Aplikasi Biomolekuler di Dunia Perunggasan Khususnya Itik

Artikel Aplikasi Biomolekuler di Dunia Perunggasan Khususnya Itik bertujuan untuk melakukan pendekatan biomolekuler melalui deteksi berdasarkan polimorfisme DNA. Peternak dapat menghasilkan bibit itik dengan genetik yang unggul sehingga produktivitas itik akan semakin tinggi dibanding sebelumnya. Metode yang digunakan adalah deskriptif berdasarkan referensi pustaka dari beberapa literatur yang telah dipelajari terkait aplikasi biomolekuler di dunia Perunggasan khususnya itik. Kemampuan produksi itik dipengaruhi oleh kemampuan genetik yang dimilikinya, semakin tinggi kemampuan genetik yang dimiliki semakin tinggi pula kemampuan produksi yang dihasilkan apabila didukung oleh faktor lingkungan yang optimal (sesuai dengan kebutuhan). Pendekatan biomolekuler melalui deteksi berdasarkan polimorfisme DNA memungkinkan untuk memilih itik dengan genetik unggul, karena setiap individu memiliki susunan genetik yang berbeda-beda. Metode analisis untuk mengindentifikasi keragaman genetik secara molekuler pada beberapa jenis spesies unggas dapat dilakukan dengan Randomly Amplified Polymorphic DNA (RAPD), Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP), analisis sidik jari (finger printing), minisatelit (VNTR atau Variable Number Tandem Repeat), mikrosatelit (STR atau Short Tandem Repeat) dan Analisis DNA mitokondria. Kesimpulan dari artikel ini adalah biomolekuler mempermudah peternak dalam pemeliharaan unggas khususnya itik dan efisiensi biaya dalam pemeliharaan

Case-based Reasoning (Cbr) dan Pengaruhnya terhadap Peningkatkan Kemampuan Pemecahan Masalah

Penelitian ini memfokuskan pada upaya pemecahan permasalahan mengenai rendahnya kemampuan siswa dalam memecahkan kesulitan-kesulitan ketika mempelajari materi pelajaran Bahasa Indonesia. Tujuan penelitian ini diarahkan pada upaya menjelaskan pengaruh Case-Based Reasoning (CBR) dalam pembelajaran terhadap kemampuan pemecahan masalah siswa. Metode penelitian adalah kuasi eksperimen dengan objek penelitian adalah siswa MA di salah satu kabupaten di Jawa Barat, di mana pembelajaran yang digunakan oleh kelas kontrol adalah Pembelajaran Berbasis Masalah (PBL). Hasil penelitian menunjukkan bahwa kemampuan pemecahan masalah siswa dengan menggunakan model pembelajaran CBR sebesar 44% dalam interpretasi tinggi dan sebesar 56% dalam interpretasi sedang. Sedangkan pembelajaran menggunakan model pembelajaran PBL sebesar 28% dalam interpretasi tinggi, sebesar 56% dalam interpretasi sedang dan 16% dalam interpretasi rendah. Sementara berdasarkan hasil uji hipotesis diperoleh nilai zhitung = -3.089 lebih kecil dari ztabel = -1.64. Hasil pengujian ini menunjukan bahwa Ho ditolak atau Ha diterima, artinya ada perbedaan secara signifikan antara kemampuan pemecahan masalah siswa yang menggunakan model pembelajaran CBR dan siswa yang menggunakan model pembelajaran PBL. Simpulan penelitian ini menunjukkan bahwa penggunaan CBR yang dirancang selama penelitian ternyata terbukti memberikan pengaruh terhadap kemampuan pemecahan masalah oleh sisw

Accordingly, based on the conclusion it was recommended that the implementation of folklore assisted values clarification technique could be sustainably socialized in order to improve the development of the students' Indonesian character since they were in the Elementary School. Key-words: Values Clarification Technique, folklore, Indonesian character

Student Perceptions on Service Quality of Higher Education: an Empirical Study

Educational literatures suggest that there is mounting pressure from customers of higher education to close the gap between their expectation of institutional performance and the actual performance (Widrick et al., 2002; Pariseau and Mc Daniel, 1997; Shank et al., 1995). Therefore, it is imperative that higher educations actively monitor the quality of their service. This study deals with measuring the service quality in higher education. The service quality of higher education in this research is defined as the difference between perception of performance and expectation of higher education. The instrument from Shank et al. (1995) was used in this study. The questionnaires were sent to students from some big universities in Jakarta. The t test was used to analysis the dat

