Authors: Desvita H , Faisal M , Mahidin M , Suhendrayatna S 
Published: March 2021

Abstract
Cacao pod shells (Theobroma cacao L) form biomass waste that can be used as raw material for liquid smoke because this biomass contains lignin, cellulose, and hemicellulose. This research studied the antimicrobial activity of liquid smoke from cacao pod shells on several common food-borne pathogens, such as Salmonella choleraesuis, Escherichia coli, Staphylococcus aureus, and Bacillus subtilis. The liquid smoke used was obtained from cacao pod shells that were pyrolyzed at 300 °C (T1), 340 °C (T2), and 380 °C (T3). Liquid smoke concentration varied from 1% to 5%. The antbacterial activity test was conducted using the Kirby–Bauer method. The results showed that liquid smoke produced from T1 and T2 (and at liquid smoke concentrations of 4% and 5%) could inhibit the growth of all the tested bacteria. At T3 and 1–5% of liquid smoke, only E. coli was consistently inhibited (inhibition zone = 6–7.05 mm), while the growth of S. choleraesuis and S. aureus was inhibited at 3–5% liquid smoke with the inhibition zone ranging from 6 mm to 7.2 mm. B. subtilis was inhibited by a 2–5% liquid smoke concentration. All the tested bacteria showed sensitivity to liquid smoke, but E. coli was the stronger resistant compared to others. The results of this study show that liquid smoke from cacao pod shells could be used as a preservative agent to inhibit microorganisms in food.

Authors: Nicodemus A M , Latief Y 
Published: March 2021

Abstract
Occupational, Health, and Safety (OHS) issues in Indonesia are still often overlooked. It appears that the number of work accidents is still high. Therefore, in early 2018 the government has decided to suspend all the elevated construction projects in Indonesia including Flyover Project. It causes negative impacts such as casualties, material, time, cost, etc. Two factors that most hinder OHS implementation in the project based on the contractor’s point of view are the high cost of OHS implementation and the safety cost provided for OHS implementation by the owner is inadequate or even none at all. Safety cost planning can be done accurately if the activities based on the Work Breakdown Structure (WBS) on the project can be well defined. The Activity-Based Costing method provides more accurate information especially on complex structures while can provide information on cost items. This study aimed to identify the OHS cost component of the Flyover Project based on standardized Work Breakdown Structure in erection girders application using the tandem crane, which is supported with archival analysis, expert judgment, and survey to obtain a decent budget and specifically allocated for the implementation of OHS to improve working safety conditions.

Published: March 2021

Abstract
Construction built on soft soils will cause several geotechnical problems, one of which is a consolidation settlement that lasts for a long time due to the low permeability of soft soils. This study aims to compare the time of soft soil consolidation settlement before and after soil improvement using Prefabricated Vertical Drain (PVD). PVD is a plastic sheet made from a composite, consisting of a drain core and filter jacket with a function to accelerate the process of pore water discharge to the ground surface by shortening the horizontal waterway. The method used using analysis, where the time of consolidation settlement reaches a degree of consolidation of 90%. The PVD pattern used is a triangle pattern and a rectangular pattern with a distance variation of 0.6 m; 0.7 m; 0.8 m; 0.9 m; 1.0 m; 1.1 m; and 1.2 m. The results obtained, based on the PVD pattern, the time of consolidation settlement is faster if using a triangle pattern compared to the rectangular pattern. Whereas, based on distance, the smaller the distance between PVDs, the faster the time of consolidation will decrease.
The effect of soft clay improvement using Prefabricated Vertical Drain (PVD) for rigid pavement structure
Authors: Syahril S 
Published: March 2021

