Abstract

Sorting goods based on the results of checking packaging labels is an important process in controlling production quality in industry. Many industries still carry out manual sorting and label checking processes, which results in low productivity levels and is susceptible to human error. This research develops an automation system for sorting goods based on label inspection using vision sensors, programmable logic controller (PLC), and robot arm. The system controlled by a PLC will read and detect damage to packaging labels by using VeriSens vision sensor and sort them using a robot arm according to predetermined stock keeping unit (SKU) categories, namely SKU 1, SKU 2, SKU 3, SKU 4, and rejected goods. The pneumatic system is used as an actuator to push goods onto the conveyor, moving the robot arm with three degrees of freedom and vacuum. Detection is carried out by applying the edge detection concept to read text, images and code that are reprocessed with the VeriSens Application Suite software. The success rate of the goods sorting system reached 90% with a reading speed of 0.389 seconds and a work process duration ranging from 21.54 seconds to 28.99 seconds.

Abstract

The development of information technology cannot be separated from the use of mobile applications, which are increasingly varied. Mobile applications allow users to easily connect to internet services anywhere. Cooperatives are joint business entities that generally still use the manual method for recording members, transactions and so on, which can lead to human errors and time inefficiencies. The existence of a website-based cooperative mobile application that is implemented on smartphones using the Xamarin.Forms framework can reduce these problems. Smartphones will make online cooperatives more effective because they are portable, easy to use and more affordable.

Abstract

A battery is a device that stores power in an Uninterruptible Power Supply (UPS) system. The most common type of UPS battery found today is Valve Regulated Lead Acid (VRLA). So that the UPS can work optimally according to its capacity and backup time, it is necessary to determine the battery capacity. In this research, the capacity of the VRLA battery on a particular UPS was determined based on direct testing and based on calculations. VRLA battery capacity calculations refer to the UPS and battery datasheet. The calculation stage starts from calculating the current and battery power used according to the load power absorbed by the UPS and referring to the table of constant current discharge and constant power discharge characteristics. Determining battery capacity based on testing is done by measuring the backup time of the UPS. The calculation results and test results directly show that there is a difference in backup time because the battery used is an old stock battery. The research results also prove that determining battery capacity by calculation can ensure that the battery capacity is more appropriate or not too large so it is more economical.

Abstract

Technological developments make it possible to monitor electricity consumption in real-time via the internet. The system developed uses a power meter to collect data, Python to process data and IoT connectivity via NodeMCU ESP8266 to send data to the internet. Python is used so that measurement data can be processed and presented in an easy-to-understand format. The test results show that electrical data measurements can be displayed with an error ranging from 0.04% -11.56%. This is because there is a delay from the time the power meter is measured until the data is displayed on ThingSpeak.

Abstract

The increasing reliance on real-time services such as VoIP and video streaming underscores the critical role of fiber optic networks as high-capacity communication backbones. While optical fibers offer substantial bandwidth, this alone does not ensure optimal Quality of Experience (QoE); network delay and jitter remain prominent challenges that can disrupt audio clarity and video continuity. This paper presents a detailed analysis of delay and jitter phenomena within fiber optic systems, particularly emphasizing Passive Optical Network (PON) topologies. It explores the underlying causes of performance degradation from physical-layer limitations to architectural inefficiencies and critically assesses current mitigation techniques implemented at both the network level (e.g., Quality of Service mechanisms) and application level (e.g., jitter buffering strategies). The main contribution of this work is the introduction of a novel "Cross-Layer Performance Optimization Framework," which addresses the disconnect between static QoS enforcement and reactive application adaptations. By fostering dynamic interaction between the network and application layers, this framework aims to enable predictive control mechanisms that better safeguard user experience. Ultimately, this approach offers a pathway to more robust and efficient delivery of real-time services over next-generation optical access networks.
