Abstract

The use of radiation on plants has varying effects depending on the type of radiation and dose given. This research aims to provide insight into the potential and effects of using radiation in plant breeding and its impact on the physiological and morphological characteristics of plants. This study examines various previous research on the application of radiation rays to horticultural plants, food plants and ornamental plants. The radiation used includes gamma rays, X-rays, sunlight and corona glow discharge plasma. The research results show that radiation can increase genetic diversity and influence plant growth characteristics such as plant height, number of leaves, and chlorophyll content. The right dose of radiation can produce superior varieties with desired characteristics. However, doses that are too high can reduce the survival rate and regeneration capacity of plants.

Abstract

The quality of biomass briquettes is largely determined by the type of raw material and the manufacturing process, especially in efforts to develop waste-based alternative fuels. This research analyzes the effect of the combination of coconut shells with cassava skins and corn husks on the physical properties and burning rate of briquettes using tapioca flour adhesive. Test results show that variations in biomass produce significantly different combustion characteristics. Cassava husk–coconut shell based briquettes showed a higher combustion rate (0.24 g/minute), while corn husk–coconut shell briquettes produced more stable combustion with a lower rate (0.17 g/minute). Even though the water content of the two briquettes is still within acceptable limits, the high ash content (>25%) is the main limiting factor because it does not meet the SNI 01-6235-2000 standard and has the potential to reduce energy efficiency. These findings confirm that the selection of biomass type and control of the carbonization process play a crucial role in determining the performance of briquettes. Optimizing production parameters is needed so that agricultural waste-based biomass briquettes can be developed as an alternative fuel that meets national quality standards and supports a sustainable energy transition.

Abstract

Disaster is an event or a series of events that threatens and disrupts people's lives and livelihoods, caused by natural and/or non-natural factors and human factors, resulting in human casualties, environmental damage, property losses, and psychological impacts. Hydrometeorological disasters are events related to water, atmosphere, and oceans. It is recorded that hydrometeorological disasters occurring in Indonesia reach 86%, including floods, tornadoes, landslides, forest and land fires, and droughts. Specifically, in Central Kalimantan Province, forest and land fires and floods are frequent disasters. Both fall into the category of hydrometeorological disasters, closely related to the climate in Central Kalimantan. In this study, the prediction of rainfall, temperature, and humidity values in Central Kalimantan Province was calculated using the Auto-Regressive Integrated Moving Average method at 5 stations in the province. Subsequently, the prediction analysis of flood events was carried out using the machine learning random forest method based on the rainfall data, temperature, humidity, and event data. According to the calculation results, flood disasters are not predicted to affect almost all areas of Central Kalimantan Province. However, by the end of 2023, it is anticipated that most areas in the province will still be categorized as experiencing a normal level of drought. Notably, there are two areas that must increase awareness of this drought disaster, namely Pulang Pisau and Sampit, especially in October 2023.

Abstract

Pengabdian kepada masyarakat merupakan bagian dari Tri Dharma Perguruan tinggi yang diarahkan pada upaya pembinaan IPTEKS dalam rangka meningkatkan kualitas sumber daya manusia melalui peningkatan mutu pendidikan. Tujuan pengabdian kepada masyarakat ini adalah untuk mengetahui penggunaan metode demonstrasi sains terhadap minat belajar siswa. Berdasarkan hasil wawancara dengan guru mata pelajaran di SMP Nathania Palangka Raya ditemukan bahwa minat belajar siswa terhadap sains tergolong rendah. Rendahnya minat belajar siswa diakibatkan oleh beberapa faktor salah satunya metode pembelajaran yang digunakan oleh guru. Metode pembelajaran yang digunakan oleh guru pada pembelajaran IPA/sains yakni metode ceramah. Guru masih belum menggunakan metode yang inovatif dan belum memanfaatkan media pembelajaran dalam proses pembelajaran sains. Hal ini perlu metode yang inovatif dan melibatkan media pembelajaran yakni metode demonstrasi. Khalayak sasaran pengabdian ini yakni seluruh siswa SMP Nathania Palangka Raya. Penggunaan metode demonstrasi pada pengabdian ini melibatkan alat peraga dalam menyampaikan materi pada pembelajaran sains. Siswa antusias dan aktif dalam proses pembelajaran. Hal ini membuktikan bahwa penggunaan metode demonstrasi pada pembelajaran sains dapat meningkatkan minat belajar siswa.
