Abstract
Critical air quality levels lead to an unhealthy environment which disrupts physical activities and human health. Wet deposition of air pollutants might cause a high concentration of water pollution due to rain water washout of nitrate and particulate matter (PM). This study aimed to investigate the impacts of air pollutants deposition on river water quality in Malaysia. The methodology involved in the analysis of secondary data (January to December 2013) for air quality and river water quality using factor, correlation, and regression. Parameters of air quality were PM10, Nitrate (NO3), ozone (O3) and temperature while water quality data were turbidity, Nitrate and PM10 (Ca, As, Hg, Cd, Cr, Pb, Zn, Cl, Fe, K, Mg, Na). The results show that there were positive correlations between air quality indicators and Kinta river water quality parameters. Correlation matrix shows that in terms of turbidity, air and water data were having 96% similarities. Regarding Nitrate concentrations, air and water records had only 30% of correlation matrix, which can be due to other sources of Nitrate which was agriculture activities near Kinta River. The factor analysis results showed that PM was the main contributor to river water quality particles with 94%.

Abstract
The vehicle growth is one of the problems affecting traffic congestion. The circulation of entry vehicles and circulating vehicles in confluence made the conflict point. Avoidance the conflict is the need to increase road performance. The roundabout of the road is one of the utilities to increase the performances of traffic and reduce congestion. The prevention step is to maximize the utilities to control and manage the traffic. The roundabout dispersed and controlled the traffic flow. According to Makassar roundabout observation, the queuing and delay of vehicles recently occurs. This study aims to an analysis of the roundabout using the microsimulation Vissim program. The model uses the geometric condition of the road and volume of the vehicle that produce the models based on real condition and validation. This model performed the visual condition and calculated the capacity and shows the emission of the operational vehicle, and the general performances are summarized for operation performances at roundabout confluence sections. The result indicated that the roundabout is still useful to reduce the potential of queuing and delay the time of vehicles, and it needs supervision periodically for preventing the traffic from the potential congestion, especially in developing countries. The research result is useful as a reference for improving the capacity of roundabouts.

Published: July 2020

Abstract
The origin-destination (O-D) matrix is fundamental data for transportation planning. It is a primary process for modelling approaches the public transport. Generally, the observation survey of O-D volumes takes much cost, time, and effort. Therefore, establishing an inexpensive and simple observation method is expected to be able to carry out the continuous observation of passengers O-D volumes. Defined that many problems in transport planning and management tasks require an origin-destination (O-D) matrix to represent the travels pattern. The need for low-cost methods to estimate current and future O-D matrix is even more valuable in developing countries because of the rapid changes in population, economic activity, and land use. In this study, the O-D matrix use for modelling trip distribution of passenger in the current and future situation and plotting the model with Visum as a macro simulation program. This study focuses on the O-D volumes on a line of local public transport service. The on-board observation is carrying out, and the frequency of service is observed. Then, the passengers O-D matrix is estimated. These results must be useful to improve the operation of the service of public transport.

Abstract
Voltage stability problems and renewable energy penetration in power systems are the main issues in the electric power system at this time. This paper aims to examine the condition of voltage stability at the time before and after the entry of wind power plants in the sulseltrabar interconnection system. There are two wind power-generating units that will be studied, namely the PLTB Sidrap with a capacity of 75 MW and the PLTB Jeneponto with a capacity of 72 MW. The simulation using Matlab program. From the simulation results, it can be seen that Sulseltrabar’s voltage stability interconnection system at the time of the entry of PLTB Sidrap and PLTB Jeneponto, has improved stability, this can be seen from the eigenvalue and bus participation factor values. From the minimum eigenvalues it can be seen that the penetration of PLTB Jeneponto is slightly better than PLTB Sidrap in improving voltage stability. The condition that has the greatest influence on improving stability is when the two wind power plant enter to the Sulseltrabar interconnection power system.

