ABSTRAK Ponsel merupakan alat komunikasi yang banyak dimiliki oleh manusia. Hal ini dikarenakan keefektifan oleh ponsel itu sendiri. Dalam satu ponsel, penggunanya tidak hanya dapat berkomunikasi akan tetapi juga bisa melakukan berbagai aktivitas seperti mencari suatu informasi ataupun mendengarkan musik. Di balik kehebatan ponsel tersebut sebenarnya mengandung efek negatif berupa pancaran gelombang elektromagnetiknya yang berbahaya bagi otak, terlebih bila digunakan untuk menelepon dalam jangka waktu yang lama. Radiasi elektromagnetik yang berupa non-ionisasi ini baru akan menimbulkan efek negatif bila tubuh terpajan Specific Absorption Rate (SAR) >4 watt/kg. Saat menelepon efek yang langsung ditimbulkan berupa nyeri kepala karena adanya peningkatan tekanan darah, namun untuk waktu yang lebih lama lagi dapat menimbulkan kanker otak karena adanya penurunan produksi serotonin dan melatonin yang mana kerjanya untuk menekan timbulnya tumor. Mungkin Radiasi tidak berperan secara langsung dalam terbentuknya tumor, namun dalam studi lebih lanjut, paparan radiasi yang banyak juga dapat menaikkan malondialdehyde (MDA) serta pengurangan yang signifikan pada antioksidan seperti glutathione (GSH), superoxide dismutase (SOD), dan glutathione peroxidase (GPX). Hal ini dapat mengakibatkan peningkatan Reactive Oxygen Species (ROS) dan penurunan melatonin dalam serum sehingga terjadinya kerusakan oksidatif pada jaringan otak. Pada bagian hipokampus sendiri, didapatkan bahwa radiasi elektromagnetik dapat menghambat frekuensi pelepasan neuron pada Cornu Ammonis area 1 (CA1) hipokampus yang nantinya dapat menyebabkan penurunan kemampuan belajar dan memori.   Kata Kunci:  otak, paparan  gelombang elektromagnetik, ponsel  ABSTRACT Cell phones are a communication tool that is widely owned by humans. This is because of the effectiveness of the cellphone itself. In one cellphone, users can not only communicate but also can do various activities such as searching for information or listening to music. Behind this cellphone, it actually contains a negative effect consisting of the emission of electromagnetic waves which are harmful to the brain, before being used to move for a long time. Electromagnetic radiation which consists of non-recent ionization will have a negative effect if the body is exposed to Specific Absorption Rate (SAR)> 4 watts / kg. When calling the effects directly caused by blood pressure, but for a longer time can cause brain cancer due to a decrease in the production of serotonin and melatonin which is Tinjauan Pustaka  JIMKI Volume 8 No.1 | November 2019 – Februari 2020           90 needed to increase the incidence of tumors. Radiation may not directly support tumor formation, but in further studies, greater radiation exposure can also increase malondialdehyde (MDA) and also present significant antioxidants such as glutathione (GSH), superoxide dismutase (SOD), and glutathione peroxidase (GPX). This can increase Reactive Oxygen Species (ROS) and decrease melatonin in the serum thereby preventing oxidative damage to brain tissue. In the hippocampus itself, electromagnetic radiation can be obtained which can release the frequency of the release of neurons in the Cornu Ammonis area 1 (CA1) hippocampus that can be used can cause a decrease in learning ability and memory.      Keywords:  brain, cellphone, electromagnetic waves' exposure

Exposure to cellphone electromagnetic radiation can cause oxidative stress which can later lead to changes in the hippocampal pyramidal cells. This change can be characterized by a reduction in the number of pyramidal cells and a change in cell morphology characterized by occurrence of picnosis or hydropic degeneration in the hippocampal pyramidal cell nucleus. Alpha Spin can inhibit cell phone electromagnetic radiation exposure through the quantum energy field formed by Alpha Spin. This study aims to determine the protective effect of the use of Alpha spin antiradiation on the histology of the hippocampus of white rats (Rattus norvegicus) Sprague dawley strains exposed to mobile electromagnetic waves. Laboratory experimental research using randomized controlled methods with a post test only control group design. Samples were 30 white rats divided into 3 groups. The control group (K) was only given food and drink, the treatment group 1 (P1) was exposed to cellphone electromagnetic waves and the treatment group 2 (P2) was exposed to cellphone electromagnetic waves and placed Alpha Spin. Exposure is done 2 hours / day for 30 days. There were mean differences in all groups with a significant value, which was p <0.05. There is a protective effect of Alpha Spin antiradiation on the histology of the hippocampus white rat (Rattus norvegicus) Sprague dawley strain that is exposed to cellphone electromagnetic waves.
