REAKSI PASAR MODAL INDONESIA TERHADAP PERISTIWA PERANG DAGANG AMERIKA SERIKAT DAN CHINA

This research is an event study which aims to analyze the reaction of the Indonesian capital market, especially on LQ45 shares before and after political events that occur abroad. The event that became the object of observation was the trade war that occurred between the United States and China by using 12 events related to trade wars starting from 2014 to 2019, using the abnormal return indicator. The sample in this study are companies that are in the LQ45 stock index. The data used is secondary data in the form of the company's daily closing price and the Composite Stock Price Index (CSPI). The statistical test used to test the research hypothesis is the paired t-test which was tested on 11 events, and there was 1 event using the Wilcoxon test. The results showed that the trade war between the United States and China did not result in a significant difference in abnormal returns on LQ45 stocks with the observed period. So it can be said that the Indonesian capital market did not react to the 12 events of the trade war between the United States and China

Transport of a methamphetamine surrogate through painted drywall and accumulation in insulation

Methamphetamine is a drug of abuse in the United States and it is frequently produced in residential meth labs. During a specific cooking stage called salting out , a high concentration of methamphetamine is released into the air and can accumulate on and within indoor surfaces. Even after remediation, methamphetamine and other chemicals can be released into the occupied space by diffusion and desorption from insulation and painted drywall. To better understand the emission characteristics of methamphetamine, the diffusion coefficient of n- isopropylbenzylamine (NIBA; an isomer and surrogate for methamphetamine) was measured in latex painted drywall. To quantify the diffusion coefficient, the flux of NIBA through a painted drywall specimen was measured using a modified cup method and a flow-through chamber. Water was used as a control to validate the method. The steady state effective diffusion coefficient of NIBA for painted drywall was found to be 2.1 ± 1.4 x 10⁻⁷ m²/sec and the estimated effective diffusion coefficient of paint was e.0 x 10⁻⁹ m²/sec. Also measured was the partition coefficient of NIBA to two different types of cavity insulation. Accumulation and release of methamphetamine was simulated using a mass balance model of wall cavities and an entire house. For an illegal lab that operates continuously for 2 weeks in a small house, greater than 10 grams of methamphetamine can accumulate behind walls in the cavity insulation. It would require several months to years to deplete this reservoir if the accumulated methamphetamine is emitted at rates resulting in safe indoor concentrations. During the initial period following the cooking activity the daily dose for an adult can start as high as 120 µg/kg/day and decreases for months until it reaches a safe dose --Abstract, Page iii

Factors of Design Errors in Construction Project (A Review)

Design is an important step in construction project. Errors in design cause failure in construction stage as well as the project development. Misunderstandings of design concept between parties lead to design errors that able to decrease the quality of construction works, and also cause cost overruns and project delays. Design errors also contribute to engineering failures, which can result in accidents and loss of life. Preventive actions in reducing the errors are necessary. In accordance with these issues, this research is conducted with main purpose to identify the causal factors of design error. Review to previous studies with main topic of design error was taken in order to identify the causal factors. The factors were then validated in an oil and gas industry through observation in design process and also interview to parties whom have experiences in design process. Based from research, it is found that there are 5 main causal factors. The factors are man, method, material, machine, and environment. There are also several factors that are less in accordance with the conditions in the field such as cognitive dissonance, competitive tendering, and adversarial attitudes. By knowing the cause of the design error, can be done to prevent the effort of guarantee project sustainability

Collaborative Decision for Building Energy System on Traditional Markets in Urban Areas

It becomes more important to design energy-efficient for buildings. This is true in relationship to a public building design especially retail property such as traditional market. It calculates the use of energy during construction and operation. There are three alternatives for a building energy system which are passive energy, electrical equipment, and user processes. The alternatives are developed for a public commercial retail. They were selected by four stakeholders named government, tenant, designer, and property manager. It is not easy to make a decision where there are many stakeholders' interests. A decision support system is necessary. The system should support a collaborative process among decision makers. This paper presents a multi criteria and multi person decision process to develop agreement options and coalition formation to find the best fit option of the energy system for traditional markets building in urban areas. There are three stages involved in the process which are first is determining and scoring of every alternative for every stakeholder, second is determining the optimal solution (payoff optimum) for each stakeholder in a coalition, and third is analyzing the best fit options for every coalition and grand coalition. An analytical hierarchy process (AHP) based on satisfying option is applied for the first stage. A liner programming is used to determine payoff optimum in the stage two and an agent system based on game theory built the coalition algorithm on the stage three. The result shows a model of collaborative decision to select a building system at design process

KUALITAS FISIKA DAN KIMIA KOMPOS ECENG GONDOK (Euchornia crasipess) MENGGUNAKAN AKTIVATOR EM-4

ABSTRACT: This study aims to determine the quality of water hyacinth compost in physical and chemical properties. Water hyacinth is considered a weed that damages the aesthetics and aquatic environment in the  Lut Tawar Lake  tourist area. A solution is needed to overcome these problems, one of which is composting. In order for composting to take place faster, an EM-4 activator will be used which will give good quality. This research method uses one replicate with three treatments (K1 and K2 using EM-4, and K0 without EM-4). This study was conducted in two stages, that are the composting and characterization stages. The composting process is let runs for 60 days. Checking every 5 days is turn upside down and physical observation. After the composting process, is determined the pH, temperature and characterization. Characterization is done to determine the levels of C, N, P, K, Ca and Mg. The results of this study showed that EM-4 is effective for carbon (C), phosphorus (P) and calcium (Ca) grade. The grade of macro nutrient (C, N, P, K), micro nutrient (Ca) and  temperature of water hyacinth compost are suitable with SNI

Physical and Chemical Characteristics of Organic Packing Materials of Soil, Compost, and Rubber Leaf Litter for Ammonia Biofiltration

Ammonia odor released from many industries to environment can be treated by biofiltration. The physical and chemical characteristics of packing materials affect to biofilter in degrading the target pollutant.  The objective of the research was to characterize the physical and chemical characteristics of organic packing materials such as top soil, compost, and rubber-leaf litter on ammonia absorption and to determine the best composition of top soil, compost, and rubber-leaf litter on the characteristics of ammonia absorption.  The packing materials were crushed and screened to pass a 60 mesh screener.  The single and mixture of packing materials have been characterized to physical characteristics (density and porosity) and chemical characteristics  (moisture content, pH, C/N ratio, water holding capacity (WHC), ammonia absorption capacity (AAC), and ammonia holding capacity (AHC)).  Organic packing materials such as soil, compost, and rubber-leaf litter are nutrient-rich materials and capable in absorbing ammonia physically and chemically, so it will be very useful in the application as a packing material for biofilter.  The best physical characteristics was rubber-leaf litter, and the best chemical cahracteristics was compost.   The composition of  soil, compost, and rubber-leaf litter by weight at 1:2:2 was the best performance.
