Abstract

The aim of this paper is to understand the repurchase intention of customers in online shopping. The Covid-19 pandemic has caused transactions through online store Tokopedia grew rapidly. Online stores expect an increase in repurchase intention. This study investigates the relationship between perceived benefits (convenience, product selection, and price) and perceived risks (delivery, product performance, return policy and characteristics) on repurchase satisfaction with customer satisfaction as a mediating variable. Data collected from 100 respondents were analyzed using Partial Least Square-Structural Equation Modeling using the SmartPls program. This study shows that customer satisfaction, product selection, price, delivery, product performance, and return policy are significant positive predictors of customer repurchase intention

Abstract

Shrimp is one of the prima donnas of Indonesia's mainstay exports from the fishery sector which needs to be improved both in terms of quality and quantity. The use of aerators as an effort to improve the quality and quantity of harvest used by pond farmers today generally still uses a manual system, where the operation of the aerator is still based on experience, not from the quality of dissolved oxygen in the pond needed by fish or shrimp in the pond. In this study, the application of an aerator to improve the quality of dissolved oxygen both in quality and quantity, is equipped with an IoT (Internet of things)  method that can instruct the aerator to operate as desired using a smartphone.  The components used in this tool consist of solar cell panels  as renewable  power plants, Aerator Pumps, and ESP8266 WiFi. In this data collection activity, in fluctuating weather conditions. Especially during rainy conditions, data retrieval is paused because test conditions do not allow it to produce a current data reading of 0 amperes. From the logger data recording,  it can be seen that the highest current value that can be absorbed through solar panels is 2.40 Amperes obtained on day 3 of testing

Abstract

This study aims to analyze efforts to measure sociologically the emergence of terrorism in Indonesia, as well as the development of terrorism and its prevention. As well as aiming to see in more detail the formation of the National Counterterrorism Agency (BNPT) has more comprehensive steps in preventing terrorism in Indonesia. This research uses descriptive qualitative. The research approach uses library research which obtains secondary data which includes literature books, laws and regulations, official documents and others. The results of this study indicate that, apart from making arrests, the BNPT also conducts research, coaching and integration of former terrorists into society, with a deradicalization program for both former perpetrators and potential potential perpetrators. Anti-terrorism campaigns are also carried out in schools. In this writing, the writer uses an empirical juridical approach and a sociological approach to understand the culture of society. The results of this paper are that terrorism has many dimensions, namely local dimensions, regional dimensions and global dimensions. To overcome the sociological roots of the emergence of terrorism in Indonesia, to overcome this requires the cooperation of all parties, the government, the community and the international world, because the action to overcome it is not by using repression so that it can violate human rights, but also using a socio-cultural approach by inviting all components including religious leaders so that the seeds of terrorism that exist in society can be minimized, and cutting the roots of its development, the growth of understanding of radicalism in common life

Abstract

Rice husk (Oriza sativa L.) was studied in three products, namely charcoal briquettes, activated charcoal and liquid smoke. Aims to know and analyze the characteristics of the three products. Making charcoal briquettes through the forming process of rice husk charcoal powder then tested for density, moisture content, compressive strength, volatile matter, ash content, fixed carbon content, and heating value. Rice husk charcoal powder activated by soaking for 5 hours in 5% hydrochloric acid (HCl) then tested for its adsorption on spills of used lubricant. Liquid smoke from rice husk is obtained by pyrolysis process and multilevel purification and then the yield, pH value, specific gravity, and color are measured. Rice husk charcoal briquettes had the following values: density 0,601 g/cm3, moisture content 5,596%, compressive strength 8,665 kg/cm2, volatile matter content 25%, ash content 31,8%, fixed carbon content 43,2% and heating value 4.477 cal/g. Rice husk activated charcoal has an adsorption capacity of used lubricants up to 3,27 times stronger than activated charcoal with a fixed carbon content of 44,5%. Grade 3 rice husk liquid smoke has a yield value of 8,40%; pH 4,27; specific gravity 0,997; and black color. Grade 2 has a yield value of 5,20%; pH 3,41; specific gravity 1,003; and light brown. Grade 1 has a yield value of 3,87%; pH 3,24; specific gravity 0,997; and clear white color

Abstract

Academic procrastination is a procrastination behavior characterized by doing unimportant things instead of prioritizing more important tasks or activities. One of the triggers for academic procrastination is low self-regulation in learning. This can be minimized by providing training. The purpose of this research is to look at the effectiveness of self-regulated learning training on student procastination. The training participants were 55 students of SMP Muhammadiyah 5 Reinforcement who took part in the Muhammadiyah Boarding School (MBS) program. Data analysis using paired sample t test. The study used the pre-experimental design method in the form of one group pretest-posttest. The result is that there is a difference between the pretest and posttest of academic procrastination after being given self-regulated learning training, with a large effect of -0.426 which is included in the moderate category. It can be concluded that self-regulated learning training is effective in reducing academic procrastination

Abstract

Rain is a very important factor in the availability of water for planting. Farmers still use the traditional way of determining the planting schedule. This determination is considered less than optimal. This study aims to analyze rainfall on potato production in South Tapanuli Regency based on rainfall data, and determine the relationship between rainfall and the suitability of sweet potato crops. The research method used is a survey method and literature review. This type of research is a survey method with a correlation and descriptive approach to see the relationship between rainfall and potatoes used with correlation. From this research, the results of correlation and regression analysis of the rainfall variable on the potato productivity variable for the last 10 years were obtained from the Central Bureau of Statistics for South Tapanuli Regency, which illustrates a weak positive effect

Abstract

Pineapple plant is a plant that is often found throughout Indonesia, so that the production of pineapple is very abundant. Pineapple leaf fiber which consists of about 70-80% cellulose provides high modulus and strength properties, this causes pineapple leaves to be used as an efficient reinforcement of natural fiber composites. In this study, the material used was pineapple leaf fiber which had been alkalized in the direction of 0°, 45°, 90° with a volume fraction of 50% with alkalization (NaOH) treatment for 1 hour and 2 hours, without treatment. This study used polyester resin as the matrix with the hand lay up method. The test results for the pineapple leaf fiber composites which have been alkalized with variations in direction 0°, 45°, 90° with a volume fraction of 50%. And the highest value in the tensile test with treatment is in the 0° direction with a value of 5.883 MPa and an average value of 4.306 MPa with 2 hours of immersion and for the bending test the highest value is in the 0° direction with a value of 3.922 MPa and an average value of 3.276 MPa with 2 hours immersion. The 0° fiber direction has the best stress because the fiber direction is directly proportional to the static load given to the tensile and bending testing machine. Conversely, the direction of 90° is inversely proportional because the direction is not the same as the static load that is given
