Abstract

This study aims to: 1) determine the condition of the land surface temperature of Ternate City. 2) Knowing the condition of green open space in Ternate City. 3) Determine the priority of green open space based on land surface temperature. The target in this research is green open space on Ternate Island, Ternate City, with an area of 98.67 km2. This type of research is a quantitative research with a descriptive approach. The method used in this study is the method of spatial analysis and land surface temperature with overlay techniques and scoring on three parameters, namely population density maps, vegetation index maps, and amenity index maps. The results showed that the high priority class had an area of 1248.58 Ha with a percentage of 12.43% and was dominated by built-up land of 10.71%, while the medium priority class had an area of 827.58 Ha with a percentage of 8.24% and was dominated by built-up land as much as 5.0601%, the development of green open space can be adjusted based on the type of land use in Ternate City.AbstrakPenelitian ini bertujuan untuk: 1) mengetahui kondisi suhu permukaan daratan Kota Ternate. 2) mengetahui kondisi ruang terbuka hijau di Kota Ternate. 3) mengetahui penentuan prioritas ruang terbuka hijau berdasarkan land surface temperature. Sasaran dalam penelitian ini adalah RTH di Pulau Ternate Kota Ternate dengan luas 98,67 km2. Jenis Penelitian ini merupakan penelitian kuantitatif dengan pendekatan deskriptif. Metode yang digunakan dalam penelitian ini adalah metode analisis spasial dan land surface temperature (LST) dengan teknik overlay dan skoring pada tiga parameter yaitu; peta kepadatan penduduk, peta indeks vegetasi, dan peta indeks kenyamanan. Hasil penelitian menunjukkan bahwa pada kelas prioritas tinggi memiliki luas 1248,58 Ha dengan Persentase 12,43% dan didominasi oleh lahan terbangun sebanyak 10,71%, sedangkan pada kelas prioritas sedang memiliki luas 827,5804 Ha dengan Persentase 8,24% dan didominasi oleh lahan terbangun sebanyak 5,06%, pengembangan RTH dapat disesusuaikan berdasarkan jenis penggunaan lahan Kota Ternate.

Abstract

Environmental issues are a major concern in today s society and students as future leaders have the potential to drive positive environmental change However observations at SMA Negeri 13 Maros revealed that students attitudes towards environmental concern have not fully developed This research explores how the school environment influences students environmental awareness and ability to engage in environmentally conscious behavior The approach used was quantitative descriptive involving 78 samples with purposive sampling techniques The results showed that the physical environment of the school had a positive and significant effect on the attitude of the students environment with a coefficient of B = 0 238 = 0 330 t = 2 823 and p = 0 006 lt; 0 05 Meanwhile the school s social environment showed that it had a positive but insignificant effect with values of B = 0 179 = 0 204 t = 1 747 and p = 0 085 gt;0 05 This shows that the physical environment of the school has a stronger influence than the social environment These findings imply that schools should prioritize the development and improvement of the physical environment by creating more green space and building sustainable infrastructure to effectively foster students environmentally caring attitudes < em>< p>

Abstract

This study aims to design an effective mine dewatering system for the South Pit mined-out area of PT Nusajaya Persadatama Mandiri, supporting re-mining activities. The methods used include hydrological analysis to determine the design rainfall using the Log Pearson Type III distribution, calculation of rainfall intensity using the Mononobe method, and estimation of runoff discharge using the rational method based on the catchment area. The results show that the design rainfall is 72.2 mm/day with a rainfall intensity of 49.9 mm/hr and a catchment area of 13.47 ha. The total inflow into the pit is 0.48 m³/s (1,726 .20 m³/hr), requiring a sump capacity of 7,250.03 m³. The pumping system is designed using a DnD LCC-M 100 pump with a capacity of 300 m³/hr, operated for 14 hours/day. The pumped water is conveyed through a 6-inch diameter HDPE pipe to a trapezoidal open channel, where it is then discharged into a Water Management Pond (WMP) with a total capacity of 11,200 m³, consisting of four compartments. The research results indicate that the designed mine drainage system is capable of effectively controlling mine water, thereby supporting safe and efficient re-mining operations.
