Abstract

The development of time and technology significantly impacts business competition. Companies strive to produce high-quality products to remain competitive. It is crucial to control the products they produce to achieve this goal. This is something that PT Z, as a company that consistently maintains the quality of its products and prioritizes customer satisfaction, should already be doing. However, in 2022, it was noted that one of their products, strawberry powder, experienced a decline in quality. This was evidenced by records from the quality control department and complaints from consumers, citing damaged labels, leaking packaging, and differences in color and taste compared to expectations. In light of these issues, this research aims to further analyze the root causes of defects using the seven tools method and provide recommendations for improvement in the form of the 5W + 1H to PT Z, to prevent similar defects from occurring in the future. Based on the analysis, it was found that the causes of defects are attributed to human factors, machinery, materials, environment, and methods used.

Abstract

Transformation of production and service processes is a form of change in the industrial revolution era that is supported by systems. One of the components in a company's information system is a web page or known as a website. User Interface in website design is a concern at the CV X company which operates in the interior contracting sector. This research aims to redesign the user interface to suit user needs on the CV X website using the design thinking method. The design thinking method has six stages, namely, empathize, define, ideate, prototype, test, and implement. This research carried out four of the six stages of design thinking. Several research results include a collection of companies' desires to change the layout, content and elements on the website, content regarding SVLK, the use of persuasive words, and navigation features in the website footer that are not yet available in the current design. Defining the problem at the define stage is the elimination of be spoke pages, the use of colors that match the characteristics of the company, the addition of interactive animations, and changes to all elements on the website. The results of collecting ideas at the ideate stage were 9 ideas. The realization of ideas at the prototype stage consists of 3 processes, namely the style guideline creation process, the redesign process, and a comparison of the current design with the redesign results. The process of creating a style guideline includes fonts, colors, button elements, website headers and footers. This research focuses on the website user interface only so that the test and implementation stages related to User Experience (UX) are not analyzed.

Abstract

KRM ice cream shop is a popular destination in Sanur, Bali. The intensity of customer visits on regular days is already quite crowded, even more so during the holiday season. Due to the location of Gerai KRM which is adjacent to the road sidewalk, it often causes congestion in the area. The long and less conducive queuing system is the main reason customers discourage coming. This research was conducted during peak hour, namely 11:00 to 13:00 which is lunch time. These data are then tested using the Stat::Fit feature to determine the type of data distribution. This type of data distribution will later be used to determine the length of the system process when tested in ProModel software, more precisely it will be included in the processing sequences section. The research results show that there is an entity of customers in waiting of 6.13% and blocked by 10.10% which is caused by a lack of capacity and service units in the system. Based on the problem, the proposed improvements given by the author are the addition of cashier units and also the queue capacity at the Ice Cream storefront service. The output of the proposed system simulation is a decrease in the percentage of blocked 1.32%. Then the percentage of full in the queue row which became 0% and the percentage of full in the ice cream storefront was reduced to 1.71%.

Abstract

The construction industry and infrastructure development are crucial aspects of a country's economic advancement, with cement being a key primary material. Cement consumption in Indonesia has shown steady growth, reaching 65.2 million tons in 2021, an increase of 4.3% from the previous year. PT XYZ, a cement distributor, plays a vital role in ensuring the supply of cement in the regions of Bali, NTB, NTT, and East Kalimantan. However, the current distribution process is not optimal as deliveries are made solely based on customer demand, leading to stock shortages and high shipping costs. To address these issues, distribution will be planned and scheduled using the Distribution Requirements Planning (DRP) method. With effective scheduling and planning, customer demand will be met more efficiently, and sales performance will improve as demand is fulfilled promptly and in the right quantities. Consequently, distribution costs can be minimized. The results of the study indicate that the implementation of DRP has significantly improved distribution efficiency. Cement distribution has become organized and scheduled on a monthly basis, ensuring optimal product availability with more efficient shipping costs. Before the implementation of DRP, distribution costs totaled IDR 134,697,600,000, and this amount decreased to IDR 115,190,064,000 after the application of DRP, reflecting a cost savings of IDR 19,507,536,000, or 14%. Thus, the application of DRP has enabled the optimization of inventory management, enhanced operational efficiency, and significantly reduced distribution costs.

