Abstract

This is the preliminary finding of a study elaborating the total energy consumption when paratransits in Bandung are altered into electric and the scenario to fulfill it. Therefore, there are lots to be done further concerning result of this initial research, of which will be discussed in another publication. In this paper calculation was done to find out the volume of power needed to fuel electric paratransits in Bandung. Steps carried out include computing total energy consumption for all paratransits, clustering stations from classified routes established by local Department of Transport, and estimating the electricity demand in every clustered station. Data used for this study was acquired from Badan Pusat Statistik Kota Bandung and PT PLN DJA APD Jawa Barat and Banten. A total demand of 61.12 MWh per month will surface to charge the total of 5,521 paratransits from 38 available routes in 15 clustered stations under the assumptions that all paratransits only make 6 return travels per day, operate 30 days per month, and use batteries with 50% State of Charge.

Abstract

This paper describes a feasibility analysis of conventional and retrofitted paratransits, comparing economic performance of conventional paratransit with those using lead acid and lithium batteries. Research object is Dago-Kalapa paratransit in Bandung, West Java, travelling the distance of 11 km in town, under 8 peak hour operation. After calculating the estimated annual cost and benefit; net present value (NPV), payback period (PBP) and internal rate of return (IRR) then were quantified to provide feasibility description of those three paratransits. In addition, a sensitivity analysis regarding discount rate, gasoline price and battery price is given to offer broader sense of factors embraced. It is found that both gasoline and lead acid paratransit have big NPVs with only slight differences, while lithium paratransit has negative NPV. This phenomenon applies to their PBPs and IRRs as well. Only when gasoline costs reaches IDR 15,000 will electric paratransit prevails over conventional one. Thus, it can be inferred that at the moment, paratransit runs with gasoline is still the most cost effective compared to its counterparts. However, starting retrofitting from now is endorsed due to its environmental benefit.

Abstract

Surface roughness and area play important role especially in deposition and reaction of the catalyst in the catalytic converter substrate. The aim of this paper is to show the modification of surface roughness and area of FeCrAl substrate for catalytic converter using ultrasonic method. The method was conducted by agitating the FeCrAl in 10 minutes 35 kHz ultrasonic cleaning bath. The  surface roughness, morphology, and chemical components of FeCrAl catalytic converter substrate after ultrasonic treatment were analyzed using atomic force microscope (AFM) and examined with scanning electron microscope (SEM) in combination with energy dispersive X-ray spectroscopy (EDS). The ultrasonic treatment assisted with Al2O3 powders successfully increased the roughness and surface area of FeCrAl better than SiC powders.

Abstract

Sinergi antara Internet of Things (IoT) dan Electric Vehicle (EV) sudah semakin banyak dilakukan. Sayangnya, belum banyak penelitian yang membahas peran IoT dalam aplikasi EV secara umum. Karena itu, studi ini dilakukan dengan tujuan untuk menambah pustaka di bidang tersebut dengan menjawab dua pertanyaan penelitian berikut: di bidang apa saja IoT dapat diimplementasikan untuk melengkapi EV dan apa saja perkembangan yang telah terjadi di bidang tersebut. Penelitian ini merupakan sebuah reviu yang menggunakan metode penulisan tinjauan naratif. Metode ini diawali dengan penyortiran makalah jurnal dan prosiding dari database Science Direct dan IEEE Xplore melalu proses penyaringan berdasarkan kata kunci, seleksi abstrak, dan makalah lengkap. Seleksi ini menghasilkan 43 tulisan untuk direviu. Hasil yang didapatkan dari proses reviu menunjukkan bahwa topik pengisian daya merupakan hal yang paling banyak diteliti. Topik yang banyak dibahas dalam area pengisian daya adalah penjadwalan dan manajemen energi baik untuk grid maupun baterai. Usaha untuk menjaga privasi dalam semua bentuk transaksi IoT juga mengalami kemajuan yang signifikan. Melihat luasnya area aplikasi IoT dalam bidang EV, dapat disimpulkan bahwa masih banyak objek yang potensial untuk diteliti demi kemajuan IoT-EV ini.

Abstract

Bus listrik merupakan sarana transportasi publik yang jika aplikasinya dapat mencapai kondisi ideal akandapat berfungsi untuk mengurangi kemacetan lalu lintas sekaligus menurunkan level CO2 di udara. Sayangnya adopsi bus listrik di Indonesia belum mencapai tingkat yang ditargetkan. Karena belum banyakstudi yang membahas tentang soal ini, artikel ini bertujuan untuk merekomendasikan strategi yang harusditerapkan untuk mengakselerasi elektrifikasi angkutan masal melalui sebuah tinjauan naratif mini. 26artikel dari jurnal dan prosiding dari database Scopus berhasil dikumpulkan melalui proses penyortiranyang dimulai dari kata kunci, skimming abstrak dan artikel lengkap. Proses review kemudikan dilakukanuntuk mengetahui apa yang dapat dilakukan di Indonesia dalam mempercepat transisi dari bus konvensionalke bus listrik berdasar studi dari implementasi yang dilakukan oleh sejumlah negara tetangga. Hasil minireview ini menunjukkan bahwa dukungan pemerintah merupakan kunci percepatan adopsi bus listrik, disamping pembagian beban di antara pemangku kepentingan di sepanjang value chain dan bentuk modelbisnis yang harus dapat mendukung inovasi. Kata Kunci: adopsi bus listrik, strategi Indonesia, angkutan umum berbahan bakar alternatif, pemangkukepentingan, willingness to pay
