Judul: Karakteristik Wisudawan Berdasarkan Indikator Kesuksesan Mahasiswa (Studi Kasus: Program Sarjana IPB)
Abstrak: Karakteristik dari mahasiswa yang sukses dapat dijadikan sebagai indikator untuk mengevaluasi program pendidikan. Indikator yang digunakan pada penelitian ini adalah indeks prestasi kumulatif (IPK) akhir, lama studi, dan predikat kelulusan. Beberapa pendekatan diimplementasikan untuk menganalisis karakteristik, yaitu analisis gerombol, analisis korespondensi berganda, dan regresi logistik biner. Analisis gerombol memberikan informasi departemen berdasarkan karakteristiknya. Hasil dari analisis gerombol yaitu terdapat empat gerombol departemen. Analisis korespondensi berganda memberikan informasi kedekatan variabel IPK TPB dengan variabel indikator keberhasilan yang lainnya. Beberapa variabel yang berpengaruh terhadap lama studi adalah jenis kelamin, beasiswa, jalur masuk dan TPB GPA. Hasil tersebut dianalisis dengan regresi logistik biner.

Judul: Identifikasi Faktor-Faktor yang Berperan Terhadap Pencapaian Indeks Prestasi Kumulatif Mahasiswa Departemen Statistika IPB
Abstrak: Kecenderungan globalisasi dan tingginya tuntutan masyarakat menyebabkan semakin ketatnya persaingan antara para pencari kerja khususnya dengan latar belakang pendidikan Strata l. Kesadaran akan hal tersebut menyebabkan, Institut Pertanian Bogor (lPB) menetapkan standar persentase lulusan dengan IPK minimal tiga sebagai salah satu indikator keberhasilan kinerja program pendidikan untuk kategori output. Berdasarkan indikator tersebut, maka mahasiswa IPB dapat dikelompokkan menjadi dua, yaitu mahasiswa yang berhasil mencapai IPK minimal tiga dan mahasiswa yang gagal mencapai IPK minimal tiga. Penelitian ini dilakukan untuk mengidentifIkasi faktor-faktor yang berperan terhadap keberhasilan mahasiswa Departemen Statitika IPB dalam mencapai IPK minimal tiga pada semester lima. Untuk keperluan itu, maka digunakan analisis regresi logistik biner dengan 17 peubah bebas, yang akan dilihat pengarubnya terhadap IPK semester 5. Bahan pada penelitian ini diperoleh dari survei terhadap mahasiswa Departemen Statistika angkatan 40,41,42 dan 43 dengan menggunakan kuesioner. Peubah jenis kelamin, IPK TPB, waktu pemilihan jurusan, dan pekerjaan paruh waktu pada semester 3 merupakan faktor-faktor yang berperan terhadap pencapaian Indeks Prestasi Kumulatif.

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
