Abstract

Salah satu tantangan utama dalam pembelajaran fisika adalah keberadaan miskonsepsi yang menghambat pemahaman peserta didik terhadap konsep-konsep, khusunya dalam materi termodinamika. Penelitian ini bertujuan untuk mengembangkan perangkat pembelajaran berbasis model OPTHREE. Model ini merupakan perpaduan anatara pendekatan kontruktivis Predict-Observe-Explain (POE) dan Think-Talk-Write (TTW). Pengembangan perangkat ini difokuskan untuk membantu mengurangi miskonsepsi yang dialami peserta didik. Proses pengembangan mengikuti ilmu tahapan dalam model ADDIE, yaitu analisis, perancangan, pengembangan, penerapan, dan evaluasi. Fokus artikel ini terletak pada proses validasi perangkat pembelajaran yang meliputi modul ajar, bahan ajar, LKPD, serta instrumen evaluasi. Validasi dilakukan oleh dua pakar yang menilai aspek isi, kontruksi, kebahasaan, dan keterbacaan. Hasil validasi menunjukkan bahwa seluruh komponen perangkat pembelajaran termasuk dalam kategori “Sangat Valid”.  Dengan skor antara 3,75 hingga 4,00 dari skala maksimal 4,00. Uji coba terhadap perangkat pembelajaran dilaksanakan di SMA Negeri 1 Gorontalo. Hasil pelaksanaan tersebut menunjukkan bahwa perangkat yang dikembangkan dengan pendekatan model OPTHREE dapat berfungsi secara optimal dalam kegiatan pembelajaran. Selain itu, perangkat ini juga memberikan indikasi positif terhadap penurunan tingkat miskonsepsi siswa mengenai konsep-konsep dalam materi termodinamika.

Abstract

Penelitian mengenai pola arus di Teluk Palu sangat jarang dilakukan, padahal perairan ini merupakan daerah potensi strategis secara ekonomi. Studi mengenai pola arus Teluk Palu dilakukan dengan memanfaatkan model Coherens menggunakan Bahasa pemrograman fortran dengan mengabaikan gaya pembangkit angin sebagai pembangkit arus. Hasil penelitian menunjukkan bahwa arus pada Teluk Palu bervariasi baik arah maupun kecepatannya. Besar kecepatan arusnya berkisar antara 0,01 m/s hingga 0,33 m/s. Kondisi ini sangat dipengaruhi oleh pergerakan pasang surut baik saat purnama maupun perbani. Model pola arus laut permukaan di Teluk Palu ini diharapkan dapat bermanfaat bagi pembangunan dan pengembangan sekitar area teluk, bagi masyarakat dan juga bermanfaat bagi penelitian-penelitian selanjutnya

Abstract

Disaster is an event or series of events caused by natural factors or non-natural factors and human factors that threaten and disrupt people's lives and livelihoods, causing human casualties, environmental damage, loss of property and psychological impacts. The aim of the Village Project MBKM program is to carry out a disaster mitigation program. For this disaster mitigation program, students work directly with all Ulantha village communities and village officials as well as the Regional Disaster Management Agency (BPBD) in making evacuation routes and boundaries for flood-prone areas. This study uses a type of descriptive research. As a result of this Disaster Mitigation Program, MBKM Physics Education students for VILLAGE PROJECT collaborated with the Regional Disaster Management Agency (BPBD) so that the evacuation routes are safe and easy for the community to find when there is a major flood. Through the socialization of Disaster Mitigation is an education to the community, so that the community knows the right solution related to the problem of flooding and becomes an amplifier of the dangers from the impact of flooding.

Abstract

Modeling a tsunami measuring 8.5 SR using ComMIT software. The simulation results include data on wave arrival time, wave depth and maximum height at three coastal locations in North Gorontalo, namely Tomilito, Kwandang and Ponelo Islands Districts. In tsunami modeling in Kwandang Bay, there are differences in wave heights on three beaches in the North Gorontalo region, including Tomilito, Ponelo and Kwandang. On the coast of Tomilito District, the maximum tsunami height reached 11 meters. Meanwhile, on the coast of Kwandang District, the tsunami height reached 10 meters, and the lowest tsunami height occurred on the Ponelo coast with a height of 9 meters

Abstract

This study analyzes the seismic vulnerability index to slope stability in landslide-prone areas, Tomilito District, North Gorontalo Regency. The results of the study indicate that the seismic vulnerability index in this area is in the low category, which is at a vulnerable level (0.2246-1.047736) where if vibrations occur, the surface soil layer level does not experience deformation or changes in the soil so that it is safe from the influence of shaking reinforcement.

Abstract

Noise problems caused by crowded urban markets make it difficult for people to find a quiet location. Andalas has many settlements, especially in the market area, which is located in urban areas and on the edge of the highway, which is also close to the market. This study aimed to determine the effect of market noise on health. The noise levels were measured using a sound meter measuring instrument, which was measured in three places: a clothing store, a fish store, and a public parking lot. Hypothesis testing was done using the chi-square statistical test with a 95% confidence level (p = 0.05).

Abstract

A resistivity geoelectric research has been carried out to identify the suspected seepage of garbage pollutants around the Tanjung Belit village garbage dump. The study was conducted in 2 tracks. On track 1 with a track length of 100 m and 35 measurement points, the resistivity is in the range of 0.795-50.1 Ωm. On the 2nd track, 75 m long and 32 measuring points. The method used is the geoelectric resistivity method of the Wenner configuration with data processing using the res2dinv application which has a large resistivity ranging from 1.22-44.9 Ωm. Based on this resistivity, it can be seen that there is waste pollutant seepage located at a depth of 0.825–7.41 m. Keywords:Wenner, geolistric method, RES2DINV

Abstract

The increasing plastic waste volume in Gorontalo City is not balanced by a good management system, making people choose to burn their waste in open space. Not only makes a bad scene, this burning emits dangerous gases such as CO2 that contributes to poor air quality and climate change. This study has developed an environmentally friendly incinerator with a stacked condenser system that emits less CO2 gas. This incinerator consists of three main components: a combustion zone, as the place where plastic waste is burned; a chimney, for the flowing of gas; and stacked condensors, for cooling and keeping the gas before emitting it out. We test the incinerator with and without condensors based on the CO2 emission from 20 minutes' burning of 1.5 kg of plastic waste. The results show that an incinerator with a stacked condensor system can significantly reduce CO2 gas emissions by 18.88% more than an incinerator without condensors. This implies that incinerator with stacked condensors can be an alternative way to reduce CO2 gas from open-space waste burning on a small scale.

Abstract

One important parameter that needs to be considered in water quality is the acidity level (pH) in the water. This study aims to design and determine real-time and accurate pH sensor based on internet of thing (IoT). This system design uses an ESP32 microcontroller and The PH-4502C pH Meter Module sensor. The ESP32 can be connected to the IoT-based Blynk platform, allowing pH data to be monitored in real time via a smartphone. Testing of the IoT-based pH sensor was conducted to evaluate the system's real-time operation under varying distances. Meanwhile, the pH sensor's accuracy was determined by comparing its output with a digital pH meter using buffer solutions at different pH levels. The test results show that the time value required in each range is always constant, namely 1 s. This proves that IoT-based monitoring does not affect the range. Meanwhile, measurement of pH level was the average error value is 3.49%, and the sensor accuracy is 96.51%. These results indicate a low error rate, resulting in high accuracy. The sensor error value of 3.49% is lower than the specified error tolerance limit of <5%. This proves that the pH sensor, with an accuracy of 96.51%, is suitable and reliable for measuring pH in solutions.