Abstract
There are three main requirements to meet the criteria both in the electric power system, namely reliability, quality, and stability. Stability is the ability of the system to return to work normally after experiencing interference. System stability analysis is a guide for operators to detect or prevent voltage drops and power outages. This research discusses the stability of the 150 KV electrical system in South Sulawesi before and after interconnection with the Sidrap and Jeneponto Wind Power Plant. The method used is the Line Stability Index (Lmn Index) to view the voltage profile. Index Lmn coding is run and simulated using Matlab. Validation is done by IEEE 14 bus simulation data, and comparing the results of the analysis before and after penetration with PLTB. The study was conducted on the Sulselbar 150 KV system before penetration with PLTB, namely 44 buses, 14 generators, and 52 lines / networks. The highest Lmn index result is the network from bus 38 to bus 39 that is equal to 0.0292. Second is bus 15 to bus 16 which is 0.0291, and third is bus 40 to 42 that is 0.0273. After penetration with PLTB Sidrap and Jeneponto, the number of generators will be 16 generators. The highest Lmn index results are from bus 38 to 39 that is 0.0292, then bus 15 to bus 16 that is 0.0290 ranks second, and bus 40 to 42 equals 0.0272 or keeps the third order. After the sidrap load bus is converted to a bus generator, the Lmn index before in reactive power supplied to the load by a generator is a certain thing, this condition must be maintained so that the plant continues to work in stable conditions.

Abstract
Jakarta as the country’s capital, has experienced a series of floods that crippled cities in 2002, 2007 and 2013 and extreme rainfall has always been the main cause of major flood with casualties and property. Given the increasing impact of flooding in Jakarta, methods for assessing current and future flood risks is needed. A model is needed that can predict and determine which areas have the potential to be affected by future floods. Several models have been carried out for prediction and assessment of flood risk in Jakarta and several other major cities, namely GIS based on SVM models, hierarchical process analysis models (AHP), machine learning with ensemble models, and multivariate discriminant, classification, and regression trees. However, from several methods there are still some weaknesses, one of which is the time to get a predictive model that is quite long, which is 3-4 hours depending on the amount of data. To overcome this problem, genetic algorithm rule-set production (GARP) and quick unbiased efficient statistical tree (QUEST) models can create a prediction model with a shorter time with the same results. Several factors that influence flooding are used as input model data: precipitation, slope, distance to river, distance to channel, depth to groundwater, land use, elevation, and flood data for 2002 - 2019. The Area under receiver-operator characteristic curve (AUC-ROC) and root mean square error (RMSE) were used as evaluations for model performance. The results showed that the GARP model (AUC-ROC = 94%, RMSE = 0.2) had higher performance accuracy than the QUEST model (AUC-ROC = 84%, RMSE = 0.4). The results also indicated that the distance to channel, land use, and elevation as important parameters in determining flood hazards.

Abstract
Mining activities disturbing large areas of land may increase erosion rate up to several hundred times greater than from undisturbed areas. The erosion process occurs in stripping overburden, excavation of rocks and minerals, dumping in stock file and waste dump, and mine reclamation. Since the eroded material/sediment becomes a big problem to the environment and for mining operations, estimation of soil erosion need to be carried out to create a good mine planning. For the early stage, a study of soil erosion was performed to classify erosion hazard level and to estimate soil erosion size. This study uses the Revised Unified Soil Loss Equation (RUSLE) method supported with Geographic Information System application for study area in the Block D1-D3 of Petea Mine Area. The study result showed that the research area can be classify into four erosion hazard level namely; low, medium, heavy, and very heavy with estimated material losses is 116,146.43 tons/year.

Abstract
PT. XYZ Indonesia is a national company engaged in animal feed production. through the Production Planning Inventory Control (PPIC) department has implemented the Material Requirement Planning (MRP) system for inventory control but in the implementation of the company’s MRP system, the PPIC department only considers the quantity of raw materials that can meet demand without regard to the issue of lot size inventory efficiency, so that the cost of raw material inventory is high. The purpose of this research is to compare the cost of procuring raw materials that have been carried out by the company with the cost of procuring raw materials using the silver meal method and Wagner Within algorithm. From the results of research and analysis conducted a comparison between the methods used by the company with the lot size silver meal method and Wagner Within algorithm in order to obtain the total inventory cost of raw materials in 2016, where yellow corn and rice bran raw materials have the same inventory costs between the methods used by the company, the silver meal method and the Wagner Within algorithm method are Rp. 1,080,000 so they do not have cost savings. As for the inventory of lime stone raw materials, it is more optimal to use the silver meal method and Wagner Within algorithm with a total inventory cost of Rp. 606,394 and can save costs by 35.08%.

