Anticancer Diets

Anticancer Diets             You can reduce your chances of developing cancer and several chronic diseases by making healthy food choices . An anticancer diet is an important strategy to prevent cancer. The best way to reduce your risk of cancer is to consume anticancer foods, to eat more antioxidant foods, and to avoid carcinogenic foods.             There are various foods which has anticancer activities. Most of them can be found in plant foods, including fruits and vegetables. Fruits and vegetables are rich in cancer-fighting nutrients and non-nutrients (phytochemicals). Recent studies found, in several compounds show a very strong anticancer activity. It contains polyphenol compounds which have bioactivity potential to anticancer.             Another way to reduce the risk of cancer is to eat more antioxidant foods. Antioxidants are found in certain foods and may prevent some of the damage caused by free radicals by neutralizing them. The body can cope with some free r

Mineral vs Organic Sunscreen : Which is Better?

Mineral vs Chemical Sunscreen Sunscreen is important to protect your skin from any skin damage . UV light can damage your skin tissue and leads to skin cancer. Mineral and organic sunscreen are two different types of sunscreen based on its ingredients. It is important to understand the differences between mineral and chemical sunscreen.             Each type of sunscreen has a different way to protect your skin. The ingredients of mineral sunscreen (zinc oxide and titanium dioxide) are small particles that will sit on the skin’s surface. Mineral sunscreen ingredients reflect the UV rays away from the skin. On the other hand, chemical sunscreen ingredients (oxybenzone, avobenzone, etc.) penetrates the top layers of the skin to absorb the UV rays into the skin. Once the UV rays absorbed, the chemicals in the sunscreen create a chemical reaction in which UV rays are converted to heat.             Mineral sunscreen is more stable than chemical sunscreen because the ingredients h

The Reasons Why People Need To Eat Plant Foods

The Reasons Why People Need To Eat Plant Foods Bioactive compounds such as polyphenols, carotenoids, vitamins, phytoestrogens, glucosinolates, and anthocyanins present in fruits and vegetables. There are many reasons why people need to eat plant foods to promote their health. The source of antioxidants can be found in plants, such as grapes, apples, tomatoes, etc. Th e process of oxidation in the human body damages cell membranes and other structures, including cellular proteins, lipids, and DNA. When oxygen is metabolized, it creates unstable molecules called ‘free radicals’, which steal electrons from other molecules, causing damage to DNA and other cells. A diet high in antioxidants may reduce the risk of many diseases, including heart disease and certain cancers. The body's immune system is designed to fight off threats, like infection-causing germs, through a process called inflammation. But a steady state of inflammation can lead to everything from diabetes to au

Spectroscopy

Spectroscopy When we have an unknown compound, we need to identify it with spectroscopy. Spectroscopy  is a general term used for the instrumental processes by which information about the molecular structure is obtained through careful analysis of the  absorption ,  scattering , or emission of  electromagnetic radiation  by compounds. Structure identification of compound can be divided into three types of spectroscopy based on the principles, such as ultraviolet spectroscopy, infrared spectroscopy, and NMR spectroscopy. Identification of the unknown compounds can be analyzed by using ultraviolet Spectroscopy. The ultraviolet spectrum of the unknown compounds will absorb in the UV-Vis wavelength range (λ maks ) . The spectrum will absorb at a given wavelength and this property is due to functional groups, conjugation, etc. UV-Vis can be used in a qualitative manner, to identify functional groups or confirm the identity of a compound by matching the absorbance spectrum. It ca

Isolation Curcumin from Turmeric Plant

Isolation Curcumin from Turmeric Plant             Curcumin compound produced by Curcuma longa plant or we can call it turmeric. It has many scientifically-proven health benefits, such as the potential to prevent heart disease, Alzheimer’s, and cancer. It’s a potent anti-inflammatory and antioxidant and may also help improve symptoms of depression and arthritis. A compound inside a plant can be isolated by using a specific step and method.             The first step is extraction by using the maceration and partition method. The turmeric roots need to be dried and powdered before start the maceration method. After getting that dried and powdered turmeric roots, soak it in the methanol at the room temperature and leave it for one night. Then evaporate the methanol extract to obtain a crude methanol extract. The next method is partition twice with different eluents. First partition with n-hexane and the second partition with ethyl acetate. The target compound will be found in the

Gangguan Keamanan Dalam Negri

Gangguan Keamanan dalam Negeri   Dalam upaya menegakkan kemerdekaan bangsa Indonesia tidak hanya mengharapkan dari kekuatan asing yang meliputi Sekutu dan NICA, tetapi juga menghadapi berbagai ancaman dalam negeri tersebut. Beberapa gangguan keamanan dalam negeri antara lain sebagai berikut : o   Pemberontakan DI/TII Pemberontakan DI/TII pada mulanya terjadi di daerah Jawa Barat di bawah pimpinan Kartosuwiryo ia memproklamasikan berdirinya Negara Islam Indonesia pada tanggal 7 Agustus 1949. Gagasan Kartosuwiryo mendirikan Negara Islam muncul sejak tahun 1942, ketika mendirikan pesantren Sufah  di Malangbong, Garut, Jawa Barat. Setelah terjadi agresi Militer Belanda I tahun 1947, Kartosuwiryo menyatakan perang fisabililah melawan Belanda. Pasukan Hisbullah dan Sabilillah dijadikan Tentara Islam Indonesia (TII). Dalam konferensi di Cisayong bulan Februari 1948 diputuskan untuk mengubah gerakan yang dipimpin Kartosuwiryo diangkat sebagai imam dari Negara Islam Indonesia. Dengan
