Abstract

Danangshoop is an online store that focuses on agriculture and sells plant seeds. On its journey, Danangshoop encountered a problem in its e-commerce system, specifically the unsequential arrangement of products in the best-selling column. This research are meant to change the sequence of best-selling products in order according to the total number of purchases per product. Market Basket Analysis is the method used to analyze consumer purchasing patterns, and the results are the basis for marketing strategies that enhance sales targets. The implementation of Market Basket Analysis helps in designing promotions and product placements intelligently. This research uses a quantitative approach, analyzing data by calculating confidence and support values. The lift analysis results indicate that a combination of vegetable seeds and fruit seedlings has the most significant impact on the purchase of vegetable seeds. The conclusion highlights a variety of products, especially vegetable seeds that are in demand among consumers. The store can enhance promotions by featuring vegetable seed products in the "best-selling products" menu, as vegetable seeds are the most purchased products based on previous research. Additionally, another option is to offer combined purchase packages. These recommendations are expected to boost the sales of vegetable seeds at Danangshoop.

Abstract

This study analyzes the queuing system for motorcycle fuel filling at a gas station in Cilegon city using discrete simulation. The gas station often faces long queues that cause inconvenience and decrease operational efficiency. The research method includes collecting primary data through direct observation to obtain information on the number of vehicle arrivals, service time, and the number of operating booths. Secondary data is obtained from the literature related to queuing systems. After the data is collected, distribution analysis is conducted to understand the arrival and service patterns. A simulation model is created and tested using Arena Software. Model verification and validation ensure the accuracy of the simulation results. The research findings show that in the initial model, 54 vehicles were served in 50 minutes with an average waiting time of 45.9506 seconds. The first improvement scenario added one operator to each server, while the second scenario added a new server with two operators. The second scenario provided the best results with 106 vehicles served in 50 minutes and the waiting time reduced to 31.6773 seconds, showing a significant increase in system efficiency. The percentage increase in the number of vehicles served is approximately 96.30%, while the waiting time decreased by 31.06%. The implementation of the second scenario is expected to reduce queues and improve customer satisfaction and operational efficiency at the gas station. Keywords: Arena, Gas Station, Queue, Simulation

Abstract

Permintaan tiket konser yang tinggi sering kali mengakibatkan antrian panjang dan waktu tunggu yang lama bagi para penggemar. Fenomena ini tidak hanya menyebabkan ketidaknyamanan bagi para pembeli tiket tetapi juga menimbulkan tantangan logistik bagi penyelenggara konser. Dalam era digital, sistem distribusi tiket telah beralih dari metode tradisional ke platform online yang lebih efisien. Namun, peralihan ini membawa tantangan baru, termasuk masalah kapasitas server, keadilan distribusi tiket, serta ancaman dari bot dan calo tiket. Penelitian ini bertujuan untuk menganalisis dan membandingkan efektivitas sistem penukaran tiket online dengan metode penukaran langsung (OTS) dalam hal waktu tunggu dan waktu layanan. Penelitian ini menggunakan pendekatan Discrete Event Simulation (DES). Data yang digunakan adalah data antrian pada konser dengan langkah-langkah yaitu langkah Pertama adalah melakukan studi pendahuluan, langkah kedua adalah melibatkan pengumpulan data, langkah ketiga yaitu melakukan pengambilan sampel data, langkah keempat yaitu mengolah data, langkah kelima validasi lalu merusmuskan kesimpulan. Temuan menunjukkan bahwa metode penukaran tiket online lebih efektif dibandingkan dengan metode OTS, dengan rata-rata waktu layanan untuk metode online sebesar 616.269 detik dibandingkan dengan 15.248 detik untuk metode OTS. Ini menunjukkan peningkatan efisiensi waktu layanan sebesar 24.742% dan pengurangan waktu tunggu sebesar 3.898% menggunakan metode online dibandingkan dengan OTS. Hasil ini menyarankan bahwa metode online dapat dijadikan referensi bagi penyelenggara acara konser untuk menerapkan sistem penukaran tiket online.

