Abstract

Several companies indirectly give excessive workloads that are considered to increase productivity. Besides workload, the work environment is important in encouraging employees to work optimally. Ruang Klambi Convection does not have a good work system due to the absence of an effective work schedule and poor work environment conditions. This can allow for overload or excessive workload on each worker. The primary motivation for this study is to improve work efficiency at Ruang Klambi Convection, which faces problems of excessive workload and a non-optimal work environment. Through the Work Sampling and Work Load Analysis approach, this study aims to measure standard production time and determine the optimal number of workers, thus reflecting a significant paradigm in measuring standard time. This study was conducted by calculating the standard time required to produce a midi dress with an average order of 30 pieces, measuring and analyzing the workload level from each workstation, and determining the optimal number of workers. Based on the calculations, the results show that the standard time to fulfill an order of 30 pieces is 106.2 hours (equivalent to 5 days). In addition, based on the analysis of the workload of each workstation, two workstations are classified as overloaded, namely workstations I (Pattern Making and Cutting) and II (Sewing), so it is necessary to add a worker to both workstations to achieve a fit workload.

Abstract

The rapid growth of the technology industry poses significant challenges for transportation providers in maintaining service quality, particularly in addressing the gap between customer expectations and perceptions and ensuring efficient resource management. This study explores factors influencing service quality in Malaysian transportation provider companies using the SERVQUAL method, quality function deployment (QFD), and linear programming optimization. Key objectives include identifying issues in the TPM application service process, measuring gaps between customer perceptions and expectations, identifying critical service attributes using importance-performance analysis, and prioritizing technical responses to improve service quality using linear programming optimization. Based on root cause analysis, importance-performance mapping, and the house of quality framework, the study identified four key recommendations: updating standard operating procedures (SOPs) and monitoring service issues, providing driver training on methods and skills, implementing stricter driver selection criteria with a focus on code of conduct compliance, and developing an improved application interface for better customer location accuracy. These measures aim to enhance the efficiency and effectiveness of services, ensuring better alignment with customer needs and expectations while addressing critical operational challenges. By bridging the service quality gap, this research provides actionable insights to support continuous improvement in the Transportation Provider Company from Malaysia.

Abstract

XC Clenaindo Company is a manufacturing company that provides cleaning and sanitation services in Indonesia. However, defects that exceeded the company's tolerance limits were found in hand sterilizer products. This research aims to improve product quality so that it satisfies customer needs. Analysis was conducted to determine the leading causes of product defects using the Six Sigma Define, Measure, Explore, Design, and Implement (DMEDI) method. The DMEDI Six Sigma method is a quality improvement method with a creative approach so that the resulting solution can be a new work system design. The results of the defined process research found two problems, namely product defects because the Sterobac hand sterilizer bottle was convex and the length of the label installation process. At the measure stage, it was discovered that the problem was in the filling and labeling process, which was influenced by the increasing number of requests. At the exploration stage using the 5 why deep interview method, it was discovered that the problem was due to the lack of temperature during the liquid pouring process and the label design making the sticking process difficult. So, the work process was redesigned at the filling stage, and a new label design was created, which made it easier for workers to stick labels and apply the 5S concept. The final stage was implemented by designing the Poka-Yoke Form and Worker Operational Standards for the Filling. This research results in a reduction in the number of defective products.

