Jejaring sosial adalah sebuah wadah bertemunya berbagai jenis pengguna berikut dengan berbagai jenis kebutuhan informasi dan tujuan pengaksesan. Dengan adanya kondisi tersebut, untuk menjamin keamanan dan kenyamanan privasi pengguna, Anonimitas lahir sebagai “fasilitas minimal’ guna mengamankan informasi personal ketika pengguna sedang berjejaring. Namun seiring perkembangan zaman karateristik pengguna juga berubah, sehingga terjadi pergeseran preferensi penggunaan dan kepatuhan terhadap regulasi serta etika pada saat berjejaring sosial di ruang. Hal tersebut juga menjadi stimultan tumbuhnya malfungsi dari Anonimitas yang mengarah ke tindakan pelanggaran etika sampai dengan tindakan kriminal.Dengan berbagai permasalahan yang terjadi, tulisa ini dimaksudkan untuk menggali pergeseran pola penggunaan dan karakteristik pengguna terhadap munculnya penyimpangan anonimitas di ruang digital, dengan menggunakan konsep kebudayaan dan etika digital. Dengan menerapkan metode studi literatur, penelitian ini bertujuan membentuk suatu pemahaman yang mendalam terkait penggunaan anonimitas di ruang digital. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan paradigma konstruktivis, fokus pada pengumpulan data konsep dan teori serta data pendukung terkait masalah kebebasan berpendapat, anonimitas, budaya partisipasi, dan dominasi subyektivitas pengetahuan di ruang digital dalam rentang waktu 15 tahun (2008-2023). Hasil kajian diharapkan dapat memberikan saran yang dapat diterima oleh semua pihak terkait, serta menjadi bahan diskusi lanjutan dalam konteks yang sama pada masa yang akan datang. Hasil penelitian disimpulkan bahwa Anonimitas dalam ruang digital menciptakan tantangan terkait hak kekayaan intelektual, peningkatan kasus cybercrime, dan akses tidak terkendali terhadap konten kontroversial seperti pornografi, menyulitkan regulasi pemerintah karena kendala teknis.

Corrosion can also be defined as the forced destruction of metal by the surrounding medium which is usually a liquid (corrosive agent). Corrosion prevention processes can be carried out, including by coating the metal surface, cathodic protection, adding corrosion inhibitors and so on. Several types of inhibitors that have been widely used in industrial applications are synthetic chemical inhibitors. However, the compounds of inhibitors are environmentally unfriendly, toxic and expensive. To overcome this problem, it is necessary to develop an environmentally friendly alternative corrosion inhibitor or better known as a green inhibitor. This research aims to test the effectiveness of using a combination of lime (Citrus aurantifolia.), Lerak (Sapindus rarak) and jasmine flower (Jasminum nudiflorum) extracts as an environmentally friendly corrosion inhibitor. The results obtained were inhibitors in the form of a combination which were added to the corrosive medium HCl which could reduce the rate of aluminum corrosion. This research also shows that time and concentration influence the corrosion rate. A higher concentration (200 ppm) has a greater inhibitory power than a concentration of 100 ppm. The best inhibitory power is found in 200 ppm inhibitor with a soaking time of 20 minutes

Published: March 2024

This study addresses the persistent challenge of rice storage and food security, focusing on the post-harvest management of stored grains, particularly in mitigating damage caused by the rice weevil (Sitophilus oryzae L.). The research explores the impact of varying concentrations (2-8 grams) of green betel leaf (Piper betle L.) powder extract on rice weevil mortality. Employing a Completely Randomized Design, the study reveals that the highest mortality (15.6%) is achieved with an 8-gram concentration of green betel leaf powder. Correlation analysis establishes a positive relationship between concentration and weevil mortality (r = 0.84), with a significant correlation (r = 0.77) between concentration and the time taken for weevil mortality. Calculated efficacy demonstrates that the 8 gram concentration achieves a 70% effectiveness, meeting success criteria. Consequently, green betel leaf powder emerges as a promising botanical insecticide against rice weevils, warranting further investigation for dosage optimization and concentration. Future research should prioritize environmental and human safety considerations in the development and application of botanical insecticides in agricultural pest management.
