An analysis of the growth dynamics of a 1-ha (100 m x 100 m) permanent plot was carried out in the Danau Bangko Protected Area (DBPA) in March 2020. DBPA is part of the industrial plantation forest concession of PT Rimba Hutani Mas (PT RHM) in Jambi Province. The study aims to determine the dynamics of vegetation structure and composition between 2018 and 2020 in early regeneration forest. All trees tagged in 2018 were remeasured in 2020. Trees that had not been tagged previously but were 10 cm in diameter at breast height (DBH) were identified as a new recruit and tagged with a new number. Observations and data analysis were carried out on three stages of growth phases, namely in the tree phase ( 10 cm DBH), sapling phase (10 cm DBH), and seedling phase (height 1.5 m). The results showed that the number of species, genera, and families within the tree and sapling phases were high, but were low in the seedling phase. The dominant species in the tree phase in 2018, Alseodaphne bancana, had been replaced by Archidendron bubalinum in 2020, whereas the dominant species in the sapling phase (Rothmania sp.) and seedling phase (Aporusa microsphaera) remained the same from 2018 to 2020 . Mortality rates in all growth phases (tree, sapling and seedling) together is 4.67%. Recruitment into the tree phase from 2018 to 2020 was 2.67%, consisting of eight species, eight genera, and seven families. Within one hectare permanent plot, all members of each tree species were distributed randomly. The vertical structure of the forest area is dominated by stratum C (4-20 m height). The results of hypothesis testing for each phase (tree, sapling, seedling) were different, however overall the results showed that the plot structure and composition had changed.Studi dinamika hutan dilakukan di Kawasan Lindung Danau Bangko (KLDB) pada Maret 2020 dengan menggunakan pendekatan plot permanen seluas satu hektar (100 m x 100 m). KLDB merupakan bagian dari konsesi hutan tanaman industri PT Rimba Hutani Mas (PT RHM) di Provinsi Jambi. Penelitian ini bertujuan untuk mengetahui dinamika struktur dan komposisi vegetasi antara pengukuran tahun 2018 dan 2020, khususnya pada areal dengan tutupan Belukar Tua (BT). Diameter semua pohon yang telah diberi tanda nomor pada tahun 2018 diukur kembali. Pohon yang belum diberi tanda sebelumnya tetapi diameternya 10 cm setinggi dada (DBH) ditetapkan sebagai rekrutmen baru dan diberi tanda dengan nomor baru. Pengamatan dan analisis data dilakukan terhadap tiga tahap tahap pertumbuhan, yaitu tingkat pohon (10 cm DBH), tingkat pancang (10 cm DBH), dan tingkat semai (tinggi 1,5 m). Hasil penelitian menunjukkan bahwa jumlah spesies, jumlah marga, dan jumlah famili pada tingkat pohon dan pancang tinggi, sedangkan pada tingkat semai rendah. Jenis dominan pada tingkat pohon pada tahun 2018 adalah Alseodaphne bancana telah digantikan oleh Archidendron bubalinum pada tahun 2020, sedangkan pada tingkat pancang (Rothmania sp) dan tingkat semai (Aporusa microsphaera) merupakan jenis yang dominan baik pada tahun 2018 maupun pada tahun 2020. Angka kematian pada semua tahapan pertumbuhan bervariasi dengan rata-rata 4,67%. Rekrutmen di tingkat pohon 2,67% yang terdiri dari 8 spesies, 8 marga, dan 7 famili. Secara keseluruhan, semua spesies tersebar secara acak. Tinggi tajuk pohon didominasi oleh stratum C (tinggi 4 m - 20 m). Hasil pengujian hipotesis pada setiap tingkatan (pohon, pancang, semai) berbeda, namun hasil penggabungan semua data menunjukkan bahwa telah terjadi dinamika.

