Judul: Minat siswa kelas 3 IPA terhadap bimbingan belajar
Abstrak: Penelitian survei yang mengambil topik minat siswa terhadap bimbingan belajar ini dilaksanakan pada bulan Maret 2003 di kota Bogor. Penelitian ini dilakukan untuk mengetahui bagaimana minat iswa terhadap bimbingan belajar, apa saja yang menjadi latar belakang dan menjadi pertimbangan sisiva dalam memilih bimbingan belajar, dan kemudian bagaimana pandangan siswa setelah mengikuti Cambingan belajar. Metode Analisis yang digunakan adalah analisis deskriptif dan regresi logistik. Regresi logistik digunakan untuk mengetahui faktor apa saja yang mempengaruhi siswa mengikuti Bimbingan belajar. Dari hasil survei diketahui minat siswa untuk mengikuti SPMB cukup besar. Siswa pun mengakui Saliwa pada umumnya mereka menghadapi kesulitan untuk mengerti pelajaran di sekolah walaupun pada dasamya permasalahan itu berasal dari cara belajar siswa itu sendiri. Untuk menghadapi SPMB, Siswa merasa persiapan yang diberikan di sekolah terasa belum cukup, dan mereka memilih untuk mengikuti bimbingan belajar. Bimbingan belajar yang mereka pilih adalah bimbingan belajar yang berkualitas baik yang telah banyak meluluskan siswanya di SPMB. Dengan menggunakan regresi logistik, dapat diketahui bahwa ada tiga buah peubah yang berpengaruh terhadap keikutsertaan siswa di bimbingan belajar yaitu: jenis kelamin, pendapatan orang tua dan dorongan dari orang tua kepada siswa untuk mengikuti bimbingan belajar. Untuk program intensif, siswa sangat berminat untuk mengikutinya sebagai tahap terakhir dalam persiapan mereka menghadapi SPMB.

Judul: Faktor-faktor yang mempengaruhi minat siswa melanjutkan pendidikan ke perguruan tinggi dengan menggunakan Regresi Logistik (Studi Kasus: minat siswa SMU/sederajat di Kab.Garut terhadap STAI Al- Musaddadiyah)
Abstrak: Interest is a desire that tends to settle in a person to drive on a particular option as a necessity, then continue to be realized in real action with the attention on an object that wants to seek information as knowledge for themselves. Logistic regression is used for describing between dependent variable and independent variable to categorical data. In logistics regression analysis, y=0 showed that students are not interested in continuing their study while y=1 showed that students are interested in continuing their study to the university. STAI characteristics of the students who most of the madrasah aliyah. look at the existing market potential, it is necessary to investigate any factors that influence students' interest to continue their education into college. one analysis can be used to model the relationship is logistic regression. from the regression results indicate that factors that affect, among others, the job of parents, parents' education, average income of parents, the students achievement and there were some brothers or sister who continue study to college. The result of logistic regression method shows that interest that the parents education, average income of parents, motivating factor.

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
