Abstract

The expiration of the lock-up period for PT GoTo Gojek Tokopedia Tbk's shares led to a sharp stock price decline and public discourse on Twitter. This study aims to examine the statistical relationship between public sentiment and GoTo’s stock price movement in Indonesia. Tweets were classified into positive or negative sentiment using the Naïve Bayes classifier, selected for its computational efficiency on large-scale textual data. The model achieved 70% accuracy, with a precision of 82% and F1-score of 75%. The sentiment polarity was then compared with stock trends across 39 distinct trading periods using four non-parametric statistical tests: Chi-Square (p = 0.6398), Cramer’s V (0.014), Goodman-Kruskal’s Lambda (0.053), and Mann-Whitney U test (p = 0.8994). None of these tests showed a statistically significant association between sentiment polarity and stock price movement. These findings highlight that while public sentiment may reflect short-term public interest, it does not reliably capture the market’s behavioral dynamics—especially in cases of investor decisions driven by broader macroeconomic or institutional factors. Sentiment data, therefore, should be considered as a complementary, rather than primary indicators in stock price analysis.

Abstract

  This research focuses on the development of an interactive web-based dashboard to support a precision agriculture system for chili plants. The primary focus of this research is on the back-end development of the system. The system integrates several internal and external APIs, including the Flask API (internal) for plant disease classification and growth prediction, and the Google Gemini API for the AI-powered chatbot that provides consultation to farmers (external). These features allow farmers to receive automatic disease diagnosis and growth predictions, improving decision-making and crop management. The dashboard also presents weather information, environmental data, and nanobubble data, along with Echarts gauge charts for seven essential metrics: Electrical Conductivity (EC), temperature, humidity, pH, nitrogen, phosphorus, and potassium. Data for the environmental and nanobubble data is retrieved from the ThingSpeak API (external), while weather information is fetched from the OpenWeatherMap API (external). The system was thoroughly tested using Postman to ensure all API endpoints function correctly. The results confirmed that all endpoints responded with status code 200 OK, indicating stable back-end performance. Performance testing showed response times stabilizing at 2000 ms after initial 4500 ms peaks, confirming efficient handling, reliable endpoints, and deployment readiness.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) play an important role in improving Indonesia’s economicgrowth that has been slowing down during the Covid-19 pandemic, an outbreak that significantly affectedthe national economy. MSMEs contribute 60.51% to Gross Domestic Product (GDP) of Indonesia andabsorb 96.29% of Indonesia’s workforce. In order to boost national economic recovery and growth, thegovernment is stimulating the growth in MSMEs by providing Bantuan Langsung Tunai (BLT) or CashTransfers for MSMEs. In practice, however, there are various problems in relation to the distribution of CashTransfers, such as illegal fees, corruption, misappropriation of funds, and mistargeting. In this paper, wepropose a mobile application design that can be a solution to all those problems. The application is designedto provide easy access for users to submit proposals and track the progress, with the result that the cash isdelivered efficiently and quickly to intended beneficiaries. This is an effort to promote openness andtransparency in public administration and also to prevent corruption that can occur in delivery of cash. Thisapplication, namely “Sumbangsih”, applies a prototype method as the System Development Life Cycle(SDLC), which consists of six phases: planning, analysis, design, implementation, testing, and maintenance.In the final phase, after the application is created, testing is carried out using User Acceptance Test (UAT)to verify that every function of the application is working exactly as required.

Abstract

Abstrak—Perpustakaan merupakan tempat umum untuk mencari buku atau sekedar mencari referensi. Namun semenjak virus covid menyebar di seluruh dunia pada tahun 2019, pemerintah menutup semua tempat umum untuk mencegah penyebaran virus salah satunya perpustakaan. Dikarenakan oleh hal ini banyak masyarakat umum bingung bagaimana cara untuk membaca buku secara gratis dalam keadaan virus COVID-19 masih berkeliaran. Oleh karena itu diperlukan suatu solusi agar masyarakat masih dapat membaca buku secara gratis seperti pada perpustakaan umum. Solusi tersebut ialah membuat suatu website yang berisikan buku digital sehingga masyarakat umum dapat membaca buku kapan saja dan dimana saja tanpa harus keluar rumah. Metode pengembangan website akan menggunakan salah satu metode agile, yaitu extreme programming (XP). Metode extreme programming (XP) cocok diterapkan pada projek berskala kecil dan hanya membutuhkan satu sampai tiga orang saja. Selain metode pengembangan diperlukan juga metode evaluasi untuk menguji kelayakan website. Metode evaluasi yang akan digunakan ada dua yaitu blackbox testing untuk menguji antar muka dan fungsi website dan load testing untuk menguji kapasitas website pada beberapa pengguna. Hasil dari pengujian tersebut akan dijadikan saran untuk pengembangan lebih lanjut agar website menjadi lebih efektif.Kata kunci— web, extreme programming, blackbox testing, load testing

Abstract

The development of computing technology in increasing the accessibility and agility of daily activities currently uses the Internet of Things (IoT). Over time, the increasing number of IoT device users impacts access and delivery of valuable data. This is the primary goal of cybercriminals to operate malicious software. In addition to the positive impact of using technology, it is also a negative impact that creates new problems in security attacks and cybercrimes. One of the most dangerous cyberattacks in the IoT environment is the Mirai botnet malware. The malware turns the user's device into a botnet to carry out Distributed Denial of Service (DDoS) attacks on other devices, which is undoubtedly very dangerous. Therefore, this study proposes a k-nearest neighbor algorithm to classify Mirai malware-type DDOS attacks on IoT device environments. The malware classification process was carried out using rapid miner machine learning by conducting four experiments using SYN, ACK, UDP, and UDPlain attack types. The classification results from selecting five parameters with the highest activity when the device is attacked. In order for these five parameters to be a reference in the event of a malware attack starting in the IoT environment, the results of the classification have implications for further research. In the future, it can be used as a reference in making an early warning innovative system as an early warning in the event of a Mirai botnet attack.
