Abstract

The development of information and communication technology is increasing rapidly from year to year, especially in the field of telecommunications. Communication technology via fiber optic is one of the technologies that is widely used as a data sender, between senders and receivers in one network, users can communicate with each other at very high speeds. This is in line with the community's need for fast communication services. FTTH (Fiber To The Home) is a telecommunications service infrastructure that supports transmission on large bandwidths and can solve bandwidth access problems so that PT. Telkom designs fiber to the home network access using GPON technology by determining its usage.

Abstract

Traditional processing of Arenga sap still faces significant challenges, particularly long heating duration and high energy consumption. This study aims to evaluate the performance and energy efficiency of a solar-powered vacuum evaporator for the concentration of Arenga sap. The solar energy system consists of monocrystalline panels, an MPPT charge controller, a deep-cycle battery, and an inverter as the primary power source for the vacuum pump and induction heater, while thermal insulation is applied to minimize heat loss during evaporation. The performance test was conducted using 40 kg of fresh Arenga sap under a vacuum pressure of –0.71 to –0.73 bar and an operating temperature of 34–41°C for 150 minutes, resulting in 1.10 kg of evaporated mass. Based on the corrected and consistent dataset, the evaporation rate was calculated as 0.44 kg/hour, and the energy analysis using the latent heat of vaporization yielded an overall system efficiency of 83%. The novelty of this research lies in the implementation of a fully solar-powered low-pressure vacuum evaporator equipped with thermal insulation to enhance thermal stability. The findings indicate that this system can operate independently and offers a practical solution for small-scale Arenga sap producers, especially those located in remote or off-grid areas.