Published: July 2020

Abstract
Currently, the ship container generation has allowed for the carriage of containers on deck up to four tiers high. The container loads in tiers high affect on deck structure. Consequently, an insert plate is used and located on the top of the ship deck structure for placing the container corner fitting. Sometimes container fitting is placed between longitudinal deck beams under without supporting construction such as pillar or carling. Therefore, this matter should be analyzed to obtain the strength behavior of the insert plate. This study describes the strength analysis using the finite element method (FEM) through ANSYS software. Based on the simulation results, the maximum Von Mises stress of the insert plate was obtained exceeds 181 N/mm2 and 235 N/mm2 in the initial condition, whereas the insert plate could support only 15% loads per corner fitting (three tiers high). Then, the thickness addition of the insert plate until 24 mm reduced the stress, however, the reduction was a small magnitude. By adding two carling construction is similar to the size of a transverse deck beam, under the insert plate, the stress was obtained 138.54 N/mm2.

World Music: A Very Short Introduction
Authors: Bohlman Philip V. 
Published: July 2020

Abstract
World Music: A Very Short Introduction looks at the history of world music and its many definitions. ‘World music’ is more than a marketing term for the music industry. During the Enlightenment, the idea of the ‘folk song’ encouraged European audiences to imagine music from around the world. Technology helped to create the ‘audio moment’—the transformation of sound into material which could be recorded and distributed worldwide. Throughout history, music has been used to express unity and national pride. World music both foregrounds and transgresses borders. Ideas in different cultures about world music, and indeed about music, are as diverse as ever.
The West and the world
Authors: Bohlman Philip V. 
Published: July 2020

Abstract
‘The West and the world’ investigates the unequal balance of power in the transcription, recording, and history of world music. World music may have been forged in the ‘Middle Passage’ from Africa to slavery elsewhere, but its musicians were nameless. Their music-making was documented by those with power. Collectors of world music have an anthological impulse, bringing together songs from different cultures. Johann Gottfried Herder’s collection of Volkslieder or ‘Folk Songs’ and two of the first anthologies on record—the Demonstration Collection and Music of the Orient—show that the products of the overarching anthological impulse can be very different.
Between myth and history
Authors: Bohlman Philip V. 
Published: July 2020

Abstract
‘Between myth and history’ begins with the 1932 Cairo Congress in Arab Music. The Arab contingent sought advice on progress, while the European delegates romanticized traditional Arab music. These contradictions, and Islam’s relationship with music, shaped the life-stories of three figures: 14th-century polymath Ibn Khaldūn; 20th-century Egyptian singer Umm Kulthūm; and ethnomusicologist Robert Lachmann, who found musical echoes of Muslim and Jewish pilgrims in Djerba, where he had been expecting to find local music fixed in time by isolation. The Mediterranean has inspired written and sung epics, which were translated into architecture and politics, taking them from myth into history.
Music of the folk
Authors: Bohlman Philip V. 
Published: July 2020

Abstract
If folk music made it possible to imagine world music, it did so from a European perspective. ‘Music of the folk’ examines what concepts of folk and nationality meant to Hungarian composers Bartók and Kodály and explores the global success of folk-inspired Celtic music. Musical pioneers often straddled two cultures, such as Leadbelly, who performed both rural Southern blues and more sophisticated fusion. Leadbelly’s story and others were documented by the Lomax family of folk musician scholars. The spread of polka across the world suggests that there is a place for folk music within world music, contradicting claims that the idea of world music encourages homogenization.
Music of the nations

Published: July 2020

Abstract
Looking at the contentious history of the Eurovision Song Contest, ‘Music of the nations’ considers the complex relationship between world music, nationalism, and the modern nation-state. In her winning song in 2016, ‘1944’, the Ukrainian entry Jamala switched from English to Crimean Tatar, a political reference to the Russian annexation of Ukraine. Zimbabwe changed its anthem from ‘God Save the Queen’ to an African song via ‘Ode to Joy.’ ‘HaTikva’ went from a chorus at an international congress to the Israeli national anthem. There are also supra- or international anthems like the ‘Internationale’, a standard of the socialist movement worldwide.
Diaspora

Published: July 2020

Abstract
‘Diaspora’ explores the effect of human displacement on world music after the ‘discovery’ of the New World by Columbus in 1492, which set off a chain of diasporas. The music of diaspora addresses both place and homelessness, wandering and the dream of return. Three diasporas are investigated, beginning with the Sephardic diaspora, which arose in turn from the expulsion of Jews from Europe; the displacement of Africans resulting from colonial slave trade; and the South Asian diaspora, which draws upon music to represent the post-colonial world. Diasporic music is diverse, including reggae, klezmer, bhangra, Bollywood, and hip-hop among other genres.
