Abstract

Tidak meratanya pembangunan dan berpusatnya kegiatan perekonomian di Jakarta, menyebabkan pertambahan penduduk di Jakarta sangat cepat. Pertumbuhan penduduk yang tidak diiringin dengan lahan untuk pemukiman menyebabkan harga tanah di Jakarta sangat mahal, hal ini menyebabkan masyarakat mencari alternatif di wilayah sub-urban yaitu Tangerang Selatan yang harga tanahnya jauh lebih murah. Dengan Tangerang Selatan yang dijadikan wilayah altenatif, menyebabkan pertumbuhan penduduk yang tidak terkendali. Untuk melihat permasalahan pertumbuhan penduduk yang tidak terkendali atau urban sprawl, peneliti menggunakan metode kuantitatif deskriptif dengan teknik analisis Normalize Difference Built-Up Index dengan membandingkan kota Tangerang Selatan dengan rentang tahun 1993-2023. Hasil menunjukan bahwa terjadi perubahan alih fungsi lahan menjadi area terbangun yang tidak terkendali dari tahun 1993-2023 sebesar 231%, yang dimana perubahan terbesar terjadi padahun tahun 2003-2013 dengan 124% perubahan, lalu diikuti tahun 2013-2023 70%, dan terakhir tahun 1993-2003 37%. Dengan nilai perubahan yang sangat besar ini, perlu peran pemerintah untuk menegaskan perarturan tata ruang kota, agar tidak terjadi permasalahan akibat pertumbuhan penduduk yang tidak terkendali.

Abstract

This community service activity aims to strengthen the marketing strategy of FUNN Maumere as a culinary business operating in an increasingly competitive market environment. The program was conducted using a qualitative descriptive approach through field observations, interviews with business owners and employees, and direct mentoring in implementing more effective marketing strategies. The results indicate that FUNN Maumere has applied a combination of traditional and digital marketing strategies, including brochure distribution and active promotion through social media platforms such as Instagram, TikTok, and Facebook. The mentoring activities focused on optimizing digital marketing, improving service quality, and strengthening brand consistency. These efforts contributed positively to increased brand awareness, customer interest, and wider promotional reach. However, sales performance remains fluctuative due to external factors, such as weather conditions and differences in outlet location characteristics. Therefore, this community service emphasizes the importance of continuous product innovation, enhancement of customer experience, and optimization of digital marketing strategies to reduce dependency on external conditions. This activity is expected to serve as a practical reference and mentoring model for other culinary MSMEs in developing adaptive, innovative, and sustainable marketing strategies to improve competitiveness and business continuity.

Abstract

The global energy transition driven by the challenges of climate change and the mitigation of greenhouse gas emissions has positioned Light Electric Vehicles (LEVs) as a strategic mobility solution in urban environments. The reliability and sustainability of LEV fundamentally depend on the optimization of lithium-ion battery technology, specifically the composition of NCM (Nickel/Cobalt/Manganase) cathode materials. This systematic literature review aims to critically analyze the relationship between the ratio of the elements Ni, Co and Mn to three electrochemical performance metrics, namely specific capacity, Coulombic Efficiency (EC) and capacity retention in the battery life cycle. The PRISMA methodology was applied to identify and screen relevant literature resulting in 12 studies that were included in the analysis. The results of the data review show that there is a fundamental performance dilemma (trade-off) in the NCM cathode. Nickel (Ni) serves as a high specific capacity driver that reaches 220 . However, the proportion of Ni-rich 0.90 to 0.95 is able to increase the sensitivity of the material thereby triggering extreme performance fluctuations and decreased retention due to cation maxing and volumetric instability of the lattice. Meanwhile, Manganase (Mn) and Cobalt (Co) act as structural stabilizers. Mn shows a U-shape performance pattern on EC and retention with a concentration of Mn 0.35 achieves an optimal EC performance of 93%. For Co, a low concentration of 0.05 provides the best balance between EC 93% and capacity retention of 95% although a peak retention point of 98% is achieved at Co 0.15.

