Abstract

The Continuously Variable Transmission (CVT) automatic transmission system is a power transmission component widely used in various industrial sectors such as manufacturing, paper, automotive, and electric power. The decision to use this transmission is made due to its ease of maintenance, affordability, and its ability to operate within various power and speed ranges. Key components of the CVT automatic transmission system include flat belts, pulleys, rollers, CVT springs, CVT clutch linings, and clutch clutches. Calculation analysis will be conducted to determine the maximum stress of the flat belt, identify the material of the flat belt, and calculate the lifespan of the flat belt using the IHR machine. The results of the calculation show that the tight side stress is 383.3639 N, the loose side stress is 64.867 N, and the belt material stress is 3.1 N/mm2. These optimal stress and material stress values are deemed suitable for use.

Abstract

Renewable energy is an energy source obtained from natural resources that can be naturally renewed in a relatively short time, so that its availability will not run out as long as its use is carried out sustainably. This article aims to increase the understanding of the Pinomontiga Village community regarding the importance of renewable energy in improving the quality of life and supporting the local economy. The results of the activity show that: 1) The activity of cleaning up garbage on the beach in Pinomontiga Village has succeeded in increasing public awareness of the importance of maintaining the cleanliness and sustainability of the coastal ecosystem. Collaboration between residents, students, and related parties not only cleans the beach, but also fosters a sense of collective responsibility in protecting the environment. Education about the negative impacts of garbage on marine biota and the local economy, especially the fisheries and tourism sectors, is an important aspect of this activity; 2) Socialization regarding renewable energy, such as solar, wind, and biomass energy, provides new insights for coastal communities about environmentally friendly energy solutions that can be optimized for local needs. The potential for renewable energy in coastal areas opens up new economic opportunities and reduces dependence on fossil fuels; 3) Tree planting in coastal areas not only functions as a greening effort, but also helps control erosion, protect against coastal flooding, and create a healthier ecosystem. Selecting the right tree species can support the development of local wind energy, providing ecological benefits while opening up opportunities in the renewable energy sector. The results of this study indicate that a community-based approach to the application of renewable energy has great potential to increase public awareness and participation in environmental conservation. Further studies can examine the effectiveness of various strategies for implementing renewable energy in coastal communities, including technical, economic, and social aspects. In addition, a more in-depth analysis is needed regarding policies that support the sustainable use of renewable energy at the local level.

Abstract

Tenses in English are used to convey when an event occurs or someone does something. Tenses are divided into 4 types namely present, past, future, and fast future. Tenses material provides specific guidance in making effective sentences and expressing activities in the past, present, and future. This research aims to analyze students' difficulties in learning English tenses. This research uses a qualitative approach with a case study method. Data collection was conducted through in-depth interviews and participant observation of students of constitutional law at Al-Zaytun Islamic Institute of Indonesia, in learning English tenses. The results showed that 90% of constitutional law students in the Midterm Examination on average only knew 5 tenses out of 13 tenses. This research shows that most students of constitutional law do not have a strong basic understanding of the structure and basic concepts of English grammar, especially tenses. This is due to the lack of emphasis on grammar as well as student interest. Keywords: Tenses, Students, Al-Zaytun

Abstract

The background of this research is the culture of marriage as a form of expression of life as stated in traditional ceremonial processions, especially the Sasak tribe in Lombok. The tradition of merarik has become part of a wedding ceremony for the Sasak people, which is a procession carried out by a pair of grooms and brides to conduct a wedding. The customary process is related to behavior patterns, which is a reflection of the meaning of community behavior, if it is violated, there will be disharmony in social life. In addition, pulling in essence can be interpreted as an important marriage in human life. Each custom process merarik in society Sasak-meal contained specific meaning in it. Therefore, thistradition merarik deserves to be appointed as a research subject, especially in its unique aspects, why thetradition is merarik used as a mandatory ritual to be fulfilled. Merariq is wedding rituals carried out by the Sasak people on the island of Lombok. Merariq for the people of Lombok is half of life to start a new life through the marriage process.

Abstract

Pumps are often found and needed in everyday life, both in households and industry. Cavitation is often a major problem in centrifugal pumps because it affects their performance and performance. Experimental studies on the effect of fluid mass flow rate on cavitation in centrifugal pumps were investigated and characterized. The Ebara Brand centrifugal pump type 65x50 FSS4JA installed in the Casting Machine TCU installation was used as the object of research. In the experimental study, the number of constant impeller blades of 6 pcs and a blade tilt angle of 60º was studied for variations in fluid mass flow rate determined with values ​​of 1.67 kg/s, 3.33 kg/s, 5.67 kg/s, and 7.33 kg/s. The results of the research show that the fluid mass flow rate has a cavitation value of 0.2 for variations in the fluid mass flow rate of 1.67 kg/s, 0.65 for variations in the fluid mass flow rate of 3.33 kg/s, 1.9 for variations in the flow rate fluid mass 5.67 kg/s, and 1.88 with variations in fluid mass flow rate of 7.33 kg/s. These results confirm that the higher the variation in fluid mass flow rate, the higher the cavitation level, but strangely when the variation is increased from 5.67 kg/s to 7.33 kg/s the cavitation value slowly decreases, this confirms that the variation in fluid mass flow rate 7.33 kg/s is the optimal fluid mass flow rate variation and allows it to be applied in the field.
