Abstract

Plastic waste is an environmental problem that is very difficult to solve. To decompose it alone takes approximately 80 years for the plastic waste to decompose completely. In 2022, plastic waste will be the second most generated waste after food waste, which is 17.8% of all waste generated in Indonesia. Therefore, this research was made to overcome environmental problems due to plastic waste by utilizing thermal technology in the manufacture of Wood Plastic Composite (WPC). This research uses the literature study method by collecting several reading sources from previous research. In the utilization of thermal technology, several stages are carried out, namely washing, drying, chopping, then given thermal treatment, and the last is printing. the utilization of thermal technology in the processing of plastic waste into Wood Plastic Composite (WPC) is effective in reducing environmental pollution due to plastic waste. Processing plastic waste through thermal technology will increase the durability of Wood Plastic Composite (WPC) such as water resistance, color resistance to ultraviolet radiation, and this material is environmentally friendly. The utilization of thermal technology in converting plastic waste into Wood Plastic Composite (WPC) will help reduce the amount of plastic waste and reduce environmental pollution due to plastic waste.

Abstract

Indonesia has a lot of great potential that can help human resources in carrying out daily activities, especially in the maritime sector, which is very broad and large, measuring almost ± 6,000,000 km2. Unfortunately, the utilization of air wave energy has not been fully utilized optimally and several researchers have not carried out much research regarding the electrical energy formed from sea waves. The government has a policy to facilitate researchers' interest in conducting research so that there are many numerical specifications for the energy potential of ocean currents in turbine trials. There has been research into turbine trials at sea since 2006. Current turbines are an alternative energy source from kinetic energy to electrical energy. This research was carried out using a qualitative descriptive method, namely research that can describe the results that have been obtained by several studies that have been carried out previously. So far, the resources used by humans to generate electricity mostly use non-renewable resources such as fossil fuels (petroleum and coal).

Abstract

The collection of knowledge and techniques used to create tools, a system, and a method that helps us solve problems to achieve certain goals is called technology. Technology also covers various fields, such as information technology, biomedical technology, agricultural technology, and many more. Where each field uses its own knowledge and techniques to create solutions to problems in everyday life. Water is the most important component in life on earth, all living creatures need water to survive, including humans. Chemically, water consists of hydrogen atoms (H) bonded to oxygen atoms (O), so it has the chemical formula H20. However, currently the clean water crisis is occurring in almost all big cities in Indonesia. Due to water pollution due to human activities, such as industrial waste disposal, intensive agriculture, and the use of dangerous chemicals, water loses its best quality. Therefore, water treatment technology has a very important role to support people's needs for clean water.

Abstract

This study explores the integration of environmental ethics, cultural traditions, and technological innovation in disaster mitigation education to enhance the resilience of communities vulnerable to natural disasters, particularly those near Mount Semeru. Employing a qualitative methodology with a phenomenological approach, this research examines Javanese cultural perspectives on human-nature relationships and their implications for disaster preparedness. Data collection involved interview with village elders, community leaders and village youth, document analysis of Javanese philosophical texts, mythology, and oral traditions, as well as expert consultations with scholars in Javanese cosmology and disaster education. Thematic and comparative analyses were conducted to identify key patterns in disaster perception and response. The findings reveal that the Semeru community’s mitigation strategies are deeply rooted in traditional wisdom, classified into narrative, mystical, and functionalistic guidance, forming the basis of the ‘Triple N’ model: Nuturi, Niteni, and Nindaki. This framework emphasizes socialization, internalization, and enculturation to strengthen disaster awareness and community leadership. The study contributes to disaster education by bridging traditional knowledge with modern mitigation strategies, offering a culturally grounded approach that enhances community preparedness and response effectiveness. The Triple N model offers a culturally grounded framework that enhances disaster education, strengthens community resilience, and supports the development of a disaster mitigation curriculum.

