Kasang Pudak Village is located in Kumpeh Ulu District, directly adjacent to Jambi City. Kumpeh Ulu Subdistrict is developed quite rapidly due to the increasing economic and social activities of the urban community, which also influenced the social life of the city of Jambi. The lack of community awareness of the environment and the unavailability of waste management services and TPA (final processing facility) has an impact on environmental conditions in Kasang Pudak Village, Kumpeh Ulu District, Muaro Jambi Regency. By-products from agricultural activities and the capacity of rural community, especially women (mothers – housewives) who can be empowered, are an extraordinary combination of environmental management. Therefore, there needs to be a conjunction for the community to be more concerned on the environment. This community partnership program (PKM) offers an empowerment of the Kasang Pudak Village community through the establishment of a waste clinic community. The waste clinic is a community development forum that offers training programs, education and providing skills and assistance to residents in environmental management, especially waste. The target partners of this service are mothers - housewives who are members of the Kasang Pudak Village environmental care group. The waste clinic in this PKM provides training in the form of material exposure and skills including the introduction of environmental management, training in composting/ fertilizer making, entrepreneurship training and composting competitions. The long-term outcome of PKM is that the independence of mothers and young women in waste management not only improves the quality of the environment but also economic income. The waste clinic activities were able to increase participant’s knowledge and awareness as indicated by the sincerity of participants in waste sorting and composting. As a result of the interim monitoring, residents succeeded in producing compost from household organic waste, and used it for fertilizer plants.

Palm oil mills as raw materials for domestic industry and are the main export commodities can potentially produce solid waste that needs to be treated in order to avoid environmental pollution. The best treatment is if the waste is used as an energy source. The study was conducted to determine the energy produced from the utilization of palm shell and palm fiber solid waste carried out at PT Agro Mitra Madani, Tanjung Jabung Barat District, Jambi Province. This study aims to determine the number of shells and fibers produced and used as materials for boilers, analysis of electrical energy from solid waste of palm shells and fibers, and mass balance analysis from the burning of shells and fibers. The composition of the boiler is 25% shell and 75% fiber. The energy used by factories from shell and fiber solid waste is the amount of energy produced multiplied by the length of shift time, which is 7 hours. The plant's electricity demand is 4,900 kWh and the amount of electricity produced from the fibers and shells as boiler fuel is 8,253 kWh. Based on the calculation results, it can be seen that the excess power for 7 hours is 3,353 kWh and the amount of residue is 654 kg / shift. These results indicate that the utilization of oil palm shells and fiber into electrical energy is feasible.

Wastewater treatment is the main element in the success of a business in environmental management and monitoring, for this reason it is necessary to carry out maintenance and evaluation so that the sustainability of environmental protection continues. The crude rubber industry (crumb rubber) generally processes rubber in several stages, starting from sorting raw materials, cleaning bokars, macro mixing, pre-drying, crushing, drying and pressing, of course, this produces waste. The research method is evaluating the quality of wastewater from each treatment unit at the WWTP production of crumb rubber, as well as evaluating the WWTP units based on design criteria that are planned and described analytic descriptively. upon admission, namely COD of 12.876 mg/L, TSS of 1.112 mg/L, BOD5 of 980 mg/L, Ammonia 2.3 mg/L, Nitrogen 96 mg/L, pH 6.3. The results at the outlet are COD 19.35 mg/L, TSS 58.67 mg/L, BOD5 35.1 mg/L, Ammonia 0.2 mg/L, Nitrogen 10 mg/L, pH 7. While the WWTP unit design inefficient in terms of design criteria, this is because the residence time is calculated too quickly, therefore it is necessary to analyze the suitability of dimensions in order to meet the required design criteria.

Air pollution comes from construction activities in the development of educational infrastructure buildings because it has an impact on changes in green open space and an increase in air pollution, especially Carbon Monoxide (CO) emissions in the air. The contribution of increasing CO2 and CO emissions can be sourced from all activities of workers who use energy such as procurement of building materials, use of transportation fuels, electricity use activities, and LPG use activities. Carbon footprint is a measure of the total amount of carbon dioxide (CO2) emissions that come from activities or accumulations from daily activities. This study aims to determine the amount of carbon Monoxide (CO) and CO2 emissions as indicators of air quality at the Miftahun Najah Islamic Boarding School. Measurement of Carbon Monoxide (CO) parameters was carried out for one week with 7 samplings in the morning and samplings in the afternoon in situ. Measurements using the Lutron GCO-2008 CO meter and carbon footprint calculations using the IPCC 2006 method. The measurement results were obtained in the afternoon with a total of 9,926 mg/Nm3 and the lowest in the morning was 1,102 mg/Nm3. Air temperature in the morning to evening ranged from 29oC – 36oC. The results showed that the concentration of Carbon Monoxide in the development of Islamic boarding school buildings was still below the quality standards set according to Government Regulation No. 22 of 2021, namely10,000 μg / Nm3.
