Abstract

B.Indonesia Turbocharger adalah sebuah kompresor sentrifugal yang mendapat daya dari turbin yang sumber tenaganya berasal dari gas buang kendaraan. Pada perancangan ini turbocharger digunakan sebagai pengganti dari fungsi compressor dan turbine[1]. Rancang bangun turbocharger gas turbine engine ini dibagi menjadi beberapa sistem antara lain; combustion chamber, oil system, fuel system, dan ignition system. Dari teori – teori yang ada pada referensi[2], penulis melakukan proses perancangan yang terdiri dari beberapa bahasan, antara lain menentukan bahan bakar yang akan digunakan, hose, valve dan nozzle. Bahan bakar yang digunakan dalam rancangan ini adalah LPG (Liquid Petroleum Gas)[3]. Hose dan valve yang digunakan pada rancangan ini menyesuaikan dengan debit fluida yaitu sebesar 6,89 × 10−3 ????3/????, kecepatan fluida sebesar 87,77 m/s, dan tekanan aliran fluida sebesar 238,88 psi. Nozle yang digunakan berdiameter 0,005 m. Dari perancangan fuel system yang penulis rancang dapat menyalurkan bahan bakar yang dibutuhkan agar dapat menghasilkan pembakaran yang optimal. B.English Turbocharger is a centrifugal compressor that gets power from turbines whose power source comes from vehicle exhaust gases. In this design the turbocharger is used instead of the compressor and turbine function. Refer to the References, the authors carry out the design process which consists of several topics, including determining the fuel to be used, hose, valve and nozzle. The fuel used in this design is LPG (Liquid Petroleum Gas). The hose and valve used in this design adjusts to the fluid flow of 6,89 × 10−3 ????3/????, the fluid velocity of 87,77 m/s, and the pressure of the fluid flow of 238,88 psi. The nozle used was 0,005 m in diameter. From the design of the fuel system that the author designed can deliver the fuel needed to produce optimal combustion.

Abstract

Events are one of the public relations activities that can be used to promote a company. In Public Relations studies, events are called special events. An event organizer is a type of business in the field of entertainment. An event organizer is tasked with organizing and designing the course of an event. PT Infia Pariwara Nusantara is a company that specializes in event activities. PT Infia Pariwara Nusantara creates its own events such as Jakarta Sneakers Day, Melodi Alam, and Fantoystic World, and also provides event, campaign and production activity services for brands. The Jakarta Sneakers Day event itself has been held by PT Infia Pariwara Nusantara since 2017 and immediately received public attention. The purpose of this research is to find out the Special event Jakarta sneakers day, the image and influence of the Special event Jakarta sneakers day on the image of PT. Infia Pariwara Nusantara. The theories used in this research are Public Relations theory, Marketing Public Relations theory, Event theory, Special Event theory, and Image theory. The conceptual approach used in this research is Lesly's special event concept, namely 5 W + 1 H and is linked to Nimpoeno's image formation theory which explains Perception, Cognition, Motivation and Attitude. This research is quantitative research with a survey method and the data collection technique used is a questionnaire. The population in this study was 34,640 visitors to Jakarta Sneaker Day and the sample used was 100 respondents using the Taro Yamane formula. The sample data collection technique in this research used random sampling. The results of this research show that there is an influence between the Jakarta Sneaker Day Special event on the image of PT. Infia Pariwara Nusantara. This can be seen from the correlation coefficient of 0.650. The magnitude of the influence of the Jakarta Sneaker Day Special event on the image of PT. Infia Pariwara Nusantara is 0.422 or equal to 42.2%. Meanwhile, the remaining 57.8% was influenced by other variables not examined in this research

Abstract

Gonggong is a type of sea snail that is commonly consumed and has become an icon of the culinary specialties of the Riau Islands Province. The most commonly recognized and consumed types in the Riau Islands are Laevistrombus turturella and Strombus canarium. These two types of gonggong have similar physical characteristics and can be difficult to distinguish. Therefore, this research was conducted to find a practical solution that can classify types of gonggong based on their visual images. This study uses a real-time object detection approach based on the MobileNet SSD framework implemented in TensorFlow and applied to an Android-based mobile application. The dataset used consists of 418 images of both types of gonggong that have been augmented with and without backgrounds. The results of the tests show that the model has a confidence level of 83% for images without backgrounds, and 67% for images with backgrounds. These findings indicate that the method used has the potential for further development to improve the model's confidence level in classifying types of gonggong.

Abstract

This study aims to describe the learning model implemented by the eighth-grade science teacher at SMPN 2 Jember for the topic of Work and Energy and to evaluate its effect on students’ motivation and understanding. The study used a descriptive qualitative approach with the researcher as the primary instrument, supported by interview guidelines and questionnaires. The subjects were one science teacher and 39 eighth-grade students. Data were collected through structured interviews with the teacher and a 4-point Likert scale questionnaire containing six items on motivation and four items on understanding. Data analysis was conducted descriptively using frequency counts and percentages. Interviews indicated that the teacher applied a cooperative learning model to enhance collaboration, interaction, and students’ social skills. Questionnaire results showed most students had positive motivation, with 42.31% Strongly Agree (SS) and 55.98% Agree (S), while 1.71% were Disagree (TS) and 0% Strongly Disagree (STS). Understanding responses were 43.59% Agree (SS), 46.79% While (S), 8.97% Disagree (TS), and 0.64% Strongly Disagree (STS). Findings confirm that cooperative learning improves engagement, enthusiasm, and understanding. This model provides an interactive and enjoyable learning experience, encouraging students to discuss and collaborate actively. Results are valuable for teachers in designing effective strategies and as a reference for further research on learning models effects on motivation and understanding.
