Abstract

In recent decades, self-efficacy has been one of the major subjects of interest in the field of psychology, with numerous studies published on the topic. This study aims to examine the psychometric features of the General Self-Efficacy Scale-12 (GSES-12), a widely used instrument for assessing general self-efficacy. The Indonesian adaptation of the GSES-12 was validated using item factor analysis (IFA). The study involved a total of 584 high school student participants (M-age = 16.02, SD-age = 1.39; boys = 266, girls = 318). The results obtained from the IFA indicate that the psychometric properties of the GSES-12 were satisfactory. The results exhibited a strong fit with the second-order IFA models and all items had statistically significant factor loadings. In addition, the results obtained from the multigroup IFA indicate that the configural invariance testing models exhibited a satisfactory level of goodness-of-fit (RMSEA < 0.06, CFI & TLI > 0.90). These findings suggest that there were no differences between the genders in the factor structure of the GSES-12.

Abstract

The initial ease of internet use has led to new challenges, one of which is the phenomenon of cyberloafing. Cyberloafing refers to the activity of accessing the internet during learning processes. The aim of this study is to modify the cyberloafing scale within an educational setting in Indonesia using the dimensions of sharing, shopping, real-time updating, accessing online content, and gaming/gambling. The modifications include contextualizing the original and adding new relevant items. Data collection was conducted using purposive sampling, involving 235 university students from various higher education institutions in Indonesia. The method used to test the validity of the cyberloafing model was confirmatory factor analysis. The results showed that out of 65 items, 20 were found to be valid, with a satisfactory total Cronbach’s alpha of 0.73-0.93 and McDonald’s omega of 0.71-0.93 for measuring reliability for each dimension of cyberloafing. The practical implication of this measurement tool is that it can be used to assess the intensity of cyberloafing among higher education students in Indonesia

Abstract

Abstrak: Analisis Penyebab Ketidakcocokan Stock Opname Komponen Sparepart Di Gudang Sparepart. Gudang adalah tempat untuk menyimpan material yang memiliki peranan penting dalam menjaga persediaan untuk proses produksi. Setiap akhir bulan, bagian gudang selalu melakukan pencocokan jumlah saldo akhir komponen pada bulan sebelumnya antara kartu stock dengan sistem inventory. Salah satu permasalahan yang sering terjadi di gudang sparepart adalah adanya ketidakcocokan jumlah saldo akhir komponen sparepart antara kartu stock dengan sistem inventory yang terjadi terus menerus. Permasalahan ini dapat membuat kesalahan dalam laporan stock opname yang mengakibatkan kerugian bagi perusahaan. Penelitian ini menggunakan pendekatan DMAIC (Define, Measure, Analyze, Improve, Control) untuk meminimalkan kesalahan saat pelaksanaan stock opname komponen sparepart. Berdasarkan hasil pengolahan data diperoleh penyebab ketidakcocokan stock opname antara stock real dengan sistem inventory adalah parts yang keluar gudang belum diinput di sistem, parts yang masuk gudang belum diinput di sistem, dan stock real belum dihitung. Penyebab parts yang keluar gudang belum diinput di sistem menjadi prioritas yang harus diselesaikan terlebih dahulu. Abstract: Analysis of Causes Incompatibility of Sparepart Components Stock Opname in Sparepart Warehouse. Warehouse is a place storage materials that have an important role in maintaining inventory for production process. The warehouse department always matches number of the final balance of the component in the previous month between the stock card and the inventory system. One of the problem that often occurs in spareparts warehouse is the mismatch number of the final balance of spareparts between the stock card and the inventory system that occurs continuously. This problem can cause errors in stock opname reports that result on losses for the company. This research uses a DMAIC (Define, Measure, Analyze, Improve, Control) approach to minimize errors during the implementation of spareparts component stock opname. Based on the results of data processing indicate that the causes of the stock opname incompatibility between the real stock and the inventory system are parts that come out warehouse have not been input in system, parts that come in warehouse have not been input in system, and real stock has not been calculated. The cause of the parts that come out warehouse have not been input in system is a priority must be resolved first.

Abstract

The turning process involves the linear removal of material from the work-piece and requires a relatively high amount of energy. The high energy consumption of the machining process increases carbon emissions, which affects the environment. Moreover, production costs will rise as the cost of energy rises. Energy savings during the machining process are crucial for achieving sustainable manufacturing. In order to determine and optimize the cutting parameters, this study creates a multi-pass turning processes optimi¬zation model. It considers cutting speeds, feed rates, and depth of cut. In this study, the model uses multi-objective optimization by incorporating three objective functions: processing time, energy consumption and product¬ion costs. OptQuest completed the proposed model in Oracle Crystal Ball software, then normalized and weighted the sum. Ordering preferences, the Multi-Objective Optimization based on Ratio Analysis (MOORA) approach is utilized. It ranks items based on their higher priority values. This paper provides a numerical example to demonstrate the application of an optimi¬zation model. Based on the preference order ranking results, the optimal values for three objective functions are as follows: total processing time of 4.953 min, the total energy consumption of 5.434 MJ, and total production cost of 395.21$.

Abstract

The COVID-19 pandemic has pushed people to experience the situasion of volatility, uncertainty, complexity, and ambiguity (VUCA) which has the potential to cause various mental health problems. Research on Intolerance of Uncertainty (IU) is immportant because of its crucial role as a risk factor for mental health disorders. Unfortunately, the measuring tool for that cognitive function has not yet been adapted into Indonesian culture and language. This Study aims to adapt the 12-item Intolerance of Uncertainty Scale (IUS-12) to Indonesia and determine the psychometric properties of the scale.
