The research goal is to evaluate land suitability for geo-tourism focuses on geology and landscape. Most of the Citatah karst area is natural-based industries or mining in particular. The ecological disturbance is an impetus for decision-makers to choose new use of land to deal with the conservation issues. SMCE techniques that apply geographic information systems (GIS) and analytical hierarchy processes. The use of land is formulated based on policy and stakeholder analysis. The research benefit is the possibility to change the area from mining to a geo-tourism area. There are two important results of research in spatial analysis, namely: intensive and extensive tourism areas, and the rest is for protective or no suitable area of tourism. In conclusion, the land suitability analysis is important for tourism industry development.

Citatah karst area is located in the western margin of Bandung Basin, as the only mining area within the basin. However, the pressure from environmentalists to preserve the karst area and change the use of land to become a conservation area or geopark is very high. The study aims to define the strategy to manage karst land in urbanizing areas to support sustainable development. The method of study includes policy and stakeholder analyses. Further analysis will be based on Spatial Multi Criteria Evaluation to apply land suitability analysis to seek the possibility of the Citatah karst area as geotourism and mine tourism. Karst area is an environmental complex system. Broad research to understand human-altered karst landscapes, karst ecosystems, karst disturbance, karst hydrology and also to manage karst lands in urbanizing areas in sustainable manners are needed. The provincial government agency has a master plan to develop the Citatah karst areas like agriculture, tourism, home industry, etc. The research result will support the plan on how to develop an assessment of the geosite and mining site present in Citatah karst area using multi criteria evaluation.

Greater Bandung, the largest economic growth corridor in Indonesia after Jabodetabek, is sitting on the Bandung basin. This deep sedimentary basin is situated just 12 km south of the active Lembang fault. Gedebage is an area intended to be the new economic and business center located in the easternmost of Bandung. The research aims to identify the vulnerability of Gedebage area against seismic ground motions. The area's morphology is dominated by a flat area with 0 -8% of slope and predominantly composed of an old lake deposit. Topography, including basement morphology, sediment thickness, and physical properties, plays a great role in escalating/de-escalating seismic ground motions. A specific morphology may trap and prolong seismic shaking. Furthermore, stiffness and bedrock depth are instrumental in passing the spectral ground motions to the surface. The HVSR inversion method is applied to map subsurface conditions that successfully applied in Palu and its surrounding area. The research shows that Gedebage areas are vulnerable to the seismic hazard, referring to the shear wave velocity (Vs30) distribution and seismic hazard micro zonation maps. The discussion of the research findings is useful for future infrastructure development in the research area. The area is categorized as soft soil and medium soil classes, and it has a high vulnerability for destruction if there is an earthquake. The area should be cleared from vital infrastructures such as government buildings, schools, or hospitals.

Provinsi Kepulauan Bangka Belitung (Babel) merupakan salah satu daerah penghasil timah terbesar di Indonesia. Tujuan penelitian mengidentifikasi status dan sebaran logam berat (Pb, Cd, Cr, Zn, Mn) tanah di daerah pasca tambang di Provinsi Kepulauan Bangka Belitung. Eksperimen ini dilaksanakan melalui 3 tahapan kegiatan, yaitu: (1) Pengambilan contoh tanah, air dan tanaman di lapang, (2) Analisis kandungan logam berat pada  tanah, air dan tanaman serta karakteristik kimia tanah lainnya di laboratorium, dan (3) Penyusunan peta status dan sebaran logam berat pada tanah, air dan tanaman di Provinsi Kep. Bangka Belitung. Sebaran Logam berat Pb, Mn, Zn, dan Cr dalam tanah berdistribusi tidak normal, sedangkan logam Cd distribusi normal, dan sifat sebaran spasial logam Pb, Mn dan Zn tersebar mengelompok, sedangkan logam Cd dan Cr tersebar merata. Frekwensi terdeteksi logam Cd melampaui nilai MAC mencapai 96% tersebar di empat kabupaten). Terdapat korelasi positip sangat nyata (p<0,01) antara Pb dengan Mn dan Zn dalam tanah, dan korelasi negatip nyata (p<0,05) antara pH dengan Cr. Lahan-lahan pasca tambang timah di Pulau Bangka seluas 56.421 ha umumnya mempunyai kadar Pb tergolong sedang sampai rendah, Cd tergolong sedang, Cr sedang, Zn rendah dan Mn rendah sampai sedang. Logam berat Pb, Cd, Mn, Zn  dan Cr tanah terdeteksi di semua lokasi (n = 31), dengan konsentrasi minimum berturut-turut adalah 1,08; 0,79; 5,53; 42,01 dan 0,65 mg/kg dan maksimum masing-masing adalah 76,05; 7,39; 560,66; 457,07; dan 2,80 mg/kg. Frekwensi terdeteksi logam Pb yang konsentrasinya melebihi konsentrasi maksimum yang diijinkan (MAC) ada 2 lokasi (8%), logam Cd 24 (96%), dan logam Zn 8 lokasi (32%).

Kawasan perkotaan cekungan Bandung terletak di tengah pegunungan volkanik yang masuk ke dalam wilayah daerah aliran sungai (DAS) Citarum Hulu. Penelitian ini bertujuan menganalisis geomorfologi tektonik di kawasan perkotaan cekungan Bandung bagian selatan, yaitu sub-DAS Ciwidey dan Cisangkuy. Metode analisis geomorfologi tektonik menggunakan data citra ketinggian DEMNAS. Analisis geologi berdasarkan data dari peta geologi regional dan data lapangan. Hasil penelitian menunjukkan bahwa bagian selatan cekungan Bandung merupakan daerah tektonik aktif. Dari hasil tersebut, dapat digunakan untuk mengevaluasi penataan ruang di kawasan perkotaan cekungan Bandung, khususnya dari aspek kebencanaan.
