“…Di sisi lain, budiaya sengon dalam skala besar di Indonesia, khususnya di Pulau Jawa menghadapi beberapa tantangan (kendala) secara ekologis, seperti terjadinya serangan organisme patogen (penyakit) yang dapat menurunkan produksi kayu sengon hingga 15 % -81 % (Baskorowati, 2020;Darwiati & Anggraeni, 2018). Penyakit yang dapat menyebabkan kerusakan pada sengon diantaranya, yaitu karat puru (Uromycladium falcatarium), damping-off (Rhizoctonia sp.…”

Hutan rakyat adalah hutan tanaman yang tumbuh di atas lahan milik rakyat atau masyarakat. Sengon (Falcataria moluccana) dan balsa (Ochroma pyramidale) merupakan jenis multi fungsi dan cepat tumbuh yang banyak dibudidayakan di Indonesia, khususnya di Pulau Jawa. Serangan penyakit hutan merupakan ancaman yang berpotensi mengganggu kegiatan budidaya kedua jenis ini, serta dapat merugikan secara ekologi, ekonomi, dan sosial. Pengenalan penyakit hutan merupakan kegiatan preventif yang sangat penting dalam pengelolaan penyakit hutan itu sendiri. Tujuan pengabdian pada masyarakat dalam “Program Dosen IPB Pulang Kampung” ini adalah sebagai upaya capacity building masyarakat sekitar hutan melalui penyuluhan, pelatihan, dan pendampingan terkait pengenalan (identifikasi) dan pengelolaan penyakit pada hutan tanaman yang ditujukan bagi para masyarakat petani hutan dan/atau pihak (stakeholder) terkait di Desa Ngancar, Kabupaten Kediri, Jawa Timur. Secara umum, program ini membantu meningkatkan pengetahuan dan pengalaman peserta dalam mengidentifikasi penyakit hutan tanaman, khususnya untuk jenis sengon dan balsa. Hal tersebut diindikasikan dari hasil penilaian dan evaluasi terhadap kuisioner (pre- dan post-test) para peserta pelatihan yang menunjukkan peningkatan, masing-masing, yaitu 7% (pelatihan Gelombang I) dan 9% (pelatihan Gelombang II). Community forests are forest plantations that grow on land owned by the people or community. Sengon (Falcataria moluccana) and balsa (Ochroma pyramidale) are multi-functional and fast-growing species that are widely cultivated in Indonesia, especially on the island of Java. Forest disease outbreaks are a potential threat that can disrupt the cultivation of these two species, and can cause ecological, economic, and social harm. The introduction of forest disease is a preventive action that is very important in managing of forest diseases. The aim of the community service in the “Program Dosen IPB Pulang Kampung” is to build the capacity of communities around the forest through counselling, training, and assistance related to the identification and management of diseases in forest plantations, targeting forest farmers and/or stakeholders in Ngancar Village, Kediri Regency, East Java. In general, this program helps to increase the knowledge and experience of participants in identifying forest diseases, specifically for sengon and balsa species. This is indicated by the results of the assessment and evaluation of questionnaires (pre- and post-tests) of the training participants, which showed an increase of 7% (Batch I) and 9% (Batch II).

“…Hasil observasi tersebut mengindikasikan bahwa beberapa famili asal Papua lebih toleran terhadap serangan penyakit karat tumor (Baskorowati, Susanto, et al, 2012). Hasil uji tingkat semai juga menunjukkan bahwa sengon asal Wamena lebih resisten dibanding asal Jawa (Baskorowati & Nurrohmah, 2011;Rahayu, 2007), Brumas (Malaysia), Timor Timur, Maluku dan Flores Timur (Rahayu, 2007).…”

This study aims to determine the provenance of sengon that is resistant / tolerant to tumor rust attack in Panjalu District, Ciamis Regency. The experimental design used in developing a resistance test plot was a completely randomized block / RCBD (Randomized Complete Block Design). There were 12 provenances used in this trial, consisting of 25 treeplot (5 x 5) from Papua, with 4 blocks as replications and spacing of 2 mx 3 m.. The results showed that provenance differences did not significantly affect all 2-year-old sengon growth parameters. The highest survival rate was achieved by Nifasi provenance (95%) and the lowest was achieved by Elaigama provenance, Hobikosi (67%). The average height ranges from 3.17 meters (Meagama) to 5.51 meters (Maidi, Nabire), while the average stem diameter ranges from 3.27 cm (Pyramid, Muai) to 6.72 cm (Maidi, Nabire) Up to 2 years old, there were 3 provenances of sengon from Wamena which were tolerant of tumor rust attack, namely from Waga-Waga, Holima and Hobikosi. Meanwhile, attacks on 9 other provenances were generally still in the low level, i.e. the highest Disease Incidence and disease severity were Wadap and, Menawi provenances by 20.8% and 43% respectively. These provenances need to be evaluated continuously to find out the provenances that are resistant to gall rust disease over one rotation period as genetic material for future sengon forest development.

“…Sengon yang berasal dari Wamena, sebaliknya, diketahui merupakan jenis sengon yang lebih tahan terhadap penyakit karat tumor, karena menunjukkan luas dan intensitas serangan yang lebih rendah (Baskorowati & Nurrohmah, 2011;Baskorowati, Susanto, & Charomaeni, 2012).

Sengon (Falcataria moluccana) is fast growing species mostly planted by farmers due to its high productivity. Sengon originating from Solomon Island has been known with the high productivity eventhough susceptible to gall rust attack; on the other hand, sengon originating from Wamena is known to be more tolerant to gall rust attack. There is no previous study in terms of stem xylem structures comparing sengon from those seed origins. Therefore, this study was undertaken to identify the differences in anatomical structure of sengon stem; and to compare the xylem cell based on proportions and dimensions of the stems between the two provenances. Six stem samples of tolerant Wamena provenance and six samples of susceptible Solomon provenance were used in this study. Samples were collected from progeny trial of sengon in Lumajang, Jawa Timur. The observations include the anatomical structures and vessel element, parenchyma apotracheal cell, parenchyma paratracheal cell, xylem fiber, fiber length, and fiber diameter. The result showed that there was no difference in terms of anatomical structures between sengon Wamena (tolerant) and Solomon (susceptible) stem in cross section, tangential and radial section of periderm, phloem, secondary xylem (vessel cell, xylem fiber, and parenchyma xylem) and pith. However, in one of susceptible stem sample, a black reaction zone on the secondary xylem was found. Analysis of variance showed that parenchyma paratracheal cell, apotracheal cell, number of xylem fibers, xylem fiber diameter and length were not significantly different between stem of sengon Wamena (tolerant) and Solomon (susceptible).
