Abstract
In the present paper, an analysis was carried out to optimize the cutting parameter i.e. speed in turning operation. The turning was done on a cylindrical rod with diameter and length of 35 mm and 300 mm respectively. The actual length of cutting was 100 mm. Five different cutting operations were taken place with five different cutting speeds i.e. 45, 105, 160, 270, 630 (in rpm) respectively. The surface roughness of the job and forces involved during cutting were measured through profilo-meter and dynamometer respectively. Also, the tool life was calculated by using Taylor’s tool life equation in each cutting condition. The elastic deflection of the tool in each cutting condition was simulated by using FUSION360 software. The optimum cutting speed was found out by applying multiple objective decision making (MADM) method.

Authors: Singh Harikesh , Singh Ashish Kumar , Hyderi Zakir Ali , Banerjee M.K. 
Published: April 2021

Abstract
In this paper precipitation behaviour of low carbon micro alloyed steel is seen by various heat treatment cycles at different temperature ranges. Precipitation occurs during the ageing cycles and as we can conclude from harness graph and microstructural study that precipitation of alloys like NbC, SiC, CrC, NiC, VC, MoC, BC precipitates on higher temperatures, therefore hardness tends to increase at some range of high temperature ageing. After their precipitation occurs there got a saturation in the system and again hardness tends to fall. Although the hardness result of all the samples do not show very significant difference, but as a whole the test shows rise, saturation and fall in hardness values which is due to various precipitation temperatures of various alloying elements involved.

Deep learning pre-trained model as feature extraction in facial recognition for identification of electronic identity cards by considering age progressing
Authors: Usgan M , Ferdiana R , Ardiyanto I 
Published: April 2021

Abstract
The usage of the face recognition system is various, one of which is to identify missing people. Cases of missing persons can usually happen to people who do not carry an identity card, such as people with mental disorders. Identity cards have some information, namely name, address, date of birth, and a photo ID of a face. This information has stored at the civil registry office, which is an Indonesian government agency. Therefore to solve this problem, we use a photo ID as a dataset to identify someone’s identity. Photo ID as a dataset has age progressing factors in facial recognition systems. Several previous studies have discussed age progressing factors. Previous research used MORPH, CACD, and FGNET datasets. The dataset has several photos of faces consisting of various age levels for the same subject, but it is different from the photo ID that we use. For the training data process, we only use one data, namely a photo ID used to recognize faces at this point. Therefore we use the pre-trained VGGFace2 model, and then, fine-tuning the data during the training process, we use AM-Softmax loss as a loss function. Then the classification is done using SVM. The method we use than compared with the Moustafa method, which also uses a pre-trained model. The results we obtained have a better accuracy performance of 0.9351 compared to the Moustafa method of 0.733

Abstract
Chemical Engineering Department, Gadjah Mada University, has a wastewater treatment plant to process wastewater produced by its laboratories. The WWTP consists of equalization, anaerobic, aerobic and phytoremediation ponds. WWTP operates with the adding of starch as substrate and NPK as nutrient. However this WWTP could not treat wastewater which contained a variety of chemical compounds, so that it did not operate properly. Therefore WWTP revitalization should be done in order to make it operate optimally. The purposes of the research are to determine the effect of Cr on the WWTP stability conditions, and the performance of aerobic activated sludge. The experiment was done by controlling substrates flow as much as 3 litters per day to the aerobic pond in a laboratory scale pond made from plastic with the capacity of 10 litters. The pond was run continuously, the samples of wastewater was taken to measure its BOD, COD, MLSS and MLVSS along with the waste feeding. The results showed that the higher Cr concentration the longer time required by aerobic bacteria to degrade it into Cr. Aerobic bacteria are able to reduce the BOD - COD of waste-water that contains Cr up to 50% on various concentrations.

Published: April 2021

Abstract
Information Technology and Information Systems are able to assist the performance appraisal process and assist decision-making by the management of an organization. Bank BTN Bogor Branch Office itself has carried out the performance appraisal process for employees every quarter, semester and annually every year. The performance appraisal process uses the key performance indicator method using several indicators, where the assessment is carried out by superiors to subordinates after a performance target has been set by the Central Bank BTN Office. The performance appraisal process takes quite a long time because the accountant has to collect every performance appraisal result from each work unit. In addition, the ongoing system has another weakness, namely that it cannot be monitored via the dashboard in real time by the Management division which aims to assist in decision making in finding top talent. This study designed a Management Information System for employee performance appraisal at Bank BTN Bogor Branch Office which is designed for 2 levels of management, namely middle level management and bottom level management. The design of this SIM includes 3 stages, namely the data collection method, the Rapid Application Development (RAD) system development method and the Service Oriented Architecture (SOA) method. The application of SOA is used so that communication between systems can run smoothly without being hindered by different platforms. The results of the SIM design in the form of a mockup that functions as an assessment system and monitoring media for employee performance with several features in it both mobile and website. Then there are several additional features in designing a mobile-based information system, namely employee performance which aims to see top talent candidate employees.
