Recently, social media platforms such as Twitter, Tumblr, Facebook, YouTube, blogs and discussion forums are being mistreated by radical groups to promote their ideologies and encourage radicalization. Social medias also have been used to create online extremist community and recruit new followers. In this paper work, the authors conduct a schematics literatures review on all available techniques and perform a comprehensive analysis on the application of social media analytic for detecting radical group to understand the circumstances, trends and its gaps. Further, the author provides the characterization, classification and meta-analysis in order to achieve a better understanding of the literature on the extremist detection through intelligent social media. It is found that for over the last 10 years many researchers have been conduct deep investigation on the use of social media analytics on predicting and identifying online radicalization. Besides, data source, features, geolocation, language, machine learning techniques, and tools have been applied on the recent literatures to detect those cyber-extremist activists. This paper also highlighting the performance measurement methods that have been used by researcher for detecting extremist group and radical communities. The goal of this research is to provide an academic base for ongoing research in the developing machine learning algorithm for detecting extremist and radical contents in social medias.
Microtremor is a weak vibration on the surface of the earth that takes place continuously due to sources of vibration such as earthquakes, human activities, industry and traffic (Daryono, 2009). Microtremor data measured obtained 3 signals whose components are vertical (Up and Down), horizontal (North-South), and horizontal (East-West) components. After the signal is obtained it can then be analyzed using the HVSR method and the dominant frequency and amplification values are obtained. The HVSR method compares the spectrum ratio of the horizontal component microtremor signal to its vertical component (Nakamura, 1989). Lhokseumawe City is administratively included in the Province of Nangroe Aceh Darussalam (NAD). In 2004 there was an earthquake of magnitude 9.2 on the Richter Scale in the southern waters of the city of Banda Aceh, which caused a devastating Tsunami. In this event many people lost about 250 thousand lives and lost property that is not small in number (Logan, 2014) Due to the active regional tectonic pattern, the NAD region is a disaster-prone region. The tectonic area of NAD is strongly influenced by the subduction area between the Indian-Australian oceanic plate (Indian Australian Plate) against the European-Asian continental plate (Eurasian plate). The tectonic pattern greatly influences the geological conditions in the waters of the study area. The purpose of this research is to provide preliminary knowledge in the use of microtremors for mapping seismic microzonation. This microzonation mapping is needed for earthquake disaster mitigation purposes, microtremor data analysis can provide information on the value of a place that is very important for earthquake resistant building planning. Building structures that have the same value as the land value will experience resonance in the event of an earthquake. Then the last is the Seismic Vulnerability Index Mapping which is useful for predicting unconsolidated sediment zones at the ground surface when an earthquake occurs, so that further studies for earthquake prone areas can be carried out. The stages of the research method carried out are measuring field data which is divided into several measurement points in each district in the city of Lhokseumawe. At each measurement point, a three-component seismometer is installed to obtain the results of the soil’s vulnerability in the area. Each measurement data is observed for 30 minutes at each point. The results of this study are the existence of areas that are very susceptible to seismic namely Ujung blang and Banda Sakti villages with seismic vulnerability index values (Kg) ranging from 0 cm/s2 -30542.32 cm/s2 The highest value is located at Ujong Blang villages which is 10397.1 cm/s2 This is closely related to the total amount of damage to buildings in Lhokseumawe City due to the 2004 earthquake.
Infeksi daerah operasi (IDO) adalah infeksi yang terjadi baik ditinjau dari insisi ataupun organ/ruang yang terjadi dalam 30 hari setelah operasi atau dalam waktu 1 tahun apabila terdapat implan. Penggunaan madu saat perawatan luka menjadi salah satu langkah untuk mencegah IDO. Madu memiliki berbagai kandungan kimia aktif yang dapat mempercepat proses penyembuhan luka. Tujuan penelitian ini adalah untuk mengetahui efektifitas pemberian madu untuk mencegah IDO pada pasien operasi elektif bedah saraf Rumah Sakit Umum Daerah Dr. Zainoel Abidin Banda Aceh. Penelitian ini merupakan penelitian uji klinis dengan desain paralel. Sebanyak 54 orang pasien operasi elektif venticuloperitoneal (VP) shunt terlibat dalam penelitian dan dibagi menjadi dua kelompo, yaitu kelompok yang mendapat perlakuan dilusi povidone iodine + perawatan luka (Kelompok A) dengan madu dan kelompok dengan perawatan luka standar (Kelompok B) dengan jumlah masing – masing 27 orang. Uji t tidak berpasangan digunakan untuk menganalisis perbedaan skor IDO dengan tingkat kepercayaan 95%. Secara statistik terdapat peredaan yang bermakna skor IDO antar kelompok (p < 0,038) dengan nilai rerata masing – masing secara berurutan 2,30 ± 1,56 dan 3,22 ± 1,62. Madu memiliki tekanan osmotik tinggi dan berfungsi terutama sebagai suatu medium hiperosmolar yang menyebabkan terjadinya aktivitas pembersihan luka dan mencegah pertumbuhan bakteri. Zat yang terkandung memiliki spektrum potensi antibakterial sangat luas yang menghambat pertumbuhan kuman gram positif ataupun negatif, serta kuman aerob ataupun anaerob. Pencucian luka pasca operasi elektif ventriculoperitoneal (VP) shunt di RSUD Dr. Zainoel Abidin Banda Aceh menggunakan dilusi povidone iodine dan perawatan luka dengan madu efektif mencegah infeksi daerah operasi.
This research is focused on evaluating the consistency of research conducted by lecturers on their scientific knowledge. With so many studies and diverse schemes, of course, it also produces varied research. Nevertheless, the quality of research is also the main focus of LPPM. To maintain this, one way to maintain the quality of research is to maintain the consistency of lecturers in researching following their scientific fields. Research that focuses on scientific fields will produce quality research. The products produced can also be accepted by the public and the market. in determining the consistency value of research conducted by lecturers on their scientific disciplines can be achieved with a text mining approach. Using mining and text analysis to gain insight into the topics of lecturer research, it can help writers detect the linear value of research with their field of science. TF-IDF algorithm can recognize the similarity of data in a query that has been stored as a data set. Big data sets greatly affect the success of the system in recognizing the consistency of lecturers’ research titles on their knowledge.
Malikussaleh University (UNIMAL) as a state university in North Aceh has the potential in the form of human resources to play a role in village development. The idea of a greenhouse system for drying coffee beans in Gampong Reuleut Timu was based on the condition of the Corona Virus Disease (COVID-19) Pandemic which dealt a tremendous blow to the economy of the village community. The majority of the people around the institution have house rentals for UNIMAL students. The best solution that academics offer is to turn into small and medium-sized entrepreneurs who can generate additional income. The community can take advantage of their free time by doing a coffee bean drying business with a greenhouse system which has a great opportunity to be developed considering the high intensity of sunlight in North Aceh Regency. The location of this activity is in Reuleut Timur Village, Muara Batu District, North Aceh Regency. The service activity was carried out in two stages, namely an explanation of how to make a greenhouse installation and an explanation of how to dry with a greenhouse system. The outputs are in the form of a service journal system International Review of Practical Innovation, Technology and Green Energy (IRPITAGE) Volume 1, Number 2, December 2021, online publications in the Merdeka News mass media, and an Agreement Document with Geuchik, Reulet Timu Village, Muara Baru District. North Aceh District.
