Crooked land is customary land managed by the village whose designation is used for the benefit of the village or the administration of the village. By and large, crooked soil is used for agriculture.  The use of crooked land as a source of village cash is not only in agriculture, but can also be through the field of tourism which is often referred to as agrotourism. The development of agrotourism by utilizing land based on local culture is expected to increase farmers' income and to reserve land resources, as well as maintain local culture and local technology (indigenous people's knowledge) which is generally in accordance with the natural conditions of the environment. In Kalisapu Village, most of the utilization of crooked land in Kalisapu village is still focused on agriculture as the main source of crooked land income. The crooked soil potential of the tourism field has not been optimally applied. To be able to develop crooked land into Agrotourism tourism, qualified and competent human resources are needed in Agrotourism tourism midwives. The training held is a collaboration between the Kalisapu Village Government, Slawi District, Central Java, and the proposing team of Dian Nuswantoro University (UDINUS) through a community service or community partnership program whose implementation is in the form of training, training and introduction to the concept of Agrotourism to support the use of crooked land in Kalisapu Village as an Agrotourism Area.

Shipbuilding industrial companies still produce a number of organic waste in the form of twigs, grass and leaves. In line with developments in the current era, organic waste that accumulates will become an issue for the environment if it is not managed properly. This activity was carried out to overcome the problem of organic waste in the shipbuilding industry, by utilizing organic waste for composting. Composting is a simple anaerobic method that can be easily carried out in the shipbuilding industry. This method turns organic waste into compost by carrying out a fermentation process. Organic waste in the form of leaves that are turned into compost can increase the nutrient content in the soil. The composting process is carried out using two different activator materials, namely using Effective Microorganisms 4 (EM 4) and Promoting Microbes (PROMI). The results of the compost research carried out have met the quality standards according to SNI 19-7030-2004. The final results of these two treatments are not too different, the pH resulting from the EM4 activator treatment is 6.9 and the pH from the PROMI activator treatment is 7. The temperature value for both does not exceed the ground water temperature, namely the final temperature of the EM4 activator treatment is 29.9oC and from PROMI activator treatment of 30oC. The observation results show that of the two activators EM4 and PROMI, the one that is more effectively used for composting is the EM4 activator because the microorganism content in EM4 has more classifications compared to the PROMI activator.    

Foundations are structural elements that play a crucial role in ensuring the stability and safety of buildings; therefore, understanding soil characteristics and stratification is a critical stage in geotechnical design. This study aims to analyze soil characteristics and stratification using Cone Penetration Test (CPT) data as a basis for determining safe and efficient foundation depth. The research method employed a quantitative–descriptive approach utilizing CPT test data obtained from two test points at the research site in Blitar City, East Java. The analyzed parameters include cone resistance (qc), sleeve friction (fs), and friction ratio (Rf), which were recorded continuously with depth in accordance with ASTM D3441-86. The results indicate that the shallow soil layer up to a depth of approximately 2.0 m is dominated by fine-grained soils with low qc values and high Rf values, making it unsuitable as a foundation bearing layer. The soil layer with the most favorable mechanical characteristics was identified at a depth of approximately 5.5–6.0 m, characterized by high and relatively stable qc values and low Rf values, indicating dense coarse-grained soil. Variations in the depth of hard soil layers between test points suggest lateral variability in subsurface conditions. These findings confirm that CPT data are effective for identifying soil stratification and providing preliminary recommendations for foundation depth in geotechnical planning.

Floods are disasters that often occur in Indonesia. Disasters caused by hydrometeorological factors always increase every year. Even though sometimes it doesn't cause many casualties, this disaster still damages infrastructure and significantly disrupts the economic stability of the community. The characteristics of floods are very diverse, floods can be caused by high rainfall without adequate soil absorption or can occur in the form of flash irrigation failures. South Kalimantan is a city known as the "City of a Thousand Rivers", which of course cannot be separated from flooding situations every rainy season. One of them is quite common in urban areas, especially the city of Banjarbaru. The dense population and the presence of rivers sometimes cause flooding, especially if the intensity of rainfall lasts long enough. Likewise, what often happens in the Kemuning Banjarbaru sub-district, floods that often come suddenly have become a normal activity for local residents. Without hesitation, there were even (9) RTs that were affected by the flash flood. Even though they are used to facing floods, especially when the rainy season arrives, residents are still advised to always be alert.

Waste management poses an inevitable challenge in human life and is often poorly handled. One type of waste causing significant issues is solid organic waste from households, which can lead to unpleasant odors and soil and water pollution due to its high organic content. However, the potential of organic waste to be converted into biogas, as an alternative energy source, can be harnessed through anaerobic processes. In this experiment, the researchers aimed to observe the effectiveness of adding additives to organic waste with varying doses. The organic content in the substrate for anaerobic microbes was represented by VS (volatile solid), with the inoculum sourced from cow dung. The experiment results indicate that adding NPK fertilizer additives with different doses increases biogas production. This suggests that the use of NPK additive can enhance the efficiency of anaerobic processes in generating biogas from organic waste.
