Perancangan Aplikasi Pemesanan Tiket Wisata di Kecamatan Donorojo Menggunakan Metode Payment Gateway

Currently, the process of ordering tourist tickets is still done manually, especially in the Donorojo area, namely by visiting a travel agent or contacting the relevant party by telephone to order tickets. This process tends to take a long time, especially if users must queue to place an order. In addition, information regarding ticket prices and available schedules is not always easily accessible to users. The impact of this problem is confusion and errors in ordering tickets, as well as the buildup of queues at counters which causes congestion. To overcome this problem, we developed a tourist ticket booking application in Donorojo sub-district by implementing payment gateway methods including Flutter as a mobile application development framework and Firebase as a database management system that allows users to order tickets online, find out available tourist destination information and prices. and the schedule of tickets offered. The solution step taken is to collect and analyze data regarding popular tourist destinations, as well as implementing an online payment feature in the application. The interim results we have obtained are applications that are able to provide information about available tourist destinations, as well as provide convenience in the payment process and increase transaction security by using this payment gateway. Users can choose the desired destination, select the date and number of tickets needed, and make payment via the application. After payment is complete, the application will issue an electronic ticket which can be shown upon arrival at the tourist destination.

Optimalisasi Pelayanan Publik Bidang Administrasi dalam Pembayaran Tagihan Perusahaan Daerah Air Mineral (PDAM) (Studi di Kantor Pos Delivery Center Sekejati Kota Bandung)

Public service is an absolute thing that happens in human social life. This makes public services one of the aspects that must be considered in governance for the purpose of creating satisfaction in the process of social interaction. One of the institutions that has not been able to provide maximum public services to the community is the Sekejati Post Office, Bandung City. The Sekejati Post Office in Bandung City provides several services to the community, one of which is the PDAM bill payment service. In the service process for paying PDAM bills, it was found that there are still service support facilities that have been unable to operate properly. This study aims to determine how to provide bill payment services for PDAM Post Office Sekejati Delivery Center Bandung City. The research process was carried out using qualitative research methods where in-depth interviews and observation methods carried out the data collection process. From the research that has been done, it was found that the obstacles that occur in the process of optimising the PDAM bill payment service at the Sekejati Post Office in Bandung City are systems that often have errors and there is a buildup of queues when one of the counter officers is unable to attend due to health reasons.

Qualitative research: Utilization of the mobile application of national health insurance (JKN) to increase the effectiveness of services

Background: Sundari General Hospital has implemented an online registration system as a solution to the problem of patient backlogs. Patient registration via the national health insurance mobile (M-JKN) application at Sundari General Hospital has yet to reach the set target.Purpose: To analyze patient registration through the national health insurance mobile application at Sundari General Hospital.Method: Qualitative research uses a case study approach. The research was conducted from April to July 2023. The informants in the study were 10 people. The research instrument uses a list of questions as an interview guide. The information-gathering process was carried out using in-depth interviews, observation and documentation.Results: Showed that the input component has been running well, but there are still some obstacles, such as training for officers, inadequate patient infrastructure, and socialization to patients. The patient registration process has been carried out according to the SOP, but there are still many patients who need help understanding the use of the M-JKN application. The output component needs to be optimized due to the low participation of patients who register through the M-JKN application.Conclusion: Patient registration via the national health insurance mobile application at Sundari General Hospital has been going well, although there are still obstacles, and utilization is still low. However, it has been quite effective in reducing the buildup of patient queues.

Overcoming The Buildup of Queues By Carrying Out the Concept of Self-Service Using Responsive Web-Based Applications

This food and beverage menu self-order system was created with the aim of making it easier for waiters and customers in the ordering process. With this system, waiters no longer need to record food menus manually, and customers can also order menus directly through the system without having to queue. Before designing the system, an analysis is carried out first, this system will later be designed in the form of a responsive website and designed using the PHP programming language and MySQL which is used as a database storage. That way it is hoped that the design of this application can help restaurants in the process of ordering food and collecting order data.

Analysis of risk management of online queue innovation system services (SINOVA) Bantul Regency

Public governance is a concept that describes the government's ability to fulfill people's satisfaction and achieve people's prosperity. Currently, the government is required to improve risk management to deal with various challenges that come quickly, uncertainly, and minimize the possibility that they will occur in the future. One form of risk management is through Governance, Risk, and Control (GRC). The Disdukcapil of Bantul Regency issued a website-based service that is expected to be able to provide convenience for the people of Bantul who experience problems in processing population documents. This article aims to understand and describe the application of risk management principles carried out by the Disdukcapil of Bantul Regency during the COVID-19 pandemic using a qualitative approach using the case study method. The results showed that risk management carried out through website-based services had not been fully responded to by the community, so Disdukcapil delegated tasks by opening Adminduk services in sub-districts. This is in response to reducing queue buildup during the Covid-19 pandemic.

