Water is essential for life. Frequent water disruption in Malaysia caused turbulence in daily lives and livelihood of thousands Malaysian. The water operators in Malaysia are facing serious challenges to ensure consumers have continuous access to clean water and to ensure a sustainable water future. River pollution in Malaysia had been identified to be one of the causes of water crisis in Malaysia. Hence, a continuous monitoring system utilizing the concept of Internet of Things had been proposed in this paper. Agile model is used due to its simplicity. The water’s pH measurement, turbidity, temperature and flow can be measured and the reading will be sent to end-user. The sensors that detects the pH value, turbidity, temperature and flow measurement of a water sample will pass through the information to the Arduino, and the result will be shown on the mobile devices via an app called Blynk. This portable and comprehensive prototype is suitable to be used in Smart Cities where WiFi signals is available as the transmission medium.

This study aims to determine the capability of seaweed (Eucheuma cottonii) as a bioplastic material on varying concentrations of glycerine (10, 20, and 30mL) in terms of (1) tensile strength, and (2) biodegradability. In making the bioplastic, the researchers dried and extracted several seaweeds, used glycerine as the plasticizer, water as the solvent, corn-starch as the thickener, and vinegar to help the starch dissolve easily. After mixing all the ingredients on a hot pan, we placed them on a flat surface lined with foil as soon as possible before the product starts to solidify. It took 3-4 days to harden, depending on how thick the product is. The results in testing the tensile strength revealed that the less amount of glycerine allowed the harder bioplastic produced. The biodegradability test showed that glycerine components caused the plastics to differ in size, shape, moisture, texture, and how fast they degrade, as well as the tensile strength. However, in testing biodegradability, there is no significant difference in the level of glycerine concentration. This study presents how the seaweed bioplastic was created, what it contributes to the community, and how the ecosystem benefits from it, such as reducing the usage of synthetic plastic.

Cds and CdTe both are effective absorber semiconductors for thin-film solar cells. It is a naturally n-type material, which has a direct bandgap value of 2.42 eV at room temperature It has great importance in light detectors in this work, CdS thin films (TF) were synthesized on glass substrates by RF Magnetron sputtering technique in an inert gas atmosphere. The electrical properties of CdS were characterized by the Van Der Pauw method. The films showed p-type conductivity, while the films deposited at different annealed times exhibited n-type conductivity. The resistivity of the CdTe films decrease as the conductivity increased. As the source rate was increased, the hole concentration in the as-grown p-type CdTe films increased. It was also reported annealing process affects the electrical properties. Al doping CdS the value of resistivity becomes minimum as the resistivity becomes maximum although mobility has maximum value after an increase in Al doping the mobility value. As a result, the CdS/CdTe thin-film showed enhanced electrical properties for solar cell applications.

The Industrial Internet of Things (IIoT) provides connection among devices with the ability to monitor and exchange sensor data through the Internet. The need for reliability and high-quality data, as soon as possible that data monitoring able to afford the requirements from the IoT industrial standards. Recently, researchers have created more suitable communication protocols for IIoT devices, of which each has advantages such as XMPP, MQTT, AMQP in which MQTT is most widely used. This study proposes the utilization of MQTT as a communication protocol, which is one of the data communication protocols for IIoT. This work used temperature and humidity sensors, accelerometer sensors, current and voltage sensors because the digital and analog parameters are often needed as parameters of IIoT conditions. Data were scaled in real-time and stored in MySQL database. This study is also completed by mesh networks to deliver data from source to destination efficiently, these nodes using MQTT-based publish and subscribe. The result of this work demonstrates the transmission of data quality and reliability using MQTT protocol and the efficient power saving in mesh networks.

This paper presented a smart moving-spiral-clothesline for urban life. The design of the clothes dryer is flat and used in the manner of spiral movement. 3D models have been designed to show the basic component of the proposed smart clothesline. To evaluate the proposed system, the simulation results have been set up to show the operation of the proposed system. The proposed system of the clothes drying rack (spiral moving type) can support the drying weight of 2.5 kg per one drying time, which can save 68.2% of the space compared to old clothes drying (fix type). This, consequently, can assist in terms of movable space. The proposed system can also analyze the situation when dust affecting the drying may damage clothes from the simulation of the operation of the device and the sensor. It is found that the proposed equipment can be used in the actual design. In addition, t is necessary to adjust the light value to suit the installation area to prevent equipment failure.

This study investigated the effect of the ratio of the electrolyte paste mixture of cassava peel (CP) and pineapple peel (PP) on the voltage and current strength. In the experiments, prior to using, CP and PP biomass waste was cleaned then soaked for 30 minutes. Furthermore, the biomass waste is mashed and put into the test media according to the comparison. In this study, CP/PP compositions were varied with the value of 100: 0, 75:25, 50:50, 25:75, and 0: 100. The results showed that the highest electrolyte obtained by voltage and current strength with a ratio of 100: 0. The more CP comparisons used, the greater the voltage and strong current. This research is potentially used as one of the renewable alternative energies and can utilize existing biomass waste.This study investigated the effect of the ratio of the electrolyte paste mixture of cassava peel (CP) and pineapple peel (PP) on the voltage and current strength.

Publisher : Universitas Pendidikan Indonesia (UPI)

Art learning activities in schools are learning that must be done in practice, but currently many art educators do not provide maximum learning for students, and free students to be creative without giving directions. So that in this study it is hoped that students can understand the importance of art practice to develop students' creativity and explore the potential in students. In addition, this study aims to provide insight to junior high school students to understand that the application of an alum fixator in the process of making eco print batik can provide a new experience in the practice of fine arts at school. The method used is using quantitative methods by making 2 sessions of distributing questions, namely pretest and posttest after distributing the material delivered through PowerPoint and videos of the eco print batik making process which are analyzed in the form of statistical diagram tables. The results of the study produced a fairly good impact on the learning process, almost the entire sample of students who joined this study understood it well and wanted to apply it one day.

In the present study, we discussed the best techniques for the clear scan of the spine. For this investigation, it was found that magnetic resonance imaging (MRI) is a better technique as compared to others. It gives proper images and results in the case of hard tissues like the spine compared to X-Ray and computed tomography (CT) scans. It is also better in sense of it has a small radiation risk as compared to X-Ray and CT have some radiation hazards to patient health. Thirteen patients were scanned by MRI technique and the result was evaluated. It is a non-invasive technique and is used for different pathological diseases. It was found that most doctors and surgeons preferred the MRI techniques in the case of the Spinal Cord. Many radiologists exercised X-rays, CT, and MRI methods for viewing clear images of the spine. It was concluded that MRI is the best technique than X-rays and CT scans. MRI is a modality choice for the evaluation of soft tissue changes in the case of Cord. In the case of the Spinal Cord MRI better evaluates changes in spinal cord compression due to its high-resolution property. The CT could not tell us about the soft tissue change in Cord however it more clearly tells us about the fracture of vertebral bodies and posterior elements.
