Meningkatnya akumulasi dan distribusi patogen, dipadukan dengan kondisi kelembapan dan suhu yang meningkat akibat perubahan iklim, dikhawatirkan akan mempercepat laju infeksi pada tanaman hutan. Hal ini dapat berakibat fatal bagi ekosistem hutan secara keseluruhan.

Meskipun beberapa patogen populasinya menurun karena kondisi inang yang justru menjadi kuat oleh pemanasan global.  Peran patogen sebagai agen pengganggu tanaman hutan akan meningkat dan memberikan dampak buruk pada ekosistem hutan. Akibatnya perannya sebagai agen pengganggu tanaman hutan akan meningkat Terdapat ratusan patogen, baik asli maupun pendatang, yang berinteraksi dengan ekosistem hutan tanaman.

Dengan mempertimbangkan bahwa perubahan iklim global akan terus terjadi termasuk juga di Indonesia serta perbedaan tingkat pengetahuan tentang fisiologi, siklus hidup, dan iklim yang mendukung perkembangan patogen, merupakan tantangan bagi ahli penyakit hutan, Hal tersebut akan meningkatkan risiko terjadinya outbreak penyakit hutan di Indonesia. Permasalahan outbreak penyakit hutan sangat kompleks dan perlu ditangani secara bersama- sama dengan melibatkan berbagai pihak terkait. Untuk itu di Indonesia, perlu diusulkan dibentuk “Tim Mitigasi Kesehatan Hutan IndonesiaTanaman” yang memiliki peran pengawasan yang efektif dan memiliki protokol pendeteksian serta alat yang memadai untuk memudahkan dilakukannya tindakan cepat dan tepat dalam menghadapi perubahan atau peningkatan dampak gangguan hutan. Hal tersebut disampaikan oleh Prof. Dr. Ir. Sri Rahayu, S.Hut., M.P., dalam pidato pengukuhan Guru Besarnya yang berjudul “Produktivitas dan Kelestarian Hutan Tanaman: Peran Patologi Hutan di Tengah Perubahan Iklim Global” pada hari Selasa (23/4) di Balai Senat Universitas Gadjah Mada.

Dalam pidatonya, Prof. Sri Rahayu juga menyampaikan dalam rangka untuk menjaga stabilitas dan ketahanan hutan tanaman, termasuk di dalamnya adalah HTI, maka antisipasi dan mitigasi yang dapat dilakukan dalam rangka mengadaptasi perubahan iklim adalah,

• Monitoring untuk membantu deteksi dini penyakit pohon, sehingga akan dapat berpotensi meningkatkan keberhasilan pengelolaan penyakit. Oleh karena itu, diperlukan pengawasan hutan yang berkelanjutan untuk mengetahui masalah kesehatan pohon yang ada;
• Peramalan Skenario perubahan iklim telah digunakan untuk meramalkan risiko beberapa penyakit pohon di masa depan. Namun, ketidakpastian yang ditimbulkan oleh peramalan harus diantisipasi. Peramalan dapat dikembangkan menggunakan model, analisis risiko, dan peringkat risiko. Model ini dapat digunakan untuk memproyeksikan potensi dampak penyakit hutan, memberikan wawasan tentang besaran dan arah perubahan penyakit, membantu memfokuskan kegiatan pemantauan, dan memberikan masukan untuk menejemen dalam melakukan evaluasi dan pengembangan strategi pengelolaan penyakit;
• Pengembangan Sistem Analisis dan Pemeringkatan Risiko Sistem ini dikembangkan melalui evaluasi data yang tersedia dan antisipasi perilaku patogen untuk memperkirakan dampaknya pada lingkungan baru dan untuk menentukan responsnya pada pengelolaan yang akan dilakukan;
• Pengembangan Strategi Perencanaan dan Mitigasi Strategi peningkatan kapasitas ekosistem untuk meningkatkan ketahanan ekologi sangat diperlukan. Penerapan intervensi silvikultur intensif yang tepat untuk meningkatkan kekuatan pohon 12 dan menurunkan dampak patogen berdasarkan skenario iklim yang diprediksi perlu difasilitasi dan dikembangkan. Di samping itu, program pemuliaan perlu dirancang dalam rangka meningkatkan toleransi dan ketahanan tumbuhan terhadap patogen dan stres lingkungan.