Implementasi Sistem Pemesanan Menu Di Kafe Dan Resto Sunny Bangkinang Menggunakan Qr Code Berbasis Website Menggunakan Framework Codeigniter

Currently, ordering menus at Sunny cafes and restaurants is still manual. Ordering menus that are still manual creates a problem, namely when the customer has finished selecting a menu, the customer does not know the total price of the order. Customers who come together at the same time will cause a buildup of order queues. From these problems, we get a solution by building a menu ordering system using a website-based QR Code using the PHP programming language, the CodeIgniter Framework, MySQL as a database and using UML (Unified Modeling Language) as a design. The purpose of making this system is so that customers can easily get information on menu catalogs and prices without having to ask the waiter. A menu ordering system at Sunny cafes and restaurants using QR codes has been successfully created.

Optimizing Data Transport Efficiency in Datacenters through Traffic Shaping of BBR Congestion Control

Compared to commonly used loss-based congestion control algorithms predominantly used in Transmission Control Protocol (TCP) implementations, congestion-based congestion control called BBR has shown much better performance in resource-abundant modern communication links. However, for a high influx of TCP sessions on the bottleneck switch, clusters in High-Performance Compute (HPC) nodes and data centers face resource constraints because of the immense workload during orchestration and relocation of workflows across the resource pool. This article discusses how to resolve this problem, commonly known as TCP incast, through efficient queue management of the bottleneck link and adding a shaper function in the standard BBR algorithm. We analyzed TCP incast issue for two efficient versions of congestion control i.e., BBR and CUBIC (named after the cubic function used instead of linear function), in a highly overloaded convergent switch of the cluster. It is noticeable that the queuing delay and buffer build-up are two essential parameters in causing TCP Incast. Hence, we used the M/G/1/B queuing model when multiple TCP sessions generate the network traffic and different buffer build-up scenarios are analyzed in the bottleneck node of HPC clusters. Based on the findings of our queuing analysis, we propose an incast recovery BBR algorithm that introduces additional controls like Incast shaping to deal with queue build-up during TCP incast. The effects of these modifications in BBR implementation are studied in terms of performance parameters like flow completion time, throughput, RTT variations, and fairness to other competing flows are significant compared with standard BBR and CUBIC implementations.

Analysis and Evaluation of Fully TCP-Compatible Backpressure-Driven Traffic Engineering

Throughput optimality is a core objective for the operation of modern networks. The backpressure routing and scheduling scheme is well-known for being analytically-optimal in terms of throughput maximization. Its operation is driven by packet queue build-ups at the network nodes, and constant status updates among neighbors in order to deduce the best next packet forwarding step. However, this operating principle is also incompatible to TCP, which uses congestion control to avoid queue build-ups. These factors have so far limited the use of backpressure at the edge only. The present work presents a novel combination of TCP and backpressure at the network layer, overcoming any compatibility issues and allowing for backpressure to be active at all network nodes without exceptions. The key idea is to apply the Lyapunov framework cumulatively, over a large set of router hardware clock ticks. This approach allows for the throughput-optimal backpressure decisions to be expressed via regular traffic engineering routing rules, instead of explicit per-packet forwarding directives. Simulation results validate the analytical findings, and demonstrate significant throughput gains over state-of-the-art related approaches. Proof of concept emulations showcase the simplicity in the implementation of the proposed scheme.

Protocol-Based Congestion Management for Advanced Air Mobility

Advanced air mobility operations are expected to significantly increase the demand for limited airspace resources. Two key features distinguish advanced air mobility operations from commercial aviation. First, unlike commercial aviation, where flight schedules are set months in advance, advanced air mobility demand is dynamic (i.e., flights are planned with a much shorter lead-time). Thus, operators benefit from planning in shorter time horizons and can confidently share their desired flight trajectories only for the near future. In addition, operators may be unwilling to share estimates of the full trajectory, for competitive reasons. The second key feature is the large-scale of operations. Thus, a centralized optimization approach may not scale to meet the expected levels of demand, and it offers no redundancy against communication failures. In this paper, we address these challenges by designing a protocol that determines the “rules-of-the-road” for airspace access. Our protocol centers on the construction of priority queues to determine access to each congested volume of airspace. We leverage the concepts of backpressure (measure of queue buildup) and cycle detection (vehicles that block each other from proceeding) to promote efficiency, and present several flight- and operator-level prioritization schemes. In the absence of actual demand data, we study three scenarios: random origin–destination missions, crossflow traffic patterns, and simulated hub-based package delivery operations. We evaluate our protocols on two performance measures: efficiency (i.e., magnitudes of delays) and fairness (i.e., equitable distribution of delay across flights and operators).

