Abstract

An energy audit is a method used to calculate the energy use of a building and find solutions to save energy. Things that can be achieved through this audit process are saving or reducing operational costs for business entities, industry or others, with energy savings also contributing to nature conservation and efficient use of energy which will increase the contribution to the company both financially and the lifespan of the equipment used. longer. From the analysis of the potential for energy savings through audits and conservation, it was concluded that energy use in baby clothing stores is wasteful. This can be seen based on the calculation of the Pre-Eco IKE value, which is 239.6 btu/h. After saving with the ECO option which can be done, the Post-Eco IKE value is 173.1 btu/h, where there has been a decrease in energy consumption from the wasteful category to somewhat wasteful.

Abstract

The advancement of digital technology presents a dual impact on children—on one hand, it offers vast opportunities for learning and interaction; on the other hand, it exposes them to serious threats such as Online Child Sexual Exploitation and Abuse (OCSEA). Central Kalimantan, with its vast geographical area, uneven digital literacy, and limited surveillance infrastructure, is particularly vulnerable to such online crimes. This article aims to examine the effectiveness of the Regional Office for Women and Children Protection (DPPA) in preventing and responding to OCSEA in Central Kalimantan. Using a descriptive-analytical approach, the study highlights four key strategies implemented by the DPPA: public education campaigns, cross-sector collaboration, complaint and victim support services, and local policy advocacy. Findings indicate that while the DPPA has initiated various programs, their overall effectiveness remains low due to limitations in human resources, funding, infrastructure, and inter-agency coordination. Strengthening institutional capacity, expanding outreach, and developing specific local regulations are essential to building a more robust child protection system against online sexual crimes.

Abstract

Coconut milk is prone to spoilage due to its high-water content. Spray drying can extend its shelf life, but conventional cyclone separators often experience re-entrainment and high pressure drop. This study proposes a cyclone separator design with a Circumfluent Cyclone (CFC) structure and a Convergent Vortex Finder (CVF) to improve particle separation. The design was based on analytical calculations involving swirl number and vortex behavior. A prototype with a diameter of 0.11 meters was fabricated and tested under varying air flow rates from 10 to 30 cubic meters per hour and temperatures from 120 to 150 degrees Celsius. The results showed a particle collection efficiency of 100 percent and a minimum pressure drop of 569 pascals. However, this efficiency does not fully represent the actual performance of the cyclone separator because the particles entering the system were large, agglomerated, and oily, which did not match the intended design conditions. Despite this, the modified design successfully reduced reentrainment and improved flow stability.
