Abstract

The increasing number of buying and selling transactions through e-marketplaces today causes the need for a model that is able to measure the extent of acceptance of e-marketplace applications. The existence of a model of measuring e-marketplace acceptance will greatly help business people in that field in order to improve the performance of the service products it offers, which in this study is Lazada. This research was conducted to find out how far the user acceptance of Lazada e-marketplace applications using the Technology Acceptance Model (TAM). The approach on this research is using quantitative approach with a survey method. Data collection techniques were carried out using questionnaires that were randomly distributed to Lazada e-marketplace users. The data analysis method used is descriptive analysis using multiple linear regression data analysis techniques. The results showed that content richness, security and perceived ease of use variables had a significant effect on the perceived of usefulness variable, security variables had a significant effect on perceived usefulness variables, perceived usefulness variables, perceived ease of use and security had a significant effect on the variables customers intention to use.

Abstract

Polyester fabrics are the most popular clothing material in the textile product manufacturing process and are widely used. Small floral motifs, line or small dots that are sharp and bright (more than one color) on the basis of contrasting or dark colors usually obtained by discharge printing or resist printing, because it is not easy to do by direct printing in a large amount of production. In printing alkali discharge, polyester fabrics are used dispersion dyes that can be damaged by alkali (azo type) as the base color. Color motifs are used dispersion dyes that are resistant to alkalis (anthraquinone type) which do not have ester groups in their chromophore. The purpose of this study was to determine the extent to the influence of the concentration of using sodium carbonate 100, 150, 200, 250 g/kg paste as etching agent and fixation time 4,6,8 minutes temperature 180 °C, then testing the degree of fabric white, color difference, fabric tensile strength and color fastness against washing and rubbing. The optimum conditions were achieved in sodium carbonate 200 g/kg paste, temperature 180 °C for 6 minutes, white degree of fabric Δ K/S 0.01684, color difference value Δ E= 2,81, fabric tensile strength of 17,40 kg towards warp 18,05 kg towards the feed, fastness to washing 4-5, color fastness to wet rubbing and dry rubbing 4-5. Keywords : sodium carbonate, discharge printing, azo, anthraquinone, polyester

Abstract

The potential for the Halal Industry is enormous, both for foreign and domestic needs in Indonesia. The need for commodities with halal guarantees for Muslim countries, even in non-Muslim majority countries, continues to increase from year to year, in the form of foodstuffs, medicines and cosmetics. From 2017 to 2018 it grew to 5.1%, reaching 1.37 trillion dollars in 2018. However, Indonesia is still a consumer and not a producer. Various challenges in the halal industry and supply chain as well as challenges in the Islamic economy as a support for the halal industry become an analysis of the causes of Industrial Engineering Science with its various scientific tools can be the answer to some problems. This research will explain about the Halal Industry and Supply Chain from the scientific aspects of Industrial Engineering which includes facts and data on the halal sector, regulations and sharia economics as a support for the halal industry, the halal food sector, halal operations, halal logistics (supply chain). ) and the potential of the halal industry in Indonesia.

Abstract

The study used mahkota dewa as adsorben to decrease of the peroxide number and free fatty acids on the used cooking oil with immersion variations for 2 days dan 3 days and also concentration variations of mahkota dewa 5 % w/v, 10 % w/v, and 20 % w/v. The results of the peroxide analysis test still exceed the required number of SNI namely 10 meq O2/kg and the results of the free fatty acid analysis test in the sample with immersion and stirring time for 2 days and 3 days the concentration of mahkota dewa 20 % w/v has met the SNI, which is 1.04 % and 0.91%.

Abstract

Finance has a very important role in supporting the sustainability of a university's activities. In the current condition at the University of Bandung Raya, the number of students has decreased which will affect their income level. What is done by the university is to find as many students as possible in each available study program. Based on the results of the study, it shows that this results in a higher level of financial expenditure than income due to the small number of students who are spread across 4 existing study programs. Based on the results of the calculation, it is found that if the university will benefit based on the existing conditions, namely by only focusing on 1 undergraduate study program with a total of 150 students.

Abstract

Mount Agung with an altitude of 3.142 meters above sea level is located in Karangasem. This mountain is one of the active volcanoes in Indonesia. Some dangerous impacts caused by the eruption of Mount Agung are acid rain, earthquakes, lava/lava flow, landslides/mudflow, smoke from lava, pyroclastic, rain of volcanic ash, and rocks and also volcanic gas. One of them which is Rain of volcanic ash can cause blisters on the skin and eyes as well as respiratory irritation. For long-term effects can cause silicosis (lung disease resulting from dust) and chronic lung disease. This study was conducted to determine the Mount Agung volcanic ash eruption effect on the results of SPM concentration measurements at the Jembrana Climatology Station using comparative data and sample data obtained from SPM, VONA concentration measurement data, and the HYSPLIT Volcanic Ash (NOAA) models.
