Judul: Faktor sosial ekonomi khalayak yang mempengaruhi persepsi terhadap acara siaran radio : Kasus di kelurahan Tegallega Kotamadya Bogor Propinsi Jawa Barat
Abstrak: Teknologi komunikasi massa pada masa sekarang ini sudah sangat maju berkembang, baik secara program maupun peralatan tekniknya. Informasi merupakan suatu kebutuhan yang perlu diterima oleh khalayak dalam rangka mengikuti perkembangan informasi yang semakin maju dan bervariasi. Semakin banyaknya informasi maka dituntut adanya persamaan persepsi antara pembuat program dengan penerima pesan. Berbagai media massa terlibat dalam menyebarkan beragam informasi, termasuk radio sebagai media informasi yang dimiliki oleh khalayak. Persepsi terhadap acara siaran radio yang berbeda antara individu yang satu dengan individu lainnya sesuai dengan selera yang dimilikinya. Tujuan penelitian ini adalah mengetahui persepsi masyarakat tentang acara siaran radio. Penelitian ini kasus di Kelurahan Tegallega Kotamadia Bogor Propinsi Jawa Barat pada tanggal 15 Desember 1993 sampai 12 Pebruari 1994. Penelitian ini juga ingin mengetahui faktor sosial ekonomi khalayak yang mempengaruhi bentuk persepsi khalay- ak dilihat dari keadaan sosial ekonominya. ...

Judul: Pengaruh Program Siaran Radio Pertanian Ciawi Bagi Pendengarnya (Kasus Pendengar di Desa Cileungsi, Kecamatan Ciawi, Kabupaten Bogor)
Abstrak: This research aimed to analize the influence of radio programs towards listeners. These research goals are: (1) to analyze listeners exposure towards radio programs and it’s assessment towards radio programs (2) to analyze factors that effect radio programs exposures towards listeners and the assessment of radio programs by listeners (3) to analyze the influence of radio programs towards listeners and factors that influencing it. The result show that listeners exposure towards radio programs and it’s assessment towards radio programs were influenced by listeners characteristic. Among several variables of listeners characteristic that have significant relation towards radio programs exposure is mass media ownership with listening duration. Meanwhile, listeners characteristics which have a relation with listeners assessment towards radio programs are mass media ownership with the assessment of radio broadcasting material, the announcer, and the duration of the programs, the age of listeners and it’s assessment towards the radio programs are broadcasted, listeners occupation and it’s assessment towards radio broadcasting material and how its been presented. The results also shows that the radio programs that have been broadcasted gave several effects. The Effect of radio programs towards listeners are the increasing of cognitive and affective aspects.

Judul: Systematics of Desmos (Annonaceae) in Malesia
Abstrak: Desmos is a woody climbing genus of Annonaceae which has been widely used as traditional medicine in several countries such as China, Indo-China, Thailand, and Peninsular Malaysia to treat dysentery, vertigo, fever, and postpartum. Phylogenetic studies on Desmos showed a close relationship between Desmos and Dasymaschalon. They share similar moniliform monocarpic fruits, but their flowers are different. It has been debated among Annonaceae researchers whether both genera should be treated as the same or distinct genus. Therefore, investigation on the taxonomic delimitation of Desmos species and Dasymaschalon will be necessary. Plastid genome (plastome) identification, leaf epidermal section of Desmos species and Dasymaschalon species, a taxonomic revision of Desmos in Malesia using morphological data, the spatial distribution of Desmos species in Malesia, and morphological and genetic variation in Desmos chinensis population using ISSR marker were used to investigate taxonomic delimitation of Desmos. Plastome study of Desmos chinensis and Dasymaschalon dasymaschalum was carried out to determine the origin, evolution, phylogenomics, and identify marker candidates for Desmos and Dasymaschalon or with other genera in Annonaceae. We discovered that the plastome of Desmos chinensis was circular with the size of 167,677 bp (smaller than Dasymaschalon dasymaschalum), consist of 111 genes, including 78 protein-coding genes, 29 transfer RNAs, and 4 ribosomal RNAs. The plastome showed a typical quadripartite structure, i.e., large single copy (LSC), small single copy (SSC), and two inverted repeats (IRs). The plastome of Dasymaschalon dasymaschalum was 191,488 bp in length, which also exhibited a typical quadripartite structure (LSC, SSC, and two IRs). Desmos chinensis and Dasymaschalon dasymaschalum showed different copies of accD, ndhD, ndhF, rps18, and ycf2. Protein coding genes of rpoB, rpoC1, rbcL, matK, rpl32, infA, and rpl36 were identified based on nucleotide diversity, sequence variability, and parsimony-informative sites. The genes are defined as molecular marker candidates of plastome for phylogenetic, barcoding, and population genetic research. We predicted that Desmos chinensis and Dasymaschalon dasymaschalum separated at ca. 64 million years ago during the Paleocene. Leaf anatomical feature study was carried to support the taxonomic delimitation of interspecific Desmos and intergeneric of Desmos and Dasymaschalon. Leaf anatomy in the paradermal section of 20 taxa (12 species of Desmos, eight species of Dasymaschalon) have been carried out. According to the leaf epidermal section, Desmos and Dasymaschalon are two distinct genera mainly distinguished based on the anticlinal wall undulation of epidermal cells and supported by variation of the crystal type and size. The anticlinal wall undulation of Desmos was almost straight to slightly wavy and never sinuous; meanwhile, Dasymaschalon varies from almost straight to deeply sinusoid. The crystals of Desmos consist of rhombohedral, druse type A, and druse type B crystals, whereas Dasymaschalon has prism, druse type A, druse type B, and druse type C crystals. The recent taxonomic revision using the morphological data was mainly based on the examination of about 1374 specimens from BO, L, WAN, ANDA, SING, SAN, K, P, HUH herbaria. The Desmos species in Malesia consists of eight species: D. acutus, D. chinensis, D. chryseus, D. dunalii, D. pedunculosus, D. subbiglandulosus, two new records: D. lawii and D. macrocarpus, and one
