Abstract

Banyuwangi has a potency as a fishery region. At certain season, the fish production has maximum number. Cold storage is a cooling apparatus which can be used to maintain fish freshness. This research is aimed to get the effect of buffle angle due to temperature distribution of small scale cold storage. The research conduct using model of cold storage with 40 cm length, 30 cm wide and 30 cm height. The model made from styrofoam material. Buffle angle vary as 40o, 50o  dan 60o. Volume flow cooling rate vary with fan voltage input as 6, 9 and 12 Volt. Temperature data are taken using K type thermocouple at 4 measurement points which positioned at the center of cold storage. The result shows that buffle angle has effect due to temperature distribution. The most efficient angle is 60o. The lowest temperature happen at 30 ml/s volume flow rate which is 16,3oC.

Abstract

Traditional classroom-based teaching methods are still used in schools, particularly in Papua’s 3T (frontier, outermost, undeveloped) areas. This highly relies on the teacher-centered method and limits the completion of the curriculum due to time constraints imposed by the schedule. This research aims to design a web-based virtual smart school as a blended learning solution for schools in Papua’s 3T areas. The virtual smart school learning media application is developed using the ADDIE model, a five-step process encompassing analysis, design, development, implementation, and evaluation. This research results in a virtual smart school application that can increase student motivation, enable independent learning, evaluate student learning progress, provide quick access to learning materials, and facilitate interactions between teachers and students at any time or location. The research concludes that virtual smart schools can become a blended learning solution to improve the quality and equity of education in underdeveloped areas of Papua.

Abstract

Kemajuan teknologi erat kaitannya dengan perkembangan ilmu pengetahuan, sehingga tidak dapat dihindari. Salah satu teknologi yang banyak dikembangkan dimana semakin meningkat trending-nya yaitu chatbot, sebuah aplikasi web yang memungkinkan seorang pengguna melakukan percakapan dengan bot, layaknya berinteraksi dengan manusia. Dalam membangun sebuah aplikasi chatbot, tentunya harus memerlukan bantuan bahasa pemrograman untuk membuat aplikasi tersebut. Bahasa pemrograman yang digunakan adalah Python, karena ada banyak pustaka dan kerangka kerja yang dapat membantu untuk menyelesaikan berbagai pekerjaan dengan mudah, termasuk pengembangan aplikasi web. Kebutuhan akan informasi jadwal mata kuliah masih terbatas terutama mahasiswa yang tidak mempunyai telepon genggam. Hal ini menjadi sebuah peluang untuk membuat sebuah aplikasi chatbot layanan jadwal untuk Jurusan Sistem Informasi Fakultas Matematika dan Ilmu Pengetahuan Alam (FMIPA) Universitas Cenderawasih. Tujuan pembuatan aplikasi chatbot tersebut yaitu untuk menunjang proses perkuliahan di salah satu jurusan Perguruan Tinggi Negeri tersebut. Metode yang digunakan dalam membangun aplikasi chatbot yaitu metode Natural Language Processing, yang memungkinkan pemrosesan bahasa alami, sehingga memudahkan pengguna untuk melakukan komunikasi dengan komputer. Berdasarkan hasil dari aplikasi chatbot yang telah dibangun, diperoleh sebuah sistem yang sesuai dengan harapan, yaitu dapat memberikan respon dari berbagai masukan pertanyaan yang berkaitan dengan jadwal oleh pengguna dengan baik.

Abstract

The Vernam Cipher algorithm is a symmetric key algorithm, as it uses the same key for encryption and decryption. It utilizes a binary number system with XOR operation to produce a series of bits. This study aims to implement the Vernam cipher algorithm to secure personal and confidential image data, which is at risk of misuse when shared through chat applications like Facebook, WhatsApp, and email. Therefore, developing image protection applications is crucial. The research explores whether the vernam cipher algorithm, working with single bits in block form and based on binary numbers, can effectively secure image data, specifically grey scale images with BMP and JPG extensions. The approach involves applying the Vernam cipher algorithm to programming language to create a data security application. The outcome is an image security application program, with test results indicating successful encryption with significant randomness. The decryption process with the Vernam cipher method can restore encrypted images to their original state, although some distortion may occur, especially with JPEG images. Decryption of BMP images is nearly flawless. The key for data security can vary in length and form, with encryption taking longer than decryption.