Abstract

Intisari: Kupa Ngupi adalah salah satu kedai kopi yang berada di Bekasi. Pada saat ini, kondisi penjualan Kupa Ngupi sedang mengalami penurunan. Salah satu usaha yang perlu dilakukan adalah perubahan strategi yang mendasar. Pendekatan yang digunakan untuk mengevaluasi strategi dan merumuskan strategi baru adalah dengan Blue Ocean Strategy. Langkah pertama dipetakan posisi perusahaan di pasar melalui pembuatan matriks IFAS dan EFAS. Melalui matriks ini dapat diketahui kondisi internal dan eksternal perusahaan. Faktor internal adalah seluruh faktor yang dapat dikendalikan sedangkan faktor eksternal merupakan pengaruh yang datang dari luar dan tidak bisa dikendalikan secara langsung. Strength dan weakness merupakan faktor internal perusahaan, opportunity dan threat merupakan faktor eksternal perusahaan. Berdasarkan matriks IFAS dan EFAS, total skor kekuatan adalah 1,08 dan kelamahan 1,32, selisihnya -0,24 (dipetakan pada sumbu x). Sedangkan total skor peluang 1,833 dan skor ancaman 0,875, selisihnya adalah 0,958 (dipetakan pada sumbu y). Dari hasilperhitunga inu terlihat bahwa perusahaan berada pada Kuadran III. Pada kuadran ini, perusahaan menghadapi peluang besar, namun ada kendala kelemahan internal sehingga perlu dilakukan perubahan strategi untuk keluar dari ruang pasar yang sudah ada. Melalui Kanvas Strategi awal terpetakan bahwa Kupa Ngupi terlihat masih berada di bawah pesaing. Untuk itu perlu dilakukan perubahan dengan mempergunakan Kerangka Kerja Empat Langkah sehingga dpat digambarkan kanvas strategi kearah penciptaan Kupa Ngupi yang unggul. Setelah dilakukan analisis ditemukan bahwa faktor yang harus dihapuskan berkaitan dengan pola penataan ruangan yang tidak berkonsep. Faktor yang perlu dikurangi adalah tingkat ketidak teraturan penataan peralatan dan perlengkapan pembuat kopi. Hal yang perlu ditingkatkan adalah varian dan inovasi produk dan menambah menu ‘bundling package’. Terkahir hal yang perlu dicitptakan adalah berkaitan dengan penciptaan situasi kenyamanan yang direpresentasikan dalam bentuk interior minimalis namun modern. Hal ini sesuai dengan nilai yang dihasilkan yaitu 3,65, kopi ready to go bernilai 3,64, dan speciality kopi bernilai 3,75. Nilai rata-rata usulan faktor diciptakan tersebut di atas 2,9 yang berarti faktor tersebut penting untuk diciptakan. Kanvas strategi akhir menunjukkan adanya kenaikan faktor internal perusahaan dibanding pesaing, ditambah dengan adanya faktor baru yang diciptakan. Usulan lain yang diberikan adalah motto baru “Kopi nikmat, harga gak bikin penat”. Abstract: Kupa Ngupi is one of Bekasi's coffee cafes. At the meantime, Kupa Ngupi sales conditions are decreasing. A fundamental shift in strategy is one effort that must be made. The Blue Ocean Strategy is a method for evaluating existing strategies and developing new ones. The first step is creating IFAS and EFAS matrices to map the company's market position. The internal and external characteristics of the firm may be examined using this matrix. Internal factors are those that can be managed, whereas external factors are those that originate from outside and cannot be directly controlled. The company's internal factors are its strengths and weaknesses, while its external elements are its opportunities and threats. According to the IFAS and EFAS matrices, the total strength score is 1.08 and the weakness score is 1.32, with a -0.24 difference (mapped on the x-axis). While the overall opportunity score is 1.833 and the threat score is 0.875, the difference is 0.958. (mapped on the y-axis).The results of this analysis show that the firm is in Quadrant III. The firm confronts enormous potential in this quadrant, but there are internal weaknesses restrictions, therefore the strategy must be changed to exit the present market area. The first Strategy Canvas revealed that Kupa Ngupi was still lagging behind competitors. As a result, modifications must be made utilizing the Four-Step Framework so that a strategy canvas may be created toward the development of improved Kupa Ngupi. Following the research, it was discovered that the elements that had to be deleted were connected to a pattern of room layout for which there was no conceptualization. The amount of inconsistency in the placement of coffee manufacturing equipment and supplies should be minimized. Product variations and innovations, as well as the addition of a 'bundling package' menu, need to be enhanced. The final element that has to be developed is a relaxed atmosphere, which is represented by a minimalist yet modern interior design. This is aligned with the resultant value of 3.65, ready-to-drink coffee is worth 3.64, and speciality coffee is worth 3.75. The average value of the proposed factor generated is more than 2.9, indicating that the factor is relevant enough to be established. The final strategy canvas indicates an increase in the company's internal factors as compared to competitors, as well as the creation of new features. Another suggestion was for a new motto “Kopi nikmat, harga gak bikin penat".

The main raw materials for the production of secondary aluminum ingots are base metal, scrap obtained from junk collectors and addictive materials such as silicon and copper. Currently the company is less than optimal in implementing production planning which causes the utilization of production facilities not to be maximized and the use of gas fuel energy which causes high production costs. The purpose of this research is to obtain the results of demand forecasting and production planning that can reduce production costs. In this research, the demand forecasting model is designed using the Artificial Neural Network method to obtain demand projections for the next 3 periods. Furthermore, production planning is carried out using a Linear Programming approach which has taken into account the availability of production resources so as to increase the utilization of production facilities with minimum production costs. Based on the production plan, it is possible to calculate the inventory requirements for raw materials forming the product. Forecasting results using the Artificial Neural Network method provide demand forecasting results with a small error value. The results of requests for period 1 were 804,645 kg, period 2 were 529,307 kg, and period 3 were 788,669 kg. Next, by using the output of demand forecasting using ANN, a production plan is carried out that provides the optimal production quantity solution, namely for AC2C, ADC12 and HD2 products that produce minimum production costs. Based on the calculation results of production planning, it can be determined the need for base metal, scrap and addictive raw materials to support production operations in aluminum companies.

