The Relationship

A method of measuring the carbon dioxide metabolism of aquatic organisms based on the relationship of acidity and carbon dioxide concentration in water is presented. This method is suitable for use in any high school biology laboratory possessing a modern pH meter. Experimental examples of the metabolism of a fish and an aquarium are shown, and three tables of constants are given to aid in the calculations necessary to this method. Additional experiments using the method are suggested.

HUBUNGAN PENGETAHUAN, PERSEPSI, DAN SIKAP DENGAN INTENSITAS PERILAKU MEROKOK PADA MAHASISWA AKADEMI FARMASI DAN MAKANAN (AKAFARMA) YAYASAN HARAPAN BANGSA BANDA ACEH TAHUN 2016     Aris Winandar 1.Fakultas Kesehatan Masyarakat Universitas Serambi Mekkah Banda Aceh Email korespondensi : ( [email protected])   Abstrak   Latar Belakang : Intensitas perilaku merokok juga menimbulkan dampak negatif bagi perokok pasif. Berdasarkan studi pendahuluan yang penulis lakukan di Akademi Farmasi dan Makanan (Akafarma) Yayasan Harapan Bangsa Banda Aceh tahub 2016 jumlah mahasiswa sebanyak 150 orang, sebagian mahasiswa terutama laki-laki mengkonsumsi rokok dalam kesehariannya, penyebab mahasiswa mengkonsumsi rokok karena ingin tampil gaya, alasan mereka jika merokok membuat pikaran jadi lebih tenang, selain itu sikap mahasiswa yang tidak mengetahui bahwa jika merokok membuat mereka mudah terkena penyakit, selain itu kurangnya pengetahuan tentang rokok juga merupakan salah satu penyebab mahasiswa tidak memperdulikan keesehatannya..(Tujuan) untuk mengetahui hubungan pengetahuan, persepsi, dan sikap dengan intensitas perilaku merokokpada remaja putra di Akademi Farmasi dan Makanan (Akafarma) Yayasan Harapan Bangsa Banda Aceh Tahun 2016. Metode : bersifat deskriptif analitik dengan pendekatan crossectional study.Hasil : ada hubungan yang bermakna antara pengetahuan dengan intensitas perilaku merokokdengan p value=0,000 (p<0,05), persepsi p value=0,004 (p<0,05), dan sikap dengan p value=0,002 (p<0,05) dengan intensitas perilaku merokok pada mahasiswa di Akademi Farmasi dan Makanan (Akafarma) Yayasan Harapan Bangsa Banda Aceh.Kesimpulan : Pengetahuan, Persepsi, Dan Sikap ada hubungan yang sangat bermakna dengan intensitas perilaku merokok pada mahasiswa di Akademi Farmasi dan Makanan (Akafarma) Yayasan Harapan Bangsa Banda Aceh   Kata kunci: Perilaku Merokok, remaja   Abstract   Background: The intensity of smoking behavior also has a negative impact on passive smoking. Based on preliminary study which the author did at Academy of Food and Pharmacy (Akafarma) Harapan Bangsa Foundation Banda Aceh in 2016 the number of students as many as 150 people, some students, especially men consume cigarettes in their daily life, the cause of students consuming cigarettes because they want to look stylish, their reasons if smoking makes the plateau so calm, besides the attitude of students who do not know that if smoking makes them susceptible to disease, other than that the lack of knowledge about cigarettes is also one cause the students do not care about his health ..(Goal) to know the relationship of knowledge, and attitudes with the intensity of smoking behavior in young men at the Akademi Academy of Pharmacy and Food (Akafarma) Harapan Bangsa Foundation Banda Aceh Year 2016. Method: analytical descriptive with cross-sectional approach. Result: there is a significant correlation between knowledge and intensity of smoking behavior with p value = 0,000 (p <0,05), perception p value = 0,004 (p <0,05), and attitude p value = 0,002 (p <0,05) with intensity of smoking behavior among students at Akademi Academy of Pharmacy and Food (Akafarma) Harapan Bangsa Foundation Banda Aceh. Conclusion: Knowledge, Perception, And Attitude There is a very meaningful relation with intensity of smoking behavior in students at the Akpararma Akademarma dan Food (Akafarma) Foundation of Harapan Bangsa Banda Aceh   Keywords: Smoking Behavior, adolescents
