Abstract

This study was aimed to determine the level of CO concentration due to traffic flows, know the traffic (vehicle) volume, traffic (vehicle) speed and wind speed, find out the relationship between traffic (vehicle) volume, traffic (vehicle) speed, wind speed and CO concentration using a regression model as well as examine the parameters influencing air pollution due to traffic flows. The primary data used in this study were the sample data of CO tested directly in the field and the sampling was done using Ecoline 6000 Gas Analyzer tool. The research sites covered 1) the segment of Sam Ratulangi Street in Manado representing the street locations with many multi-rise buildings and high building density, 2) the segment of Ahmad Yani Street in Manado representing the street locations with many trees, and 3) the segment of Pierre Tendean Street in Manado representing the street locations with open areas (beachsides). In this modeling, the independent variables were the total traffic volume, the average traffic speed as well as the wind speed and direction. The dependent variable was Carbon Monoxide (CO) with increased concentrations. Using the three independent variables, there were total 7 (seven) variable combinations used. Then, the obtained model was validated using the surveyed data. The maximum vehicle volume was 4,281.60 pcu/hour (pcu = passenger car unit) and the maximum vehicle speed was 32 km/hour. Meanwhile, the maximum wind speed generated was 7.5 km/hour and the maximum level of air pollution (CO) was 12.86 ppm (ppm = part per million). In this study, it was obtained the best model for each of the three locations. The results showed that the air pollution (CO) level of street locations with low wind speed, such as Sam Ratulangi street which is a closed area with many multi-rise buildings and high building density, was much higher than that of street locations with many trees growing in the median of streets with a distance of 1 meter from the edge of street pavement and also higher than that of street locations with open areas (beachsides). This is because a higher wind speed can disseminate or divide the concentration level of air pollution (CO) to various places. Air pollution control covers three stages namely the prevention, countermeasure, and recovery of air quality.

Abstract

In accordance with Gorontalo Provincial Government Regulation No. 3 of 2016 concerning the Implementation of Information and Communication Technology-Based Deliberations, the Local Government (the provincial, municipality and regency government) is obliged to manage data in information system applications for internal and external interests by paying attention to the security of the application of communication and informatics, Gorontalo’s LPSE serves to ensure that IT organizations use resources efficiently, secure organizational assets, maintain organizational data integrity and security, and achieve organizational goals effectively. This corresponds to the Province ’s vision of e-Government. One of Gorontalo’s e-Government infrastructures is the e-procurement service. To find out whether the LPSE service is effective, evaluation is needed. This paper presents an evaluation of Electronic Procurement Services using COBIT 5 (Target Control for Information and Technology related version 5). By analyzing awareness management on the strategic plan for Electronic Procurement Services (LPSE) that need to be evaluated. Namely in the process (ME1) in terms of information technology performance, after conducting an Awareness Management analysis then measure the level of management ability by using the Maturity model to get maturity values for performance domain information technology (ME1) with a maturity value of 2,56. internal control (ME2) with a maturity value of 1,80. In accordance with external requirements (ME3) with a maturity value of 2,44. and information technology governance (ME4) with maturity values 2,99.

Abstract

Nowadays, many people who live in remote islands of Indonesia are still facing difficulties in terms of access to information. In the locations where end-to-end communication is not available, the asynchronous approach can be utilized to send information in the form of digital data. In some areas, we could utilize passenger ships or ferries as physical carriers to deliver digital data to the people in the remote islands which are located at a particular range of distance from the ship’s passing routes. This paper reports the channel performance of long-range WiFi connection oversea at 5 GHz using the real ship’s route at the North Sulawesi province‘s water in Indonesia as a sample scenario. The measurement results showed that the most stable ship-to-shore communication can be achieved in ±15 minutes at the maximum distance between the ship and shore of about 4 km. The maximum channel capacity was 120 Mbps for upload (from ship to shore) and 53 Mbps for download (from shore to ship), which is enough to deliver gigabytes of information to the people at the islands every time the ship passes by.

Abstract

The world energy crisis from non-renewable fossil energy sources greatly impacts the electricity sector. Meanwhile energy is needed to ensure food security is estimated at 38 percent of the energy consumed in the food system. Agrifood systems require renewable energy, access to modern energy services in rural areas, technology related to climate-smart agriculture. Hybrid technology makes it possible, we combine several new and renewable energy sources to save electricity more effectively and efficiently. Able to manage the shifting period of any renewable energy source in hybrid energy by the control system. In this case, each of these new renewable energies can be arranged based on their respective existence. With the existence of a power plant with renewable energy in the form of hybrid energy, it can also facilitate farmers in terms of electricity sources because in the most recent agriculture there is no electricity installed. With this method farmers can process the natural products they have easily, and are cost-effective.

Abstract

The post-harvest agricultural products handling is important to improve quality and to reduce yield loss Shallot is one of perishable agricultural commodities. Inappropriate post-harvest handling of onion can causes loss in weight, damage bulbs because of rotten, moldy, and new shoots grow. The traditional process of drying agricultural commodities can takes around 7-9 days under direct sunlight and 3-4 weeks depending on weather conditions when restore in the drying room. This causes more time for post-harvest processing and farmers to be needed. The installation of the automatic instore dryer provides a solution where the drying time is less than a week with the level of humidity and temperature are based to the target set point and not too dependent on outdoor weather. While temperature conditions under regulated temperature, the heating process uses light bulb while the air circulation inside the instore is using the exhaust. The output signal of the controller will activate the incandescent and exhaust lights based on the difference between the sensing temperature and humidity sensors installed in the room and set point.

Abstract

Process capability has long been recognized as an important performance measure to prove how well the process meets the requirements. Process capability can be improved by applying dual response approach, to determine optimal input factors. Using of artificial intelligence can optimize the prediction of the best input combination with a limited number of experiments. This study proposes an alternatives procedure using a dual response approach and artificial intelligence. One of the most common robust design models has been formulated to minimize variability while maintaining the mean on the desired target. A study case was selected to implement the proposed approach and compare it with conventional optimization models to show the improvement in procedures.
