Abstract

Shoreapinanga Scheff.   is a major tropical plant species which has an important  economic  value not  only for timber,  but also as illipe nut  (called tengkawang  in local  name) production.   This species   is suggested   for  land  rehabilitation    and  forest  conservation.    In rehabilitation   action, S. pi11a11ga is usually   planted   on the poor  and degraded  area.   Application   of  chemical  fertilizer and compost  is used to increase  the survival  and growth  of  the  seedlings.  Excessive chemical fertilizer  input  to soil, however,  may cause  negative  effect on  soil,  plant  and  environment. Conversely,  compost  may improve soil porosity, soil aggregate,  water absorption   and soil fertility. The objective  of  the study  was  to examine  effect  of  planting  media  on growth  of  S. pinanga  seedlings. Complete  randomized  design has been arranged with 5 treatments,  e.g. soil mixed with husk  (at the proportion   of  1:1), soil mixed with acacia compost  (1:1),   soil mixed with charcoal of  rice husk (1:1)   and soil mixed with humic acid (1:1).    Another  treatment  was  soil alone  used as control.   The  result showed that  growth  of  both  stem  height   and  diameter,  and  index  of seedling  quality  were affected  significantly   by planting  media.    The mixture  of  soil and  acacia compost  (1 :1)  was the best  planting media for the growth  of S. pinanga seedlings,  which resulted in the growth  of height  (24.19   cm) and stem diameter  (0.246 cm).  Meanwhile, soil mixed with rice husk charcoal (1:1)  gave the best result to the index of  seedling quality (ISQ = 1.34)   and total dry weight (TOW=   15.93  g).

Abstract

ABSTRAKCagar Alam Telaga Ranjeng (CATR) di Kabupaten Brebes, Jawa Tengah terletak di lereng Gunung Slamet dan dikelilingi oleh pemukiman dan Perkebunan Teh Kaligua. Cagar Alam ini mempunyai telaga sebagai penangkap air dan keanekaragaman jenis flora yang mempunyai peranan dalam melestarikan fungsi telaga tersebut. Tujuan penelitian ini adalah untuk mendapatkan informasi berbagai tumbuhan termasuk semak, anggrek, dan pohon di dataran tinggi tropis di wilayah CATR. Pengumpulan data dilakukan dengan membuat plot-plot pengamatan vegetasi. Data yang terkumpul dianalisis secara deskriptif-kuantitatif menggunakan Indeks Nilai Penting (INP). Hasil penelitian menunjukkan bahwa Brucea javanica (L.) Merr. merupakan jenis dominan (INP = 27,50 %) pada tingkat pohon berdiameter < 50 cm. Pinanga coronata Blume merupakan jenis dominan pada tingkat pancang (92,99 %), disusul Antidesma tetrandrum (24,73 %) dan Cyathea latebrosa (Wallich ex W. J. Hooker) Copeland (14,73). A. tetrandrum juga merupakan jenis dominan kedua pada tingkat pohon. Tingkat semai didominasi oleh Cyrtandra sp.. Keanekaragaman jenis tumbuhan pada tingkat pancang dapat menjamin kelestarian hutan CATR di masa mendatang, termasuk dalam konservasi flora dan fauna pada ekosistem hutan Gunung Slamet.

