ABSTRACT - The aim of the study is to investigate the potential use of dewatered sludge cakes in mortar properties as building material. The sludge was collected from water treatment plant and the percentages used in the mixes were 2%, 4%, 6%, 8% and 10% by weight of sand in mortar. The specimen without sludge was prepared for comparison. The testing involved chemical analysis of sludges as well as compressive strength for hardened state properties. The samples were cured at 7 and 28 days, and the average of three samples of 50 mm cube samples was measured. Two types of mixes with different ratio of sand were used and compared in terms of performance in strength. The results revealed that the waste sludges had higher components of Zn, Cu, Pb and As which was trace element concentrations in the dry sludge samples. Comparisons of strength were made from two different types of sand ratio used in the mixes. It was observed that sludge in mortar performed better when mixed with ratio of 1:3 compared to 1:6. The optimum results of waste sludge mortar were denoted from the replacement of 2% of sludge in the mortar. It can be concluded that waste sludge as a result from the process of water treatment can be utilized as partial replacement of sand in mortars.
Key Words: sludge, compressive strength, mortar, mix design, performances.

ABSTRACT - The central focus of the implementation of Outcome-Based Education (OBE) is structured educational system, which focuses on what students are able to do successfully at the end of their learning experiences. In short, the ultimate outcome of OBE is student learning. With regards to the preset study, the focus is on language learning. Successful language development is associated with active out-of-class learning activities engagement. Against this background, this Out-of-Class Learning Inventory (OoCLI) is devised to assist teachers in engaging students’ out-of-class language learning. In doing so, an Outcome-Based Assessment (OBA), ELC231 test battery is used as the assessment to be measured. The items were devised based on generated themes from semi-structured interviews of 11 informants, which were then validated using Item Objective Congruence (IOC) method. A total of 65 students responded to the 6-point Likert scale survey and this is followed by scrutinizing the validity and reliability of the items using Rasch Measurement. 4 criteria were employed, namely item and person reliability, separation index, item fit and item polarity. Item reduction were done to gain the best fit of the items to Rasch model. A total of 14 items were deleted, leaving only 20 items with 1 open-ended item. Having shown evidence of high reliability and statistical validity, OoCLI may therefore be employed for assessing students’ out-of-class learning, as well as a self-assessment inventory for the students.

ABSTRACT - Food and beverages industries are among Malaysia's most influenced and among the top industry ranks. Particularly for Shariah enforcement purposes, it is becoming the most essential issues to be discussed further. For better understanding, this study will focus on assessing the companies' performance for food and beverages that follow Shariah compliance as the demand for halal products is keep increasing day by day. To be more specific, the dependent variable of this study is return on asset (ROA) meanwhile the independent variables are total asset, quick ratio, inventory turnover, and debt ratio to complementing this study. Annual reports for selected companies have been collected from Osiris and Eikon Thomson Reuters for year 2013 to 2018. Findings from previous studies is expected to give direction to this investigation, for instance total asset, quick ratio and debt ratio will be significantly positive with return of assets. Meanwhile, the inventory turnover will be significantly negative with return of assets.
Key Words: Profitability, Food and Beverages Industry, Shariah Compliance.

ABSTRACT - State of the government found out that the major factor lead to environment cleanliness issue is due to lack of self-awareness among the citizen. The major pollution happen was water pollution where plastic waste were being littering into the ocean, rivers, and lakes. There are a lot of prevention problems that have been implemented such as manual cleaning perform using nets, enforcement of laws, and launched the awareness campaign that does not resulted to a great impression. This project designs the semi-automatic robot called as ‘Marine Robot’ that using Bluetooth module, Arduino Uno as a microcontroller, DC motor, servomotor and ultrasonic sensor to drive the system. The proposed system resulted to semi-automatic water surface cleaning process that could be controlled by human to improve the quality of environment especially in water pollution. In future work, rain sensor can be done to improve the system design.

ABSTRACT - Students need a transport to go anywhere they want to go. In Malaysia, Grab and myCar are the most known e-hailing services. For UiTM Seremban students, its hard to get transportation like Grab because it is limited in UiTM Seremban area and because of that, the cost of using this services is a bit high. Most of the passengers want the driver who can provide them a comfortable service, make them feel safe and can minimize risk during their riding. In term of selecting driver, some students prefer to find the driver which suit with his/her need. The use of star rating in this application will help the passenger to rate the driver and based on the rating given it can help the other passenger to decide in choosing the driver according to the ranking. Currently, using grab and myCar, passenger cannot choose their own preferred driver. Therefore, by developing carpooling mobile application, it will give a chance and some advantages to the passenger for deciding by their own, according to their need to choose their own preferred driver. Moreover, it also helps the student to save their time of waiting the driver because the passenger can select nearby driver around them. This carpooling application uses Average Rating method before generates the lists of the driver. The higher rate driver is the top driver while the lowest total rate is placed at the bottom. At the end of the study, it shows the mobile application that lists the driver from the highest rating to the lowest rating based on their average to help the passenger to select their own driver when they want to carpool.
Key Words: e-hailing, carpooling, mobile application, Average Rating method.
