Technopreneurship represent a form of entrepreneurship that emphasizes entrepreneurial skills and technology. Studies on technopreneurship have been conducted, but research investigating antecedents of technopreneurship based on the entrepreneurial event model (EEM), is still limited. Most research on technopreneurship is dominated by the use of the theory of planned behavior (TPB). Therefore, this study aims to investigate the driving factors in EEM, namely perceived desirability, propensity to act, and perceived feasibility to technopreneurship intention. In addition, another purpose of this study is to explore technopreneurship intention towards technopreneurship commitment. To achieve this goal, the study used quantitative research design, primary data sources, and data collection methods using questionnaires. The sample in this study amounted to 240, with the sampling method using purposive sampling. Reliability, validity, and hypothesis testing using Smart-PLS software version 3. The results showed that perceived desirability affects technoprenurial intention, propensity to act affects technoprenurial intention, perceived feasibility affects technoprenurial intention, and technoprenurial intention affects technopreneurial commitment.

The purpose of this paper is to gift a visualization of three-dimensional (3D) trees using L-System that has been researched before. In this research, he succeeded in making a two-dimensional (2D) tree visualization and stated that when the iteration value or iteration value is larger than five, the 2D tree model results from associate iteration, it lost detail from the branch. This research is to develop the research results, namely the transformation from a 2D tree to a 3D tree. This research is intended to see what is needed in the transformation process from a two-dimensional tree to a three-dimensional tree using the L-System approach. The experiments carried out in three steps, the first step performing a two-dimensional visualization of the grammar origin from the previous research, the second step carrying out a three-dimensional transformation, and the third step making grammar modifications so that the 3D tree becomes realistic. The test results show that mathematically there are differences in the depiction of geometry in the cartesian coordinate with three axes, namely the x, y, and z axes, causing the transformation process from two-dimensional to three-dimensional trees to expand the use of symbols in the L-System. The extended production rules give more complex and more refined geometric shapes. © 2020 IEEE.

The COVID-19 pandemic has an impact on decreasing demand for beef. This condition affects the accumulation of beef stock, which impacts the return of beef products from retailers to distributors. This study aims to develop a model that can reduce risk and optimize costs resulting from returned products. Reverse logistics is a widely used method of handling returned products adding value to the product. In this study, reverse logistic activities are carried out by creating a mathematical model to maximize the product control function by creating a product inspection schedule and a product repair schedule. The formulations used PILP, and the formulations were tested using the LINGO 17.0 software. This study produces a robust model of the change in the amount and quantity of labor returned products and product quantity models with category R. From this study; it is also found the reasons why customers return the delivered meat, namely specifications, product quality, packaging, delivery process, and labor.

The aim of this study is to obtain an essential oil from Allium cepa L. var. aggregatum by the extraction process using the microwave hydrodiffusion-gravity method. The operating parameters are drying pre-treatment, material size, microwave power, and extraction time. The optimal parameter conditions were determined by screening the data using a full factorial design and subsequently optimizing the process using a face-centered central composite design. The oil yield initially increases with the extraction period and then reaches a plateau, showing no further increase. The moisture content reduction resulting from drying methods has a direct impact on the production of essential oils, leading to increased yields. The results show that the highest yield achieved is 2.78 percent, which occurs for a duration of 75 minutes, a power level of 600 W, and a material size of 1 cm. In addition, the onion oil extract also contains cyclohexanol, 5-methyl-2-(1-methylethenyl) and Z-sitral. © 2024, The Authors. All rights reserved.

The objective of the research was to analyze the clustering method by optimizing Particle Swarm Optimization (PSO) in the case of measles immunization for children under the age of 5. The research data source used is the North Sumatra Province Central Bureau of Statistics (https://***/). The data used in 2019 included 33 records with variables BCG, DPT-HB3/DPT-HB/Hib3, CAMPAK (MEASLES + RUBELLA), POLIO 4 and HEPATITIS B. The methods used were k-medoids and PSOs. This method is used to determine the value of the Davies Bouldin Index (DBI) before the cluster value is determined (k). The resulting k values were compared to k-medoids without PSO. The best results of k-medoid and PSO will be tested by classification to see the accuracy value of the cluster formed. The results showed that the optimization of k-medoids and PSO was better with the number of clusters (k = 5) than 0.078. (DBI). The results also show that the accuracy of the cluster formed is 95% with a correlation of 0.98. © Published under licence by IOP Publishing Ltd.

