Around 12.62% of watersheds in Indonesia are damaged and need restoration immediately to prevent floods, landslides, and other related disasters. This study aimed to evaluate the Wosi watershed and formulate conservation scenarios to improve its conditions. The data collection included hydrology (quantity, continuity, and water quality), land (critical land index, percentage of vegetation cover, and erosion index), socio-economic (population pressure, welfare level, existence, and regulations enforcement), building investment (city classification and water building value classification), and the use of space (protected areas and cultivation areas). The evaluation of carrying capacity used a scoring analysis. The scenarios formulation used the information on potential carrying capacity and conservation strategies. The results suggested that the carrying capacity of the Wosi watershed from 2016-2019 had fallen into "bad" and "very bad" categories. To improve these conditions, the government can assign the riparian areas as a government asset, build ponds and dikes in the flood-prone areas, apply small recharge pond (SRP) on the cacao plantations, and assign Wosi Rendani protected forest (HLWR) as an urban forest. The implementation of these conservation strategies will result in the improvement of (a) the carrying capacity of the Wosi watershed and (b) the status into the "good" category to support environmentally friendly development in Manokwari city.

The number of visitors to Kalibiru Nature Tourism Object in Kulon Progo Regency during weekends has exceeded its effective carrying capacity. Distributing the visitors on weekdays could become one of the solutions to prevent ecological damage. This research aimed at better understanding the relationship between visual landscape quality and the level of visitors’ experience in Kalibiru Nature Tourism Object, Kulon Progo Regency. Two independent surveys were conducted, one during the weekdays' dan another one during the weekends in which 100 respondents were randomly selected for each survey. This research employed descriptive analysis, t-test for independent samples, and simple linear regression. The results showed that there is no significant difference between the average score of landscape visual quality between weekdays (score 75.44) and weekends (score 78.01). Similarly, there is also no significant difference between the level of visitors’ experience during weekdays (score 78.09) and weekends (80.34). The simple linear regression analysis indicated that the landscape visual quality has a positive influence on the level of visitors’ experience in both categories.

Herpetofauna is poikilotherm and sensitive to temperature change in particular fires, understanding response of these taxa after fire could provide early evidence of ecosystem resilience. It seems very few scientific evidences have been reported for the response of herpetofauna communities after fire. We aim to explore the presence of herpetofauna in the ex-burnt areas of Tesso Nilo National Park in Riau Province and find possible environmental conditions which explain their presence. Field work was conducted during December 2015-February 2016 for collecting presence of diurnal herpetofauna species in burnt and un-burnt areas as well as collecting environmental conditions through transects. Numbers of individual sightings during observation were recorded and measurement of environmental conditions included habitat covers, vegetation density using protocol sampling and nested sampling plots. We also calculated vegetation mortality and composition of dead organic matter for each sites. Fires in 2015 have caused a clear difference on the habitat condition for herpetofauna between burnt and un-burnt, whereas the composition of herpetofauna species was higher in un-burnt areas (10 species) than burnt areas (5 species). Frogs were found in burnt area, confirms their ability to survive in disturbed areas.

The aim of this research is to determine the comparative anatomy of the stem of Gyrinops versteegii (Thymelaeaceae) in Sumbawa Island. Stem samples of G. versteegii were used from collections of the Agarwood Center Laboratory, Faculty of Mathematics and Natural Science, University of Mataram that were taken from Sumbawa Island. This research used permanent slides with freehand section and maceration methods. Observation data consisted of cortex tissues, xylem, pith, and Ca-Oxalate crystals. The results showed that there were four provenances of G. versteegii on Sumbawa Island, namely provenance Pantai, Hajumee, Kayuk Pisak, and new provenance (Tartar provenance). Comparison of anatomy between the stems of G. versteegii provenance Pantai with other provenances had differences in periderm thickness, the pattern of tissue sclerenchyma, interxylary phloem thickness, cortical parenchyma diameter, number of rows of wood parenchyma tissue, tracheid diameter, pith cell diameter, Ca-oxalate shape. Provenance Hajumee with Tartar and Kayuk pisak differed in trachea length, trachea diameter, and the length of the tracheids, while between the provenances of Tartar and Kayuk pisak differed in the frequency of the trachea, the length of the fiber tracheids, the arrangement of the pith radius, and the location of the pith.