Abstract
Rigid pavement is widely used in subgrade conditions that have low bearing capacity so that it will affect the life of the road plan and rigid pavement performance. Soil improvement that can be done is by using Prefabricated Vertical Drain (PVD). Soil consolidation with plate load test is carried out to get the modulus of subgrade reaction. Modulus of subgrade reaction without PVD is 2179,24 kN/m2/m and with PVD distance of 100 mm is 11311,09 kN/m2/m. The modulus of the verified subgrade reaction without PVD is 22419,21 kN/m2/m and with PVD is 38718,40 kN/m2/m. The thickness of the analyzed plates are respectively of 150 mm, 200 mm, 250 mm, 300 mm, and 350 mm. The position of the vehicle wheel load is in the middle, the end, and the edge. The deflections due to the position at the middle, the end, and the edge loads respectively for the entire plate thickness are reduced by an average value of 31%, 34%, and 33%. Rigid pavement performance based on the modulus of subgrade reaction and deflection caused by MST 10 ton vehicle loads with a 1.2 axis configuration shows that soil improvement using PVD can increase the modulus of subgrade reaction and reduce deflection values.

Published: March 2021

Abstract
The development of the internet of things has penetrated in several lines, including in agriculture. To respond to the development of this IoT requires rapid technological adaptation as well. To build a system quickly, one can utilize the Rapid Application Development (RAD) method. RAD is a model that allows non-experts to benefit from high-performance computing, while allowing expert programmers to take full advantage of the underlying hardware. This enables rapid prototyping, retargeting, and reuse of existing software, while allowing hardware-specific optimization if needed. The RAD system emphasizes the fast development cycle that is designed and high-quality results from other methods such as waterfall, agile, scrum and others. The system was built using the minimum NodeMCU system with the help of a soil moisture sensor. The use of the RAD method in building an IoT-based agricultural irrigation system gives good results in testing all functions and equipment controls. The average delay level on testing IoT devices is around 4.6 seconds so that the RAD method can be used as a reference in the construction of an IoT-based system.

The imbalance between each development of a technology not accompanied by development in the security system itself. As for the current problem is that there are still state website that are still working with outside companies in terms of network security systems. And most often the target of cyber attacks is the web server. Then any individual or organization is required to have a security system that minimizes of cyber crime. Instead of putting trust in an outside company I better make my own web server security system. The author uses the application gateway method in a firewall. Besides, firewall failover capabilities are evaluated. Based on the overall testing results, application gateway has better performance than other types of firewalls in another website. It has better ability in handling DoS attack, because this firewall works not only based on the secure, destination and attribute of the package, but can reach the contents of the package. It is conclu1ded that application gateway is suitable and safe to use on TNI AD web server.

Abstract
In this modern world, the use of artificial intelligence needed. One of the intelligence methods raised in this study is to use the Interval Type-1-Fuzzy Inference System (IT-1-FIS). In Muslim schools (Madrasah Ibtidaiyah) where there is subject matter memorizing the Qur’an. The fluency determines the quality of memorization of the Qur’an in pronouncing letters (Input-1), Tajweed Rules (Input-2), and reading fluency (Input-3). These three points become input for forecasting Memorization Quality Of The Qur’an. IT-1-FIS requires primary inputs and rules to obtain the output of forecasting Memorization Quality Of The Qur’an. By using IT-1-FIS, it can predict that students will get the quality of memorization based on the trace value obtained on each point. So from the beginning the teacher will know the quality of a student’s memorization in the future. The estimated condition in memorization of the Qur’an can be known faster, and the teacher will be able to increase the points that are less to get the desired quality of memorization of the Qur’an by the habits practiced by students. These students’ patterns are the basic rules of input in the IT-1-FIS process.

Published: March 2021

Abstract
English is an international language that dominates in almost every sector of human activity. Despite learning English as a foreign language from elementary school, Indonesian students still face difficulties in speaking and writing correct English even during their higher levels of education. Researchers claim that traditional English teaching methods have failed to motivate students to keep constant attention. As a result of less engagement in the learning process at an early stage, students end up facing understanding issues. This study aims to introduce a mixed method of teaching tenses in English grammar. This combined teaching approach focuses on increasing motivation, performance, and developing a competitive mentality among students. The method applied is using smart multimedia along with gamification in an informal cooperative learning group. The findings indicated that using gamification and smart multimedia in an informal cooperative learning group increases student performance, motivation, and gives satisfaction to students in the learning process.
