Abstract

Humans are God's most perfect creatures compared to other creatures, because humans are given reason to think. However, not all humans have this level of intelligence or sensitivity in logical, critical, creative or innovative thinking. This is based on the development of human thought patterns that are not simultaneous. Human thought patterns are influenced by the surrounding circumstances and of course influenced by the human will itself. If you look back, in the Babylonian era, ancient humans (approximately 650 BC) only had the mindset of maintaining their survival by moving around (nomadic). This is because at that time human were still based on customs and still believed in myths. This is different from today where humans have developed more in terms of thought patterns. Human today tend to have a higher level of curiosity, especially with the current advances in science and technology. . Science and technology develop together with science, so that the two have a continuous relationship. So human thought patterns are greatly influenced by knowledge which is becoming increasingly widespread along with advances in science and technology

Abstract

Perairan di bumi menguasai sebesar 71% yang berarti seluas 361,1 juta kilometer persegi. Hal ini disebabkan karena sejak awal mula bumi terbentuk, planet ini diliputi oleh lautan. Bumi juga dikenal sebagai planet air. Indonesia menjadi negara dengan wilayah lautan terluas di dunia. Sehingga air laut di Indonesia dapat dimanfaatkan menjadi berbagai sumber energi,salah satunya energi listrik. Penelitian ini bertujuan untuk mengetahui seberapa berpotensi sumber energi air laut di Indonesia sebagai alternatif energi listrik.Penelitian ini dilakukan dengan menggunakan metode deskriptif kualitatif. Penelitian deskriptif kualitatif merupakan penelitian yang mendeskripsikan keadaan dan hasil yang diperoleh secara menyeluruh. Sedangkan untuk teknik pengumpulan data dengan menggunakan penelitian deskriptif kualitatif dengan metode literature review. Energi laut yang dihasilkan dari gerakan dan perbedaan suhu lapisan laut (samudera) merupakan sumber energi di perairan laut yang berupa energi pasang surut, energi gelombang, energi arus laut, dan energi perbedaan suhu lapisan laut. Ke empat sumber energi tersebut dapat dimanfaatkan sebagai alternatif energi listrik menggunakan bantuan teknologi modern. Pada penelitian ini akan berfokus pada energi gelombang air laut, dimana gelombang merupakan pergerakan naik dan turunnya air dengan arah tegak lurus permukaan air laut yang membentuk kurva/grafik sinusoidal. Gelombang laut disebabkan oleh angin. Angin di atas lautan mentransfer energinya ke perairan, menyebabkan riak-riak, alun/bukit, dan berubah menjadi apa yang kita sebut sebagai gelombang.

Abstract

The processing of rice and corn crops today relies heavily on the utilisation of physical principles in the use of modern machinery. Rotary dryers dry grain and corn kernels by relying on heat and mass transfer, mainly through convection and conduction processes. Factors such as air temperature, airflow speed, drum rotation, as well as the thermal properties of the material being dried, greatly affect the speed of water evaporation and the quality of the final product. Meanwhile, combine harvesters integrate various stages of work-from cutting, threshing, separating, to cleaning-by utilising the concepts of mechanical force, impulse, friction, and centrifugal force. The effectiveness and efficiency of this machine depends on the settings of drum speed, cutting angle, forces acting on the crop, and vibration frequency in the separation system. Understanding the fundamentals of physics in this technology is key to designing a more efficient and energy-efficient machine. With proper application of the principles, the productivity and quality of rice and maize crops can be improved, especially in facing the challenges of tropical climate in the main agricultural areas. An in-depth understanding of the principles of physics is instrumental in improving the efficiency and quality of rice and corn yields after harvest. Through the development of sustainable rotary dryer and combine harvester technologies, it is expected that the productivity of the agricultural sector can increase significantly, while minimising the negative impacts of erratic tropical climate conditions. With the application of this physics-based technology, the agricultural sector can achieve more optimal results, reduce post-harvest losses, and utilise resources more effectively and sustainably.
