Infiltration Wells as a Solution to Runoff and Flooding Problems in Purwodinatan Subdistrict Semarang City
During the rainy season or under heavy rainfall events, roads in Purwodinatan Subdistrict, Semarang City, frequently experience water ponding. This condition disrupts community activities and other road users. Insufficient drainage capacity to accommodate rainfall volume, along with inadequate drainage maintenance that leads to sedimentation, contributes to surface runoff and water inundation. These conditions require further mitigation measures to control surface runoff and shorten the drainage recession time. Therefore, the planning of infiltration wells is proposed as an alternative solution to address this problem. The implementation method adopted in this study consists of a literature review related to the design dimensions of infiltration wells, followed by the calculation of the Bill of Quantities (BoQ). The planning conducted represents a preliminary approach and is solely based on a literature review of infiltration well design, without involving detailed technical analyses of infiltration well capacity. Based on the BoQ calculation, a cost of IDR 6,462,954.92 is required to construct one infiltration well along the Bubakan Baru Street segment, where 9 infiltrations well locations are identified within a single road segment. The final outputs of this activity include a map of proposed infiltration well locations and the BoQ calculation to be submitted to the subdistrict authority. This activity serves as a preliminary planning stage to assist the community in estimating the dimensions, number of locations, and cost of infiltration wells.

Toward a Regional Energy Future: Opportunities and Challenges for Cross-Border Renewable Power Integration in West Africa
Achieving reliable, affordable, and sustainable electricity access remains a critical challenge for power systems in West Africa. Although the region possesses abundant renewable energy resources, fragmented national planning and limited cross-border transmission interconnections continue to restrict optimal resource utilization. This study investigates the technical, economic, and institutional implications of cross-border renewable power integration within the ECOWAS regional power system. Power system modeling was conducted using the PyPSA platform, representing a 14-bus regional network simulated over a full annual operating cycle with high-resolution demand and generation profiles. Three operational scenarios were assessed: Business-as-Usual, private-led Power Purchase Agreements (PPAs), and Coordinated Regional Integration. System performance was evaluated using system marginal costs, renewable energy penetration, transmission utilization, and reliability indices. The results indicate that the Coordinated Integration scenario significantly outperforms the other scenarios, achieving up to a 36% reduction in average system marginal costs, renewable energy penetration exceeding 60%, and improved grid reliability through enhanced load balancing and reserve-sharing mechanisms. In contrast, the Business-as-Usual and PPA-based scenarios exhibit lower performance due to inefficient transmission utilization and institutional fragmentation. The findings highlight that infrastructure expansion alone is insufficient to ensure optimal regional power system performance. Effective integration requires harmonized operational standards, consistent regulatory frameworks, and strengthened regional institutions. Enhancing the roles of the West African Power Pool (WAPP) and the ECOWAS Centre for Renewable Energy and Energy Efficiency (ECREEE), supported by performance-based regional investment mechanisms, is essential to unlock the full benefits of cross-border energy cooperation. This study provides a technically grounded and policy-relevant framework to accelerate energy transition, improve power system resilience, and foster economic integration across West Africa.

Combining long-term energy planning using the Long-range Energy Alternatives Planning (LEAP) system, short-term economic dispatch modeling via PLEXOS, and power flow simulations through OpenDSS, the analysis evaluates three grid development scenarios: Business-As-Usual (BAU), Intermediate Renewable Energy (RE), and High Renewable Energy (RE) integration. The results demonstrate that increasing the share of solar and wind generation to 60% significantly lowers total generation costs, from $3.1 billion under BAU to $2.18 billion in the High RE scenario, while reducing CO₂ emissions by over 60%. Battery energy storage systems (BESS) and demand-side management (DSM) were found to be essential enablers of system flexibility, reducing curtailment and unserved energy, and improving peak load balancing. Voltage stability improved markedly with the deployment of inverter-based control and distributed storage, achieving over 97% compliance with voltage limits in the High RE scenario. Regional integration through the West African Power Pool (WAPP) further enhanced system performance and delivered net trade benefits. The study concludes that Nigeria’s grid can accommodate high renewable energy shares without compromising technical reliability or economic efficiency. These findings offer critical insights for policymakers and energy planners, emphasizing the need for regulatory reform, targeted infrastructure investments, and regional cooperation to achieve a sustainable and resilient energy future.

