Penyerapan Pakan Berbahan Dasar Kacang Hijau (Vigna radiata) pada Mencit Betina (Mus musculus)
Get PDFMencit (Mus musculus) adalah hewan model utama dalam penelitian biomedis. Kebutuhan akan pakan untuk pertumbuhan mencit mendorong pengembangan pakan alternatif dengan formulasi sesuai kebutuhan nutrisi. Salah satu bahan yang dapat digunakan adalah kacang hijau (Vigna radiata). Penelitian ini menerapkan pakan alternatif dari kacang hijau (Vigna radiata) untuk menunjang pertumbuhan mencit sebagai hewan model laboratorium dan mengamati penyerapan pakan yang diberikan. Penelitian ini bertujuan untuk membandingkan penyerapan pakan berbahan dasar kacang hijau pada berbagai variasi konsentrasi terhadap dengan pakan komersial. Perlakuan pada penelitian ini adalah kelompok kontrol (100% pakan komersial), KH85 (85% kacang hijau), KH75 (75% kacang hijau), KH65 (65% kacang hijau), dan KH55 (55% kacang hijau). Perlakuan dan pengambilan data dilakukan setiap hari selama dua bulan. Setiap mencit ditimbang sebelum dan sesudah makan untuk menentukan berapa banyak pakan yang mereka konsumsi. Mencit juga ditimbang setelah defekasi untuk menentukan berapa banyak pakan yang diserap pencernaan mencit. Berdasarkan hasil penelitian, perlakuan KH65 memiliki nilai penyerapan pakan yang tertinggi dibandingkan perlakuan lain, meskipun tidak terdapat perbedaan nyata dari pakan yang dimakan dan diserap dari seluruh perlakuan. Mencit dapat menyerap formulasi pakan berbahan dasar kacang hijau sebaik pakan komersial. Efisiensi pakan dapat dipengaruhi oleh digestibilitas bahan pakan, kebutuhan energi untuk menjaga berat badan, juga efisiensi pertumbuhan jaringan tubuh. Pada mencit betina, penyerapan pakan berbahan dasar kacang hijau setara dengan pakan komersial BR II sehingga pakan alternatif kacang hijau berpotensi menjadi pakan alternatif
Pengaruh Invigorasi Benih dengan Berbagai Zat Pengatur Tumbuh Alami terhadap Pertumbuhan Sawi Hijau
Get PDFSawi hijau (Brassica juncea) menjadi salah satu sayuran yang banyak diminati masyarakat karena manfaat dan kandungan gizinya, sehingga ketersediaan sawi hijau di pasar harus ditingkatkan agar dapat memenuhi permintaan masyarakat. Untuk meningkatkan ketersediaan sawi hijau dapat dilakukan dengan memastikan benih yang digunakan memiliki kualitas baik yaitu dengan memberikan perlakuan pada benih (invigorasi) sebelum ditanam. Penelitian ini dilakukan untuk mengetahui pengaruh berbagai ZPT alami beserta konsentrasi dan lamanya waktu perendaman yang efektif bagi perkecambahan dan pertumbuhan sawi hijau. Perlakuan invigorasi dilakukan dengan merendam benih sawi hijau dengan berbagai ZPT alami selama 1 jam dan 2 jam setelah itu benih disemai menggunakan rockwool. Parameter yang diamati adalah daya viabilitas dan daya vigor benih. Daya viabilitas benih, yang mencakup daya berkecambah (%), laju perkecambahan (hari), dan indeks kecepatan perkecambahan (IKP) serta indeks vigor benih yang mencakup kecepatan tumbuh benih (%), dan keserempakan tumbuh benih (%) dari semua perlakuan tidak menunjukkan perbedaan yang signifikan. Hal ini dapat disebabkan oleh kualitas benih yang masih baik dan perendaman yang dapat membantu mengaktifkan hormon giberelin. Hal ini menyebabkan baik benih yang diberi perlakuan invigorasi dengan ekstrak zat pengatur tumbuh dan direndam air tidak terdapat perbedaan yang signifikan

Pola Morfologi dan Perkembangan Kecamatan Natar
Get PDFThe development of a city takes place rapidly due to its attractiveness from both economic and non-economic sides. Rural conditions that are inversely proportional to urban areas drive urbanization. Natar District, part of the Bandar Lampung Metropolitan Area and adjacent to Bandar Lampung City, has undergone changes in morphological patterns. Identifying the morphology of a city area is critical for its development to avoid morphological defects or urban sprawl. This research used a deductive approach, referring to Smailes’ theory, identifying morphology using 3 components: road network patterns, land use and building patterns and densities. In 2012, the morphological pattern in Natar District was linear beaded with the Lintas Sumatra Road as a linear line and Radin Inten II Airport Area, Rejosari Station, Natar Traditional Market, and Hajimena Village as beads (morphological core). In 2022, the morphological pattern in Natar District has developed, still having beaded linear pattern, but there are an additional 2 beads as the core morphology, namely the office, trade and services areas Merak Batin and Natar Toll Exit Area. The development of Natar District is influenced by external factors such as its position adjacent to Bandar Lampung City and internal factors such as facilities and infrastructure
