Abstract

Pada perkembangan telekomunikasi yang semakin berkembang pesat kebutuhan akan energi listrik juga semakin tinggi, untuk itu perlu digunakan energi alternatif untuk menutupi kebutuhan energi. Energi alternatif dapat memanfaatkan energi yang terdapat di bumi salah satunya yaitu gelombang elektromagnetik bebas dengan menggunakan sistem RF (Radio Frequency) energy harvesting. Salah satu komponen penting pada sistem RF (Radio Frequency) energy harvesting adalah antena. Pada penelitian ini dirancang antena mikrostrip array patch segiempat frekuensi 2100 MHz yang terdiri dari atas 4 susunan. Dari hasil pengukuran antena didapat nilai VSWR dan return loss yang terbaik sebesar 1,07 dan -29,25 dB pada frekuensi 2170 MHz. Tegangan keluaran dari antena mikrostrip yang diimplementasikan pada sistem RF energy harvesting adalah sebesar 17 mV untuk pengukuran daerah kota Medan, yaitu di Laboratorium Sistem Komunikasi Radio, 29 mV untuk pengukuran daerah kota Medan di Jalan Abdul Hakim dan 33 mV untuk pengukuran di Plaza Medan Fair. Dari implementasi yang telah dilakukan dapat diambil kesimpulan tegangan yang dipanen di dalam ruangan lebih kecil dibandingkan di luar ruangan.

Abstract

The purpose of this research is to ascertain whether or not the Wijaya Kusuma Clinic's pharmaceutical services correlate with the level of pleasure its BPJS patients report. The data for this study was collected using a quantitative survey method. Outpatients who participated in BPJS Kesehatan at the Wijaya Kusuma Clinic in Tangerang were asked to fill out questionnaires using Google Forms. All patients receiving BPJS as outpatients made up the study population. We used a combination of the non-probability sampling technique and the purposive selection type to select 328 participants for the study. We processed the data using Ms. Excel 2010 and IBM SPSS Statistics version 29. The study's results revealed that the average age of BPJS patients treated in January 2024 was 26-55 years, with a majority of women at 62.5% and male patients at 37.5%. The patient satisfaction survey revealed that 2.1% of respondents were less satisfied, 43.0% were quite happy, 35.4% were satisfied, and 19.5% were delighted. Therefore, we can conclude that a significant proportion of patient satisfaction respondents fell into the "quite satisfied" category. There is a significant association between the pharmaceutical service variable and the patient satisfaction variable, as indicated by the significance value of 0.001 < 0.05, as determined by the Spearman rank test. With a level of 0.877, it is pretty powerful. The satisfaction of BPJS patients at the clinic is positively correlated with pharmaceutical treatments.

Abstract

This study was conducted to understand how service quality is influenced by responsiveness, responsibility, physical evidence, empathy, and reliability for customer satisfaction. These studies collected data using the questionnaire method and surveyed 30 consumers with experience using online taxi services in Medan City. Data analysis was done using a multiple regression method using SPSS software version 25. Two factors, namely responsiveness and satisfaction, can increase satisfaction. At the same time, it is impossible to improve consumer satisfaction in the other three dimensions of service quality: responsible, physically tested, and empathetic. This research is classified as explanatory research, which aims to elucidate, outline, and offer empirical data or a comprehensive understanding of the impact of the independent variable on the dependent variable defined in this study. The study's population comprises all users of online motorcycle taxi services in Medan. The findings indicate that service quality dimensions, specifically responsiveness and reliability, impact customer satisfaction among online motorcycle taxi users in Medan. In contrast, the aspects of service quality related to guarantees, fictitious evidence, and empathy do not significantly affect customer satisfaction for online motorcycle taxi services in Medan City.

Abstract

The North Sumatra Regional Tax and Levy Management Agency oversees the management of taxes related to motor vehicles and watercraft, the tax for underground water extraction and utilization, the vehicle name transfer duty, and various other revenue streams. It also acts as a coordinator within the regional revenue sector. Research methods can be understood as a systematic approach to gathering reliable data intended to be discovered, enhanced, and verified, allowing for better comprehension and resolution of issues within the business sector. According to the findings of this research, it is evident that Compensation has a significant impact on Employee Performance at the Regional Tax and Levy Management Agency. In the realm of Compensation, an incentive structure connects pay with individual performance. Workers are rewarded through Compensation for their performance rather than their length of service or the total hours they have worked. Based on the data analysis and collection outcomes, Compensation has a significant simultaneous impact on Employee Performance at the Regional Tax and Levy Management Agency. The training partially impacts employees' performance at the Regional Tax and Levy Management Agency. The performance of employees does have a significant partial effect on their overall performance at the Regional Tax and Levy Management Agency.

Abstract

Local rice originates from the Bulungan region of North Kalimantan. Generally, this rice plant is cultivated by the community and divided into two parts, namely mountain or field rice and paddy fields. Differences and similarities in morphological characters in rice cultivars can be distinguished through characterization. Morphological characterization needs to be done to identify specific characters that appear directly, especially characters related to the growth and development of rice plants that can increase the potential for rice yields. Morphological characterization analysis is used to determine the distance and kinship between rice cultivars. This study aims to determine the differences in morphological characters and kinship relationships between 6 local rice cultivars in several areas of Bulungan Regency, namely three types of rice originating from peso villages such as leto Yukon, amai sampan, and anak Leto, while three varieties are types of rice originating from Tanjung Selor. The research was conducted at the Green House of the Faculty of Agriculture, University of Kaltara. The research method used is a descriptive qualitative method, and the data was analyzed using SPSS pc 23.0 software with a scoring form that forms a cluster and produces a dendrogram. The results showed that several local rice cultivars have similarities in several morphological characteristics, such as plant age (HSS), plant height (cm), stem color, leaf blade color, leaf ear color, and leaf tongue color. The similarity coefficient formed is 1,000, and 2 groups (clusters) are formed with close kinship relationships.

Abstract

The development of electric vehicles is one of the government's objectives to save energy and reduce air pollution. The technology for electric vehicles, mainly for personal transportation, involves replacing conventional combustion engines with electric motors. Electric vehicles' advantage lies in eliminating fuel consumption, resulting in nearly zero emissions. To determine the type of electric vehicles that meet the needs of Indonesian society, this study employs the Quality Function Deployment (QFD) method. The research surveyed 40 respondents in the Jabodetabek area to assess their responses to electric vehicle technology in Indonesia. The QFD matrix analysis revealed the priority customer requirements, which include after-sales service availability at every authorized dealer (ATPM), particularly for spare parts and mechanical support, to facilitate vehicle maintenance. The ideal price for electric vehicles is under 300 million IDR. They should have a passenger capacity of seven people and serve multiple functions as family cars, work vehicles, and commercial vehicles. The desired range on a full battery charge is 300 to 500 km, and features such as air conditioning (AC), radio, MP3 players, and comfortable seating are essential. The required motor power ranges from 30kWh to 50kWh.Currently, electric vehicles marketed by several ATPMs in Indonesia still require further development to align with the needs of Indonesian society, ensuring their acceptance in the domestic automotive market.
