This paper presents the recent development of transportation system in Saudi Arabia. Review of transportation system developed in the last three decades including air, land, sea and rail transportation. Problems raised from each mode of transportation were addressed and possible solution were provided. The results indicate that air transportation could provide the necessary needs of the Kingdom of Saudi Arabia in international connections while domestic air transportation provide limited passenger transportation for relatively long distances. This mode is limited to high income people and cannot serve short distances in effective way. Sea transportation could provide the country with freight transport but limited to passengers only in the Golf region or in the red see with some African countries. Road and highway provide the most transportation used by the public but associated with several problems such as environmental pollution, large number of road traffic accident and became the first cause of death in the Kingdom. Bus and car public transportation need essential improvement to meet the demand and save transportation for the public. Rail transportation seems to be the most sustainable transportation in future transportation in the country. Saudi Arabia late pay attention to rail transportation and recently intensive budget invested in rail transportation. Further development in rail transportation in the Kingdom is needed.

One of the problems faced by the state-owned electricity company (PT. PLN) in Indonesia is the difficulty of monitoring the progress of an ongoing project so that it requires a technology that can help project managers in monitoring project implementation. The data in this study consisted of 117 Win project data and 89 Lose project data with a total of 206 data. The system development used extreme programming with algorithmic testing, namely the configuration matrix. The result of this research showed that the model could produce an accuracy of 92.68% with an error percentage of 7.32%, which means that the model produced good accuracy in implementing the C4.5 algorithm in recognizing patterns of project development. The first implication of the proposed approach is that it can establish project work monitoring services. The second implication is that project managers can improve company performance

The stunting or malnutrition in toddlers are the main problems facing society today[1]. Also, the fact that these young children experience lack of adequate nourishment in Indonesia is quite indisputable. Handling nutritional problems is closely related to the strategy of a nation to create healthy, intelligent and productive human resources. Efforts to improve quality human resources begin with how to manage children's growth as part of a family with good nutrition and care For this reason, this study takes part in supporting the alleviation of cases of malnutrition by using the Simple Additive Weighting (SAW) Method which is used to find the optimal alternative from a number of alternative criteria. The basic concept of SAW is to find the weighted sum of the performance ratings for each alternative across all attributes[2]. The SAW method requires a decision matrix normalization process (X) to a scale that can be compared with all alternative ratings[3]. The SAW method recognizes 2 attributes, namely the benefit criteria and the cost criteria. The method used was Simple Additive Weighting (SAW) which consists of 2 criteria, namely Height (TB) and Weight (BW) according to age for toddlers. The calculation accuracy of this application is 90% of the tested data

This study purposed to identify urban street-side greenery’s effect on people's preferences towards streets in Malang town, Indonesia. Nine samples of streets were randomly selected based on greenery conditions and street typologies. Thirty participants for each street systematically selected came to a total of 270 respondents. The research instrument was a questionnaire with photos of the nine streets as stimuli to explore people's preferences towards street-side greenery based on six street greenery variables and two street conditions using multiple rating scales. The data analyses employed a descriptive statistic to determine people's preferences and multiple regression analysis to identify street greenery attributes that influence people's visual preference of the street. The results show that all street greenery attributes significantly influence people's preferences (p .05). As a whole, street-side greenery attributes, i.e., plant height, green street median, vegetation arrangement, the distance between trees, tree and vegetation species, and the number of trees, determine around 17.2% of urban street visual preferences. Among those street greenery qualities, the number of trees, vegetation arrangement, and green street median existence have the most influence on people's visual preferences. However, other than street greenery attributes, the street conditions (i.e., street width and the sidewalk width) significantly contribute to people's preference. It accounts for around 49.4% of the visual preference of the street.

This study aims to investigate several elements as a form of threshold in the urban settlement. Threshold has the function of connectedness and separation, which is an integral part of spatial practice in urban settlements. That is how humans have the freedom to regulate their activities and space by using the threshold as connector or separator. In particular, this paper describes the elements function as a threshold for different conditions to connect and separate human roles and activities. The extent to which activities occur in a particular space and time in urban settlements is the key to determining the shape of the threshold. This paper presents an overview of the forms and performance of threshold that exist in urban settlements based on everyday practices. It not only discusses the function of elements as a threshold but also reveals the relationship between in-out of the everyday practice in urban settlements. The presence of thresholds in urban settlements is not only limited to physical elements. In this paper, we argue that the threshold element can produce a different performance due to the interacting activities between space and time. So that the understanding that connecting and separating cannot be seen as something fixed, but depends on other aspects that occur in everyday practice. This paper provides another understanding of the performance of thresholds in urban settlements, and this can be carried out in the development of a dynamic and transformative urban spatial design.

The use of logistics service providers in Indonesia progressively increasing from year to year, especially XYZ company as warehouse service providers with main activity are product distribution and storage of finished good. Currently, the XYZ company uses a web-based system to record products in warehouse activities, but this system has not been able to measure and evaluate warehouse performance. In addition, the company has large operating cost caused by product handling costs and warehouse operating costs. In this study, a monitoring system was designed that can measure and evaluate warehouse performance to be a sustainable warehouse. Therefore, this study integrates Supply Chain Operation Reference (SCOR) and Analytical Hierarchy Process (AHP) by considering green warehousing criteria. The weighting of importance level of each criteria using AHP method results in make criteria getting a weighted score (0.421), plan (0.213), deliver (0.152), source (0.119), return (0.064), and environment (0.032). The results of the scoring system using OMAX show that 7 KPIs are included in the green category, yellow category (11 KPIs), and red category (10 KPIs). Total value the company's green warehouse performance index is 11.15 which indicates that overall warehouse performance has not reached expected performance based on Traffic Light System Method.