Evaluasi Penerapan Sistem Informasi Manajemen Rumah Sakit (SIMRS) Menggunakan Model Human Organization and Technology Fit (Studi Kasus : Rumah Sakit Arsani – Sungailiat Kabupaten Bangka)

Abstract — Arsani Hospital has been implementing HMIS since 2010 to support operations to improve service and limprove work effectiveness and efficiency. But in its appication, there are obstacles such as the low use of HMIS, the lack of employee knowledge in using HMIS, HMIS display is difficult to understand, HMIS has not been integrated (BPJS system, attendance and employee payrol) and there is a buildup of queues in the administrative process. So that the evaluation of the implementation of HMIS quantitatively uses the HOT-Fit (Human Organizational and Technology Fit) model that focuses on three dimensions, namely human (system development, user satisfaction, system use), organization (organizational structure, organizational environment), and technology (system quality, information quality, service quality). This study aims to find out the factors that affect the success rate of HMIS implementation at Arsani Hospital using questionnaires where a total of 99 respondents obtained by PLS-SEM data analysis using SmartPLS v3.3 software. The results showed that of the 18 hypotheses developed, 1 hypotheses were accepted while the other l7 hypotheses were rejected. So that the output of this study is given several recommendations that are intended to increase the success rate of HMIS mplementation in Arsani Hospital.

Penerapan Optical Character Recognition Proses Registrasi Pasien Tes Covid-19 Berbasis Web

Covid-19 cases in Bali in the period October to November 2020 experienced an increase which could cause hospitals to experience an increase in demand for health services. Hospitals are one of the most important departments during the Covid-19 pandemic. As a health service agency, the hospital must provide quality services to all levels of society who visit. In realizing optimal public health services, hospitals need a system that supports services to the community. In carrying out the Covid-19 test, the patient registers at the admission, the Nakes (Health Personnel) enters the patient's identity manually using the Microsoft Excel application. In the registration process, there are often discrepancies in the patient's name, date of birth, address and telephone number as well as other identities due to input errors. The large number of patients who register to do the Covid-19 test makes the Nakes (Health Personnel) take a long time, the time required to collect the data is 10 minutes and results in a queue buildup. To overcome this, applying Optical Character Recognition (OCR) can make it easier for Nakes (Health Personnel) to register and input KTP / KIS data automatically, thereby reducing patient data collection errors. Seeing this problem, from this research, a website was built by applying Optical Character Recognition (OCR) and the development method used was the Waterfall method and the suitability of the system built was tested using the black box testing method. This system gets a percentage of 79.4% which means both from admin and doctor respondents, and gets a percentage of 92.8% which means very good from user respondents (patients).

Queue-Aware Access Prioritization for Massive Machine-Type Communication

One of the pivotal services of the fifth generation (5G) of cellular technology is massive Machine-type Communications (mMTCs), which is intended to support connecting high density of machine-type devices (MTDs). Random access channel of long-term evolution (LTE)/LTE advanced needs to be modified in order to support the large simultaneous arrival of MTDs. 3GPP suggested access class barring (ACB) as a mechanism to inhibit network congestion in the mMTC or massive Internet of Things (IoT) scenario. Consequently, in devices that are repeatedly ignored by ACB, the queue of data packets keeps growing. In storage-constrained IoT nodes with limited buffer, this may lead to packet drop due to buffer overflow, causing a decline in the overall throughput of the system. To address this issue, a novel queue-aware prioritized access classification (QPAC)-based ACB technique is proposed in this article, where MTDs having data queue size close to its buffer limit are dynamically given higher priority in ACB. To study the queue build-up at each MTC device, a node-centric analysis of ACB in the buffer-constrained scenario is performed using a 2-D Markov chain. It is shown that the proposed QPAC scheme, with optimal model parameters obtained by maximizing overall system utility, offers up to 70% gain in throughput compared to the nearest competitive dynamic ACB scheme.

Studi Simulasi Sistem Pada Perusahaan Jasa Pengiriman Barang dan Ekspedisi

Currently, the competition of delivery service providers is increasing. Companies must strive to improve customer service and satisfaction to survive in this competition. One of the service improvements relates to the queuing system. This research was conducted at the counter of a logistics company, which provides delivery and expedition services, located in Cikarang, Bekasi. There was often a build-up of queues at counters and accumulated goods to be packaged. As a result, officers have very high utilization, because they should serve the customers; meanwhile, they also have to do packing works. This study uses a simulation approach to analyse and improve the performance of the current queuing system. Simulations are carried out using Promodel in the delivery handling system, namely starting when the customer enters the store, handling customer needs (including in the case of packing the goods until the service is complete and the customer leaves the store. There are two suggestions for improvement; short-term and medium-term improvement proposals for the short-term focus on customer service (excluding packaging), namely by providing registration forms and also preparing a refund that can shorten the service process. Meanwhile, the long-term improvement is to strengthen the service system with an additional information system, standardization of processes and costs, as well as extra officers who specialize in packing. The simulation results show that short and medium-term improvement can reduce waiting time and utilization, and increase the number of goods packed.

