"Repeated forest fires have high impact on species’ composition. Pioneer species colonize the burnt forest and develop widely up to 30 years after a fire but late-succession species regenerate gradually or even disappear owing to direct impact of fires or other ecological consequences related to fires. Forest restoration through assisted natural regeneration needs information about the state of species’ composition after fire. Species’ dominance is a species’ composition indicator used in this research, with additional information on species’ association and distribution patterns, to understand tree species’ composition after repeated fires. A 1.8-hectare plot divided into 10 x 10 m sub-plots was established in secondary forest in Samboja Research Forest, East Kalimantan. The plot sample was burnt in 1982/1983 and 1997/1998. All trees above 10 cm DBH were measured; leaf specimens were collected for species’ identification at the Herbarium Bogoriense, Cibinong, West Java. For comparison, we used 1981 data observed by the Indonesian Institute of Science, published by Kartawinata et al 2008. The Importance Value Index was used in the data analysis to express species’ dominance. A 2x2 matrix based on presence-absence of species for each sub-plot was used to analyse the association index among species. Variance and average value ratio of certain species present in each sub-plot was expressed in a dispersion index. A chi-square was used to test the significance of the association and dispersion index. Thirteen years after a second fire, pioneer species of Macaranga gigantea were most dominant, followed by Vernonia arborea, a sub-climax species. This indicated that the forest was in an early succession process. Pholidocarpus majadun was consistently dominant before and after the fire. We found 38 pairs of species significantly positively associated and 4801 pairs negatively associated. About 60% species’ association, both negatively and positively, occurred between ‘native species’ (species that exist befores burnt) and ‘non-native species’ (new comer species regenerated after burnt) in the plot sample. A non-native species, Vernonia arborea, associated negatively with the non-native species Tabernaemontana sphaerocarpa, and native species, Oncosperma horridum, Palaquium dasyphyllum and Endiandra rubescens. The distribution pattern of four native species—Artocarpus anisophyllus, Cananga odorata, Croton laevifolius and Macaranga gigantea—changed after repeated fires, from uniform to clumped."

"Latar Belakang: Pada proses regenerasi jaringan terjadi ketidakseimbangan antara kebutuhan oksigen dengan suplai oksigen yang menyebabkan jaringan mengalami hipoksia relatif. Keadaan hipoksia diduga memiliki peran penting dalam proses regenerasi jaringan. Pada penelitian ini, dianalisis ekspresi protein dan gen yang berperan mengatasi keadaan hipoksia (HIF-1α dan HIF-2α), protein yang berperan dalam suplai oksigen (Cygb), protein yang menstimulasi biogenesis mitokondria (PGC-1α) serta enzim yang mampu menangkal radikal bebas (MnSOD) pada regenerasi jaringan. Regenerasi jaringan ekor pada cecak rumah (Hemidactylus platyurus) digunakan sebagai model dalam penelitian ini, karena merupakan hewan yang paling dekat secara taksonomi dengan mamalia yang memiliki daya regenerasi tinggi, dibandingkan vertebrata lain dengan kemampuan sama. Diharapkan penelitian ini dapat menjadi model dalam mempelajari proses regenerasi dalam upaya pengembangan terapi penyembuhan luka. Metode: Penelitian bersifat eksperimental deskriptif menggunakan jaringan 30 ekor cecak hasil regenerasi pada hari ke 1; 3; 5; 8; 10; 13; 17; 21; 25; dan 30 setelah autotomi dengan 3 kali pengulangan pada setiap pengamatan. Cecak diperoleh dari lingkungan laboratorium Zoologi Puslit Biologi LIPI Cibinong. Analisis ekspresi gen dilakukan dengan metoda qRT-PCR; analisis ekspresi protein dinilai dengan metoda Western Blot dan imunohistokimia, serta dilakukan analisis struktur histologi jaringan dengan pewarnaan hematoksilin-eosin. Penelitian dilakukan di Laboratorium Departemen Biokimia & Biologi Molekuler FKUI; laboratorium Histologi FKUI, laboratorium PRVKP FKUI, dan laboratorium Patologi Anatomi FKH IPB. Penelitian dalam kurun waktu tahun 2015-2018. Hasil penelitian: Grafik pertumbuhan jaringan ekor cecak menghasilkan pola pertumbuhan yang lambat pada 13 hari pertama, pertumbuhan yang sangat cepat hari ke 13 sampai ke 21, dan kembali lambat sampai hari ke 30. Pada awal pertumbuhan, ekspresi HIF-1α dan HIF-2α tinggi menunjukkan jaringan dalam keadaan hipoksia. Tingginya ekspresi Cygb selama proses regenerasi jaringan dari awal hingga akhir pengamatan menunjukkan perannya untuk mengakomodasi oksigen selama proses regenerasi berlangsung. Ekspresi PGC-1α yang tinggi di awal proses dan tetap dipertahankan sampai akhir pengamatan berperan untuk mempertahankan agar energi untuk proses regenerasi dapat terpenuhi melalui biogenesis mitokondria. Tingginya ekspresi MnSOD dalam jaringan pada awal regenerasi diduga memiliki peranan yang berkaitan dengan netralisasi senyawa radikal dalam jaringan. Kesimpulan: HIF 1α, HIF 2α, Cygb, PGC 1α dan MnSOD masing-masing memiliki peran penting tersendiri dalam proses regenerasi jaringan.

