The definition and function of inventory management reveal the importance of modern industry in formulating policies that regulate the supply of raw materials, semi-finished products, and finished products. Unfortunately, most companies fail to consider the characteristics of their raw materials when determining inventory strategies. Raw materials that are perishable are those that consider their service life and storage time. Inventory management plays a crucial role in supply chain management, especially for perishable raw materials, such as food products. PT X, a food business in Padang, experienced difficulty in meeting the demand for rendang products due to a lack of raw materials. Therefore, this study aims to develop an inventory management model that takes into account the perishable raw materials' expiration time. The model development consists of three stages: model development design, inventory model formulation, and model testing. The proposed model resulted in a storage time interval of five days and an optimal order quantity of 34 kg of meat with a safety stock of 14 kg. Implementing this model led to lower total inventory costs for PT X than the actual conditions of the company. The total inventory cost obtained using this model is Rp279,797,822. This study emphasizes the importance of considering the characteristics of raw materials in determining inventory strategies to optimize inventory management effectively and efficiently. The study's findings can serve as a reference for other food businesses encountering similar inventory management challenges in the perishable food industry.

This research aims to evaluate the egg-laying chicken feeder that was designed at egg-laying chicken farm small and medium enterprise (SME). The main reason of this tool design was due to the worker’s complain of feeling pain during the feeding process. Evaluation was performed based on Nordic Body Map questionnaire result, physiological workload, and NIOSH lifting equation calculation. The observed work ranged from the feed filling in the basket until all feeds were distributed. The results showed that the %CVL was in the range of 18%-30% and the energy consumption of workers was in the range of 1.24-3.00 Kcal/minute. Thus, physiologically, the work activities carried out by the feed workers were categorized as very light workload. Meanwhile, evaluation using Lifting Index (LI) methods in the process of feeding showed the LI value ranged from 0.9-1, therefore this activity is safe to perform manually. Based on the prototype evaluation on the feeding aid, the process of feeding activities was more effective 1.5 times faster than the old tools. In addition, with the use of this new tool, the feeding process was easier to adjust the dose each time.

The geographical condition of Sungai Pisang Village located on the coastal fringe and not too far from the famous island tourism which potential in West Sumatera becomes an opportunity for the people of Sungai Pisang, especially the fishermen to increase their standard of living. But in reality, the outsiders in the Bungus area are more likely to take advantage of the opportunity because of their location close to the city center. The tourists can only be seen from afar by biduk fishermen of Sungai Pisang. Most tourists prefer to use Tour and Travel services from Bungus area. Biduk fishermen are only bringing few tourists to the island tour even though the price offered is much cheaper. Based on preliminary study, there are problems such as the lack of knowledge of the fisherman on the effective product marketing strategy. So far, there are no marketing tools to promote the transportation services of biduk fisherman to the island tourism in the Sungai Pisang broadly. Therefore, it is necessary to design a marketing information system for island tourism biduk. The marketing information system is a mobile web-based designed using PHP programming language and supported by the MySQL database. The information marketing system is expected to increase the number of tourists who use the island tourism biduk as an effort to increase the sustainable fishermen's economy.The geographical condition of Sungai Pisang Village located on the coastal fringe and not too far from the famous island tourism which potential in West Sumatera becomes an opportunity for the people of Sungai Pisang, especially the fishermen to increase their standard of living.

Construction project implementation process is often found inefficiency and problems at every stage of the construction process. Inefficiencies are caused because construction projects have high levels of fragmentation. The high level of fragmentation cannot be separated from the complexity and many work items on construction projects. To reduce the problem of inefficiencies in the implementation of construction projects required good supply chain management or better known as supply chain management (SCM) on construction projects. Therefore it is necessary to study the management of SCM in the construction project to reduce the inefficiency that occurred. SCM management of construction projects is done by designing SCM performance measurement systems in construction projects. This performance measurement system produces indicators that are combined with the Supply Chain Operation Reference (SCOR) method. So it helps in performing SCM performance measurement on construction projects. From the design results, obtained 14 SCM performance indicators on construction projects. The performance indicators are then used to perform SCM performance measurement of cement plant construction projects. From the measurement results obtained SCM performance value of 41 from a scale of 100. This shows the performance of SCM on construction projects for the construction of the cement plant is at a marginal level.

This research aims to design optimal portfolio with a case study of stocks listed on the Indonesia Stock Exchange (IDX) that conduct transactions in the period 2011-2015. The sample used were 396 companies listed on nine sectors in BEI. Arbitrage Pricing Theory (APT) method is used to determine the realized return, expected return, and efficient portfolio involving four macroeconomic factors (Stock Price Index (IHSG), interest rate of Indonesian Bank Certificates (SBI), Inflation and Exchange Rate of Rupiah against the US Dollar). Efficient portfolio is formed by 231 undervalued companies. While the optimal portfolio with the Excess Return to Beta (ERB) approach was formed by 42 companies with a ERB value greater than (or equal to) cut-off point (0,1912). Under the uncertainty of the investment climate due to the global financial crisis, the decision to make investments needs to be done carefully and consider various factors, including macroeconomic factors. This research has succeeded in designing an optimal portfolio that can be a guide for investors to determine investment decisions.