Abstract

Tersedianya stok bahan bakar minyak bio solar sangat penting dalam menunjang kelancaran proses produksi. Didalam proses penerimaan, penyimpanan dan penyaluran perlu diperhatikan untuk menjaga kualitas bahan dan kebersihan bio solar. Sehingga kelancaran proses produksi bisa berjalana lancar, dan tidak terjadi lost rental maupun lost produksi. Pada umumnya, tingkat kebersihan bio solar mengacu pada ISO 4406:2021 dengan Parameter Cleanliness yang dipakai diseluruh dunia tahun 2019 di range 18/16/13. Sedangkan untuk standart acuan yang dipakai dari pihak vendor masih terpaku pada Standar dan Mutu (Spesifikasi) Bahan Bakar sesuai SK Ditjen Migas No. 170.K/HK.02/DJM/2023 tanggal 18 April 2023 belum terdapat pengecekan tingkat kebersihan bio solar yang dikirim. Untuk medapatkan kebersihan bio solar yang disalurkan ke unit sesuai dengan Parameter Cleanliness range 18/16/13 maka perlu dilakukan proses handling yang benar mulai dari peneriman sampai penyaluran ke unit. Untuk dapat meningkatkan kebersihan bio solar tersebut, perlu adanya peningkatan proses handling pada saat penerimaan, pengecekan kebersihan disetiap proses transfer dan flushing dari tangki penyimpanan bio solar tersebut. Dengan implementasi hal tersebut dapat meningkatkan dan menjaga kebersihan bio solar yang disalurkan ke unit

Abstract

Keberadaan tanaman bunga di setiap rumah dapat membuat suasana tenang, sehat, sejuk, dan segar. Kurangnya tanaman bunga yang tumbuh di setiap rumah di Kelurahan Hedam diakibatkan oleh beberapa hal antara lain tanaman bunga tidak dirawat dengan baik khususnya pada musim kemarau. Hal ini terjadi karena penyiraman tanaman bunga hanya dilakukan pada saat ada waktu luang, berbagai kesibukan ibu-ibu yang menyebabkan bunga menjadi layu, kering, dan mati. Tujuan kegiatan pengabdian PNBP Universitas Cenderawasih ini adalah memberikan pelatihan dan praktek kepada ibu-ibu di RT. 02 RW. 04 kelurahan Hedam untuk menerapkan sistem penyiraman otomatis tanaman bunga berbasis teknologi Internet of Things (IoT). Metode kegiatan pengabdian yaitu ceramah, diskusi, tanya jawab, praktek, dan evaluasi penggunaan sistem penyiraman otomatis tanaman bunga. Hasil kegiatan pengabdian adalah mitra memiliki pengetahuan dan keterampilan tentang teknologi IoT pada sistem penyiraman otomatis tanaman bunga. Pelatihan sistem penyiraman tanaman otomatis membantu ibu-ibu di Kelurahan Hedam dalam merawat tanaman bunga agar tidak layu atau mati karena kekurangan air dan penyiraman tanaman dilakukan secara realtime sesuai dengan kebutuhan air berdasarkan kondisi kelembaman tanah.

Abstract

Adolescence is a crucial developmental stage characterized by rapid physical and mental changes that require proper nutrition and sufficient energy intake. At SMAN 1 Batujajar, a significant number of students show signs of anemia, indicating the need for targeted health education. This study evaluates the effectiveness of an anemia-prevention seminar titled “Recharge Your Energy: Unlocking the Secrets to a Productive, Anemia-Free Life” in enhancing students’ knowledge about the causes, symptoms, and prevention of anemia, including the benefits of consuming mung bean juice. Using a quantitative descriptive design, 91 participants completed pre-tests and post-tests, along with health checks such as blood pressure and conjunctiva examinations. Findings revealed that 62 students were clinically identified as anemic. Knowledge levels improved after the seminar, demonstrating increased understanding of iron intake, balanced nutrition, healthy lifestyle habits, and mung bean juice benefits. The program proved effective and is recommended for ongoing school-based health promotion.