Abstract

Problem yang dihadapi di jalan sarad dalam pemanenan kayu adalah pemadatan tanah, erosi yang tinggi, me - nurunnya kesuburan tanah, miskinnya cendawan mikoriza dan kurangnya anakan. Untuk meningkatkan pro - duktivitas hutan di jalan sarad, maka diperlukan upaya pemulihan antara lain dengan penanaman pengayaan intensif dan cara lain yang dapat untuk mengurangi laju erosi, meningkatkan kesuburan tanah di jalan sarad dengan menerapkan lubang resapan biopori (LRB) dan cross drain (Cd). Tujuan penelitian ini adalah untuk mendapatkan informasi tentang pemanfaatan LRB  dan Cd  dalam penanaman pengayaan intensif untuk peningkatan produktifitas jalan sarad di hutan alam bekas tebangan. Lokasi penelitian diberi ijin usaha pemanfaatan hasil hutan kayu-hutan alam (IUPHHK-HA) pada hutan produksi Kalimantan Barat selama satu tahun. Rancangan penelitian adalah rancangan acak kelompok pola faktorial 2 x 2 dengan ulangan tiga kali. Faktor pertama yaitu LRB dan faktor kedua yaitu cross drain.  Hasil penelitian menunjukkan bahwa interaksi perlakuan LRB dan cross drain  memberi pengaruh yang nyata bagi pertumbuhan tinggi tanaman umur satu tahun Shorea leprosula dan Shorea parvifolia sedangkan untuk pertumbuhan diameternya tidak berpengaruh nyata. Perlakuan cross drain dapat meningkatkan serapan hara P, K, C organik di S. leprosula dan hanya serapan P dan C-organik di S. parvifolia.

Abstract

Ganitri (Elaeocarpus ganitrus Roxb) is a fast-growing tree species that is widely found in Indonesia, Malaysia, Myanmar, and Thailand. Ganitri seedlings’ generative propagation takes a long time because the seed coat is very hard, causing difficulty to germinate, therefore it is conducted vegetatively using stem and shoot cuttings with hormone treatment. The research objective was to obtain growth response of shoot cuttings and ganitri stem cuttings to hormone administration. The research was conducted in Silviculture greenhouse at Center for Standardization of Instruments for Sustainable Forest Management in Bogor. It used a Completely Randomized Design with a factorial pattern consisting of 2 factors. The first factor is cutting material: shoot cuttings and stem cuttings. The second factor is phytohormones: Rootone-F and coconut water. The results showed shoot cuttings with Rootone-F treatment gave the best growth compared to other treatment combinations. This was indicated by percent growing cuttings, percent rooted cuttings, root length, shoot wet weight, root wet weight, shoot dry weight and root dry weight which were higher with values of 63.33%, 53.0%, 8.10 cm, 2.92 grams, 0.28 grams, 1.33 grams, and 0.21 grams respectively. Thus, shoot cuttings survival with Rotoone-F hormone had a higher result than stem cuttings, reaching 63.33%.

Abstract

Podocarpus blumei is a slow-growing coniferous tree species belonging to the Podocarpaceae family, widely utilized for timber, handicrafts, and traditional medicine in Indonesia. However, its propagation remains limited due to seed dormancy and low germination rates. This study aimed to determine the most effective combination of seed dormancy-breaking techniques and wood vinegar concentrations to optimize seed germination and early seedling growth. The experiment was conducted using a completely randomized design with factorial treatments involving different dormancy-breaking methods—scarification, soaking in coconut water, and hot water—and variations in planting media (soil, cocopeat, and husk charcoal). Subsequent seedling treatments involved applying wood vinegar at four concentrations (0%, 0.1%, 0.2%, and 0.3%) for eleven months. Results showed that P. blumei seeds had an average moisture content of 40.14%, classifying them as recalcitrant. Among the dormancy-breaking treatments, scarification produced the highest germination rate (90%), maximum growth potential (92%), and fastest germination period (51 days) in soil–cocopeat–husk charcoal media. Application of 0.2% wood vinegar significantly increased stem diameter (0.8 mm), leaf number (19), and biomass accumulation, indicating enhanced physiological activity. In contrast, higher concentrations (≥0.3%) did not further improve seedling performance. The findings demonstrate that integrating mechanical scarification and moderate wood vinegar concentration (0.2%) effectively enhances the germination and early vigor of P. blumei seedlings. This study provides a practical propagation approach for conserving and sustainably managing Podocarpus blumei populations, contributing to improved silvicultural practices for native forest species in Indonesia.
