Abstract

Climate change has a huge impact on the availability of water resources. Based on the case, this research is deemed necessary to do. Water availability is an essential issue related to climate change. The most perceived impacts due to climate change are climate anomalies; the rainy season lasts shorter with increasing intensity and the dry season lasts longer than usual conditions. The body of water cannot accommodate high-intensity rainwater, so it flows quickly into the sea. Relatively, a long dry season results in drought. The vulnerability of the availability of water sources in the Kalangkangan watershed, Tolitoli Regency was indicated through the reduction in river discharge. This changes in discharge had the potential to be difficult in meeting the needs of irrigation or clean water. If there is no attempt to protect and repair the water sources, it is believed that the reduction in discharge will continue until it hits a critical condition. The availability of water from the rain - discharge simulation model in the Kalangkangan watershed for wet conditions (Q20%) had a maximum discharge of 20.62 m³ / sec in June (decade II), and an average discharge of 13.59 m³ / sec. For normal conditions (Q50%) the maximum discharge was 19.47 m³ / sec in June (decade I), the minimum discharge was 5.35 m³ / sec in June (decade I) and the average discharge was 11.13 m³ / sec. For dry conditions (Q80%), the minimum discharge was 5.18 m³ / sec in May (decade I) and the average discharge was 9.05 m³ / sec

Abstract

program (unreached population) such as clients who visit independent practice health services, clients who seek treatment themselves with alternative medicine or buy drugs at pharmacies that are not in accordance. This study aims to design a model that can help the government in HIV case through counsellors aiming to reduce the spread of the infectious diseases. Methods: The type of research conducted is applied research. This research designed and built a model to help counsellors and clients during the treatment period. The study was conducted in Palu City with a number of samples scattered in 8 Voluntary Counselling and Testing (VCT) clinics . Results: The model developed resulted in an Electronic HIV Control and Counselling Care (E-HC3) application that can help counsellors dealing with large numbers of clients and are private. Applications built have three levels, in which the first level is as a super admin (government), the second level is an admin (counsellor) and level three is the client . Conclusion This app is very helpful for counseling HIV-AIDS counselors and clients based on application testing. It is known that the E-VCT application counselor's assessment of the total percentage value of the five variables tested was 80.10% with a very good acceptance rate from the user of the E-VCT Application.

Abstract

Introduction : The increase of population in Palu City has result in increased vehicle ownership and increased the risk of traffic problems such as traffic accidents. Sofar, the accident data in the Palu Resort Police Station has not been fully utilized by the interests of related parties. Therefore, the accumulation of data will be processed by data mining techniques. This study aims to cluster the level of accidents in Palu City based on the age of the perpetrators, where the results of the clustering will be used as consideration for the more targeted socialization of traffic accidents. Based on the results of testing with 2 different centroid initialization methods, the results obtained indicatethat centroid initialization using the ranking method has an SSE value of 233.0690397 while centroid initialization using a random method has an SSE value of 356.42304. It proves that centroid initialization using ranking method has better clustering results compared to centroid initialization experiments using random methods.

Abstract

Introduction : Microclimate is one of the environmental sciences related to plants in an area. This science describes the climatic conditions of the environment that have living organisms around it, either close to the surface of the earth or in confined environments such as a room, factory, and greenhouse. Measured the scale of studies of microclimate and environmental-climate vertically ranging from 1 meter to 2 meters. This research study used a field survey method by collecting environmental temperature data and observing tree architecture models growing in the campus area of Universitas Tadulako. The results of the study confirmed the most effective tree architecture models in minimizing the ambient temperature by investigating the aesthetic criteria of tree structures and characteristics in the campus environment of Universitas Tadulako.

Abstract

Introduction : Sulawesi coals contain significantly high of sulfur. This makes it not suitable to be used as fuel, unless it went through an engineering process so that the use of low-rank coals can be optimized by preserving the environmental impacts that may be caused. The process is in the form of upgrading the coals through physical desulfurization and dehydration with blending method. The purpose is to make coal meet the fuel use standard in industry. This study used low-rank coal from Pattuku (BP),while the high-rank coal studied was from PT Semen Tonasa (BT) on a dry base with a size of 100 mesh. The variables observed were the smallest total sulfur content, the largest calorific value, and the smallest (optimal) water content. The results showed that the total sulfur content in all variations of BT:BP ratios are 1:0, 3:1, 1:1, 1:3 and 0:1. Thus, based on the ratios, the coal fulfilled the standard to be used as fuel for cement industry while the variation of BB that fulfilled the standard to be used as coal-fired power plants had ratios of 1:0, 3:1 and 1:1. The smallest (optimal) total sulfur level was 0.1046% at the BB ratio of 1:0. BB water content in all variations of BT: BP ratiosmetthe standard to make it as fuel for cement industry and coal-fired power plant (PLTU). The smallest (optimal) water content was 2.48% on the blending coal ratio of 0:1. The calorific values of BB on all variations of BT:BP met the standard to be used as fuel for cement industry had ratios of 3:1, 1:1 and 1:3,yet there was no single BB that metthe standard to be used as coal-fired power plant (PLTU). The largest (optimal) calorific value was 6.506.39 kcal/kg at the BB ratio of 0:1.

Abstract

Introduction : Technology is a supporter in making decisions made by a top-level leader. Good decision making will produce a good decision. An example of decision making is the determination of an honorary employment appointment at an agency. In some areas, there are still various offices or government agencies whose recruitment process has not been carried out professionally, but still in the usual ways in the environment such as friendship or family relations. This research designed a web-based decision support system application using SAW method to support the labor selection process at the Class II Agricultural Quarantine Center in Palu. The type of research conducted is qualitative descriptive study. The system development method used in this research is Waterfall development. Waterfall method is the workmanship of a system carried out sequentially or linearly. The analytical method used is Simple Additive Weighting (SAW). This method used because the basic concept of SAW method is to find a weighted sum of the performance ratings on each alternative of all attributes. The programming language used is PHP, while the database used is MySQL. The method used to test this system is black box testing method. Based on manual calculations as a comparison with the calculation of the system built, it can be obtained same results for its value. In addition, the results of ranking was obtained, where the alternative manual calculation that has the highest value is Fadila with a vector value of 1.00.
