Gender mainstreaming (PUG) is a development strategy that integrates gender equality as a key principle in planning and budgeting. The city of Semarang has adopted this approach in various policy documents; however, its implementation still faces significant challenges. This study aims to evaluate the achievement of the seven prerequisites for PUG according to the guidelines from the Ministry of PPPA, including commitment, policies, institutional frameworks, resources, sex-disaggregated data, gender analysis tools (GAP and GBS), and community participation. The research utilizes a descriptive qualitative approach, employing in-depth interviews, document studies, and questionnaires. Key informants include local government organizations (OPDs) and civil society representatives. Data analysis is carried out using Miles & Huberman's interactive model with thematic analysis. The findings show that normative prerequisites such as policies and institutional frameworks are in place, but implementation remains weak, particularly in the use of sex-disaggregated data and the application of GAP-GBS. Supporting factors for success include leadership commitment from specific OPDs and the existence of cross-sector coordination forums, while the main obstacles are limited human resource capacity and insufficient gender-responsive budget allocation. This study reinforces the relevance of policy implementation theory in bridging the gap between normative frameworks and operational practices. Recommendations include ongoing training, mainstreaming sex-disaggregated data, and technical regulations that all OPDs must follow to enhance the effectiveness of PUG.

Energy audits are an essential step in supporting the efficiency of electricity utilization, particularly in large-scale commercial buildings such as shopping malls. This study was conducted to measure and analyze electricity consumption at Pollux Malls Paragon Semarang using a direct measurement approach combined with historical monitoring of energy consumption. The main focus of the audit was on the lighting system and the Heating, Ventilation, and Air Conditioning (HVAC) system from the Basement to the 6th Floor. Measurement results showed that the Energy Consumption Intensity (ECI) ranged between 39.94–45.20 kWh/m²/month, far above the national efficiency standard (maximum 18.5 kWh/m²/month), indicating a highly wasteful energy usage condition. The two main systems contributing to the largest share of consumption were HVAC and lighting, with a combined estimated share exceeding 60% of the total monthly energy use. Based on the analysis, several energy-saving opportunities were identified, including the replacement of energy-efficient lighting (LED), installation of automatic control systems (light, temperature, and timer sensors), and regular maintenance of HVAC systems. With the implementation of technical, managerial, and operational efficiency strategies, it is estimated that energy consumption savings could reach 20–30%, or around 60,000 kWh per month, without compromising visitor comfort.

Inventory management is a crucial aspect in improving operational efficiency, particularly for micro, small, and medium enterprises (MSMEs) such as grocery stores. This study aims to analyze the effect of implementing the First In First Out (FIFO) method on operational efficiency at Reni Grocery Store. Prior to applying FIFO, the inventory system in the store was poorly organized, often resulting in losses due to expired or damaged goods. Since March 2025, FIFO has been implemented by placing older items at the front of the shelves, while new items are consistently placed at the back, accompanied by routine checks of expiration dates. This research employs a qualitative approach using in-depth interviews with the store owner as the main subject. The findings indicate that FIFO positively influences operational efficiency, as reflected by reduced expired goods, improved stock recording, and more organized product flow. These results are consistent with previous studies, such as Pratama & Sari (2020), which showed FIFO reduced losses by up to 25%, as well as Suharto et al. (2021) and Rahman (2022), who emphasized that FIFO enhances stock accuracy and distribution efficiency. Nevertheless, this study also reveals limitations, including limited storage space and a lack of manpower for routine checks, which prevent FIFO implementation from being fully optimal.
