Design alternative on peat soil
Authors: Muroby Vicky , Anwar Makarim Chaidir 
Published: December 2020

Abstract
Construction on peat soil has its own difficulty and challenge due to its properties of low shear strength, high compressibility, high water content, and flammable material. Indonesia ranked 4th on peat land area around the world after Canada, Russia, and United States. Based on recent mapping, peat land covers 14,9 million hectare in Indonesia. This paper presents the finding from literature studies regarding peat soil, construction on peat soil, case studies for road infrastructure construction on peat soil at West Borneo, Indonesia, and provide analysis and recommendation for the problems faced. Construction on peat soil requires special attention, especially on the design and execution. In the event where construction must be performed on a peatland which thickness is < 3m, the approach recommended is peat removal and replacement. If the peat thickness is 3-10 m, adopt the preloading, construction with vertical and sand drain, lightweight fills, surface mattress, stone column, etc. If the peat thickness is < 10m, use pile as foundation. Unit price contract is preferable over lumpsum contract due to the high uncertainties of peat soil. Environment impact due to construction on peat soil need to be accounted for, also the risk of peat fires need to be considered if dewatering used.

New Relationship between Linear Shrinkage and Shrinkage Limit for Expansive Soils
Authors: Widjaja B , Chriswandi C 
Published: December 2020

Abstract
In Indonesia’s engineering practice, a standard laboratory test method to describe the characteristics of expansive soils is the shrinkage limit (ASTM). Expansive soils are problematic soils that have shrinkage and swelling history due to changing water content on a particular clay mineral type (i.e., montmorillonite). Another method rare using in general practice in our country is the linear shrinkage (British Standard). The last test is easier and faster to obtain than the shrinkage limit method. Some researchers proposed swelling potential classification for expansive soils using a specific range of shrinkage limits or linear shrinkage. This research aims to give a new relationship between both methods using available laboratory test results database. There were two sets of data: first, complete laboratory data (i.e., 124 samples of shrinkage limit and linear shrinkage); and second, only Atterberg limits (i.e., liquid limit and plastic limit) results (i.e., 86 samples). For the latter database, shrinkage limit and linear shrinkage use previous researchers’ empirical equations. Then, these two datasets are compared and give a similar trend. The results show that if increasing of shrinkage limit is followed by decreasing of linear shrinkage. This result may help geotechnical engineers to obtain the linear shrinkage directly from our proposed Equation and shrinkage limit value. Hence, our research has a contribution to know the characteristics of the expansive soil (i.e., swelling potential).

Abstract
It was noted that the existence of house fires caused by gas stoves is still large. Gas stoves are common devices in Indonesian household. However, they have some drawbacks that can cause house fires. This causes the need for technological improvements in gas stoves to minimize this possibility. The implemented secured automatic gas stove uses a gas solenoid valve to automatically turn it on/off and can be monitored through an Android smartphone using Wi-Fi transmission, i.e. based on the Internet of Things, which is a value-added solution to gas stoves. The system also has a motion sensor to minimize the occurrence of negligence when cooking. This information will be sent and displayed on the Android application of user’s smartphone. Warning will be given through the application so that user can act properly and immediately when getting it. Testing results were as follows. At first, the gas sensor could detect gas leak if it had passed the value of 300 ppm. Second, Android application could display information about the status whether gas stove turned on or off, and it could be turned off by pressing a button on it. At last, solenoid valve was successful in stopping the flow of gas from the gas cylinder. All functions of the overall system could work well as expected in the design stage.

Published: December 2020

Abstract
The Vehicle stability is the major concern in the high speed car being produced now a day. The fuel consumption is mainly affected by different forces which include the force due to drag and lift, force due to self-weight, side forces and also the thrust acting on the vehicle. About 60% of the drag is which is caused due to the relative motion between the air and the vehicle is created at the rear end. The fuel consumption can be increased by reducing the drag force at the rear end. So this paper aims to reduce the drag force which helps in improving the fuel consumption which leads to environment protection. We used a Sedan car with various types of spoilers for reducing the aerodynamic drag force. The design of the car was done on SOLIDWORKS and also it was used for the analysis in SOLIDWORKS FLOW SIMULATION. The analysis was done to find out the drag and lift forces at various velocities and by using different spoilers. This study proposed a numerical model which was effective when done on the computational fluid dynamics (CFD) so as to obtain the different flow structure around the car with spoiler at the rear end.

Published: December 2020

Abstract
The demand for increase in performance of the manufacturing units is increasing day by day. This project work aims at improving the Overall Equipment Effectiveness (OEE) of a Hardinge 600 II series Vertical Machining Centre (VMC) machine by modification of its subsystems. The problems related to higher power consumption and decreases in the units produced per unit hour were taken for analysis. By analyzing the earlier conditions it was found that the productivity of the VMC machine was found to be limited because of low OEE. The installation of an accumulator in the hydraulic system of work holding device and a simplification of the chip removal mechanism was proposed on the VMC subsystem. Also these changes were only possible to be done effectively by removing the existing conveyer belt and introducing tray disposal system. After the suggested changes were made the machine was again investigated to check for any possible increase in the OEE. An increase of 40% in OEE was achieved after implementation of the suggested changes. The improvement in OEE could be followed in similar machines such as HMC machines, FMS setups and other machines through proper steps for better productivity of the manufacturing facility.
