Published: March 2021

Drought is a disaster that has a significant impact on agriculture, economics, health and the environment, and many other aspects of life all including Kabupaten Bandung Barat (KBB), Indonesia. The Regional Disaster Management Agency (BPBD) of KBB shows that in 2018, over 92,780 houses in 47 villages were affected by drought. This study aims to predict which area in KBB will be impacted by drought using Geographical Information System (GIS). Previous studies have shown much evidence that GIS will work, but none were done in Indonesia. We use the Simple Additive Weighting (SAW) method to create the ranking, categorization, and information on potential droughts. The method analyses historical drought impact, rainfall densities, water resources, rivers, and lakes availability, and settlement area. At the end of this study, we successfully categorize 162 villages into 4 categories. Accuracy on the result is also tested using real data from 2018, which resulted in 70.21% accuracy out compared to all 47 villages that were affected in 2018. An increase in accuracy of 72.50% also highlighted when comparing the result of very high potential and high potential area affected by drought with the 2018 data. Furthermore, a convincing 100% accuracy was obtained when comparing the top-10 data of very high potential in droughts and 2018 data. As our future recommendation, We suggest more parameters to be included in the calculations and also to use a 3-dimensional GIS approach as a tool to visualize the information.

Authors: Lukman N , Irfan M , Nugraha A , Jumadi J
Published: March 2021

This paper proposed to discuss the complexity of scheduling by comparing two optimization methods between genetic algorithms with differential Evolution. Genetic Algorithms can solve the simplest to complex problems as well. Therefore, the Genetic algorithm is precisely applied to the scheduling of subjects. Then another appropriate optimization method for completing optimization is the Differential Evolution (DE) algorithm. DE algorithm is a fast and effective search algorithm in solving numerical and finding optimal global solutions. The steps of the two algorithms are initialization, participation, mutation, crossover, and selection. The scheduling system produces non-optimal schedules for teacher conflicts and empty slot schedules. After the genetic algorithm and differential evolution are applied, an analysis of the results of the subject scheduling is then performed by comparing the fitness values and the execution speed of the two algorithms. the genetic algorithm found only 2 perfect schedules out of 10 experiments, whereas in the implementation of differential algorithms, there are 7 perfect schedules out of 10 experiments. Thus, it can be concluded that by determining the value of the producing parameters 5, generation 50, mutation 0.6, and crossover 0.2, the differential evolution produces better output or conformity values using genetics.

Artificial Intelligence (AI) in the 21st-century is growing rapidly. Now human life leaves very little boundary between the real and the artificial. AI intelligence over time becomes more organic and results in the melting of boundaries between humans and AI. In the last decade, AI-Android and AI-Virtual have emerged which have increasingly blended the boundaries of reality. Through analysis of the philosophy of artificial intelligence in the spectrum of post-phenomenological embodied Don Ihde and Vincent C. Müller, it was found that one of the things that increasingly fused human reality and AI was gender choice. This choice has been proven to result in the dissolution of human and AI realities, and will further challenge humans to develop a philosophy of transhumanism. Because, if AI has been so organic and fused, then the development of AI will be in accordance, as well as with human development. If not said to be human itself.

Published: March 2021

The modern overhead lines with High Capacity Low Sag (HCLS) conductors can be operated at higher current carrying capacity. The main advantage of HCLS conductors is the special design of operating conditions, which cause the transformation of the mechanical pull load from the conductors to the reinforcing core. This transformation is called “knee point temperature”. This study aims to determine the knee point temperature and the effect on sag HCLS conductors. The simulation will be conducted on the HCLS conductors, namely ACCC/TW LISBON (310), which stretches between a span of 100meters. The electrical loading of conductors is gradually giving until a temperature of 180oC is reached. From the simulation results, we can determine the knee point temperature of the ACCC/TW LISBON (310) conductor is around 60-62oC. The value of the sag after the knee point temperature tends to be stable even though the ampacity loading is increased.

This study conducted a comparative analysis of system performance between Sea Waves-Hydroelectric Power Plant (SW-HPP) and Beach Waves-Hydroelectric Power Plant (BW-HPP) as a source of renewable electrical energy as the source of raw water for shrimp ponds, milkfish and salt farmers by taking research sites on the coastal coast of Marunda Cilincing, North Jakarta. Using the comparative method by comparing the parameters of pump force, water inlet speed, pump inlet pressure, water inlet velocity, pump inlet pressure, water discharge, turbine power and electric power generated. Assuming a sea wave height of 2 meters, a 4 second wave period, linear waves and turbine efficiency of 0.88. The results showed that both systems are very suitable as a source of renewable energy generation and raw water for shrimp or milkfish ponds in north Jakarta Marunda Beach. With the same system size, PLTA-GL generates more electricity than PLTA-OP. Increasing the capacity and availability of water in the PLTA-GL reservoir can be done by installing 3 pump units and 1 turbine generator unit. Increasing the power capacity of the PLTA-OP unit can be done by increasing the coverage of the trap unit.

