Abstract

Untuk pembangunan infrastruktur di Indonesia, sering menggunakan material berupa beton. Beton memiliki kelebihan yaitu mempunyai kuat tekan yang tinggi, mudah dibentuk, dan tahan terhadap temperatur tinggi. Seiring berkembangnya teknologi material, untuk meningkatkan kualitas dan mutu dari beton timbullah berbagai macam inovasi yang dilakukan oleh peneliti. Salah satunya dengan memanfaatkan limbah kaleng minuman sebagai bahan tambah dalam campuran beton. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan serat limbah kaleng minuman sebagai bahan tambah agregat kasar terhadap kuat tekan beton. Metode yang digunakan pada penelitian ini adalah metode eksperimen. Variasi penambahan serat kaleng minuman yang digunakan yaitu 0%, 1%, 2%, dan 3% dari berat agregat kasar. Pengujian dilakukan pada umur beton 14 dan 28 hari. Hasil penelitian tersebut menunjukkan bahwa penambahan 1% serat limbah kaleng minuman memberikan kuat tekan tertinggi sebesar 20,63 MPa, lebih tinggi dari beton normal yaitu 20,17 MPa, dan memenuhi mutu rencana f’c 20 MPa. Namun, pada variasi 2% dan 3%, kuat tekan menurun menjadi 15,18 MPa dan 9,56 MPa. Penambahan serat kaleng minuman sebanyak 1% merupakan komposisi paling optimum. Selain meningkatkan mutu beton, penelitian ini juga memberikan alternatif pemanfaatan limbah kaleng minuman secara ramah lingkungan.

Abstract

One of the government’s policies to address poverty is the Program Keluarga Harapan (PKH). The program aims to improve the socioeconomic, educational, and health conditions of poor communities. This study employed a descriptive qualitative research method, with data collected through observation and in-depth interviews. The findings indicate that the implementation of PKH in the Floating House community of the Fishermen Village in Tallo Subdistrict, Tallo District, Makassar City, has received support from various stakeholders, particularly the Tallo Subdistrict government. The recipients have shown considerable enthusiasm for the program. However, this research is urgent to evaluate the actual impact of PKH on improving the welfare of coastal communities with limited economic opportunities, education, and healthcare access. While the program has gained positive responses, challenges remain in ensuring its sustainability and effectiveness in breaking the cycle of poverty. Therefore, this study is essential to identify existing obstacles in program implementation and offer recommendations for enhancing its effectiveness. The findings are expected to contribute to policy development, ensuring that PKH and similar social assistance programs are better targeted and more impactful in reducing poverty, particularly among vulnerable fishing communities.

Abstract

This study aims to evaluate the impact of digital marketing strategies on consumer purchasing decisions in the retail industry in Bandung City, focusing on consumer sentiment towards sustainable branding. The results of linear regression analysis show that SCBB has a coefficient of 0.710, which means that every one unit increase in SCBB will increase the value of KP by 0.710 units. The t test shows that SCBB has a significant effect on KP (t = 8.875, p = 0.000). The F test shows that the overall regression model is significant (F = 78.75, p = 0.000). The coefficient of determination (R Square) of 0.562 indicates that 56.2% of the variation in KP can be explained by SCBB, with an Adjusted R Square of 0.557.The conclusion of this study is that Consumer Sentiment towards Sustainable Branding (SCBB) has a positive and significant influence on consumer purchasing decisions (KP) in the retail industry in Bandung City. Digital marketing strategies that focus on sustainable branding are proven to be an important factor influencing consumer purchasing decisions. The results of this study provide insight for retail industry players in designing effective digital marketing strategies to increase consumer purchasing decisions through a sustainable branding approach.
