Jamblang (Syzygium cumini (L.) Skeels) researches are still focused to identify the plant benefits, but that leads to efforts to obtain good seed quality hasn’t been done. This study aims to determine the moisture content testing method, the critical moisture content, and germination testing method (sowing media and first and final count of seed germination). Improving procedure for moisture content testing and identified the best media for germination testing was arranged in a Completely Random Design. Determining jamblang seeds critical moisture content was arranged in a Randomized Complete Block Design. The experiments were repeated four times. Moisture content with slicing method obtained 49.57%. Jamblang seeds critical water content is 41.61% with 50% germination. The best method of germination was sand medium with fresh seeds (90%). The first count of jamblang seed germination occurs on 32 days after sowing and final count on 83 days after sowing.

By 2016, there were 32.70 million ha of degraded forests in Indonesia. If it isnot quickly rehabilitated, there will be land use changes and expansion of industrial forest plantation, which significantlyaffects itsbiodiversity and environmental. This research aims to study the impacts of the gap planting technique with red jabon on soil density and erosion. The research used: (1) the gap planting technique of red jabonwitha proportion of the total gap area to thetotal natural forest area of 40%: 60%, planting distance of 4m x 5m, and the number of trees planted of 200 stems/ha, (2) Digital-Humboldt Static Cone Penetrometer to measure soil density, and (3) stick for soil erosionmeasurement. The results showed that gap planting with red jabon to rehabilitate degraded natural forests increasedthe soil density, but itsvalue was categorized as a very loose soil class. On the other hand, the soil erosionin gap area was lower than in degraded natural forest area, because the condition of a part of the degraded forest was unvegetatedland, and there were the wastes of branches, twigs, and leaves as well as grown grasses on the soil surface that hinder the soil erosion in the gap area. This research concluded, that the impact of the gap planting on soil density can be neglected, and the impact of the gap planting on soil erosion is positive. Further research on social-economic, biodiversity, effective and efficiency aspects of the gap planting technique for forest rehabilitation are needed before its implementation

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 obtusifoliumBurck), 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.

The two fragmented mangrove forests, located in Graha Indah (HMGI) and Margomulyo (HMM) Balikpapan (East Kalimantan), are important habitats for Bekantan, an endemic and endangered animal species in Indonesian Borneo. The local government has put some conservation efforts by promoting those locations as the tourist destinations but they are not optimally well managed. This research aims to determine the visitors’ profiles, perceptions, and potential ticket funding by using questionnaires. Visitors’ ticket funding preferencewas obtained using the Willingness to Pay (WTP) method and analyzed using multiple regression analysis. Visitors’ profiles and perceptions were analyzed descriptively. The results showed that the visitors’ WTP in HMM and HMGI were Rp9.258 and Rp13.980, respectively, strongly influenced by income, type of jobs, and visiting frequency in HMGI. Meanwhile, HMM visitors were dominated by students (63%), with 11-20 years old by age (58%). On the other hand, the visitors’ occupation in HMGI was more varied i.e. private sectors (27%), students (27%) and civil servants (24%), with 21-30 years old by age (35%). Most of the visitors were from the city of Balikpapan that reached, 76% and 62% in HMM and HMGI, respectively. Potential funding from visitors cannot be estimated due to the lack of accurate data on the annual number of visitors. Internet and social media are potential methods to promote ecotourism in both places as well as promoting mangrove and bekantan conservation.

Air pollution is still a serious problem, especially in big cities in Indonesia. One of the heavy metals that is the source of air pollutant and is very harmful to health and the environment is lead (Pb). Mitigation form that can be done for handling lead air pollution is through tree planting. Therefore, it is important to study the appropriate plant species to be recommended for absorbing lead in the air. This study aims to determine the concentration of lead on the leaves of trees around the Kadu Manis Industrial Region, Tangerang. Measurements of lead concentration were carried out using the 3030-H-APHA (American Public Health Association) modification method in 2012 and Working Instructions (IK) metal 01 of 2014. Based on the analysis, there are 5 (five) species which are recommended to be used as the lead absorber: Pinus (Pinus merkusii), Beringin (Ficus benjamina), Kemuning (Murraya paniculata), Flamboyan (Delonix regia), and Bintaro (Cerbera manghas). The lead concentration found on the leaves of these tree species was 770.8 ppm, 440.6 ppm, 229.0 ppm, 168.1 ppm, and 152.1 ppm for pine, beringin, kemuning, flamboyan, and bintaro, respectively. Planting tree species that has the ability to adsorb high lead is one form of mitigation of heavy metal pollution of lead in the air, especially in the industrial region.

The biogeophysical characteristics of watersheds have an important role as a determinant of the river discharge amount in the watershed. Various watershed problems such as flood and drought related to river discharge require data and information. The importance of this data and information will determine a better watershed management plan. The issue of flooding and drought are the important issues in Ralla subwatershed, Souht Sulawesi Province. This study aims to describe the biogeophysical characteristics and the discharge of Lompo Riaja Atas and Lompo Riaja Bawah Rivers in Ralla subwatershed, Lisu Watershed. This research was conducted in from November 2016 to August 2017. Primary data collection was done through river discharge and precipitation measurements during 34 days of observation. Secondary data obtained from government or related agencies such as geological data obtained from Geological map of the Ujung Pandang sheet 1982, the slope data from Aster DEM, land type from RePPProt 1987, land cover data from google earth image 2015. A quantitative descriptive method was used to analyze the data obtained. The results showed that the Lompo Riaja Atas and Lompo Riaja Bawah rivers have relatively similar discharge fluctuation, although they have a different amount of discharge. River discharge of both rivers is more influenced by rainfall compared to biogeophysical conditions such as geology, topography, soil type, watershed area, watershed shape, river length and order, gradient, flow pattern, flow density,and land cover.

The productivity of cajuput plantation has improved through tree breeding, while manipulation of site and management engineering of timber plantations have been less attention. Management engineering can be obtained by determining the optimum cycle of cajuput leaves harvesting. This study aims to determine the optimum cycling of cajuput leaves harvesting at KPH Yogyakarta by considering the biological cycles of cajuput leaves, chemical physical properties, and the yield of cajuput oil. The tools used in the research were digital scales, distillation devices, and testing tools of physical-chemical properties of cajuput oil. The material for research wasthe cajuput plantsat KPH Yogyakarta. Data of cajuput leave-twig biomass were obtained for 9 months from 9 plots which were well distributed on various ages. Biological cycle analysis uses curent monthly increment (CMI) and mean monthly increment (MMI) intersection approach. Analysis of the physical-chemical properties on cajuput oil refers to SNI 3954:2014 on cajuput oil. The results showed that the biological cycles of cajuput leaves were obtained 5 months after leaves harvesting. The chemical physical properties of cajuput oil that meet the requirements of SNI were achieved after the leaves are 7 months after harvested. The yield of cajuput oil which isabove 0.7% was obtained after the leaves are 8 months after harvested. Thus, the optimum cycle for harvestingof cajuput leaves in KPH Yogyakarta is after 8 months.
