Impact Analysis of Malware Based on Call Network API with Heuristic Detection Method

Malware is a program that has a negative influence on computer systems that don\u27t have user permissions. The purpose of making malware by hackers is to get profits in an illegal way. Therefore, we need a malware analysis. Malware analysis aims to determine the specifics of malware so that security can be built to protect computer devices. One method for analyzing malware is heuristic detection. Heuristic detection is an analytical method that allows finding new types of malware in a file or application. Many malwares are made to attack through the internet because of technological advancements. Based on these conditions, the malware analysis is carried out using the API call network with the heuristic detection method. This aims to identify the behavior of malware that attacks the network. The results of the analysis carried out are that most malware is spyware, which is lurking user activity and retrieving user data without the user\u27s knowledge. In addition, there is also malware that is adware, which displays advertisements through pop-up windows on computer devices that interfaces with user activity. So that with these results, it can also be identified actions that can be taken by the user to protect his computer device, such as by installing antivirus or antimalware, not downloading unauthorized applications and not accessing unsafe websites. &nbsp

Pemanasan Global Dan Keanekaragaman Hayati

Global warming will have a negative impact on biodiversity. In contrast,the increase of population in the world has an effect to the need ofbiological resources for food, industry, medicine, etc. Human activitiesin several sectors, such as energy, forestry, agriculture, husbandry,and waste create a greenhouse effect. Greenhouse effects are due to arise of greenhouse gases, such as CO2 (carbon dioxide), CH4 (methane),N2O (nitrogen dioxide), PFCS (perfluorocarbon), HFCS (hydrofluoro-carbon), SF6 (sulfurhexafluoride), and H 2O (water vapor). Studiessuggest that climate change may also cause the melting of polar ice-caps, rising sea levels, and a shift of season. Global climate changewiil also have a wide range of effects on human health, including a riskof infectious disease epidemics. Therefore, climate change is a seriouslythreat for the world and it is necessary to have a global agreement tocombat the threat. In 2005, Kyoto Protocol was agreed and The CleanDevelopment Mechanism (CDM) is a the Kyoto Protocol's mechanismaimed at helping industrialized countries meet their greenhouse gasreduction targets. The CDM is also meant to help developing countriesachieve sustainable development, including facilitating the transfer and/or development of low-emission technologies. Long term collectiveefforts are needed to combat and adapt with adverse effects of globalwarming, especially for the extinction of biological diversity

Eliminasi Logam Berat Kadmium Dalam Air Limbah Menggunakan Tanaman Air

Aquatic plants (Eichornia crassipes, Pistia stratiotes and Salvinia cucullata)were grown in a nutrient solution in the presence of Cd ion (0,2 mg/L). Analysiswere performed to established whether there was a removal of Cd in solutionand there was accumulation of Cd in the roots and shoots of the plants.Analysis of Cd concentrations in water was performed everyday and at the endof the experiment the shoot and root of the plants was harvested. The resultsshowed that Cd concentrations in all solutions declined until tenth day.Eichornia crassipes could remove Cd in solution completely by six days. WhilePistia stratiotes and Salvinia cucullata of Cd removal rate were 93,5 % and 77,4%, respectively. Root to shoot concentration ratio of Cd was 36 for Eichorniacrassipes and 10 for Pistia stratiotes

Sifat Fisik Daging Domba Yang Diberi Perlakuan Stimulasi Listrik Voltase Rendah Dan Injeksi Kalsium Klorida

Effect of low voltage electrical stimulation (LVES; 45 volt, 3 amps for approx 100 sec) and calcium chloride (CaCl2) injection on physical properties of meat were evaluated. Six mutton were devided into 3 groups. One carcass of each group was subjected to within 30 min postmortem (PM). After LVES, longissimi thoracis et lumbarum muscles were removed and treated: without CaCl2 injection, CaCl2 injection (200 mM, 5% w/w) at about 2 h and 24 h PM. Samples were stored in vacuum pack at 1 + 10 C. Physical properties evaluated were Warner-Bratzler (WB) shear force, cooking loss and sarcomere length. The LVES had no significant effect on WB shear force, cooking loss and sarcomere length. There wasn't interaction effect between LVES and CaCl2 injection on WB shear force, cooking loss and sarcomere length. CaCl2 injection decreased sarcomere length (

Effectiveness of the Red Dragon Fruit (Hylocereus Polyrhizus) Peel Extract as the Colorant, Antioxidant, and Antimicrobial on Beef Sausage

This study aimed to evaluate the effectiveness of red dragon fruit (Hylocereus polyrhizus) peel extracts addition on beef sausages. Red dragon fruit peel extracts were obtained by maceration using solvent at pH 5. Phytochemical characteristics, total phenols, antioxidant, and antimicrobial activity of the peel extracts were observed. Antioxidant and antimicrobial activities of the extracts were associated with high phytochemical compounds and total phenols contained in the extracts. Red dragon fruit peel extracts with various percentages (0%, 20%, 30%, and 40%) were added on beef sausages, and their physicochemical characteristics, nutrients, antioxidant activity, and microbiological profile were analyzed. The data were analyzed using analysis of variance and Duncan\u27s multiple range test. Results showed that the addition of red dragon fruit peel extracts significantly reduced texture values, but increased intensity of luminosity, intensity of red color, and intensity of yellow color (P<0.05) beef sausages. It could be concluded that red dragon fruit peel extract containing phytochemical compounds was effective as an antibacterial agent and natural antioxidant. The addition of red dragon fruit peel extracts was effective in increasing the antioxidant activity and decreasing TBARS values. The addition of red dragon fruit peel extract did not affect the reddish colorization of beef sausages, but it was capable of increasing the yellowish colorization on beef sausage

Fitoremediasi Tanah Tercemar Minyak Bumi Menggunakan Empat Jenis Rumput

Penelitian fitoremediasi tanah tercemar minyak bumi menggunakan empat jenis rumput - rumputan yang terdiri dari Eleusine indica, Paspalum notatum, Setaria splendida, dan Stenotaphrum secundatum telah dilakukan. Tujuan utama dari penelitian ini adalah untuk mengetahui efektifitas rumput-rumputan tersebut sebagai tanaman fitoremediasi dalam mengurangi kadar total petroleum hydrocarbon (TPH) pada tanah tercemar minyak bumi. Parameter yang diamati adalah pertumbuhan vegetative tanaman rumput yang terdiri dari biomasa kering, tinggi tanaman, jumlah anakan, dan panjang akar setelah 4 bulan tanam. Selain itu juga dilakukan analisis kadar TPH pada tanah yang telah ditanami rumput-rumputan selama 4; 9; dan 12 bulan. Hasil penelitian menunjukkan bahwa keempat jenis tanaman rumput yang diteliti adalah efektif untuk digunakan sebagai tanaman fitoremediasi tanah tercemar minyak bumi. Persen penurunan TPH tertinggi diperoleh dari rumput Paspalum notatum (38,81%), kemudian Eleusine indica (38,69%), Setaria splendida (36,34%), dan Stenotaphrum secundatum (29,32%)