Much damage to buildings occurs in areas that have soft soil layers due to the failure of the foundations. Besides, foundations in soft soils generally require very expensive construction. For this reason, proper research needs to help develop strong foundations that can be used on soft soils with relatively low cost. In this research, foundations with various diameters and depths were tested on soft soil. The foundations were made of PVC pipes with diameters of ½ ", 1", 2 " or 2.5" and the same depth. Soft soil in the form of clay with particle-sizes that passed filter No. 200 was used. Before testing the foundations, carrying capacity analysis was done using the classical method on each pipe with a closed head so that the optimum carrying capacity of each foundation (PVC Pipe) was known. From this test the influence of the size of the foundations on the carrying capacity of soft soil could be seen. The results of this research will help reduce building loss/damage in areas dominated by soft topsoil © 2020 The Authors, published by EDP Sciences.

Artificial Intelligence Research in Agriculture has grown so common, and the potential they provide is so revolutionary that it is considered essential for competitive growth. Until we conducted this research, only 1064 academic documents on Trends of Artificial Intelligence Research in Agriculture that we found from 2012 to 2021 were obtained by searching the Scopus database. This study uses bibliometric analysis methods to map scientific publications worldwide. We use an article selection process, the year limitation, then the database is exported to RIS and CSV format files. Researchers in the United States had the most published articles and were indexed by Scopus among the most prolific authors ($\mathrm{N}=287$), followed by the United Kingdom at second ($\mathrm{N}=139$) and Italy with 66 academic publications. Data analysis reveals an increasing trend in the number of Trends of Artificial Intelligence Research in Agriculture publications worldwide, as measured by the Scopus index. © 2022 IEEE.

One of the critical issues of using chlorophyll (Mg-Chl) as a dye photosensitizer in DSSC is related to a rapid decay of this material. Changing the alkali metal using transition metal ions could theoretically increase the stability of chlorophyll. In this research, the substitution of Mg2+ with Mnn+ ions (n = 2 and 4) in chlorophyll structure isolated from Gliricidia sepium leaves had been carried out. The column chromatography technique was chosen to separate the chlorophyll followed by modifying the metal centre using two different compounds containing manganese, namely MnCl2 and MnO2. The results show that there are differences in Rf values after substitutions, [0.90 (Mg-Chl), 0.81 (Mn2+-Chl), and 0.96 (Mn4+-Chl)]. The Soret bands experience a redshift from 330 to 338 nm for Mn2+-Chl and a blue shift from 411 to 401 nm for Mn4+-Chl while the Q band has a redshift from 665 to 668 nm for Mn2+-Chl but a blue shift from 665 to 526 nm for Mn4+-Chl. The obtained products have similar IR absorption patterns to Mg-Chl but differ only in its transmittance with slightly higher wavenumbers shifts. Shifting of UV-Visible and Infra-red characteristics indicate different molecular electronic nature of the obtained compounds. This implies successful substitution for the metal centre without damaging the structure of the chlorophyll. © 2021 Institute of Physics Publishing. All rights reserved.

This paper considers parameters and sampling time identification of a three interacting tanks system. A novel tailor-made model is introduced to deal with the real plant in the laboratory. Experimental data are then exploited to perform parameter identification via particle swarm optimisation (PSO) method. In addition to the system parameters, we propose to simultaneously optimize the sampling selection in the optimisation process. Even though several well known sampling time selection are established, a more precise selection is required. It is shown in this paper that a meta-heuristic optimisation method (PSO) can be an efficient procedure for this problem. Moreover, three different error measures for performing optimisation are also discussed.

Molten salt has attracted the attention of researchers, especially as a coolant because of its characteristics. This study aimed to analyse the transient and steady-state of the natural circulation system in the molten salt loop with vertical heater and horizontal cooler using computational fluid dynamics. The computational fluid dynamics module in the COMSOL Multiphysics software was used to solve governing equations. Experimental data from several references were used as input data in modelling. The loop was modelled as a rectangular loop with Inconel 625 as the pipe material and molten salt (NaNO3+KNO3) as the working fluid. The variation of heater power was also carried out in modelling. The modelling results showed a good agreement with the experimental results. The results provided that the molten salt natural circulation loop with vertical heater and horizontal cooler showed good flow stability without reversal of flow direction. © Published under licence by IOP Publishing Ltd.
