- Optimasi Pengoperasian Pembangkit Listrik Untuk Minimalisasi Emisi Gas
Buang Menggunakan Metode Quadratic Constrained Programming
Authors: Patria Julianto, Risna Febrianti
Pages: 1 - 8
Abstract: Pertumbuhan jumlah penduduk serta kemajuan teknologi saat ini menyebabkan kebutuhan energi listrik selalu meningkat setiap waktu, baik untuk skala listrik rumah tangga, komersil maupun industri. Untuk memenuhi kebutuhan energi listrik tersebut sebagian besar dilakukan menggunakan pembangkit listrik termal. Pembangkit termal beroperasi dengan bahan bakar yang umumnya berupa bahan bakar fosil seperti gas, minyak dan batu bara sehingga akan menghasilkan emisi gas buang yang berbahaya seperti nitrogen oksida (NOx), sulfur dioksida (SO2), dan karbon dioksida (CO2). Emisi gas buang tersebut berdampak buruk pada lingkungan sekitar serta akan berkontribusi signifikan terhadap emisi gas rumah kaca dan perubahan iklim global. Penelitian ini mempunyai tujuan untuk meminimalisasi emisi gas buang yang dihasilkan pembangkit melalui optimasi emission dispatch. Fungsi objektif pada emission dispatch merupakan emisi gas buang minimal yang terdiri dari variabel keluaran daya pembangkit dan koefisien emisi masing-masing pembangkit listrik yang beroperasi. Pada penelitian ini emission dispatch diselesaikan menggunakan metode quadratic constrained programming (QCP) dan telah berhasil diujicoba dengan menggunakan data sistem IEEE-30 bus dan sistem Jawa-Bali 500 kV.

Pages: 9 - 18
Abstract: The transportation service system requires improvements to evolve into a smart and more efficient system. Passengers waiting at bus stops can create long queues, causing a lack of available shuttle bus capacity when arriving at the bus stop. This work proposes a genetic algorithm model to minimize passenger waiting time and schedule shuttle buses to stops with high capacity. The Genetic Algorithm works by searching for the optimal value to result in optimal waiting time by providing calling shuttle bus. After the method reaches the optimal solution, the simulation result will provide a minimum waiting time. In case studies of simulated design at either campus in Central Java, Indonesia. This method provides a simulated system shuttle bus on scheduling to raise a challenge in waiting time efficiency and passenger accumulation at campus transportation. The case studies of the application on passenger waiting time showcase the model's ability to improve transportation services in the unscheduled campus area. This system was designed to ensure that it was effective in addressing the transportation challenges faced by students and staff. Use the full potential of bus transportation in the campus area to ensure continuity between stops and city transportation. Therefore, this approach reduces waiting times and schedules to overcome challenges posed by passenger accumulation for structured campus transportation services.

Authors: Muhammad Ali Maskur, Ony Asrarul Qudsi, Indra Ferdiansyah
Pages: 19 - 26
Abstract: Abstract— In general, BLDC motors have a position sensor (hall sensor) in them, where there is a hall sensor, this will provide position information feedback to the observer so that by using the sensored method the motor operation can be carried out properly because the control is perfectly synchronized with the rotor position. This research discusses regulating the speed of a brushless DC motor using a BLDC inverter motor control method, namely six-step commutation. This system uses a modified folding bicycle concept, with the controller coming from a microcontroller integrated with an Android application to monitor measurement data. Tests were carried out partially and integrated the entire system without load and using mechanical loads. The test results in this research are that the three-phase inverter has an error rate of 0.75%, as well as the voltage sensor which has an error rate of 0.49%, and the current sensor with an error rate of 0.994%. The motor speed produced by the inverter will increase as the input voltage increases. The maximum speed that an electric bicycle can reach is 30 km/h. Battery voltage, current and power measurement data is sent in real time to the Android application.

Pages: 49 - 56
Abstract: A tornado is one weather process that arises due to atmospheric instability. A tornado is a strong wind, but not all strong winds are tornadoes. Tornadoes have a short time frequency but can result in no minor disaster because they can blow objects away and uproot trees. Due to the consequences, an early warning system is needed as an anticipation for the community in the affected areas so that it can help the community by warning early on of the occurrence of a tornado. The ANFIS (Adaptive Neuro Fuzzy Inference System) method is used to forecast the event of a tornado, and the parameters used are wind speed, ambient temperature, and ambient humidity. This study will compare the ANFIS method using hybrid and backpropagation algorithms. Using the backpropagation algorithm, an error of 0.42385 was produced during training and testing, and an average error of 136.54 was obtained. When using the hybrid algorithm, the error during training is 2.0781 x 10-5, and the average error during testing is 0.015%.

