Abstract

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.

Abstract

Revolution of industry 4.0 initiated by the German government, starting from the development of individual innovation behavior especially in the fields of robotics, digital technology, and information, has caused distortions to the future skills requirements. Some of the skills needed a lot in the past are now starting to experience a shift towards less needed. Some are even unnecessary because they are replaced by automation and robots. The emergence of several new skills (skills 4.0) that are more dominant is needed to make every interested party to prepare themselves to face the challenges of the revolution of industry 4.0. Students are one of the interested parties who will face the challenges of the revolution of industry 4.0 after they graduates from the formal higher education. This study determines the readiness of students in facing the revolution of industry 4.0, influenced by the mastery of skills 4.0 and individual innovation behavior with their innovation behavior as a mediating variable. Respondents in this study are 233 undergraduate students of the Andalas University. Using a cluster sampling technique, the data is collected using Likert scale based- questionnaire after which calculations are then performed using the Smart-PLS Program software 3.2.8. The results show that skills 4.0 and individual innovation behavior have a positive effect on students' readiness in facing the challenges of the revolution of industry 4.0. It implies that the students need to improve their mastery of skills 4.0 in order to prepare themselves to face the challenges of the revolution of industry 4.0.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

Sistem transportasi yang baik dan memadai merupakan hal penting yang harus diperhatikan untuk memenuhi kebutuhan pelayanan terhadap keperluan masyarakat dalam menjalankan aktivitasnya setiap hari. Aktivitas transportasi tidak hanya berlangsung pada siang hari, namun juga dilakukan pada malam hari sehingga keberadaan lampu penerangan jalan sangat penting untuk menerangi jalan dan melancarkan kegiatan transportasi tersebut. Saat ini kondisi lampu jalan di Kota Padang banyak yang mengalami kerusakan. Penyebab utama kerusakan lampu jalan adalah tegangan, yaitu beban puncak yang terjadi mulai dari pukul 18.00-23.00 WIB. Berdasarkan hal tersebut, penelitian ini menggunakan Key Performance Indicator (KPI) untuk menghasilkan standar penilaian kinerja dalam melakukan penilaian terhadap pemeliharaan lampu jalan yang ada di kota Padang. Perancangan dimulai dengan mengidentifikasi KPI yang didapatkan dari studi literatur. KPI yang telah didapatkan divalidasi kepada stakeholder untuk mendapatkan KPI yang cocok untuk diterapkan di kota Padang. Setelah itu dilakukan pembobotan KPI melalui perbamdingan berpasangan dengan menggunakan metode AHP.
