Abstract

The problem in Maluku is about earthquake mitigation and the lack of our young generation or students who master Internet of Things (IoT) technology. The reason why this issue should be a major concern is because Maluku is an earthquake-prone area. Providing understanding about earthquakes and earthquake mitigation is carried out through outreach to schools so that it is hoped that teachers and students will become pioneers who can provide understanding or knowledge about earthquakes and earthquake mitigation for each family and in their respective environments. Apart from that, mastery of IoT technology is very important. This is because IoT is the basis for creating the industrial era 4.0. The lack of knowledge about IoT technology among students in Maluku is a concern in increasing students' knowledge about IoT technology. To overcome this problem, socialization and simulation activities were carried out in schools which were partners in the Community Service Program activities in providing IoT training and the application of IoT in the industrial world. It is hoped that mastering the basic knowledge of IoT technology can support innovative IoT-based learning processes. IoT-based learning provides stimulus for students to carry out various experiments that are more innovative, creative and independent. Earthquake mitigation socialization activities and IoT technology workshop activities will be carried out at MAN 1 School, Central Maluku.

Abstract

Household organic waste such as banana and pineapple peels are often not optimally utilized, even though they contain nutrients that are good for plants. This community service activity aims to provide counseling and training on making environmentally friendly liquid fertilizer by utilizing banana and pineapple peel waste using EM4 activator to the community in Kamal Village, West Seram Regency (SBB), Maluku Province. Through a participatory approach, this activity involves the community directly in the process of making liquid fertilizer, starting from the preparation of ingredients, fermentation, to application to plants through foliar spraying and direct watering to the planting media with a measured dose (50-100 ml of liquid fertilizer / 1 liter of water) every 7 days. This activity was carried out in 2 stages including the extension and training stages, as well as the monitoring and evaluation stages. The results of the activity showed an increase in participants' knowledge and skills in managing organic waste into useful and environmentally friendly products. With this activity, it is hoped that the community can apply this simple technology independently to support sustainable agriculture and reduce environmental pollution

Abstract

A landslide disaster is one of the natural disasters that has a detrimental impact on society. This impact can be avoided if the community knows the signs of landslides and gets a warning that a landslide will occur. Therefore, this study aims to design an laboratory landslide warning monitoring system based on Internet of Things (IoT) technology. Landslide monitoring using a tilt sensor connected to a web communication network. Before data testing, IoT sensor calibration was carried out. The calibration results showed a coefficient of determination (R2 = 0.9967), so that this sensor system can be used as a smart sensor in monitoring landslides. In the data acquisition process, the IoT system sends data in real time which is received by the computer via the internet network. The web communication network displays the results in the form of a 2D profile in real time, namely a graph of the slope angle against time. To confirm the web monitoring data, a computer programming language is used to display a 3D profile of the slip plane. The study results show that IoT technology can monitor landslides and the presence of artificial rain in real time with a reading of the soil displacement sensor of 32.4°. At this angle, a landslide occurs until it deposits under the foot of the slope, with a landslide mass deposition rate of 0.0012 m3/s. The designed IoT system is portable and permanent and can monitor landslides. This system can be developed more widely in areas prone to landslides for smart communities and can be used as a disaster prevention and mitigation movement in arranging spatial planning based on disaster mitigation. This research can advance our understanding of landslide monitoring dynamics using web-based IoT systems, providing important insights for mitigation strategies and future research.

Abstract

Climate change has triggered increased rainfall intensity and exacerbated the risk of disasters, especially landslides in the tropical hilly areas of Ambon Island. This community service activity was carried out in Karang Panjang Village, Sirimau District, Ambon City, to increase public awareness and knowledge about the impacts of climate change and preventive strategies for slope landslides. Activities include geoscience and bioengineering-based education and direct practice of planting vetiver grass (Chrysopogon zizanioides) as a natural solution for slope prevention. The evaluation results showed an increase in public understanding by 24.7% after participating in a series of socialization activities. In addition to gaining knowledge about the causes and dynamics of slope stability, residents were also equipped with skills to plant and maintain vetiver independently and sustainably. This program proves that an educational and participatory approach can be a strong foundation for community-based disaster mitigation.

