Pages: 161 - 168
Abstract: Water is a daily necessity that is often stored in water tanks. Water tanks are often placed at a height to take advantage of the force of gravity for optimal flow. Good water quality is necessary for the fulfillment of daily needs. The high position of the water tank is difficult for the user to find out the quality and remaining volume. Poor water quality such as experiencing turbidity can have a bad impact. So we need a system that can detect turbidity and water volume and can inform users remotely. The technology that can be used is the internet of things. The system built will monitor the turbidity and volume of the user's water tank, as well as control the pump in the form of turning on and off. The sensors used are LDR sensors to detect turbidity and ultrasonic sensors to detect water levels which are then calculated into water volume. The process of interaction between users and the system using a bot from instant messaging Telegram. The test results of the system have been able to monitor turbidity and water volume and control the water pump through interaction with users via the Telegram bot. The test results show the average speed of the whole system process is 1.48s.

Abstract: Indonesia is located along the equator so that it has a huge potential for solar energy, but it has not been able to be utilized optimally to reduce the use of fossil energy that is not environmentally friendly. In order to increase the use of new and renewable energy by 23% in 2025 where the target for the utilization of solar energy is 6.5 GW, the Government through the National Energy Council issued a policy to encourage each region to accelerate the utilization of solar energy in accordance with the mandate of the General National Energy Plan which requires the use of a minimum of 30% of the roofs of government buildings for the use of solar PV rooftop. The Denpasar City Government in implementing the Bali Provincial Energy General Plan can implement solar PV rooftop system at the Denpasar Mayor's Office Building as a pilot project for government buildings in Denpasar City. From the results of technical studies that have been carried out, the Denpasar Mayor's Office Building has a total roof area of ''1,732.14 m2. However, based on the Minister of Energy and Mineral Resources No. 49/2018, in this study designed solar PV rooftop with a capacity of 112.5 kWp. Solar PV rooftop simulation with PVSyst produces an average annual performance potential of 81.6% with an annual energy production of 175 kWh. Solar PV rooftop which is designed can save the use of PLN's electrical energy by 72.12% in a year. The results of the design are then tested economically using the NPV, IRR, BCR, PI and PP methods. NPV is positive at discount rates of 6%, 10%, and 15%. The IRR test is worth 20.12%, the BCR test is 14.57, the PI test is 7.31 and the PP test states that this investment requires a period of 3.4 years to return the initial capital. Based on the technical and economic analysis, the design of solar PV rooftop on the roof of the Denpasar Mayor's Office is very feasible because it is able to produce electrical energy that can save significant use of PLN's electrical energy and meet the investment eligibility criteria.

Pages: 201 - 208
Abstract: The problem with waste in Jember Regency is that waste management has not been maximized. The abundant availability of combustible waste can be used as RDF as waste to energy. This study analyzed the potential RDF and the feasibility of constructing a PLTSa at TPA Pakusari using the life cycle cost method. The electricity cost is calculated by LCoE, obtained by dividing the total present value life cycle cost of the total energy generated. The potential of RDF from the results of the water content and ash content produced does not require the RDF quality standards of several countries. In contrast, the volatile content test and the calorific value of the waste after treatment have required the RDF quality standards. The level of GHG emissions produced is 1,8 tCO2. The results of the economic analysis show that the LCC value during a lifetime is Rp. 75.903.806.400. The feasibility of the Pakusari PLTSa development plan is declared feasible with a PBP value of 13 years. The NPV value with an interest rate of 8,5% is Rp. 22.065.398.707,03, and the IRR value is 14,35%. In the profitability index and net B/C criteria, the project is declared feasible with a value of 2,3.

