Currently, the government is increasingly building PLTMG to fulfill the electricity needs of the society. Beside for fulfill the electricity needs of the Indonesian people, PLTMG also has a negative impact on the society, especially for the community around the PLTMG in the city of Batam. So companies need to conduct studies on environmental impacts, one of which is the impact of the air produced on the surrounding area. The PLTMG industry does not use air pollution control devices, but uses a leanox combustion control system on each gas engine with a chimney outlet that emits SO2 and particulate emissions. The model simulation was carried out using Aermod view software with meteorological data from the affected locations. The results of AERMOD modeling show that the PLTMG industry will have an impact on particulate emissions in the ambient air around the activity location which will spread to the northwest, north, south and east of the activity location. The Aermod Model also shows that current conditions have resulted in dispersion with concentrations below the maximum limit stated in the 2021 Government Regulation. The addition of an emission monitoring system such as CEMS can be used to help monitor the concentration of dispersed emissions. Apart from that, emission control devices such as incinerators or combustion can also be used to reduce the concentration of the emissions used.

Cabbage (Brassica oleracea var capitate), broccoli (B. oleraceae L. var italica), carrots, and cauliflower (B. oleracea var botrytis) are the primary vegetable crops grown in Ngablak. The role of chemical fertilizers in crop enhancement cannot be avoided in the production of vegetables. Chemical fertilizers come in a variety of forms, including nitrogenous, phosphate, and potassium fertilizers. Fertilizer use not only boosts crop yield, but also modifies the physical, chemical, and biological aspects of the soil. However, the continual use of chemical fertilizers has led to a loss in soil organic matter (SOM) and a deterioration in the quality of agricultural soil. The excessive use of chemical fertilizers hardens the soil, diminishes soil fertility, pollutes the air, water, and soil, and depletes vital soil nutrients and minerals, consequently posing environmental risks. This research breakthrough is needed to reduce chemical fertilizers. Biochar, a pyrolyzed or anaerobically-grown biomass, could be used. This study examined the effects of biochar on disease suppression and yield in Brassica oleracea plants in rich soils in Magelang, Central Java. The treatment of this study was control, biochar, biochar+compost. The results of this study can be concluded that the maximum wet and dry weight of broccoli and cabbage plants was achieved in the biochar+compost treatment. Biochar and biochar+compost can enhance the nutrient content of the soil in broccoli, cauliflower, and cabbage. In addition, biochar has an effect (positive or negative influence) on disease in test plants. During June observations, the controls had the highest incidence and plant disease severity, whereas adding biochar and biochar+compost reduced disease incidence and plant disease severity. Increased potassium in conjunction with changes in the chemical characteristics i.e. increasing pH, total N, and C- organic of the soil results in the formation of resistance.

Flooding that occurs in the area around Kali Lahar is a problem that always occurs when the rainy season. This research aims to find the causes of flooding in Kali Lahar, located on Jalan Letjen Sutoyo, Malang City, by considering the hydrological conditions in the Kali Lahar subwatershed. The data used in the analysis is rain data from the Sukun, Ciliwung, and Petungsewu stations, with the same data range between 2008 and 2020. There is also spatial data such as DEMNAS and river networks. The analysis is carried out by modeling floods with synthetic unit hydrographs, which are then modeled with HEC-RAS 1D and 2D software to determine whether the river can accommodate flood discharge with a return period of 10 years. The discharge produced by Unit Hydrograph Nakayasu was 134.25 m3/s. This discharge is modeled using HECRAS and produces water levels up to 1.5 m above the banks. Increasing the depth of the channel is an alternative solution for flooding in this area. The simulation results of the new dimension show no flooding in the area around the channel. The results of this research can contribute to the planning and arrangement of existing canals in Malang City so that they can prevent or reduce flooding that occurs.

<p><em>The process of drying coffee beans often done by manually using sunlight which has its drawbacks, where coffee farmers cannot predict the weather which may rain at any time. If exposed to rain water, coffee beans that are slightly dry will become wet and moist again, which will affect the quality of the coffee beans. Therefore, in this research a literature study will be carried out, followed by the construction of an IoT-based coffee drying machine so that its condition can be monitored at any time. In the drying process, a PTC fan and heater will be used to regulate the temperature and humidity in the coffee drying machine to get better results in drying coffee. This research will also test how much temperature and humidity are optimal in the coffee drying machine, because it will also affect the drying time and the quality of the coffee produced. To determine the quality of the coffee beans and develop a coffee drying machine, researchers will collaborate with UKM Boyolali which has experience in drying coffee beans. IoT-based dying coffee machine has been made, with dimensions (80 x 47 x 115) cm, drying capacity of 30 grams, using electric fuel which is integrated with temperature and humidity sensors which function as drying temperature controllers, with measurement error calibration results of 1.2 and organoleptic tests show that the quality of the coffee produced by the tool/machine is better than the coffee produced by manual heating, where the coffee beans heated by the machine have a strong coffee aroma but do not smell burnt, the color is even, light brown in color and has a bitter taste and when crushed and dissolved there is no precipitate on the surface. The optimum temperature for the IoT-based dying coffee machine is 80ºC in 883 seconds or the equivalent of 15 minutes, which is equivalent to traditional drying by relying on sunlight for 10 days, while the optimal humidity for the IoT-based dying coffee machine is 15 %, this is in accordance with the quality standards of coffee as a result of heating.</em>         </p><p> </p><p><strong><em>Keywords</em></strong><em>: </em><em>Coffee beans</em><em>,</em><em> Drying coffee machine, IoT</em></p><p> </p><p class="Abstract" align="center"><strong>ABSTRAK  </strong></p><p class="Abstract">Pada proses pengeringan biji kopi saat ini masih sering dilakukan secara manual menggunakan sinar matahari yang memiliki kekurangan, dimana petani kopi tidak bisa memprediksi cuaca yang kemungkinan bisa terjadi hujan setiap saat.
