Abstract

In this paper, we study irreducible unitary representations of a real standard filiform Lie group with dimension equals 4 with respect to its basis. To find this representations we apply the orbit method introduced by Kirillov. The corresponding orbit of this representation is genereric orbits of dimension 2. Furthermore, we show that obtained representation of this group is square-integrable. Moreover, in such case , we shall consider its Duflo-Moore operator as multiple of scalar  identity operator. In our case  that scalar is equal to one.

Abstract

Kode genetik standar merupakan hasil pemikiran para ilmuwan biologi pada masanya sebagai suatu representasi gen yang disesuaikan dengan kebutuhan tubuh manusia akan protein. Gen pada kode genetik standar disajikan dalam bentuk kode triplet basa-basa nitrogen dan menjadi bahasa pengkodean gen dalam tubuh makhluk hidup yang menghasilkan  kode triplet yang berbeda. Semua kode triplet dari rantai nukleotida RNA tersebut diterjemahkan dan menghasilkan 20 macam asam amino yang akan dilepas sebagai protein dalam sel. Kumpulan basa nitrogen dalam rantai RNA dihimpun dan disajikan dalam suatu himpunan yang kemudian dicocokkan dengan   dengan dua himpunan yang memuat partisi basa-basa nitrogen berdasarkan jenis basa dan ikatan hidrogennya. Pada paper ini himpunan dicocokkan . Dengan pencocokan tersebut, maka N memiliki struktur Aljabar sebagai Grup Komutatif terhadap penjumlahan, juga membentuk Grup Faktor yang dibentuk dari subgroup Normal yaitu , dan Lapangan Galois atau GF(4). Selain dari itu,  juga membentuk struktur ruang vektor atas GF(4) sehingga . Dengan demikian terbentuklah representasi  berupa suatu multicube  berdimensi tiga yang merupakan gabungan dari 27 kubus unitary, dengan menggunakan  transformasi geometri, maka akan dilihat representasi  dari kode genetik Standar berdasarkan subgrup normal yang membentuk grup faktornya, yaitu didasarkan pada basa kuat atau basa lemah dari Nukleotida. Representasi dilakukan dengan menggunakan bantuan software Geogebra. Dari hasil representasi tersebut dapat dilihat perubahan-perubahan yang terjadi pada kode genetik standar, yang pada akhirnya dapat dipandang sebagai mutasi pada kajian ilmu Biologi Sel.

Abstract

Kemitraaan pengelolaan hutan rakyat merupakan salah satu upaya untuk meningkatkan kesejahteraan petani hutan rakyat. Pertanyaan yang ingin dijawab dalam penelitian ini adalah bagaimana kinerja kelembagaan kemitraan antara petani dengan mitra. Penelitian ini bertujuan untuk menganalisis kinerja kelembagaan kemitraan antara petani dengan tiga mitra yang berbeda yaitu industri kecil, industri besar, serta non industri. Penelitian dilaksanakan pada bulan Juli - Oktober 2012 di Kabupaten Garut, Tasikmalaya, dan Ciamis. Penelitian ini menemukan bahwa kinerja kemitraan pengelolaan hutan rakyat di lokasi studi cukup beragam yang dipengaruhi oleh hubungan sosial para pihak, kepatuhan terhadap kesepakatan perjanjian, pengawasan dan sanksi pelanggaran kesepakatan serta proporsi. Proporsi berpengaruh terhadap kelayakan finansial kemitraan. Biaya sharing input output ke agenan dapat mempengaruhi hubungan principal agent. Terdapat beberapa temuan yang perlu dipertimbangkan dalam melakukan program kemitraan, yaitu: penyiapan petani calon peserta kemitraan, dan pendekatan kepada pengusaha sebagai calon mitra.

Abstract

Parasetamol merupakan obat yang umum digunakan sebagai antipiretik dan analgesik tetapi dapat bersifat nefrotoksik apabila digunakan secara berlebih (overdosis). Buah lakum (Cayratia trifolia [L.] Domin) diketahui dapat digunakan sebagai nefroprotektif akibat parasetamol karena mengandung senyawa metabolit sekunder yang bersifat antioksidan. Tujuan dari penelitian ini adalah untuk mengetahui dosis optimal ekstrak metanol buah lakum (C. trifolia [L.] Domin) yang mampu meregenerasi nefron pada mikroanatomi ginjal tikus putih (Rattus norvegicus) yang diinduksi parasetamol. Rancangan penelitian pada penelitian ini adalah Rancangan Acak Kelompok (RAK) yang terbagi menjadi tujuh kelompok perlakuan, yaitu kontrol normal (akuabides), kontrol negatif (parasetamol), kontrol positif (obat HEPA-Q), kontrol pelarut (CMC 0,5%) dan kelompok ekstrak (115 mg/200 g BB tikus, 230 mg/200 g BB tikus dan 345 mg/200 g BB tikus). Hasil penelitian ini adalah ekstrak buah lakum dosis 230 mg/200 g BB tikus memiliki kemampuan regenerasi nefron yang optimal dengan rerata kerusakan glomerulus dan tubulus masing-masing 1,6 ± 0,54 dan 1,4 ± 0,44. Struktur mikroanatomi ginjal tikus pada kelompok ekstrak buah lakum dosis 230 mg/200 g BB tikus memiliki struktur yang tidak berbeda dengan kelompok positif.
