Published: March 2021

Abstract
The success or failure of a company is usually supported by the presence of reliable resources, especially human resources. Recruitment and placement of employees in the right position will have a significant impact on a company. Human nature and character are very diverse in their forms. DISC theory classifies personality into four types namely dominance, influence, steadiness, and compliance. The difference in the character of each type will of course affect the behavior style, how to deal with life pressures, and also how to communicate both directly and with social media. Through social media, a person can vent his feelings through the posts he uploaded. From these posts an analysis of the personality character he is possessed can be carried out. This systematic literature review is used to analyze and focus on techniques for conducting personality profiles through the use of social media. From this literature review of analysis, it can be obtained that the various personality classification methods and algorithms can provide a good level of accuracy.

Abstract
Two electron lenses are installed in Relativistic Heavy Ion
Collider (RHIC). They were used as operational head-on beam-beam
compensators in proton-proton collisions, with Gaussian transverse
electron beam profiles. One of the lenses was also used with a
hollow transverse profile to test hadron beam halo removal under
various conditions. Although presently not in the design, the lenses
may find applications in the Electron-ion Collider (EIC) for either
collimation or beam-beam mitigation.

Published: March 2021

Abstract
The FAIR heavy-ion synchrotrons SIS18 and SIS100 as part of
the new FAIR accelerator facility at GSI will be operated at the
“space charge limit” for light and heavy-ion beams. In SIS100 beam
loss due to space charge induced resonance crossing should not
exceed a few percent during the 1 s injection plateau. In order to
further increase the beam intensities beyond the FAIR reference
parameters, a new concept of (partial) space charge compensation by
pulsed electron lenses is considered. We describe the general space
charge compensation concept together with detailed simulations
results. A prototype lens for SIS18 is presently under development
and will be used to validate the concept. This new approach, aiming
for mitigating the most prominent intensity limitation, should be
applicable to many of the existing large scale proton and heavy-ion
synchrotrons world wide.

Published: March 2021

Abstract
Soil erosion is a natural phenomenon of a landscape system. However, its occurrence has become a threat to the environment and human welfare when populations and human needs increase, especially in agriculture. Erosion can lead to soil deprivation and reduction of soil fertility that resulted in the decline of agricultural productivity and loss of arable land. Complex processes of soil erosion due to detachment, transport, and deposition, strictly depend on climatic, topographic, and biotic factors. Erosion can be worsened by extreme climate, that lately overrides, as the key-geomorphological process of erosion. Therefore, this research is aimed to understand how biotic factors such as different surface coverages can affect erosion within marginal agricultural soil. This study developed a small-scale erosion simulator with erosion pans and rain simulator. Standard small size erosion pan with width x length x depth of 32 x 45 x 20 cm and slope of 10° was used to simulate the erosion processes. Two erosion pans were planted with peanut (Arachis hypogaea) and shallot (Allium cepa var. Aggregatum). Furthermore, the other two were covered by litter and bare soil. Rain simulator was installed in 3 m of height and produced approximately 160 mm/hr of rain. Runoff water and eroded soil were collected and analyzed to find the amount of soil and water losses. From this experiment, it has shown that our proposed small-scale erosion simulator effectively demonstrates erosion and water runoff. This study found that soil erosion rates among plots were highly variable associated with the type of surface coverage. Variabilities soil coverage decrease the impact of raindrop and soil detachment.

This study uses mixed media from dairy cattle biogas sludge waste and expired milk powder with different concentrations divided into 4 media treatments, 4 treatments then performed 3 repetitions to obtain 12 experimental units, the treatment is given code P0, P1, P2, P3 which has a media composition in the form of sawdust, biogas sludge, expired milk powder waste and eggshell, each treatment is distinguished in different concentrations of sludge and expired milk powder with different proportions namely P0 (0%: 0%), P1 (50%: 50%), P2 (25%: 75%) P3: (75%: 25%), P0 is used as a control because it does not use the two combination ingredients but uses bran as a source of nutrients and is a proportion commonly used by oyster mushroom farmers. Each media was then tested for its chemical content including water content, organic matter, crude fiber, C-organic, nitrogen, P-Total, and potassium. Then for the growing mycelium variable observed were the mycelium length, the percentage of growth of oyster mushroom mycelium, the first time to grow, and the time to fulfill mycelium. The data was processed using analysis of Variance-Completely Randomized Design Unidirectional and the average difference was tested using Duncan’s Multiple Range Test (DMRT). Mushroom media nutrient content test results showed that the best results were in the planting media of sludge biogas waste from dairy cattle and expired milk waste in P3 treatment (75% dairy biogas sludge: 25% of expired milk waste) was able to increase nutrient in a c-organic variable, crude fiber, C / N ratio, and potassium are 19.61%, 57.43%, 3.179%, and 0.887%. The best results of mycelium growth in this study were the planting media of dairy cattle biogas sludge waste and expired milk waste in P2 treatment (25% of dairy cattle biogas sludge: 75% of expired milk waste) which was able to produce the best growth of the average variables of the daily mycelium length, percentage of growth mycelium, first time to grow and time to fulfill mycelium is 3.73 cm, 27.42%, 4.33 days and 26.33 days. In this study, it can be concluded that the planting media from dairy cattle biogas sludge waste with the fortification of expired milk powder waste can be potentially used as an alternative media other than bran at the same time can increase the nutrient content in the mushroom media and stimulate the growth of mycelium better.
