s uncertain whether E-Invoice implementation indeed successfully brings proven benefits into the company business. Therefore, the aim of this study is to identify the indicators that affect the success of E-Invoice implementation in a particular state-owned company, based upon DeLone & McLean IS Success Model. In terms of evaluation, previous research regarding E-Invoice mostly discussed about the key factors that influence the adoption of E-Invoice. Lesser literatures purposed at studying the success of the implementation, related to the system performance. According to DeLone & McLean IS Success Model, there are six variables used as basic measurement, namely information quality, system quality, service quality, user satisfaction, intention to use, and net benefits. Following that, a set of structured questionnaire arranged and distributed to 34 users of an E-Invoice system provided by a state-owned enterprise headquartered in Rembang, Indonesia, including vendors and employees. The data then will be processed using Partial Least Square (PLS) method. The result showed that Information Quality and System Quality gave significant impact to User Satisfaction and User Satisfaction gave significant impact to Net Benefits. Meanwhile, Service Quality is not proven empirically to gave significant impact to both User Satisfaction and Intention to Use
Prototype Portable Electrical Resistance Tomography
Get PDFTomography is a way to describe something non-destructively. Some types of Tomography are Electrical Resistance Tomography (ERT), Electrical Impedance Tomography (EIT), and Electrical Capacitance Tomography (ECT). This study aims to combine the ECT and ERT systems. The combination uses the ERT technique (Borehole method) and develops until it can be used like ECT. This research conducts three significant stages (design making, designed realization, and examination). The examination is carried out by simulation and experimental measurement. The simulation result is compared to the result of the experimental measurement. The result shows that both have the same patterns, but it has the amplitude of voltage difference pattern. It is because the resistivity result affects the measured voltage difference result. The higher the resistivity result of the medium, the smaller the measured voltage difference.Tomography is a way to describe something non-destructively.
