Abstract

To meet the needs of racing, both drag bike racing and road races, vehicles or motorcycles with conditions still standing are not enough. Therefore, it is necessary to modify certain parts, including modifying the chassis, body, and engine. The three parts are very related. Of the three parts, the most priority is modifying the engine because the engine is the main factor in a vehicle or motorcycle. What is needed in modifying the engine is improving engine performance or maximizing engine performance. In this study, the author chose a four-stroke kharisma motorcycle because the modification did not require many changes from the standard conditions. Drag bike racing and road racing have similarities in modifying the engine. Only the difference is in terms of calculating engine endurance. Drag bike racing does not need long engine endurance because it only drives on straight tracks, while road races must think about engine endurance because the engine works in rough terrain conditions varies.

Abstract

CV Cilacap Indah Abadi is a company established in chicken stock. This company cooperates with several suppliers and chicken breeders spread across several sub-districts in Kebumen Regency. In addition to providing farm chickens, CV CIA also provides feed and medicine. This company still uses handwritten or manual recording, causing the process of company management, especially in the inventory field, to take a long time and is less efficient. Underlying the problem above, the company needs an information system that facilitates company performance based on/using a website to store records in the database. The research results are in a website application for poultry stock systems using/based on the CodeIgniter 3.1 framework.

Abstract

Big data analytics can extract travelers' sentiment, emotions, and experiences from their internet opinions. This study analyzes sentiment, emotion, and traveler experiences at eight tourism destinations in Purwokerto Central Java, Indonesia. The methods are lexicon using NCR vocabulary(EmoLex) and word cloud analysis. The results show visitors generally have a positive sentiment. The five destinations with high positive sentiment are the Village (91%), Lokawisata Baturaden(81%), Baturaden Forest (79%), Limpa Kuwus (78%), and Taman Andang(.77%). In comparison, other destinations achieve positive sentiment under 70%. Only a few visitors give negative sentiment to all tourism destinations. The emotion of visitors stands out in Joy and Trust. NRC revealed sadness dan anger emotion but only about 20%. Cloud analysis does not reveal a distinguish keyword because the word feature still contained noise such as conjunction, adverb, and the name of the sites. Further research must consider other text preprocessing to handle noises.

Abstract

This study aims to determine the effect of modifying the Vespa Sprint I-Get 150 ABS motorcycle on power and torque. The method used is to modify the intake manifold, combustion chamber, ignition, and exhaust channels. Power and torque were tested using the Bethar Racing Team Dunamometer. The test results show that: 1) modification of the piston from 58 mm to 66 mm increases engine capacity by 200.4 cc; 2) Modifications to the intake manifold, combustion chamber, ignition, and exhaust ducts can increase power by 24.8 hp at 5122 Rpm; 3) Modifications to the intake manifold, combustion chamber, ignition, and exhaust ducts can increase torque by 41.68 Nm at 1890 Rpm.

Abstract

Information Technology Certification Center (ITCC) is a laboratory focused on Certification activities in Information and Technology. Currently, ITCC uses a manual system with Microsoft Excel for creating letter numbers, which is time-consuming and prone to data loss due to unintegrated storage. To solve this, the author developed a letter archive application using the Rapid Application Development (RAD) model, which accelerates the development process by producing incremental software versions. This application improves the efficiency of numbering and securely storing mail archives while providing a WYSIWYG editor for easy document editing
