Abstract

Eligibility for Study Programs and Higher Education is determined based on the accreditation process. The accreditation criteria refer to the National Higher Education Standards. Nine standards that must be complete with documents in the accreditation process. The process of preparing form instruments is still done manually causing problems in the process of completing form instruments, because they have to recap a lot of data and require more time to retrieve and process the required data. To simplify the preparation of the form instrument, a data warehouse scheme and service-middleware built to collect the data needed in the preparation of the form instrument. The data warehouse schema design will use Kimball's Nine-Steps approach. Meanwhile, application development will use the Agile approach. The results of this research are in the form of data warehouse schema modeling in the Agile development process for the needs of study program accreditation forms.

Abstract

Abstract—VTOL-plane is a hybrid vehicle that combines a fixed-wing vehicle and a rotary-wing vehicle with the advantages of good endurance and good maneuverability. Combining these two types of UAVs requires a control system capable of stabilizing the shift from fixed-wing to rotary-wing mode or vice versa. Attitude disorientation occurs in the form of a decrease in height due to overshoot. therefore, a mode or control many input parameters. The Linear Quadratic Regulator (LQR) control method is one of the control methods capable of producing minimum errors and capable of many input parameters. The LQR control system produces a control response with a rise time according to the needs. The LQR control meets the specifications of the VTOL-plane vehicle requirements to handle minimum errors. Attitude disorientation occurs due to overshoot, as well as handling of the control system which can only handle a small amount of input and output on the VTOL-plane vehicle. Keyword - Control, LQR, Overshoot, UAV.

Abstract

DC-DC converter are required in industrial application to convert a fixed DC voltage into a variable DC voltage. This article focuses on the cuk converter topology which can operate in buck-boost mode which is regulated through the duty cycle pulse width modulation setting and controlled by the dsPIC33EP512MU810 microcontroller by applying the Proportional-Integral (PI) digital closed loop current control method. Using PI control method is considered capable of producing optimal performance and increasing the response time that occurs. The frequency given by the generator signal is used as a reference signal to inject current into the inductor (L1). The current sensor module acts as a measuring device and a reader of the actual current value that appears through the load. The difference between the reference current value and the actual value will produce an error signal value so that it becomes the comparison value of the current sensor results with the PI control method. Simulation results on PSIM, modeling analysis, device implementation and hardware testing graphs in the laboratory have been carried out to prove the design parameters and proposed methods can work as intended.

Abstract

Peternakan merupakan kegiatan pengembangbiakkan dan pemeliharaan hewan yang dapat dilakukan dengan sistem kandang maupun sistem lepas. Sistem peternakan lepas masih banyak dijumpai di wilayah Nusa Tenggara dan sebagian wilayah di Bali. Peternakan jenis ini sulit dipantau sehingga rentan pencurian. Selain kemungkinan pencurian, sistem pengembalaan hewan ternak seperti ini memiliki banyak resiko lain, salah satunya adalah kehilangan ternak baik itu karena tersesat ataupun terjebak di suatu tempat. Maka dari itu perlu dikembangkan suatu alat pelacak yang mampu memonitoring keberadaan hewan ternak tersebut. Penelitian ini bertujuan untuk mengimplementasikan Internet of Things (IoT) guna memonitoring hewan ternak atau peliharaan dengan memakai GPS, NodeMCU ESP8266, Firebase dan Kodular. Data berupa nilai latitude dan longitude yang didapat oleh modul GPS akan dikirimkan ke Firebase melalui jaringan WiFi. Data tersebut kemudian ditampilkan pada aplikasi Kodular dalam bentuk koordinat latitude, longitude, dan marker pada maps. Selain itu, alat tracking yang dapat dikalungkan pada leher hewan ini dilengkapai dengan lampu LED yang bertujuan untuk memantau posisi hewan ternak pada malam hari sehingga posisi hewan dapat terlihat ketika kondisi gelap.

Abstract

In this paper, the contribution for finding the tilt and azimuth angle, location, and shift optimum with shading analysis method using PVSyst software has been done. The PV module capacity is 20 kWp that and integrated as canopy in the crosswalk between LABTEK V and LABTEK VI, ITB campus, Bandung. Coodinate from the location of PV modules is 6,89 LS dan 107,61 LT (- 6,89 oS, 107,61 oE). Fixed tilt was used for the PV modules orientation. The buildings and trees around the PV module cause shading effect in the PV modules, therefore, to maximize PV performance additional optimization and shading analysis have to be carried out. Performance achieved tilt angle 11o and azimuth 0o with effective global irradiation 1160,1 kWh/m2/year and energy array 21,75 MWh/tahun. After tilt optimization, shift and array optimization was added for improve the PV modul performance. In the added the shift and array optimization scenarios, the effective global irradiation has improved 72 kWh/m2/year and 14,9 kWh/m2/year respectively and the energy array has improved 1,26 MWh/year and 0,25 MWh/year.

Abstract

Forecasting is the process of estimating a future value using data from the past or data from the present as a reference. Forecasting is a critical component of an organization's short- and long-term planning as a reference for management decision making. Identifying the data pattern in the time series data utilized is a crucial step in identifying the best forecasting approach for the data pattern. The Gray Prediction Model is a forecasting technique that can be used with partial data or a little amount of data. The Grey-Markov forecasting approach may be used to make very accurate forecasts using Udayana University education acceptance data, which is limited, with only five historical data and data patterns classed as horizontal data patterns with modest fluctuations.

Abstract

Pemanfaatan sumber daya alam dan energi semakin hari semakin meningkat, salah satunya adalah penggunaan gas bumi sebagai bahan bakar baik untuk kebutuhan rumah tangga maupun industri. Aspek safety dalam penggunaan gas ini haruslah diperhatikan karena kebocoran gas dapat memicu terjadinya kebakaran. Maka dari itu dibutuhkan alat yang dapat mendeteksi dan menotifikasi kebocoran gas sedini mungkin. Penelitian ini mengusulkan alat pendeteksi kebocoran gas berbasis Internet of Things (IoT) menggunakan NodeMCU ESP8266 sebagai mikrokontroler. Sistem pendeteksian ini menggunakan sensor MQ-2 sebagai pendeteksi kadar gas dan flame sensor sebagai pendeteksi sinar ultraviolet sebagai indikasi adanya api. Output yang dihasilkan berupa pesan notifikasi dari Telegram Bot yang dikirimkan melalui NodeMCU. Dalam hal ini, buzzer dan LED akan memberikan sinyal jika sensor MQ-2 mendeteksi kadar gas di atas 500 ADC, lalu NodeMCU akan mengirim perintah kepada Telegram Bot untuk mengirimkan pesan notifikasi secara realtime. Disamping itu, kadar gas yang terdeteksi juga ditampilkan pada layar LCD 16x2. Hasil percobaan menunjukkan bahwa jarak ideal untuk mendeteksi gas adalah di bawah 6 cm, sedangkan api di bawah 20 cm dengan waktu respon sensor 2 detik. Dengan alat ini diharapkan dapat meminimalisir resiko kebakaran akibat kebocoran gas. Kata Kunci— kebakaran, kebocoran gas, NodeMCU, Telegram
