The power-law memory effect is taken into consideration in a generalisation of the economic model of natural growth. The memory effect refers to a process's reliance on its current state and its history of previous changes. However, the study that focuses on natural growth in economics considering the memory effect with fractional order-linear differential equation model is still limited. The current investigation seeks to solve the natural growth with memory effect in the economics model and decide the best model using fractional differential equation (FDE), namely Adomian Decomposition and Variational Iteration Methods. Also, this study assumes the level of consumer loss memory during a certain time interval denoted by a parameter (α). This study showed the model of loss memory effect with 0 < α ≤ 1 given a slowdown in output growth compared to a model without memory effect. Besides that, this study also found that output Y(t) is growing faster with the Variational Iteration method compared to the Adomian decomposition method. Also, using graphical simulation, this study found the output Y(t) is closer to the exact solution with α=0.4 and α=0.9. In conclusion, this study successfully solved natural growth with memory effect in economics and decided the best model between FDE, namely Adomian decomposition and Variational iterative methods using numerical analysis.

The production of ceramic creates scrap material that is often wasted. The aims of this study are to know the influence of size and material on scrap material and the role of accounting in managing the environment. The results show that product size and material used together have an effect on scrap material. Partial testing shows that only materials used have a positive and significant effect on the emergence of scrap materials. The accounting treatment is done by debiting Cash IDR 5,258,753.99 and crediting Work in Process-Raw Material Cost IDR 5,258,753.99. The cost of goods manufactured of ceramic products after accounting treatment for scrap material is lower than before. The selling price also decreased for the same product. The operating profit will increase IDR 5,013,038.64 (use original selling price) and decrease IDR 1,272,112.67 (use selling price after treatment for scrap material). The emergence of scrap material causes environmental problems. Environmental accounting overcomes this by removing scrap material from its place. The transfer is done by selling at a price of half the standard price. The proceeds from the sale are treated as a deduction from the cost of raw materials in an account in the Work in Process-Raw Materials Cost credit.

The Indonesian Navy is the spearhead in maintaining maritime security in Indonesian waters. In carrying out its main tasks, the Indonesian Navy has components of an Integrated Fleet Weapon System in which there are elements of Ships and Naval Bases. To ensure the effectiveness of carrying out operations by ship elements, ship operations are supported by the Naval Base as the organizer of the support function. Naval Base's carrying capacity consists of 5 (five) support functions, including: (1) support for anchoring facilities; (2) support for supply facilities; (3) support for maintenance and repair facilities; (4) support facility maintenance personnel; and (5) support for base development facilities. Naval Base does not yet have its dock to support anchoring facilities for ship operations. In addition to cooperation in the use of the Naval Base anchorage facility, there is also cooperation in port security, both in terms of land and port water aspects. As the number of ship visits at Naval Base Harbor increases, the dock utility increases. The increase in dock utility resulted in a decrease in port services which also resulted in a decrease in the Naval Base Carrying Capacity. To improve port services, Pelindo III implements the port development program contained in the Naval Base Port Master Plan in Permen KP number 792 of 2017. In this study, an analysis of the impact of the Naval Base Port development policy on the carrying capacity of the Naval Base was carried out. The data analysis uses System Dynamics modeling with a simulation period of 30 years in 3 development scenarios, namely short-term scenarios, medium-term scenarios, and long-term scenarios. From the simulation results, it is found that the construction of the Naval Base port affects the Naval Base Carrying Capacity with an average increase of 1.8% in each policy scenario. The increase in Naval Base Carrying Capacity has an effect on increasing Ship Operations by an average of 1.8% and also increasing the Security of Naval Base Harbor by an average of 0.14%. The results of the analysis of this study can be used as consideration for policymaking by the Navy.

Reinforced concrete wall critical zones are the responsive areas of dissipated earthquake loads. They are formed in the connection of the wall panels and the fixed restraints. The longitudinal and transversal steel reinforcements with certain spacing are designed according to the required nominal strength at the connections. Under certain conditions, the reinforcement distance becomes very tight, making working on castings using normal concrete difficult. This condition also occurs in boundary elements consisting of longitudinal and transversal reinforcements in tight spaces. A concrete material that flows easily and solidifies itself is required to avoid segregation. One type of this material is Self-Compacting Concrete (SCC). The SCC performance as a wall panel material that withstands gravity and cyclic lateral loads still require further research. This study aimed to analyze the hysteretic performance of reinforced SCC wall panels with variations of shear reinforcement in resisting cyclic lateral loads. The analysis used software based on numerical analysis. The drift ratios, hysteretic curves, stress patterns, ductility, and stiffness of the wall panels were analyzed. The SCC wall panel with ordinary shear reinforcement resisted lateral positive and negative loads of 152.32 kN and 143.09 kN, respectively. In comparison, the wall panel with boundary elements and tighter shear reinforcements could withstand the positive and negative lateral loads of 187.62 kN and 145.98 kN, respectively. The SCC wall panel reached the best ductility of 21.38 with ordinary shear reinforcement because the yield occurred faster than in other wall panels. The results showed that the boundary elements and shear reinforcements of reinforced SCC wall panels affected the performance in resisting cyclic lateral loads.

This study aims to explore the power of grit, personality, and creativity to enhance teacher’s professional competence with teaching efficacy mediation. A questionnaire collected the research data through the survey method. This research participant is 386 mathematics, and natural science teachers in Indonesia spread across four provinces (Jakarta, Banten, West Java, Riau) determined by accidental sampling. Data analysis uses path analysis supported by descriptive statistics. The results show that grit, personality, and creativity, had a significant effect on teacher’s professional competence, either directly or indirectly, mediating by teaching efficacy. Personality has a more dominant direct effect on teaching efficacy and professional competence than grit and creativity. Even personality also has an indirect impact on professional competence mediating by teaching efficacy better than grit and creativity. That means the existence of personality more critical than grit and creativity. Therefore, a fit research model about grit, personality, and creativity on teacher’s professional competence mediating by teaching efficacy was found based on data from teachers in Indonesia. This model can be discussed as a reference or discuss by researchers and practitioners in developing professional competence models.