Analisis Pengaruh Penerapan Akuntansi Manajemen Lingkungan dan Strategi terhadap Inovasi Produk dan Inovasi Proses (Studi Empiris pada Perusahaan Manufaktur yang Terdapat di Provinsi Riau)

Increased awareness regarding environmental issues has encouraged organizations to use environmental management accounting, which has been said to deliver many benefits to users, including an increase in innovation. This study aims to examine the effect of the implementation of environmental management accounting and strategy of the company's innovation. That innovation is product innovation and process innovation. Using survey data from management accountans manufacturing company located in Province Riau. The sample used is manufacturing company's located in Province Riau. The sample used some 30 large-scale manufacturing firms in Province Riau. The analytical method used is with the help of sofware Smart PLS. Parameter Significant tested by comparing the value tstatistic with ttable, where the value tstatistik>ttabel at 0,05 confidence level, its meaning there significant influence between independent variabel with dependent variabel. The result indicate that there is a positive effect between prospector strategy with environmental management accounting at tstatistic value 6,409. Environmental management accounting use has a positive effect with process innovation at tstatistic value 3,249, but not with product innovation at tstatistic value 1,113.

Korelasi Antara Konsentrasi Oksigen Terlarut Pada Kepadatan Yang Berbeda Dengan Skoring Warna Daphnia Spp. [Correlation Between Dissolved Oxygen Concentration in Different Densities with Color Scoring of Daphnia Spp.]

Dissolved oxygen is the parameters key of water quality. Low level of dissolved oxygen can affect the function and slow growth, can even cause death to fish in hypoxia condition. The aims of this experiment were to determine the effect of population density of Daphnia spp. of dissolved oxygen concentration and the correlation between dissolved oxygen concentration with color scoring of Daphnia spp. This method was experimental with Completely Randomized Design as experiment design with 6 treatments and 4 replications. The treatment that was given were the differences of Daphnia spp. density that consisted of treatment A (50 individu/200 ml), treatment B (250 individu/200 ml), treatment C (450 individu/200 ml), treatment D (650 individu/200 ml), treatment E (850 individu/200 ml), and treatment F (1050 individu/200 ml). The results showed that the difference of Daphnia spp. density showed highly significant effect of dissolved oxygen concentration of treatment medium (p<0,01). In addition, this experiment also showed that the dissolved oxygen concentration in treatment medium showed negative correlation with color score of Daphnia spp

Pengaruh Alga Merah (Kappaphycus Alvarezii) Terhadap Mutu Ikan Kembung (Rastrelliger SP.) [ Effect of Red Algae (Kappaphycus Alvarezii) on the Quality of Mackerel (Rastrelliger SP.)]

Kembung fish (Rastrelliger sp.) is a pelagic fish with high catching production volumes. The high catching volume require the fishermen and traders to maintain the quality of fish because fish is highly perishable product. Formalin abbuse as a substance to inhibit deterioration of fish induce natural substances exploration as formalin substitute in the field. One of these natural substances which widely cultivated in Indonesia is Kappaphycus alvarezii. This study aim to determine the effect of red algae (K.alvarezii) on the quality of kembung fish. The research method is experimental with a Completely Randomized Design (CRD). The treatment used is different soaking solution concentration, namely A (K.alvarezii 0%), B (K.alvarezii 25%), C (K.alvarezii 50%), D (K.alvarezii 75%) and E (formalin 1%) with four repetitions in each treatment. The primary parameters measured were the total bacterial count and organoleptic of kembung fish. The secondary parameters measured were pH of kembung fish meat. The data analyzed by Analysis of Variance (ANAVA) and the differences between treatments were determined by Duncan\u27s Multiple Range Test. The results showed that the red algae (K.alvarezii) with concentrations 0%, 25%, 50% and 75% significantly (p<0,05) on the quality of kembung fish. K.alvarezii able to inhibit the bacterial growth, but the organoleptic value (visibility, odor and texture) is lower than formalin. Based on these results, further research is needed regarding the use of appropriate concentrations so that the quality of kembung fish maintained as before the treatment (either from the total bacterial count and organoleptic value)
