Keliki Village, Tegallalang District, Gianyar Regency, Bali Province, has a TPS3R which was initially considered less attractive by the local community because it was considered to interfere with tourism. This background encouraged the implementation of green infrastructure in the TPS3R of Keliki Village as an effort to improve the quality of the environment and the aesthetics of the area. The problems faced were the low public awareness of sustainable environmental management and the lack of skills of local craftsmen in implementing green infrastructure principles. The purpose of this activity was to rearrange the TPS3R according to green infrastructure standards, while providing training to local craftsmen so that they are able to work on infrastructure projects properly. The method used involved collaboration between the Bali State Polytechnic, the Keliki Village Government, and the Yowana Bakti Keliki BUMDES, with training in installing environmentally friendly geotextile-based paving as the main focus. The Village Government provided the facilities, infrastructure, and materials needed, while the BUMDES facilitated labor from local banjars. The results of this activity showed an increase in the skills of local craftsmen and the arrangement of the TPS3R which was more visually attractive, in accordance with the concept of green infrastructure. In conclusion, the implementation of green infrastructure in TPS3R has not only succeeded in improving environmental quality, but also changed the image of TPS3R into an environmentally friendly area and more attractive to the community and tourists.

Biogas is an environmentally friendly alternative energy source that is widely developed in society. Livestock waste is a source of biogas that is easy to obtain and the installation of digestion is easy, making biogas used by the community as an alternative to LPG. Kuncen Farm is a livestock farmer group that has a business cultivating dairy goats, fattening goats (Jawarandu Goats) and breeding Etawa goats. So far, goat manure waste is still managed conventionally, where only organic fertilizer is used for community agricultural needs and only makes up 30-50% of the total manure waste. Goat waste that is not used ends up being simply collected, producing an unpleasant odor and disturbing the environment. Based on the problems faced by Kuncen Farm and the potential of goat manure waste as a source of biogas, the application of biodigester technology on a household scale is a solution to goat manure waste as well as being a supporting facility for goat milk production at Kuncen Farm. This biodigester technology is made from PE plastic and utilizes used items around the house that can be used, such as used bottles, used stoves, motorbike tire rubber, etc. The main product in the form of biogas is used as fuel in gas stoves for goat's milk production and the by-product can be used as liquid fertilizer or organic compost which has economic value. This biogas stove can replace LPG fuel for cooking goat's milk. Furthermore, this biodigester technology can be installed on each group member.

Following the flash flood in Bahorok in 2003, concerns about potential similar disasters in the future have been on the rise among both the community and the government. However, economic demands in the vicinity of the affected area have led the community to continue utilizing the riverbanks for building purposes, particularly for nature tourism. This land use has resulted in the narrowing of the river, leading to floods and landslides. Therefore, the less skilled construction workers, who are partners in this initiative, require assistance from the proposing team to provide training in building construction, especially in landslide-prone areas. This training is expected to be a solution to address the issue. Through the exchange of ideas with the proposing team, the partners can enhance their understanding of anticipating building damages due to errors in construction methods. After the training, the community will have a guide for planning and constructing buildings in landslide-prone areas, creating a safe and comfortable environment for both the local residents and tourists visiting Bukit Lawang.

Construction prioritizes the strength of concrete without thinking about the negative impact on the environment. The cement industry is estimated to contribute 5-7% of CO2 gas emissions in the world. On the other hand, Indonesia is also faced with environmental problems caused by various industrial waste. From this problem an innovation emerged, namely ABUTA (husk ash and brick ash). The aim of this innovation is to create a concrete innovation using Abuta Waste (Rice Husk Ash, and Brick Powder). For the manufacture of economical, environmentally friendly concrete to reduce the negative impacts caused by excessive use of cement and reduce industrial waste in Indonesia. In writing this proposal the author used the experimental writing method and data collection method. The concrete innovation applied is concrete with a mixture of variations in the composition of rice husk ash powder and red brick powder of 10% of the cement composition in conventional concrete so that it is more economical and environmentally friendly. In this study, the ACI (American Concrete Institute) mix design method was used with the required design quality of 30 MPa. It is hoped that this innovation can become an environmentally friendly concrete innovation to reduce the negative impacts of excessive cement use and reduce industrial waste in Indonesia. Based on the mix design, the proportion of ash mixture (rice husk ash and brick powder) is 1:1. Meanwhile, the ratio of the amount of ash mixture to cement is 10%: 90%. The compressive strength of concrete with a 0% Abuta mix variation (7 days old) was 19.5, while the concrete innovation with a 10% Abuta mix variation (7 days old) was 15.70 Mpa. This means that the 10% mixture reduces the compressive strength value by 46.28% below the 0% abuta mixture variation. Using a mixture of 10% ash (rice husk ash and brick powder) in innovative concrete can reduce production costs by IDR. 76,700/m ³. Based on the materials obtained in this manufacture, it can be concluded that to obtain optimal compressive strength, better quality materials are needed. The application of concrete can be applied in casting work floors and non-structural construction work such as buildings that require general load power such as housing, sculpture, home interiors and others.

<p>One of the challenges faced by students from SMK is the learning atmosphere and learning system applied by PTV. This is due to the gap between the SMK curriculum and PTV. State Vocational High School (SMKN) 7 Semarang is one of the vocational schools located in the city of Semarang. SMKN 7 Semarang has 8 expertise competencies, one of which is competence in the field of civil engineering, namely Building Construction, Sanitation and Maintenance (KGSP) and Road, Irrigation, and Bridge Construction (KJIJ). Students of SMKN 7 Semarang already have a basic understanding of civil engineering, but when they enter the PTV world, they still experience difficulties in several fields. Therefore, to bridge and fill the gap from the SMK curriculum to PTV, it is necessary to introduce and train related fields of civil engineering, one of which is field testing. Semarang State Polytechnic as one of the universities has competent human resources to provide solutions to these problems. The PKM team provided introduction and training on the use of hand drill and vane shear tools used for soil testing. The hand drill is used to take disturbed and undisturbed soil samples, while the shear vane is used to determine the shear condition of the soil. After conducting the introduction and training activities, students can better understand how to use the test equipment. In addition, students also understand better in analyzing soil data obtained from testing.</p>