The application of digital technology increases productivity, expands market reach, helps small and medium industries (SMIs) adapt to various changes, and provides a great contribution to sustainability. Sustainability emphasizes the importance of maintaining economic, environmental, and social balance in the long term, while resilience describes the ability of SMIs to confront and recover from various disruptions. However, the SMIs in Padang are less aware of the importance of implementing digitalization sustainably to achieve SMI resilience. Several indicators remain unmet by SMIs. This study aims to compile and validate digitalization and sustainability indicators appropriate to the context of local SMIs. These indicators were collected from various literature sources that include digital literacy, digital marketing, economic, environmental, and social sustainability, and resilience aspects. The validation process involved five experts from academia, government, and industry practitioners selected based on their expertise in the fields of the aforementioned aspects. Experts assessed the relevance and clarity of each indicator using the Likert scale, then the results were analyzed with the Aiken index and tested for reliability between assessors using SPSS to ensure consistency of assessments. The results of the study show that these indicators are aligned with the dimensions measured, particularly those that affirm the importance of digital literacy, digital marketing, and social aspects of sustainability in strengthening the resilience of SMIs. These validated indicators were then used to develop a conceptual model that can be a strategic reference for stakeholders and policymakers to increase the competitiveness, resilience, and sustainability of SMIs in Padang.

Each company will seek to improve performance in order to obtain the optimal results and customer satisfaction. One of the factors that affect the performance of the company is the supplier or vendor, which acts as a supplier of the operational needs of the company consisting of raw materials and spare parts manufacturing equipment. The existence of suppliers is crucial for the production process and the product to be produced. Therefore, it is necessary to a proper selection of suppliers so as to eliminate all risks that would result in losses for the company. PT. Semen Padang is one of the companies involved in the cement industry is one of the members of PT. Cement Indonesia as the Holding Company. Until now both PT. Semen Padang and PT. Cement Indonesia does not have yet a standard method in the selection of suppliers for the procurement process of goods and services. This study aims to design the proposed indicator in the evaluation of suppliers to determine the bidder's list on a tender for the procurement of services in PT. Semen Padang. Based on the literature study, it obtained six criteria i.e: quality, delivery, performance history, price, technical capability, and procedural compliance, which are divided into 13 indicators of performance evaluation. These indicators will be validated by the cement industry. Future studies will design a model of evaluation of suppliers using Analytic Hierarchy Process (AHP) method to determine the bidder's list on a tender for the procurement of services in PT. Semen Padang.

Data dari Dinas Koperasi dan UMKM Kota Padang menunjukkan peningkatan jumlah UMKM yang signifikan. Namun, pertumbuhan ini belum diiringi dengan kemampuan pengelolaan produksi yang memadai, yang masih menjadi kelemahan utama UMKM. Untuk mengatasi permasalahan tersebut, konsep lean manufacturing (LM) dapat menjadi solusi strategis yang relevan. Penelitian ini bertujuan untuk melakukan kajian empiris melalui pengimplementasian LM pada UMKM di Kota Padang dengan studi kasus pada UMKM Kripik Balado Salsabila. Studi pendahuluan menunjukkan terdapat pemborosan pada proses produksi. Hasil pengumpulan data kemudian diolah dengan merancang VSM dan PAM, karena dapat mengidentifikasi pemborosan pada proses produksi dengan gambaran visual dan analisis nilai pada kegiatan. Terdapat 7 proses yang masih berkategori tidak bernilai tambah dengan persentase bernilai tambah yaitu 81,96%. Selanjutnya, dilakukan identifikasi pemborosan berdasarkan konsep 9 wastes of lean beserta penyebab pemborosan menggunakan metode fishbone diagram, yang efektif untuk menentukan akar permasalahan. Analisis ini menjadi dasar perancangan usulan perbaikan, yang mengacu pada pendekatan 5S dan lean-green manufacturing. Beberapa usulan perbaikan yaitu pengadaan alat operasional yang lebih efisien, perancangan ulang layout pabrik, dan penyusunan skema pengelolaan limbah. Future state VSM dan PAM menunjukkan adanya peningkatan persentase bernilai tambah sebesar 7,88%. Terakhir, dilakukan pembahasan mengenai implikasi penelitian, yang mendeskripsikan manfaat penerapan LM, faktor pendukung, dan faktor penghalang penerapan LM pada UMKM di Kota Padang.
