Penelitian identifikasi tumbuhan berkhasiat obat di Hutan Lindung Wehea Kabupaten Kutai Timur bertujuan untuk mendapatkan informasi mengenai jenis-jenis tumbuhan obat dan pemanfaatan oleh masyarakat lokal di Hutan Lindung Wehea. Metode penelitian yaitu eksplorasi dan wawancara yang dilakukan dengan mencari nama ilmiah dan nama daerah (Dayak Wehea). Berdasarkan hasil wawancara dan identifikasi di peroleh 15 jenis tumbuhan obat tradisional yaitu dapat menyembuhkan 26 jenis macam penyakit. Bagian tumbuhan yang di gunakan dan dimanfaatkan untuk obat tradisional yaitu produk obat-obatan yang diolah secara tradisional berdasarkan resep ataupun kepercayaan dan kebiasaan setempat baik itu bersifat supranatural ataupun pengetahuan secara tradisional. Bahan yang di gunakan dalam pengelolahan obat tradisional. akar, buah, daun, tunas, biji dan rimpang. Masyarakat Dayak Wehea memiliki pengetahuan tradisional berdasarkan pengalaman hidup mengenai khasiat dan cara pengelolaan serta penggunaan tumbuh-tumbuhan yang dapat di manfaatkan sebagai obat tradisional. Pemanfaatan tumbuhan berkhasiat obat tersebut di wariskan turun temurun secara lisan sejak dari leluhurnya (nenek moyang). Agar pengetahuan mengenai pemanfaatan tumbuhan hutan berkhasiat obat yang dimiliki suku dayak Wehea tidak punah, dapat diwariskan maka perlu diteliti serta di perdalam secara ilmiah, maka perlu dilakukan pendokumentasian serta penelitian lebih lanjut mengenai kandungan yang terdapat pada tumbuhan obat yang biasa dimanfaatkan masyarakat tersebut, serta cara membudidayakan karena beberapa jenis tumbuhan sudah jarang dijumpai di sekitar kawasan Hutan Lindung Wehea.

Forests, traditional gardens and green spaces play an important role in regulating the water flow of an area. Along with the high demand for land in Bali for agriculture and tourism, many forest areas have been converted into hotels and settlements. Forest conversion has caused many problems such as erosion, soil fertility decreased, flora fauna extinction, floods, drought, global warming and the disturbing watershed, especially rivers for springs. The purpose of this study is the development of watershed conservation in Bali based on traditional agroforestry. The method that used is vegetation analysis. Calculation of the erosion amount using the USLE formula. Sampling was done by ten plots. The results showed that traditional agroforestry vegetation consisted of vertical and horizontal structures. The characteristic of traditional agroforestry is that dominant plants are distributed irregularly, thus creating a miniature structure like a forest. The vertical structure consists of trees, horizontal structure filled with species of garden plants and agriculture. Trees have roots spread intensively in the soil and reduce nutrient leaching. Land cover by vegetation protects the soil and erosion. The agroforestry has a role as an act of soil and water conservation. Traditional agroforestry land cover has a relatively low C coefficient (0.05-0.25) compared to other lands. The level of erosion hazard is low and moderate. Average erosion value of 55.01 t.ha-1.yr-1. This indicates that traditional agroforestry makes the soil have a higher ability to absorb water, thereby reducing surface runoff. Likewise, organic material that improves the water content capacity. In addition, water quality can be improved through the humus filter function. During a long dry season, there is a drought due to low rainfall, but rivers and springs were able to supply water for the peoples daily needs. This condition occurs because of the tree retentions in traditional gardens. Conservation actions need to be taken, namely maintaining trees vegetation, increasing reforestation, bench terraces use, mounds and mulch use. This condition also places traditional agroforestry as a sustainable land management system.

Batur Forest is a volcanic area that was an ex-volcanic eruption. Efforts to rehabilitate forests with critical land were by planting Eucalyptus urophylla. The aim of the study was to examine the adaptation of Eucalyptus urophylla species in critical areas of former volcanic eruptions that were dominated by hard rocks. The research was done for a year (2019-2020). The method used was a species test with a permanent block plot design from 4 age levels, 1 year, 5 years, 10 years, and 15 years. The study results showed growth of 1.02 cm in diameter and 1.10 m in height (1 year), 6.50 cm in diameter and 11.00 m in height (5 years), 13.25 cm in diameter and 18.40 m in height (10 years), and a diameter of 20.48 cm and a height of 23.00 m (15 years). Eucalyptus urophylla experienced the best tree diameter growth after 10 years old and on the contrary experienced a decrease in height. The Eucalyptus urophylla level of adaptation and suitability of volcanic soils with low fertility and rocky soil is a recommendation to increase the quantity of this species of planting. So that the forest succession from rocky thickets to tree vegetation is faster than natural processes. Eucalyptus urophylla species is one of the flora that makes up the savanna forest ecosystem and volcanic critical land in eastern Indonesia.

Bali Province is one of the local mango producers, namely Wani fruit. Wani fruit (Mangifera caesia) is a local Balinese fruit that has the potential to be developed. Wani fruit production in Bali has decreased due to fewer trees in community gardens. This study aims to determine the suitability of land for wani fruit plants on the slopes of Mount Batur Kintamani. Evaluation of land based on agroecological zones includes slope, drainage, humidity and temperature. Sampling used composite sampling based on agroecological zones and data analysis using descriptive and comparative methods. The results of research on the suitability of Wani fruit land in Kintamani show three classes, namely moderately suitable (CS), marginally suitable (SM), and not suitable (TS) with the main limiting factors being slope, texture, temperature, effective depth and rainfall. Based on the results of research on the Kintamani area, Mount Batur is suitable for the development of Wani Fruit in Bali. Primarily for Horticultural and Conservation purposes for the protection of local species. Based on agroecological zones, the land area in the Kintamani Bali area that can be developed for Wani fruit plants are zones I, II and III with an area of 21,476 Ha, which is 58.53% of the area of Kintamani. The distribution of agroecological zones suitable for the development of Wani fruit in zone I and II land units is predominantly spread in residential plain areas, and land units in zone III are spread in hilly areas.
