Abstract

Nutritional problems in toddlers in Indonesia are still high, with a significant prevalence of stunting. Poor appetite in children aged 2 to 6 years is a major factor affecting their nutritional status. One proposed non-invasive solution is aromatherapy with Cymbopogon Citratus (lemongrass), which is known to be calming, stimulating the digestive system, and increasing appetite through stimulation of the olfactory nerve. A quantitative approach was used, involving the participation of children from PAUD Kinta Anak Ceria. This study used a quasi-experimental method with a one-group pretest-posttest design without a control group. Before the administration of aromatherapy, a pretest was conducted to measure the level of children's appetite. After the intervention with Cymbopogon citratus aromatherapy, a posttest was conducted to assess the changes that occurred. This study revealed the effect of Cymbopogon Citratus aromatherapy on the appetite of children at PAUD Kinta Anak Ceria. With a quantitative Quasi-Experiment design, 20 children were observed before and after the administration of aromatherapy for two weeks. The results showed a significant increase in appetite, from an average of 46.00 to 80.25 with a P-Value of 0.000. In conclusion, Cymbopogon Citratus aromatherapy is effective in increasing children's appetite and is recommended to be applied more widely, involving families and educational institutions, and supported by health workers to ensure its safe and effective use.

Abstract

Proses pencarian kerja dan proses rekrutmen secara konvensional dinilai kurang efektif dan efisien dari segi biaya dan waktu. Untuk membantu para pencari kerja dalam mendapatkan pekerjaan yang diinginkan dan membantu penyedia kerja dalam mencari kandidat potensial, diperlukan sistem rekomendasi. Sistem rekomendasi pekerjaan yang ideal harus dapat memenuhi beberapa tujuan seperti merekomendasikan pekerjaan yang paling relevan kepada pengguna, memastikan bahwa setiap posting yang diposting akan menerima sejumlah lamaran dari kandidat yang memenuhi syarat dan memastikan bahwa setiap pekerjaan yang diposting tidak menerima terlalu banyak. aplikasi. Untuk mengatasi masalah ini, metode sistem rekomendasi dapat diterapkan. Salah satu metode yang dapat diterapkan adalah metode Fuzzy C-Means (FCM). FCM menggunakan model pengelompokan fuzzy sehingga data dapat menjadi anggota dari semua cluster yang dibentuk dengan derajat atau tingkat keanggotaan yang berbeda, yaitu antara 0 dan tingkat data dalam satu cluster ditentukan oleh derajat keanggotaan. Hasil dari penelitian ini adalah sebuah website rekomendasi pekerjaan yang menerapkan metode Fuzzy C-Means yang mampu memberikan rekomendasi lowongan kerja kepada pengguna berdasarkan kualifikasi dan jurusan yang dimiliki. Website juga menyediakan fasilitas untuk menguji metode Fuzzy C-Means.

Abstract

The advancement of information technology has driven digital transformation in various sectors, including Micro, Small, and Medium Enterprises (MSMEs), which are vital to Indonesia's economy. However, local MSMEs still face challenges in online transactions, especially related to data security and low consumer trust. Issues like data manipulation, lack of transparency, and weak security systems hinder optimal digitalization. This study implements the SHA-256 cryptographic algorithm in a blockchain system to enhance security and trust in local MSMEs' online transactions. SHA-256 is chosen for its ability to produce unique, permanent, and tamper-resistant hashes. The system adopts a decentralized blockchain model, where transactions are recorded in encrypted, chronologically linked blocks. The testing results show that the SHA-256-based blockchain system functions effectively in maintaining data integrity and preventing manipulation. Black Box Testing confirmed that the system operates correctly from the user's perspective, including login validation, transaction recording, manipulation detection, and transaction history retrieval. White Box Testing validated the internal logic of the system, proving the correct implementation of SHA-256 hashing, block linking, Proof of Work (PoW), and transaction validation mechanisms. All test cases passed successfully, demonstrating that the system is stable, functional, and secure.
