Mining stage design which is a complex problem in terms of three-dimensional geometry that is always changing, then in this thesis the pit limit, mine sequence design or mining stages are in accordance with the tolerance stripping ratio recommended by the company and the production equipment to be used in order to obtain production targets the optimal. The research was conducted using software to design the final pit and block model method to calculate the volume. The results of the research that have been carried out obtained 752,930 MT of mined reserves and Over Burden (OB) volumes of 4,439,394 BCM and Stripping Ratio (SR).

4509 Background: Cabozantinib plus nivolumab (CaboNivo) improved objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) over sunitinib in a phase 3 trial for metastatic clear cell renal cell carcinoma (RCC). (Choueiri, abstract 6960, ESMO 2020) We report the results of a phase 2 trial of CaboNivo in patients (pts) with non-clear cell RCC. Methods: Pts had advanced non-clear cell RCC, 0 or 1 prior systemic therapies excluding prior immune checkpoint inhibitors, and measurable disease by RECIST. Cabo 40 mg/day plus Nivo 240 mg every 2 weeks or 480 mg every 4 weeks was given across two cohorts. Cohort 1: papillary, unclassified, or translocation associated RCC; Cohort 2: chromophobe RCC. The primary endpoint was ORR by RECIST; secondary endpoints included PFS, OS, and safety. Cohort 1 was a single stage design that met its primary endpoint and was expanded to produce more precise estimates of ORR. Cohort 2 was a Simon two-stage design that closed early for lack of efficacy. Correlative analyses by next generation sequencing were performed and to be presented. Results: A total of 40 pts were treated in Cohort 1, and 7 pts were treated in Cohort 2 (data cutoff: Jan 20, 2021). Median follow up time was 13.1 months (range 2.2 – 28.6). In Cohort 1, 26 (65%) pts were previously untreated, and 14 (35%) pts had 1 prior line: 10 (25%) received prior VEGF-targeted therapy and 8 (20%) received prior mTOR-targeted therapy. ORR for Cohort 1 was 48% (95% CI 31.5–63.9; Table). Median PFS was 12.5 months (95% CI 6.3–16.4) and median OS was 28 months (95% CI 16.3–NE). No responses were seen among 7 patients in Cohort 2 with chromophobe histology (Table). Grade 3/4 treatment emergent adverse events were consistent with that reported in the phase 3 trial; Grade 3/4 AST and ALT were 9% and 15%, respectively. Cabozantinib and nivolumab were discontinued due to toxicity in 17% and 19% of pts, respectively. Conclusions: CaboNivo had an acceptable safety profile and showed promising efficacy in metastatic non-clear cell RCC pts with papillary, unclassified, or translocation associated histologies whereas activity in patients with chromophobe RCC was limited. Clinical trial information: NCT03635892. [Table: see text]

Coal is one of the most mining commodities to date, especially to supply both national and international energy needs. Coal mining activities that are not well managed will have an impact on the occurrence of environmental damage. This research tried to utilize the multitemporal Landsat data to analyze the land damage caused by coal mining activities. The research took place at several coal mine sites in East Kalimantan Province. The method developed in this research is the method of change detection. The study tried to know the land damage caused by mining activities using NDVI (Normalized Difference Vegetation Index), NDSI (Normalized Difference Soil Index), NDWI (Normalized Difference Water Index) and GEMI (Global Environment Monitoring Index) parameter based change detection method. The results showed that coal mine area along with the damage that occurred in it can be detected from multitemporal Landsat data using NDSI value-based change detection method. The area damage due to coal mining activities  can be classified into high, moderate, and low classes based on the mean and standard deviation of NDSI changes (ΔNDSI). The results of this study are expected to be used to support government efforts and mining managers in post-mining land reclamation activities.

The estimation of thickness of trap rocks in the earthquake‐affected Koyna area is an important parameter for revealing the topography that existed before the Deccan volcanism. In the present work, a case history is presented delineating a three‐dimensional block model for the Koyna area by the spectral analysis of aeromagnetic data. The thickness in the area was found to vary from 700 to 2200 m, which correlates well with the results of other geophysical investigations.

Use of video by teachers can make learning more engaging or content easier to understand. Video shown in classrooms can be created by others and adapted by or created by the teacher. Traditionally, video created by teachers can be produced with inexpensive digital cameras and basic editing software. With a renewed commercial interest in Three-Dimensional (3D) video and with video equipment costs declining, the option now exists to have 3D video in classrooms. What is not known is the process to allow for teacher-created video that can take advantage of the 3D format. This case details how an undergraduate teacher candidate created a 3D video using existing production equipment and freely available software. The chapter examines the planning details, course design, and outcomes related to 3D video production. Suggestions to educators for integrating 3D into their schools are also included.

Both rent seeking and mining policy are two interesting discourses which have enriched the Indonesian policy studies within last two decades. One of prominent problems in this sector is formulation policy process of mining permit (IUP). The concern of mining sector is because the huge economic incentive behind mining business including coal mining. Since the economic incentive is extremely high, the rent seeking is getting higher and more competitive. The competition on rent seeking contest is developed in different policy formulation stages through the elites of business people and bureaucrats.The consequences are the objectivity on issuing the coal mining policy, including extra regulation about surveyors.  The policy formulation in this very case produces the dynamic and complex rent seeking activity among the main players. This study is aimed to reveal the case of rent seeking using surveyors on coal mining policy. Using qualitative method and non positivist approach, this case of study was one of five studies that tried to understand the social relationship among the policy actors during mining policy formulation.Findings in the study were: (i) the role of surveyors as “third person” as mediator who played prominent roles in delivering the interest and determined the data through surveyor’s report, (ii) bargaining power of the businessman to get access in penetrating the bureaucracy through bribing and lobbying, and (iii) the role of bureaucrat in manipulating regulation to accommodate their interest through extra regulation making.
