Authors: Pionar Rico Giyar , Prahara Eduardi , Nataadmadja Adelia Dwidarma 
Published: March 2022

Abstract
Transportation mobility is increasing every year and road infrastructure experiences increased loads. If the traffic load exceeds the planned load, premature damage can occur immediately and need more resources to maintain the damage. Therefore, Weigh in Motion (WIM)is needed to analyze the actual vehicle load on road infrastructure. The purpose of this study is to identify the Remaining Service Life and direct its maintenance patterns. By using WIM, the value of Remaining Service Life can be estimated. This paper presents the analysis result of the Weight in Motion data at Serang Barat Toll Gate in Indonesia and the impact on the Remaining Service Life. The axle loads were converted to represent single-axle loads based on 4th power formula by MDP 2017. The analysis showed that the CESA value obtained by using WIM data increased by 60.91% compared to the planned load and would cause a decrease in Remaining Service Life from the 20-year plan period to 16.82 years.

Abstract
Artesian well is one of the major efforts to obtain water source for fulfilling water demands in Eroniti Conservation park, Ponjong, Yogyakarta by drilling deep into several soil layers. Vertical Electrical Sounding (VES) method is the most common approach to determine the existence of groundwater. The method probes layers of rock below the ground surface based on their electrical properties, since the electrical resistivity of each layer is theoretically different. This study aims to utilize the VES approach for investigating the properties of the rock layers in the area to explore groundwater sources. We install six different VES points in the observation area using Schlumberger electrode configuration. The methodology of the work consists of three steps: the planning of the placement of the sounding points, the measurement step performed by a unit of IRIS SYSCAL Resistivity meter, and the data analysis and interpretation. Employing the resistivity analysis, we conclude that the observed region consists of Mediterranean soil as a result of weathering of limestone as well as lithology of the limestone. Furthermore, there are two types of aquifer found in the area: a perched aquifer found 27 meters below the ground surface of VES point 1 and a confined aquifer 166 meters below the ground surface of VES point 2 and 6.

Abstract
Weir is a building that is formed to change the nature of river flow to accommodate irrigation needs. The main purpose of a weir is to raise the river water level, drain the channel through the intake channel, allow water to be tapped, control all flow, etc. If a flow experiences a large shock, it will cause a hydraulic jump resulting in a transition of flow from supercritical to subcritical. The analysis can be performed, it was done using the Computational Fluids Dynamics (CFD) software, FLOW-3D. To model the 3-D weir used in this FLOW-3d, AutoCAD is used and finally, Flow Sight will be used to display visualization results such as graphics and videos. This paper investigates the Froude number and depth-averaged velocity on the trapezoidal weir. Moreover, the numerical modelling of trapezoidal weirs has been compared with the experimental result and numerical modelling of other types of weirs. The results show that the Froude number is proportional to the average velocity of this depth because the Froude number increases with the increase in the average velocity. There is a difference with the flow that flows after the weir, in a trapezoidal weir the Froude number decrease slightly but after that, it increases again downstream.

Authors: Suangga M. , Sularno  
Published: March 2022

Abstract
The truss bridge is a type of bridge that is widely used in Indonesia because of its practicality and can be constructed in short period of time. The relatively light weight of the truss bridge structure also facilitates the transportation of superstructure materials to bridge locations located in remote areas. The dimensions of the large truss bridge and the relatively light weight cause the figure bridge to be vulnerable to wind loads. Meanwhile, the bridge loading regulations including wind load is continuing to change. Previous design code BMS 1992 and SNI T 02 2005 has been superseded with SNI 1725 2016. One of the main changes to the loading regulations is related to the magnitude and how wind loads are calculated and applied to the bridge structure. This study will compare the magnitude of the wind load in the previous loading regulations in Indonesia with the latest regulations and also with wind loading according to AASHTO on steel truss bridges. A 60-class standard steel truss bridge from the Ministry of Public Works which is used for Case Study. The results showed that there was a significant increase in wind loading by applying SNI 1725 2016 loading regulations

Abstract
Landslides can damage public facilities and also have a negative impact on the community. This impact will be able to minimize when knowing the slope stability by carrying out the analysis to determine the factor of safety against landslide. The most accurate results usually get from calculation through computer software, but sometime it will take time and also not all of the designer have the sophisticated software. Another method in predicting the slope stability is using design chart as carried out in this study. The aim of this study is as a sustainable development of a simple chart to help the designer in predicting the landslide possibility. The graph will consist of the relationship between the slope height and the factor of safety for several soil strength parameter and slope angles. The slope stability analysis method will be based on LEM (Limit Equilibrium Method) through Bishop’s equation. The result is then being tested through case study and comparing with the other existing design chart and show a satisfactory result.

