Abstract

In daily life, cooking oil has a very important role. Cooking oil itself has a usage limit. If the cooking oil has a rancid smell and turns brown, the cooking oil is not suitable for reuse. Naturally, cooking oil can only be used 2-3 times. To extend the life of cooking oil and improve its quality so that it can be reused, an adsorption process is carried out to adsorb harmful substances in used cooking oil. In this research, Ampo adsorbent is used which has the advantage of being environmentally friendly and edible. The procedures carried out in this study include the initial analysis of used cooking oil, activation of the Ampo as an adsorbent, the adsorption process by varying the mass of Ampo 70, 75, 80, 85, 90 grams and stirring time of 30, 60, 90, 120, 150 minutes and analysis of peroxide value on the adsorbed used cooking oil. The optimal condition of the research is that for the adsorption process using Ampo as adsorbent on used cooking oil, namely by stirring for 60 minutes and Ampo mass of 75 grams. This condition can reduce the peroxide value by up to 93%. While the maximum adsorption power of the Ampo adsorbent was obtained from the proving of the Freundlich isotherm equation theory with a value of 14,6487 mg/gram.

Abstract

Wood powder waste is very abundant if it is allowed to rot, which can pollute the environment, therefore wood powder can be made as a material for making particleboard. As an adhesive for the manufacture of particleboard, tannins from the extraction of mangrove bark are needed. According to Paridah and Musgrave 2006, the tannins content in mangrove bark reaches 26%. According to Hamidah 2006 mangrove bark that is dried or crushed contains an average of 20 – 30 % tannins and the content of these tannins is quite high and is very good for use in various kinds of industries. The purpose of this research is to find the optimum temperature of pressing and the amount of added tannins to obtain strong particleboard following SNI. The use of tannins is expected to be an environmentally adhesive alternative. The preparation of this particleboard is done by preparing the raw materials, extracting tannin from mangrove bark using a solvent of 96 % ethanol at a temperature of 70 0C for 3 hours, after that it is continued with the process of making particleboard by mixing between wood powder and tannins with variations of 20%, 25%, 30% and 35% with previously had been mixed with formaldehyde 2% of the weight of wood powder before pressing. Mold is made with a size of 20 x 20 cm were then pressed using a hot press with a temperature of 1100C, 1200C, 1300C, and 1400C. The result obtained was tested for the expected tensile compressive strength values according to SNI where the resulting particleboard can be used for household and industrial purposes. Tannins added as much as 30 % produce the best MOR value of 7,76 kg f/cm2 while the pressing temperature of 120 0C result in the best MOR value of 7,66 kg f/cm2

Abstract

Web service is a method of connecting servers and client applications. There are several types of technology in developing a web service, such as REST and Graph-QL. Graph-QL is an alternative technology created by Facebook to correct REST technology's shortcomings, especially in the data presentation section. Graph-QL provides an alternative where the client application can determine for them what data is needed. This paper analyzes the performance of the two technologies to determine which technology is suitable for their needs. The analysis carried out is to compare the response speed and data efficiency to optimize the available bandwidth. The development model uses the waterfall model, which consists of research, design, implementation, and testing. As a test object, two Node-JS based applications were developed with the Express Framework, which applied REST and Graph-QL concepts on each test object. The results obtained are that REST has better performance than Graph-QL in its response speed. On the other hand, Graph-QL also excels in data presentation by client application requests to optimize the available bandwidth.

Abstract

The problem of flooded road infrastructure mainly occurs in urban areas, due to low soil bearing capacity, high rainfall intensity, and failure of rainwater flow to the drainage system. Flooded roads, when traversed by motorized vehicles, will be very detrimental to the rider. Flood water can damage engines, transmissions, electrical components, and motor vehicle electronic computer systems. Water is also very dangerous to car safety devices, such as airbags and braking systems that use ABS (Antilock Braking System). Also, there may be health problems involving fungi and bacteria, due to damp vehicles, especially on cars. Other problems related to water may not be immediately apparent, such as rust and corrosion, which will develop over time. The flooded road reporting system is an early warning system that provides information to road users so they can take anticipatory steps. This research proposes a crowdsourcing-based flood road reporting system, called Frostid (Flooded Road Reporting System Indonesia), that involves local road users in collecting flood information. Frostid application users can not only access geospatial information for flooded roads but also can collect location data using the Global Positioning System (GPS) and upload the location points of flooded roads using their smartphones. The Frostid application uses a navigation map to describe the location of flooded roads. Flood information stored in the Frostid application is built entirely by local road users. The Frostid application is built on a mobile Android platform.
