Abstract

Well-regulated DC bus voltage is the important point to guarantee the power demand in hybrid vehicle applications. Voltage regulation can be achieved with control method that build switching signal on DC-DC converter. This paper describes design and small scale experimental results of bus voltage regulation control of the DC-DC bidirectional converter with battery and supercapacitor as energy source. The control system consists of two control loops, the outer loop that get DC bus voltage feedback using PI anti-windup back calculation control method. This outer loop will generate a reference current for the inner loop that implement hysteresis control. The inner control loop will compare that reference curent with the source current obtained from the current sensor. Simulation and experimental results show that bus voltage is well-regulated under the load changes with 1% voltage ripple.

Abstract

Cell imbalance has always happened in the series-connected battery. Series-connected battery needs to be balanced to maintain capacity and maximize the batteries lifespan. Cell balancing helps to dispart energy equally among battery cells. For active cell balancing, the use of a DC-DC converter module for cell balancing is quite common to achieve high efficiency, reliability, and high power density converter. This paper describes the implementation of a LiFePO4 battery charger based on the DC-DC converter module used for cell balancing application. A constant current-constant voltage (CC-CV) controller for the charger, which is a general charging method applied to the LiFePO4 battery, is presented for preventing overcharging when considering the nonlinear property of a LiFePO4 battery. The prototype is made up with an input voltage of 43V to 110V and the maximum output voltage of 3.75V, allowing to charge a LiFePO4 cell battery and balancing the battery pack with many cells from 15 to 30 cells. The goal is to have a LiFePO4 battery charger with an approximate power of 40W and the maximum output current of 10A. Experimental results on a 160AH LiFePO4 battery for some state of charge (SoC) shows that the maximum battery voltage has been limited at 3.77 volt and maximum charging current could reach up to 10.64 A. The results show that the charger can maintain battery voltage at the maximum reference voltage and avoid the LiFePO4 battery from overcharging.

Abstract

Cell imbalance can cause negative effects such as early stopping of the battery charging and discharging process which can reduce its capacity. In the previous active balancing research, the energy used for the balancing process was taken from the cell or battery pack, resulting in drop of electric vehicle driving range. In this paper, a cell charger based battery balancing system is proposed with a reduction in the number of switches. The use of a cell charger aims to increase the usable energy of the battery pack, since the energy used for the balancing process is taken directly from the grid. The use of fewer switches aims to reduce the cost and space used on the battery management system (BMS) hardware. The charger used for the balancing process has a maximum current of 3 A and a maximum voltage of 3.65 V while the number of switches used is n+5 for n batteries. A 15S1P 200 Ah LiFePO4 battery pack consists of 15 cells used for testing purpose. The test results show that the time needed to equalize the 15 cell battery voltage reaches 6 hours from the difference between the highest and lowest battery cell voltages of 145.1 mV to 15.1 mV.

Abstract

This study intends to examine three elements: first, how students care about the environment; second, the function of geography education in creating environmental awareness in students; and third, how sociocultural, psychological, and demographic factors affect students' spiritual intelligence. A sample of 79 students from SMP YPI “45” Bekasi participated in this survey. Through the use of questionnaires, data collection procedures were used, and SPSS software was used to analyze the results. Students' assessment of the geography instructor's ability to integrate current environmental issues into their lessons, as well as the student's socio-economic origins and involvement in environmental groups, all have an impact on the student's environmental caring character. An area of interest of study is how socio-economic and cultural features and Demographics affect the ecoliteracy of students and how geography education contributes to the development of their ecoliteracy as a result.

Abstract

Communication patterns are defined as forms or patterns of relationship between two or more people in the process of sending and receiving in the right way so that the message in question can be understood by the communicant (KTH members). The Forest Farmer Group is a group of farmers who work on gardens or forest land owned by Perhutani. Effective communication within the Forest Farmers Group (KTH) II Kampung Citiis is crucial. However, farmers' ignorance about effective communication patterns is a major obstacle. Therefore, the priority issue is counseling and training with an effective communication pattern system between the Chair of KTH II and members of KTH II Kampung Citiis, which requires a deep understanding of the need for interpersonal communication in agriculture as well as strategies to overcome the ignorance of forest farmers so that messages related to agriculture can be conveyed and understood well by all KTH members. The most effective communication is communication when it is able to change someone's attitude, opinion or behavior dialogically and this can be done between the Extension Officer and the farmers, not depending on how big the quantity is but how big the quality is. Based on the problems that have been identified with partners, there is an agreement to determine priority problems for which immediate solutions will be sought, with the aim of Agricultural Extension and Training which prioritizes how to plant horticulture, coffee and protect forests. Apart from that, efforts are explained to find out the differences and similarities between good and correct planting techniques. There are three activity methods used by the team, namely the directing method, mentoring method and facilitation. The research method in this study uses a descriptive-explanatory research type, namely describing and explaining efforts to find out the differences and similarities in good and correct planting techniques, including fertilization, treatment and plant maintenance, while the data analysis techniques used in this research include interview transcripts, data reduction, analysis, data interpretation and triangulation.

Abstract

This research analyzes the documentary “Dirty Vote” using Ferdinand de Saussure's semiotic analysis to identify and interpret the signs and symbols used in the film. The film, which was released ahead of the 2024 General Election, raises the issue of fraud in Indonesia's electoral process. The semiotic analysis shows that the signs in the film represent complex political strategies and manipulations, including the use of the chess game symbol to illustrate careful planning and the term "pork barrel politics" to indicate the use of public funds for private interests. In addition, the “4-finger salute” symbol indicates the merging of certain political forces. The film "Dirty Vote" succeeded in raising public awareness of the importance of transparency and fairness in the electoral process, as well as motivating people's active participation in election monitoring.