Abstract

Pengendalian persediaan sangat krusial untuk menjaga kelancaran operasional perusahaan, kepuasan pelanggan dan efisiensi biaya. Banyak perusahaan menghadapi tantangan dalam mengelola banyak item yang bersumber dari satu pemasok, khususnya ketika terbatasnya kapasitas penyimpanan. Hampir semua perusahaan mengelola lebih dari satu jenis item dari satu pemasok saja agar memperoleh efisiensi pesanan terpusat. Namun, hal ini menimbulkan tantangan dalam menentukan kuantitas pemesanan optimal dan menjaga tingkat layanan tanpa melebihi batas Gudang. Penelitian ini bertujuan untuk membandingkan sistem persediaan multiitem single supplier dengan kendala keterbatasan luas gudang, sehingga diperoleh kebijakan optimal karena metode tersebut dapat menurunkan total biaya persediaan lebih dari 30%. Penelitian ini menggunakan pendekatan komparatif dengan 4 skenario (EOQ; EOQ kendala luas Gudang; Model Inventory Multi Item; Model EOQ dengan Metode Multi Item Single Supplier dan luas kebutuhan yang dibutuhkan) dengan tujuan menganalisis dan membandingkan beberapa model pengelolaan persediaan dengan mempertimbangkan kendala-kendala nyata seperti luas gudang dan kebijakan pemesanan. Hasil penelitian menunjukkan bahwa setiap pendekatan memiliki keunggulan dan keterbatasannya masing-masing. Skenario 1 menunjukkan efisiensi biaya tertinggi namun tidak dapat diterapkan karena kebutuhan ruang yang melebihi kapasitas gudang. Skenario 2 berhasil menekan kebutuhan ruang hingga di bawah batas maksimum, tetapi menyebabkan lonjakan biaya yang signifikan. Skenario 3 menawarkan efisiensi biaya yang lebih baik dibanding skenario 2, namun masih belum feasible karena kebutuhan ruang yang besar. Sementara itu, Skenario 4 yang mengintegrasikan pendekatan multi-item single supplier dengan kendala ruang terbukti menjadi solusi paling seimbang, karena mampu memenuhi batasan fisik gudang sekaligus mempertahankan efisiensi logistik. Skenario 4 direkomendasikan sebagai model yang paling realistis dan aplikatif untuk diterapkan dalam pengelolaan persediaan di Gudang Material 2.

Abstract

Tourism journeys always begin with a planning stage, involving the selection of destinations to visit and the accommodation to be used throughout the trip. The Orienteering Problem with Hotel Selection (OPHS) serves as a model for recommending multi-day travel itineraries that are both efficient and profitable, as it aims to maximize total reward (or profit) while keeping the total travel distance within reasonable limits. This research extends the conventional OPHS by incorporating the time-dependent satisfaction of destinations, resulting in a model referred to as the Orienteering Problem with Hotel Selection and Time-Dependent Satisfaction (OPHS-TDS). The motivation for this development arises from the observation that the quality of tourist experience at certain destinations varies depending on the time of arrival. This phenomenon is particularly evident in nature-based attractions, where visiting during specific period can significantly affect both the visitor’s experience and the perceived benefit gained from the trip. The study presents a mathematical formulation of the OPHS-TDS and proposes a solution approach based on the Skewed Variable Neighborhood Search (SVNS) algorithm by allowing exploration of wide range neighborhood of solutions to search for near optimum solution. Computational experiments on benchmark datasets demonstrate that SVNS is efficiently solve OPHS-TDS with only 3.17% average differential with ILP, and further experiments using real-world data from the Province of Bali confirm the model’s applicability and potential in practical multi-day tourism planning scenarios.
