Abstract

Abstract—Bali province is one of 34 provinces of Indonesia and according to General Plan of National Energy it was expected to develop around 110 MW solar PV by 2025. Economically, Bali is considered as the center of Indonesian tourism industry. A wide range of accommodations have been developed to support the industry including villa. In this paper, potential of rooftop PV of villas in Bali is presented. Rooftop PV capacity was designed with objective to meet 23% of the villa’s energy consumption. Two villas in the southern of Bali were taken as examples. Energy audit was conducted to study the energy usage of both villas. Based on the design objective, 13,7 kWp grid-connected PV was proposed for each of the villa. With these results, it was projected that all villas in Bali could add solar PV capacity around 34,8 MWp which canpotentialy generateannual energy of 54.741 MWh. Investment analysis and environmental performance are also included on this paper. The results presented here will help provincial and district governments of Bali to get insight into potential of tourism sector to support PV development and subsequentlyto developappropriate policies and regulations to accelerate the uptake of rooftop PV in Bali.

Abstract

One of practical example of CVRPTW is delivery. Important factors in delivery are cost, speed, service and consistency. In order for these factors to be met optimally, the capacity and time windows must be considered. Capacity affects service and consistency, so the right route must be choosen with the shortest distance and the right capacity. Time windows affects on the speed and costs so that the delivery must be carried out according specified time and company operating hours. This research purpose to produce delivery routes that consider capacity and delivery time. There are two steps in calculation, which is clustering and searching of optimal delivery route. The clustering step uses a polar angle and the optimal route searching uses the nearest neighbour and the tabu search. The test show that the delivery route generated by the system can make efficiency distance of 12.18%, time of 5.54% and capacity of 1.27% and cost of 12.18%.

Abstract

In this project, a tool that can explain phenomena involving the photoelectric effect at laboratory scales is being developed. The purpose of this tool is to help users understand that the photoelectric effect, which causes electrons to move from a source of a negative voltage to a source of positive voltage, is not affected by light intensity but rather by a light source's frequency and wavelength. A photodiode is employed in the creation of this device as a light sensor, and when exposed to light, it moves electrons from the cathode to the anode, causing an electric current to flow. The voltage is delivered to the cathode, which is where the electrons leave, to calculate the stopping voltage. A graph showing the connection between the ADC value and the sensor output voltage is produced from the ongoing data gathering. Our results show that each color spectrum has a distinct voltage supplied to the photodiode leg (cathode). Additionally, the output voltage measured for each distinct wavelength was decreased the lower the photodiode's light intensity was.

Abstract

Augmented Reality technology applied in the world of education can make the learning process more effective and more efficient. This study built an augmented reality application by applying the marker based tracking method which was then applied to the industrial instrumentation practicum course at the Faculty of Agricultural Technology, Udayana University. This aims to make practicum more effective and efficient. The resulting application is then tested using 2 tests, namely usability testing using the Usability method with a Likert scale and comparison testing using the Paired Sample T-test method. Usability testing aims to determine an assessment of the usability level of the application. In this test, we get a reusability value of 73.5 from a scale of 0-100. These results can be interpreted that this application has a good usability value. Comparative testing using the Paired Sample T-test method aims to obtain information on the extent of the comparison of the understanding of each respondent before and after the application of augmented reality in industrial instrumentation courses. In this test, the Sig. (2-tailed) of 0,000 which is still below the threshold of the Paired Sample T-test, which is 0.05. So this research concludes that there is a real difference between the results before and after the respondents used the application. This study concludes that the functionality of using this application can be considered to replace the visit of industrial instrumentation practicum courses so that the implementation of practicum becomes more effective and efficient.

Abstract

Pengoperasian beban-beban nonlinear dapat menimbulkan distorsi harmonisa dalam bentuk gelombang tegangan dan arus yang mengakibatkan kondisi sistem kelistrikan tidak normal. Blue Point Bay Villa & Spa memiliki kandungan harmonisa yang tidak sesuai dengan standar IEEE 519-1992. Kandungan THD (Total Harmonics Distortion) arus yang berlebih dapat menyebabkan kualitas daya sistem menjadi lebih buruk, sehingga menyebabkan faktor daya sistem menjadi lebih rendah. Filter aktif shunt berbasis inverter yang bertujuan untuk meredam harmonisa yang muncul. Dalam penelitian ini dilakukan simulasi penggunaan filter aktif menggunakan sofware simulink MATLAB, pengelompokkan jenis beban nonlinear, perhitungan daya aktif (P) dan arus beban (IL), simulasi pada sistem sebelum dan sesudah penggunaan filter aktif, analisis daya distorsi (D), analisis THD hasil simulasi sesuai dengan IEEE 519-1992 yang ditentukan dan analisis penempatan filter aktif shunt yang tepat untuk menekan distorsi daya. Hasil analisis menunjukkan pemasangan filter aktif menyebabkan kandungan THD arus dan tegangan telah sesuai dengan IEEE 519-1992 yang ditentukan. Daya distorsi harmonisa pada sistem mengalami penurunan dan terjadi peningkatan faktor daya mendekati unity power factor pada feeder. Penempatan filter aktif shunt yang baik untuk menurunkan THD dan distorsi daya yaitu pada SDP 2 MDP 2 yaitu 7.551,23 VA.
