Abstract

The climate challenge is an energy challenge. thus, policymakers around the world are trying to accelerate the adoption of clean energy technologies. The Global Energy Review said that global CO2 emissions from energy combustion in 2021 reached the highest annual level with an increase of 6% from 2020, The automotive sector is very important to achieve net zero global emissions by 2050 based on the agreement with the world in the Scenario Net Zero Emissions by 2050. in which in 2035 sales of internal combustion engine cars (ICE) will be stopped. In this case, of course, electric vehicles are an alternative to the field of future land transportation that uses batteries as fuel that utilizes renewable energy as a charger for electric vehicles. Electric vehicle charging infrastructure (EVCI) is a key driver of increased electrification mobility shifting away from internal combustion engines given that the specific geographical distribution of a region and its demographics are factors influencing the adoption of electric vehicles. This paper was written to review the state-of-the-art of Battery Electric Vehicle (BEV), a PV energy source in terms of renewable energy utilization, energy generation, batteries, and charging stations. PV generation is extensively reviewed, and although this research is quite extensive, some gaps need to be investigated for further research on commercial and residential aspects as a means of operating batteries for electric vehicle charging stations based on PV and BESS (Battery Energy Storage System). Regulations on the use of battery electric vehicles as an environmentally friendly means of transportation will grow based on government policies from each country

Abstract

The rapid development of time has reduced the land used by farmers for farming due to development. For that, design a hydroponic system to minimize the land. Chili hydroponic plants are a type of vegetable that has many benefits and is liked by many people. So that hydroponic chili cultivators can produce optimal harvests, a tool is designed using automatic smart control technology using UV lamps. The findings in the field are that there are several steps that must be taken so that hydroponic plants can be more optimal in the results of chili cultivation. The first step is to design a smart plant control automatic tool, then use several sensors including EC sensors, ph sensors, RTC sensors, and ultraviolet lamps. An initial study of the potential benefits to be gained by partners or chili farmers based on the results of field testing is that this technology can maximize harvest time efficiency from manual hydroponic cultivation, which was originally 90 days to 70-80 days. Therefore, the automatic smart plant control system using UV lamps has a harvest speed of 70-80 days, while the manual method can reach 90 days. Thus, it is hoped that the economy of chili cultivators will increase if the smart plant control automatic system is used.

Abstract

In today’s climatic conditions such as unprecedented amounts of rain and frequent heat waves, cultivating has become a tedious task. Predicting nature’s next move is not easy but what we can do is minimize its effect on the yield. There are so many regions that receive excessive rainfall, suffer frequent flash floods and scorching heat. To adapt to these conditions, sensor networks can be deployed in the fields and the available resources should be used as efficiently as possible. In order to fulfill this requirement, power storage capable of storing energy efficiently from solar panels and an irrigation controller which monitors the land, be it for farm, gardening or horticulture with little to none intervention in certain aspects. The existing products in the market have proprietary parts, features and they don’t endorse cross-compatibility with other products. Keeping the design open source and easy to work promotes recycling and reparability something essential in the current time of global silicon shortage. Farmers or gardeners often don’t know the amount of water and the intervals of irrigation for many exotic and domestic species of plants, they then end up growing crops such as wheat and rice which need flooding of the field, the cultivation of these species can be promoted and be made easy with the project. Telemetry and connected technologies are part of every system these days. The project monitors various parameters and depending on the conditions, will carry out necessary action such as irrigation in only amounts required by the field. This is possible through PWM control of motors coupled with valves.

Abstract

Recent trends show that tubular systems are already popular for tall buildings in most regions of the world; the shear wall-frame system is also dominant in other parts of the globe. This study aimed to compare the dynamic earthquake behaviour of braced tube, diagrid, tube-in-tube, and shear wall-frame structures. This research study used ETABS software to model, analyze, and design 12 building models, whereby every structural system was comprised of 12-, 24-, and 36-story models. The constant model parameters were as follows: the floor slab depth and area, the service area, the plan dimensions, the story heights, and materiality. The research used modal response spectrum analysis per EN 1998-1-1:2004 for the Nairobi city area in Kenya to obtain the fundamental periods of vibration, top drifts, seismic base shears, and top floor accelerations of the braced tube, diagrid, tube-in-tube, and shear wall-frame models. The dynamic earthquake behaviour of the aforementioned lateral systems with different heights is illustrated. The study recommends the use of diagrid systems for seismic load resistance in 12-, 24-, and 36-story buildings with regular plan geometry. Keywords: Fundamental period of vibration, top drift, seismic base shear, top floor acceleration, modal response spectrum analysis, tall buildings.

Abstract

Evaluation of structural performance in Indonesia has been carried out for several high-rise buildings as part of the owner's demands for safety guarantees to determine the level of security that the building has. A simple but accurate nonlinear analysis is needed to determine the structure's performance under earthquake loads. The capacity spectrum method (pushover analysis) documented in ATC 40 is a form of equivalent linearization based on two basic assumptions: secant period and equivalent damping. The performance point estimates where the capacity of the structure can withstand a given (demand) load; In terms of performance, the level of damage to the structure category based on lateral displacement can be seen. It is simulated that an earthquake will shake the Klaten DPRD building with a magnitude of 7.0 and 20 km from the epicenter. The amount of PGA(g) will be calculated based on the equation of Cornell et al. Building structure modeling was carried out with the help of ETABS v9.7.4.

Abstract

Cofferdam is a building in the form of earth, stone, concrete or masonry filling and holds water, prevents flooding, provides irrigation. The building has many functions such as for agriculture, power generation, and tourist attractions. Cofferdam will also be very helpful in flood control which will control flood water so that it will not overflow excessively which endangers the surrounding community. Besides having great benefits. If the cofferdam collapses (broken) it will cause flash floods that result in casualties. Therefore the cofferdam must be designed safely and technically feasible. The research approach used in this study is a quantitative approach using the 2012 GEO-SLOPE program. The conclusions from the analysis of slope seepage and seepage stability are the Critical Safety Factors for cofferdam stability according to the results of the analysis after running SLOPE/W are 1.711 & 1.512 because it is higher than 1.5 (SNI 8460:2017 Geotechnical Requirements Design, This means that the stability of the cofferdam is safe. The modeling results show that the seepage discharge is 1.81x10-7 m3/s = 1.81x10-4 liters/sec = 15.64 liters/day which is smaller than the maximum allowable discharge of 50 liters/day. So it can be concluded that the seepage discharge is safe.
