Abstract

This study aims to determine sales strategies for cassava chips through a dynamic simulation approach using iThink software. The simulation is used to model the factors influencing sales performance, such as fluctuations in raw material prices, operational costs, and market demand patterns. By employing a CLD (Causal Loop Diagram) model and dynamic simulation, this research evaluates various strategies, including product diversification, digital promotion, and distribution efficiency. The simulation results indicate that implementing strategies such as flavor variant diversification and increased promotion through social media can significantly improve sales and profits. Validation was carried out through sensitivity testing on cost and sales parameter changes, demonstrating that dynamic simulation can be an effective tool to support data-driven strategic decision-making

Abstract

Sertifikasi merupakan bisnis kepercayaan sehingga hubungan antara pemberi jasa yakni Lembaga Penialaian Kesesuaian atau LPK dengan pelanggannya menjadi sangat istimewa. Kepuasan pelanggan adalah salah satu faktor penting yang terus dijaga dan dievaluasi dari waktu ke waktu. Perusahaan mitra Registra Indonesia adalah salah satu LPK dengan skala usaha kecil menengah memiliki komitmen untuk memelihara kepuasan pelanggannya, sehingga bersama dengan tim pengabdian masyarakat dari Universitas Pakuan telah membangun suatu sistem penilaian. Sistem penilaian kepuasan pelanggan dibangun berbasis sistem informasi yang terintegrasi dengan web sites Registra Indonesia. Sistem penilaian kepuasan pelanggan LPK Regista Indonesia telah diuji coba pada semester II tahun 2023, melalui pengumpulan pendapat dari 22 pelanggannya melalui GForm. Hasil analisis menggunakan metoda Importance Performance Analysis menunjukkan bahwa tingkat kepuasan pelanggan rata-rata 90.77% dari harapannya. Sehingga Wilcoxon Signed-Rank Test memastikan bahwa kepuasan pelanggan telah sesuai dengan harapannya.Seluruh factor penentu kepuasan pelanggan yang dievaluasi pada Semester II Tahun 2023 menunjukkan tingkat kepuasan Sangat Baik. Sementara evaluasi yang dilakukan berdasarkan jenis produk layanan menunjukkan posisi juga Sangat Baik, kecuali sertifikasi HACCP yang satu tingkat di bawahnya yakni Baik.

Abstract

In everyday life, queues often occur. Waiting at the counter to get train or movie tickets, at the toll gate, at the bank, at the supermarket, and in other situations that we often encounter Queues occur when the need for services exceeds the capacity or capacity of the service facility. As a result, users of the facility cannot get immediate service due to the busyness of the service. The Amplas Toll Gate queue is the object of this research. The Amplas Toll Gate is one of the densest toll gates that is heavily traveled by vehicles both entering and exiting. This makes it often seen a fairly long queue, especially during peak hours in the late afternoon to evening. The Medan City Government built an off ramp at the Amplas flyover in 2016. This off ramp leads directly to the Amplas toll gate. The vehicle arrival rate increases along with the queue length because vehicles can arrive faster to the toll gate. This study aims to calculate the queue length at the Amplas toll gate before and after the construction of the ramp off. Data is obtained by recording the volume of vehicles at the research location. With an average service time of 7 seconds, the queuing method produces a queue length of 11.98 meters, while the results using Pro Model software are 11.98 meters. In addition, the queue length after the construction of the ramp off decreased to 6.67 meters from before the construction of the ramp off. Promodel is a windows-based simulation software used to simulate and analyze a system.
