Publisher : Universitas Pendidikan Indonesia (UPI)

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.

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.

Eco-Friendly Concrete Innovation in Civil Engineering Zahra Ghinaya; Alias Masek
ASEAN Journal of Science and Engineering Vol 1, No 3 (2021): AJSE: December 2021
Publisher : Universitas Pendidikan Indonesia (UPI)

Recently, the weather changes that have occurred are very unconditioned. This feels natural because it has often been felt, even though the heat that occurs is beyond its limit. This is one of the effects of global warming. Concrete is one of the most widely used materials in construction. In fact, cement production is included in the less environmentally friendly category. The purpose of this study is to find out how research on green concrete and whether it has an impact in the world of civil engineering. This research is using a quantitative method. This research describes only a few of the results of trials conducted by several researchers in the world, which prove that there is environmentally friendly concrete that can be applied and some are not. The results of this study showed that most of the innovation of green concrete is not good enough to be applied in the field. This is because in several studies it has been proven that the mixture in the manufacture of green concrete does not qualify as an aggregate material. The conclusion is that there is no innovation in the manufacture of green concrete that has worked so as not to cause damage to the earth. Therefore, other research on green concrete is very necessary to do.

Comparative Study on Extraction of Humic Acid from Pakistani Coal Samples by Oxidizing the Samples with Hydrogen Peroxide Muhammad Asif
ASEAN Journal of Science and Engineering Vol 2, No 1 (2022): AJSE: March 2022
Publisher : Universitas Pendidikan Indonesia (UPI)

Humic Acid is soil conditioning agent, which is used for improving the soil chemistry, plant root growth and related metabolism. Pakistan is an agricultural country and about 70% of population is directly or indirectly linked to the agricultural sector. Coal is considered one of the most appropriate raw materials for humic acid. The yield of extracted humic acid from coal is inversely proportional to the rank of coal. Since, majority of Pakistani coals are of low rank, extraction of humic acid from indigenous coal may be one of the non-fuels uses of coal. Three different coal sample from Thar, Dukki and Chamalong coalfields were treated with 3% H2O2 solution for determining the impact of oxidation on humic acid yield. The yield of humic acid from H2O2 treated samples were as follows; 2.5% for Chamalong coal sample, 16.5% from Dukki, and 35% from Thar coal sample. Thar coal sample, being the lowest in rank among all experimented coal samples, yielded higher fraction of humic acid.

Population of the world is increasing very rapidly, due to which energy demand is also is increasing unfortunately Pakistan has deficiency of petroleum of reservoir. Pakistan is producing about 64% of its primary energy from fossil fuel which has serious burden on its economy. At the same Pakistan has been blessed by bio-energy production from different types of biomass waste, jatropha is a wild plant which can at any type of land like in Thar, Thal, Cholistan, and other barren land zones. Sample of jatropha raw oil was collected from local market and it was converted into bio-diesel by transesterification process. Purified jatropha oil was used to produced bio-diesel by Transesterification method, Due to transesterification being reversible, excess alcohol is used to shift the equilibrium towards the product. This project can be started in bellow 10 million capital cost and operating cost is about 0.6 million per month. According to our calculation the bio-diesel production cost will be approximately less than Rs. 30 per liter. If the government and concern department focused on the production of jatropha plant and bio-diesel production by jatropha, it will great contribution in saving import expenditures.

Spatial-temporal and Factors Influencing the Distribution of Biodiversity: A Review Girma Gizachew
ASEAN Journal of Science and Engineering Vol 2, No 3 (2022): AJSE: December 2022
Publisher : Universitas Pendidikan Indonesia (UPI)

Ecosystem health and the accomplishment of the Sustainable Development Goals require biodiversity. However, the causes of biodiversity loss, as well as regional differences in their repercussions, remain poorly understood. We focused on the regional and temporal aspects that influence biodiversity distribution. Though transportable data is rarely convenient for providing accurate images of the proportions and distribution of all components of various ecosystems, there are certain patterns and strategies that call producers will employ to obtain useful assumptions of both terrestrial and marine ecosystems. The purpose of this term paper is to conduct systematic reviews to reflect the biodiversity distribution of different spatial and temporal dimensions in the biodiversity of plant species, animal species, microorganisms, and ecosystem diversity and the factors affecting biodiversity. Biodiversity is best defined by the patterns of the world around us, and these patterns are the source for understanding biodiversity. The distribution of biodiversity is uniform and inconsistent around the world. Therefore, the shift from the equator to the poles reduced biodiversity. These show that, unlike temperate regions, the tropics have more solar energy, water availability, and a relatively constant and predictable environment. The distribution of biodiversity is affected by a variety of environmental factors, including regional geological history, environmental stability, ecosystem productivity, habitat heterogeneity and suitability, competition, and predation. Therefore, understanding the spatial and temporal distribution of biodiversity is urgently needed to develop short-term and long-term resource management strategies, and biodiversity education and training activities are innovative.

ASEAN Journal of Science and Engineering Vol 1, No 3 (2021): AJSE: December 2021
Publisher : Universitas Pendidikan Indonesia (UPI)

This research is intended to determine the optimum combination of parameters and how much the contribution of the parameters of cutting speed, oxygen gas pressure, and nozzle distance to the width of the cutting kerf. This research was conducted with a method, namely Taguchi Design of Experiments (DoEs) by varying the process factors used in the AISI 1045 steel material cutting process. The control factors in this study consisted of three factors, namely cutting speed, gas pressure, and tip distance. The cutting speed and cutting gas pressure are significant factors in the optimization of the AISI 1045 steel cutting process for minimum kerf width with a contribution of 95.6%, while the tip / nozzle height factor is not significant in the optimization of the AISI 1045 steel cutting process for the kerf width minimum. The optimum parameter values to obtain the minimum kerf width in AISI 1045 steel are cutting speed of 250 mm/min, gas pressure of 3 kgf/cm2, and tip height of 4 mm. Furthermore, the results of the verification tests carried out indicated that the optimal process parameter formula obtained is feasible to use, indicated by the S / N ratio and confidence interval (CI) of prediction and verification that coincide with one another. The optimal process parameter formula can be used as a reference for industrial production activities with a 95% success rate.

Publisher : Universitas Pendidikan Indonesia (UPI)

The number of COVID-19 corpses is highly increased since 2020. This situation tends to risk the health workers directly interacting with COVID-19 victims during the burial process. In Indonesia, the conventional method of burial process requires four to eight health workers. Thus, minimizing the number of involved health workers is needed. This paper aims to propose a bed-stretcher that assists the burial process of the COVID-19 corpses efficiently. Hence, the number of people involved can be minimized. The design considers a maximum weight of 2000 N of the coffin, which includes the corpse inside. The device is equipped with a shaft-pulley system, gear, and ratchet mechanism to lower the coffin inside the grave. The strength analysis of the shaft-pulley system by theoretical approach is conducted under static and fatigue loading conditions to estimate the service life. As a result, the calculated safety factor demonstrates a value of more than one, indicating the structure is safe under both static and fatigue loading conditions. Moreover, the device can be operated only by two health workers. In addition, this work is expected to contribute to the innovative idea of engineering products to overcome the Pandemic of COVID-19.