Evaluating the Role of Advanced Energy-Efficient Technologies in Promoting Sustainability in Nigeria's Construction Industry
This study evaluates the impact of advanced energy-efficient technologies on sustainability within the Nigerian construction sector, focusing on their effects on energy consumption, cost reduction, environmental benefits, and social impacts. A quantitative research approach was employed, using structured questionnaires administered to a total of 123 construction professionals across 150 infrastructure projects in Nigeria. The respondents included architects (n=30), civil and structural engineers (n=38), project managers (n=32), and other construction specialists such as quantity surveyors and support staff (n=23). The analysis included descriptive statistics, ANOVA, and multiple regression analysis to evaluate the relationships between technology adoption and sustainability outcomes. The results indicate strong consensus among respondents that energy-efficient technologies lead to reduced energy consumption (mean=4.2, SD=0.83) and long-term cost savings (mean=4.0, SD=0.92). Environmental benefits were rated highly (mean=4.3, SD=0.68), while social impacts were perceived as less significant (mean=3.7, SD=0.75). ANOVA results revealed statistically significant differences in perceptions based on professional roles (F(3,119)=5.24, p=0.002), with architects showing the strongest agreement regarding the effectiveness of these technologies. Multiple regression analysis identified perceived cost savings (β=0.34, p<0.001) and environmental impact (β=0.29, p<0.001) as the most influential predictors of technology adoption, followed by stakeholder awareness (β=0.22, p<0.001) and social benefits (β=0.15, p=0.003). The model accounted for 76% of the variance in adoption rates (R²=0.76), suggesting robust explanatory power. These findings highlight the critical role of advanced energy-efficient technologies in promoting sustainability in the Nigerian construction sector. They also emphasize the need for targeted educational programs and policy reforms to improve stakeholder awareness, especially of the social and community benefits, to drive broader and more inclusive adoption.
Penggunaan Bahasa Indonesia oleh Generasi Muda Malaysia di Media Sosial dan Dampaknya terhadap Bahasa Melayu: Sebuah Analisis Wacana Kritis
In the era of globalization and the development of digital technology, cross-cultural and cross-linguistic interactions are intensifying, particularly among the younger generation. Social media has become a new space for shifting linguistic practices that reflect the dynamics of identity and power. This study aims to analyze the phenomenon of the use of Bahasa Indonesia by Malaysian youth on social media and its impact on Malay through the Critical Discourse Analysis (CDA) approach of Norman Fairclough's model. This study uses a qualitative method with a case study design, which examines data in the form of social media content and news articles related to changes in language use in online interactions of Malaysian youth. The results of the study indicate a significant shift in language use patterns, where Bahasa Indonesia, especially informal and slang varieties, are increasingly used in online communication, replacing the role of Malay in informal contexts. This process is influenced by exposure to social media and cross-border entertainment content, which creates a hybrid form of communication between the two languages. From a CDA perspective, this phenomenon illustrates the power and ideological relationship between Bahasa Indonesia and Malay, where Bahasa Indonesia is considered dominant in the digital realm, while Malay struggles to maintain its identity as the national language. These findings emphasize the need for a language policy that can balance the preservation of Malay with openness to the influence of other languages, and support the development of dynamic linguistic identities in the context of globalization.

Pendampingan Perencanaan Saluran Irigasi di Desa Sambirejo Kecamatan Wirosari Kabupaten Grobogan
One way to utilize water resources is through the development of irrigation networks. Two common approaches to irrigation planning are the expansion method and the intensification method. Sambirejo Village is one of the areas with extensive land that can be used for rice cultivation. However, due to the large agricultural area, several paddy fields do not consistently receive a water supply from the existing irrigation network. Geographically, Sambirejo Village is located near both large and small rivers, which can be utilized as sources of irrigation water. The main issues faced by the local partners include a lack of understanding in planning irrigation channels to ensure optimal functionality. As a result, existing irrigation systems do not operate as intended, and the community has not yet been able to harness the full potential of the nearby water sources for irrigation purposes. To improve the availability of irrigation water in Sambirejo Village, the activity aimed to provide partners with knowledge on irrigation channel planning, as well as insights into watershed areas that can serve as water sources and the layout of rice fields to be irrigated. The implementation method involved providing explanations on how the irrigation system was designed to utilize gravity flow without pumps, and demonstrating the positive impacts of a properly functioning irrigation network. As a result of the activity, a priority area of approximately 1,200 meters was identified for irrigation channel planning. Technical planning documents were also prepared, including working drawings, channel dimensions, field measurement results, and a cost estimate (RAB), which can be used as a basis for proposing development programs funded by village budgets or related government agencies.
