The increasing need for forest resources and cultivated land requires a solution in forest management to realize sustainable land use. Smart agroforestry (SAF) is a set of agriculture and silviculture knowledge and practices that is aimed at not only increasing profits and resilience for farmers but also improving environmental parameters, including climate change mitigation and adaptation, biodiversity enhancement, and soil and water conservation, while assuring sustainable landscape management. SAF, a solution for land management systems to reduce the rate of deforestation, is a smart effort to overcome the food crisis and mitigate climate change that is prospectively applied mainly in the social forestry area. Optimized forest land utilization could be achieved by implementing SAF and applying silvicultural and crop cultivation techniques to optimize productivity and meet sustainability and adaptability goals. This paper reviews the existing conditions, opportunities, and challenges in the mainstreaming of SAF in social forestry implementation to support the Sustainable Development Goals in Indonesia. Mainstreaming SAF should include policy innovation and regulation implementation, the use of appropriate technology, and compromises or trade-offs among benefits, risks, and resources. SAF is a strategy to revive the rural economy and community prosperity through the optimal use of local resources as well as a form of smart landscape and land-use management that has significant roles in soil and water conservation, bioenergy, climate change responses, and enhanced biodiversity conservation.

ManglietiaglaucaManglid ( BI) merupakan tanaman andalan Jawa Barat, Indonesia, karena cepat tumbuh dan banyak kegunaannya, namun teknik pembibitan khususnya secara vegetatif belum dikuasai. Tujuan penelitian ini adalah mengetahui pengaruh 6 dosis hormon Rootone-F terhadap kemampuan hidup dan pertumbuhan stek pucuk manglid. Rancangan penelitian yang digunakan adalah (CRD) dengan 6 perlakuan yaitu kontrol (tanpa hormon), Rootone-F 50 ppm, 100 ppm, 200 ppm, 500 ppm dan dioles. Hasil penelitian menunjukkan bahwa pemberian Rootone-F 100 ppm menghasilkan jumlah tunas tertinggi dibanding perlakuan lain (peningkatan 55% terhadap kontrol), panjang akar tertinggi sebesar 8,85 cm (peningkatan 34,46% dibanding kontrol) dan jumlah akar terbanyak sebesar 6,75 buah (peningkatan 40,74% dibanding kontrol). Pada parameter persentase hidup pemberian Rootone-F dioles menghasilkan nilai tertinggi yaitu 22,68 % dan tidak berbeda nyata dengan pemberian Rootone-F 100 ppm (20,68%). ABSTRACT

Soil fertility in industrial forest plantation needs attention, because fertile soil make good growth and produce timber and others well. A study to get information on the effects of plantation of ABSTRAKPembangunan hutan tanaman industri perlu memperhatikan f aktor kesuburan tanah, karena tanah yang subur memungkinkan pohon tumbuh dan menghasilkan kayu serta produk lainnya dengan baik. Penelitian mengenai pengaruh penanaman jenis pohon hutan, seperti Agathis loranthifolia, Pinus oocarpa, Shorea platyclados, Alnus nepalensis, Toona sureni, Casuarina junghuhniana, Khaya anthotheca dan Acacia cassicarpa telah dilakukan pada tanah andosol di dataran tinggi Cikole, Jawa Barat. Pengambilan sampel tanah dilakukan di bawah tegakan yang telah berumur enam tahun pada 3 titik dan dicampur untuk dianalisa sifat kimia dan biologi tanahnya, sedangkan sifat fisik sampel diambil pada dua kedalaman O cm -15 cm dan 15 cm -30 cm dengan menggunakan ring sampel. Hasil penelitian menunjukkan bahwa pH tanah di bawah tegakan umumnya masam sama dengan kondisi awal, kecuali untuk jenis S. platyclados sangat masam. Kandungan bahan organik, unsur hara makro dan kapasitas tukar kation pada umumnya sama, sehingga penanaman jenis dapat menstabilkan kondisi tanah. Tekstur tanah setelah penanaman lempung liat berdebu, kecuali T. sureni yang menjadi liat, sedangkan pengaruhnya terhadap porositas, berat jenis dan air tersedia berpengaruh positif. Selain itu, penanaman dapat meningkatkan jurnlah mikroorganisme, jumlah fungi dan respirasi di dalam tanah yang berdampak positif terhadap kesuburan tanah.Kata kunci: Kesuburan tanah, penanaman, pohon hutan, tanah andosol 155

Climate change has shortened the rainy season compared to the dry season in North Sulawesi. The El Nino phenomenon occurred in 2015 had an impact on the death of clove plants due to drought. Drought stress testing on several types of forestry plants in the North Sulawesi area is a matter that needs to be done in line with these conditions. Development of cempaka wasian (Magnolia tsiampaca (Miq.) Dandy), nantu (Palaquium obtusifolium Burck), and mahoni (Swietenia macrophylla King) plantations have been carried out by communities in North Sulawesi for a long time and have very good prospects. The research was done by conducting a simulation test at seedling level with treatment to be tested on volume and interval of watering. The watering volume consists of 3 levels, i.e. 100%, 50%, and 25% watering of the field capacity, while the watering intervals included once-daily, 3-day and 5-day watering once for 18 weeks. The results showed that nantu species has better resistance to drought stress conditions compared with mahogany and cempaka wasian.

Endophytic fungi is a group fungi that can be developed as a biological control agent. of endophytic fungi of Potency for agricultural crop has been discovered widely rare for forest trees The study was conducted to find out the , but still. antagonistic groups agains pathogen Fusarium sp. Fusarium is a casual agent of dumping-off on sengon tree. The highest average of inhibition after seven day incubation shown by Trichoderma harzianum Bio1999, was s was 46.36% followed by isolates of Aspergillus sp.

The objective of this research was to find out the transplanting media which is able to promote the best growth and quality of Manglieta glauca BI seedling. The experiment was conducted at the nursery of

In the planting program of lamtoro (Leucaena leucocephala), healthy and vigorous seedlings are needed, therefore, it is necessary to apply fertilizer at the nursery stage. The purpose of this study was to determine the effect of tofu's liquid waste and cow's urine on the growth of lamtoro seedlings at aged 6 weeks until 14 weeks. The treatments consisted of control, tofu’s liquid waste (30% and 40%), and cow’s urine (50%, 60% and 70%). Treatment was given every 2 weeks. Parameters observed were height, diameter, number of leaves, biomass, toughness, shoot root ratio, seedling quality index and chlorophyll content. The results showed that 30% and 40% of tofu’s liquid waste had a significant effect on increasing the height growth at 6 weeks and 8 weeks old seedling. The 70% cow’s urine has a significant effect on increasing the height growth at 6 weeks until 12 weeks old seedling. The 60% cow’s urine had a significant effect on increasing the number of leaves.
