Soy sauce is a liquid condiment originated from China and is widely used not only in China, but also in Asia including Cambodia. Although some soy sauces have been produced in Cambodia, their quality has not yet been widely recognized in Cambodia and the study of soy sauces in Cambodia is still limited. The objective of this survey aimed to collect information about the current status on soy sauce consumption in Cambodia, for future research and

White pepper (Piper nigrum L.) is commonly used in food products such as light-colored sauces, soups, salad dressing, and mayonnaise. In general, white pepper is produced by water retting that is known as traditional method. Therefore, this study focused on the optimization of white pepper processing from green pepper berries by pectinase enzyme. It was conducted in different pretreatment time (0, 5, 10 min), incubation at 40 °C for 16 hours and

Biomass briquette is made from many types of biomass materials such as rice husk and bagasse which is partially the city waste; however, they are potential energy sources and widely available in Cambodia. Rice husk and bagasse are becoming one of the useful energy sources to help reducing organic waste in the city once being converted into a ready-to-use form. In addition, to form the rice husk and bagasse to be in briquette shape, binding materi

Increasing waste disposal and energy demand are a problem in the city today. Densification of biomass waste from sawdust and tree leaves into solid fuel briquette not only reduces waste reduction but can also be an alternative source. Raw materials and binders are two essential variables, among other important variables, presented in this article. Fish oil extracted from fish residues is a combustible binder with a high heating value. Investigati

This paper presents flexural strength, flexural modulus as well as the weight percentage of porosity in specimen by mixing two kind of epoxy resins for Sikadur® 31 CF Normal and Sikadur® 52 TH. The ratio of mixed Sikadur 31-52 following by 100%-0%, 66%-33%, 50%-50%, 33%-66% and 0%-100%, respectively with 3, 6, and 9 days curing time. The aim of this project helps to choose the correct proportions for renovating archeological structures, and espec

This paper provided a design process of a new structure of Computer Numerical Control (CNC) machine that can move 3-axis simultaneously and is capable of engraving specimens such as wood and plastic properly. The fabrication method and machine control were divided into three major steps. Firstly, the mechanical systems of the CNC structure such as the frame, joints, and movable axis were built. Secondly, the electronic devices and microcontroller

This paper describes the mathematical model, control and simulation of 3DoF (Degrees of Freedom) robot manipulator moving in a three-dimensions Cartesian coordinate frame. The four Denavit-Hartenberg (D-H) parameters are used to determine the homogenous transformations matrices of the links of the robot and express the robot’s forward kinematics. Both link position and orientation are embedded in the homogeneous transformation matrix. The geometr

The robot localization is a crucial task that needs to be solved as a part of the navigation problem for an autonomous robot. In order to estimate the location of a robot in the environment, various sensors are used to extract meaningful information from measurements to acquire knowledge about the robot’s environment and motion. Due to the fact that the sensor uncertainty is random, it is impossible to find an accurate pose for the robot by only

Instead of using battery storage for operating the irrigation system that is driven by solar energy, the gravity irrigation system has been used and grown popularity nowadays. However, this system cannot provide the balance flow rate every irrigation time that is going to affect the quantity of water need to irrigate due to the fluctuated of the static pressure that remains in the tank. So, this study is going to develop a smart irrigation contro

This paper provides Simultaneous Localization and Mapping (SLAM) for generating a 3D map of an environment. It takes the approach of graph-based SLAM with loop closure detection in the use of RGB-D (Red, Green, Blue and Depth) camera to generate the 3D map of an unknown environment. In real-time applications, localization and mapping require both accuracy and robustness. Thus, in this paper, a lighter weight Intel RealSense d435i RGB-D (with buil