Published: March 2022

Abstract
Indonesia location is geographically very strategic for trade since it is located between two continents and two oceans. This condition must be supported by inter-island transportation facilities and infrastructure, including proper harbors. The ongoing construction of Tourism Harbor at South Eastern Bali must have satisfactory stability as an initial survey shows high passenger traffic. The tourism Harbor will connect the hinterland to the Nusa Penida Islands, specifically Sampalan, Buyuk, Toya Pakeh, Jungut Batu, Tanjung Sanghyang, and Munjul Bias.Therefore, analysis of piles subjected to lateral forces is critical to ensuring the stability and serviceability of a jetty structure. This study aims to investigate the structural stability of Tourism Harbor by analyzing the deflection of the pile with configurations such as pile diameter (35 cm, 45 cm, and 60 cm), pile materials (concrete pile and steel pile), and the berthing force caused by two types of passenger ships (Bounty Cruise and Bali Hai II) under extreme condition of HWS (2.6 m). The analysis results indicate that an insignificant deflection can be obtained by using a large diameter pile and installing steel piles.

Published: March 2022

AbstractIndonesia is one of the most populated and large country in south-east Asia. Its abundance of natural resources was well known. Supported by its tropical climate, made Indonesia is also among the largest tropical country in the world. However, according to the data, arable land in Indonesia has drastically decreased over the years in line with the rising demand for residency areas. This statistic shows a rather concerning fact that it is possible that even though Indonesia with this richness of natural resources one day would not fulfil its own domestic food needs. Moreover, competitions and hindrances that experienced by the Indonesian farmers might also worsen this limited food supply. In this research, the computational plant model (called virtual model) of the above-land Basil plant (Ocimum Basillicum P.) was proposed. The Basil plant that is taken as a research object is specific. It is a plant growing in a hydroponic environment. By using structural and functional plant model (FSPM) and simple mathematical and statistical methods, the constructed model was able to portray the growth pattern of each plant organ morphologically and biologically. The development and growth patterns of each plant organ (i.e., stem, petiole, leaves, etc.) are also depicted in detail and precisely. The model was quite novel. It practically can be exploited by agronomists and researchers to see the potential effort in optimizing the plant’s yield.

Abstract
Garbage is basically a material that is wasted or disposed of from a source resulting from human activities or natural processes that have no economic value, and can even have a negative value if it is not handled properly. Of the various kinds of waste that exist, one type of waste that can still be reused is plastic bottle waste. This study discusses the design and manufacture of a portable plastic bottle waste bank that provides sales value automatically through measuring the weight of plastic bottles using Arduino software. This plastic bottle waste bank tool is designed with the feature of automatic sales value acquisition through the acquisition of scale calibration data and determination of bottle categories measured using an IR sensor. The plastic bottle waste bank system is set using the Arduino Uno program to obtain the calibration factor from the load cell sensor. The test results show that the calibration factor with a value of 701 shows the smallest error percentage value and the average weight of the measuring stone is close to the actual value with the average data collection variable i in one experiment of 5. Testing on this waste bank tool is quite good because the tool able to provide categories and selling prices of plastic bottles based on a given programming function. However, this tool still lacks in the accuracy of calibration on the scales.

Published: March 2022

Abstract
The effectiveness and efficiency of the operation of oil palm plantations are considered to be the most crucial factor to develop the productivity and profitability of the palm oil business. One of the major obstacles for the plants to optimally produce crops based on their capacity is caused by the presence of noxious weeds in the plantation area. However, weed control via chemical processes may potentially harm the surrounding environment if it is not properly managed. Therefore, an automatic system to assist the farmers to identify and control the weeds is required to minimize harmful impacts on the environment. Machine Learning (ML) and Artificial Intelligence (AI)-based systems provide powerful tools to perform such tasks. In this work, we aim for an ML-based system design to perform an automatic weed recognition task. The methodology can provide an effort for environmental sustainability in oil palm plantations. The weed identification involves the description, the local names, and tolerance class of the weeds as well as suggestions to control them. The flow of this work consists of weed and herbicide data acquisition, data labeling, model configurations, and data training. Further, the proposed system can be adopted as an android-based application in mobile devices that can deploy the trained model to predict weed category in both real-time and non-real-time tasks.
