Abstract

Indonesia’s Fishery Industries has been developed very rapidly. This can cause negative effect such as increase in wastewater that involved highly organic substrates that will danger the environment. This effluent must be treated before flow it to environment and usually treated by biological wastewater treatment through nitrification and denitrification process simultaneously using activated sludge. This study doing denitrification process using activated sludge with KNO3 added, the treatment using different COD/NO3 ratios which are 3,04, 4,24 and 6,8, and monitoring do in HydraulicRetention Time (HRT) 4,5; 3,5; 2,5; 2,0; 1,5; 1,0; 0,75; 0,5 and 0,25 day. Results shows for increasingly MLVSS, Efficiency decreasingly COD, Efficiency decreasingly NO3 and denitrification rate for ratio COD/NO3 3,04 are 52,02%, 32,25%, 16,25% and 0,000759 mgNO3/mgVSS.day and for ratio COD/NO3 4,24 are 30,6%, 24,46%, 41,80% and 0,001 mgNO3/mgVSS.day also for ratio COD/NO3 6,8 are 44,7%, 23,88%, 15,95% dan 0,01 mgNO3/mgVSS.day. This efficiency result use for determine the biokinetic parameter. Biokinetic parameter such asa Y (yield), Ks and Knh (Monod Constant saturutated), Kd (endogenous decay) also µm results for rasio COD/NO3 3,04 are 0,212mgVSS/mgCOD, 6,76 mg/lCOD, 1,54 mg/lNO3, 0,105 day-1, dan 0,29 day-1 for rasio COD/NO3 4,24 are 0,267mgVSS/mgCOD, 16,77 mg/lCOD, 1,44 mg/lNO3, 0,024 day-1, dan 0,95 day-1 also for rasio COD/NO3 6,8 have results 0,2495mgVSS/mgCOD, 24,37 mg/lCOD, 1,58 mg/lNO3, 0,177 day-1, dan 0,89 day-1. This biokinetic parameter can be used to improved the wastewater treatment plant.

Abstract

Since the introduction of ChatGPT as artificial intelligence and its massive development over the years, it has had a huge impact on various aspects of life, and it is increasingly visible in the presence of increasingly advanced features, functions, and appearances. Its use in the field of education has not escaped the advancement of artificial intelligence. For some teachers and students, the term artificial intelligence is still very new, as is its use in the teaching and learning process. Currently, Indonesia's use of artificial intelligence faces numerous unavoidable obstacles and challenges. However, in global education, it is becoming increasingly common to use artificial intelligence in the teaching and learning process. The introduction of artificial intelligence to junior high school students is considered very appropriate because students' psychology at this level is more developed, and the learning load begins to increase compared to the elementary level. Math subjects for most students are still a scourge. In this community service, artificial intelligence is introduced to students of the exchange program class at SMP Insan Rabbany, which is related to mathematics learning, so that it can help in student learning. The results of the community service evaluation showed high student enthusiasm regarding the use of artificial intelligence, both to aid learning and for other purposes.

Abstract

Numeracy is an essential competency that supports students’ ability to reason quantitatively and solve real-life problems. However, students in Indonesia often face challenges in understanding mathematical concepts and applying them in everyday contexts. In response to this, a community service program was conducted at SMP Insan Rabbany, Tangerang Selatan, focusing on the integration of Artificial Intelligence (AI) applications such as ChatGPT and Educaplay in mathematics learning. The program aimed to improve students’ numeracy literacy and provide teachers with the capacity to utilize AI tools effectively. The activities included training sessions for teachers, and direct assistance in classroom implementation. The results showed a significant uses in students’ ability of numeracy. Moreover, teachers expressed increased confidence in incorporating AI-based methods into their lessons. This program highlights the potential of AI to enhance numeracy skills and underscores the importance of technological support and teacher training in the digital age.
