Fish farming using the biofloc system is a technological innovation capable of increasing efficiency, production results, and the sustainability of fisheries business at the village level. This study aims to determine the development of fish farming businesses using the biofloc system in increasing family income in Sembuluh village. Then, it aims to understand the impact of using the biofloc system in increasing family income and to understand the Islamic economic perspective on the utilization of the biofloc system in increasing family income. The method used is a qualitative or field research approach with purposive sampling techniques to collect data from 5 fish farmers who implement the biofloc system. Data were collected through in-depth interviews, observation, and documentation, then analyzed descriptively. The research results show that fish farming using a biofloc system is able to increase family income through increased production and feed cost efficiency. This system supports more controlled pond management, maintains water quality, and produces more stable harvests. In addition to increasing income, the implementation of the biofloc system also strengthens family economic resilience due to planned harvest cycles and group cooperation. From an Islamic economic perspective, this practice aligns with the principles of halal, honesty, justice, and social responsibility, as well as providing benefits for families and the community.

Development of a Canva-Based Informatics E-book on ICT Material for Grade X at SMA Negeri 5 Samarinda. This research aims to determine the feasibility of a product in the form of an E-book as a learning medium and to assess the response toward the Canva-based Informatics E-book for Grade X students at SMA Negeri 5 Samarinda. This study employs a Research and Development (R&D) method with the PPE model, which consists of three stages: Planning, Production, and Evaluation. The research subjects involved 35 students from Grade X (I) at SMA Negeri 5 Samarinda, along with 3 media experts and 1 material expert. The research object is the Canva-based Informatics E-book on ICT material. The results showed that the development of the Canva-based E-book, as evaluated by 3 media expert validators, obtained a percentage score of 92.19%, which falls into the “Highly Feasible” category. The Evaluation conducted by 1 material expert achieved a percentage score of 100%, also in the “Highly Feasible” category. Furthermore, students’ responses to the product were measured and obtained an average percentage score of 82.57%, which falls into the “Very Interesting” category. Thus, the development of the Canva-based E-book on ICT material for Grade X at SMA Negeri 5 Samarinda, developed using the PPE model, is declared highly feasible based on media and material expert validation and very interesting based on students’ responses.

  This paper reviews the challenges encountered by second language learners in the  acquisition  and  utilization  of  collocations,  which  are  crucial aspects of proficient language use. Collocations refer to the habitual pairing or grouping of words  that  occur  together  frequently  in  natural  language.  The  research synthesizes findings from various studies conducted in the field, highlighting common difficulties experienced by learners across different proficiency levels and linguistic backgrounds. Key factors contributing to these challenges include differences  in  first  language  structures,  inadequate  exposure  to  authentic language use, limited awareness of collocational patterns, and difficulties in achieving  native-like  fluency.  Additionally,  pedagogical  implications  and effective  instructional  strategies  for  enhancing  collocational competence are discussed,  is to inform language instructors and curriculum developers in building more targeted and effective language learning materials and activities.This  research  is  divided  into  three  sections;  section  one  presents  the preliminaries   of   the   study.   Section   two   explains   the   meaning,   types, characteristics, and importance of the study. Section three will apply a test of collocation on the 4th stage of the college to know their weakness points in collocation. Finally, the conclusion is the research.
