This research analyzes the authority of local governments in ensuring aviation safety and security through the regulation of the Airport Operation Safety Zone (Kawasan Keselamatan Operasi Penerbangan/KKOP) and spatial control around airports in Indonesia. The study employs a normative juridical method by examining statutory regulations, international standards from the International Civil Aviation Organization (ICAO), as well as relevant cases in Ahmad Yani Airport Semarang, Mutiara Sis Al Jufri Airport Palu, and Supadio Airport Pontianak. The results show that the authority of local governments is strategic but not absolute; it must be harmonized with national policies and international standards. In practice, the implementation is hampered by normative and practical challenges. Normative barriers include fragmented regulations, weak regional legal instruments, and the lack of incorporation of ICAO standards into local regulations. Implementation barriers involve limited technical capacity, insufficient resources, weak supervision, and socio-economic resistance related to land use around airports. These conditions result in ineffective spatial control, which directly affects aviation safety and airport development. The study suggests strengthening local regulations through specific bylaws on KKOP that align with national and international standards, improving the technical capacity of local apparatus, integrating obstacle registry systems, and establishing compensation or relocation mechanisms for affected communities. Cross-sectoral coordination between central government, local government, airport authorities, and stakeholders is also essential to ensure consistent policy implementation. This research contributes to the development of aviation law, regional autonomy, and the improvement of public safety in Indonesia.

Uniaxial Compressive Strength is a test method to classify the strength and characterization of intact rock. Where it is important information in determining the strength and characteristics of a rock obtained by testing using the UCS tool. In this research, an alternative is made in determining the UCS value precisely and easily, namely by using the schmidt hammer test and compressive strength test. Therefore, this research aims to obtain the correlation value between the results of the compressive strength test and the schmidt hammer test on sandstone. Based on the results of observations and calculations that have been carried out, it can be concluded that the compressive strength value in the Balikpapan formation is lower than the compressive strength value in the Pulaubalang formation where the compressive strength value in the Balikpapan formation is 3.3 MPa-4.3 MPa, while the compressive strength value in the Pulaubalang formation is 4.3-5.57 MPa. The rebound number in the Balikpapan formation is lower than the rebound number in the Pulaubalang formation, where the rebound number in the Balikpapan formation is 16-17.8, while the rebound number in the Pulaubalang formation is 18-22.3. The correlation of the uniaxial compressive strength value with the rebound number of the schmidt hammer shows a positive linear correlation between the UCS value and the rebound number of the schmidt hammer, in this case it can be seen that when the uniaxial compressive strength value is higher, the rebound number of the schmidt hammer is also higher.

The uniaxial compressive strength value is one of the important parameters that is widely used in rock engineering projects in determining rock mass. The strength of rocks is greatly influenced by the water content and degree of saturation in the rock. Reduction of strength in rock is associated with an increase in water content, a slight increase in water content will cause a significant deviation in the compressive strength test value.This research is quantitative research, so to obtain accurate calculation data, testing methods are used in the form of compressive strength tests on rocks and physical properties tests in the treatment of samples of original rock, saturated rock and dry rock before testing. In this research, 2 types of rock were used, including limestone and sandstone in 2 rock formations, namely the Balikpapan formation and the Pulaubalang formation, so that the accuracy of the test result values ​​could be obtained well. Based on the results of observations and calculations that have been carried out, the water content values ​​of limestone in natural, saturated and dry conditions in the Balikpapan formation are obtained with average values ​​of 1.709%, 2.262% and 0.961% respectively. The water content of sandstone in natural, saturated and dry conditions is the Pulaubalang formation with average values ​​of 2.491%, 9.425% and 0.463% respectively. The UCS value of limestone in natural, saturated and dry conditions in the Balikpapan formation has an average value of 25.29 Mpa, 37.57 Mpa and 40.70 Mpa respectively. The UCS value of sandstone in natural, saturated and dry conditions in the Pulaubalang formation has an average value of 9,565 Mpa, 6,537 Mpa and 12,730 Mpa. It can be concluded that the correlation between uniaxial compressive strength values ​​and water content values ​​in limestone and sandstone shows a positive linear correlation, which means they have a strong relationship. The higher the compressive strength value of limestone and sandstone, the lower the water content value.
