Organic waste that accumulates often disturbs the comfort and causes disease. The waste management system at the Medan Johor Market is still not good because there are no adequate trash cans, organic waste and non-organic waste are not separated, waste disposal at the TPA uses an open dumping system and no reprocessing has been carried out. The purpose of this community service activity is to empower the community through increased participation in waste management using the "MUSE" (Let's Turn Waste into Eco-enzyme) method". This activity was carried out in the form of socialization and direct training to 18 participants of the Karang Taruna District of Medan Johor in the Suka Maju Village Hall. The resource person explained the material using lecture and discussion methods, and then participants directly practiced making Eco-enzymes. Based on the results of the pretest and posttest analysis using the Paired Sample T-Test test, it was obtained that p-value=0.001 and the average knowledge score of 12.78 (pretest) increased to 16.22 (posttest) so that there was an increase in participants' knowledge about the meaning, manufacturing method, benefits of Eco enzymes and is able to process organic waste, especially vegetable and fruit waste into useful products. ABSTRAK Sampah organik yang menumpuk sering kali mengganggu kenyamanan dan menyebabkan penyakit. Sistem pengelolaan sampah di Pasar Medan Johor masih kurang baik karena belum tersedianya tempat sampah yang memadai, sampah organik dan sampah non organik tidak dipisah, pembuangan sampah pada TPA menggunakan sistem open dumping dan belum ada pengolahan kembali yang dilakukan. Tujuan dari kegiatan pengabdian masyarakat ini adalah memberdayakan masyarakat melalui peningkatan partisipasi dalam pengelolaan sampah dengan metode “MUSE” (Mari Ubah Sampah menjadi Eco-enzyme)”. Kegiatan ini dilakukan dalam bentuk sosialisasi dan pelatihan secara langsung kepada 18 peserta Karang Taruna Kecamatan Medan Johor di Aula Kelurahan Suka Maju. Narasumber menjelaskan materi dengan metode ceramah dan diskusi, serta kemudian peserta secara langsung mempraktikkan pembuatan Eco-enzyme. Berdasarkan hasil analisis pretest dan posttest menggunakan uji Paired Sample T-Test diperoleh p-value=0.001 dan rata-rata skor pengetahuan sebesar 12.78 (pretest) meningkat menjadi 16.22 (postest) sehingga terdapat peningkatan pengetahuan peserta mengenai pengertian, cara pembuatan, manfaat Eco-enzyme dan mampu mengolah sampah organik, terutama limbah sayur dan buah menjadi sebuah produk yang bermanfaat.
Every day was produced dry organic waste from Ahmad Yani Park Medan City accumulates in the Tanjung Marelan Landfills. The average waste generation reaches 0.797 m3/day. Continuous accumulation of dry organic waste can endanger the environment and public health. The purpose of the study was to examine how effective composting is as a method of managing dry organic waste in a city park. This research is quasi-experimental, research object was 5 kg of dry organic waste, four repetitions with three composting methods, namely Barkley, Composting Bag, and Takakura. The research location is Taman Ahmad Yani, Medan City. The study used univariate analysis and bivariate analysis with ANOVA one-way test and Bonferroni Test. Based on the results of the study, the composting time for dry organic waste in the three composting methods applied lasted 19-25 days. The results of the study, the composting time for dry organic waste is 19-25 days. The compost maturity characteristics same for each composting method, namely blackish brown in color, earthy smell and texture, pH 7,0-7,2, and temperature <30oC according to SNI Compost Quality Standard: 19-7030-2004. Based on the results of the ANOVA test p-value=0,010 and Bonferroni Test, showed that there was a significant difference in the decrease the volume of dry organic waste in each treatment after composting. The reduction of dry organic waste reached 67% -75.75%. The application of the composting method is an effective solution as a dry organic waste management method to reduce the accumulation of dry organic waste in landfills.
Bogak Village is a coastal village with a waste problem that can contribute to climate change. Instilling waste management knowledge needs to be done with the appropriate method. The purpose of the activity was to apply the Atteropoly game as an early education means regarding waste management for elementary school-age children in efforts to mitigate and adapt to climate change in Bogak Village. The stages were planning and preparation (gathering information on partner problems and compiling educational game instruments), implementation of service activities, and monitoring evaluation. Educational activities through the Atteropoly game were directly carried out on July 6, 2022 to 30 participants of elementary school-age children and two teachers from the Rumah Qur’an Miftahul Jannah. Measuring the success of Atteropoly media used pre-test and post-test, it was found that there was an increase in participants’ knowledge and the average score of 38,33 (pre-test) to 53,00 (post-test). It can be concluded the Atteropoly game increases the elementary school-aged children’s knowledge in Bogak Village. The community service team also gave a set of Atteropoly game tools and segregated trash bins to the village. It is hoped that the Atteropoly game tool can be used to educate the public, especially elementary school-age children in Bogak Village.
<p><em>Health issues are a concern of the current government. Health issues are in line with the economic development that the government is aggressively prioritizing.</em> <em>This economic improvement certainly requires a variety of supporting infrastructure. One of them is road infrastructure. Adequate road infrastructure will certainly increase traffic activity.</em><em> </em><em>Traffic activity is one of the sources of heavy metal pollution in soil.</em><em> T</em><em>he contents of motor vehicle emission gases is lead.</em><em> Lead (Pb) is one of the metal elements that can cause poisoning in humans. This research is important to determine the concentration of soil which is an area of agricultural land that is overgrown with rice. </em><em>T</em><em>his research was conducted to investigate lead concentration in roadside farmland soils according to roadside distance in the street of Lubuk Pakam – Medan km 32.

The study found that the consentration of lead in the soil was in the range of 2.33-11.40. There is no correlation of lead concentration in soil with distance from highway with r =0.093 and p=0,762.

This research investigated the relationship between basic sanitation and diarrhea among under-five children and its spatial distribution in the Pagurawan Health, Batu Bara Regency. The research employed a cross-sectional observational analytical design. The population was all mothers who have under-five children as many as 2310 population then determining the sample size using the Lemeshow formula with a total of 105. The samples were taken by purposive sampling selected by proportional from 9 rural. Data analysis used the is-square test for bivariate analysis and the overlay technique for spatial analysis. The technique performed for spatial is the overlay technique. The research revealed a relationship between the incidence of diarrhea in under-five children and water supply (p=0.034), while latrines (p=0.191), waste management (p=1.000), and wastewater disposal (p=0.825) were not. Spatial results found that the highest cases of diarrhea were in Pematang Nibung Village with a vulnerability status. Based on this research, water supply is related to the incidence of diarrhea among under-five children. Meanwhile, the latrines, waste management, and wastewater disposal are not related to the incidence of diarrhea among under-five children in the Pagurawan Community Health Center with a vulnerability status in Pematang Nibung Village.</em></p><p><em> </em></p><p><em> </em></p></td></tr></tbody></table></div><strong><em>Keywords: Diarrhea, Sanitation, Under-five children</em></strong>
