TECHNOLOGY LEADERSHIP IN INDONESIAN JUNIOR HIGH SCHOOLS DURING THE POST-COVID ERA: A CASE STUDY OF SPIRITUAL DIMENSIONS
No full textCOVID-19 in Indonesia necessitated a shift from traditional face-to-face learning to technology-based distance learning. This transition also redefined the role of school principal who must lead change and work in new ways. This study aims to explore the new role of the principal as a technology leader and develop a technology leadership model in learning in the new normal era. Employing a qualitative approach with a single case study method, the study involved 20 participants, including 5 principals, 5 vice principals, 5 IT coordinators, and 5 subject teachers from five public junior high schools (SMP Negeri) in Surabaya, Indonesia.. The findings study show that school principal has a key role in keeping the school functioning well in the new normal era. This findings highlight the latest model of technology leadership in education by developing 5 dimensions of technology leadership from NETS-EL 2018 into 6 dimensions. The spiritual dimension makes technology leaders and teachers are more effective in leading schools during and after COVID-19. These findings specifically contribute to the development of a technology leadership framework and generally complement existing leadership theories
Utilization of Steel Aggregate and Iron Sand as Heavyweight Concrete for Gamma Radiation Shielding
No full textThis study aims to produce a homogenous and workable conventional heavyweight concrete (HWC) with similar performance as pre-placed HWC in attenuating radiation by increasing the concrete density with no risk of segregation. HWC was mixed using steel aggregate and iron sand with a specific gravity of 7.78 and 4.14, respectively. A w/c ratio of 0.5 was applied to obtain proper workability and viscosity modifying agent (VMA) was used to prevent segregation. The radiation tests were carried out using 133Ba (356 keV), 137Cs (662 keV), and 60Co (1170 keV & 1330 keV) gamma sources. The results obtained a concrete density of 5133.07 kg/m3 with no sign of segregation and a compressive strength of 18.61 MPa. Based on the radiation test, the conventional HWC was effective in reducing the shielding thickness by 50.41%. Our findings provide a workable conventional HWC with high gamma attenuation to replace an enormous dimension of normal concrete
Least-squares Smoothed Shape Functions for Constructing Field-Consistent Timoshenko Beam Elements
No full textThis paper presents an approach for constructing field-consistent Timoshenko beam elements using least-squares smoothed (LSS) shape functions. The variational basis for shear strain redistribution is thoroughly explained, leading to the derivation of LSS shape functions for linear, quadratic, and cubic Timoshenko beam elements. These elements are then applied to linear static analysis, bifurcation buckling analysis, and free vibration analysis of prismatic and tapered beams. Numerical tests demonstrate that the LSS-based beam elements effectively eliminate shear locking and provide accurate, reliable results. Their performance is comparable to the discrete shear gap technique but with a simpler implementation procedure. The LSS shape function approach offers a practical and efficient alternative for achieving field consistency in Timoshenko beam elements, with potential applications in enhanced finite element methods (FEMs) such as isogeometric FEM and Kriging-based FEM
Performance Evaluation of Simple Regular Buildings using FBD and DDBD Methods with a Consistent Target Drift
No full textThe Direct Displacement Based Design (DDBD) method, proposed by Priestley, is an alternative to the traditional Force-Based Design (FBD) method for earthquake-resistant design. This study compares the performance of 4-story and 12-story buildings designed using both FBD and DDBD with the same target drift of 2%. The differences in base shear used for the design of the two approaches are discussed. To evaluate the buildings' performance, Nonlinear Dynamic Procedure (NDP) analysis, or nonlinear time history analysis, was conducted considering 500 and 2500 years return period earthquakes. The results indicate that the actual drift of both designs deviates from the target drift; however, the observed drifts remain within the maximum limits set by FEMA 356. Moreover, plastic damages were observed in unexpected areas of the columns, suggesting that the strong-column weak-beam design concept, as stipulated by building codes, does not entirely prevent damage to columns
KONTROL LAMPU PJU YANG DISUPLAI SOLAR CELL DENGAN ARDUINO
No full textSolar cell berfungsi untuk menangkap cahaya matahari yang akan diubah menjadi energi listrik melalui proses photovoltaic. Listrik yang dihasikan oleh solar cell langsung disimpan di dalam baterai. Saat solar cell bekerja (mengecas), tegangan solar cell dinaikkan maka kondisi relay dalam keadaan tertutup dan baterai dalam proses diisi. Jika proses pengisian energi dari solar cell ke baterai sudah penuh maka kondisi relay dalam keadaan terbuka secara otomatis. Sistem charging/discharging dan on / off lampu PJU menggunakan 2 relai yang dikendalikan oleh microcontroller yaitu Arduino Mega yang menerima, mengelola, dan mengirim data dari pembacaan sensor. Hasil dari pembacaan akan ditampilkan pada LCD yang telah terpasang. Pengujian dilakukan dengan melakukan beberapa percobaan yaitu dengan mengambil data pengisian menggunakan solar cell untuk sistem charge/discharge. Secara keseluruhan alat yang dibuat dapat bekerja dan berfungsi sebagaimana yang diharapkan tetapi kekurangan alat ini adalah menggunakan solar cell dimana daya pengisiannya kecil saat musim hujan. Berdasarkan perhitungan analisa kecukupan dibutuhkan minimal panel surya 135 Wp untuk dapat memenuhi kebutuhan energi lampu PJU dan membuat baterai tidak terkuras habis yang dapat merusak komponen baterai
Supplier Selection and Order Allocation in A Pharmaceutical Wholesaler
No full textSupplier selection is essential for any organization , as it plays a significant role in enhancing productivity. This study focuses on a local pharmaceutical wholesaler (PW) company, which places orders with other local PWs to meet its demand. Typically, pharmaceutical companies rely on multiple suppliers to satisfy their needs. However, due to an inadequate evaluation of supplier criteria, a Multi-Criteria Decision Making (MCDM) approach has been implemented to assist the PW in selecting superior suppliers and ensuring an efficient selection process. A key issue in this case study is the lack of a structured method for assessing supplier criteria, resulting in a subjective and lengthy selection process. The criteria for supplier selection encompass quality, flexibility, price, delivery, service, and supplier profile. Furthermore, alongside supplier selection, optimizing order allocation is essential for reducing purchasing costs while maximizing supplier scores. This research proposes a model designed to aid PW in addressing both supplier selection and order allocation challenges. The MCDM framework commences with the Best Worst Method (BWM) to establish the weight of each criterion. These weights then serve as input for the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), which ranks and prioritizes suppliers based on their evaluation scores. Subsequently, the results from TOPSIS inform the determination of optimal order allocation through a Multi-Objective Optimization (MOO) method. As part of the system modeling, a sensitivity analysis was performed to explore the effects of specific parameters on the objective function and decision variables, assessing variations in inventory costs, shortage costs, and demand. The findings indicated that only the demand parameter had a significant effect on decision variables, particularly regarding inventory levels and shortages. This research offers a comprehensive solution for the PW to tackle supplier selection and optimal order allocation. By employing MCDM and multi-objective optimization strategies, the company can achieve lower purchasing costs while selecting optimal suppliers based on their evaluation scores. The optimization model presented has dual objective functions: minimizing costs and maximizing total supplier value. Consequently, the model achieved a total purchasing cost of Rp. 340,196,740 and a total supplier value of 5,265,032
