Abstract

The purpose of this community service in the form of training is to improve the ability of functional planner staff in forecasting indicator targets of regional performance. This training is the continuation of (i) the training of using parametric statistic to increase the motivation of North Lombok Regency Bappeda's functional planner staff in research and scientific publications and (ii) the training of data processing using minitab for functional planner staff. This training was held on December 9, 2022, in BAPPEDA office in North Lombok Regency. The training participants were 6 functional planner staff. The method used in this training is providing a pre test, material deliverying, followed by practical forecasting of one of the regional performance indicators and ended with a post test. The material contains the definition of forecasting and several forecasting methods suitable for limited time series data including the Moving Average (MA) method, Simple Exponential Smoothing (SES) and the Naïve method, while the post test included the questions about the material given and the practice, also asked for suggestions, criticisms and themes for the further training. The effectiveness of the training will be tested with Wilcoxon Match Pairs test. The results of this training is the participants felt very helpful and proposed several themes for the next training. The results of the Wilcoxon Match Pairs test show that is greater than , meaning that the average post-test score is significantly higher than the average pre-test value or, in other words, community service in the form of training has an effect on the forecasting abilities of functional planner staff at North Lombok Regency's BAPPEDAThe purpose of this community service in the form of training is to improve the ability of functional planner staff in forecasting indicator targets of regional performance.

Abstract

A bank is a financial institution that plays an important role in fulfilling and providing various financial services to customers. The increase in the number of customers and service time leads to queuing, especially at the teller section, thereby affecting waiting times. This article discusses customer queues at the teller service of Bank R in West Nusa Tenggara Province (NTB). Queues arise when service demand exceeds available capacity, causing customers to wait due to limited teller services. This study aims to analyze the optimization of the queuing system at teller services using the Multi-Channel Single-Phase queuing model. This model features multiple entry lines into the service system but only one service facility. The results show that the service intensity level () from Monday to Friday is , , , , and , respectively. Since , the steady-state condition is met. Thus, the queuing system performance can be considered optimal.