In conservation areas throughout Indonesia, there are at least 1.8 million hectares of open land in the form of damaged or degraded ecosystems following encroachment on conservation areas by local communities. Addressing this, the government of Indonesia has introduced a conservation partnership policy issued in 2018, namely the Director General of KSDAE Regulation No. P.6/KSDAE/SET/Kum.1/6/2018 concerning Technical Guidelines for Conservation Partnerships in Nature Reserves and Nature Conservation Areas. The objective of this study was to identify and analyze the impact of conservation partnerships on improving the welfare of the community in the Gunung Masigit Kareumbi Hunting Park (GMKHP). The research was conducted within the GMKHP area, with the samples taken from the community of Forest Farmer Groups (KTH) in the villages of Pelita Asih, Jaya Mekar, Sunda Mekar, Cikadu, Sukajaya, and Kaduwulung. The approach used in this study is qualitative. Data were collected by questionnaire survey, interviews, observations, and documentation in the field. Based on the results of the study, it is known that the production of pine resin tapping carried out by KTH members is as much as 29,033 kg/month or an average of 323 kg/person per month. This activity has an impact on increasing the income of KTH members by 170%, i.e. from their initial average income of Rp. 853,778 per month to become Rp. 2,307,278/month for each member. Additionally, there are also contributing funds to the neighborhood and social welfare coordinated by cooperatives, such as assistance for the poor and orphans, village treasury income, BUMDes (Village Enterprise) capital, wages for reading Qoran teachers, mosque maintenance, etc.

Producing the first issue of a new scientific journal is an exciting and stressful time for any editorial board. Producing the second issue is more quietly satisfying with different concerns. Everyone was supportive and interested in the launch, but will they now follow up with challenging papers and relevant information to share, and will colleagues use and share this journal? A significant step forwards in the production of The Indonesian Journal of Applied Environmental Studies (InJAST), is that the Online Journal System is now live. This has meant that, whereas all work for the first issue was undertaken through email communication, for this second issue, all manuscript submissions and their peer-review processes have been managed successfully online. A major and much appreciated demonstration of support for InJAST is the MoU that has now been signed between the Graduate School of Environment Management in Pakuan University and PERWAKU (Perhimpunan Cendikiawan Lingkungan Indonesia; the Indonesian Association of Environmental Scholars), one of their key collaborations being to publish collaboratively InJAST. The MoU was signed auspiciously on 5 June 2020, the 16th anniversary of PERWAKU and the 46th anniversary of World Environment Day.World Environment Day 2020 sought to engage governments, businesses, celebrities and citizens to focus their efforts on a pressing environmental issue the theme is biodiversity a concern that is both urgent and existential. Recent events, from bushfires in Brazil, the United States, and Australia to locust infestations across East Africa and now, a global disease pandemic demonstrate the interdependence of humans and the webs of life, in which they exist.â€Also to mark World Environment Day, Pakuan University and PERWAKU, together with Andalas University, held a webinar focussed on the Protection and Management of The Environment of the Covid-19 Era. This global pandemic has of course affected everyone from all walks of life, and the webinar explored the dangers of over use and destruction of the natural world, the benefits all humans derive from nature for our survival, and the demands for good focussed environmental management. Although incredibly tragic, the pandemic has perhaps focussed governments, businesses and communities alike on our relationship with nature.All such concerns lie within the globally recognised nexus of the nature crisis, the climate emergency, and unsustainable production and consumption. Environmental managers must understand and bring into account a wide array of subjects and approaches, not just science and technology but also social sciences, behavioural insights, economics, policy and regulation, and the arts and humanities, when tackling such problems. In Indonesia, and elsewhere, these challenges include deforestation, habitat loss and air pollution from forest fires, and water and air pollution from industrial and urban development. The second issue of InJAST illustrates this breadth of interest, concern, and focussed research, comprising papers on environmental policy, the UN Sustainable Development Goals, natural resources management, biodiversity of restored habitats, and progression in methodological approaches.As Editors-in-Chief, we are very pleased to see this second issue appear and encourage our colleagues from all sectors to submit their papers covering primary research, reviews, and research into policy and practice.