Indonesia as stated in General National Energy Plan (RUEN) aims to achieve 23% of new and renewable energy in its energy mix by 2025. One of the ways to achieve this goal is by replacing existing diesel power plant fuel from fossil based diesel to biofuel and crude palm oil or CPO. CPO is envisaged very potential fuel substitutes especially for low and medium speed diesel engine due to its simple process to acquire and availability in Indonesia. This study aims to evaluate the viability of CPO utilization as fuel replacement for low and medium speed diesel engine compared to high speed diesel from economic perspective. This study uses levelized cost of electricity (LCOE) calculation to determine equivalent CPO price compared to its respected diesel price taking into account technical considerations and project life time. The impact of CPO usage for energy production to the palm fruit farmer also briefly discussed. This study finds that CPO is economically viable to be used as diesel engine fuel replacement under certain technical and diesel price considerations. The continuity of the replacement project also plays important role in determining the economic feasibility of fuel replacement by CPO. Certain incentives may be needed to be passed on by the government to maintain the sustainability of the replacement project.

Entropy is a statistical parameter that measures how much average information is generated for each symbol in a text. Each language usually has several important features that are hidden statistically and certain redundancy. These features can be utilized to form appropriate text compression tools for optimal use of resources. This study proposes an analysis of the entropy of the Cirebon language text for text compression using the Ternary Huffman Code algorithm. This entropy value then becomes the reference level of the Cirebon script compression level. The probability of each symbol in the Cirebon Regional Text is used to calculate the entropy value. The result shows the entropy of the Cirebon language script was 2.508 bits per symbol, with an expected code length of 2.565 bits per symbol. Estimated compression efficiency with Ternary Huffman Code is 97.77% and compression rate is 0.51308.

The use of a transmitter level detects the liquid level of a chemical percolation tank instead of a level switch, because the transmitter level provides accuracy in reading the value of the chemical fluid level. Ease of installing the transmitter level can be programmed and set up easily. The high price of a transmitter level causes entrepreneurs in the industrial world not to use the transmitter level as a reader or detector of chemical fluid levels in the production process. Based on this background, the chemical fluid level control device was designed using an ultrasonic sensor, by implementing Atmega16 as a controller. Controlling the level of chemical percolation fluid level using an ultrasonic sensor HC-SR04 as a reader or level detector. Drivers to run the motor when filling the chemical fluid tank of percol are run manually or automatically. The overall test results of ultrasonic sensors work optimum that is 75% of the 8 test data according to program settings. The average value of the ultrasonic sensor error to detect the level of percolating fluid in both tank 1 and tank 2 is 0.125 cm.

Death casualties due to electrocution when showering using electric shower water heater (ESWH) have been reported. The cases included the use of either water heater with storage system or the instantaneous water heater. There are three factors that may contribute to the event, namely, the improper installation including the grounding and wiring systems, the equipment factor, and the human error. The first two factors are the most dominant. This paper presents scenarios when one may experience an electrocution during showering, the current safety regulations in Indonesia regarding the installation of the electric shower water heater, and the mitigations to avoid casualties. The additional of ELCB (Earth Leakage Circuit Breaker) may increase the safety factor as it protects the user from an electrical shock in shorter duration than the common Main Circuit Breaker (MCB). A successful ELCB depends also on the correct installation of protection earth wiring and grounding.

Under Frequency Relay (UFR) is used to prevent the frequency instability of a generation outage by balancing the load with the supply. The approach of this paper is to design an Adaptive Under Frequency Load Shedding (AUFLS) model in power system simulation software by estimating the magnitude of losing generation using artificial neural network (ANN) based on the early response of frequency after the disturbance occurred then the shed loads will be obtained based on this value estimation. The New England IEEE 39 bus system is used for this dynamic simulation. There are three operation scenarios planned with different dispatches of the generators, each generator is simulated by removing it from the system then the frequency system response is used as training data for the ANN model. The analysis is performed by comparing the frequency response of the system using Conventional 4 Steps Under Frequency Relay Load Shedding (UFLS) and the Adaptive Under Frequency Load Shedding (AUFLS). The results show that the frequency response after disturbance using the Adaptive Under Frequency Load Shedding (AUFLS) revert to the initial frequency closer and faster than using Conventional 1 Steps Under Frequency Relay Load Shedding (UFLS).