Quality Analysis of E-government Services Using SERVQUAL Method (Case Study of SAMSAT Office in Kolaka Regency)

This study discusses the measurement of the quality of motor vehicle tax of information system services at the SAMSAT Kolaka office using the servqual method by emphasizing the five dimensions of servqual namely Tangibles, Reliability, Responsiveness, Assurance and empathy. This study aims to understand the level of user satisfaction by comparing expectations and expectations and updating the standards provided by SAMSAT Kolaka through the application of the SIZ application. Data collection activities were carried out by distributing 100 questionnaires to all SIZ service users. The results of this study indicate that the use of SIZ is not by customer needs; this can be demonstrated by the high value of the gap between expectations and perceptions. The Assurance dimension obtaining the most top difference is the Tangibles dimension indicating that the limitations of the IT facilities used are still limited. It is evidenced by the continued complaints of customers regarding queue buildup due to a system that suddenly goes down while the service is in progress. It is necessary to improve IT infrastructure that can improve customer satisfaction in the future.

Penerapan Algoritma Dynamic Priority Scheduling pada Antrian Pencucian Mobil

Queue is a condition where the number of service recipients is higher than the number ofservice providers. This condition can cause a buildup of service recipients, and eventually,bottlenecks will occur. It faced by all service organizations that focus on service to customers.No exception is a car wash business whose business processes focus on providing fast andquality car wash services. But unfortunately, many car wash businesses get complaints fromcustomers, especially related to the queue buildup and unclear queue information received bycustomers. Therefore this study aims to produce a mobile-based car wash queue application,which includes a dynamic priority scheduling algorithm that functions as a queue manager.To carry out these objectives, a research methodology that is sequential and iterative used,namely, the software development methodology using the Rapid Application Development(RAD) model. This model consists of four phases: planning needs, prototype development,system development, and finally, testing. The Application test is finished with two approaches,namely testing of application code, specifically the application of dynamic priority schedulingalgorithm and testing of the overall functional system. From the test results, it knows that thecar wash queue application managed to sort customer orders based on the specified priorityrules based on the distance and time of the law. While the results of testing the systemfunctionality show that the application successfully manages a variety of errors, both causedby system failures and due to human error.

Observing and Mitigating Micro-Burst Traffic in Data Center Networks

Micro-burst traffic is not uncommon in data centers. It can cause packet dropping, which may result in serious performance degradation (e.g., Incast problem). However, current approaches to mitigate micro-burst is usually ad-hoc and not based on a principled understanding of the underlying behaviors. On the other hand, traditional studies focus on traffic burstiness in a single flow, while micro-burst traffic in the data centers could occur with highly fan-in communication pattern, and its dynamic behavior is still unclear. To this end, in this paper, we re-examine the micro-burst traffic in typical data center scenarios. We find that the evolution of micro-burst is determined by both TCP’s self-clocking mechanism and congestion control algorithm. Besides, dynamic behaviors of micro-burst under various scenarios can all be described by the time derivative of queue length evolution.Our observations also implicate that conventional solutions like absorbing and pacing are ineffective to mitigate micro-burst traffic.Instead, senders need to rapidly respond to some explicit signals of the queue buildup caused by the micro-burst traffic rather than independently and ineffectually pacing themselves in isolation. Inspired by the findings and insights from experimental observations, we propose Micro-burst-Aware Transport Control Protocol (MATCP), which leverages characteristic behaviors of micro-burst traffic derived from the time derivative of the queue occupancy. MATCP can suppress the sharp queue length increment by over $2\times $ and reduce the tail query completion time by up to 84.4%.

Optimization of Healthy Service by Implementing the System Queues on Social Insurance Administration Organization (BPJS) in Dr. H. Marzoeki Mahdi Hospital in Bogor

Patient queue buildup on Social Insurance Administration Organization (BPJS) in the Dr. H. Marzoeki Mahdi hospital (RSMM) in Bogor is a problem that often occurs. This is caused by the patient's arrival rate exceeds the service facilities provided. To reduce the buildup of queues and improve services, queueing M/M/S model is applied in BPJS patient. M/M/S model is used so that the Ministry can optimize the management system as well as reduce queues at the BPJS patients patient service (TPP) in Bogor RSMM. On-site system queues on the TPP can be done at a time when the number of staff service (counter) at least 5 officers of service so that in addition to be able to reduce the chance of a busy period of previous service officer can also optimize on-site services, but for the wait and cost expenditures costs of facilities not significant therefore need to add 1 more Ministry officials became 6 officer's service in order to improve the facilities of the Ministry on patients as well as patients BPJS TPP not too long to wait in the process the queue.