It is our great pleasure to announce that the very first issue of the Indonesian Journal of Applied Environmental Studies (InJAST) is now be available in both print and online. This journal has evolved from the Journal of Environmental Education which started in 2015, and was managed by the Study Programme of Population and Environmental Education, Graduate Programme of Pakuan University. Because this study programme has now become the Study Programme of Environmental Management, we have decided to establish this new journal to publish scientific articles covering broader environmental issues that are written by the Indonesian students of graduate programmes either in Pakuan and other universities or researchers. Meanwhile, the publication and management of the Journal of Environmental Education will be transferred to another relevant faculty or study programme within Pakuan University.We intend the new InJAST to be published in English (with abstracts both in English and Bahasa) so that it can reach a wider readership internationally, and we hope encourage international environmental students and scientists working in Indonesia or on topics of specific relevance to Indonesia, to disseminate their research results and findings through this journal.We are pleased to also announce that it has been agreed in principle that this new journal will be published collaboratively between the Graduate School of Pakuan University and PERWAKU (Perhimpunan Cendikiawan Pemerhati Lingkungan Indonesia, the Indonesian Association of Environmentalist Scholars). A formal Memorandum of Understanding between both parties will be signed in the near future.In this occasion, we, as the chief editors of this new journal, would like to express our gratitude to various parties and individuals who have supported this initiative, especially to Prof. Dr. H. Bibin Rubini, M.Pd. (Chancellor of Pakuan University), Prof. Dr. Ing. H. Soewarto Hardhienata (Dean of Graduate School Pakuan University), and Prof. Jatna Supriatna, Ph.D. (Chairman of PERWAKU Indonesia). We would also like to express special thanks to our national and international colleagues at Pakuan University and elsewhere, who have so generously offered their time as members of the editorial board of the journal.Last but not least, we hope that the Indonesian Journal of Applied Environmental Studies (InJAST) will provide new colour and perspectives the scientific journals published by Pakuan Univeristy, and become the vehicle of choice for environmental science students and scientists to disseminate of their work.

Regional development is a priority programme of the government of the Republic of Indonesia. The region that has received significant development is the province of Papua. The form of development in Papua Province is the division of a new autonomous region (DOB). The formation of new autonomous regions encourages development in newly created areas, especially in urban areas. Cities that are increasingly developing can trigger the flow of urbanization so that the population increases. Increasing population affects climate parameters, especially air temperature. Temperature is expected to increase as a result of an increase in the number of urban residents and the imbalance of energy in and out of the earth. This study aims to determine the effect of population on variations in temperature in Nabire and Paniai Regencies. The data used are annual average, minimum, and maximum temperature data at the Nabire and Paniai Meteorological Stations. The data is displayed in graphical form, and the correlation is calculated to be analyzed descriptively. The results of the study show that there is a strong correlation between population growth and an increase in average and minimum average temperatures. While the average maximum temperature has a weak relationship to population growth. Pembangunan daerah merupakan program prioritas pemerintah Republik Indonesia. Wilayah yang mendapat pembangunan signifikan adalah Provinsi Papua. Bentuk pembangunan di Provinsi Papua adalah pemekaran daerah otonom baru (DOB). Pembentukan daerah otonom baru mendorong pembangunan di daerah pemekaran, khususnya di perkotaan. Kota yang semakin berkembang dapat memicu arus urbanisasi sehingga jumlah penduduk semakin meningkat. Pertambahan jumlah penduduk mempengaruhi parameter iklim khususnya suhu udara. Suhu diperkirakan akan meningkat akibat bertambahnya jumlah penduduk perkotaan dan ketidakseimbangan energi yang masuk dan keluar bumi. Penelitian ini bertujuan untuk mengetahui pengaruh jumlah penduduk terhadap variasi suhu di Kabupaten Nabire dan Paniai. Data yang digunakan adalah data suhu rata-rata, minimum, dan maksimum tahunan di Stasiun Meteorologi Nabire dan Paniai. Data ditampilkan dalam bentuk grafik, dan korelasinya dihitung untuk dianalisis secara deskriptif. Hasil penelitian menunjukkan adanya korelasi yang kuat antara pertumbuhan penduduk dengan peningkatan suhu rata-rata dan minimum rata-rata. Sedangkan rata-rata suhu maksimum mempunyai hubungan yang lemah terhadap pertumbuhan penduduk.

