Pandemi covid-19 belum berakhir hingga saat ini, seluruh dunia termasuk Indonesia masih dihantui oleh virus ini. Peraturan biasa telah berubah tatanannya semenjak pand emi melanda dan hal ini juga berlaku pada dunia pendidikan. Pendidikan yang awalnya dilakukan dengan tatap muka kini dialihkan dengan belajar di rumah melalui metode daring. Pembelajaran daring juga diberlakukan pada PAUD. Anak yang biasanya bermain sambil belajar di sekolah bersama temannya kini tidak bisa dilakukan dengan bebas, interaksi anak dengan dunia luar dibatasi. Namun tanpa disadari pembatasan interaksi anak dengan dunia luar memiliki dampak bagi perkembangan sosio emosioal anak. Mulanya anak hanya merasa bosan namun jika dibiarkan berlarut akan mengakibatkan tekanan hingga depresi pada anak yang dapat mengganggu perkembangan sosio emosional anak. Dalam menanggapi permasalahan tersebut pada artikel ini peneliti akan membahas terkait perkembangan sosio emosional anak dan bagaimana cara menstimulus perkembangan sosio emosional anak dengan memanfaatkan permainan tradisional selama masa pandemic

Infertility can occur in men, characterized by the inability to make pregnancy in the partner. The causes of male infertility are multifactorial, one of which is obesity. Obesity parameter by body mass index >25 kg/m2. This study purposes of determining the relationship between obesity with body mass index measurement and male infertility. This type of research is an analytical cross-sectional study. This research was located at the Kasih Ibu General Hospital Denpasar. Purposive sampling was chosen as the sampling technique. The samples were 50 male patients aged 25-45 years who checked themselves at the Kasih Ibu General Hospital Denpasar between January and December 2020. All research data could be seen from the patient's medical records. The Pearson Chi-Square test was used to analyze the data. The results were 26 subjects (52%) with BMI >25 kg/m2 (obese) and 24 subjects (48%) with BMI <25 kg/m2 (non-obese). About 28 subjects (56%) were infertile, and 22 subjects (44%) were fertile. This study found that body mass index was significantly associated with infertility in male patients at Kasih Ibu General Hospital Denpasar. Obese men had a 2,308 higher risk of infertility than men were not obese (p = 0.002, RR = 2.308 (CI95% 1.262-4.220). The study has found that obesity may contribute to the event of male infertility. For further research should use a larger sample size to make it more accurate in population.

Analysis of Erosion Hazard Levels using Geospatial Information Systems in a watershed needs to be known so that it does not become dangerous, especially in the Maluka watershed. This study aims to determine the level of erosion hazard in the Maluka watershed using the USLE (equationUniversal Soil Loss Equation), calculate the rate of erosion and determine the level of erosion hazard using Geographic Information System (GIS). The calculation of the erosion rate in this study ranged from 36.83 tons/ha/year to 3,339.71 tons/ha/year. The type of soil with the highest erosion rate is alluvial type with Open Land Cover (OLC) on steep slopes of 3,339.71 tons/ha/year. While the type of soil with the lowest erosion rate is the type of red yellow pedsolic with Plantation Land Cover (PLC) on flat slopes of 36.83 tons/ha/year. The Erosion Hazard Level (EHL) of the Maluka watershed in this study was grouped into low, medium to high. The level of Erosion Hazard on the low criteria has an area of 3,370.44 ha, on the medium criteria it has an area of 402.92 ha, and on the high criteria it has an area of 6.00 ha. From the observed land units, it was found that EHL in the Maluka watershed was dominated by low criteria, namely plantation land cover. Meanwhile, with high EHL criteria, the total area is low, namely in open land cover.Analisa Tingkat Bahaya Erosi menggunakan Sistem Informasi Geospasial dalam suatu DAS perlu diketahui agar tidak menjadi membahayakan, khususnya di DAS Maluka.

Remote sensing utilization for plantation forests management in Java was not yet widely used, whereas the ability of remote sensing data for land cover monitoring and forest resource mapping has been developed, ranging from low resolution imagery for global areas to moderate and high resolution for small scale areas. Data availability and human resources often become obstacles in the application. The emergence of Sentinel satellite images becomes an alternative because the dataset is free access and has moderate spatial resolution and high temporal resolution. This study aims to map the growing stock volume in UGM Educational and Training Forest using Sentinel-2 imagery. Three kinds of classification method based on machine learning algorithms i.e. Random Forest, K-NN and SVM were compared for land cover classification. An NDVI algorithm was also used for mapping the spectral value distribution. Moreover, a stand age distribution which obtained from KHDTK UGM manager were also map. A stand classification map based on land cover types, NDVI value and stand age distribution was created as a basis of growing stock volume estimation. The analysis show that the growing stock volume can be estimated using these method with RMSE 177,8 m3 and MAPE 21,9 m3.

The effect of thermal insulation of the lining on the heat exchange of rotating apparatuses
Authors: Shcherbyna Valerii , Shvachko Denys 
Published: July 2022

Rotary kilns are used in many industries to process bulk raw materials. In the building materials industry, rotary kilns are widely used for heat treatment. However, the fuel utilization factor in rotary kilns is extremely low. Thus, the bulk of cement clinker is fired in furnaces, the thermal efficiency of which does not exceed 55-60%. Therefore, the task of increasing the efficiency of such units is extremely relevant. In operating furnaces, heat losses to the environment only through the furnace body reach 20-25% of the total heat of combustion. In this case, one of the main factors determining the thermal efficiency of furnace operation is the value of thermal resistance of lining.
The aim of the work is to study the evolution and temperature changes in the rotary kiln lining made of shaped refractory to reduce heat losses to the environment and improve the efficiency by increasing the thermal resistance of the lining. The increase in thermal resistance is achieved by changing the shape of the refractory by creating appropriate cells and introducing additional fibrous insulating material into them.
A mathematical model and software have been developed and numerical calculations have been carried out to determine non-stationary temperature fields in the lining with a thermal insulating element and to substantiate the choice of an appropriate thermal insulating fibrous material.
Analyzing the calculation results, it is possible to conclude about the expediency of using a lining with increased thermal resistance. The use of this technical solution makes it possible to reduce heat losses through the housing by 18-24%, to increase the amount of transferred material in the working zone by 1.5-8% due to the creation of an appropriate temperature field in the working volume, and to reduce the mass of the lining and the furnace as a whole. and increase the energy efficiency of the thermal unit.
The presence of cells with additional thermal insulation contributes to the emergence of thermal pulsations having oscillatory character and affecting the intensification of heat and mass exchange processes, which in general contributes to the performance of the thermal unit.
A significant advantage of this method is also the fact that increasing the energy efficiency of the furnace does not require additional fuel consumption, increasing the temperature or increasing the enthalpy of the combustion products.

The paper studies and analyzes the technological parameters of modern running systems of machine units and the environment for their use in accordance with modern conditions. As a result of the experiments, the dependences of the rolling resistance coefficients, adhesion and towing for wheeled propellers, caterpillar on rubber and caterpillar on steel, depending on hardness and background, were obtained. So, for power vehicles with a rubber caterpillar, the functions of these values, depending on the hardness of the soil in a layer of 0-10 cm, will be as follows: f = -0,015Т2 + 0,169Т + 0,472, µ = -0,001Т3 + 0,015Т2 - 0,078Т + 0,204, δ =0,033 ехр(7,154р) + 0,792.
The obtained data have a high approximation reliability and are used in the operation of the algorithm of the controlled system
