Mining in the world consists of modern and traditional mining. Various studies have discussed how field workers were precarious at being exposed to Covid-19 in modern mining. Many studies discuss ways of modern mines overcoming Covid-19, but discussion of research related to the impacts of Covid-19 on traditional mining has not been carried out. This study addressed the effect of the Covid-19 pandemic on traditional oil mining in Wonocolo, Bojonegoro Regency. This work is a descriptive study using observation and in-depth interviews and reviewing secondary data related to conventional mining activities. The results showed that the Covid-19 pandemic has an indirect effect on traditional oil mining activities in Wonocolo. The pandemic caused a decrease in demand, a drop in selling prices, lower production, and temporary closure of wells in Wonocolo traditional mining. In contrast, Covid-19 did not directly affect miners' activities since the miners believed that Covid-19 could not infect them due to the very extreme condition in the mining area that the Coronavirus would not survive.

Climate change affects the thermal performance of buildings. A building's thermal performance is influenced by its envelopes, such as roof, wall, and floor. A different building envelope may create a different thermal condition which may also influence its occupants' comfort. This research aims at analyzing the residential thermal performance at the tropical highland areas by examining the deviation between the outer and inner space's air temperature and humidity. The research employed a quantitative method by measuring the air temperature and humidity for 24 hours which were recorded every one hour. There were 15 houses with various building envelope materials as the samples. Since highland has colder air temperature, the differences between thermal variables of the outer and inner space's of the residentials were observed to figure out the longest warming. The warming process is associated with the occupants' thermal comfort standards. The results showed there are two types of residential producing the longest warming (23 hours) which in accordance with the occupants' thermal comfort standards. The first type is the house enveloped with roof tiles, wooden walls, and an earthen floor, while the second one is a residential house enveloped with a zinc roof, exposed stone walls, and an earthen floor.

Macular pigments produced from microalga Chlorella sp. and applied to alleviate the pathogenic process in diabetic mice

引用

Algal Research 2024年 78卷

作者： Meng-Wei Lin Wei-Hong Chiu Cheng-Han Lin Dung-Huan Liu Pei-Ching Wu Chih-Sheng Lin Department of Biological Science and Technology National Yang Ming Chiao Tung University Hsinchu 30068 Taiwan Doctoral Degree Program of Biomedical Science and Engineering College of Biological Science and Technology National Yang Ming Chiao Tung University Hsinchu 30068 Taiwan Department of Physical Medicine and Rehabilitation China Medical University Hospital Taichung 404 Taiwan Department of Chinese Medicine China Medical University Hospital Taichung 404 Taiwan

Macular pigments (MP), which consist of lutein and zeaxanthin, have antioxidant capabilities and are widely used in eye healthcare. However, few studies have focused on the protective mechanisms of MP against diabetes mellitus. In addition, the advantages of MP produced by microalgae include non-competition with grains for land, year-round harvesting, and rapid growth. Therefore, this study aims to investigate the MP produced and extracted from the microalga Chlorella sp. AT1 and assess its impact on mitigating retinopathy and atherosclerotic damage in diabetic apolipoprotein E -deficient mice (ApoE −/− ) subjected to high-fat diet and streptozotocin treatment. The results showed that the major components of MP were lutein and zeaxanthin in a 5:1 ratio. MP supplementation significantly reduced glucose tolerance and insulin resistance by 25 and 41 %, respectively, in comparison to the diabetic group. MP supplementation resulted in the moderation of various inflammatory cytokines and lowered the serum levels of disease markers in comparison to the control group. In addition, the expression levels of cellular antioxidant enzymes were significantly elevated, aligning with a reduction in lipid peroxidation after MP supplementation, in comparison to the diabetic group. Pathological changes in the outer nuclear layer and aortic plaques in diabetic ApoE −/− mice were significantly alleviated by MP supplementation. In summary, microalgal MP alleviated the symptoms of type 2 diabetes mellitus in the diabetic ApoE −/− mice. Consequently, MP holds the potential to serve as a beneficial ingredient in healthy food, contributing to biological efficacy by scavenging free radicals and stabilizing blood glucose levels.

The effect of muffler mounting to the engine noise of LAPAN surveillance UAV - 02 (LSU-02)

引用

AIP Conference Proceedings 2023年第1期2941卷

作者： Agus Bayu Utama Aries Asrianto Ramadian Siswo Hadi Sumantri Romie Oktovianus Bura Gita Amperiawan Research Center of Aeronautics Technology National Research and Innovation Agency (BRIN) Jakarta Indonesia Doctoral Program of Defence Science Republic of Indonesia Defense University Jakarta Indonesia Faculty of Defence Technology Republic of Indonesia Defense University Jakarta Indonesia Faculty of Mechanical and Aerospace Engineering Bandung Institute of Technology (ITB) Bandung Indonesia

The effect of muffler mounting on LAPAN Surveillance UAV-02 (LSU-02) engine noise has been investigated. In the propulsion laboratory, the LSU-02 engine was tested by varying the throttle setting so that the propeller rotated with RPM variation. The noise level was measured by using noise sensor, located 1 meter behind the engine and 1 meter front the engine. The same test was repeated, but this time the engine had a muffler. The maximum noise level for the LSU-02 engine was 113.9 dB without a muffler and 98.7 dB with a muffler, with noise sensor located 1 meter behind the engine, at the highest propeller rotational speed of 6500 RPM, according to the measurement results. The engine noise level was reduced by an average of 15% and 12% with noise sensors mounted behind and in front of the engine. With current muffler design and operation by propeller speed of 5000 RPM, the measured noise level could not be suppressed to under 85 dB.

Quantum annealing for vehicle routing problem with weighted segment

引用

AIP Conference Proceedings 2023年第1期2906卷

作者： Toufan Diansyah Tambunan Andriyan Bayu Suksmono Ian Joseph Matheus Edward Rahmat Mulyawan Doctoral Program of Electrical Engineering and Informatics School of Electrical Engineering and Informatics Institut Teknologi Bandung. Jl. Ganesha 10 Bandung 40132 Jawa Barat Indonesia School of Applied Science Telkom University. Jl.

Quantum annealing technologies aim to solve combinatorial optimization and sampling problems. Studies on combi-natorial optimization problems include the selection of vehicle routes on road traffic, known as the NP-hard problem. We propose a vehicle route problem that can be formulated in the Quadratic Unconstrained Binary Optimization (QUBO) model as a combina-torial problem to optimize vehicle route selection. The solution aims to optimize the vehicle’s journey to reach a destination. The experiment presents a formulation to solve traffic congestion problems on certain roads. The selection of vehicle routes results in optimizing the distribution of alternative road vehicle flows. The level of road density is a cost function that will be optimized, and the constraint is a limitation on the route choice for each vehicle. This vehicle routing problem considers the weight parameter (as distance in actual road conditions) of the road segment that affects the cost function. The simulations on the D-Wave quantum annealer show optimal results on the route deployment of several vehicles. The cost value on route choice with weighted segments gives better results than in previous studies. Each vehicle can go through different road options and accurately reduce road conges-tion. This solution provides an opportunity to develop QUBO modeling on more complex vehicle routing problems to reduce road congestion.
