Abstract

Tapera merupakan program program yang dapat membantu masyarakat mendapatkan rumah yang layak dan terjangkau melalui pembiayaan dana murah berkelanjutan dan berlandaskan gotong royong. Program ini mewajibkan pekerja untuk memberikan iuran sebesar 2,5% hingga 3% dari penghasilan, yang kemudian dikelola oleh Badan Pengelola Tabungan Rakyat (BP Tapera). Penelitian ini bertujuan untuk menganalisis biaya dan manfaat dari kebijakan Tabungan Perumahan Rakyat (Tapera) di Indonesia. Penelitian ini menggunakan pendekatan kualitatif dan kuantitatif dengan data yang bersumber dari BP Tapera, Badan Pusat Statistik (BPS), Bank Indonesia dan sumber resmi lainnya. Hasil analisis menunjukkan bahwa program Tapera memberikan manfaat ekonomi yang signifikan dengan rasio CBA (Cost-Benefit Analysis) yang lebih dari 1, menandakan bahwa manfaat yang diperoleh lebih besar daripada biaya yang dikeluarkan. Namun, terdapat beberapa tantangan yang perlu diatasi, seperti transparansi pengelolaan dana dan peningkatan partisipasi pekerja dalam program.

Abstract

Indonesia possesses significant mineral resources, making it a crucial player in the global mining industry. This research aims to examine the interests of critical stakeholders including the government, mining companies, local populations, and environmental groups to ensure the long-term viability of the downstream mining sector. The study aims to identify the dynamics of relationships and interests. It reveals that conflicts of interest exist, and if not managed effectively, they may impede the industry's progress. However, there are opportunities for collaboration that, if maximized, can boost added value for all stakeholders, including enhancing the welfare of local communities. The consequences of this research include legislative recommendations to the Indonesian government for the establishment of more inclusive legislation and ways for businesses to improve their interactions with local communities and other stakeholders. The implications of this research include legislative recommendations to the Indonesian government for the establishment of more inclusive legislation, as well as ways businesses can improve their engagement with local communities and stakeholders.

Abstract

The purpose of this study was to determine the density of stomata and stomatal structure on Mango leaves in each ring of the cement factory area. The research is descriptive analysis. Sampling was done through a random survey in the Indonesian cement industry Tuban factory which was divided into 3 rings, namely Ring 1 Ring 2 and Ring 3. The parameters observed were stomatal density and damage. The results showed that the density of stomata in Ring 1 showed a percentage of 0.162 which showed a low density while Ring 2 was 371, 91 which showed a medium density and Ring 3 was 449.07 which showed a medium density. The results presented in Table 2 on the level of stomatal damage show a difference in the percentage of stomatal damage on mango leaves (Mangifera indica) located in Ring 1 and Ring 2. In stomata in Ring 1 with a greater percentage of stomatal damage, which is 34.7% compared to stomatal damage to mango leaves located in Ring 2 by 20.7% and Ring 3 by 11%. The conclusion of this study shows that the density and damage to the stomata of mango leaves (Mangifera indica) can be influenced by the concentration of pollutants. the level of density and stomatal damage in the Semen Indonesia Tuban area shows that the closer to the factory area the higher the level of air pollution which causes the nearest area to have high stomatal damage and high stomatal density.
