Abstract

The study of mophology, morphometry and alometry of Uca perplexa, one of fiddler crabs that dominated at mangrove vegetation in Pulau Baii of Bengkulu have been conducted. We measured morphometric characters including body weight and sizes of carapace, abdomen, chelae, frontal, eyebrow and eye stalk. The result showed Uca perplexa live at sandy mud substrate and made burrow around mangrove roots. Uca perplexa have back carapace with some horizontal white strips. Carapace was acute and straight at anteriolateral part and rounded at dorsolateral. Their foot color usually brown although some of them were grey, were also found. The male (2.4±0.96 g) has higher of body weight than female (0.77±0.23 g) caused by dimorphism of chelae in male. Carapace width of male and female were 14.74±4.42 mm and 10.42±3.24 mm, respectively. As for abdomen width of male was 5.16±1.61 mm and of female was 6.58±1.38 mm. The length of major chelae was 44.66±9.22 mm as minor chelae was 10.50±0.49 mm. The frontal length of male was 3.44± 0.44 mm as for female was 2.83±0.69 mm. The eyebrows were narrow with eye stalks length for male and female were 6.50±2.46 and 4.20±0.92, respectively. Alometric analysis showed that Uca perplexa either male or female has growth pattern with negative alometry (b<3). It suggest the increase of body weight in Uca perplexa is slower than the increase of size of its carapace, abdomen and chelae. Keywords : Uca perplexa, fiddler carb, morphometry, alometry, bengkulu

Abstract

Fiddler crabs (Uca spp.) are distributed widely in tropical and subtropical areas in the world. They live in the sandy and muddy bay habitats of intertidal zone. This study aimed to find species abundance, microhabitat and population density of fiddler crabs in mangrove conservation area of Pantai Panjang, Bengkulu.  The sampling was conducted for three months started from December 2013 to February 2014. Sampling locations were decided purposively on the area consist of four microhabitats, i.e. sandy, muddy, muddy around decay plant roots and around mangrove roots. Samples of Uca were collected from 1x1 m of sixty quadrants.   The results found seven species of fiddler crabs i.e. U. perplexa, U. lactea, U. jocelynae, U. forcipata, U. triangularis, U. rosea, and U. dussumieri. They were distributed at four microhabitats. The microhabitats of U. perplexa, U. lactea, U. jocelynae, U. forcipata, U. triangularis, U. rosea, and U. dussumieri were around mangrove roots and sandy, around mangrove roots, muddy, muddy, muddy around decay plants, muddy and sandy areas, respectively. Among those species, U. perplexa was the most abundant population whereas U. dussumieri was the less one. Popolation density of fiddler crabs were U. perplexa  5.48  ind/m2, U. lactea 4.25 ind/m2, U. jocelynae , 1.47 ind/m2, U. forcipata 0.28 ind/m2,  U.triangularis 0.18 ind/m2,  U. rosea 2.17 ind/m2 and U. dussumieri 0.12 ind/m2.Key words: Mangrove, microhabitat, population, Uca spp.

Abstract

Possessing and developing metacognitive abilities are an essential part of the learning process. This study is a class action research on the use of critical analysis to identify its influence on students’ metacognitive abilities and critical thinking skills as well as to discover the relationship between metacognitive abilities and critical thinking skills. The sample of this study is 76 students from 217 students taking cell biology and non-vascular plants subject during the fall semester. It is a descriptive quantitative study with critical analysis assignments. Critical analysis rubric is used to collect the data of students’ critical analysis and the essay test to measure students’ critical thinking and metacognitive ability. The data of metacognitive ability and critical thinking were analyzed using regression test. The result showed there was a positive influence of the use of critical analysis to the student metacognitive abilities and critical thinking skills. The results of a simple correlation analysis of metacognitive abilities and critical thinking skills show the means value (r) of 0.904, which means that there is a strong positive relationship between the two components. The higher the student’ metacognitive skills, the higher their critical thinking skill will be.

Abstract

Perilaku  koruptif aparatur peyeleggara Negara di Indonesia saat ini sudah sampai pada taraf yang sangat kronis,praktek korupsi terjadi di hampir semua lingkungan birokrasi milik pemerintah. Isebagai konsekuensinya,praktek memiliki implikasi yang sangat destruktif pada hampir seluruh sendi kehidupan. Korupsi telah menghancurkan sistem perekonomian, sistem demokrasi, sistem politik, sistem hukum, sistem pemerintahan, dan tatanan sosial kemasyarakatan di negeri ini. Dilain pihak upaya pemberantasan korupsi yang telah dilakukan selama ini belum menunjukkan hasil yang optimal.untuk meminimalisir potensi korupsi yang terjadi,peran semua komponen bangsa sangat diperlukan terutama generasi muda kampus yang merupakan harapan masyarakat untuk memerangi korupsi,olehnya itu upaya penanaman nilai-nilai anti korupsi dikalangan kampus sudah saatnya untuk digalakkan,metode mungkin sangat serhana yakni dengan mengintegrasikan pendidikan anti korupsi dalam desain kurikulum di perguruan tinggi tersebutPenelitian ini menggunakan pendekatan tipe penelitian kualitatif deskriptif yang menggunakan konten kajian yang terdapat dalam berbagai literature sebagai basis data primernya.Metode yang digunakan dalam pengumpulan data yakni melalui studi kepustakaan dengan cara melakukan infentarisasi terhadap seluruh sumber literatur yang digunakan kemudian diferifikasi secara cermat guna memastikan  tingkat relevansi materi yang dikumpulkan dengan objek yang menjadi fokus kajian dalam penelitianFakta yang ditemukan dalam penelitian menunjukan belum optimalnya implementasi pendidkan karakter yang berbasis pada penguatan sikap anti korupsi bagi mahasiswa di perguruan tinggi meskipun gagasan kearah tersebut telah dimunculkan pada tahun 2012 bahkan produk hukum dan standar operasional prosedurnya pelaksanaannya telah diterbitkan oleh pemerintah.rekomendasi sederhana dalam penelitian ini adalah perlu dioptimalkan pendidkan karakter di perguruan tinggi untuk menyiapkan generasi muda yang anti korupsi.Kata Kunci: karakter anti korupsi mahasiswa

Abstract

The implementation of innovative learning and lesson study (LS) are potential to improve student thinking skills and activeness differently and mostly implemented separately. This study aimed to explore and compare the student critical and creative thinking skills as well as student activeness in the inquiry and cooperative models combined with LS-based learning practice. This was a descriptive quantitative study that was conducted at Islamic Senior High School 1 of Bengkulu.  The sample was two classes consisted of 33 and 32 students each that conducted LS-inquiry and LS-cooperative learning. The essay test delivered to measure critical and creative thinking skills and observation sheet to measure student activeness. The data were analyzed by t-test to compare critical and creative thinking skills as well as the student activeness between the LS-inquiry and LS-cooperative classes. The result showed that LS-inquiry learning improved the student critical and creative thinking skills that significantly higher than LS-cooperative learning. The student activeness improved gradually as LS cycles during learning processes in either inquiry or cooperative learning, but no significant difference between these two learning models. It showed that inquiry learning plays a dominant influence in critical and creative thinking skills improvement, whereas LS in student activeness improvement otherwise.
