Abstract

The community has traditionally utilized the swallow’s nest (Collocalia fuciphaga), an edible bird’s net (EBN), as a component in medicines and cosmetics. Within the cave’s walls lies the environment for the swallow’s nest. The nest’s quality and form are taken into account when determining the nest wallet’s selling price. This study intends to ascertain the possible suppression of the bacteria Staphylococcus sp. and Escherichia sp. activity as well as the antioxidant activity of the swallow’s nest from the nest class formed from wood and concrete construction types. The study was conducted directly on dry, hair- and dirt-free, finely powdered, and dissolved in distilled water swallow nests (Collocalia fuciphaga). Testing for antibacterial activity was conducted. Agar well testing for antibacterial activity was carried out using Mueller Hinton Agar (MHA) and chloramphenicol media as positive controls. Ascorbic acid was used as a positive control while 1,1-diphenyl-2-picrylhydrazyl (DPPH) was tested for its ability to scavenge free radicals. The test findings demonstrated that the swallow (Collocalia fuciphaga) had substantial antioxidant activity against DPPH and that the swallow’s nest (Collocalia fuciphaga) had antibacterial activity against Staphylococcus sp. and Escherichia sp. germs. The swallow’s nest’s (Collocalia fuciphaga) antioxidant and antibacterial properties are specific to different nest classes and building kinds, so they may be utilized as a foundation for thought about raising the selling price of bowls, powders, and crumbles in each form of structure.

Abstract

Oil palm plantations in remote regions such as Sebatik, North Kalimantan, face significant challenges in sustainable soil management due to limited infrastructure and dynamic peat soil conditions. Conventional monitoring methods lack real-time capability and energy efficiency. To address this, this research proposes a novel adaptive low-power LoRa-based Wireless Sensor Network (WSN) that dynamically adjusts sensing and transmission frequency based on real-time soil parameters—specifically, moisture, temperature, and pH. Unlike fixed-interval systems, the proposed architecture implements edge-based logic on ESP32 nodes to escalate sampling during critical events (e.g., pH ≤ 4.5) and reduce activity during stable periods, optimizing energy use without cloud dependency. The system integrates LoRa SX1278 modules, a RAK2245 gateway, ChirpStack for secure data routing, and OpenRemote for visualization and alerts. Field testing over 7 days in three micro-zones (roadside, plantation center, drainage) demonstrated robust performance with average Packet Delivery Ratios of 97.2%, 82.5%, and 88.3%, respectively, and a communication range of up to 2.8 km. Crucially, the adaptive strategy reduced daily power consumption to 7.8 mAh—58% lower than a fixed 10-minute schedule—extending theoretical battery life from 6–8 months to over 14 months. Sensor accuracy remained high (moisture error: 1.68%; temperature: 3.09%; pH: 1.47 units), enabling timely agronomic interventions such as targeted liming. This work contributes an environment-responsive WSN architecture that balances energy efficiency and event responsiveness, offering a scalable, deployable model for precision agriculture in tropical peripheral regions with acidic soils and intermittent connectivity.
