Soil plays an important role for all living things, where soil is a source of livelihood. It acts as a planting medium, a water reservoir, and a place for us to do activities. All of these activities are carried out on the land (Natasha Hutabarat et al., n.d.). In the community itself, land ownership is always a problem that is often encountered, whether it is the problem of unfixed land boundaries, land tenure, and land grabbing. The National Land Agency (BPN) as the institution that organizes land registration has a Complete Systematic Land Registration (PTSL) program that makes it easier for the community to register land so as to avoid land conflicts. In order to accelerate land registration, PTSL in Samarinda City this time uses media or tools to take measurements using the photogrammetric method, namely the Unmanned Aerial Vehicle (UAV) to obtain aerial images or the latest images. In its implementation, the community is asked to install boundary signs that have been delivered or socialized by BPN employees. So that the boundaries of the land plot can be seen from the UAV and visible from aerial images

The conversion of agricultural land in large urban areas like Jakarta has the potential to threaten food security, therefore a breakthrough in the form of an efficient urban farming model is needed. This research aims to formulate a conceptual model of an automatic irrigation system integrated with a greenhouse or greenhouse that utilizes rain water harvesting as a solution for changing the function of agricultural land in urban areas. The research method uses a literature study by examining references from 12 scientific journals and 3 textbooks related to the topic of agricultural land conversion, agricultural irrigation systems, rainwater harvesting, and the greenhouse concept. The results of the conceptual model formulation show that rainwater collected in an underground reservoir can be utilized optimally and sustainably through an automatic irrigation system to supply the water needs of agricultural land in a greenhouse on the roof of a building. This model has the potential to be a solution for changing the function of agricultural land in urban areas while supporting food security. Further studies are needed regarding specific soil moisture for various types of plants as well as direct model testing.

Of course, a soccer field needs water and the fertility of the field soil so that the grass can grow. The development of science and technology currently has a big influence on getting work done. A pump is a tool used to move liquids (fluids) from one place to another through pipes (channels) by adding energy to the fluid being moved and continuing continuously. Currently, many water pumps still use the manual method, namely using a switch or even just using a plug. Grass will also live if the soil has appropriate humidity, if the soil moisture level is low, the grass will die if there is excess moisture and it will not be able to grow. This problem certainly requires a solution that can help monitor soil moisture as well as control water pumps. By utilizing NodeMCU ESP8266 microcontroller technology as the control center, the YL-69 sensor measures soil moisture values ​​and also relays as a replacement for manual switches. To control pump conditions via Blynk.

Soil pH value either with KCl solution or with H2O are two important indicators needed to describe soil acidity. This study aims to determine the distribution of soil pH values in smallholder rubber plantations with different land topography classes in Pelepat Ilir Subdistrict, Bungo Regency, Jambi Province. The study used a survey method with a toposequence concept approach at a semi-detailed level, where observation points were made based on the upper tread polypedon, middle tread polypedon, and lower tread polypedon at each level of percent slope 15-24%, 8-15%, and 3-8%, and flat tread polypedon at a percent slope of 0-3%. Ten composite soils were taken from a mixture of 3 individual soil samples at each polypedon using a soil drill at a depth of 0-30 cm from the soil surface. Soil pH value analysis was conducted in the laboratory on each composite. The results showed that the pH value of the soil with 1:2 H2O solution was very acidic, and acidic for 1:2.5 KCl solution. The distribution of soil pH values showed that the lower slope had a higher pH value than the middle slope, and the upper slope had the lowest pH. Soil pH values decreased as the slope increased, and soils with flat topography were considered more fertile than those with high slopes. This result can be a recommendation in determining liming and fertilization doses, where higher doses are required for high slope soils than flat soils for optimum agricultural yields.

Resistivity or resistivity of the soil. Earth is assumed to be a sphere that is isotropically homogeneous. With this assumption, the measured resistivity is the true resistivity and is independent of the electrode spacing. But in reality the earth consists of different layers so that the measured potential is the effect of these layers. Then the measured resistivity value is not just a single layer resistivity value, but several layers, this is especially true for wide electrode spacing.

The application of organic farming has potential in the agricultural sector. There is a lot of empty land, adequate water sources, good soil conditions. However, it can be seen from the results of the survey we conducted that there is a lack of concern for the surrounding community and inadequate support by good management with human resources even though there is great potential in the area. So we, PKM, act as a driving force, providing understanding to the community regarding the potential that exists in the area.

Farming on peatland is a complex task due to the low soil fertility and acidic soil pH. Careful and sustainable management is crucial for peatland agriculture. To address soil acidity in peatland, natural phosphate fertilizers or lime compounds like agricultural lime or dolomite can be used. These help neutralize H+ and Al3+ ions in the soil. Eggshells have the potential as an alternative to lime (dolomite) to raise pH. Eggshells also contain about 0.3% phosphorus and microelements (magnesium, sodium, potassium, zinc, manganese, and copper) at 0.3%. The activity took place at the Teluk Latak Village Office Hall, Bengkalis Subdistrict, Bengkalis Regency, on Wednesday, August 16, 2023. The materials used in making eggshell lime fertilizer are eggshells and soil. The tools used in this practice include a blender, a spoon, and polybags. The women of the Teluk Latak Village PKK (Family Welfare Movement) responded positively to the socialization of the use of unproductive land and peat soil as a planting medium. They showed enthusiasm and actively participated in sustainable agriculture training. In conclusion, eggshells are an alternative choice as a readily available natural phosphate fertilizer from household waste. Sustainable management is essential for the success of peatland cultivation, along with the establishment of an eggshell waste bank to convert eggshells into natural phosphorus fertilizer that can help neutralize H+ and Al3+ ions in the soil.

The purpose of this activity is so that the environment of Batu Bersurat Village, XIII Koto Kampar District, Kampar Regency can become a clean and uncontaminated environment from cow dung. Cow dung can be processed into compost. Compost is an organic fertilizer made from animal waste that has undergone a fermentation process. The advantage of this compost is that it is environmentally friendly, can increase the income of farmers, and can increase soil fertility by repairing physical damage to the soil due to excessive use of inorganic (chemical) fertilizers. Batu Bersurat Village is an area with potential in agriculture, plantation and animal husbandry. The existence of cattle owned by the community has the potential to be used as compost which can be used for agriculture as well as for the fertility of plantation crops. However, the lack of knowledge of residents about the methods and benefits of making compost from cow manure causes cow manure to be thrown away, therefore people still use chemical fertilizers as a medium for the fertility of their plants. Therefore, a practice was held to make use of compost from cow manure in Batu Bersurat Village, District XIII Koto Kampar, Kampar Regency.

Soil Transmitted Helminths are parasitic worms found in tropical and subtropical countries that can cause helminthic infections in humans through contact with eggs, parasite larvae spread through the soil. Detection of STH infection is carried out by sedimentation and flotation methods. Garbage carriers are vulnerable to STH infection because they work directly with garbage and are in a sanitary environment that is not clean. The purpose of the study was to determine the results of STH examination on the feces of waste transport officers in Tawangsari Village, Malang Regency. Type of Descriptive Analytical research, conducted in July 2023. The sampling technique uses Total Sampling of a sample of 8 respondents.