Abstract

An Arduino Uno-based static friction coefficient (µs) determination tool equipped with an IR sensor module FC-51 has been created. This µs determination tool is made to reduce the possibility of observation errors when doing physics labs. The µs determination tool consists of an FC-51 IR sensor component to detect precisely when an object is moving. The potentiometer measures the angle of the base surface, and an Arduino Uno device transmits data from the hardware to the computer in real time. The work test of the µs determination tool starts with the base surface with a slope of 0o, and then the object is placed on the base surface and precisely above the surface of the FC-51 IR sensor. When the base surface is tilted slowly, the potentiometer also rotates, showing the plane angle's size. As long as the object is not moving, the IR FC-51 sensor is in low condition. When the object moves, the IR FC-51 sensor is in high condition. The change in signal from low to high indicates that the object is moving when the plane reaches the slope angle, and the slope angle shows the value of µs. The µs are measured on a wooden base with wooden blocks and a glass base with glass blocks. The results obtained for a wooden base with wooden blocks µs = 0.73 with an average slope angle = 36.16o and a glass base with glass blocks µs = 0.4 with an average slope angle = 22.1o. The results show that the µs level of the wood surface with wood is greater than the µs level of the glass surface with glass.

Abstract

An instrument for measuring I-V characteristics and determination of the dynamic resistance of a Silicon 1n4002 diode based on Arduino Mega 2560 has been successfully developed. This measurement was carried out by increasing the bias voltage periodically from 0 V to 5 V and observing the resulting forward voltage and forward current for each increase in the bias voltage. There is an increase in current when the diode voltage reaches 0.7 V, which is the diode barrier voltage. This happens if the limit resistor installed in the circuit is 100 Ω. The largest dynamic resistance value is 593.069 Ω, which is below the forward voltage of 0.6 V. Furthermore, the smallest dynamic resistance value is 2.293 Ω which is above the forward voltage of 0.7 V. The greater the value of the current flowing in the diode circuit, the smaller the dynamic resistance value of the diode and the smaller the value of the current flowing, the greater the dynamic resistance of the diode.

Abstract

Pembelajaran IPA mestinya lebih menekankan pada dimensi pedagogik modern, yaitu menggunakan scientific approach. Pembelajaran yang relevan diterapkan adalah pembelajaran melalui eksperimen (praktikum). Melalui praktikum siswa memahami fenomena alam yang dikaji dari berbagai sudut sehingga siswa dapat belajar lebih bermakna (meaningful learning). Namun, kendala yang sering dihadapi yaitu kegiatan praktikum memerlukan waktu yang lama jika pembelajarannya dikemas dalam praktikum. Oleh karena itu diperlukan adanya suatu kegiatan pemberdayaan untuk meningkatkan kompetensi guru dalam melaksanakan praktikum. Kegiatan pemberdayaan ini dikemas dalam bentuk inservice training yaitu pelatihan dan pendampingan penggunaan alat praktikum IPA secara terintegrasi pada siswa dan guru di SMA. Pelatihan yang dilaksanakan adalah pelatihan mengembangkan keterampilan dan kreativitas guru IPA dalam menggunakan perangkat praktikum IPA terintegrasi yang memanfaatkan KIT IPA yang sudah diproduksi. Pendampingan juga dilakukan terkait dengan meningkatkan kemampuan guru dalam mengeksplorasi, mengelaborasi dan merefleksi materi ajar IPA. Kegiatan pelatihan dan pendampingan kepada guru dan siswa ini akan dilakukan di SMA Negeri 2 Seram Bagian Barat.

Abstract

Water quality in cultivating marine organisms is a very important part to pay attention to. Prevention of pollution in marine waters needs to be done by recognizing changes in physical, chemical and biological parameters in these waters from normal conditions. To find out these changes, it is necessary to carry out measurements which include parameters that determine the quality of a liquid and carry them out periodically. The measurement parameters measured include pH, Dissolved Oxygen (DO), Electrical Conductivity (EC) and temperature. The use of technological developments, especially in the world of microcontrollers, namely the ESP32 device, makes it possible to design measurement instruments in determining the quality of sea waters to be more efficient and comprehensive. The instrument created in this research will be equipped with several sensors that will read the parameters that determine water quality. The sensors used are pH sensors, DO sensors, EC sensors and temperature sensors. This research aims to create an integrated instrument (pH, DO, ED and Temperature) with instrument performance specifications that have good accuracy and a portable design so that it is easy to use in the field. The research results show thatdevelopment of a biosensor instrument for measuring seawater quality based on the ESP32 DevKit V1 can work well and can display temperature, degree of acidity (pH), DO and EC parameters on the LCD screen according to actual conditions with a difference range in percent between 0.2% - 4.16 %. The accuracy level of the designed tool is classified as having a high accuracy above 95%
