Abstract

Abstract—Fire accidents, due to the leakage of LPG gasses, should be avoided; therefore a systsem that can anticipate the accident is necessary. A system consisting of two sensors and three actuators is designed. MQ5 sensor served as a gas sensor to detect gas concentration of 200 – 10000 ppm. LM35 sensor served as a temperature sensor in range of -55–140. Output system consisted of a buzzer and two fans. System  measurement is performed by modeling a cube for three conditions. The results show that the system created using fuzzy logic control can work on three conditions: 45 ppm is detected at 30.49 (no leakage gas), 70 ppm is detected by increasing temperature up to 31.49 (no leakage gas), leakage gas of 1200 ppm caused the decreased of the temperature to 28.13.

Abstract

Unit Commitment (UC) is a problem to schedule generating units in a power system economically meeting the requirements of load demand and spinning reserve. Up to now several methods have been applied to solve this problem. Among those methods Lagrange Relaxation (LR) seems to be the most suitable one. However, this method may suffer from numerical convergence problem. This paper proposes a new method for solving UC problem. The proposed method uses Evolutionary Programming (EP) to update Lagrange multipliers and improves the performance of LR method. Simulation results show that the proposed method can provide a better solution compared with another methods.

Abstract

Commonly, the current scholarship selection process has different targets and various criteria for its prospective scholarship recipients. This causes the decision-making process for scholarship selection to be complex, whereas in the general scholarship selection is time-limited. The solution that can be done is to use a DSS (Decision Support System) to improve consistency and speed up decision-making. The available methods for making a DSS used in this study are the Analytical Hierarchy Process, TOPSIS, and the second model using a deep learning approach. The performance of the DSS will then be evaluated using a Confusion Matrix to determine the cost level of each DSS and analyze the strengths and weaknesses of each DSS. The DSS model with the AHP-TOPSIS approach has been successfully created, with the accuracy performance for introducing data on merit, bidikmisi, and independent scholarship schemes are 56.72%, 65.21%, and 95.87%, respectively. While the DSS model with a deep learning approach has been successfully created with accuracy performance of 71.93%, 100%, and 100%, respectively. There are considerable differences between these two approaches. This may be due to the weighting process in the AHP approach which cannot be carried out with precision.

Abstract

Abstrak – Pemanfaatan energi listrik sebagai upaya menciptakan green energy memerlukan suatu tindakan yang mendukung produksi energi yang efisien dengan menggunakan satu atau lebih energi alternatif yang dapat digabungkan menjadi sumber energi terdistribusi. Permasalahan pokok permintaan sumber energi yang semakin meningkat adalah keandalan sistem dan kualitas daya. Kualitas daya berkaitan dengan pengurangan nilai rugi-rugi daya listrik, berkurangnya nilai jatuh tegangan serta kontinuitas penyaluran energi listrik yang baik. Penambahan distributed generation (DG) pada sistem eksisting dinilai mampu mengurangi permasalahan kualitas daya dan meningkatkan keandalan sistem. Penelitian ini membahas optimasi penempatan DG dengan menggunakan metode Cat Swarm Optimization dan Krill Herd Algorithm. Optimasi dilakukan dengan menginjeksi DG pada sistem eksisting. Dari proses optimasi dengan CSO diperoleh penurunan rugi daya sebesar 0,2 % sedangkan dengan KHA diperoleh penurunan 29,5 %. Perbaikan profil tegangan dengan metode KHA dinilai lebih baik dari CSO dengan nilai diatas 0,99 p.u sedangkan CSO 0,96 p.u. Penelitian ini mengindikasikan bahwa metode KHA lebih baik daripada metode CSO.Kata Kunci — Distributed Generation, Cat Swarm Optimization, Krill Herd Algorithm.

