Abstract

This study analyzes the effect of different saltwater (NaCl) concentrations in the quenching medium on the microstructure, hardness, and corrosion rate of low-carbon steel after the hardfacing process. Hardfacing was performed using a DF2A-450-R electrode, followed by rapid cooling in distilled water containing 3.5%, 7%, and 10.5% NaCl. Microstructure was observed using an Olympus BX51M optical microscope, hardness was tested by the Vickers method, and corrosion behavior was evaluated via electrochemical Open Circuit Potential (OCP) and Linear Sweep Voltammetry (LSV). The results show that higher NaCl concentrations accelerate cooling and promote a more dominant martensitic structure. The 10.5% NaCl specimen achieved the highest hardness of 582.1 HV and exhibited a more positive corrosion potential with the lowest corrosion current. Therefore, the 10.5% NaCl quenching medium provides the optimal balance between hardness improvement and corrosion resistance, making it suitable for post-hardfacing heat treatment of low-carbon steel in demanding industrial applications.

Abstract

This study investigates the effect of oil viscosity as a quenching medium on the hardness and corrosion rate of mild steel after hardfacing. The specimens were quenched using oils of different viscosities (SAE 30, SAE 40, and SAE 50) after hardfacing treatment. Microstructural analysis using an Olympus BX51M optical microscope revealed that lower-viscosity oil produced a more dominant martensitic phase, while higher-viscosity oils resulted in greater formation of ferrite and pearlite due to slower cooling rates. The Vickers hardness test showed the highest hardness value of 460.44 VHN for SAE 30, decreasing to 415.18 VHN for SAE 50. Electrochemical testing indicated that the corrosion current density (Icorr) and corrosion rate increased with oil viscosity, from 95.2 µA/cm² and 1.114 mmpy (SAE 30) to 129.1 µA/cm² and 1.511 mmpy (SAE 50). The results demonstrate that lower-viscosity oils enhance martensitic transformation, improve hardness, and reduce corrosion rate, highlighting viscosity control as a key factor in optimizing post-hardfacing heat treatment performance.

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.

Abstract

Modern residential housing planning faces substantial complexity, spanning regulatory compliance, diverse user preferences, and demands for resource efficiency and sustainability. These challenges are often magnified by insufficient coordination, resulting in inefficiencies and potential errors. Through a purposive literature review, this study addresses a critical gap in the literature regarding conceptual frameworks that integrate architecture and information systems, particularly during the residential planning phase. Information System (IS) integration has become essential, enabling holistic building data management, analysis, and design optimization. Although technologies such as Building Information Modeling (BIM) and Decision Support Systems (DSS) are widely recognized for their potential, existing studies emphasize specific technologies or practical implementations, leaving a need for a more abstract and foundational integrative model. This study develops an innovative conceptual framework model depicting the essential synergy between architectural design principles and information systems capabilities to optimize the planning process. The proposed model positions information systems as the main enabler, supporting data management, analysis, and visualization through an Integrated System that combines BIM, DSS, and the Internet of Things (IoT), producing data-driven, collaborative, and optimized planning outputs. This framework provides a theoretical foundation for future interdisciplinary research in technology-driven residential planning.

Abstract

This study aims to determine whether the islanding-based defense scheme at the Orya hydropower plant can effectively maintain the stability of the Jayapura radial power system during major disturbances. The system was modeled and tested in DIgSILENT PowerFactory under several outage scenarios, with a focus on the separation of the Orya–Sentani–Skyline corridor. The simulation indicates that maintaining post-disturbance operation within the nominal frequency of around 50 Hz and voltage variation of ±5% requires shedding 19.89 MW of load from selected feeders. After the scheme is activated, the islanded Orya subsystem settles at approximately 50.15 Hz, while the remaining grid stabilizes near 50.0 Hz—both within regulatory limits. These findings suggest that a combined load-shedding and islanding strategy can reduce the risk of cascading failures in Jayapura and may offer a practical template for other radial systems with limited redundancy.

Abstract

Brushed DC motors are often used as low-cost prime movers in small generator sets. However, users rarely evaluate thermal safety together with efficiency when the set operates under repeated electrical loads. This study investigates a 24 V, 750 W brushed DC motor mechanically coupled to a 220 V, 50 Hz single-phase synchronous generator and a lamp-based resistive load bank. Three generator load levels were tested (1000 W, 1400 W, and 2600 W). Each test ran for 10 minutes to represent a short-time duty that is practical for repeated laboratory trials and long enough to reveal a clear temperature trend while maintaining safe operation. The DC terminal voltage (V), input current (A), and motor surface temperature (°C) were recorded every 2 minutes. Input power, temperature rise, estimated loss power, output power, and apparent efficiency were then computed at the 10-minute mark. The results show a monotonic temperature rise with load: after 10 minutes, the motor surface temperature reached about 36.0°C (1000 W), 39.3°C (1400 W), and 41.5°C (2600 W), corresponding to a 9–15 K rise above ambient. The apparent efficiency remained high at 94.3–96.3%. These findings support a simple and replicable approach to discussing the thermal safety and efficiency of small motor–generator sets in laboratory practice.

Abstract

Biji kakao merupakan salah satu bahan dasar untuk membuat coklat. Sebelum diolah, biji kakao harus mengalami proses fermentasi dan pengeringan terlebih dahulu. Kendala yang dihadapi oleh petani biji kakao di Indonesia adalah harga mesin pengering biji kakao yang mahal dan perawatan yang tidak mudah. Untuk itu, perlu adanya alat pengering biji kakao yang disesuaikan dengan kebutuhan petani di Indonesia. Metode yang digunakan dalam desain alat pengering biji kakao adalah Quality Function Deployment (QFD). Tahap pertama yang dilakukan adalah melakukan interview kepada petani dan pemilik perkebunan biji kakao, kemudian mengumpulkan data sebagai dasar membuat beberapa varian desain alat pengering biji kakao. Mesin pengering biji kakao paling sesuai ditentukan dengan membuat rating pada setiap variasi mesin. Setelah didapatkan dilakukan perhitungan untuk mendapatkan hasil yang akurat. Dari hasil perhitungan didapatkan mesin pengering biji kakao dengan panjang x lebar x tinggi sebesar 1100 mm x 750 mm x 1350 mm. Poros bahan S45 C-D, pasak S 55 C, V-belt tipe A dan diameter puli 95 mm.
