Abstract

Cryptocurrencies have great potential to be adopted in Indonesia as an alternative to investing. One of the cryptocurrencies that investors or traders are interested in is Solana. Fluctuating price. movements make cryptocurrency investments considered. speculative so the risks. faced are very high. With this, we need a system or model that can help investors or traders to predict prices so that investors or traders have material for consideration in making decisions. The results of the descriptive analysis can be seen that in the period from April 10, 2020 to May 30, 2022, Solana's daily closing price movement fluctuates. The Support Vector Regression model obtained for Solana's daily closing price data, namely the Linear kernel with cost parameter C = 1000, obtained an. accuracy of 97.44% and MAPE 9.93 while for the Radial Basis Function. (RBF) kernel with cost parameter C = 1000 an .gamma = 0.1 obtained an accuracy of 87.76% with a MAPE value of 8.14. It can be concluded that through parameter tuning, the model formed has an accuracy value and the. best MAPE is to use a linear kernel with a cost parameter of C = 1000.

Abstract

A solar panel is a series of photovoltaic cells that converts sunlight into electrical energy. The solar panel can work optimally during daytime because the output power depends on the light intensity, temperature and load contained in the solar panel. Therefore an algorithm of Maximum Power Point Tracker (MPPT) is required as a storage control in order to obtain the maximum output power using secant method. This method is one of the methods used to find the root value of an equation, i.e. by taking sampling of an equation that will be used to assess the equation root by applying the slope estimate differentiation. The result of this method was used to set up the duty cycle utilizing DC-DC buck converter. Duty cycle was set at 50% with a duration of 0.25 seconds, functioned to regulate the output voltage of the solar panel in order to be in maximum position which does not exceed 14 V. At the peak position the tracking was slightly constrained by reading output voltage from the solar panel to calculate the new value. Thus, the output of the solar panel would follow the output of solar panel in order to be at the maximum point

Abstract

In banking activities, customers datas that is managed and stored by the bank, including the management of bank products such as savings accounts and time deposits. However, the recording of customer data at the ALMASOEM Sharia People's Financing Bank has not been computerized so that managing customer data takes a long time, causing the service to be less effective and efficient. The purpose of this study is to build a website-based information system for opening a savings and time deposit account at BPRS ALMASOEM. With this information system, it is easier for customer service to manage and serve customers quickly and precisely. This design uses a prototype method where users and developers play an active role in developing the system, while for information data collection by field observations, interviews, literature studies and systems approach. Website built using Laravel framework, PHP as programming language and MySQL database

Abstract

Brooding is a period after hatching of eggs which aims to provide a comfortable environment for chicks to support optimal growth. Newly hatched chicks are not yet able to regulate their body temperature optimally. For this reason, it is necessary to use lights so that the temperature of the cage remains comfortable. Controlling light intensity is generally not maximized because the light produced is only bright and dark. This study aims to design a light control system using fuzzy logic with a range of values between light and dark. In this study, a prototype was made that utilized fuzzy logic using an Arduino mega microcontroller and a dht11 sensor to detect temperature and humidity with an incandescent lamp output. The brightness of the light is regulated by a dimmer driven by a servo motor. Fans are used to lower the temperature. Research shows that the prototype can control the light intensity according to the temperature and humidity conditions in the cage. The prototype used five chicks for 14 days, where it was found that the chicks could develop well with increased body weight, growth of feathers on the wings and tail, and good appetite, and no death occurred.

Abstract

The rapid advancement of technology is reflected in improvements to equipment that facilitate human work, such as the parking system employing RFID (Radio Frequency Identification). The RFID technology is able to record incoming and outgoing data for short-distance data transfer. The intended audience for this work's development is junior or senior high school students. Finally, students are expected to be able to develop effective parking solutions with little cost and expertise. Two registered cards and one unregistered card are used to test this tool, with ten tests being run on each card. Some of the tests that have been carried out include the efficiency of RFID and ultrasonic sensors in reading registered cards and detecting heading vehicles, as well as the use of RFID obstacles to test the extent to which the frequencies in RFID can operate, even when they are still obstructed by other objects. The test results show that the system could work properly, and read with the right level of precision with 0.3 seconds an average delay. Additionally, the resulting RFID reader can still detect registered cards at a distance of 1.5 cm even with a border thickness of up to 2.0 mm.

Abstract

The Independent Power Plant (IPP) of the Oelpuah Solar Power Plant (SPP) in Kupang Regency has been operating since November 2015 with a 5 MWp. However, the maximum power produced has not yet reached optimal power production, only in the 3,000 - 4,000 kW range. Therefore, a study is needed to identify and analyze the decrease in output power. The measurements in December showed that solar radiation, temperature, and equipment damage significantly affected the decrease in output power by 35.7%. Then, based on the simulation results, the output power produced by the array when tilted at 15° and azimuth 0° is 4,000 kW with an E grid of 9,111 MWh/year. This power will increase to 4,100 kW with an E grid of 9,113 MWh/yr when tilt is 14° and azimuth is -5°. Conversely, a decrease in output power can occur due to changes in tilt and azimuth positions by 0.10%. The other influencing factors are internal factors such as 1.68% inverter losses and 3% solar panel quality losses; meanwhile, in terms of external factors such as solar panel losses due to radiation levels (0.16%), temperature (13.5%), GHI (2.40%), and damaged equipment (25%).

Abstract

This works takes samples and case studies in the Amarasi area, Kec. TTS, Prov. NTT; because there is still little literature and research conducted in rural areas, especially in the dry land of Semi-arid areas. Therefore, this study analyzes the measurement of the performance of the 4G LTE network, both voice and data communication, carried out in two different conditions, namely outdoor and indoor based on four parameters, namely RSRP, RSRQ, SNR and Throughput. The percentage of the RSRQ category is very good 32%, and bad 1%. The percentage of SNR category is very good 19%, and bad 1%. The average for throughput is 15.81 Mbps download and 18.41 Mbps upload which is good for Kotabes, Tunbaun and Nonbes villages. The measurement results in indoor conditions, the percentage of the RSRP category is very good 4%, and bad 24%. The percentage of SNR category is very good 23%, and bad 1%. The average throughput is 8.79 Mbps download and 11.57 Mbps upload; namely in the villages of Teunbaun, Tunbaun and Aprein. The results of the analysis show that the 4G LTE network has good and promising performance.

Abstract

Internet of Things (IoT) is the interconnection of several devices that have specific tasks such as sensing and control. The services in the system can be in the form of one device - one service, many devices - one service, one device -many services, and many devices - many services. A communication protocol is agreed upon by the devices in the IoT system to ensure the success of data transactions. These protocols include MQTT, HTTP, AMQP, XMPP, Web Shocket, and COAP. This study compares the performance of the COAP and HTTP protocols in consideration of the number of transactions and energy consumption. The scenario used is to send RSSI data and battery level. The scenarios also use two modes of transmission power:14dBm and 20dBm. The results show that the COAP protocol is 25 times more efficient than the HTTP protocol for a 20dBm transmit power scenario, while for a transmit power of 14dBm COAP is 61 times