Abstract

The increase in the surface temperature of solar panels can reduce their efficiency. This issue can be mitigated through the implementation of cooling systems. One of the currently developed cooling methods involves the use of phase change materials (PCMs). Paraffin is the most commonly used PCM for solar panel cooling systems due to its melting point, which falls within the operating temperature range of solar panels. However, paraffin has a drawback in the form of low thermal conductivity. To overcome this limitation, paraffin is often composited with materials possessing high thermal conductivity, such as graphite. Graphite can also be expanded to alter its mechanical and thermal properties. The expansion of graphite using a solution of H₂SO₄ and K₂S₂O₈ can increase its surface area to 15.669 m²/g and 201.945 m²/g for 5% and 10% solid–liquid variation ratios, respectively. The addition of expanded graphite (EG) can also enhance the thermal conductivity of the PCM to 0.31 W/mK, 0.37 W/mK, and 0.44 W/mK with 5 wt%, 10 wt%, and 15 wt% EG additions, respectively. The paraffin-based PCM cooling system can reduce the average surface temperature by 15.36% and increase the overall efficiency by 0.3%. A PCM cooling system composed of paraffin and expanded graphite (95%/5%) can lower the average surface temperature by 20.32% and increase total efficiency by 0.4%. The PCM system with a 90%/10% paraffin-EG composition can reduce the surface temperature by 32.44% and enhance total efficiency by 1.2%. Meanwhile, the 85%/15% paraffin-EG cooling system achieves a temperature reduction of 32.52% and a total efficiency improvement of 1.27% compared to the system without cooling.

Abstract

The  global  transition  toward  new  and  renewable  energy  sources  to  address environmental issues and the limitations of conventional energy reserves remains a priority. Solar energy,  through  photovoltaic  technology,  emerges  as  a  promising  option  for  mitigating  the environmental  impact  of  traditional  energy.  The  fact  that  solar  energy  is  a  sustainable  resource and a viable means to reduce reliance on fossil fuels supports this. Solar cells are  devices made from  semiconductor  materials  capable  of  converting  solar  energy  into  electrical  energy.  We categorize first-generation solar cells into silicon monocrystalline, silicon polycrystalline, and III- V  single  junctions  based  on  GaAs.  This  article  reviews  the  characteristics  of  first-generation silicon-based  solar  panels,  including  efficiency,  light  absorption,  and  transmission,  which dominate the global market. This review aims to provide an in-depth understanding of the factors influencing the performance of silicon-based solar cells, which will contribute to the development and application of solar cell technology in the future. Keywords: solar energy, solar cell, silicon, monocrystalline, polycrystalline

Abstract

Pencahayaan merupakan salah satu sumber penggunaan energi yang kita pakai sehari hari,  Termasuk pada gedung lembaga pendidikan seperti Gedung Program Studi Fisika Universitas Padjajaran, maka untuk itu Indonesia memiliki standar yang ditentukan oleh BSN SNI 6197:2011. Yang menyatakan bahwa standar pencahayaan 350 lux untuk ruang kelas dan kerja. 500 lux untuk laboratorium, serta 100 lux untuk koridor. Untuk mengetahui apakah standar pencahayaan di gedung lantai 2 ini sudah memenuhi maka Audit Pencahayaan dilakukan pada gedung Program Studi Fisika Universitas Padjajaran Jatinagor yang hasilnya menunjukkan bahwa seluruh ruang kelas, seluruh ruang dosen, dan sebagian besar ruang kinerja tidak memenuhi standar minimal 350–500 lx karena jenis lampu neon 18 watt/1200 lumen, terbilang menjadi luminer yang kurang baik. Nilai lux rata-rata pada setiap ruangan berada jauh di bawah standar, menunjukkan bahwa sistem pencahayaan yang ada tidak mampu menyediakan penerangan yang memadai untuk aktivitas belajar dan bekerja. dan pemakaian biaya untuk lampu neon aktual dan bila memenuhi standar terbilang sangat besar untuk kita dapat alihkan apabila lampu yang digunakan adalah LED dan terbilang bahwa biaya turun jauh sampai nilai 41%.

Abstract

This report aims to describe the application of transformational leadership and its influence on the organizational communication climate at the St. Francis Xaverius Maumere Forestry and Arts Vocational School. Using a descriptive narrative method through interviews and observations, this report illustrates how principals are implementing transformational leadership in school management. The results of the study show that school principals are able to provide inspiration through example, motivation, and continuous support to teachers and education staff. This leadership practice is reflected in the giving of trust, the involvement of teachers in decision-making, and the encouragement to innovate in the learning process. The organizational communication climate in schools is considered open, transparent, and supportive, so that teachers and staff feel comfortable conveying ideas, criticisms, and suggestions without fear. Effective communication between leaders, teachers, and staff helps strengthen teamwork and increase a sense of ownership of the school's vision and mission. Thus, transformational leadership plays an important role in creating a positive organizational communication climate and supporting the improvement of performance and quality of education in schools.