Sumatran Admiral Vanessa samani (Hagen, 1895) (Lepidoptera: Nymphalidae) is a butterfly endemic to Sumatra, and can only be found in the Karo Highlands (North Sumatra) and Kerinci Mountain (southwestern Sumatra). In this paper, we report two additional records of V. samani from the Aceh Province in northern Sumatra, and the Jambul Highlands of South Sumatra. These records significantly extend the range of distribution of this rare Sumatran highland species. We also report three plants presumed to be the host plants of V. samani in Sumatra: Boehmeria sp., Smilax sp. (Smilax leucophylla) and Anaphalis sp. (Anaphalis longifolia).

Throughout Indonesia, more than a hundred million ha of degraded forest and lands are still to be rehabilitated. High-quality tree seedlings are a key component of landscape restoration. The limited supply of quality seeds has been an obstacle so far. C. inophyllum is a tropical tree species that grow well under harsh environmental conditions. It can be used as an alternative tree species for degraded land rehabilitation. We present an efficient and reproducible protocol for improving seed quality with exogenous NAA hormones. The Murashige and Skoog (MS) medium was supplemented with NAA hormones (0 mg/l, 1 mg/l, 2 mg/l, and 3 mg/l of NAA) for observation of the influence of the exogenous NAA on seeds germination in micro-environment controlled. After seven weeks of incubation in axenic culture, the highest concentration of NAA (3 mg/l) showed the fastest average seed-breaking time of C. inophyllum (2.0 weeks), After three weeks, the roots were nearly five times longer (4.9 ± 0.1 cm) than the control (1.1± 0.1 cm), and the shoots were nearly three times longer (4.9 ± 0.1 cm) than the control (1.1± 0.1 cm). This research needs to be tested on a larger scale of cultivation.Di seluruh Indonesia, lebih dari seratus juta ha hutan dan lahan terdegradasi masih harus direhabilitasi. Bibit pohon berkualitas tinggi adalah komponen kunci dari restorasi lanskap. Terbatasnya pasokan benih berkualitas menjadi kendala selama ini. C. inophyllum adalah spesies pohon tropis yang tumbuh dengan baik di bawah kondisi lingkungan yang keras. Ini dapat digunakan sebagai jenis pohon alternatif untuk rehabilitasi lahan terdegradasi. Kami menyajikan protokol yang efisien dan dapat direproduksi untuk meningkatkan kualitas benih dengan hormon NAA eksogen. Media Murashige dan Skoog (MS) dilengkapi dengan hormon NAA (0 mg/l, 1 mg/l, 2 mg/l, dan 3 mg/l NAA) untuk pengamatan pengaruh NAA eksogen terhadap perkecambahan biji di lingkungan mikro dikendalikan. Setelah tujuh minggu inkubasi dalam kultur axenic, konsentrasi NAA tertinggi (3 mg/l) menunjukkan rata-rata waktu pemecahan benih tercepat C. inophyllum (2,0 minggu), Setelah tiga minggu, akar hampir lima kali lebih panjang (4,9 ± 0,1 cm) dari kontrol (1,1± 0,1 cm), dan tunas hampir tiga kali lebih panjang (4,9 ± 0,1 cm) dari kontrol (1,1± 0,1 cm). Penelitian ini perlu diuji pada skala budidaya yang lebih besar.

The research objective is to find out genetic variation, estimated heritability value and the expected genetic gain of Samama [Anthocephalus macrophyllus (Roxb.) Havil.] on variation in stem diameter and plant height as superior seed producers. The research was conducted in Uraur Village, West Seram Regency, Maluku Province. The trials consisted of 80 families. All of the trials were laid out in randomized complete block designs (RCBD), 4-trees plots with 4 replications (blocks) at spacing of 5mÃ—2m. Data collection was carried out for 2 months (February to March 2020) and was focused on observing growth variations and genetic parameters in the progeny trial block at 4 years of age including plant height and diameter at breast height. The results of this study indicate that there are variations in growth, where the Anova test results show very significant differences in the plant height parameters namely Family (F = 3.417 p 0.01), Block (F = 437.465 p 0.01) and Family and Block Interactions (F = 3.351 p 0.01). The stem diameter parameters also showed very significant differences, namely Family (F = 2.785 p 0.01), Block (F = 353.095 p 0.01) and Family and Block Interaction (F = 2.611 p 0.01). The value of family heritability and individual heritability on plant height characters belonged to a high category with a family heritability value of 0.7213 and individual heritability value of 0.8811, while the stem diameter character for individual heritability was high with a value of 0.4406 but family heritability was moderate with value of 0.5204. The value of genetic correlation was high and positive and generally shows a greater value than the phenotypic correlation. Genetic correlation values ranged from 0.967 while phenotypic correlation values ranged from 0.8944. The highest selection priority was found in the height of the stem with a weight constant of 0.239. Predicted expected genetic gain was 3.0% for diameter parameter and 3.2% for height parameter.Objektif dari penelitian ini adalah menemukan variasi genetik, taksiran nilai heritabilitas serta peluang perolehan expected genetic gain tanaman Samama [Anthocephalus macrophyllus (Roxb.)

