Abstract

Background: The scientific-based jamu development program enables the development of medicinal plants in the traditional medicine system that eventual-ly can be used in the formal healthcare system. Baturraden and Sumbang are considered as areas with abundant plant biodiversity in Java, where the local community has used those plants for medicinal purposes.Objective: This study is conducted to qualitative and quantitatively record and conserve the knowledge of the Baturraden and Sumbang community on the utilization of plants for treating diabetes mellitus.Method: The data of the plant’s local names, plant organs, methods of prepara-tion, and routes of administration of the herbal preparations used for treating diabetes mellitus were collected through semi-structured interviews with 97 informants. The species use-value (SUV), the relative frequency of citation (RFC), and fidelity level (FL) of each species were calculated accordingly to determine their relative importance and value to the local community.Result: There were 11 plant species from 10 families mentioned. The most commonly used plant organ, preparation method, and administration route were leaves, decoction, and oral, respectively. The most important and valuable plants were including Piper ornatum (SUV = 0.19, RFC = 0.13, FL = 23.09%) and An-drographis paniculata (SUV = 0.09, RFC = 0.07, FL = 42.86%).Conclusion: As the most critical antidiabetic plant in the studied area, the decoction or infusion of Piper ornatum leaves is taken orally 1-2 times a day. However, there are no reports on its anti-diabetic-related activities available to date. In contrast, the uses of Andrographis paniculata as the antidiabetic agent has been widely proven. Baturraden and Sumbang people orally consumed the decoction of this plant’s leaves once a day for the said purpose

Abstract

Efisiensi pengelolaan stok barang dagangan menjadi tantangan penting dalam operasional toko kecil, toko kelontong, dan swalayan. Kekosongan atau kelebihan stok dapat menyebabkan kerugian finansial, penurunan kualitas layanan, serta potensi kerusakan barang, terutama pada produk segar. Pemantauan stok secara manual seringkali tidak efektif dan rawan kesalahan. Untuk mengatasi masalah ini, penelitian ini menyajikan sistem pemantauan ketersediaan stok berbasis Internet of Things (IoT) yang memanfaatkan sensor berat untuk mendeteksi perubahan stok produk secara real-time. Sistem dirancang dengan mengikuti model pengembangan Waterfall, dimulai dari tahap analisis kebutuhan, perancangan perangkat keras dan lunak, implementasi, pengujian, hingga evaluasi pemeliharaan. Mikrokontroler ESP32 digunakan sebagai pengolah data dari sensor berat, yang kemudian dikirimkan ke platform IoT melalui aplikasi Blynk untuk memberikan notifikasi otomatis saat stok mulai menipis. Data dapat diakses melalui perangkat pintar untuk memastikan pengisian ulang stok dilakukan tepat waktu. Berdasarkan pengujian, sistem ini mampu meningkatkan efisiensi pengelolaan stok hingga 30% dibandingkan metode manual, mengurangi risiko kekosongan dan kelebihan stok, serta meminimalkan kerusakan atau pembusukan pada produk segar. Penelitian ini berkontribusi signifikan terhadap pengembangan teknologi IoT, khususnya dalam manajemen stok barang dagangan, dengan mendukung efisiensi operasional toko kecil dan swalayan serta meningkatkan kepuasan pelanggan melalui penyediaan produk segar sesuai permintaan.

Abstract

The Point of Interest (POI) represents a specific geographic location defined by its coordinates, including longitude and latitude, and holds value as a site of interest or utility. Examples of POIs include tourist attractions, hotels, restaurants, ATMs, pharmacies, health centers, retail shops, gas stations, and other categories integral to modern navigation systems. PT. Telkom Klaten has faced increased demands to conduct POI surveys efficiently, driven by advancements in technology that call for faster and more streamlined processes. A primary challenge in these surveys is the selection of an optimal route that minimizes time, costs, and fuel consumption, given that the company currently relies on manual input in Google Maps to determine distance and travel time. This manual approach may hinder survey efficiency and increase operational costs. To address this, an application employing the Dijkstra algorithm was developed to determine the shortest route effectively. The Dijkstra algorithm, known for selecting edges with minimal weight to connect sequential nodes, requires defined origin and destination points, thereby generating the most efficient route between them. This study applies the Dijkstra algorithm to optimize survey routes by modeling them as graph-based routes, aiming to identify the shortest and most efficient paths between multiple POI locations. The findings indicate that the Dijkstra algorithm significantly reduces travel distance and time, thereby achieving notable savings in fuel and operational time for POI surveys.
