Abstract

This research provides an understanding of why the Discovery-Inquiry learning method as a means to deliver the classification of living things. This research uses a descriptive qualitative approach, descriptive by conveying clearly what is meant by discovery-inquiry and why it is appropriate when implemented in the material of the diversity of living things. Education is a planned and conscious effort to create a learning atmosphere and learning process in which students actively develop their potential, discovery-inquiry is an option in its delivery. Discovery-inquiry is a learning process where a concept is not presented in its final form, but students must organize their own learning by finding out these concepts. Meanwhile, the classification of living things classifies living things based on certain characteristics. So, of course it is very related to the discovery-inquiry method which requires students to play a greater role than the teacher by finding and ensuring the object under study whether it is in accordance with the theory or finding something new.

Abstract

Increased fuel consumption of oil has an impact on the energy crisis. Biogasolin is an alternative fuel from vegetable oil that has the potential to overcome this problem. One of the methods used to produce biogasoline is the catalytic string method. Such methods generally use a catalyst to help speed up reactions. The use of catalysts in the cracking process is increasingly diverse. In this review article will compare the biogasoline percent value between several types of catalysts focused on zeolite and zeolite catalysts that are modified with metal, including the general picture of the arrest of the material, type and characteristics of the zeolite catalyst, operating conditions, and ways of performance of each catalyst. Zeolite catalyst which is a heterogeneous catalyst is considered to have good ability in selectivity, activity, and ease of modification so that it is very influential on the cracking results. Some zeolite catalysts modified with metals such as nimo/zeolite; Zn/HZSM-5; Cu/HZSM-5; Ni/HZSM-5; MO/HZSM-5; HZSM-5; PD/HZSM-5; PT/HZSM-5; Zn/Na-ZSM-5; Ni/ZSM-5; Ni/mnz; Co-NI/HZSM-5 and each biogasoline is obtained at 11.93%; 28.38%; 17.55%; 32-37%; 9-23%; 30.2%; 32-41%; 11.73% are reportedly able to provide performance to improve biogasoline results and certainly become a new catalyst that is useful in the scientific world

Abstract

Plastic waste is one of Indonesia’s most critical environmental challenges, comprising approximately 17% of the nation's 64 million tons of annual waste. This study explores the impact of a recycling workshop that transformed plastic waste into handicrafts, conducted at the Malang Waste Bank and involving students from Universitas Kristen Cipta Wacana Malang. Using an activity-based participatory approach, the workshop aimed to enhance students’ environmental awareness, practical recycling skills, and understanding of circular economy principles. Data were collected through observations, interviews, questionnaires, and documentation. The results showed a significant increase in students’ knowledge of the 3R concept (Reduce, Reuse, Recycle), along with improved technical skills in sorting, melting, and crafting recycled products such as bags, hats, and wallets. The workshop also encouraged environmental entrepreneurship by demonstrating that waste can be transformed into valuable and marketable items. This initiative exemplifies how community-based, hands-on learning experiences can foster sustainability values in higher education and support the Merdeka Belajar Kampus Merdeka (MBKM) policy framework.

Abstract

This study aims to increase precision in radiotherapy treatment planning by optimizing the estimated Hounsfield Unit (HU) value through calculating CT-scan data as a template. Radiotherapy is a therapy commonly used in the health sector to treat abnormal and uncontrolled growth of organism cells, such as lung cancer, brain tumors, leukemia and bone tumors. Radiotherapy utilizes gamma rays to eliminate abnormal cells through copying, taking into account appropriate radiation dose limits to minimize damage to normal tissue during the copying process. The level of absorption or radiodensity of a network can be expressed in Hounsfield Unit (HU) values. This simulation application design is supported by computer equipment with Intel i3 2 GHz processor specifications supported by 2 GB RAM (Random Access Memory), VGA (Video Graphics Adapter) 1 GB and 160GB hard disk. The device is used to determine the attenuation value (radiation absorption coefficient for each tissue) using the air attenuation value as a reference. The data processing method uses Green Foot software based on the multiplatform Java programming language. The program input is a CT-scan image with Grayscale analysis, and the output is Hounsfield values. The results of this study show that the use of CT-scan data and Hounsfield Unit (HU) calculations can increase the accuracy of radiotherapy planning. Using this technology, the radiation dose can be adjusted more effectively to the targeted area, while still minimizing the impact on surrounding healthy tissue. The integration of CT-scan and HU calculation in this study provides a strong basis for further development, with a focus on improving the precision and efficiency of radiotherapy.
