“…glauca is one of many recommended plants for land restoration due to its leaf photosynthetic related traits, including total chlorophyll, leaf moisture, leaf weight, and leaf area ( Ahmad, Setiadi & Widyatmoko, 2013 ). This species can reach maturity in under 10 years, and thus belongs to the fast-growing tree species category ( Sudomo, Rachman & Mindawati, 2010 ). In 2009, M. sumatrana var.…”

Background Essential oils are natural products of aromatic plants with numerous uses. Essential oils have been traded worldwide and utilized in various industries. Indonesia is the sixth largest essential oil producing country, but land degradation is a risk to the continuing extraction and utilization of natural products. Production of essential oil plants on degraded lands is a potential strategy to mitigate this risk. This study aimed to identify degraded lands in Indonesia that could be suitable habitats for five wild native essential oil producing plants, namely Acronychia pedunculata (L.) Miq., Baeckea frutescens L., Cynometra cauliflora L., Magnolia montana (Blume) Figlar, and Magnolia sumatrana var. glauca (Blume) Figlar & Noot using various species distribution models. Methods The habitat suitability of these species was predicted by comparing ten species distribution models, including Bioclim, classification and regression trees (CART), flexible discriminant analysis (FDA), Maxlike, boosted regression trees (BRT), multivariate adaptive regression splines (MARS), generalized linear models (GLM), Ranger, support vector machine (SVM), and Random Forests (RF). Bioclimatic, topographic and soil variables were used as the predictors of the model habitat suitability. The models were evaluated according to their AUC and TSS metrics. Model selection was based on ranking performance. The total suitable area for five native essential oil producing plants in Indonesia’s degraded lands was derived by overlaying the models with degraded land locations. Results The habitat suitability model for these species was well predicted with an AUC value >0.8 and a TSS value >0.7. The most important predictor variables affecting the habitat suitability of these species are mean temperature of wettest quarter, precipitation seasonality, precipitation of warmest quarter, precipitation of coldest quarter, cation exchange capacity, nitrogen, sand, and soil organic carbon. C. cauliflora has the largest predicted suitable area, followed by M. montana, B. frutescens, M. sumatrana var. glauca, and A. pedunculata. The overlapping area between predictive habitat suitability and degraded lands indicates that the majority of degraded lands in Indonesia’s forest areas are suitable for those species. Conclusion The degraded lands predicted as suitable habitats for five native essential oil producing plants were widely spread throughout Indonesia, mostly in its main islands. These findings can be used by the Indonesian Government for evaluating policies for degraded land utilization and restorations that can enhance the lands’ productivity.

“…The M3 media also resulted from the highest average yield of D. polyphylla seedling quality index (DQI) compared to other growing media. According to Sudomo et al (2010), a better seedling quality index will increase the chances of successful planting in the field. The M3 media produces the best quality seedlings because compost addition improves the characteristics of degraded peat soil.…”

The success of peat swamp ecosystem restoration needs to be supported by the supply of good quality native plant species, one of which is influenced by the growing media. This study aimed to evaluate the effect of cocopeat, compost, and biochar as a mixture of peat media on the growth of Dyera polyphylla and Shorea balangeran seedlings in a greenhouse for six months. The experiment was carried out using a completely randomized design with one factor, growing media (100% peat as M1 (control); 70% peat + 30% cocopeat as M2; 70% peat + 30% compost as M3; and 70% peat + biochar 30% as M4). The survival rate of both types of seedlings in all growing media treatments was 100%. Dickson Quality Index (DQI) of D. polyphylla seedlings on M1, M2, M3, and M4 was 0.32, 0.29, 0.46, and 0.31, respectively, and for S. balangeran was 0.15, 0.10, 0.09, and 0.12, respectively. Adding cocopeat, compost, and biochar could increase the nutrient content of peat media. The growing media with the best quality for D. polyphylla was M3, while for S. balangeran was M1.

Media pembibitan merupakan faktor eksternal yang juga menentukan pertumbuhan bibit tanaman. Penelitian ini dilakukan untuk menganalisis kandungan N,P, K, porosita,s dan pertumbuhan bibit sengon Paraserianthes falcataria (L) Nielsen pada 5 macam media pembibitan. Media pembibitan dibuat dari tanah ultisol dicampur sekam padi atau serbuk gergaji dengan takaran berbeda lalu diinkubasi selama 30 hari. Hasil analisis kandungan N total media M1 yaitu 0.18% (kategori rendah); media M2, M3, M4 dan M5, berkisar antara 0.20-0.50% (kategori sedang). Kandungan P media M1 yaitu 13.98 mg/kg (kategori rendah); media M2, M3, M4 dan M5, berkisar antara 26-35 mg/kg (kategori tinggi). Kandungan K semua media berkisar antara 9.68-18.63 me/100g (kategori tinggi). Porositas media M1= 52%; M2=66%; M3 = 84%; M4 = 75% dan M5 =71%. Hasil analisis pertumbuhan bibit sengon P. falcataria (L) Nielsen pada 5 media pembibitan yaitu: tinggi = 12.3-17.5 cm; diameter batang = 0.65-0.85 cm; jumlah daun = 110–140 helai dan panjang akar = 9.0–14.3 cm. Media pembibitan M3 berbahan tanah ultisol 50% dan sekam padi 50% menghasilkan kandungan N sedang, kandungan P dan K tinggi, porositas tertinggi, dan menghasilkan pertumbuhan bibit sengon P. falcataria (L) Nielsen terbaik.
