Landfill activities can produce leachate water that can be infiltrated into the soil so that it can pollute the surrounding well water.. This study aims to map the distribution of leachate water to the quality of shallow groundwater around TPA. Sampling of well water owned by residents is 100-700 meters from the TPA and 2 leachate water sample points of the Sukosari TPA. The parameters of leachate water and well water analyzed include, pH, BOD, COD. The quality standard for shallow groundwater quality used is the class I quality standard of Government Regulation No.82 of 2001, while the leachate water quality standard used is the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia No P.59 / Menlhk / Setjen / Kum.1 / 7/2016. The quality of shallow groundwater around the Sukosari TPA is polluted with leachate water judging from the parameters of pH, BOD and COD. The pH parameter does not meet the quality standards, the BOD value that meets the quality standards is only 6.7,8.9. COD value that meets the quality standards is only the location of the well 7. The effect of leachate water derived from the Sukosari TPA on well water quality showed a positive correlation for the pH parameter, namely with a value coefficient of 0.911 and for the BOD and COD parameters showed a negative correlation, namely with a BOD value of -0.657 and a COD value of -0.628 and there was a significant relationship. Map data processing techniques with Kriging and IDW interpolation methods.Keywords: groundwater, shallow groundwater quality, litter, TPA.

Minyak jelantah jika dikonsumsi akan menimbulkan penyakit bagi manusia, sedangkan apabila dibuang ke lingkungan akan dapat mencemari lingkungan sekitar. Supaya minyak jelantah bisa digunakan kembali, perlu dilakukan proses penjernihan minyak jelantah dengan cara adsorpsi Salah satu faktor yang mempengaruhi besar kecilnya adsorbsi adalah luas pemukaan adsorben. Sehingga perlu dilakukan aktivasi terhadap adsorben untuk meningkatkan luas permukaan.  Penelitian ini bertujuan untuk mencari kondisi suhu dan waktu optimum dalam proses aktivasi zeolit alam secara fisik. Proses aktivasi fisik meliputi penggerusan zeolit alam menggunakan gilingan porselin dan mengayaknya supaya ukurannya sama 100 mesh. Kemudian memanaskan di dalam furnace dengan variabel suhu pemanasan ±200, 300, 400, 500 dan ±600 oC sedangkan variabel waktu pemanasan adalah 90,135,180,225 dan 270 menit, kemudian mendinginkan di dalam desikator. Setelah itu melakukan uji adsorpsi pada minyak jelantah dengan menggunakan zeolit alam yang sudah diaktivasi untuk mengetahui kondisi suhu dan waktu pemanasan aktivasi fisik yang optimal. Kondisi optimum yang diperoleh dalam penelitian ini adalah pada suhu pemanasan ±400oC dan waktu pemanasan 225 menit dengan nilai angka asam lemak bebas 0,8138% dan nilai angka penyabunan 180,589 mgKOH/gr.

Waste management according to Act No. 18 of 2008 on Waste Management is a systematic, comprehensive, and continuous covering waste reduction and handling.  However, currently most of the waste management carried out is still just collecting and transporting waste without any effort to reduce the amount of waste generation. As a result of waste management that there is no effort to reduce, the amount of waste generation will be large and only end up in the final disposal site (TPA), which affects the health of the environment around the landfill site, such as the formation of leachate, methane gas and odors. For this reason, it is necessary to make an effort to reduce the amount of waste generation, one of which can be done is by way of community-based waste management through 3R (Reduse, Reuse and Recycle). Based on these problems, it is necessary to do socialization to the community about how to manage community-based waste through the 3Rs so that people can play an active and sustainable role in waste management.

In the village of Gesikan, Subdistrict of gantiwarno, Regency of Klaten, there is a home industry in the form of mushroom cultivation. Mushroom SME in Gesikan Village was established 9 years ago and is still capable of meeting the needs of the food industry. Jamur Raya SME has several types of mushrooms that are cultivated such as oyster mushrooms, straw mushrooms, ear mushrooms, Lingzhi mushrooms and so on. Jamur Raya SMEs carry out production starting from nurseries to ready for planting. The results of these mushroom seeds are usually sold to farmers up to 1000 mushroom seeds every month. A portion of the seedling will be planted on its own and then sold according to customer needs. Mushroom Raya SMEs have a fairly high potential in production in the food industry, but there are also obstacles that are felt by these SME producers.Some of these obstacles are the lack of ability of Mushroom Raya SME to meet consumer needs caused by the limitations of production tools that are still simple/manual. The filling of planting media in the form of baglog and mixing of planting media is still done manually, so it takes a lot of time and energy to process it. In addition, there are environmental constraints, namely in the form of former planting media waste that accumulates, resulting in an unhealthy environment. Another perceived obstacle is from the marketing side which is still conventional or offline. Of course, this also needs to be supported by qualified human resources. Appropriate technology in the form of baglog filling equipment, planting media mixer & straw chopper is expected to be a solution to accelerate mushroom production in meeting consumer needs. Baglog waste treatment in improving environmental quality is also expected to provide solutions to maintain environmental health & cleanliness by using brisket maker and composter. Mushroom Raya SMEs are also expected to survive in the dynamics of the global market so that online marketing is an option to maintain this food industry. Marketing using website media is expected to be able to provide wider information in all circles of society.

The buffer zone and limited cultivation zone of the TPA Troketon are used as vegetable fields, where in these zones can be polluted by leachate containing non-essential metals (Hg, Pb, Cd, etc.). Non-essential heavy metals are toxic when consumed. Non-essential heavy metals are absorbed into plant tissues, so water for watering vegetable crops must be free from heavy metal content. However, farmers use water from wells dug around the TPA to water the vegetable crops in their fields. Based on the description above, the authors conducted research on the relationship between the distance of the dug wells and the levels of Cadmium, Lead and Mercury in the dug well water around the TPA Troketon.This study aims to determine the effect of the distance dug wells on the TPA with the metal content of Cadmium, Lead and Mercury in the dug well water which is located in a straight line with the TPA and the IPL output flow. This research was conducted by checking the levels of Cadmium, Lead and Mercury in the laboratory and then the results were compared with the distance of the well to the landfill by analysis using SPSS.The results of the analysis of the relationship between well distance and lead levels in dug well water show a negative correlation with a coefficient value of -0.565 or have a relationship but not significant and the effect of distance with lead levels is 35.6%, while Mercury metal in dug well water shows correlation with coefficient value of 0.512 or having a relationship but not significant and the effect of distance with mercury levels of 26.2%. As for the metal content of Cadmium, the tool cannot read in more detail, so a correlation analysis is not carried out. The levels of heavy metals analyzed in well water are still below the permissible threshold.
