Abstract

This study aims to provide an overview of easy multiplication with the left to right method and also the right to left method (Al Khawarizmi Method). Furthermore, from easy multiplication with 2 methods, a test is carried out to determine the level of ease in its application to the two methods of multiplication. The method used in this research is experimental. While the approach in this research used is quantitative. The quantitative approach used includes testing the hypothesis on the median value. The conclusion of this study is that the median value of the posttest value of easy multiplication from left to right and easy multiplication from right to left is the same. Since the median is also the average value, it can also be concluded that the average number of easy multiplication posttest scores from left to right and easy multiplication posttest scores from right to left are the same. As an implication, the two easy multiplication techniques are able to produce the same level of convenience.

Abstract

The purpose of this study discusses the concept of dual-use technologies (spin on and spin off) in an effort to accelerate the economic independence of the Indonesian defense industry. This research is a qualitative research, the type of research uses a comprehensive analytical study and analytical normative approach. The development of defense technology in addition to aiming at production independence that can compete with other countries' products, must also provide a multiplier effect. The strategy is clear: optimize the added value of the defense industry. To that end, the first step that must be taken is to encourage import substitution for the defense industry and, after the industry develops, the final step is to commercialize or spin off the spillover effect or defense industry multiplier effect in the form of products that can be used for civil benefit. Defense provides a direct advantage of technology and its influence on other sectors, where the spin-off is used by the civil sector which can increase growth. In developing countries, defense spending can increase growth if some portion of expenditure is used for the provision of social infrastructure. Defense spending provides protection for citizens, where internal and external security will increase exchange in the market.

Abstract

Tujuan penelitian ini membahas mengenai reaksi fisi dan fusi pada bom atom dan senjata termonuklir. Penelitian ini adalah penelitian kualitatif, jenis penelitiannya menggunakan studi analitik komprehensif. Bagian paling vital dari ledakan fisi yang terjadi dalam bom atom tak lain adalah material yang berfisi itu sendiri. Ada dua unsur radioaktif yang biasa dipakai, yakni uranium dan plutonium, masing-masing dengan aneka isotopnya. Mulai dari U-232, U-234, U-235, dan U-238 untuk uranium, hingga Pu-238, Pu-239, dan Pu240 untuk plutonium. Elemen pemicu ledak yang dipakai dalam ledakan termonuklir ialah deuterium (D) alias hydrogen berat atau yang juga popular dengan sebutan ‘air berat’ (heavy water). Dari setiap 5000 atom hydrogen, bisa dipastikan satu isotop di antaranya dalam bentuk deuterium. Inti deuterium (deutron) terdiri dari satu proton (p) dan satu neutron (n). saat berpasangan, dua deutron membentuk inti atom helium (He-4) yang relatif stabil. Dalam semua jenis reaksi ini, inti atom berat terbentuk melalui proses fusi. Kata Kunci: bom atom, reaksi fisi, reaksi fusi, senjata termonuklir The purpose of this research is to discuss fission and fusion reactions in atomic bombs and thermonuclear weapons. This research is a qualitative research. This type of research uses a comprehensive analytical study. The most vital part of the fission explosion that occurs in an atomic bomb is none other than the fission material itself. There are two radioactive elements in common use, uranium and plutonium, each with its different isotopes. They range from U-232, U-234, U-235, and U-238 for uranium, to Pu-238, Pu-239, and Pu240 for plutonium. The explosive trigger element used in thermonuclear explosions is deuterium (D) heavy hydrogen or also popularly known as "heavy water" (heavy water). For every 5000 hydrogen atoms, one can be sure of one of them in the form of deuterium. The nucleus of heuterium (deutron) consists of one proton (p) and one neutron (n). When paired, the two deutrons form a relatively stable nucleus of helium (He-4). In all of these types of reactions, heavy atomic nuclei are formed by fusion. Keywords: atomic bombs, fission reactions, fusion reactions, thermonuclear weapons

Abstract

Since a long time ago, BRS (Hospital Assistance) had played a major role in saving lives. Under the Hague Regulations of 1907, BRS type ships were prohibited from being attacked in warfare and these ships themselves were prohibited from possessing weapons. Indeed, World War I and II experience shows that BRS ships remain the target of attacks. It was only after World War II was over, this immunity could be implemented in the field. The Republic of Indonesia is a participant of the Geneva Conventions of 1949 concerning Protection of War Victims by means of a declaration of participation dated 10 September 1958, based on Law Number 59 of 1958 concerning the participation of the Republic of Indonesia in all Geneva Conventions on 12 August 1949 (Lembaran Negara No. 109, 1958. BRS operates not only during wartime, but also during peacetime, BRS operations in peacetime in the form of disaster relief and ordinary situations. In ordinary situations, BRS visits remote islands to provide medical assistance and equipment free medical services for the local community

Abstract

Tujuan penelitian ini membahas mengenai deskripsi pokok-pokok pikiran mengenai pembangunan kemandirian industri pertahanan Indonesia. Penelitian ini merupakan penelitian hukum normatif, tipe penelitiannya menggunakan kajian komprehensif analitis dan pendekatannya normatif analitis. Undang-undang industri pertahanan mengatur bahwa industri pertahanan terdiri atas industri alat utama, industri komponen utama dan penunjang, industri komponen dan pendukung (perbekalan), serta industri bahan baku. Dari awal, pemerintah sudah mengatur bahwa BUMN pertahanan menjadi industri alat utama sekaligus pemandu utama (lead integrator) yang menghasilkan alat utama sistem senjata dan/atau mengintegrasikan semua komponen utama, komponen, dan bahan baku menjadi alat utama. Pertahanan Indonesia memerlukan kebijakan yang lebih progresif untuk mengejar ketertinggalan dalam penguasaan ilmu pengetahuan dan teknologi (iptek) bidang pertahanan, serta dalam rangka mewujudkan kemandirian Industri Pertahanan (Indhan). Kemandirian industri pertahanan sangat bergantung pada tiga pilar pelaku iptek, yaitu perguruan tinggi dan Lembaga Litbang, industri, dan user (TNI sebagai pengguna). Oleh sebab itu, pemerintah  merumuskan kebijakan terpadu bidang iptek dan industri pertahanan yang diarahkan pada kebutuhan industri pertahanan. Pokok-pokok pikiran mengenai pembangunan kemandirian industri pertahanan Indonesia  meliputi: pembentukan dan penguatan KKIP (Komite Kebijakan Industri Pertahanan), pembinaan industri utama dan pendukung, pendanaan industri pertahanan, mandiri dalam membuat/memproduksi, peningkatan kemampuan dan penguasaan teknologi industri pertahanan lewat sistem nasional, Research and development (R & D), kekuatan pertahanan minimum / Minimum Essential Force (MEF) dan Industri Pertahanan.

Abstract

This study intends to provide a description of how the use of polonium-210 (210Po) as a poison in terms of toxicology. This research is a qualitative research, the type of research uses comprehensive analytic studies and analytical normative approaches. Polonium-210 is created in nuclear reactors. This element is very radioactive which if swallowed even a little is very fatal. After entering the blood tissue, the element mainly targets the liver and kidneys and bone marrow. After 210Po is absorbed into the body, the whole body is basically targeted. The dose given and the sensitivity of individual tissues determine the level of damage throughout the body. Unlike most heavy metals, 210 Po accumulates in soft tissue rather than bone. Polonium (210Po) is a producer of very active alpha particles, but only becomes toxic when entering the body. If entered into the human body, toxic effects are often fatal, even at very small doses. Most of the initial dose is quickly excreted in the feces and urine, but the rest is distributed to the soft tissues of the body.
