Abstract

A pellet dryer machine is a tool that makes it easy to dry pellets so it doesn't have to require sunlight to dry the pellets. Various methods have also been widely used to control the temperature on the machine. One of the obstacles experienced is controlling the temperature so that it remains stable and has a good response time. In this journal, a pellet drying machine with PID (proportional integral derivative) method will be designed to keep the temperature stable. The temperature that makes the setpoint is 100 degree C. In the design carried out, it is by comparing sistems that are given Proportional control, Proportional and Integral (PI) control and Proportional Derivative (PD) control. For the controller used, it is an Autonics TK4S type controller. In the control, PID tuning will be carried out which will later be carried out variations of each Kp, Ki, and Kd values.

Abstract

Abstract The museum is a place to store historical relics that are very important as evidence that these relics are true. Museums are also a means for a country to show the public about the relics of historical objects which are treasures and must be preserved. Lampung Province State Museum, is one of the museums in Indonesia. One of the relics that must be preserved in this museum is the traditional Lampung cloth which is still there and is a legacy for the people of Lampung. The Lampung Museum has a collection of traditional Lampung fabrics whose safety conditions are still a problem for the Lampung Museum management, where there is a lack of care and it is easy for visitors to touch and change the layout of these items. This can cause damage and changes to the collectible. Therefore, the Passive Infra Red (PIR) sensor-based Security System is a tool designed to maintain the security system of the Lampung Province State Museum object "Ruwa Juwai", by using a PIR sensor which can detect the presence of infrared rays which will be detected by the sensor and then will activate the buzzer and LED as output. The design of the PIR sensor-based security system tool is carried out by observing the infrared sensor detected on the PIR sensor and the output on the security system tool in the form of a buzzer and LED.Keywords Lampung Museum, Security System, Passive Infra Red Sensor

Abstract

Di era kebutuhan akan internet semakin meningkat di masyarakat dan ilmu pengetahuan. Hal ini tidak hanya berdampak positif pada pertumbuhan pengguna, tetapi juga dapat berdampak negatif yang dapat berujung pada pelanggaran penggunaan internet. Oleh karena itu, diperlukan sistem monitoring agar dapat memantau aktivitas yang dilakukan oleh user terhadap perangkat komputer yang digunakan. Sederhananya, seperti mengirim pesan log kepada sistem yang terpusat. RSyslog server adalah sebuah perangkat lunak gratis yang digunakan pada sistem komputer untuk meneruskan pesan log dengan melalui jaringan IP. Pesan log yang telah terekam di RSyslog server kemudian disimpan ke dalam database dengan menggunakan MySQL. Dalam hal ini, MySQL sebagai media penyimpanan yang telah memiliki format penyimpanan pesan log yang direkam oleh RSyslog sehingga memudahkan administrator untuk memantau dan mengelola pesan log yang telah disimpan. Sehingga pengimplementasian artikel ilmiah ini menggunakan metode Network Development life cycle (NDLC) untuk mendapatkan gambaran dari alur perancangan Rsyslog server agar dapat digunakan oleh administrator sistem. Dengan dirancangnya sistem administrator agar dapat memantau pesan log dari komputer lain, dapat memudahkan perawatan komputer dalam satu jaringan dan dapat meminimalisir tindak kejahatan yang dilakukan oleh pengguna komputer.

Abstract

Abstract Transformer oil is very important because it functions as a coolant and also as an insulator. In transformer oil there are dissolved gases that can cause failure of the transformer due to gas failure (fault gas). This research was conducted to determine the condition of transformer oil by analyzing the results of the Dissolved Gas Analysis (DGA) test. The DGA (Dissolved Gas Analysis) test is used to determine the type of failure in a transformer that has been operating for years. The DGA test is carried out by monitoring fault gases such as H2, CH4, CO, CO2, C2H4, C2H6, C2H2, O2, N2 and O2N2 which generally cannot be detected in testing the characteristics of transformer oil. Based on the test results using the Total Dissolve Gas Analysis (TDCG) method condition 1 with the amount of flammable gas 202.845 ppm with the interpretation that the transformer can operate normally. The test results using the Roger's Ratio method on the Power Transformer 1 GI Kotabumi obtained codes 0 0 0. From the combination of the 3 codes above, it shows that the transformer oil is in good condition. The results of the test using the Key Gas method on Power Transformer 1 GI Kotabumi obtained a CO value of 56 percent caused by overheating of cellulose or overheating of solid insulation in the transformer but that value is still far from the threshold Keywords Dissolved Gas Analysis (DGA),Transformer oil, Roger'r ratio method, KeyGas

Abstract

The water turbine must be specially designed according to the calculation of its energy potential, proportional to the height of the falling water and the discharge. This research is conducted to study the solution fluid engine that functions as a pico hydro water turbine, namely a centrifugal blower with a simple construction, operating at low head, small discharge, easy installation and operation and low price. The blower used in this test is a blower that is already on the market with an impeller diameter of 15 cm, inlet size of 2 inches. The test was carried out at a constant head (falling water height) of 5 m. The working principle of the blower is reversed, that is, water from a certain height flows through the rapid pipe and enters the exhaust side of the blower until the water moves the blower and exits through the blower inlet to the draftube. The purpose of this study was to determine the effect of modification of the blades on the increase in efficiency of the picohydro turbine. This study uses an analytical method with testing parameters based on calculating the value of water discharge, water power, torque, turbine mechanical power and turbine efficiency. To increase the power and efficiency of the blower as a turbine, modifications are made to the blower blades. With the modification of the blower blades, the turbine efficiency increases by 10 percents from before the modification.
