Abstract

Baterai alkalin merupakan salah satu jenis baterai yang didesain untuk sekali pakai. Akibatnya limbah baterai tersebut banyak. Untuk mengurangi dampak limbah baterai dirasa perlu adanya konservasi baterai yaitu dengan memperpanjanag usia pakainya, sehingga menunda baterai tersebut menjadi limbah. Cara mudahnya adalah mengisi ulang baterai agar dapat digunakan kembali. Walaupun baterai alkaline merupakan baterai yang sekali pakai, namun dari karakteristik reaksi elektrokimianya terlihat bahwa reaksi kimia tersebut dapat dibalik sehingga terdapat kemungkinan bahwa baterai dapat diisi ulang. Beberapa batasan dalam pengisian ulang diantaranya menyangkut kondisi baterai, strategi pengisian ulang, batas jumlah siklus pengisian dan kapasitas baterai saat diisi ulang. Penelitian ini membahas prosedur konservasi baterai alkalin bekas untuk meningkatkan umur pakai yang sekaligus mengurangi dampak negatif limbah baterai terhadap lingkungan. Hasil experimen menunjukkan bahwa metode gabungan tegangan konstan dan arus kontan adalah yang paling cepat dan aman dalam mengisi ulang batere alkaline, dan rata-rata batere alkaline dapat diisi ulang hingga 8 kali.

Abstract

Electrical Vehicle (EV) has been developing since the mid-18th century and reached its peak at the end of the 18th century. Dwindling fuel reserves and environmental damage caused by exhaust emissions from millions of fossil-fuel vehicles are the driving factors for the development of electric cars, technological developments in the battery sector have also contributed to the development of electric cars. One of the important components in an electric car is the battery which will provide resources to the system, so determining the capacity and knowing the performance of the battery used is very important. To find out the battery performance, the model can be made using MATLAB/SIMULINK. The model built consists of electric (DC motor, control and battery) and mechanical (transmission, wheels, brakes and body) parts. Of the models made for speeds of 35, 40, and 45 kmph on level ground, the distances that can be covered are 2,292, 2,597, and 2,899 m, while the remaining battery capacity (SoC, %) is 92.93%, 91.16%, and 89.17%. This is proportional to the distance traveled which also proves that the model made is appropriate. Uphill roads affect the use of battery capacity, the greater the angle of incline, the greater the battery capacity used.

Abstract

Kepyar Village, located in Purwantoro District, Wonogiri Regency, possesses significant potential for the development of natural tourism due to its lush and pristine environment. However, despite its scenic beauty, the village remains relatively underpromoted, resulting in limited tourist visits, predominantly from nearby areas. This study explores the use of TikTok as a promotional tool to enhance the visibility of Kepyar Village as a tourist destination. By utilizing TikTok for destination branding, the village aims to attract a wider audience, thereby benefiting the local economy and community. The initiative is expected to raise broader public awareness about Kepyar Village’s tourism potential, contributing not only to its reputation as a tourist village but also providing an economic avenue for residents to improve their livelihoods.

Abstract

The capacity strengthening program for electric vehicle conversion workshops at SMK Karya Nugraha Boyolali was implemented through a synergistic collaboration model between universities, vocational schools, and industry. This study employed a qualitative descriptive approach with a case study method to evaluate the effectiveness of the six-month program. The findings revealed a significant improvement in participants’ technical competencies, as evidenced by the increase in pre-test and post-test scores, as well as the successful development of a solar photovoltaic (PV)-based electric vehicle charging station prototype. Beyond technical achievements, the program also strengthened multi-stakeholder collaboration and fostered the creation of a micro-scale clean energy ecosystem within the school environment. These results demonstrate that practice-based vocational training combined with strategic collaboration can make a substantial contribution to achieving the Sustainable Development Goals (SDGs), particularly clean energy (SDG 7), industry innovation (SDG 9), and climate change mitigation (SDG 13).

Abstract

Biological cells has natural characteristic to isolate subtances between outside and inside cell by using its membranes. By applying pulsed electric field, membrane pores can be formed that facilitates the introduction of small foreign materials into cells. The success of this technique can be determined by observation of conductivity changes. The equivalent conductance can be measured but the unhomogeneous electric field results unhomogeneous conductance. The aim of this research is to compute conductivity distribution on a specific biological tissue (e.g. mammalian muscle tissue) that being electrically pulsed. The tissue is modeled as conductive medium due to its conductivity dominant. The medium as a system of electrocondusive, modeling of this system leads to get a model in the form of partial different equation problems. A finite element method is used as a tool to solve the problem. The final simulation result are graphical presentations showing the conductance. It is also shown that the intensity of the field is higher in the location near electrode and smaller in remote location. Then, electrical conductivity, derived from electric field exposure is then can be computed. It is shown that needle electrodes exibit inhomogeneous conductivity distribution. A large increase of conductivity occurs surrounding both electrodes and much smaller increase on other location. A larger conductivity change means more number and size of pores are produced. In practical aspect, the result can be further developed for designing in-vivo pulsed electric field applications
