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: Codiaeum Malesia
Abstrak: The Malesian genus Codiaeum has been revised based on the morphological character using available herbarium collections in Herbarium Bogor iense and loan specimens from Rijksherbarium Leiden. The study is based on the observation of 350 specimens. Eleven species have been recognized, namely Codiaeum variegatum, C. luzonicum, C. palawanense, C. trichocalyx, C. megalanthum, C. cilliatum, C. affine, C. tenerifolium dan C. hirsutum, C. macgregorii, C. ludovicianum. number of species is found in the Philippines The highest (8 species), Two species (C. tenerifolium and C. ludovicianum) endemic in Lousiade Archipelago of the New Guinea and C. affine endemic in Banguey Island. C. variegatum is widespread by nature or in cultivation almost in all of Malesian region. C. cillia tum is a species in the earliest level among the other species according to 20 selected characters.
