Abstract

Penundaan pemilu Indonesia menjadi isu terhangat dan kontroversial baru-baru ini. Isu ini dilontarkan pertama kali oleh ketua umum PKB, Muhaimin Iskandar setelah menerima pelaku UMKM, pengusaha dan para analis ekonomi di ruang Delegasi DPR RI, Nusantara III, Jakarta pada Rabu, 23 Februari 2022 [14]. Isu penundaan pemilu ini menyebabkan sentimen publik terpecah menjadi tiga, yaitu sentimen negatif, netral, dan positif. Untuk mengetahui persentase sentimen terbesar, diperlukan suatu analisis  sentimen terhadap data cuitan twitter pada periode waktu 1 Januari 2022 sampai dengan saat penelitian ini dilakukan (27 Mei 2022). Dengan menggunakan model Naive Bayes Classifier, kita mencoba memetakan analisis sentimen sebelum Muhaimin Iskandar mengutarakan isu (31.840 data cuitan) dan setelah Muhaimin Iskandar mengutarakan isu (151.878 data cuitan). Analisis sentimen di durasi waktu sebelum Muhaimin Iskandar mengutarakan isu diperlukan untuk mengetes, apakah klaim penundaan pemilu adalah keinginan rakyat adalah benar. Sedangkan analisis sentimen di durasi waktu setelah Muhaimin Iskandar mengutarakan isu diperlukan untuk melihat polarisasi di twitter, seberapa besar dukungan maupun penolakan terhadap isu tersebut. Hasil penelitian yang dilakukan menunjukkan masyarakat baru membahas isu penundaan pemilu setelah dibahas oleh Muhaimin. Sedangkan sentimen terhadap isu penundaan pemilu setelah dilontarkan oleh Muhaimin cenderung menunjukkan sentimen positif sebesar 60.581 cuitan unik, dengan  58.998 cuitan unik yang menunjukan sentimen negatif, sedangkan sisanya, yaitu sebesar 32.291 menunjukkan sentimen netral.

Abstract

The use of blockchain technology in Decentralized Finance (DeFi) has gained popularity, with 23 public companies and one country holding bitcoin. DeFi aims to create an open and decentralized financial ecosystem that is accessible to everyone, eliminates intermediaries like financial institutions, and is verifiable, immutable, globally accepted, fast, low-cost, anonymous, and non-custodial. Despite its benefits, the rapid growth of DeFi has led to increased security risks. This study assesses the validity of DeFi's superiority claims in light of security incidents and events in 2022 and Twitter trends. This study used a Systematic Literature Review from various research articles and news from 2022. This research found that DeFi's superiority claims seem to be inconsistent with what is being advertised. It also found that if DeFi is not properly prepared and audited, its strength (Anonymous, open-source, decentralized, non-custodial, eliminates third parties and regulation) may become its weakness. Despite this, users still exhibit high levels of trust and optimism, as seen in the most popular terms shared by user tweets during significant losses, with 301,654 unique tweets between April 30 and May 31, 2022 and 344,519 unique tweets between October 3 and December 3, 2022, that are crypto, nft, and blockchain.

Abstract

From 2017 to 2022, the Department of Administrative and Bureaucratic Reform assessed the SPBE index of various government agencies with the aim of improving public services and community engagement through technology. In this context, assessing the accessibility of a website or an information system is a simple way of assessing the convenience for the public to access a website or a government information system. government. This study aims to test the accessibility of websites belonging to the three district/city governments with the highest SPBE scores in 2022, Surakarta City, Surabaya City and Denpasar City in terms of usage. WCAG standards. The tests were performed using three accessibility automation tools, namely aXe, WAVE and siteImprove. As a result, despite their high SPBE scores, Surabaya and Surakarta still had a number of accessibility issues that needed to be resolved.
