Abstract

Kegiatan  usaha budidaya udang windu secara intensif mulai dilakukan dan peminatnya cukup tinggi.Meningkatnya usaha budidaya intensif diikuti dengan meningkatnya wabah penyakit yang ditimbulkan oleh golongan bakteri patogen Vibrio harveyi. Penelitian ini dilakukan bertujuan untuk menguji sitotoksisitas menggunkan Artemia salina untuk menghindari sifat toksik dari ekstrak C.racemosa terhadap kelangsungan larva udang windu (Penaeus monodon)..Metode yang digunakan dalam penelitian ini meliputi:dengan metode brine shrimp lethality test (BSLT) Hasil uji sitotoksisitas memperlihatkan bahwa ekstrak metanol tidak bersifat toksik terhadap nauplius Artemia salina (LC501000 ppm. Selanjtnya  metode agar padat terhadap strain bakteri patogen V. harveyi BPPBAP dengan menggunakan kisaran konsentrasi ekstrak berkelipatan 0,5 dimulai dari 2000 ppm sampai 15,625 ppm yang dibuat secara triplo. Hasilnya menunjukankan bahawa  Pada konsentrasi 2000 ppm memiliki diameter zona hambat tertinggi (19.33 ppm) sementara  terendah adalah konsentrasi 125 ppm  (diameter zona hambat sebesar 7,33 mm), di bawah konsentrasi 125 ppm tidak tampak  aktivitas antibakteri.

Abstract

Student discipline has a very important role in the learning process at school. Students who are not accustomed to discipline and are not handled by the school immediately, will develop habits in themselves so that they always commit violations of every existing rule. Efforts made by schools to discipline students are the existence of rules that are made so that these regulations can be obeyed. However, the existing rules at school are only used as a display without wanting to apply them concretely. So from this it is necessary to instill the value of discipline in schools, namely by giving light punishments so that students will not repeat the violation a second time. This research is a literature review research with a descriptive approach. The literature reviewed in this study comes from research journals. The conclusion in this study shows that the inculcation of discipline at SD Pertiwi Makassar has gone quite well, but still needs to be improved
