The human population increases every year, reported from the official website of the United Nation, in 2011 the world population reached 7 billion people. Then in 2016 reached 7.4 billion people and the world population in 2020 reached 7.7 billion people. It is estimated that by 2030 it will grow to 8.5 billion people and by 2050 to reach 9.7 billion inhabitants. which makes energy needs also increase. With these facts, we design gasification stove biomass energy that aims to reduce the use of non-renewable fuels. The study aims to design a rice husks gasification stove to minimize agricultural waste. In this study, there is an innovation in tar reduction using dolomite as a catalyst. This research uses qualitative research methods that are presented descriptively. The gasification stove design is inspired by the oil stove with the addition of an iron pipe that serves as an oxygen supplier. The design of gasification stoves using rice husk as fuel was successfully carried out. This stove is proven to be one of the tools to maximize the potential of using rice husks as fuel. Finally, we hope that this research can continue to be refined in further studies to maximize the utilization of rice husk waste as renewable alternative energy.

This study aims to determine the possibility of organic mosquito patches as an alternative to mosquito repellents. The results showed that the control group, namely commercial mosquito patches, was able to obtain the highest rate of repelling mosquitoes. However, statistical analysis did not show a significant difference in the three patches. Thus, the manufacture of organic mosquito patches is as effective as commercial mosquito patches at repelling mosquitoes. In addition, organic mosquito patches have the most economical product compared to commercialized patches. Thus, making organic mosquito patches is not only as effective as commercial mosquito patches but also much more affordable than they cost. It is recommended to use an organic mosquito patch as an alternative to mosquito repellent.

This study generally aimed to determine the effectiveness of kamias, star fruit, and karamay fruit extracts in removing stains. Previous studies revealed the effectiveness of Kamias as a stain remover, while, this study compared the effectiveness of different fruit extracts as a stain remover and the potential utilization of other fruit extracts from trees that are locally available. We determined the cost of making stain remover using kamias, karamay, and star fruit extracts, the ability of these fruit extracts as a stain remover in terms of the degree of strain reduction and whitening of the cloth, and ultimately, the significant difference between the various treatments. Results revealed that the use of star fruit extract was the cheapest among the four treatments while the highest cost was incurred using Karamay extract. There was a significant difference observed between treatments. Bleach was the most effective in removing the stains and whitening the fabric, followed by the kamias extract. In terms of removing stains, whitening the cloth, and availability in the neighborhood, the extract was found to have the best results. We, therefore, recommended the use of kamias extract as an alternative organic stain remover for fabrics and be used by the households. Being derived from natural fruit extract and contain no dangerous chemicals, the product is safe for human use and environment-friendly.

We present the design of bandpass filter on the frequency of the QZSS satellite, by providing bandwidth at the cut-off frequency equally to the bandwidth of the QZSS L1 with selecting the response characteristic on Butterworth maximally flat amplitude. Bandpass filter design using frequency of the QZSS L1 with bandwidth is 24MHz. The design procedure involves two steps, the first step is to find the required order of the filter, which we use 3rd order, and the second step is to find the scale factor that must be applied to the normalized parameter values. The Band-Pass Butterworth filler is a combination between low pass and high pass. For the Butterworth filter, the value of a resistor that has been used are 50Ω. Then go to find the capacitor and inductor and by using PSpice as the tools for the simulation. The results of the output of bandpass filter at -3dB was between 1563 and 1587MHz. And was bandwidth around 24MHz. The combination of the lowpass filter and high pass filter is to perform as the bandpass filter. Therefore, there are two combinations also in designing bandpass filter. The aim of this combination is to have an influence on the performance of bandpass filter. As a conclusion, this designed filter on the frequency of QZSS L1 is to be useful by using bandpass filter.