Mangrove planting in Progo River Esturaine in Kulon Progo was hindered by its marginal conditions, where the land was dominated by very dynamic sandy substrat. This condition has caused the growth of various planted mangrove seedlings by Forestry UGM team (2015-2016) was very low. Nevertheless, it was found that Sonneratia can grow well in the location. It was expected that Sonneratia can improve site condition so it became suitable for the growth of other mangrove species. This research aimed to assess soil properties of Progo River estuarine after rehabilitation using Sonneratia. Characterisation of soil physical (texture) and chemical (salinity, pH, and soil organic matter) properties were conducted in the Laboratory of Tree Physiology and Forest Soil, Faculty of Forestry UGM. Soil samples were collected from Sonneratia plant area in various growing conditions. The results showed that growth of Sonneratia affected soil physical properties particularly increasing the proportion of clay and silt, but not soil texture class. In general, more proportion of clay and sand were detected in the bigger Sonneratia plants and in the outer section of root system. The growth of Sonneratia also affected soil chemical properties particularly soil organic matter but not soil pH and salinity.

In the cultivation of teak plus Perhutani (JPP) plantations, there is a thinning cycle of plants at a certain age to produce optimal plant growth for other teak trees. The wood waste from thinning in the form of tree tips and branches/twigs is commonly only used as firewood. One of the efforts to diversify the use of thinned JPP wood is processing it into wood pellets. The raw material used is ten years old thinning teak from Perhutani KPH Pemalang, Central Java. The purpose of this study was to identify the effects of adding tapioca flour on the quality of wood pellets from teak branch waste. In this study, the manufacture of pellets was carried out with treatments without the addition of tapioca and the addition of 2.5%, 5%, 7.5%, and 10% w/w of tapioca adhesive. The results showed that the waste of teak branch can be used as raw material for wood pellets, with the characteristics of the water content 6.51-6.97%, volatile matter 76.01-77.37%, ash content 1.37-1.67%, fixed carbon 14.74-15.49%, density 1.14-1.31 g/cm3 and heat value 4192-4319.67 cal/g. The results showed that all parameters met SNI 8021-2014, except for the ash content in the control and 2.5% tapioca treatment.

This study aimed to analyze several secondary metabolite compounds that are antioxidants in the leaves of gaharu plants based on the position of the leaves on the branches. The experimental design used was a non-factorial randomized block design. The research treatment consisted of three factors, namely (A1) young leaves (position of 1-4 leaves from the shoot), (A2) medium leaves (position of 5-8 leaves from the shoot), and (A3) old leaves (position of 9-12 leaves from the shoots). The results showed that the position of the leaves on the branch of the gaharu plant significantly affected the number of secondary metabolites produced. Gaharu plant leaves contain secondary metabolites, namely alkaloids 1.65-4.20%, saponins 2.47-4.00%, tannins 0.69-2.70%, total phenol 29.70-54.68 mg/L, and total chlorophyll 9.21-20.03 mg/L. Tannins and total phenols are functional compounds in gaharu leaves which are antioxidants. The antioxidant properties of this leaf are included in the strong category with an IC50 value of 49.30-68.30 mg/L wherein young leaves have higher antioxidant properties than old leaves.

The species' determination to rehabilitate and enhance the villagers' prosperity needs information on land characteristics, plants' growth requirements, and financial prospects. This study aimed to model the suitability of forest plants, fruit plants, and agriculture crops that are in-situ, desired by the community, and has prospecting financial return based on the biogeophysical characteristics of the Agroforestry Block of the Gadjah Mada University’s Teaching Forest (KHDTK UGM). The land suitability resulted from matching land mapping unit (LMU) characteristics and the plant's growth requirements. The overlay of slope and soil maps generated LMUs. Soil samples were taken and analyzed to identify the characteristics of each LMU. This research suggested that the highest suitability of planting patterns would result in higher land productivity and community prosperity. The Agroforestry Block with the S2 suitability class covered only 26.64% of the area. The land characteristics that inhibit the suitability were solum depth, slope, texture, pH, N, P2O5, and drainage. This research suggested that agroforestry planting patterns in the S2 suitability class should combine timber species (teak and mahogany), Leguminosae (lamtoro and gamal) to improve land quality and as the source of cattle fodder, fruits (jack fruit and mango), and farm crops such as pineapple,..

This research aimed to analyze the increase in income from intensified agrosilvopastoral in Wiladeg Village, Karangmojo Sub-district, Gunungkidul Regency, Yogyakarta, Indonesia. This research employed Participatory Action Research (PAR) to collect data through four cycles of food crop production trials under forest stands. The on-farm trials used the submersible-well technology and lasted for three years. The Average Equivalent Value (AEV) analysis grouped the respondents into two strata based on land ownership. Stratum-1 consisted of respondents with an agrosilvopastoral area of ≤ 4000 m2, while stratum-2 of > 4000 m2. The off-farm intensification trials involved three cow fattening cycles and used Net Present Value (NPV) analysis. The results showed that on-farm trials contributed an increase in AEV, namely 692% on land strata-1 and 462% on land strata-2. The off-farm trials provided an NPV of IDR 14,679,000,00/year in the off-farm sector of cow fattening. Based on these results, intensified agrosilvopastoral was feasible to increase land productivity both on-farm and off-farm in Wiladeg Village.