Abstract

Intisari— Biaya distribusi produk yang masih cukup tinggi dan juga lokasi konsumen yang tersebar di berbagai wilayah Pulau Jawa menjadi sebuah tantangan yang cukup kompleks bagi UKM Mina Indo Sejahtera, agar dapat selalu memenuhi mayoritas bahkan seluruh demand dari konsumen potensialnya dengan biaya yang seefisien mungkin. Oleh karena itu, diperlukan sebuah desain jaringan supply chain yang optimal bagi UKM Mina Indo Sejahtera, agar seluruh konsumen dapat tetap terlayani dengan total biaya distribusi yang tetap efisien. Metode yang digunakan yaitu dengan menggunakan formulasi model matematis haversin dan juga Center of Gravity (COG) Adjusting. Koordinat lokasi yang dihasilkan terbukti mampu meminimalkan total jarak tempuh dan juga total biaya yang harus dikeluarkan UKM Mina Indo Sejahtera untuk mendistribusikan produknya ke seluruh market khususnya di Pulau Jawa. Hasil penurunan total jarak tempuh dan total biaya distribusi bulanan yang didapatkan melalui formula haversin dan metode COG Adjusting yaitu sebesar 22% dan 24%. Sehingga, apabila UKM Mina Indo Sejahtera memusatkan distribusinya pada lokasi baru tersebut, total jarak yang ditempuh ke seluruh pasar di Pulau Jawa dapat diminimalkan menjadi sejauh 1.720, 4 kilometer, dengan total biaya distribusi bulanan yang dikeluarkan hanya sebesar Rp Rp 11.736.455,-.. Abstract— The cost of product distribution is still quite high and also the location of consumers spread across various regions of Java Island is a fairly complex challenge for Mina Indo Sejahtera SMEs, in order to always meet the majority and even all demands from potential consumers at the most efficient cost possible. Therefore, an optimal supply chain network design is needed for Mina Indo Sejahtera SMEs, so that all consumers can still be served with efficient total distribution costs. The method used is by using a haversin mathematical model formulation and also Center of Gravity (COG) Adjusting. The resulting location coordinates are proven to be able to minimize the total distance traveled and also the total costs that must be incurred by Mina Indo Sejahtera SMEs to distribute their products to all markets, especially in Java. The results of the reduction in total mileage and total monthly distribution costs obtained through the haversin formula and the COG Adjusting method are 22% and 24%, respectively. Thus, if Mina Indo Sejahtera SMEs concentrated their distribution in the new location, the total distance traveled to all markets on Java Island could be minimized to 1,720, 4 kilometers, with a total monthly distribution cost of only Rp. 11,736,455,-.

Abstract

Intisari— Emisi karbon terbesar berasal dari residu yang ditinggalkan dari aktivitas manusia. Pada volume besar dan tak terkendali, emisi ini menjadi penyebab utama pemanasan global. Sumbangsih emisi gas buang juga bersumber dari aktivitas sehari-hari masyarakat. Di negara Indonesia, yang termasuk dalam kategori negara berkembang, aktivitas masyarakat lebih banyak terakumulasi di tingkat desa. Desa Penambangan merupakan desa yang terletak di kabupaten Sidoarjo provinsi Jawa timur yang memiliki luas wilayah kurang lebih 150 Ha dengan jumlah penduduk 5.816 jiwa. Pada penelitian ini dilakukan kajian dengan pendekatan system dynamics bagaimana penanganan sampah di desa tersebut. Model system dynamics yang dihasilkan bisa digunakan untuk bahan pertimbangan pemerintah desa Penambangan dalam menangani sampah. Berdasarkan simulasi model, seiring berjalannya waktu, total tingkat emisi karbon dari sampah desa meningkat rata-rata 10.8% tiap bulan. Dengan melakukan penanganan sampah organing yang lebih komprehensif, emisi karbon berkurang hingga 90.4% dibandingkan kondisi awal di level model. Abstract— The largest carbon emissions come from residues of human activities. In large and uncontrolled volumes, these cause global warming. As an accumulation, The emissions also come from the daily activities of the community. In developing countries such as Indonesia, community activities are mostly accumulated at the village level. “Penambangan” is one of villages located in Sidoarjo, East Java, which has an area of approximately 150 hectares with a population of 5,816 people. In this study, a system dynamics approach was carried out on how to handle waste in the village. The resulting model can be used by local government for consideration in handling them. Based on the model simulation, the total level of carbon emissions of the community increased by an average of 10.8% per month. By carrying out more comprehensive handling of waste, carbon emissions are reduced by 90.4% compared to the initial conditions at the model level.
