Biomechanics is a science field that studies movement which can later be used as a reference for movement technique in sports. Volleyball has spike, block, service, and passing techniques. Basically, spike technique is started with a starting step then jumping. Variable spike step pattern (footwork) will cause different performance. This study aimed to get a step pattern in creating the best spike performance. This research was carried out by using experimental method. The research design used was one shot case study. The varied initial step patterns were A, B, C, and D patterns. The subject of this study was volleyball athletes of PGRI Banyuwangi University. The data collection was done in 5 replications for the starting step patterns. Then, the data was processed by using kinovea software to analyze spike performance. The results showed that the best power performance occurred in the A starting step pattern which was 115.717 J / dt while the minimum power performance occurred in the B starting step pattern which was 93,098 J / dt. This was due to a change in force (F) in the starting step in each step pattern. In the A and D patterns, the force (F) tended to increase while in B and C patterns, the force (F) decreased in the last step because there was a change in the direction of movement or a step deviation. Thus, the power performance decreased.

The purpose of this research was to analyze the third semester students’ problem in learning English basic sounds pronunciation. The research design was case study. The data were collected by recording the students’ pronunciation. The subject of the research were the third Semester Students of English Department at Universitas Ekasakti). The result of the research was found that Each aspirated /p/, /t/, /k/ have two allophones, [ph] and [p], [th] and [t], [kh] and [k]. Then, all instances of [ph] occured immediately before a stressed vowel. It can be said that the following rule: /p/ becomes [ph] when it occured before a stressed vowel or initial position of English words. Moreover, aspirated /p/, /t/, /k/ sounds were really pronounced in two different ways. First, when these sounds came at the beginning of the word they are always followed by a puff of breath. Second, if aspirated /p/, /t/, and /k/ occur at the end of final position of English words, it is not necessary to pronounce them by following a puff of breath. In following there is a chart of aspirated /p/, /t/, /k/ sounds at initial position of English words

This research is a case study that explores the dissemination and learnings of information which takes place in a diaspora organization in Toronto, the Kutchi Cultural Association. As a community of first-generation immigrants in Canada, the informal settings and learnings within this organization play an important role in their settlement process and build a sense of shared efficacy. The diaspora gatherings become the quintessential point of community engagement where knowledge is transferred and shared. This exploratory research discovers how information and learnings flow both within the organization as well as with mainstream institutions such as the libraries, archives, and museums. It highlights a missed opportunity for mainstream institutions of engaging such diaspora organizations that play a significant role in the sharing and gathering of information, albeit veiled and unaccounted for through official means and calls for more extensive research on the subject.

This study aims to describe the motives for tantrum behavior in child X in Jorong X, Solok Regency. This study uses a qualitative case study model. The case study model was chosen because this study focused on individual cases, namely the case of tantrum children. The location of this research was conducted in Jorong X in Solok Regency. The research informants were selected by purposive sampling technique with the consideration that the subject was chosen according to the research objectives. Based on this technique, five informants were obtained. The data collection procedure was carried out in three ways, namely open interviews, non-participant observation, and documentation. The data obtained from the collection techniques were analyzed by referring to the Miles and Huberman model which consists of four steps, namely data collection, coding, and sorting of data which are summarized in data reduction, data display, and concluding. Furthermore, guaranteeing the validity of the research data was carried out by using the triangulation technique, namely by combining three data collection methods. The results showed that tantrum behavior characterized by self-harm is a way for child X to make his wishes come true. The emergence of this behavior is supported by the response of parents who are more directing to a permissive pattern to always grant children's requests.
