Assessing the Impact of PVC Pipe Diameter on Compressive Strength and Cracking in Hollow Prism Concrete
In order to enhance the utilization of concrete, it is necessary to explore the impact of PVC pipes incorporated into hollow prism concrete, focusing on their effects on compressive strength and cracking. PVC pipes are commonly employed as reinforcements within concrete structures to bolster their stability. This research delves into the consequences of varying pipe diameters and PVC pipes within hollow prism concrete. The experimental process entails utilizing concrete prisms with 100 x 100 x 300 mm³ dimensions, possessing a compressive strength of 25 MPa. Research outcomes reveal that pipe diameter directly influences compressive strength, where larger diameters are associated with reduced compressive strength. Including pipes in the concrete does not yield a substantial discrepancy in compressive strength. Concrete prisms with incorporated pipes exhibit a Columnar-type collapse, indicative of dominant compressive stress, whereas prisms without pipes undergo a Shear-type collapse, signifying a shift in stress distribution. It emphasizes the pivotal role of reinforcements like PVC pipes in upholding the structural integrity of concrete, thereby mitigating potential damage.In order to enhance the utilization of concrete, it is necessary to explore the impact of PVC pipes incorporated into hollow prism concrete, focusing on their effects on compressive strength and cracking.

Calculus Practicum is an essential component of calculus courses. Calculus practicum is beneficial for enhancing calculus academic achievement by utilizing technology to accomplish calculus learning goals. Calculus is a concept that students must acquire through theory and practice. Students, on the other hand, are divided into two primary personality types: extroverts and introverts. The study process was influenced by students' personality types. The purpose of this research aimed to investigate the effect of students' personalities on their conceptual understanding abilities. Personality surveys and conceptual understanding assessments used as research instruments. According to research findings, students' conceptual understanding in calculus practicum courses is heavily influenced by personality category when employing the peer teaching flipped classroom model. Experiments such as peer teaching flipped classrooms demonstrate that extrovert students have superior conceptual understanding skills than introvert students. Creating videos and establishing class discussions has a big impact on extroverted students. They can deepen their skills while also sharing their information and understanding with their peers

Effect of Extraction Time And GC-MS Analysis of Fresh and Dry Frangipani Flower (Plumeria rubra L.) using Ultrasonic Assisted Extraction
Frangipani flower (Plumeria rubra) is one of the plants that has a role in perfume and aromatherapy technology which have essential compounds that are the main cause of fragrant smelling flowers. Optimization of extract production needs to be done to obtain a high content of active substances. Ultrasonic assisted extraction is a widely used method for extraction of active compounds in certain products due to shorter operating times. This study aims to determine the effect of variations in extraction time 30,45,60 minutes from fresh and dry frangipani flowers using ultrasonic methods on extract yield values and chemical compositions using the GC-MS method. The results showed that the 60 minutes extraction produced the highest yield values, namely 5.11% for fresh yellow frangipani flower extract and 3.43% for dried yellow frangipani flower. The results of the chemical content study using GC-MS showed that the constituent compounds of fresh yellow frangipani flower essential oil consisted of fatty acids (6.59%), alkanoic acids (4.43%), triterpenoids (1.42%) and floral compound groups. Dry frangipani consists of alkanes (7.47%), alcohol (13.31%), fatty acids (1.00%)

Need Analysis of English Tourism: The Evidence from The Employees of Tourism Industry
The tourism sector now is seen as a promising sector to increase the nation's foreign exchange revenues. Therefore, a strategic effort such as providing special English language training for tourism employees in order to attract more tourists is needed. However, to produce a research program that can have a major impact on the participants, a needs analysis related to the desired outcomes has to be employed. This study aimed at finding and describing the needs of tourism employees for English language skills. Identification of difficulties during the interaction process in the field is also the focus of research so that it can be used as input in designing training programs. This research is quantitative research with survey research methods. A questionnaire with open and close-ended questions was given to 22 tourism employees at and around Gili Labak Island. The data were analyzed with mathematical computation to obtain the frequency, percentage, and mean scores. The results showed that the most important skills to be mastered by the tourism employee was listening skill (m= 4,5), followed by speaking (m=4,4), writing (m=4,1), and reading (m=3,9) respectively. In terms of problems faced by the tourism employee, they revealed that speaking skill was the most skill that experienced frequent errors during the interaction, then followed by listening, reading, and writing.
