Abstract

Drinking water is one of the basic necessities for the quality and sustainability of human life. Until now, the population uses water sourced from refill water / bottled water by 21%, wells by 29% and rain water by 50% as the main source of drinking water whose quality and quantity are not guaranteed. The need for drinking water from domestic and non-domestic needs or also known as adequate water for basic human needs and other activities that require water. The need for drinking water in Kuala Kampar District is calculated based on population projections using three methods and the chosen method is the arithmetic method. From the results of these calculations, it can be estimated that the population in the sub-district will reach 14.194 people in 2038. So that domestic water needs are 8,88 liters / second and non-domestic water needs are 1,33 liters/second. So that the total water requirement is 10,21 liters/second. Keywords: Kuala Kampar, pertumbuhan penduduk, proyeksi kebutuhan air minum.

Abstract

The automatic voltage regulator (AVR) is a major component in generating electrical energy. To improve the performance of the AVR system, controlling the proportional integral derivative (PID)is needed because it has a simple structure, is very strong in system variations, and easy to understand. The main problem for the PID controller is determining the appropriate parametervalues for the values of the proportional constant (Kp), the integral constant (Ki), and the differential constant (Kd) to obtain the optimal transient response. In the conventional methodbased on trial and error, a more efficient method is needed, namely Particle Swarm Optimization (PSO), an optimization method based on a flock of bird population. The criteria the minimum errorintegral used as a fitness function in the PSO is the integral of time multiplied by squared error (ITSE). The parameter values used must meet the stability requirements, namely the stability characteristics of the Root Locus. PID control has a significant impact on the plant, this can be seen from the results that have a good level of stability. As for the criteria using the PSO-ITSEalgorithm has a better transient response. In finding these values and analysis using the Matlab software tools.Keywords:AVR, PSO, ITSE, Root Locus. transient response, Matlab

Abstract

Riau University (UNRI) Library currently uses 802.11ac Wireless Fidelity (Wi-Fi) network. Even though users have used an 802.11ac Wi-Fi network, there are still problems that are often felt by users when accessing the internet such as slow connections, frequent disconnections, and difficulty connecting devices to the Wi-Fi network. Based on these problems, it is necessary to measure the performance of the Wi-Fi network at the UNRI library. Measurements were made during dense traffic using Wireshark and nperf software. The measurement parameters are throughput, packet loss, delay, and jitter. The measurement results show that the throughput and packet loss values of the 802.11AC Wi-Fi network at the UNRI library are still in the good category, with an average value of 1.935 Mbit/s, and packet loss <3 ms. However, the measured delay and jitter values are quite large, with an average delay value of 355 ms and jitter of 848.56 ms.Keywords:Wi-Fi, Throughput, Packet Loss, Delay, Jitter, Access Point, Wireshark

Abstract

On this paper, simulation of short circuit fault is performed on electrical power system of Riau. The simulation is performed by using power system analysis software DIgSILENT PowerFactory and use international standard IEC 60909 for short circuit calculation. The simulation is performed by giving three phase fault to 150 kV busses on electrical power system of Riau. The simulation results are three phase short-circuit current, it used to calculate the minimum capacity of circuit breaker and for the selection of circuit breaker. With the selection of circuit breaker according the standard, it can ensure that circuit breaker can work properly as function on break the short-circuit fault and the it’s not causing other damage on system. The final results showed that the minimum value circuit breaker capacity in riau electrical power systetem is variated base on the location of where the circuit breaker applied. The value of minimum circuit breaker on near generator is more greater than the far from generator. The highest value of safe or minimum circuit breaker capacity on Riau electrical system is 18.36 kA and the lowest is 2 kA. Keywords: short-circuit, minimum circuit breaker, DIgSILENT PowerFactory

Abstract

Biochar can affect the microbial population and can act as an adsorbent in the soil. Palm shell potensially as a raw material for making biochar because it contains cellulose, hemicellose, and lignin. The purpose of this research was to compare the biochar characteristics of palm shells according to SNI. Biochar was pyrolyzed at 550oC for 30 minutes and activated using NaOH solution. Biochar from palm shells in this research has qualified for activated carbon based on SNI 06-3730-1995, with a ash content of 5,25%. Key words : Biochar, Palm shell, Ash

Abstract

Peatlands could contains water 20 times than it weight. Peat water is brownish red because it cointans high organic substances, therefore peat water should be treating before it can be used as clean water. Adsorption with activated carbon is potential as a method for remove color and organic substances on peat water. This research aims to investigate the characteristics of peat water and analyze the potential treating method for remove color and organic substances on peat water used activated carbon. The result showed color and organic substances on peat water was 1830 Pt/Co and 437,8 mg/L. High adsorption capacity on activated carbon could removed color and organic substance on peat water.Keywords: Peat water, adsorption

Abstract

One model of the transformation of rain into debit is the Hydrologic Engineering Center - Hydrologic Modeling System model or abbreviated as HEC-HMS, and one of the calculation methods is Soil Moisture Accounting. This model simulates the movement of water through and storing water in vegetation, at ground level, in soil profile, and in the groundwater layer. The purpose of this study was to calculate and analyze the resulting value of the Soil Moisture Accounting method with Root Mean Square Error calibration and for the Rokan Watershed with AWLR Pasir Pangaraian. This study uses rain data and discharge data with a data length of 10 years, from 2008-2017. This research took place in the Rokan AWLR Pasir Pangaraian watershed using the HEC-HMS program. Hydrological Modeling uses a calibration method which is the Root Mean Square Error (RMSE) method. Based on the nine calibration decisions, the value of Root Mean Square is best at approval I with a value of 99.10, while the value verification of Root Mean Square is best at reporting II with a value of 90.20425. Keywords: availability of water, HEC-HMS, Soil Moisture Accounting, RMSE

Abstract

The need for electrical energy is increasing along with population growth and increasing community activities, so it is necessary to add new energy sources to reduce fossil resources. One alternative renewable energy issolar energy using photovoltaic (PV). However, so that the load can still be supplied optimally, one alternative solution is to use a hybrid generator technique. Hybrid system is the concept of combining two or more energysources. One of the hybrid power plants that has the potential to be developed is a combination of PV and generator. This research makes a hybrid PV-generator generating system to serve the maximum load and complement each other's shortcomings and add a battery as an additional generator. This research creates a coordination of generators to interact with each other between generators to serve load patterns in a structuredand simulated manner in MATLAB 2016a. The design of the hybrid power plant is PV with 58 kwp power, 30 kAh battery and 25 kva generator. The results in this study show the performance of each generator whenserving the load. Loads of 10 kw, 20 kw and 30 kw are supplied by PV and batteries. At peak load, the load is supplied by a hybrid PV-generator or battery-generator. From the simulation results show that the generator isable to overcome any given load with a given coordination system.Keywords : Photovoltaic (PV), Hybrid, generator, load, Matlab 2016a