Pengukuhan Prof. Sri Rahayu sebagai Guru Besar dalam bidang Patologi Hutan merupakan momen spesial, tidak hanya karena bertepatan dengan ulang tahun beliau ke-59, tetapi juga karena beliau dikukuhkan bersama sang suami, Prof. Dr. Tata Wijayanta, S.H., M.Hum., dari Fakultas Hukum UGM, setelah penantian selama 10 tahun.

Dedikasi dan sumbangsih Prof. Sri Rahayu dalam bidang Patologi Hutan diharapkan dapat memberikan manfaat bagi kelestarian hutan dan ketahanan pangan di Indonesia. (Humas/FKT)

Abstract
Uncontrolled fires place considerable burdens on forest ecosystems, compromising ourability to meet conservation and restoration goals. A poor understanding of the impactsof fire on ecosystems and their biodiversity exacerbates this challenge, particularly intropical regions where few studies have applied consistent analytical techniques to exam-ine a broad range of ecological impacts over multiyear time frames. We compiled 16 yof data on ecosystem properties (17 variables) and biodiversity (21 variables) from atropical peatland in Indonesia to assess fire impacts and infer the potential for recovery.Burned forest experienced altered structural and microclimatic conditions, resulting ina proliferation of nonforest vegetation and erosion of forest ecosystem properties andbiodiversity. Compared to unburned forest, habitat structure, tree density, and canopycover deteriorated by 58 to 98%, while declines in species diversity and abundance weremost pronounced for trees, damselflies, and butterflies, particularly for forest specialistspecies. Tracking ecosystem property and biodiversity datasets over time revealed mostto be sensitive to recurrent high-intensity fires within the wider landscape. These mega-fires immediately compromised water quality and tree reproductive phenology, crashingcommercially valuable fish populations within 3 mo and driving a gradual decline inthreatened vertebrates over 9 mo. Burned forest remained structurally compromisedlong after a burn event, but vegetation showed some signs of recovery over a 12-y period.Our findings demonstrate that, if left uncontrolled, fire may be a pervasive threat to theecological functioning of tropical forests, underscoring the importance of fire preventionand long-term restoration efforts, as exemplified in Indonesia.

Abstract
Asoka (Saraca indica L.) branch wood was evaluated for its chemical composition, morphological features, kraft pulping behavior, and physical properties. The Asoka used in this study contained low amounts of cellulose and hemicellulose, but higher amounts of lignin and ash. It was found that the morphological indices of Asoka branch wood were mostly adequate for pulping and papermaking. The pulping of this wood was performed using chemi-mechanical pulping (CMP), conventional kraft pulping, and soda pulping processes under different conditions, i.e., active alkali and anthraquinone (AQ) addition. The results showed that alkaline pupling and CMP provided low screened yield values. Acceptable kappa numbers and reject levels were obtained at 22% active alkali of soda and kraft-AQ pulpings. CMP pulp showed higher brightness and screened yield than that of alkaline pulps. Alkaline pulpings of Asoka branch wood provided slightly different strength properties of paper sheets than those of CMP pulp. Based on the findings, it can be concluded that Asoka branch wood is more suitable as a raw material for mechanical pulping than it is for alkaline pulping.

Abstract
Passive acoustic monitoring is a promising tool for monitoring at-risk populations of vocal species, yet extracting relevant information from large acoustic datasets can be time- consuming, creating a bottleneck at the point of analysis. We adapted an open-source framework for deep learning in bioacoustics to automatically detect Bornean white-bearded gibbon (Hylobates albibarbis) “great call” vocalisations in a long-term acoustic dataset from a rainforest location in Borneo. We describe the steps involved in developing this solution, such as collecting audio recordings, developing training and testing datasets, training neural-network models, and evaluating model performance. Our best model performed at a satisfactory level (F score = 0.87), identifying 98% of the highest-quality calls from 90 hours of manually-annotated audio recordings. We also found no significant difference in the distribution of great call detections over time between the manual annotations and the model’s output, and greatly reduced analysis times when compared to a human observer. Future work should seek to apply our model to long-term acoustic datasets to understand spatiotemporal variations in H. albibarbis’ calling activity. With additional information, such as detection probability over distance, we demonstrate how our model could be used to monitor gibbon population density and spatial distribution on an unprecedented scale.