This study uses a Completely Randomized Design experimental method (CRD) consisting of three treatments with a range of 5 days, 10 days and 15 days, with each treatment uses three insect specimens. The treatments in this study were; P1 (200 mg ash + 200 ml distilled water), P2 (70% alcohol), and P0 (control). To observe the changes in texture, aroma and color in the inspect specimens, 50 panelists were engaged, who were aged between 17-30 years, that were not color blind and/or reporting any ill health at the time of sampling. Panelists observed the specimens for texture, aroma and color. Resulting data was analyzed using t test, frequency tabulation, histogram data and normality test. The texture testing treatments yielded tcount = 0.02521 (p 0.05) showing no significance between the coconut midrib ash and alcohol preserved samples, with the Ho accepted, so there is no difference in the texture of insect specimens preserved in either coconut midrib ash or alcohol. The aroma test resulted in tcount = 0.00908 (p 0.05) showing again there was no significant difference between insect specimens preserved in coconut midrib ash and alcohol. Thus, the Ho can be accepted, with no difference in the aroma of insect specimens preserved in coconut midrib ash or with alcohol. The color test resulted in a tcount = 0.05635 (p 0.05), giving a insignificant result between insect specimens preserved in coconut midrib ash or alcohol. Thus, the Ho can be accepted, and there is no difference in color of insect specimens preserved with coconut midrib ash or those preserved with alcohol. From the overall results and analysis, we can conclude there is no difference in the quality insect specimens preserved either by coconut midrib ash and alcohol for a maximum 15 days. Penelitian ini menggunakan metode eksperimen rancangan acak lengkap (RAL) yang terdiri dari tiga perlakuan dengan kisaran lama waktu 5 hari, 10 hari, dan 15 hari. Setiap satuan percobaan menggunakan tiga spesimen serangga, perlakuan dalam penelitian ini meliputi P1(200 mg abu + 200 ml aquades), P2 (alkohol 70%), dan P0(kontrol). Parameter yang diamati mengenai tekstur, aroma dan warna. Untuk mengamati perubahan tekstur, aroma dan warna yang terjadi, dilakukan oleh 50 orang panelis yang berusia antara 17-30 tahun dengan kriteria tidak buta warna dan tidak sedang dalam keadaan sakit. Data yang diperoleh dianalisis dengan menggunakan uji t, tabulasi frekuensi, data histogram dan uji normalitas. Berdasarkan hasil penelitian, pengujian tekstur menghasilkan nilai thitung = 0,02521 (p 0,05), diperoleh hasil yang tidak berbeda secara signifikan antara perlakuan dengan abu pelepah kelapa dan alkohol terhadap tekstur spesimen serangga. Dengan demikian dapat disimpulkan bahwa tidak terdapat perbedaan tekstur spesimen serangga yang diawetkan dengan abu pelepah kelapa dengan yang diawetkan dengan alkohol. Pengujian aroma menghasilkan nilai thitung= 0,00908 (p 0,05), diperoleh hasil tidak berbeda secara signifikan antara perlakuan dengan abu pelepah kelapa dan perlakuan dengan alkohol. Dengan demikian dapat disimpulkan bahwa tidak terdapat perbedaan warna spesimen serangga antara yang diawetkan dengan abu pelepah kelapa dengan yang diawetkan dengan alkohol. Dari hasil pengamatan dapat disimpulkan bahwa tidak ada perbedaan kualitas antara specimen serangga yang diawetkan dengan abu pelepah kelapa dengan yang diawertkan dengan alcohol dalam waktu maksimum 15 hari.
