Abstract

Fruits are included in foodstuffs that provide many benefits for the body, but fruits have a relatively short shelf life. ELF (Extremely Low Frequency) magnetic field radiation is radiation with a low frequency of around 0–300 Hz with non-ionizing properties or no effect on the atoms of a material it is subjected to and non-thermal or does not cause an increase in temperature when interacting with a material. In addition, Extremely Low Frequency (ELF) magnetic field radiation can be used for food tenacity. This study aims to determine how much influence ELF radiation has on the shelf life of various types of fruits. The method used in this study is the journal review method, the number of journals reviewed is 11 journals. The journal in question can be in the form of scientific articles and other journals that support and are relevant to the research title. The results of this study indicate that exposure to the ELF magnetic field can maintain the content of vitamin C, maintain the physical condition of the fruits, and increase the shelf life of fruits by maintaining pH by slowing down or increasing the pH, this is done by killing acid-forming microorganisms, In addition, exposure to the ELF magnetic field can reduce the respiration rate and the rate of ethylene production in fruits, this has an impact on extending the shelf life of fruits. The intensity and duration of exposure to the ELF magnetic field must be adjusted to the type and character of the fruit itself. Thus, it can be concluded that exposure to Extremely Low Frequency (ELF) magnetic fields are able to maintain vitamin C content, maintain the physical condition of fruits, and increase the shelf life of fruits.

Abstract

Indonesia is a tropical country that has quite a lot of sunlight, so that it is very close to sunlight that cannot be used properly. Sunlight can be used as solar panels. Solar panels are a tool that is able to convert sunlight into electrical energy, solar panels themselves can take advantage of various fields of agriculture, one of which is agriculture. The use of energy derived from solar panels can increase agricultural yields. In tropical areas such as Indonesia, which has two rainy and dry seasons, it has abundant sunlight. This study aims to determine what potential can be produced by solar panels to support energy in agriculture. The research method used in this article is the journal review method by conducting literacy of national and international articles, with the number of journals reviewed as many as 25 journals, the journals analyzed and reviewed are journals that have the subject matter according to the research title, the results of the research will be explained in descriptive form and presented in tabular form. The results obtained after reviewing several articles that contain several uses of solar panels in agriculture that can be used for spraying, fertilizing, lighting, drying, irrigation, setting PH and temperature. The use of solar panels has many benefits for farmers because it has several advantages, namely it can save operational costs, is environmentally friendly, efficient, and can be used in the long term.

Abstract

The problems that are often encountered are the problem of garbage or waste from human activities, these activities include households, agriculture, factories, and others. The purpose of this research is to reduce waste or waste that is really needed at this time whether it is used for other alternative sources that are environmentally friendly, so that waste or waste from agricultural activities does not continue to increase, organic fertilizer and briquettes or charcoal can be used. In this study using the method of literature review from various international journals. The journal used starts from the past 10 years, namely 2012-2022 and searches for it via Google Scolar. Keywords used when searching journals on Google Scolar such as "agricultural waste processing", "briquette management", and "agricultural waste". Garbage is the remains of human activities that are not reused but can produce a useful new product. There are various types of waste or waste, one of which is agricultural waste which can produce products that are beneficial to the environment or environmentally friendly. Agricultural waste is the part of agricultural plants from the top or shoots to the remaining stems after harvesting activities. Utilization of agricultural waste is very useful for humans, the environment, and other living things. One of the uses of this agricultural waste is as briquettes which are a new alternative source that is environmentally friendly because it comes from various plant residues produced during harvesting activities. Most of the agricultural waste comes from rice. So, the existence of agricultural waste can be used as a new alternative source that is environmentally friendly and inexpensive.

Abstract

Abstrak: Pembelajaran fisika merupakan fenomena alam yang dapat ditemui dan dapat dipelajari di kehidupan sehari-hari. Aliran air Bendungan Sampean Baru dapat dijadikan contoh penerapan fluida dinamis karena dapat ditemui di lingkungan sekitar siswa. Penelitian ini bertujuan untuk mengkaji aliran air bendungan sampean baru sebagai dasar untuk pembuatan LKPD. Penelitian ini menggunakan metode kualitatif deskriptif. Pengukuran yang dilakukan adalah pengukuran lebar aliran sungai, kedalaman sungai, dan pengukuran menggunakan metode apung (floating method), dilanjutkan dengan perhitungan matematis untuk mendapatkan luas penampang, kecepatan aliran, dan debit aliran. Hasil kajian fluida menunjukkan bahwa lebar aliran sungai berbanding terbalik dengan luas penampang aliran dan sesuai dengan hukum persamaan kontinuitas. Dari hasil analisis bahan pembelajaran fisika materi fluida berbasis kontekstual menggunakan kajian aliran air dapat meningkatkan pemahaman siswa dalam pembelajaran fisika pada materi persamaan kontinuitas Abstract: Physics learning is a natural phenomena that can be found and learned in everyday life. The water flow of Sampean Baru Dam can be used as an example of the application of dynamic fluids because it can be found in the environment around the students. This study aims to examine the water flow from the Bendungan Sampean Baru as a basis for making LKPD. This research uses a descriptive qualitative method. The measurements taken were the measurement of the width of the river flow, the depth of the river, and measurements using the floating method, followed by mathematical calculations to obtain the cross-sectional area, flow velocity, and flow discharge. The results of the fluid study show that the width of the river flow is inversely proportional to the cross-sectional area of the flow and is in accordance with the law of continuity equations. From the results of the analysis, contextual-based fluid physics learning using water flow, can improve students' understanding of physics learning on the continuity equation material.

Abstract

Loss of Aircraft Control incidents have occurred frequently in the past few years. In the last 7 years, 5 aircraft have experienced Loss of Aircraft Control. Loss of Aircraft Control itself is the disappearance of the aircraft from the monitoring radar. The causes of loss of aircraft contact include the effects of weather. In the aviation system, weather does have a very big influence. To minimize the loss of aircraft contact, each aircraft is equipped with a weather radar or what is known as the WX Radar System. WX Radar System is an example of the application of electromagnetic waves, namely radio waves that work with the principle of the doppler effect. Where the radar will emit electromagnetic waves with a low frequency which will then be reflected back by weather particles in the earth's atmosphere. The results of the reflection are then displayed in the cockpit of the aircraft so that the pilot knows the weather conditions outside the aircraft so as to avoid things that are not desired such as loss of aircraft contact or Loss of Aircraft Control.
