Judul: The Role of Leading Sectors in Supporting the  Economic Growth of East Java Province Before and During the Covid-19  Pandemic
Abstrak: Jawa Timur merupakan salah satu penggerak perekonomian Indonesia karena merupakan penyumbang PDRB terbesar kedua setelah DKI Jakarta. Namun, pada tahun 2020 perekonomian Jawa Timur menunjukkan kontraksi pertumbuhan hingga nilainya mencapai -2,33 persen. Hal tersebut tidak lepas dari adanya pandemi Covid-19 yang menyebabkan sebagian lapangan usaha juga menunjukkan pertumbuhan negatif. Dalam rangka mencapai tujuan dan sasaran pembangunan daerah terkhusus pertumbuhan ekonomi daerah secara optimal di Provinsi Jawa Timur, maka pembangunan daerah dapat disusun menurut tujuan antar sektor. Dengan menggunakan analisis deskriptif, pendekatan Location Quotient (LQ), pendekatan Shift Share, dan overlay melalui nilai PDRB Rill menurut lapangan usaha berdasarkan harga konstan 2010 didapatkan empat sektor unggulan diantaranya sektor industri pengolahan; perdagangan besar dan eceran, reparasi mobil dan sepeda motor; penyediaan akomodasi dan makan minum; informasi dan komunikasi. Keempat sektor unggulan tersebut memiliki peran penting dalam mendukung pertumbuhan ekonomi di Jawa Timur karena memiliki laju pertumbuhan yang cepat, kontribusi yang tinggi, dan pangsa pasar yang luas baik sebelum adanya pandemic maupun saat pandemi covid-19. Sehingga pemerintah perlu memprioritaskan sektor-sektor unggulan tersebut dalam mendukung pertumbuhan ekonomi di Provinsi Jawa Timur., East Java is one of the driving forces of Indonesia's economy as it is the second-largest contributor to the Gross Regional Domestic Product (PDRB) after DKI Jakarta. However, in 2020, the economy of East Java experienced a contraction with a growth rate reaching -2.33 percent. This was primarily due to the impact of the Covid-19 pandemic, which led to negative growth in several sectors. In order to achieve the objectives and targets of regional development, especially in terms of economic growth in East Java Province, regional development can be structured according to inter-sectoral goals. Through descriptive analysis, the Location Quotient (LQ) approach, the Shift Share approach, and overlay using the Real Gross Domestic Product (PDRB Rill) based on constant prices in 2010, four leading sectors were identified. These sectors are the manufacturing industry, wholesale and retail trade, motor vehicle and motorcycle repair, accommodation, and food services, as well as information and communication. These four leading sectors play a crucial role in supporting economic growth in East Java due to their rapid growth rate, high contribution, and broad market share, both before and during the Covid-19 pandemic.Hence, the government needs to prioritize these leading sectors to support economic growth in East Java Province.

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
