Abstract

Ikan kancra (Labeobarbus douronensis) adalah ikan air tawar yang merupakan ikan spesifik lokasi dan merupakan ikan yang sudah langka terutama di perairan umum Jawa Barat. Keberadaan ikan tersebut dari tahun ke tahun semakin berkurang, oleh karena itu saat ini masyarakat tidak diperbolehkan menangkap dan mengkonsumsinya. Di perairan Waduk Dharma yang ada di Kab. Kuningan sudah tidak ditemukan lagi jenis ikan tersebut. Untuk itu dilakukan upaya pengembangbiakan yang meliputi pematangan gonad, pemijahan, pemeliharaan larva dan pembesaran di tangki atau kolam tanah. Pematangan gonad dilakukan dengan upaya perbaikan pakan, pemijahan melalui upaya manipulasi lingkungan, pemeliharaan larva dengan upaya pemberian pakan alami dan pembesaran dengan upaya pemberian larva nyamuk dan pelet berprotein 35%. Teknologi tersebut dirakit dan selanjutnya di sebarluaskan ke daerah-daerah yang memiliki ikan langka.Kata kunci: ikan kancra bodas, langka, perbenihan, penyebarluasan teknologi.

Abstract

A study using Research and Development design was conducted to produce a model of Biology hand book writing which is ecology and local oriented as an effort to increase students’ care toward environment. The background of this research is the reality which is  still going on untill now that the awareness and care of the school graduatee toward the environement safety is still low. Besides, hard science instructional at school could not affect or intervene the graduatee’s characteristics, for instance in keeping the environment awareness. Meanwhile, there are many concepts of environment which had been taught through hard science especially biology, so in the researcher’s point of view, biology subject has strategic role to prevent or mitigate the environment disaster caused by human activities. The model was validated at beach  ecosystem. The analysis of the research result includes three aspects, namely: 1) text comprehension, 2) environment care attitude, and 3) handbook readibility. Based on the result of beach ecosystem data analysis, it was found that (1) there was a significant difference between experimental class and control class in the beach ecosystem which is shown by tcalculation > ttable (7.429 > 2.00); (2) there was strong correlation between students’ comprehension and attitude which is shown by coeficient correlation (r) 0.634. While the text readability test (Cloze test) shown  the readability of beach ecosystem text is 57,57% (moderate). Therefore, it can be concluded that all of the texts in the developed book are fit and proper for SMA students of grade X. Kata kunci:  Penulisan buku ajar, orientasi ekologi dan lokal, kepedulian terhadap  lingkungan.

Abstract

Abstrak: Penelitian ini bertujuan untuk mendeskripsikan kompetensi mahasiswa menguasai dan mengaplikasikan konsep konservasi literasi biodiversitas, yaitu dengan penerapan program perkuliahan Biologi Konservasi Berbasis Kearifan Lokal (BKBKL) yang memadukan pembelajaran aktif di kelas dengan pembelajaran di lapangan. Metode yang digunakan adalah metode quasi eksperimen. Subjek penelitian adalah mahasiswa Program Studi Pendidikan Biologi, FKIP Universitas Sultan Ageng Tirtayasa pada semester Ganjil 2012/2013. Pengumpulan data dilakukan dengan tes, sedang analisis data dengan uji beda rata-rata (uji t). Hasil penelitian menunjukkan bahwa terdapat perbedaan peningkatan literasi biodiversitas mahasiswa antara kelas eksperimen dengan kelas kontrol. Hal ini dapat diartikan bahwa perkuliahan BKBKL yang dikembangkan mempengaruhi peningkatan literasi biodiversitas mahasiswa. Hal ini disebabkan perkuliahan BKBKL melibatkan kemampuan mahasiswa menginvestigasi, mengembangkan keterampilan proses biodiversitas dan kemampuan penguasaan konsep sehingga mereka mampu bertindak untuk menghargai biodiversitas. Akumulasi tindakan yang dilakukan oleh peserta didik akan membentuk karakter konservasi. Kata Kunci: literasi biodiversitas, kearifan lokal, biologi konservasi THE EFFECT OF THE CONSERVATION BIOLOGY COURSE PROGRAM BASED ON THE LOCAL WISDOM TOWARDS THE BIOLOGY TEACHER CANDIDATES’ BIODIVERSITY LITERACY CAPABILITY Absract: This study was aimed to describe the students’ competence in mastering and applying the biodiversity literacy conservation concept, that is, through the implementation of the conservation Biology course program based on local wisdom integrating the active teaching in the class and the teaching in the field. The method used is the quasi-experimental method. The subjects were students of the Biology Education Department Study Program, FKIP Sultan Ageng Tirtayasa University in the odd semester of 2012/2013. The data were collected using a test and analyzed using the t-test. The findings showed that there was a significant difference in the biodiversity literacy improvement between the experimental group and the control group. This can be concluded that the conservation Biology course based on local wisdom influences the students biodiversity literacy improvement. This is because the conservation Biology course program based on local wisdom involved students’ ability to investigate, to develop the biodiversity process skill and the students’ ability to master the concept so that they could appreciate the biodiversity. The accummulation of the actions done by the students will be able to implant their conservation character. Keyword: biodiversity literacy, local wisdom, consrvation biology

Abstract

Aluminium is known as competitive trivalent and its occurance in an acidic environment causes ionic disturbances in aquatic invertebrates and crustaceans. An investigation was conducted to determine the accumulation of aluminium in the tissue of giant fresh water prawn (M. rosenbergii de Man) exposed to acidic water  (pH 5.0) and more alkaline media (pH 6.5) contaminated by aluminium salt (0.3 mg/l of nominal concentration of Al).  A static test with regular water exchange was employed during the experiment. The first moulting was recorded in all treatments at the first week of the investigation.  Normal moulting period, i.e. 6 – 8 days after the first moulting was observed in 55% of prawns in the media with normal pH (pH 6.5).  A longer period, more than 10 days, was needed by prawn in the media at pH 6.5 with 0.3-mg/l aluminium, pH 5.0 and at pH 5.0 with 0.3 mg/l aluminiun.  The third moulting was only recorded at prawn in media at pH 6.5.  The elevated aluminium in the acidic media caused the highest mortality rate and there was no mortality recorded at normal pH.  Most of the mortality was observed before and soon after moulting. The elevation of 0.3 mg/l aluminium in the more acidic water (pH 5.0) increased the aluminium and decreased the calcium concentrations in the prawn tissue. However, the magnesium in the prawn’s tissue showed its highest consentration at pH 5.0 with 0.3-mg/l aluminium. The decrease of calcium concentration in the prawn’s tissue was always followed by the increase of concentration of aluminium significantly (P < 0.01).  This suggests that the aluminium interfers the intake of calcium from the media by the prawn.  However the magnesium intake was not affected.  As a conclusion, the elevated level of aluminium in the acidic media increased the accumulation of aluminium in the prawn’s tissue and influenced the moulting behaviour of the tested prawn by interfering the absortion of calsium and magnesium, i.e. decreasing the calcium and increasing the magnesium concentrations in the prawn tissue.
