Abstract

Adanya tindak pencurian seringkali membuat pemilik rumah merasa khawatir pada saat meninggalkan rumahnya. Seringkali pemilik rumah melakukan pengecekan berkali-kali untuk memastikan semua pintu telah terkunci dengan baik. Untuk itu diperlukan suatu teknologi yang dapat mengontrol sebagian besar perangkat rumah melalui jaringan internet yang dikenal dengan Internet of Things. Sistem pengunci rumah memungkinkan pengguna dapat mengunci, menutup, memantau, pada rumah tersebut melalui jaringan internet. Sebagai otak dari pengendalian digunakan mikrokontroler ATMega 16 yang menggerakkan relaydengan metode kontrol on-off. Berdasarkan hasil pengujian, pengendalian melalui ponsel ke mikrokontroler memerlukan waktu rata-rata 1 detik dan pengiriman kondisi pintu dari mikrokontroler ke ponsel memerlukan waktu rata-rata 1 detik. Respon waktu yang diberikan dapat bervariasi tergantung dari kondisi kecepatan internet yang dimiliki oleh mikrokontroler maupun ponsel.Kata kunci : Smart home, Security System, Android, Door Lock System.

Abstract

The utilization of residual energy within existing power plant systems represents a promising pathway to enhance energy efficiency and support decarbonization without requiring additional fuel consumption. This study evaluates the feasibility of integrating a micro-hydropower (MHP) system into the condenser cooling water discharge of a coal-fired power plant (CFPP) in Indonesia. A quantitative techno-economic assessment framework is employed, incorporating hydraulic analysis, annual energy production estimation, discounted cash flow (DCF) evaluation, environmental impact assessment, and sensitivity analysis. The results indicate that an average discharge of 1.20 m³/s and an effective head of 8.73 m can generate an actual power output of 77.37 kW, corresponding to an annual electricity production of 610.01 MWh. Economic evaluation shows strong feasibility, with a Net Present Value (NPV) of approximately IDR 3.9–4.0 billion, an Internal Rate of Return (IRR) of about 27%, a Levelized Cost of Energy (LCOE) of approximately IDR 725/kWh, and a payback period of 3.6 years. Sensitivity analysis reveals that capacity factor and discount rate are the most influential parameters affecting LCOE and NPV, respectively, while the system remains financially robust under ±10% variations. From an environmental perspective, the system can reduce carbon emissions by approximately 518 tons CO₂ per year without additional fuel consumption. Compared to conventional river-based micro-hydropower systems, the proposed approach offers higher operational stability, lower resource dependency, and reduced investment risk due to the utilization of continuous industrial flow and existing infrastructure. Overall, the findings demonstrate that integrating micro-hydropower into condenser cooling systems is a technically feasible, economically competitive, and low-risk strategy for improving energy efficiency and supporting incremental decarbonization in thermal power plants. The study contributes to the advancement of infrastructure-based energy recovery approaches and provides a practical framework for industrial-scale implementation.
