PENGUKURAN NILAI INTANGIBLE PADA PROJECT BASED ORGANIZATION

Intangible factor is a very important factor. The importance of measuring the value of intangible has become a challenge for a company nowadays, not only for functional companies (functional-based organization) but also for project companies (project-based organization). This research aimed to identify intangible factors and measure the value of intangible in organizations which are in the form of project. The value of measured intangible can be used to predict the potential gained value of a project conducted by a company. The object of this research is a project-based company running business on repair and maintenance service (after sale service), logistic, and general contractor (general construction). The identification process of intangible was done by using Analytic Hierarchy Process (AHP) method.  Then, a prediction model for determining the project value was made by considering its intangible factor. This model was made using multiple-regression analysis. Intangible factors that have been identified are technology, human knowledge, management capability, networking, and financial support. The intangible values of each intangible factor and their qualities respectively are: management capability is 0.444, networking is 0.262, financial support is 0.152, human knowledge is 0.089, and technology is 0.052. From the measured intangible, it can be seen that the value of mean square error (MSE) is 0.0065. It shows that this prediction model can be used to predict a project value by considering its intangible facto

A MATHEMATICAL MODEL FOR DELIVERY ZONE GROUPS BASED ON COURIER ASSIGNMENT OPTIMIZATION: A CASE STUDY IN A LOGISTICS SERVICE PROVIDER

Logistics service providers are the key stakeholder in Indonesian logistics activities that are growing significantly and face many challenges. In this research, a case study on a logistics service provider located in the city of Yogyakarta Indonesia is evaluated. The provider is currently experiencing rapid growth indicated by increasing delivery volume and scopes. However, optimal resource management has not been able to be adequately calculated, such as inefficient courier assignment and overloaded couriers' volume. Thus, this study aims to minimize total distances through optimal zone groups under several restrictions. An optimization approach is selected in this research by initially building a mathematical model using a standard form of linear programming. Then, the mathematical model is solved to generate minimum distances. The result indicated that the total minimum distances had been reached with considerable changes in delivery zone grouping, and the couriers' capacity was optimally utilized without overloaded capacity. These zone groups can be used as a reference for further research by taking into account some restrictions such as packages fluctuations as well as adding objective to minimize couriers' traveling time

Evaluation of Workers’ Working Postures based on RULA and MCDM: An Application to a SME Producing Kitchenware in Indonesia

Currently, it is obvious that occupational health and safety culture in companies is on the rise including a focus on workers’ working postures. However, the implementation of these initiatives tends to be notably deficient, particularly in small and medium-sized enterprises (SMEs). This research aims to introduce a framework for evaluating workers’ working postures taking into account ergonomic factors and other influential factors. In this study, the developed evaluation model was applied to an SME producing kitchenware situated in Indonesia using rapid upper limb assessment (RULA), and the method was combined with multi criteria decision-making (MCDM). There were five criteria identified, namely RULA score (C1), the activity’s level of importance (C2), duration (C3), work station environmental condition (C4), and supportive equipment (C5). These five criteria were considered to evaluate five working postures on the production floor. The result indicated that based on the RULA score, five postures were categorized as high risk. Besides, by considering the criteria, working posture in assembly activity (posture 3) has the highest risk level which requires immediate corrective action. This research is applicable as the evaluation of work posture is assessed by considering ergonomic factors and the level of importance for each activity.&nbsp

Optimizing inventory policy to mitigate stockouts during the COVID-19 pandemic: a case study of a pharmacy in Riau, Indonesia

This paper studies on proposed inventory policy at a well-known pharmacy in Riau Province, Indonesia. Pharmacy X often experiences stockouts, especially during the critical period of the COVID-19 pandemic. These stockouts lead to lost sales. The Q and P inventory models are used to determine the optimal order quantity and order period using several simulation scenarios. Storage capacity and the ability of suppliers to supply drugs are constraints in this study. However, only 7 SKUs that often run out will be examined. The purpose of this paper is to minimize the shortage level of the SKUs using a parameter of shortage costs. After simulation, it was proven there was a decrease in the shortage costs in each SKU compared to the actual state. The reduction reached 23% - 74%

Analisis Lean Manufacturing Pendekatan VSM dan FMEA untuk Meminimasi Pemborosan pada Salah Satu Perusahaan Logam di Jawa Tengah

Latar Belakang: PT. Aneka Adhilogam Karya adalah sebuah perusahaan swasta nasional yang bergerak dalam bidang pengecoran logam dan memproduksi berbagai macam perlengkapan sambungan pipa air minum atau yang dikenal dengan Pipe Fittings. Seiring dengan perkembangan zaman, permintaan produk logam yang tinggi perusahaan dihadapkan dengan berbagai permasalahan salah satunya adalah pemborosan pada proses produksi. Metode: Untuk mengurangi pemborosan tersebut, salah satu cara yang dapat dilakukan adalah dengan menerapkan Value Stream Mapping (VSM) untuk mengidentifikasi aktivitas yang tidak perlu, mengevaluasi dan memperbaiki proses produksi yang tidak efisien, serta meminimalkan waktu tunggu dan persediaan yang berlebih dan metode Failure Mode and Effect Analysis (FMEA) untuk mengidentifikasi dan mengatasi risiko atau kegagalan pada proses produksi. Kesimpulan: Berdasarkan VSM yang telah dibuat dapat diketahui waktu total untuk proses produksi adalah sebesar 294.388 s. Berdasarkan hasil pengolahan dari FMEA jenis pemborosan yang memiliki nilai RPN tertinggi adalah Transportation sebesar 215. Usulan perbaikan berdasarkan jenis pemborosan yang terjadi yaitu, Pengecekan mesin secara rutin, automatisasi proses pengambilan, evaluasi tata letak lantai produksi dan identifikasi, penerapan budaya 5R (Ringkas, Rapi, Resik, Rajin, dan Rawat)

Fuzzy AHP – DEMATEL Methods To Investigate Passengers’ Decision Factors On Using Public City Bus In An Indonesian Region

An advanced public transportation system becomes an indicator for a country. Accordingly, it is essential that the decision-makers (DMs) conduct an initial study based on passengers’ view in order to improve the public transportation services. Since involving multi factors, the problem is often solved using the multi-criteria decision-making (MCDM) approaches. This study aims to examine significant factors on passengers decision making to use public transportation using Fuzzy AHP and DEMATEL. The Fuzzy AHP method is proposed to determine criteria weights so that significant critera are obtained, then the causal relations including the criteria are visualized using DEMATEL. This study demonstrates the integration of the two MCDM methods in a BRT system in the region of Yogyakarta, Indonesia, and invites passengers and the DMs. The result indicated that 21 criteria are identified, while the 11 significant criteria are selected based on the Fuzzy AHP weight – α-cut screening. Besides, the DEMATEL has succeeded in describing the influence relationship for the criteria, where firstly, the significant criteria are classified into cause and effect group and secondly, the two criteria, namely coverage to strategic points and on time arrival, should be put on the top priority list. This study enables the DMs to solve public transportation problems more effectively. However, the follow-up study should be carried out by including other factors such as economic and sustainability to strengthen the decision-making process
