Open pit mining has a complex connection to excavation and stockpiling operations, which can potentially induce slope instability. The analysis of slope stability is crucial to prevent slope failure, which has the potential to result in major losses. The study on slope stability was performed at the low wall pit Y area of PT. Bina Sarana Sukses site MAS in Lahat Regency. This research aimed to analyze the rock mass classifications, determine the safety factor values, and provide recommendations for mitigating landslide occurrences. The techniques employed in this study include the RMR and SMR methods for assessing the susceptibility of landslides, collectively with the Morgenstern-price limit equilibrium approach for estimating the stability of the slope. Based on the analysis of the rock mass rating (RMR) and slope mass rating (SMR), Block B2 exhibits a 20% likelihood of experiencing landslides, specifically due to block joint characteristics. On the other hand, Blocks B4 and B5 show a 40% potential for landslides, primarily associated with flat or wedge-type block joints. The force produced by friction under saturated conditions is comparatively lower than that observed under dry conditions. During the final design phase in 2022, it was observed that Blocks B4 and B5 exhibit critical and dangerous safety factors when saturated. Hence, the proposal has been suggested to enhance slope stability. Further, it is recommended to monitor the geotechnical piles periodically. We hope this research results as a valuable resource for evaluating and assessing slope stability, including artificial and natural slopes.

The development of potential and community empowerment in the agricultural sector in Durian Village is very important to improve food security. This empowerment aims to enable the community to manage natural resources optimally, increase agricultural productivity, and in turn can create better economic sustainability. This empowerment also includes increasing the capacity of farmers in the use of agricultural technology, with the aim of implementing the concept of food security to form community food processing. The work program is implemented with a methodology, namely (1) making irrigation access wheels (2) socialization of food security and processing (3) the influence of gadgets on early childhood. The results obtained are the results of this socialization showing that the community is quite enthusiastic about utilizing water wheels as an alternative socialization in meeting energy and irrigation needs, with this socialization it is hoped that the community can better understand the importance of utilizing water resources wisely and sustainably through water wheel technology. In addition, in terms of food security and processing, 3 real follow-ups of food security and processing were produced, namely (1) the release of 20,000 tilapia seeds (2) the distribution and planting of 1200 chili, tomato, and cabbage seeds (3) the manufacture of cassava rengginang UMKM products. And it can be concluded from the goal of increasing economic welfare, as well as maintaining economic balance. With a good understanding, the community can use natural resources efficiently without damaging the environment.

The beach is a favorite tourist destination for the Indonesian people. As Indonesia is blessed with many beaches which attracts people to visit. Indonesians usually come to the beach in the holiday to fish, see beautiful scenery, and play around. Central Java Province in Indonesia has a beach cluster situated to the north and south of the Java Island. Jatimalang Beach is the south coast of Java which has excellent natural beauty, which is located in Purworejo Regency. This research is focused on the beach facilities and infrastructures, touristâ€™s ecotourism awareness, and environmental sustainability management of the Jatimalang Beach Purworejo. The study was carried out in November till December 2019 by using the qualitative research method. Information discovered during fieldwork are used to direct data collection. Qualitative researchers, are closely engaging with the environment being examined. This work was conducted through observations and interviews with tourist at Jatimalang Beach, as well as a literature review. The results showed that the facilities and infrastructure found in Jatimalang Beach were the presence of lifesavers, waste, parking lots, freshwater swimming pools for children, toilets, electrical facilities, and worship places. In addition, tourists are often willing to preserve nature and the sustainability of marine tourism on the Jatimalang Beach, however many of them do not understand the importance of ecotourism and need to be educated again.
