Abstract

Abstrak: Wangi Persada merupakan kelompok tani akar wangi terletak di daerah Kp. Legok Pulus Ds. Sukakarya Samarang Garut telah menjadi mitra Sekolah Tinggi Teknologi Bandung dalam melakukan kegiatan pengabdian masyarakat. Analsisi masalah yang terjadi di lapangan, yaitu penyulingan minyak atsiri dan kejernihannya, petani masih melakukan penjualan minyak keruh, atau menjaul tumbuhan akar wangi dikebun pada tengkulak dari pada diolah menjadi minyak atsiri, dikarenakan alat penyulingan dan harga minyak keruh yang selama masih belum berpihak pada petani atau dibanderol dengan harga murah. Tim Abdimas bertindak merancang dan menerapkan metode penyulingan secara fisika dengan redestilasi untuk proses pemurnian minyak menggunakan bahan kaca, pembakarannya menggunakan heater dan energi listrik sebagai sumber energinya. Hasil pemurnian yang optimal didapatkan dari kombinasi minyak keruh dan ditambahkan air (aquades). Minyak atsiri yang sudah jernih dapat meningkatkan harga jual dari minyak atsiri yang masih keruh/hitam. Rendemen sisa destilasi dapat dimanfaatkan oleh masyarakat menjadi produk turunannya melaui home industri, sehingga dapat mempengaruhi dan meningkatkan perekonomian petani minyak atsiri akar wangi. Abstract:  Wangi Persada is a vetiver farmer group located in the area Kp. Legok Pulus Ds. Sukakarya Samarang Garut has become a partner of the Sekolah Tingi Teknologi Bandung carrying out community service activities. Analysis of the problems that occur in the field, namely the distillation of essential oils and their clarity, farmers are still selling turbid oil, or selling vetiver plants in the garden to pirates instead of being processed into essential oil, due to distillation equipment and the price of turbid oil which has not been on the side of farmers or at a low price. The Abdimas team designed and implemented physical refining methods with redistillation for the process of refining oil using glass, combustion using a heater and electrical energy as the energy source. The optimal purification results are obtained from a combination of turbid oil and water. Essential oils that are clear can increase the selling price of essential oils that are still cloudy/black. The residual yield of distillation can be utilized by the community into derivative products through the home industry, so that it can affect and improve the economy of vetiver essential oil farmers.

Abstract

Currently, the growth of internet users has been accompanied by the development of applications that support interaction among users, which is called social media. One of the popular social media in society today is twitter. Data on Twitter can be presented in a graph structure visualization in nodes that represent actors and edges that represent relationships between actors. In an effort to find the most influential actors and actors who interact the most in spreading the Natuna topic on social media twitter, an analysis will be carried out using the Social Network Analysis method using the Degree Centrality approach. The data used in this study were taken from December 20, 2019 at 00.00 WIB to January 7, 2020 at 10.00 WIB consisting of 71,477 nodes and 147066 edges. The results of this study can be concluded that the @susipudjiastuti account is the most influential actor and plays an important role in social networking because the @susipudjiastuti account is the most linked account with 29755 links. Meanwhile, the @ shaktia704 account was the most active account during the data collection period, which reached 259 links.
