Rasio Keuangan Sebagai Variabel Prediktor Harga Saham Pada Perusahaan Pertambangan Batu Bara

Coal stocks are stocks that have been the target of investors in recent times because the price has reached its highest peak in the last ten years. This study aims to determine the effect of the variables Return On Assets (ROA), Return On Equity (ROE), Debt to Equity Ratio (DER), Gross Profit Margin (GPM), and Earnings Per Share (EPS) which also involve the growth of total assets as a control variable on stock prices, both partially and simultaneously at the coal mining companies ADRO, ITMG, and PTBA. The method used in this research is quantitative analysis with panel data regression. The data used is from 2010-2020 and involves three companies so the total observations are 30 company years. The results show that ROA, ROE, and GPM have an effect on stock prices, while DER and EPS growth have no statistically significant effect

Digital documentation in reinstating heritage significance of Melanau tall longhouse at Kampung Sok Sarawak

The Melanau tall longhouse in Kampung Sok Sarawak represents one of Malaysia’s unique vernacular architecture. Built in the late 19th century, the structures of this house are made using natural materials which are readily available from the jungle and all of these materials are known to be hardy and water resistant. Belian tree trunks are used as the main structural components of Melanau tall longhouse especially for the columns and the stairs. This tall longhouse is estimated to be over 100 years old, and it is the only original tall longhouse that remains today. Many traditional longhouses have been abandoned due to change in lifestyle and economic conditions thereby turning them into a threatened typology. Recognition of its historical values and adoption of a conservation management plan is crucial in the effort of sustaining this heritage asset. A comprehensive documentation is essential for the preservation and conservation of tangible and intangible aspects of the traditional longhouse. This paper presents heritage preservation efforts through the application scan to BIM method using high-definition 3D terrestrial laser scanning systems as a prerequisite in heritage building preservation and management, by capitalising on two major factors: the completeness and accuracy of data, as well as the potential of creating 3D models of the assets. In capturing as-built information, the system provides opportunities for condition monitoring and assessment; real-time quantity for ongoing operations; spatial information support for maintenance; regulatory compliance, and building forensics

Internal Illumination to Overcome the Cell Density Limitation in the Scale-up of Whole-Cell Photobiocatalysis

Cyanobacteria have the capacity to use photosynthesis to fuel their metabolism, which makes them highly promising production systems for the sustainable production of chemicals. Yet, their dependency on visible light limits the cell‐density, which is a challenge for the scale‐up. Here, it was shown with the example of a light‐dependent biotransformation that internal illumination in a bubble column reactor equipped with wireless light emitters (WLEs) could overcome this limitation. Cells of the cyanobacterium Synechocystis sp. PCC 6803 expressing the gene of the ene‐reductase YqjM were used for the reduction of 2‐methylmaleimide to (R)‐2‐methylsuccinimide with high optical purity (>99 % ee). Compared to external source of light, illumination by floating wireless light emitters allowed a more than two‐fold rate increase. Under optimized conditions, product formation rates up to 3.7 mm h(−1) and specific activities of up to 65.5 U g(DCW) (−1) were obtained, allowing the reduction of 40 mm 2‐methylmaleimide with 650 mg isolated enantiopure product (73 % yield). The results demonstrate the principle of internal illumination as a means to overcome the intrinsic cell density limitation of cyanobacterial biotransformations, obtaining high reaction rates in a scalable photobioreactor

Photobiocatalytic Oxyfunctionalization with High Reaction Rate using a Baeyer-Villiger Monooxygenase from Burkholderia xenovorans in Metabolically Engineered Cyanobacteria

Baeyer-Villiger monooxygenases (BVMOs) catalyze the oxidation of ketones to lactones under very mild reaction conditions. This enzymatic route is hindered by the requirement of a stoichiometric supply of auxiliary substrates for cofactor recycling and difficulties with supplying the necessary oxygen. The recombinant production of BVMO in cyanobacteria allows the substitution of auxiliary organic cosubstrates with water as an electron donor and the utilization of oxygen generated by photosynthetic water splitting. Herein, we report the identification of a BVMO from Burkholderia xenovorans (BVMOXeno) that exhibits higher reaction rates in comparison to currently identified BVMOs. We report a 10-fold increase in specific activity in comparison to cyclohexanone monooxygenase (CHMOAcineto) in Synechocystis sp. PCC 6803 (25 vs 2.3 U g(DCW)(-1) at an optical density of OD750 = 10) and an initial rate of 3.7 +/- 0.2 mM h(-1). While the cells containing CHMOAcineto showed a considerable reduction of cyclohexanone to cyclohexanol, this unwanted side reaction was almost completely suppressed for BVMOXeno, which was attributed to the much faster lactone formation and a 10-fold lower KM value of BVMOXeno toward cyclohexanone. Furthermore, the whole-cell catalyst showed outstanding stereoselectivity. These results show that, despite the self-shading of the cells, high specific activities can be obtained at elevated cell densities and even further increased through manipulation of the photosynthetic electron transport chain (PETC). The obtained rates of up to 3.7 mM h-1 underline the usefulness of oxygenic cyanobacteria as a chassis for enzymatic oxidation reactions. The photosynthetic oxygen evolution can contribute to alleviating the highly problematic oxygen mass-transfer limitation of oxygendependent enzymatic processes

The impact of relationship lending to the cost of debt and firm performance of manufacturing companies in the Philippines from the years 2009-2013

Through the years, there have been numerous journals published on the impact of relationship lending to European Small and Medium Enterprises (SMEs), particularly those enterprises in Spain. In these papers, they found that relationship lending affects a firm\u27s cost of dbt, credit rationing, and firm performance. This study explained how relationship lending affects manufacturing companies in the Philippines. In quantifying the independent variable, ind this case, relationship lending, the researchers used the number of banks a firm deals with and the duration or the length of relationship between the two parties. The researchers used the firms\u27 cost of debt and firm performance as dependent variables. Interest expense is used as a measure of Cost of Debt, while Return on Equity and Income are used as measures of firm performance. The researchers found that there is a positive relationship between the number of banks a firm deals with and the firms\u27 interest expense. The same is true for Firm Debt and Income
