Abstract

Heating System, Ventilanting and Air Conditioning (HVAC) or air conditioning systemsbecome one of the needs in high rise buildings in order to increase comfort in the room,differences in the level of comfort of each individual makes the HVAC system changes in loadpatterns that can result in wasteful use of electrical energy. This study aims to determine thesavings in the use of electrical energy with the use of DDC in the HVAC system at the Langhamhotel. DDC can regulate HVAC system supporting devices such as cooling towers, condenserwater pumps, chilled water pumps and chillers that aim to reduce the performance of the chillersso that energy savings are obtained. By using 2 work operation methods, the results of thecalculation of energy use obtained at the side of the chiller Langham hotel, with manualoperation without the use of DDC obtained a total consumption cost of IDR 3,409,290 andautomatic work operations using DDC obtained a total consumption cost of IDR 2,601,990 sothat it is obtained saving percentage of 24%.

Abstract

Analysis of the EDF (Electric Ducted Fan) thrust motor test and the determination of the takeoff system on the ATmega 328-based rocket vehicle is a prototype design of a thrust test tool that is used to measure the thrust output of a 70 mm EDF motor used as a vehicle propulsion engine. EDF rockets as well as a prototype rocket takeoff system that serves as a takeoff indicator using the data from the EDF thrust motor test as a reference for rocket liftoff. The data measured in the EDF motor thrust test are, among others, thrust data detected using a load cell sensor, RPM data (EDF motor rotation) detected using an infrared proximity sensor, PWM (Pulse Wide Modulation) output data from the mapping input potentiometer. and a 16x2 LCD module with I2C used to display test data. The thrust test data used on the prototype of the rocket takeoff system are RPM and PWM data with indicators ready to take off using green LEDs. The prototype of the take-off system of the rocket vehicle is based on the ratio between the thrust of the EDF motor and the rocket's weight (thrust to weight ratio) of ?1. The results of the research when testing the thrust on the EDF motor with a 6 blades propeller obtained maximum RPM and thrust data of 73619 RPM and 695.3 g, for testing on the EDF motor with a 12 blades propeller obtained the maximum RPM and thrust data of 65861 RPM and 696.2 g RPM, where all these data is obtained when 100% PWM output from Arduino to ESC (Electric Speed Controller). Thrust to weight ratio produced on each EDF motor with 6 blades and 12 blades propellers is 1,202 and 1,189. Takeoff system uses PWM input reference to brushless motor ESC at 100% ratio

Abstract

Rancang bangun sistem tracking panel surya berbasis mikrokontroler arduino merupakan sebuah alat yang digunakan untuk mengikuti arah pergerakkan matahari setiap jamnya, mulai dari terbit hingga terbenam. Sistem tracking panel surya ini akan mendeteksi setting waktu yang diinput oleh RTC (Real Time Clock). Pembuatan sistem ini dibagi menjadi dua bagian yaitu pertama adalah perancangan perangkat keras (hardware) yang terdiri dari perancangan perangkat elektronika dan perancangan perangkat mekanik. Kedua adalah perancangan perangkat lunak (software). Pemrograman sistem tracking menggunakan software arduino. Panel surya digerakkan dengan menggunakan motor servo yang bergerak sesuai input waktu yang diberikan oleh RTC. Pergerakkan panel surya diatur setiap jam dengan sudut yang telah diuji, sehingga posisi panel surya selalu tegak lurus dengan arah datangnya cahaya matahari. Hasil dari rancang bangun sistem tracking panel surya berbasis mikrokontroler arduino menunjukkan bahwa alat yang dirancang sudah dapat mengikuti pergerakkan matahari berdasarkan waktu.

Abstract

The Bali Provincial Information and Statistics Communication Service requires a Trouble Ticket application to report and document internet problems that exist in the offices of the Bali Provincial government. In addition to having functions as needed, the Trouble Ticket application must also pay attention to UI and UX. The method that has been widely used to create UI designs is the Golden Ratio. In addition to the Golden Ratio, there is a Ratio that has not been developed in the field of UI design, the Ratio is the Supergolden Ratio. Supergolden Ratio is the ratio obtained from the Ratio Limit Narayana Sequence which is worth 1.4656. In this study, a Trouble Ticket application design will be designed using the Supergolden Ratio method. The Trouble Ticket and UEQ application designs are given to users to determine the user experience (UX) when using the Trouble Ticket application design. The UEQ results show that the user experience of the application design that is designed using the Supergolden Ratio method produces positive results. Aspects of attractiveness, clarity, efficiency, accuracy, and simulation showed excellent results, while the novelty aspect showed good results.

Abstract

Dye-sensitized solar cell (DSSC) is one of the potential candidates for the next generation solar cells. One of the most attractive features of the DSSC is the low production costs. The utilization of natural dyes is a new area for investigation due to their unique capability to absorb photons from natural sunlight or artificial light and convert it into electric current. The purpose of this study is to determine the potential of natural dye from red dragon fruit waste as a dye sensitizer. Red dragon fruit peel is initially extracted using methanol and the solution absorption spectra then is characterized using UV-Vis spectrophotometer. The absorption spectra is measured within a wavelength range of 400-800 nm. The characterization results show that the maximum absorption spectrum is at a wavelength of 446 nm. The natural dye solution then is used to immerse Fluorine Tin Oxide (FTO) coated with titanium dioxide (TiO2). The glass FTO is immersed in the dye solution for 24 hours. DSSC then is prepared by sandwiching the working electrode and counter electrode. An electrolyte solution is used to fill the interface between the two electrodes. The current and voltage (I-V) characteristics of DSSC is finally measured using amperemeter and voltmeter. The results indicated that the natural dye from the peel of red dragon fruit has potential as a dye sensitizer. Further research is still required to improve the performance of the DSSC.