Background: In tissue regeneration there is an imbalance between oxygen demand and supply causes the tissue to experience relative hypoxia. Hypoxia is thought to have an important role in the tissue regeneration. This research analyzed the expression of proteins and genes that play role in overcoming hypoxia (HIF-1α dan HIF-2α); the protein involved in oxygen supply (Cygb); the protein that stimulates mitochondrial biogenesis (PGC-1α); and the enzyme counteract free radicals (MnSOD). The regeneration of house gecko's tail (Hemidactylus platyurus) was used as a model in this research, because it is the taxonomically closest animal to mammals that have a high capability in regeneration, compared to other vertebrates with the same ability. Hence, this study might become a model in studying tissue regeneration as an effort in developing a wound healing treatment. Method: The research was performed in a descriptive experimental way, using 30 geckos, having undergone regeneration on day 1; 3; 5; 8; 10; 13; 17; 21; 25; and 30 after autotomy. The experiment used 3 repetitions for each observation. House geckos were obtained from the laboratory building of Zoology Research Center of Indonesian Institute of Sciences (LIPI) Cibinong and its surrounding area. The analysis for gene expression was performed using qRT-PCR method; the analysis for protein expression was undertaken using Western Blot method and immunohistochemistry. In addition to these, the structure analysis for the tissue histology was performed using Haematoxilyn and Eosin (H&E) staining method. The study was conducted in the Laboratory of the Department of Molecular Biochemistry & Biology FKUI; Laboratory of the Department of Histology FKUI; laboratory of the Institute of Human Virology & Cancer Biology FKUI; and laboratoty of Phatology Anatomy of Animal Medicine, Institute of Agriculture Bogor, in the year 2015-2018.Results: The graph for the growth of the gecko tail tissue exhibits a slow growth pattern for the first 13 days, followed by a very swift growth between day 13 to 21, returning to slow growth afterwards until day 30. In the early growth stage, the expression of HIF1α and HIF-2α were increased which showed the tissue was in hypoxia state. HIF protein regulates the contributing to the tissue regeneration process, leading to the increasing growth of tissue with the correlation values of r=-0,853 for HIF-1α; r=-0,75 The substantial expression of Cygb observed throughout the process of tissue regeneration indicates its role in accommodating oxygen in the regeneration process. The expression of PGC-1α was observed to be high in the early stages of the process and remain so until the process ends. This indicates its function in maintaining that sufficient energy provided by mitochondrial biogenesis is available for the regeneration process. The high level of MnSOD expression in the tissue in the early stage of regeneration is thought to relate to its role in neutralizing radicals inside the tissue. Conclusion: HIF 1α, HIF 2α, Cygb, PGC 1α and MnSOD have their own important roles in the tissue regeneration process."

"This volume focuses on the broad pattern of increasing biodiversity through time, and recurrent events of minor and major ecosphere reorganization. Intense scrutiny is devoted to the pattern of physical (including isotopic), sedimentary and biotic circumstances through the time intervals during which life crises occurred. These events affected terrestrial, lacustrine and estuarine ecosystems, locally and globally, but have affected continental shelf ecosystems and even deep ocean ecosystems. The pattern of these events is the backdrop against which modelling the pattern of future environmental change needs to be evaluated."

"Katalis merupakan doping suatu reaksi dengan maksud memperbesar kecepatan reaksi. Katalis terlibat dalam reaksi tetapi tidak mengalami perubahan kimiawi yang permanen sehingga pada akhir reaksi katalis akan dijumpai kembali dalam bentuk dan jumlah yang sama seperti sebelum reaksi.Namun katalis tidak dapat digunakan selamanya. Deaktivasinya aktivitas katalis diduga disebabkan karena terjadi penutupan pori oleh kokas (coke). Regenerasi merupakan proses yang dilakukan untuk menghilangkan kandungan kokas di dalam katalis. Siklus deaktivasi dan regenerasi katalis ini dapat melihat berapa lama masa aktif dari katalis. Siklus aktif katalis yang paling lama terjadi saat proses rentang waktu deaktivasi 3 jam dan suhu regenerasi 450oC. produk akhir siklus yang masih bisa terproduksi sebesar 1.9% Benzena, 0.9% Toluenea dan 0.7 % Xylene.Dari hasil siklus deaktivasi dan regenerasi katalis HZSM-5 dapat terlihat pula kemampuan shape selectivity dari katalis HZSM-5.

The catalyst is a reaction with the intention of doping increase the reaction rate. Catalyst in the reaction but not a permanent chemical change so that at the end of the catalytic reaction will be found back in shape and the same number as before the reaction. However, the catalyst can not be used forever. Deactivated catalyst activity alleged to be caused due to the closure of pores by coke. Regeneration is a process to eliminate the content of coke in the catalyst. In this case regeneration is using air resulting in oxidation reactions. Cycle Deactivation and regeneration of Catalyst can knowing how long active time from catalyst. Cycle active catalyst who longest active at process 3 hours deactivation and 450oC regeneration temperature. The last product who can still production at last cycle is 1.9 % Benzene, 0.9 % Toluene and 0.7 % Xylene. From the results cylcle deactivation and regeneration of catalyst HZSM-5 can we see shape selectivity from catalyst HZSM-5."
