Judul: Hubungan kausalitas inflasi IHK (Indeks Harga Konsumen) dan inflasi inti dengan analisis VAR
Abstrak: Inflasi inti, yang dihitung setiap bulan, dapat berperan dalam perumusan kebijakan moneter karena mampu menjadi indikator inflasi yang lebih tegar dalam mengantisipasi kejutan-kejutan temporer. Analisis VAR digunakan dalam pengujian kausalitas peubab inflasi IHK dan inflasi inti untuk mengetahui adanya pengaruh dari kejutan-kejutan temporer yang terdapat pada peubah inflasi IHK terhadap inflasi inti dan sebaliknya. Hasil uji kausalitas memperlihatkan kedua peubah tidak memiliki hubungan sebab-akibat atau dapat dikatakan bahwa kedua peubah bergerak secara bersamaan. Hal tersebut mengindikasikan tidak adanya pengaruh lag pada kedua peubah tersebut. Dengan demikian analisis regresi biasa dapat digunakan untuk mengetahui hubungan antar dua peubah. Hasil analisis dekomposisi keragaman menunjukkan peubah inflasi IHK merupakan peubah bebas dan inflasi inti sebagai penbah tak bebasnya. Persamaan regresi yang dihasilkan adalah inflasi inti= 0.3578+0.2889 inflasi IHK Berdasarkan analisis respon impuls baik peubah inflasi IHK maupun inflasi inti merespon kejutan yang terdapat pada dirinya atau pada peubah lainnya dengan cepat. Pada periode kurang dari setahun kejutan tersebut sudah hilang pengaruhnya.

Judul: Perhitungan Inflasi Inti (Core Inflation) di Indonesia Melalui Pendekatan Metode VAR serta Pengaruhnya
Abstrak: Masalah inflasi selalu menjadi topik yang menarik untuk dibahas dalam perekonomian, terutama karena masalah inflasi tidak pernah lepas dari negara mana pun di dunia dari waktu ke waktu. Stabilitas harga adalah salah satu dari tujuan lain kebijakan ekonomi makro selain full employment dan pertumbuhan sehingga melihat faktor-faktor penyebab dan yang berkaitan dengan inflasi menjadi sangat penting.

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
