Judul: Dampak Guncangan Sasaran Operasional dalam Mekanisme Transmisi Kebijakan Moneter: Perbandingan Inflation Targeting dan Multiple Objectives di Indonesia
Abstrak: Sejak ditetapkannya UU No. 3 Tahun 2004 tentang Bank Indonesia, tujuan Bank Indonesia yang sebelumnya memiliki tujuan ganda (multiple target) dirubah menjadi lebih fokus dalam pencapaian sasaran tunggal (single target) yaitu mencapai dan memelihara kestabilan rupiah. Dengan menggunakan metode Structural VAR, penelitian ini menganalisis perbandingan efektivitas penerapan inflation targeting dan multiple objectives di Indonesia dengan melihat pengaruh guncangan sasaran operasional dalam mekanisme transmisi kebijakan moneter di Indonesia. Penelitian ini memodelkan masing-masing kebijakan dengan menggunakan sasaran operasional yang berbeda yaitu dengan menggunakan base money (M0) dan suku bunga PUAB (Pasar Uang Antar Bank). Hasil penelitian menunjukkan bahwa kebijakan inflation targeting lebih cocok diimplementasikan di Indonesia dibandingkan dengan multiple objectives. Selanjutnya ditemukan bahwa kebijakan inflation targeting dengan sasaran operasional base money (M0) dianggap paling relevan dalam mencapai sasaran akhir target inflasi.

Judul: Monetary Policy Transmission Analysis: Comparison of Inflation Ttargeting and Flexible Inflation Targeting in Indonesia
Abstrak: Krisis keuangan global 2008, mengubah kerangka kebijakan moneter di Indonesia dari inflation targeting menjadi flexible inflation targeting serta menambahkan fokusnya tidak hanya kepada stabilitas harga namun juga stabilitas keuangan sejak tahun 2009. Kebijakan moneter suatu negara dikatakan berhasil jika tingkat inflasi mencapai target inflasi, namun yang terjadi tingkat inflasi masih jauh dari target inflasi. Oleh karena itu, tujuan penelitian ini untuk mencari kerangka kebijakan terbaik dengan membandingkan antara inflation targeting dan flexible inflation targeting di Indonesia melalui transmisi kebijakan moneter jalur suku bunga pada Bulan Juli 2005 hingga Bulan Desember 2022. Hasil penelitian ini membuktikan bahwa dengan metode Structural VAR yang dikombinasikan dengan metode Structural VECM, kebijakan flexible inflation targeting terbukti lebih baik diimplementasikan di Indonesia di bandingkan dengan kebijakan inflation targeting. Hal ini didasarkan oleh hasil estimasi yang menunjukkan bahwa responsibilitas suku bunga BI rate bekerja lebih baik saat implementasi kebijakan flexible inflation targeting. Kontribusi kebijakan moneter pada variabilitas inflasi di flexible inflation targeting memang lebih sedikit jika dibandingkan dengan inflation targeting, namun kebijakan tersebut tetap lebih baik dalam menjelaskan variabilitas inflasi. Untuk mengoptimalkan kinerja flexible inflation targeting, Bank Indonesia perlu memperkuat kebijakan suku bunga untuk mengelola inflasi.

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
