Abstract

Some problems are attached by the online learning system such as low self-learning awareness and conceptual understanding. One of the learning approaches is the concept of heutagogy which is the development of andragogy approach. Self-learning awareness and conceptual understanding are needed either online or offline learning system, so it can improve student learning outcomes in all subjects. However, previous studies on the effect of the heutagogy approach on self-learning awareness and conceptual understanding as well as relate it to increase learning outcomes is still limited. Likewise with research on how the influence of self-learning awareness, conceptual understanding and their interaction on increasing learning outcomes has not been found. As novelty, this study aims to determine the effect of the heutagogy approach on increasing conceptual understanding and self-learning awareness and the interaction effect of self-learning awareness and conceptual understanding on course learning outcomes. This study is quasi-experiment. A total of 250 first-year students were randomly selected as samples in the pre-test and post-test. Data were collected by distributing a set of questionnaires and a set of exams via Google forms and were analyzed using Statistical Package for Social Science 23.0 (SPSS v 23.0) and SmartPLS 3.0. Findings showed that the heutagogy approach has possitive and significant effect to increase conceptual understanding and self-learning awareness. Self-learning awareness has a positive and significant effect and also mediates the effect of conceptual understanding on learning outcomes. Heutagogy approach increase conceptual understanding (8.79%), self-learning awareness (10.68%), and learning outcomes (6.70%) compared with traditional method.

Abstract

The hydration heat confined to the core of the mass concrete during the hydration reaction causes a temperature rise and irregular temperature distribution in the concrete. High temperatures in concrete cause Delay Ettringite Formation (DEF) that cause damage several years after pouring, especially if the concrete is in an acidic environment. The uneven temperature distribution causes thermal stresses that can initiate cracks in the concrete surface. This article discusses a prediction of temperature distribution inside a mass concrete used as a rotary kiln foundation. We measure the heat of hydration of the concrete sample using an adiabatic calorie meter and derive the heat of hydration equation from the measurement data. The hydration heat was used in numerical calculations to obtain the temperature distribution, maximal temperature and temperature differential. The numerical calculation shows that the maximum foundation temperature was 64.01 0C. This temperature is still below the limit temperature for the occurrence of Delayed Ettringite Formation (DEF). The core region has the highest temperature, while the surfaces have the lowest temperature. The difference between the highest and lowest temperatures is 37.40 0C. However, the temperature differential exceeds the safe limit, 20 0C, so heat treatment to prevent cracking needs to be done.

Abstract

Work accident prevention is cheaper than responding responsively after an accident. Common problems are weakness and a lack of predicted levels of risk for a job that could potentially be a work accident. Risk Control is undoubtedly something that must be designed before the work is done. This control must be supported by costs to run a Construction Safety Management System (SMKK). The initial observations and references that have been conducted and collected indicate the problem that the financing does not appear in the Budget Plan of the contractors in several construction projects when participating in the tender auction at the research site, namely: The City of Padang. There are limitations of information media, socialization, and implementation instructions become challenges in running it. This fundamental problem gave rise to an idea to carry out research. This research has been conducted to explore the problem of the level of knowledge of contractors about the financing of smkk. The data in this study was obtained by survey, in detail, disseminating questionnaires online to samples, namely: contractors in the city of Padang. The questionnaire has been analyzed, resulted the level of knowledge of this contractor is quite good in the level of knowledge about the components of the budget plan of SMKK. There is no problem with the contractor's knowledge related to the budget plan, except: readiness and planning for the system of budget.

Abstract

Ferry Ro-Ro is a type of ship used to carry passengers and vehicles. This ship has several decks such as navigation decks, passenger decks, and car decks. The car deck is subject to a heavy load as it should accommodate vehicle loads. This study aims to conduct a finite element analysis to determine the stress and deformation experienced on the car deck of the Ferry Ro-Ro and determine the safety factor based on BKI (Indonesian Classification Bureau). The method used in this study is the Finite Element Method (FEM) which has been applied in the finite element based-applications namely Ansys Workhbench. The simulations are carried out using the software by varying the thickness of the car deck’s plate, the plate is subjected to pressure loads which are car loads accommodated by the car deck. Moreover, the fixed support is applied in the deck during the simulation. Based on the simulation results of variations of 90, 100, and 110% plate thickness. It is obtained that the smallest plate experienced maximum stress and the obtained safety factor of all plate thickness variations was satisfied the BKI Standard.
