Abstract

This PKM activity was carried out in Paddinging Village, Sanrobone District, Takalar Regency, for four months. The main problem he faces is using conventional seed planting tools, so the process of perforating and planting corn seeds takes a very long time and uses manpower. So far, the time required for perforating and planting seeds using conventional tools, namely for an area of ​​1 ha, takes four days, even in the process of perforating and planting corn seeds using labour, so the target audience must spend a very large amount of money to pay labour wages. In addition to using conventional corn seed planting tools, the target audience also experienced difficulties procuring micro fertilisers, namely urea, NPK, and ZA fertilisers. In addition to the high price of microfertilizers due to reduced government subsidies, there are sometimes shortages in the market. The service in this village is so that the Target Audience can use Modern Corn Seed Planting Equipment and utilise calcium fertiliser to supplement their corn plants. Corn seeds efficiently have low operating costs, increasing the harvest's quality and quantity. The solution provided to achieve this goal is the procurement of a modern corn seed planting tool called the Imtagro NTCC One Output Corn Planting Tool and calcium fertiliser as an investment for the Target Audience, as well as Assistance to the Target Audience, as well as Assistance to the Target Audience on the use of these modern tools and use of calcium fertiliser on corn plants. ---  Kegiatan PKM ini dilaksanakan di Desa Paddinging Kecamatan Sanrobone Kabupaten Takalar selama empat bulan. Permasalahan utama yang dihadapinya adalah penggunaan alat penanaman bibit yang masih konvensional, sehingga dalam proses pelubangan dan penanaman bibit jagung membutuhkan waktu yang sangat lama dan menggunakan tenaga kerja. Selama ini, waktu yang dibutuhkan untuk pelubangan dan penanaman bibit dengan menggunakan alat yang masih konvensional yaitu untuk lahan seluas 1 Ha membutuhkan waktu selama 4 hari, bahkan dalam proses pelubangan dan penanaman bibit jagung menggunakan tenaga kerja sehingga Khalayak Sasaran harus mengeluarkan biaya yang sangat besar untuk membayar upah tenaga kerja. Selain penggunaan alat penanaman bibit jagung yang masih konvensional, Khalayak Sasaran juga mengalami kesulitan dalam pengadaan pupuk mikro yaitu pupuk urea, NPK, dan ZA. Selain mahalnya harga pupuk mikro tersebut karena berkurang subsidi dari pemerintah, juga kadang terjadi kelangkaan di pasaran.

Abstract

Research has been carried out on the utilization of biomass waste of coconut trunk sawdust using the pyrolysis method to produce two products simultaneously, namely charcoal and liquid smoke. In order to obtain charcoal products with optimum calorific value, it is necessary to understand the optimum pyrolysis conditions. One of the optimum conditions, namely pyrolysis temperature, was studied in this research. Pyrolysis was carried out in a simultaneous pyrolysis reactor at a flow rate of argon inert gas into the reactor of 2 liters/minute and a pyrolysis time of 2.5 hours with pyrolysis temperature variations of 350, 400, 450, and 500°C, respectively. The study showed that the optimum temperature of 400oC was obtained which gave a yield of 34% charcoal with a calorific value of 7229 kcal/kg. Compared to the calorific value of the raw material for coconut sawdust which is 4400 kcal/kg, there was an increase in the calorific value of the pyrolysis product by 64%. Based on the optimum temperature condition, liquid smoke as a by-product was also obtained with a yield of 45%. Charcoal can be used as a solid fuel or as a bioadsorbent in the treatment of liquid waste or clarification of liquid food products such as virgin coconut oil (VCO). Grade 3 liquid smoke can be used as a biopesticide, while grade 1 liquid smoke can be used as a food preservative. Given the benefits of the two pyrolysis products, both of the products from the current research have a promising market value.

Abstract

Air pollution, especially in big cities in Indonesia, has reached a very worrying level. The main sources of air pollution come from various human activities, including industry, transportation, offices, and housing. These various activities are the biggest contribution of air pollutants that are released into the free air. In this study, observations and measurements of air pollution levels were carried out in the Final Disposal Site (FDS). The absence of good waste management in Sinjai Regency has triggered the community to manage waste by means of Open Dumping, where waste is simply dumped in a landfill without any treatment. Pollutant gas originating from the landfill will produce harmful gases, including Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2) and others. This study aims to determine the concentrations of Nitrogen Dioxide (NO2) and Sulfur Dioxide (SO2) in Final Disposal Site (FDS) Tondong and in residential areas around Tondong FDS, Sinjai Regency by using the passive sampler method. The test results obtained are the NO2 value at point 1 which is 3.69 g/m3, point 2 is 5.25 g/m3, point 3 is 3.1 g/m3 and point 4 is 7.1 g/m3 with an average value The average NO2 parameter test is 4.785 g/m3. While the SO2 value at point 1 is 4.46 g/m3, point 2 is 7.34 g/m3, point 3 is 8.47 g/m3 and point 4 is 5.93 g/m3. The average value of the SO2 parameter test is 6.55 g/m3. Calculating the Air Quality Index based on the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number 27 of 2021 concerning the Environmental Quality Index, air pollution at the Tondong Landfill is worth 93.14 indicating the very good category.