- IoT Berbasis NodeMCU ESP8266 Sebagai Decision Support System Pengelolaan
Energi Gedung Telkomsel Renon
Authors: Amien Harist Hardiansyah, I Nyoman Satya Kumara, Rukmi Sari Hartati
Pages: 103 - 116
Abstract: The Telkomsel Renon Building serves as the regional telecommunications service office for the Bali and Nusa Tenggara area, covering an area of 5072 m2 with a PLN power capacity of 555 kVA. PT Telkom is committed to reducing energy consumption by implementing ISO 50001 energy management. Despite this, the use of 14 smart meters is still manually conducted, leading to a lack of real-time energy usage information. PLN data indicates an average energy consumption from 2017 to 2023 of 628.271 kWh, with an average annual cost of Rp. 696.915.017. Factors such as electrical equipment, room size, activities within, and building insulation affect the building's energy consumption. Inappropriate activities relative to room capacity can lead to energy wastage. One solution proposed for accurately monitoring energy usage in real-time involves the development of an Internet of Things (IoT) based application using Blynk. IoT is implemented in large meeting rooms with Central Split Duct AC and small meeting rooms with Split Wall AC. Measurement results indicate significantly higher energy consumption in large meeting rooms, reaching 4207,83 kWh, compared to only 467,06 kWh in small meeting rooms for similar activities. Discussions with users of small meeting rooms revealed their comfort and successful achievement of meeting objectives. By utilizing small meeting rooms, energy consumption can be reduced by up to 88.9%. Based on these findings, recommendations for room usage SOPs have been formulated for the Telkomsel Renon Building to realize energy-efficient practices towards green building standards.

Metode Deep Learning
Authors: Moch Deny Triatmaja, Lie Jasa
Pages: 237 - 242
Abstract: SBL (Single Bottom Labeller) machine which was still not precise for placing the bottom label batches of lip cream products. Postal operators must then check one by one to ensure product quality control so that there are bottlenecks. Therefore, this research uses the YOLOv5 deep learning method to solve this problem. The YOLOv5 algorithm uses the idea of regression, making it easier to learn generalizations, target characteristics and solve speed problems. The YOLO algorithm uses a one-stage neural network to complete the localization and classification of detected objects in real time. The core idea of YOLO is to take the entire image as network input and directly return the bounding box position and bounding box class in the output. In YOLO, each bounding box is predicted by the features of the entire image, and each bounding box contains the five predictions and a confidence, which is relative to the grid cell in the middle of the bounding box. The results of research using the YOLOv5 method can classify into three classification categories of bottom label placement, namely accept, reject and no label. In addition to classifying, this study will also send triggers to the controller if the bottom label is said to be rejected and no label to do product sorting to assist QC operators in sorting lip cream production defects.

- LED lights of various colors for comprehending the photoelectric effects
phenomena
Authors: Soni Prayogi, Fitria Silviana
Pages: 243 - 248
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.

Various Topologies for Solar Panel Monitoring
Authors: Dodi Setiabudi, Daris Irfan Atmaja, Dedy Wahyu Herdiyanto, Gamma Aditya Rahardi
Pages: 255 - 264
Abstract: Abstract— Solar panels require performance monitoring when energy shortages occur in the area. Monitoring solar panels requires a detection device to detect solar panels, including the ACS712 current sensor for monitoring the output current of the solar panel, a DC voltage sensor for monitoring battery performance, and a DHT11 temperature sensor for monitoring the temperature of the solar panel storage battery. The WSN technology that can work is ZigBee communication. This ZigBee communication research uses various topology methods, including star, tree, and mesh topologies. Solar panel monitoring tests are carried out indoors and outdoors. The ZigBee communication device used is the XBee S2C device, which operates at a frequency of 2.4 GHz. From a comparison of various topologies, the mesh topology is a topology with good performance because it has the characteristic of choosing a router with the fastest path to reach the coordinator. It is proven by monitoring solar panels with an optimal distance of 80 m, which is carried out from outdoors with an RSSI value of -84 dBm, a throughput of 0.55 kbps, and a delay of 2.77 ms, producing power for 150 minutes with an average current of 0.14 A, voltage of 9.86 V, and temperature of 31.48°C. The number of disturbances and weather conditions greatly affect signal propagation, which can hamper the data transmission process. Throughput fluctuates due to uncertain weather conditions, and delay fluctuates due to a lot of interference from other radio signals.

