Determination of soil pH is one of the most important tests to diagnose plant growth problems. This study aims to find out an overview of the condition of a suitable soil pH to support plant growth, through the availability of microelements in the soil. In addition, to determine the extractor and the best shake time in determining the pH of the soil so that further handling can be carried out i…
The handling of baby diapers is a significant concern. This study aims to determine the effectiveness of infant absorption powder based coconut powder from the soil of Java, Kalimantan, and Papua. The image quality of coconut fiber absorption from these three islands provides an illustration of the differences in soil culture, the intensity of sunlight, and the type of coconut produced. This re…
In this study is an analysis of three representations in problem-solving on additional relativistic velocities. This research method is descriptive quantitative. Purposive sampling is a technique to get sampling in this research. The sample in this study are students who have studied relativistic speed on three different islands, namely Java Island, Kalimantan, and Papua. The students can be pr…
For all arbitrary set X with characteristic functions is known as fuzzy subsets. On group X, fuzzy subgroups can be formed appropriate with some axioms. In fuzzy subgroup there is sub set with some properties that known as level subgroups of fuzzy subgroup. This paper investigated the properties that exist on fuzzy subgroups. The properties associated with the image and pre-image homomorphism o…
