Abstract

The global financial crisis that occurred at the end of 2008 have an impact on the world economy in 2009. The crisis is caused by a number of large financial institutions experiencing financial difficulties as in the USA, Europe and so on. Due to the high risk of investing in countries in crisis, then investors more confidence to invest in emerging markets countries. The purpose of this study was to observe the effect of capital inflows on economic growth in Indonesia 2001-2012 period. This study uses annual time series data from Indonesian Central Banks (BI) and the central statistical burue (BPS). The model used in this study was a simple linear regression method. The conclusion is the regression of the gross domestic product (GDP), foreign direct investment (FDI) and portfolio investment (PI) have a positive and significant on GDP. The magnitude of the effect that the (R2) FDI is 96% and the rest is explained by other factors outside the model. While PI of 92,4% and the rest is explained by other factors outside the model. The regression result previously FDI and PI previous year to economic growth, show that both have a positive effect on economic growth in Indonesia during the period of study. The magnitude of the effect that the (R2) FDI the previous year was 47,9% and the rest is explained by other factor soutside the model. While the effect of PI previous year amounted to 59.7% and the rest is influenced by other factors outside the model.Keywords : Capital inflow, Gross domestic product (GDP), economic growth.

Abstract

Black Soldier Fly (Hermetia illucens) or BSF is commonly used in food industry as a meat substitute to reduce food waste and environmental pollution. It could grow effectively using organic material such as manure and food waste. In this study, a comparison of the nutritional content of BSF fed with manure and food waste will be determined by conducting a systematic review and meta-analysis. The information about protein, fat, carbohydrate, ash, and calcium content of manure or food waste fed BSF from various scientific database sources was analyzed and discussed. There were 720 literatures selected to be included in the meta-analysis dataset, with the main selection criteria: original research articles published in the last ten years with nutritional data on manure and food waste fed BSF. From the literature screening process, 8 articles were obtained and included in the meta-analysis. Based on meta-analysis, it was found that the food waste fed BSF group has approximately 16% higher protein content, 33% higher fat content, but 59% lower ash content if compared to manure fed BSF group. However, the use of food waste as BSF feed did not give a significant effect on BSF carbohydrate and calcium content when compared to manure fed BSF.

Abstract

Graft tunnel healing is important for the successful reconstruction of the anterior cruciate ligament by using the hamstring tendon autograft. There are studies that intra graft tunnel Bone Marrow Mesenchymal stem cells (BMSCs) or intra graft tunnel Vascular endothelial growth factor (VEGF) accelerated graft tunnel healing. This study aimed to investigate the effect of using BMSCs+VEGF injected intra-articular on graft tunnel healing. We reconstructed the anterior cruciate ligament (ACL) of 12 rabbits using an autograft hamstring tendon with and without intra-articular BMSCs+VEGF. Histological evaluation was done at 3 and 6 weeks after ACL reconstruction. On the surface between the graft and the bone tunnel obtained collagen fiber thickness or Sharpey fiber is significantly more than the control group (p< 0.05) in the evaluation of 3 weeks and 6 weeks either side of the tibia and the femur. To evaluate the progression of the treatment, treatment group and control group gained progression had significantly when compared to 3 weeks and 6 weeks. It can be concluded that intra-articular injection of VEGF+BMSCs can accelerate the integration of the graft tunnel from histology evaluation on 3 and 6 weeks.

Abstract

Objectives: Following the concept of smart hotels, this study aims to analyze the relationship between technology readiness, amenities, perceived usefulness (PU), perceived ease of use (PEOU), and visiting intentions. In addition, this study seeks to identify specific elements of technology amenities that significantly influence guests' intention to visit. Thus, this study is expected to fill a gap in the literature and propose a more comprehensive conceptual framework for understanding guest behavior in the context of smart hotels.Methodology: This study used quantitative research methods with the unit of analysis being visitors to five-star hotels in Jakarta. Purposive sampling was used to select participants who met the research criteria, resulting in a total of 290 respondents. Data collection was conducted using an online questionnaire distributed through social media. Data analysis techniques used in this study included Partial Least Squares - Structural Equation Modeling (PLS-SEM) to test the relationship between variables.Finding: The results indicate that technology amenities significantly affect PEOU, PU, and visiting intention. Meanwhile, technology readiness affects PEOU and PU but does not directly influence visiting intention. PU and PEOU mediate the influence of TR and TA on visiting intention, indicating that perceptions of ease and usefulness are the main mechanisms that bridge the relationship between technological factors and consumer behavior.Conclusion: This study concludes that technology amenities have a significant effect on PEOU, PU, and visit intention. Meanwhile, technologyl readiness affects PEOU and PU but does not directly affect visit intention. PU and PEOU become mediating variables of the effect of TR and TA on visit intention.
