Abstract

The rapid evolution of digital technologies has transformed traditional agriculture into a more efficient andintelligent system. This study focuses on the development of a data aggregation strategy in Smart Hydroponic Systems tooptimize network consumption without sacrificing data accuracy. By utilizing Threshold Filtering and Delta-BasedFiltering techniques, significant reductions in data transmission were achieved while maintaining essential temperaturemonitoring capabilities. Experimental results demonstrated that both techniques effectively reduced data points andoptimized bandwidth usage, particularly in temperature-stable environments. This research contributes to theadvancement of sustainable digital agriculture by providing an efficient approach to managing network resources in IoTbasedhydroponicsystems.

Abstract

Penelitian ini bertujuan untuk menganalisis kerentanan keamanan pada aplikasi web e-commerce Kopi Lampung Nusantara menggunakan standar Open Web Application Security Project (OWASP) sebagai acuan utama. Standar OWASP Top 10 diterapkan untuk mengidentifikasi jenis-jenis kerentanan paling umum yang memiliki risiko tinggi terhadap aplikasi web. Metode penelitian melibatkan pengujian penetrasi yang bertujuan untuk mengungkap potensi celah keamanan yang dapat mengancam keamanan data pengguna serta integritas sistem. Hasil pengujian menunjukkan adanya beberapa kerentanan kritis, termasuk PII Disclosure yang berisiko terhadap privasi pengguna, absennya Anti-CSRF Tokens yang meningkatkan risiko serangan Cross-Site Request Forgery (CSRF), serta kurangnya header keamanan seperti Content Security Policy (CSP) dan X-Content-Type-Options. Temuan ini menggarisbawahi pentingnya penerapan standar keamanan OWASP dalam pengembangan dan pemeliharaan aplikasi web, terutama pada sektor e-commerce yang rentan terhadap serangan siber.

Abstract

Attendance system in an institution is very important to implement. In fact, an attendance is a gauge of how performance, discipline, job achievement, salary/wages, and productivity of an employee, as well as general progress of the agency. Especially for agencies that have employees of ASN (State civil apparatus), attendance systems must be held to evaluate how ASN responsibilities to the legislation explaining the ASN. Thus, the creation of personnel attendance system using an IOT-based fingerprint (Internet Of Things), is a way of producing an appropriate and effective attendance device for ASN employees in an institution. The attendance device has the advantage of using the fingerprints of each employee in the process of the system, making it very effective to implement. In addition, the attendance process will automatically enter the employee data that does the attendance to the database, then can be accessed by the Web dashboard Using THE media Rest API. The creation of attendance device implements Scrum method, because this method is effectively applied in the creation of group projects. An evaluation of the device's performance was carried out using the SUS (System Usability Scale) method and resulted in a score of 75 out of 31 respondents. The rating is stated in the Good category and is suitable for use based on the results of the evaluation.

Abstract

Digitalisasi UMKM merupakan langkah strategis untuk meningkatkan daya saing di tengah tantangan globalisasi dan persaingan pasar yang semakin ketat. Kegiatan Pengabdian Kepada Masyarakat (PKM) Inovokasi ini bertujuan untuk mempercepat transformasi digital UMKM Dapur Oma Cinta melalui pelatihan pemasaran digital yang terstruktur. Permasalahan utama yang dihadapi UMKM ini adalah keterbatasan akses pasar dan kurangnya optimalisasi teknologi digital dalam pemasaran produk. Metode yang digunakan meliputi tahapan persiapan, pelaksanaan, monitoring, dan evaluasi. Pada tahap persiapan, tim menyusun materi pelatihan dan menyiapkan sarana pendukung. Tahap pelaksanaan dilakukan melalui sesi pelatihan interaktif dan pendampingan langsung yang mencakup pengelolaan website e-commerce, marketplace, media sosial, dan strategi pembuatan konten digital. Evaluasi keberhasilan dilakukan melalui pre-test dan post-test untuk mengukur peningkatan kemampuan peserta. Hasil menunjukkan peningkatan signifikan dalam pemahaman dan keterampilan peserta terkait pemasaran digital. Rata-rata peningkatan skor post-test peserta mencapai 66,84%, dengan peningkatan terbesar pada peserta dengan pengetahuan awal yang rendah. Temuan penting menunjukkan bahwa pelatihan ini berhasil membantu UMKM memperluas jangkauan pasar, meningkatkan efektivitas promosi, dan memperkuat daya saing di pasar lokal. Kesimpulannya, program ini tidak hanya mendukung transformasi digital UMKM Dapur Oma Cinta tetapi juga memberikan model pelatihan yang dapat direplikasi untuk UMKM lain di Indonesia. Transformasi digital yang dicapai melalui kegiatan ini berpotensi besar untuk meningkatkan pendapatan dan keberlanjutan usaha mitra dalam jangka panjang.

Abstract

The integration of IoT in smart agriculture facilitates real-time environmental monitoring and efficient farming operations. However, the sensitive nature of data in transit presents significant security challenges, primarily due to threats like data interception and unauthorized access. This study explores the implementation of AES-128 encryption as a solution to secure data transmission within a smart agriculture IoT system. Utilizing NodeMCU microcontrollers with DHT22 sensors, this research investigates the encryption and decryption of environmental data (temperature and humidity) through the MQTT protocol, with Node-RED providing data visualization. Experimental results indicate that AES-128 encryption adds minimal overhead, maintaining real-time system performance while safeguarding data integrity and confidentiality. This encryption framework not only reinforces secure data transmission but also enhances decision-making reliability in agricultural management, underscoring the practical benefits of data security in IoT-based smart farming.

Abstract

Sentiment analysis of mobile application reviews supports service evaluation in the fast-growing Indonesian digital finance sector. This study compared an English lexicon-based method (VADER) with a fine-tuned Indonesian RoBERTa model on 1,000 reviews of the DANA e-wallet application collected from Google Play. Following best practice for transformer models, reviews were classified primarily from their original (raw) text, and a preprocessed variant was used to assess the effect of text cleaning. On raw text, VADER labelled 903 reviews as neutral, 78 as positive, and 19 as negative, whereas Indonesian RoBERTa produced 494 positive, 385 negative, and 121 neutral, a positive-leaning distribution consistent with the sample's mean rating of 4.06. Inter-method agreement was negligible (Cohen's kappa = 0.008). Removing stopwords and numbers before classification changed 30.2% of the RoBERTa labels and flattened its distribution, confirming that such preprocessing degrades the contextual input transformers rely on, while leaving VADER almost unchanged. Because no human-annotated gold standard was used, the reported figures reflect inter-method agreement rather than absolute accuracy against human labels. The findings show that VADER is unsuitable for Indonesian reviews and that language-specific transformers should be applied to unprocessed text.