Abstract

ABSTRAKPemanfaatan sinar matahari dapat digunakan untuk banyak hal, salah satunya adalah sebagai sumber energiterbarukan. Hal ini dikarenakan sinar matahari merupakan sumber daya alam yang tidak akan pernah habismeskipun digunakan terus menerus. Namun, dikarenakan salah satu permasalahan pada pemanfaatan sistem PVadalah energi listrik yang dihasilkan terbilang rendah maka diperlukan metode yang dapat digunakan untukmeningkatkan efisiensi panel surya sehingga saat terjadi perubahan radiasi matahari panel surya tetap bekerjasecara maksimal. Sebagai upaya untuk mengoptimalkan kerja panel surya, perlu Maximum Power PointTracking (MPPT) yang dapat menentukan titik daya maksimal panel surya dengan melacak daya maksimumsebuah panel surya sehingga didapatkan efisiensi maksimum dalam berbagai kondisi suhu dan radiasi. Banyaksekali macam algoritma yang dapat digunakan pada sistem MPPT, beberapa dari algoritma tersebut yaituIncremental Conductance dan Particle Swarm Optimization. Algortima Incremental Conductance dipilih padasimulasi ini karena dapat menentukan titik MPP dan otomatis berhenti pada operating point. Dibandingkandengan algoritma lain, algoritma Incremental Conductance dinilai lebih baik dalam menyesuaikan nilai radiasiyang ditangkap oleh panel surya. Pada simulasi ini juga ditambahkan sebuah konverter Buck-Boost yangbertujuan menaikkan dan menurunkan nilai tegangan secara otomatis sehingga dapat memaksimalkan kerja darikeluaran panel surya.Kata Kunci—Panel Surya, Maximum Power Point Tracking (MPPT), Incremental Conductance, ParticleSwarm Optimization.ABSTRACTUtilization of sunlight can be used for many things, one of which is as a source of renewable energy. This isbecause sunlight is a natural resource that will never run out even if it is used continuously. However, becauseone of the problems in using PV systems is that the electrical energy produced is relatively low, a method thatcan be used to increase the efficiency of solar panels is needed so that when there is a change in radiation, thesolar panels will still work optimally. In an effort to optimize the work of solar panels, Maximum Power PointTracking (MPPT) is needed which can determine the maximum point of solar panels by tracking the maximumpower of a solar panel so as to obtain maximum efficiency in various temperature and radiation conditions.There are many kinds of algorithms that can be used in MPPT systems, some of them are IncrementalConductance and Particle Swarm Optimization. The Incremental Conductance algorithm was chosen in thissimulation because it can determine the MPP point and automatically stops at the operating point. Compared toother algorithms, the Incremental Conductance algorithm is considered better in adjusting the radiation valuecaptured by solar panels. In this simulation, a Buck-Boost converter is also added which aims to increase anddecrease the voltage value automatically so that it can maximize the work of the solar panel output.Keywords—Solar Panel, Maximum Power Point Tracking (MPPT), Incremental Conductance, ParticleSwarm Optimization.

Abstract

Pembangkit listrik tenaga surya pada umumnya tidak dapat menghasilkan daya maksimal sendiri. Karakteristik tegangan fotovoltaik (PV) umumnya mengikuti tegangan baterai atau beban yang terhubung langsung ke PV. Secara umum, tidak semua bagian modul PV menerima penyinaran atau intensitas cahaya yang seragam, sehingga produksi daya tidak optimal dan menyebabkan kasus multi-puncak. Sistem Maximum Power Point Tracking (MPPT) diperlukan untuk mengoptimalkan produksi listrik PV. Namun dalam banyak metode masih ditemukan beberapa kasus terjebak pada puncak lokal dan waktu konvergensi yang lama. Makalah ini mengkaji dan membandingkan kinerja dari dua metode pelacakan, yaitu Ant Colony Optimization (ACO) dan Particle Swarm Optimization (PSO). Hasil percobaan menunjukkan bahwa algoritma ACO memberikan efisiensi rata-rata keseluruhan yang lebih baik daripada PSO,
