Rattan Species at Three Mounts in Gunung Halimun National Park, West Java

Management of forest is believed that many basic knowledges about the nature of the forest is needed. One of them is to develop the forest as a resource of cane industry in a sustainable way. For this purpose, the composition, distribution and density of rattan species in Gunung Halimun National Park (INGH) were studied as a model. Data were collected from December 1994 until May 1995. For species composition on rattan in TNGH, three areas were observed namely in Mt. Kancana, Mt. Pameungpeuk and Mt. Pangkulahan using a continues belt transect method, from the elevation of 800-1,400 m above sea level. It was found that there were 13 species of rattans in the region. In terms of species richness and densities, Mt. Pameungpeuk comes first, followed by Mt. Pangku1ahan and Mt. Kancana. Calamus beteroides, C.javensis, Daemonorops melanocbaetes, and Plectocomia elongata are dominant both in seedling and nature forms. The nature rattans are relatively abundant in areas less than 1,000 meter above sea level and decrease in number of species as well as the minimal population in the higher altitude. Calamus ornatus grows well at 800-1,400 m asl, while Daemonorops ruber at 800-1,500 m asl, D.oblonga at 800-1,400 m asl

An Overview on the Conservation Status of Mersawa (Anisoptera Costata Korth.) in Java

Anisoptera costata Korth., which has a commercial name of mersawa grows and proliferates naturally, often gregarious, in semi-evergreen dipterocarp forest and evergreen forest in areas with seasonal climate and rare but widespread in lowland everwet forest from sea level up to 700 m in continental S.E. Asia, Malay Peninsula, Borneo, Sumatra, and Java (Ashton, 1982). In Java, it has been recorded to occur only in Banten (Backer & Bakhuizen van den Brink,1963) and in Leuweung Sancang Nature Reserve (LSNR) (Kalima, 2006

Asian American and Pacific Islander Presidential Fellows Report

Since the 2010 Census, Oregon’s Asian American population has grown by 42.3% and its Pacific Islander population has grown by 57.3%, making these groups the fastest growing in the state (US Census Bureau, 2019; US Census Bureau, 2020a). In the Portland metropolitan area, these populations experienced a growth of 42.1% and 64.7%, respectively (US Census Bureau, 2019; US Census Bureau, 2020a). Although Asian Americans and Pacific Islanders (AAPIs) are often lumped together as a monolith, they differ from each other in ethnicity and also culture, politics, socioeconomic status, language, religion, immigration status, and migration and colonization histories. Given the history of anti-Asian exclusion laws in the US and the colonization of the Pacific Islands, AAPIs are often invisible in the US cultural, social, and political landscapes. Furthermore, the racist stereotype of the model minority — successfully assimilated, high-achieving, and upwardly mobile — erases the heterogeneity of AAPIs and their long history of racism. More recently, racist phrases associated with the COVID-19 pandemic have fueled anti-AAPI racism and xenophobia. As an anchor institution, Portland State University aims to provide all Oregonians with an opportunity to pursue a college education in an environment that promotes access, inclusion, and equity as its pillars of excellence. With its proximity to organizations that serve AAPIs, such as APANO (Asian Pacific American Network of Oregon), Asian Health & Services Center, and Asian Family Center, Portland State has an enormous opportunity to meet the higher education needs and aspirations of AAPIs, especially among those who live in the Portland metropolitan area where much of their population growth has been concentrated. In order to attract, retain, and graduate AAPI students, Portland State must distinguish itself as an institution that values equity in higher education and is inclusive of all students, including those who identify as AAPI. The needs of AAPI students at PSU, however, have long been overlooked and misunderstood. Although more than 13% of undergraduate and about 8% of graduate students identify as AAPI, Portland State still does not have an AAPI Studies Program despite almost a decade of activism led by students with support from faculty and staff. Recently reported findings from Students First, a campus-wide initiative focused on student success, are also troubling. Compared with other racial groups, Pacific Islander students have among the lowest retention and graduation rates. And the 2020 Student Experience Survey (Loper & Garrity, 2020) shows that, compared to their peers, Asian American students experience greater challenges related to academic support, commuting to campus, and emotional or mental health. Cultural representation among faculty and staff on college campuses is critical for reducing the negative effects caused by racist stereotypes such as the “model minority” and “forever foreigner” and to 3 increase a sense of belonging (Yeh, 2004; Poon et al., 2016). Yet the number of AAPI faculty and staff at PSU has not kept pace with the increasing numbers of AAPI students. This report presents three priority actions that Portland State can take towards fulfilling its commitment to ensuring that all of their students, including those who identify as AAPI, have the opportunity and support they need to experience the transformative power of a college education. ACTION 1: Establish an Asian American and Pacific Islander Studies Program in the School of Gender, Race and Nations by the 2022 Fall term. ACTION 2: Collect disaggregated and nuanced data to better understand the experiences and challenges faced by Asian American and Pacific Islander students at Portland State. ACTION 3: Establish policies and practices to retain, recognize, and reward Asian American and Pacific Islander faculty and staff whose efforts help to enable the University to deliver on its access mission

Potensi Akar Kuning (Fibraurea Tinctoria Lour.) Di Hutan Rawa Gambut, Kabupaten Kapuas, Provinsi Kalimantan Tengah (Potential of Akar Kuning (Fibraurea Tinctoria Laur.) in Peat-swamp Forests, Kapuas District, Central Kalimantan Province)

Hutan rawa gambut Kalimantan umumnya telah mengalami kerusakan karena adanya eksploitasi dan aktivitas manusia yang berlebihan. Tumbuhan akar kuning (Fibraurea tinctoria Laur.) dikenal sebagai obat herbal yang digunakan secara tradisional oleh masyarakat Kalimantan Tengah. Penelitian ini bertujuan untuk memperoleh informasi potensi, sebaran, dan asosiasi akar kuning di hutan Blok Release, Kecamatan Mantangai, Kabupaten Kapuas, Provinsi Kalimantan Tengah. Pengambilan data dilakukan dengan cara inventarisasi dengan metode pengambilan contoh secara purposif, dibuat dua jalur transek dan peletakan jalur (transek) pada lokasi ditemukan tumbuhan akar kuning. Kemudian dibuat plot berukuran 5 m x 5 m dan 2 m x 2 m secara selang seling sebanyak 80 plot dengan luasan 0,2 ha. Hasil penelitian menunjukkan bahwa potensi Fibraurea tinctoria di hutan Blok Release adalah 375 individu/ha dan 675 individu/ha, dimana tingkat semai lebih dominan daripada tingkat pancang (40 individu/ha dan 70 individu/ha). Adapun pola sebaran akar kuning menyebar secara seragam atau teratur. Tingkat asosiasi menggunakan indeks Ochiai (OI), menunjukkan nilai kekuatan asosiasi yang terbesar dimiliki oleh Shorea balangeran dan Mangifera similis (OI = 0,63), kehadiran Freycinetia angustifolia memiliki tingkat asosiasi rendah (OI = 0,48-0,23) dan tingkat asosiasi terendah (OI = < 0,22) dtemukan pada 17 jenis. Jenis tumbuhan yang berasosiasi terhadap Fibraurea tinctoria adalah tanaman yang berpotensi sebagai bahan baku obat. Informasi mengenai populasi, sebaran dan pola sebaran, serta asosiasi akar kuning, diharapkan dapat menjadi dasar dalam pengelolaan akar kuning secara lestari di alam
