Judul: Pengaruh Efek Tempo dan Efek Kuantum pada Angka Kelahiran Total
Abstrak: Pada karya ilmiah ini dibahas pengaruh efek tempo dan efek kuantum pada Total Fertility Rate (TFR) untuk ukuran periode maupun kohort. Efek tempo ditandai dengan perubahan rata-rata umur melahirkan wanita, sedangkan efek kuantum ditandai dengan perubahan intensitas kelahiran. Metode yang dilakukan dalam mempelajari efek tempo dan efek kuantum pada TFR terdiri dari beberapa tahap. Langkah pertama adalah membangkitkan data hipotetik dari angka kelahiran wanita menggunakan fungsi gamma. Kemudian akan diformulasikan TFR yang telah disesuaikan efek tempo dan efek kuantum (TFRA). Dari hasil simulasi yang dilakukan menunjukkan bahwa efek tempo yang ditandai dengan adanya peningkatan rata-rata umur melahirkan dan efek kuantum yang ditunjukkan dengan adanya penurunan rata-rata jumlah anak yang dilahirkan akan membuat nilai TFRA lebih realistis dibanding TFR yang tidak disesuaikan efek tempo dan efek kuantum.

Judul: Pendugaan Taklangsung Angka Fertilitas Total Menggunakan Rasio Anak-Wanita
Abstrak: Fertility is an important factor in population projection. Measurement of fertility can be used as a consideration in the decision making of regional planning and economic development. As a developing country, Indonesia has difficulties in birth data collecting such that Indonesia has not any vital statistics that can be used as a reference. For these conditions, fertility measurements are then performed by indirect methods such as Rele, Palmore, Gunasekaran-Palmore, last live birth and own children methods. TFR (Total Fertility Rate) is the average number of children that would be born to a woman over her life time. CWR (Child-Woman Ratio) is the number of children born to women of childbearing age. In this paper, the Palmore method will be modified by including implied Total Fertility Rate (iTFR) and modified Total Fertility Rate (iTFR*) variables. Referring to the Palmore method, regression equations were made to estimate the TFR by using either iTFR or iTFR* as one of the independent variable candidates. Based on census data of the population of Indonesia in 2010, TFR estimation using iTFR produces better estimate than iTFR*. It is confirmed by the fact that MAPE values for both estimation are 6.95% and 4.06%, respectively.

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
