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

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

Abstract. English, the official language of the entire world is a very tricky language to teach. In fact, every language varies to teach. English is a very old language and has undergone many forms of changes from Proto English derived from the Latin and the German culture to Modern English which was established after in thepost Renaissance period. Each version was simpler than it’s previous. Present-day English is the simplest adaptation of a very old Language and yet it is still difficult to teach this language effectively especially to those who speak English as a second language. This paper analyses the innovative and quite interesting methods we have in teaching the English language. We may have a number of teaching methods in between traditional and modern. Everybody has their own understanding and conclusions on teaching the English language. But this paper portrays combining these two types of how we can make our teaching very effective.

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.