Abstract
Water is a basic need for all living things on earth. The existence of water on Earth cannot be separated from the hydrological cycle. The presence of vegetation has an impact on the water absorption process and protects the soil surface from the kinetic energy of rainwater. Vegetation measurements were carried out on plots measuring 8 m x 60 m. The measuring plot is made perpendicular to the contour direction or in the direction of the slope. Data processed with Ms. Excel continued with SExIFS software. Vegetation data was collected to create a profile diagram with horizontal and vertical projections as well as calculate the relative dominancy (DR), relative frequency (FR), and relative density (KR) to determine the important index (INP) value. The research results showed that the percentage of canopy cover varied from 33.13% in Tuk Umbul, followed by Sendang Tahunan and Sendang Ayu at 46.87% and 42.08%, then Sendang Mojo (74.17%) and the best is at the Salak Spring area (87.71%). The highest important index values are at teak (Tectona grandis), followed by Jabon (Neolamarckia cadamba), and Beringin (Ficus sp.).

Abstract
The aim of this study was to analyze the extractive composition of the wood and bark of cajuput (M. cajuputi subsp. cajuputi) to consider the end use material according to the characteristics of the its extractives. Results showed that the extractives properties of M. cajuputi, i.e. the contents of n-hexane, methanol, hot water extractives and total phenolic content (TPC), flavonoid content (TFC) and total polysaccharides (TSP) were 0.84 to 1.05%, 1.00 to 1.03% and 1.43 to 1.46%, and 19.2 to 38.7 and 23.2 to 27.3 mg GAE/g dried extract, 11.8 to 16.0 and 7.55 to 14.0 mg QE/g dried extract and 79.3 to 102.8 and 148.8 to 165.9 mg
Glu/g dried extract, respectively. Bark had higher extractive levels than wood. In addition, TPC and TSP in the bark were greater than in the wood parts, whereas the reverse trend was found in
TFC. The relatively high contents of TPC and TFC in the wood and bark suggest that their potential antioxidant properties. Based on the GC-MS analysis, the high content of
sterols-steroids (31.4%) and triterpenoids (21.9%) in the bark part will have potential in the field of pharmacology.

Abstract
Pinus merkusii is one of the most important timber species in Indonesia, the main product of which is its oleoresin. The objective of this study was to examine the effects of collection period (three periods, with 6-day observation each) on oleoresin yield in relation to two factors: growth sites of Pinus merkusii, which in the case of this study were East Banyumas, West Banyumas, and West Pekalongan Forest Management Units, and use of stimulants (sulfuric acid and ethephon mixtures, ETRAT, SR4, and no treatment). The average total oleoresin yield from a single tree or wound during the 18-day observation period was 110−185 g/tree for untreated trees and 159−442 g/tree for stimulant-treated trees. By analysis of variance, the interaction between each collection period (6-day observation period) and tree growing sites showed that the maximum average oleoresin yield for one hole was 109.32 g/tree measured in East Banyumas in the first collection period. Furthermore, the East Banyumas site consistently showed significantly the highest yield in each period. The interaction between the factors of stimulant and collection period (6day observation) resulted in the highest average oleoresin yield (121.86 g/tree) measured for trees treated with sulfuric acid (20%) and Ethephon (2%) mixtures in aqueous solution (v/v) treatment in the first collecting period. In West Pekalongan, the resin yield from trees treated with different treatments tended to be positively related to tree diameter. In addition, a positive correlation was found between resin yield and tree height or crown closure, while a negative correlation was found between resin yield and site elevation in trees treated with certain stimulants.

Abstract
Anthropogenic activities carried out by communities around forests in production forests, protected forests, and conservation forests have an impact on changes in the land cover of these areas. This impact is difficult to avoid because, on the other hand, production forests and protected forests are in direct contact with the lives of local communities. Changes in land cover have a significant impact on the contribution of Folu Net Sink, which is set by the government at 31.89% in 2030 with its efforts. This research aims to provide an overview of land cover changes that occurred in natural forests of the Eucalyptus urophylla type from 2002 to 2022. The method used in this research is a supervised/guided digital classification technique. Ground checks were also carried out in this research to match the accuracy of the image data with the actual conditions in the field. The research results show that changes in land cover in 2012 and 2017 were very extreme. Forest fires were the cause of changes in land cover during this period. Meanwhile, in 2002, 2007, and 2022, the land cover was still good, in a positive direction. The causes of changes in land cover are encroachment activities, encroachment, illegal logging, firewood theft, rice fields, forest fires, plantations, and farming. Forest preservation provides very high benefits for life on earth. Therefore, it is important to pay attention to the welfare of local communities so that they do not damage the forest, as well as increase the capacity to educate the community regarding zoning or blocks in conservation and protected forests. Apart from that, good forest management is needed to ensure forest sustainability in the future.