Abstract: — The DC motors often experiences rotational speed instability due to disturbance. To overcome this, PID control can be applied to stabilize the speed. PID control is a combination of proportional, integral, and derivative controls. To achieve good performance, it is necessary to tune these parameters using several methods, such as genetic algorithm. The genetic algorithm works by forming a population of individuals that potentially can produce optimal solutions judged by the fitness value. Several parameters are used in genetic algorithms such as population size, number of generations, crossover probability, and mutation probability. This study aims to analyze the genetic algorithm method for tuning PID control parameters in controlling the rotational speed of the DC motor. The results obtained genetic algorithm parameters with population size and the number of generations of 70, crossover probability of 0.9, mutation probability of 0.4 and a fitness value of 6.261e+18. PID parameters with value of Kp = 9.4429; Ki = 19.3255 and Kd = 0.45602 and system response with rise time value of 0.1212 s, settling time of 0.2562 s, overshoot of 0.0366% and steady-state error of 0.1739%. With these PID parameters, the DC motor can follow the setpoint at constant and changing load values.

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.

Pages: 53 - 62
Abstract: Multilevel inverter (MLI) is one type of inverter that has a multilevel output voltage. Although its better than conventional inverters, the MLIs operating at low frequency still contains low-order harmonics at the output voltage and current which have a negative impact on electrical system. To overcome these problems, Many researchers have developed various control and modulation techniques on inverters to reduce harmonics and minimize switching losses with the aim of optimizing inverter’s efficiency. Selective harmonic elimination pulse-width modulation (SHEPWM) is the most optimal control of all methods that have been developed to remove low-order harmonics from the inverter output voltage. However, there are challenges in the MLIs analysis process using SHEPWM because solving these equations is difficult. Bio-inspired intelligent algorithms (BIAs) is used to solve this problem. This paper describes in full a review of various studies that have been carried out previously related to the operating principle of nine types of BIA and their application in reducing harmonics. The conclusions has been made on the basis of information extracted from the literatures. All important information in this paper regarding harmonic reduction in MLI will help future research to design efficient power conversion systems. Keywords— Bio-inspired algorithm, harmonics, multilevel inverter, optimization, selective harmonic elimination.

Koloni Bakteri
Authors: Ni Ketut Novia Nilasari, Yoga Divayana, Rukmi Sari Hartati
Pages: 71 - 76
Abstract: — The exact estimation of the number of colonies or Colony Forming Units (CFUs) is frequently used in microbiology research, particularly in the field of bacteria. The number of colonies that develop per gram or milliliter of sample is estimated by multiplying the number of plates, the dilution factor, and the volume used [1]. Counting the number of bacterial colonies can be used to determine a bacterium's growth rate. The cup count method is commonly used to accomplish this manually. An instrument called a colony counter can help with colony counting utilizing the cup count method. This technology works by using a pen connected to a counter to mark the colonies that have been counted. However, because the colony size is tiny and the number of colonies counted is huge, this can lead to inaccuracies, and the same difficulties can happen with manual colony computations. Digital image processing technology has been extensively developed for use in a variety of fields. Researchers had previously undertaken a similar study that attempted to count bacterial colonies and had a 94 percent accuracy rate, but some colonies were not spotted because they were filtered during preprocessing, so they looked into it further.

Pages: 143 - 148
Abstract: DVC has the characteristics of lighter encoder performance by transferring the efficiency of the field of motion to the decoder. The characteristics of DVC are similar to FRUC which is a technique to improve the quality of video display from the decoder side by inserting interpolated frames. In this study, multi-resolution bilateral motion estimation based on pyramid wavelets is proposed by comparing the order of wavelets contained in the daubechies wavelet. The parameters compared in this study are PSNR and the computational complexity of the proposed method to improve the quality of the video reconstruction from the decoder side. This study shows that the use of the daubechies wavelet order in the proposed method can obtain sufficient category of PSNR values of db6 with a value of 27.37 dB for video images with moving background characteristics and moving objects, good categories of db7 and db10 with a value of 34.8 dB and 32.06 dB for video images with fixed background characteristics and moving objects, and video images with moving background characteristics and fixed objects. The selection of the wavelet order on the daubechies wavelet can be adjusted to the characteristics of the video image that will be used.

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.