Abstract

This article describes the results of a study on the measurement and analysis of magnetic fields in the area around a 150 kV High Voltage Overhead Line (SUTT). The main objective of this study is to assess the magnitude of the magnetic field generated by the SUTT and its potential impact on the environment. The approach used includes direct measurements using special equipment at a number of locations along the SUTT route. The results obtained show that the intensity of the magnetic field varies depending on the proximity of the measurement point to the SUTT, with the highest values ​​recorded at the closest location and decreasing significantly at further distances. The analyzed data show that the detected magnetic field is still within the acceptable threshold based on applicable standards. These findings provide an important picture of the impact of the presence of a 150 kV SUTT on the surrounding environment, and emphasize the importance of continuous monitoring to ensure that the magnetic field level remains safe. This study is expected to be a reference in the management and planning of electricity systems in the future.

Abstract

Pemantulan cahaya merupakan salah satu sifat dasar cahaya yang terjadi ketika berkas cahaya mengenai suatu permukaan dan dipantulkan kembali ke arah tertentu. Penelitian ini bertujuan untuk memahami hukum pemantulan cahaya serta menentukan hubungan antara sudut datang dan sudut pantul pada berbagai jenis permukaan reflektif, seperti cermin datar, cermin cekung, dan cermin cembung. Metode yang digunakan adalah pengamatan langsung menggunakan sinar laser dan papan optik untuk mengukur sudut datang serta sudut pantul. Hasil percobaan menunjukkan bahwa sudut datang sama dengan sudut pantul (i = r) pada semua jenis permukaan yang diamati, sesuai dengan hukum pemantulan cahaya. Selain itu, pada cermin cekung dan cembung terlihat bahwa arah dan fokus pantulan bergantung pada bentuk lengkung permukaan. Kesimpulannya, percobaan ini membuktikan bahwa hukum pemantulan cahaya berlaku universal dan karakteristik pantulan dipengaruhi oleh jenis cermin yang digunakan.

Abstract

Pemantulan cahaya merupakan salah satu sifat utama dari cahaya yang penting untuk dipahami karena memiliki banyak penerapan dalam kehidupan sehari-hari, seperti pada penggunaan cermin, periskop, serta berbagai perangkat optik modern. Praktikum ini bertujuan untuk membuktikan kebenaran hukum pemantulan cahaya dan mengkaji hubungan antara sudut datang dengan sudut pantul. Metode yang dilakukan ialah dengan menyorotkan berkas cahaya dari sumber laser ke permukaan cermin datar pada beberapa variasi sudut datang, kemudian mengukur sudut pantul menggunakan busur derajat. Berdasarkan hasil pengamatan, diperoleh bahwa nilai sudut pantul selalu sama atau mendekati sudut datang pada setiap percobaan. Temuan ini membuktikan kesesuaian dengan teori hukum pemantulan yang menyatakan bahwa sudut datang sama dengan sudut pantul, dan bahwa sinar datang, sinar pantul, serta garis normal berada pada bidang yang sama. Dengan demikian, hasil praktikum ini menegaskan bahwa hukum pemantulan cahaya berlaku secara konsisten pada cermin datar dan memperkuat pemahaman mahasiswa terhadap konsep dasar pemantulan cahaya.

Abstract

The water energy potential found in the Sengguruh and Wonorejo reservoirs serves as a source for Hydroelectric Power Plants (PLTA) located in the Brantas River Basin (DAS Brantas). The river flow has significant potential to be used as a source of electricity generation. The Brantas River possesses considerable potential for the development of Micro-Hydro Power Plants. The Weir and Flume method, which relates to threshold levels, average power, and water discharge, is used. Discharge is calculated based on the water level above the weir or within a narrow channel. At the Sengguruh PLTA, the inflow water discharge produced is 1.57 m³/s. Meanwhile, at the Wonorejo PLTA, the river inflow discharge calculated using the F.J. Mock method ranges from 0.94 m³/s to 16.99 m³/s, with a dependable discharge of 1.833 m³/s. It is therefore concluded that the electrical energy potential between the two reservoirs is greater at the Sengguruh PLTA
