The Juridical Analysis on Effectiveness of Terrorism Prevention in the Digital Era

This study aims to analyze juridically regarding the effectiveness of preventing acts of terrorism in the digital era. The method in this research is non-doctrinal. Based on the analysis conducted, it was found that currently, the implementation of digitalization-based terrorism prevention has not been able to materialize effectively, this is shown by the increasing recruitment of members of terrorism, financing of terrorism, and the spread of terror through digital media today. Act No. 5 of 2018 in its development has not regulated the implementation of a clear terrorism prevention and the position of the protection and recovery of victims of terrorism is not yet clear and regarding the progress of information and communication technology as a means of terrorism has not been clearly regulated. In addition, it has not yet been regulated related to efforts to prevent and deal with criminal acts of terrorism. So in other words, it can be said that the proliferation of advanced methods of terrorism has not been clearly regulated in the legal politics of handling terrorism

Vehicle Routing Problem by Combining Nearest Neighbour and Local Search

PT. X is a company tasked with distributing Elpiji Gas to major agents. The problem under study is to find a more optimal distribution route so it can maximize the use of other resources, for example the number of trucks used. This distribution problem will be solved by a combination two methods, Nearest Neighbor and Local Search with the hope of getting the shortest route. The way the Nearest Neighbor method works is selecting the Agent's location based on the shortest distance from the last location and improving the solution using Local Search (intra-route insertion (1-0)) by moving one customer's position in one route so that a good distribution route is produce

Sintesis Nanoselulosa dari Limbah Hasil Pertanian dengan Menggunakan Variasi Konsentrasi Asam

Limbah hasil pertanian merupakan sumber serat yang sangat besar. Limbah hasil pertanian banyak terdapat di Provinsi Lampung antara lain adalah jerami padi dan jagung. Pemanfaatan limbah pertanian merupakan salah satu solusi untuk mendapatkan material penghasil selulosa. Nanoselulosa merupakan salah satu pemanfaatan dari selulosa yang sangat bermanfaat bagi kehidupan. Nanoselulosa dapat dibagi menjadi 3 tipe utama yaitu selulosa nanokristal, selulosa nanofibril, dan nanoselulosa bakterial. Nanoselulosa memiliki diameter 1-100 nm dan panjang 500-2000 nm. Beberapa teknik dikembangkan untuk mengekstrak nanoselulosa dari selulosa diantaranya hidrolisis asam, hidrolisis enzimatis, dan proses mekanis. Adapun penggunaan masing-masing metode ekstraksi dimungkinkan menghasilkan tipe dan properti nanoselulosa yang berbeda. Penelitian ini bertujuan untuk melakukan sintesis nanoselulosa dari limbah hasil pertanian dengan berbagai konsentrasi asam untuk menghasilkan selulosa dengan ukuran nano terbaik berkisar antara 1 – 100 nm. Variasi konsentrasi H2SO4 yang digunakan yaitu 45%, 55%, dan 65%. Dari penelitian ini menghasilkan serbuk selulosa dengan ukuran nano yang bervariasi. Ukuran nanoselulosa yang dihasilkan berkisar antara 356,5 nm – 764,2 nm untuk limbah jerami padi, dan 422,6 nm – 634,0 nm untuk limbah kulit jagun

Penapisan Fitokimia, Kadar Kurkuminoid dan Aktivitas Antibakteri Temu Hitam (Curcuma aeruginosa (Christm) Roscoe.), Temu Putih (Curcuma zedoaria Roxb.) dan Temulawak (Curcuma xanthorrhiza Roxb.)

The content of secondary metabolites in the rhizome of the Curcuma genus such as Black turmeric (Curcuma aeruginosa Roxb.), White turmeric (Curcuma zedoaria (Christm.) Roscoe) and Java turmeric (Curcuma xanthorrhiza Roxb.) play a role in various pharmacological activities. One of them is the content of the curcuminoid compounds which have been proved to have antibacterial activity. This study aims to screen the content of secondary metabolite compounds, determine curcuminoid content and verify the antibacterial activity of the extracts of Black turmeric (Curcuma aeruginosa Roxb.), White turmeric (Curcuma zedoaria (Christm.) Roscoe) and Java turmeric (Curcuma xanthorrhiza Roxb.). Extraction was carried out by the maceration method using 95% ethanol as solvent. Phytochemical screening was tested for the content of alkaloid, polyphenols, flavonoids, quinones, tannins, saponins, and steroids/ triterpenoids compounds. Determination of curcuminoid content by UV-Vis Spectrophotometry method. The antibacterial activity test was carried out by the microdilution method against Staphylococcus aureus, Staphylococcus epidermidis, and Propionibacterium acne bacteria. The results of phytochemical screening showed that the three extracts contained polyphenols and flavonoids. Quinone compounds are only contained in the extract of Black turmeric and Java turmeric. Saponin compounds were only detected in Black turmeric and White turmeric  extracts. Meanwhile, steroid/ triterpenoid compounds were detected in the extract of White turmeric and Java turmeric. The results of curcuminoid content determination on the three extracts showed that the Java turmeric extract had the highest content of curcuminoids (16.07 ± 0.023 mg CE/g extract). The results of the antibacterial test showed the strongest activity of the three test samples shown by Java turmeric extract with a minimum inhibitory concentration (MIC) value of 64 mg/mL against Staphylococcus aureus bacteria; 256 mg/mL against Staphylococcus epidermidis bacteria; and 32 mg/mL against the Propionibacterium acne bacteria. These results indicate that Java turmeric extract is more active against Propionibacterium acne bacteria