Abstract

The purpose of this study is to assess the level of crowding in service in restaurants in Cilegon City and to propose improvements to the queue system based on the appropriate queue model for the restaurant. The method used is the Discrete Event Simulation (DES) method. The simulation approach allows for an in-depth and direct analysis of the system over a period of time, providing a realistic picture of the situation on the ground.  The data used in this study is primary data, including customer arrival time data and service time (server) data measured using a stopwatch. The results of the study showed that there was a queue with an average of 10 people and a server busyness rate  of 99.32%. This high level of busyness can result in a decrease in customer satisfaction due to long waiting times. Based on the results of the two scenarios tested, namely scenario one with the addition of 1 server and scenario two with the addition of 2 servers, the first scenario involving the addition of one server/cashier was chosen because it succeeded in reducing the number of customers with a busy level of 70.68%.

Abstract

Poverty is defined as a state in which individuals or groups of people are unable to exercise their basic rights to lead a dignified life. One of the cities in Indonesia is Serang City, located in the province of Banten. Currently, the poverty rate in Serang City has reached as high as 46 thousand households, with 8,799 of them falling into the category of extreme poverty. Based on the data obtained, the poverty line in 2022 is higher than the poverty line in the period 2020-2021. This poverty is due to several main factors, including low education, low income, and a lack of job opportunities. Therefore, this research aims to understand the causes and effects of poverty in Serang City and how to address it. To model the poverty alleviation efforts in Serang City, researchers use the Causal Loop Diagram (CLD) method. Causal Loop Diagram (CLD) is a visual tool used to model and analyze the cause-and-effect relationships between various factors in a system. The data processing results reveal the causes and effects of poverty in Serang City, including unemployment, low education levels, increased mortality rates, crime, limited job opportunities, and restricted healthcare services.

Abstract

Queueing issues at an ice cream parlor in Serang City have led to long lines due to having only one service system. The queue problem arises when many customers request service, but the number of servers is limited. One issue is that customers often have to wait in line to be served by the cashier. The aim of this study is to develop strategies to reduce queue length and improve service efficiency. The method used is Discrete Event Simulation, which provides a reliable and measurable approach to model queue variations. This system allows for identifying the best solutions to reduce waiting time and increase service efficiency in the ice cream parlor industry. This study shows that with 30 data replications and using seconds as the time unit, the total queue waiting time is 7,215 seconds with an average of 510.59 seconds. The average waiting number in the queue is 2.2371. The result of 0.95 indicates that resource utilization is close to maximum (close to 1), meaning the resource is almost always in use.

Abstract

Dengan menggunakan algoritma Apriori, penelitian ini mencoba menemukan pola penjualan produk di kantin kampus. Algoritma ini dipilih karena kemampuannya dalam menemukan hubungan antar produk berdasarkan aturan tertentu yang dihasilkan dari data transaksi. Data yang digunakan dalam penelitian ini berasal dari 200 transaksi penjualan yang terjadi selama satu minggu, yang mencakup berbagai jenis makanan dan minuman. Analisis dimulai dengan membuat satu set itemset dan kemudian menggabungkan itemset hingga menemukan aturan asosiasi yang memenuhi nilai minimum dukungan dan kepercayaan. Hasil penelitian menunjukkan terdapat tiga aturan asosiasi yang memenuhi kriteria dukungan minimal 30% dan keyakinan minimal 80%. Beberapa aturan yang dihasilkan antara lain: jika Anda membeli nasi bakar, kemungkinan besar Anda akan membeli usus bakar dengan keyakinan 82%, dan jika Anda membeli nasi bakar, kemungkinan besar Anda akan membeli bakso bakar dengan keyakinan 81%. Aturan lainnya adalah jika Anda membeli usus bakar, kemungkinan besar Anda akan membeli bakso bakar dengan tingkat kepercayaan 87%. Temuan ini diharapkan dapat memberikan rekomendasi strategis bagi kantin kampus dalam pengelolaan stok dan tata letak produk, sehingga dapat meningkatkan efisiensi pengelolaan persediaan dan memaksimalkan keuntungan. Oleh karena itu, penelitian ini menunjukkan bahwa algoritma Apriori dapat digunakan dengan baik untuk menganalisis pola penjualan dan membantu bisnis membuat keputusan berbasis data.