- Analisis Penentuan Respons Twitter sebagai Media Komunikasi dan Informasi
Pemerintah Berbasis Metode Rabin-Karp
Authors: Luh Ayu Diah Fernita Sari, Nyoman Putra Putra Sastra, Rukmi Sari Hartati
Pages: 265 - 272
Abstract: Social media in this digital era, especially Twitter, has an important role in the interaction between government and society. Given the wide variety of activities within government circles, the task of monitoring and responding to messages is complex and time-consuming. Therefore, this study aims to develop an effective approach in determining the appropriate response from the government to people's tweets. This study proposes using a combination of the Rabin-Karp method to quickly determine relevant responses. The Rabin-Karp method, known for its efficiency in pattern matching, is used to match tweets to a set of tweets that have already been given a response. Furthermore, the Word2Vec technique is used to improve understanding of the meaning of the text. The use of the Rabin-Karp method with the addition of the Word2Vec method shows that the response accuracy rate is 74.55%. The results of this study also show that the lower the K-Gram value, the higher the similarity value, and vice versa. These results are expected to contribute in the context of government that is responsive to societal issues discussed on Twitter.

Abstract: The Development Administration Section is an organization in the field of government in Gianyar Regency which has a work program which is to supervise the realization of the budget for each RAO (Regional Apparatus Organization) and is assisted by using the TEPRA Information System to carrying out a routine evaluation process every month, so it is important for the information system to minimize the risks that may occur. The research process uses two frameworks, namely the COBIT 2019 framework and the NIST 800-30 framework. The use of NIST 800-30 found 12 gaps out of 12 threats with 8 risks being medium and 4 risks being low. Continuing the use of COBIT 2019 resulted in calculating the highest rating value in the first process APO 13 domain with a value of 4.58, a percentage of 91%, Fully category. And the domain with the lowest percentage with a value of 3.00, the percentage is 60%, the Largely category is the second and third process APO 13 domain, DSS 02 domain, first and second process DSS 03 domain and DSS 04 domain. Next, the assessment of maturity levels produces the highest score in BAI 05 domain with a value of 4.27, level value 4 (Quantitative). And the domain with the lowest score with a value of 3.00, the level value 3 (Defined) occurs in the domain DSS 02, DSS03, and DSS 04. Next, the gap level assessment with the highest value occurs in the third process APO 14 domain with a value of 1.92 which is the level of effectiveness in using problem data that does not run smoothly according to system functionality. Based on the results of the research conducted, it is hoped that it will create a developing government and create good governance, so that in the process of developing an information system, the recommendations for improvements that have been suggested can be implemented.

Abstract: Distribution transformers play a crucial role in the distribution network by transforming electrical energy from the source to the customers. This is closely related to issues in the process of distributing electrical energy. According to PLN standards, a transformer is considered overloaded when the load exceeds 80% of its installed capacity. Overloading can lead to increased transformer temperature, potentially damaging the insulation and causing power supply disruptions to consumers. A B&D 50kVA distribution transformer has been installed on pole 17A/U3-30 in the Belibis Street, Wonocatur, Banguntapan, Yogyakarta area. The transformer is currently experiencing a load of 112.5%. In this study, the insertion of an additional transformer is proposed as a solution to reduce the overload percentage and voltage drop. The transformer insertion has already been implemented in the field, and this study aims to analyze its impact by determining the optimal location through simulations. Based on the simulation results using ETAP 12.6.0, the transformer insertion on pole 1/S3-19 in the field can improve the voltage value at the customer end to 0.94 p.u., with a load of 86.6% on the inserted transformer and 35.6% on the existing transformer. However, an optimal location determination is found on pole 18/S3-17 based on the best voltage value at the customer end, which is 0.94 p.u., with the existing transformer operating at 58.1% load and the inserted transformer operating at 65.3% load. The inserted transformer can effectively reduce overload and voltage drop for customers, and by determining the optimal location, it can enhance the efficiency of analyzing load development and voltage values.

Authors: Agus Permana Putra, Gede Sukadarmika, Dewa Made Wiharta
Pages: 305 - 310
Abstract: Monitoring utilization server which refers to the use of server resources such as CPU, memory and storage is important in managing Information Technology (IT) infrastructure by network administrators in an effort to help maximize server performance, identify performance constraints and make decisions to increase efficiency servers. Monitoring is done by checking resource usage one by one on the server to find out which server resources are running. However, the more servers there are, the more time it takes to monitor so that it can interfere with the performance of network administrators. To make it easier for network administrators to monitor, researchers created a resource utilization and visualization model using Prometheus and Graphana which can display server resources without having to check directly on the server you want to monitor. The final result of the research produced a model that can visualize server resources in a dashboard without the need to check the servers one by one so that it helps network administrators work to monitor server resource usage.
