Objectively, this study addresses several objectives, such as 1). Identifying the existing vegetation conditions and the amount of CO concentration in the study location, 2) To investigate the ability to reduce plants to absorb CO 3). To projecting the absorption capacity of vegetation by CO through air prediction models. The research location was conducted at Veteran Selatan, Makassar City, Indonesia. The survey was conducted in Makassar City, Indonesia, as well as data available in the field. The research period from January to April 2020. From the analysis of the results and discussion, the conclusions drawn from this study are: 1) The CO concentration based on the calculation results is 1.186.52 µg / m3. While the CO concentration measured in the field is 2,290.39 µg / m3, so the difference between the calculation and measurement results is 1,103, (48.2%). The number of trees as vegetation, namely 189 trees, had an enormous average volume of cover, namely 2,673.01 m3. 2). The existing plants or vegetation on exsiting location can absorb CO of 1,889.8 tons/year. 3). A balance between CO pollutants and vegetation uptake can be achieved by applying a scenario of planting vegetation for trees, shrubs, and shrubs. Modeling and simulation results show that the total CO emissions will reach 3,184.6 tons/year in the next ten years. However, by applying the planting scenario, the total CO emission in the next ten years will only reach 2,761.9 tons/year, with an average percentage reduction of 8.93%.

One of the reasons for environmental quality degradation is the behavior of the community in treating household waste. Contamination of rubbish to the environment contributes to contaminating groundwater for household consumption, which results in disease. This type of descriptive quantitative research analyzes the impact of improper waste disposal and the effect of providing waste management interventions and training on changes in household waste management practices. The study was conducted in North Sinjai-Regency, South Sulawesi Province, Indonesia, with 40 respondents who are people who live in the Lappa area. The research used a quasi-experimental design with one group pre-and post-test system. The results showed an impact due to the improper disposal of waste on diarrhea disease 10%, dengue fever 15%. The provision of interventions and training has effectively promoted changes in practices in household waste management.

Kebutuhan sabun dan deterjen meningkat sejak Pandemi COVID-19 seiring dengan peningkatan pola hidup bersih dan sehat. Hal ini juga dialami oleh UMKM Kampoeng Kuliner Makassar (KKM) yang menggunakan berbagai produk berbeda untuk membersihkan lantai, dinding, dan peralatan di area dapur dan kamar mandi, sehingga mengakibatkan tingginya biaya produk pembersih dan banyaknya kemasan plastik dari berbagai produk. Oleh karena itu, cairan pembersih serbaguna yang lebih ekonomis dan ramah lingkungan sangat dibutuhkan oleh KKM. Kombinasi Methyl Ethyl Sulfonate (MES) dan Eco Enzyme (EE) memiliki banyak keunggulan karena keduanya ramah lingkungan. MES merupakan surfaktan alami yang berasal dari limbah produksi minyak kelapa/sawit, sedangkan eco enzyme berasal dari proses fermentasi limbah kulit buah yang banyak dihasilkan di KKM. Pelatihan dilakukan dalam bentuk ceramah disertai diskusi interaktif dan praktek pembuatan cairan pembersih secara mandiri. MES-EE yang dihasilkan memiliki profil kualitas yang disukai oleh mitra KKM, terutama daya pembersih yang tinggi, mudah dibilas, dan tidak mengiritasi kulit. Penggunaan MES-EE sebagai cairan pembersih serbaguna dapat mengurangi pengeluaran bahan kimia pembersih hingga 50% di KKM.

The City of Kendari is being targeted for the development of infrastructure and the capacity of motorized vehicles which continues to increase. The construction of the Grand Mangku Bumi Residence has an impact on air pollution. The location of the Grand Mangku Bumi Residence development which is near the main road has resulted in residential conditions that are passed by heavy vehicles experiencing traffic noise that exceeds the quality standard limit of 55 dBA in accordance with noisy criteria according to KEP-48/MENLH/11/1996. This noise causes air pollution around the study site. The purpose of this study is to determine the value of noise non-empirically with a sound level meter due to material transportation activities. The method in this study is quantitative by observing environmental conditions, traffic volume, road geometric, vehicle noise, and vehicle speed. Noise data collection was carried out for 2 months, Monday-Friday representing working days and Saturday-Sunday representing holidays, from 07.00 WITA to 20.00 WITA. Measurements were made every 1 hour for 10 minutes with a Sound Level Meter Model TM-103. Noise mapping is done with the surfer application. The results of the study show that before construction there were 5 survey points that exceeded the quality standards permitted in KEP-48/MENLH/11/1996 and there were 14 points that exceeded the permitted quality standards with an average rate of increase in traffic volume of 46.5 pcu/hour during the construction of the Grand Mangku Bumi Residence. Therefore, the noise level prior to the construction of the Grand Mangku Bumi Residence was lower than during construction.Keywords : Noise Zone; Sound Level Meter; Traffic; Surfer Application.
