Abstract

3D printing is an additive manufacturing method that turns digital design into an actual product. A 3D-printed part sometimes requires post-processing to enhance its physical and mechanical properties. Acetone vapor polishing is one of those techniques which is highly beneficial in smoothing ABS 3D-printed parts. Previously, an acetone vapor polishing device has been developed which uses a mist maker. However, for a more efficient polishing method, an optimized vapor polishing device using heat has been fabricated in this study. To assess the efficiency of this device, the researchers test the dimensional accuracy, surface roughness, tensile strength, and impact strength of polished and unpolished ABS 3D-printed specimens. The findings showed that the surface smoothness of the polished cube specimens did not significantly alter its physical geometry. The tensile test reveals that the overall elasticity of the polished tensile specimen has increased significantly while the impact test also shows that the polished specimens have the capacity to sustain a resistive impact from a swinging pendulum. Thus, all testing procedures indicated that post-processing using the optimized vapor polishing device has improved the overall physical and mechanical properties of the polished specimens.

Abstract

In the implementation of projects, various obstacles are often encountered which cause delays which have an impact not only on the duration of implementation but also on the costs incurred. These constraints can be in the form of a lack of resources, weather factors to social factors. Thus, it is necessary to accelerate and optimize what can be done to overcome the delay. As well as efficient resource management. One of the acceleration methods that can be used is the Crashing method. One of them is the application of the crashing method to the Ringinrejo - BTS road construction project. Regency. Malang STA 2+350 – 6+300 which experienced delays in its implementation. After analyzing the remaining work, the duration of the remaining work was 273 days or completed on December 31, 2022.

Abstract

Abstract. The sustainable management of the Miu watershed Basin is something that needs to be considered in line with the increasing complexity of environmental sustainability challenges and current water availability, not limited to maintaining the flow of water but need to pay attention to the balance of the ecosystem. Ecosystem conditions that are maintained influence high water absorption capacity, thereby reducing surface water runoff.. This research was conducted in the Miu watershed Basin with the aim of identifying the potential for water absorption, the method used in this study was a scoring method with four parameters, namely soil type, slope, rainfall, and land use. Data analysis was carried out using a Geographic Information System (GIS) approach. The results showed that the water absorption conditions in the Miu watershed Basin were classified as good (8.29%), normal good (73.91%), starting to be critical (14.51%), moderately critical (3.29%), and critical ( 0.00%).

Abstract

The government in carrying out its function as a public administration servant is regulated in law of the Republic of Indonesia number 25/2009 on public services. In this regulated about electronic government (e-government), many individuals use various web applications that require users to authenticate themselves to access each application. Many entities require various web- based applications for operational activities. This makes centralized access management for web-based applications very much needed. Currently, access management is often implemented using Single Sign On (SSO) with password authentication method. Security considerations arise against the use of passwords. This is because passwords have a vulnerability to brute forcing using a password list, and human nature often uses repeated or uncomplicated passwords. There is an alternative authentication method, namely Mutual TLS which utilizes Public Key Infrastructure (PKI). Users authenticate with X.509 digital certificates, so the authentication factor becomes something you have. This research aims to implement an integrated PKI SSO system and RBAC access automation. The approach of this project is research, design, implementation, and testing. The entire system is built with open-source software and implemented on a cloud infrastructure. The system has three subsystems, namely registration, login and RBAC access automation. All subsystems are tested according to the specified flow. The test results show that the registration subsystem has been successfully carried out as evidenced by the success of filling in personal data, approval flow, and downloading of certificates. The login subsystem was also successfully implemented, as evidenced by the existence of mTLS authentication with certificate validation. In testing the RBAC access automation subsystem, it is shown that the script created can perform access checks and access remediation if needed.

Abstract

A chatbot is a software that simulates human conversation through a text chat. Chatbot is a complex task and recent approaches to Indonesian chatbot have low accuracy and are slow because it needs high resources. Chatbots are expected to be fast and accurate especially in business settings so that they can increase customer satisfaction. However, the currently available approach for Indonesian chatbots only has low to medium accuracy and high response time. This research aims to build a fast and accurate chatbot by using Bag-of-Words and Deep-Learning approach applied to a car repair shop customer service. Sixteen different intents with a set of their possible queries were used as the training dataset. The approach for this chatbot is by using a text classification task where intents will be the target classes and the queries are the text to classify. The chatbot response then is based on the recognized intent. The deep learning model for the text classification was built by using Keras and the chatbot application was built using the Flask framework in Python. Results showed that the model is capable of giving 100% accuracy in predicting users’ intents so that the chatbot can give the appropriate responses and the response time is near zero milliseconds. This result implies that developers who aim to build fast and accurate chatbot software can use the combination of bag-of-words and deep-learning approaches. Several suggestions are presented to increase the probability of the chatbot’s success when released to the general public.

Abstract

Radiotherapy is the treatment of cancer by using electromagnetic and particle radiation. Nasopharyngeal Cancer (NPC) is one of the difficult case to be treated in radiotherapy because its anatomical location. Precision of radiation dose is part of Quality Assurance Program as the key factor in this treatment. Thus, it is very important to ensure that the output dose of Linear Accelerator (LINAC) matched with result of Treatment Planning System (TPS). This study used Siemens LINAC Type Primus MACH Series 5633 and a set of detectors for Nasopharynx Cancer analysis with 8 field. The total dose of 5,000 cGy divided into 25 fractions with 200 cGy dose per fraction. The 8 fields are irradiated with a target on a detector device. It is then accumulated with PTW-Verisoft software by plotting the results obtained from the detector tool with PTW (phantom) which we have CT Scanned first in PTW-Verisoft. From the total detectors exposed to the radiation, the detector corresponding to PTW is 372 detectors (100%) with unsuitable detector of 0 detectors (0.00%). It is proved that the planning is 100% match for NPC with 8 fields of radiation. Thus, this method is recomended to be implemented for NPC treatment
