Abstract

The price of oil fuel continues to rise, decreased supplies oil at the other side, those two factors motivate researchers to conduct research related to the efficient use of fuel. Have been made three types of fuel oil which the principle of an electromagnet used a filter, all three made of the coil with a convolution wire as many as 5000 a convolution and diameter of the nucleus of a coil 44.5 mm, 28.5 mm and 17.5 mm, a filter tested in a diesel engine. Testing done in the rpm the ignition is started 1100 until 1700 rpm, by opening throttle % to 60 % from 30%. Testing first one was done by making constant round of 1500 rpm and openings throttle vary from 30 % to 60%, next testing done with the variation of rpm start 1100 rpm until 1700 rpm by making constant valve as 40 % and of 60 % . The purpose of the variations to obtain optimum result against consumption of material fuel ( sfc ) the most little uses. Testing was done in a laboratory material.

Abstract

This study aims to examine the forms of Sundanese language interference with Indonesian in the speech of bilingual communities in Bantarwangi Tourism Village, Serang Regency. Language interference is a common phenomenon that occurs in bilingual or multilingual communities, where elements of the first language (L1) influence the use of the second language (L2), both consciously and unconsciously. This phenomenon is important to study because it can impact the quality of communication, understanding of meaning, and the development of community language skills. The method used in this study is a qualitative descriptive method with data collection techniques in the form of participatory observation, in-depth interviews, and documentation of community speech. Data analysis was carried out through the stages of data reduction, data presentation, and drawing conclusions. The results of the study indicate that the interference that occurs covers various linguistic aspects, such as phonology, morphology, syntax, and lexicon. Examples of interference include pronunciation influenced by Sundanese accents, the insertion of Sundanese vocabulary into Indonesian sentences, and sentence structures that resemble Sundanese patterns. Factors causing interference include the intensity of Sundanese language use in daily life, educational background, and community attitudes towards both languages. These findings demonstrate that interference is a complex linguistic phenomenon and a reflection of the social and cultural identity of local communities. Therefore, efforts to improve Indonesian language literacy contextually are needed, without neglecting local cultural values