The purpose of this study is to assess the effectiveness of paracord anklet and bracelet made up of guyabano (Annona Muricata) seeds and wormwood plant (Artemisia Absinthium) extract as mosquito repellent and to determine if the paracord anklet and bracelet can be as effective as the commercial patch used in this study. In the study, 2 groups were examined: The experimental group and the control group. The experimental group with variation 1 (50 guyabano seed, 80% of water, and wormwood extract), variation 2 (75 Guyabano seed, 50% of water, and wormwood extract), and variation 3 (100 Guyabano seed, 30% of water, and wormwood extract). The control group was tested with the commercialized patch. Results showed that the overall gathered data showed very promising effectiveness, with a level of effectiveness of 6.5 means. Furthermore, the ANOVA showed no differences at all between the Control and Experimental Group (fcalc 2.20fcrit3.49, P=0.13). This may therefore mean that the paracord anklet and bracelet made up of guyabano and wormwood plant is as effective as the commercial patch used in this study. This study shows that the paracord anklet and bracelet can be considered as an alternative and environmentally friendly mosquito repellent.

Each student got their learning style. In skills institutions, students' learning styles are more visual and kinesthetic than auditory. This is because teachers who do not diversify the teaching system will impact their students. Besides, students will become bored and lose focus due to non-interactive teaching sessions. Teaching aids also act as a tool that can provide fun and a more profound interest in teaching content. Moreover, the application of high-tech skills that match with the era of the industrial revolution 4.0 will improve skills and knowledge. This study aims to improve the teaching quality for the Course DMC2333 Water Cooled Chiller and Air-Cooled Chiller course. In this study, researchers have chosen the ADDIE design model as a guide in developing this product. The evaluation was done using a questionnaire that has been certified by three experts in mechanical, especially in the field of Refrigeration and Air Conditioning. The items developed by the researcher are divided into three primary constructs, which are design, development, and functionality. Each section was divided into several things that help in answering the research questions. The findings found that all experts agreed with the items in the questionnaire. However, there are also comments and suggestions for improvement attached by each expert. The results of these comments and enhancements can help researchers further improve the product's effectiveness in the following study.

Portland Pozzolana Cement (PPC) is prepared by adding Pozzolanic materials to ordinary Portland Cement. The artificial pozzolana materials used in the manufacturing of PPC such as fly ash, silica fume, rice husk, blast furnace slag, are actually industrial waste, which is produced in large amounts. These artificial pozzolana materials when used in concrete can reduce consumption of natural resources, diminish the effect of pollutants in the environment and it is economical and reliable. The main objective of this paper is to focus on the properties and applications of Portland Pozzolana Cement and make effective use of different industrial by-products in the manufacturing of cement. We found that both PPC and ordinary portland cement (OPC) are commonly used types of cement in construction. Nowadays, PPC is used as a substitute for ordinary Portland cement (OPC cement). Since PPC contains pozzolanic materials, it helps to enhance the strength of concrete. The quantity of PPC required in making the concrete is less when compared to OPC. PPC is a green material that contributes towards sustainable development.

Road safety becomes a major concern for the regulatory authorities in India. Indian road safety situation is many times worse when compared to the developed countries of the world, leaving much to be done in the field of Road Safety Management. Road safety is defined as the absence of crashes, injuries, and fatalities. The term "safety" implies that there are no occurrences of accidents. The present study was conducted to identify the blackspot stretch on which Injury frequency and severity rate are more. Blackspot is a stretch of National Highway of about 500 m in Length in which either 5 road accidents (in all three years put together involving fatalities/ grievous injuries) took place during the last 3 calendar years or 10 fatalities (in all three years put together) took place during the last 3 calendar years. From the traffic survey, it was found that since 2015-2020 the area near MIET College is not safe for the riders. Statically Casualties occurred shows that 12 % cases related to Fatality, 38% cases related to Minor injury, and 50 % cases have been constituted for Major injury. MIET College area is located at Chainage 500+740 wherein it is located at the ‘At-Grade’ Intersection. In the present paper, the attempt is made to provide a practical Solution to rectify Blackspot. It includes providing Short-term and Long-Term Remedial Measures. Remedial measures suggested combating the fatalities with exponential scale and ensuring the safety of identified blackspots.

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.
