Abstract

Local wisdom is integral to a community's cultural identity, encapsulating knowledge, values, and practices passed down through generations. The traditional game of Patil Lele, rich in cultural significance, also serves as a valuable educational tool for exploring fundamental physics concepts. This study aims to analyze the physics principles inherent in the Patil Lele game and identify optimal techniques for achieving maximum throwing distance. The research used a quantitative descriptive method; Data were collected through interviews and observations and supported by a thorough literature review. The findings reveal that the game embodies key physics concepts, including parabolic motion, Newton's laws, the moment of force, momentum, and impulse. Moreover, three effective techniques for enhancing throwing distance were identified. This research underscores the importance of applying physics concepts to enhance traditional games, enriching educational value and preserving cultural heritage.

Abstract

Pemantauan kondisi ruangan bertujuan untuk mencegah dampak buruk akibat dari udara yang tercemar, termasuk adanya gas formaldehid. Gas tersebut bisa dipengaruhi oleh kelembaban relatif dan temperatur ruangan. Pentingnya memonitor dan mengendalikan kondisi di dalam ruangan telah mendorong penggunaan teknologi sensor dan perangkat IoT untuk pemantauan real-time. Oleh karena itu, penulis akan melakukan kalibrasi sensor yang akan digunakan, yaitu sensor MS1100-P111 sebagai detektor gas formaldehid dan sensor DHT22 untuk mendeteksi kelembaban relatif dan temperatur. Kalibrasi sensor dilakukan untuk memastikan akurasi dan reliabilitas pengukuran, menggunakan perbandingan persamaan dari datasheet untuk MS1100-P111 dan metode regresi linear untuk DHT22. Setelah kalibrasi, dilakukan perhitungan nilai error, persentase error, dan rata-rata kalibrasi. Hasil perhitungannya secara berurutan adalah 0,004 mg/m³; 1,783%; dan 98,217%. Untuk kalibrasi sensor DHT22, digunakan metode regresi linear. Nilai error, persentase error, dan rata-rata kalibrasi yang diperoleh untuk kelembaban relatif adalah 0,145%; 0,279%; dan 99,721%. Sedangkan untuk temperatur, nilai error, persentase error, dan rata-rata kalibrasi yang diperoleh adalah 0,81 ; 2,25%; dan 97,75%.

Abstract

The DCDB panel is a panel for distributing direct current electricity. Inside the panel there are cables to carry current which affects the temperature of the panel. The greater the current flowing, the greater the resulting temperature. Dew that occurs on the DCDB panel can cause various kinds of electrical disturbances, so the DCDB panel must be kept dry and protected from condensation. The dew parameter is the dew point. In order to minimize the occurrence of dew on the DCDB panel, it is necessary to know the prediction or estimate of the occurrence of dew on the DCDB panel by evaluating the Rectifier room temperature with the external environmental weather temperature. Therefore, research was carried out for 10 days in the PT. PLN (Persero) GIS 150 kV Gunungsari Rectifier room, Surabaya, which contained a DCDB panel. The data obtained is temperature monitoring data in the Rectifier room, DCDB panel body, and DCDB panel door. From this data, observations are made to see the temperature changes that occur in the panel. Environmental weather data is obtained via the Weather Underground website. The research data obtained was analyzed using RMSE and MAPE to check errors and graph plotting using SPSS. Based on the research conducted, it can be concluded that the dew point is estimated to occur at 03.30-05.00 in July with a temperature range of 21.3℃-23.3℃.

Abstract

The increasing amount of waste in Indonesia, especially in Surabaya, is a severe problem that must be resolved immediately. The amount of plastic waste in the city of Surabaya is one of the causes of damage to the environment. So that the plastic waste must be processed so that it can be reduced. Surabaya State University KKN students made this problem the basis for implementing the Socialization and Training of Plastic Waste Processing Types of LDPE (Low-Density Polypropylene) into Paving Blocks. The purpose of this activity is as an effort to reduce the amount of plastic waste and provide alternative new jobs for the community. This activity applies the lecture method, question and answer, simulation and practice. The action begins with the opening and filling out of the pre-test, then continues with filling in the material, making simulations, and the activity ends with closing and filling in the post-test. The pre-test and post-test assessments results showed that the participant's knowledge of the material was still classified as "low" with an average pre-test score of 52.40% and an increase in knowledge of the material as indicated by the post-test average score of 87 .27%. The activity concludes that participants experience an increase in knowledge and understanding of handling plastic waste into paving blocks and have knowledge about tools, materials, and processing methods to be applied in everyday life.

Abstract

Oxygen is a very important gas for humans. The need for oxygen around the plant is very low because the exhaust gas from various factories often becomes pollutants, one of which is the cement industry. The oxygen content needs to be known so that the level of vigilance of workers and the community is higher. For this reason, it is necessary to make a monitoring device for oxygen content. In this view will be discussed several gas sensors, especially oxygen sensors. In addition, Arduino microcontrollers and Raspberry Pi microprocessors were also discussed. The goal is to be able to determine the type of oxygen sensor as a detector of oxygen levels in the air. The discussion of microcontrollers and microprocessors is also a determinant of the motherboard connected to the oxygen sensor. Thus, the explanation of this review can be used to develop a monitoring system for oxygen content in the air.  The research method used is in the form of literature studies. Literature study is the process of finding research data or information by reading scientific journals, reference books, and articles about oxygen content monitoring devices. This tool functions as a gas analyzer by choosing the MQ-135 sensor as an oxygen sensor because it is more affordable and easy to obtain which is supported by the Raspberry Pi device.
