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.

Conventional skidding techniques applied in natural forests often bring low productivity, high skidding cost, residual stands damage, and soil damage. RIL’s (Reduced Impact Logging) skidding techniques with better performance and more environmentally friendly should be introduced. This study aims to determine the effect of RIL’s skidding techniques on skidding productivity, skidding production-cost, and environmental damages that comprised residual stands and soil inside natural forests. This research was conducted in November-December 2015 at the site of natural production forest administered by PT. Inhutani II (Indonesia’s State Forest Company), in North Kalimantan. The acquired field data, which consisted of productivity, skidding cost, and damages of residual stands and of soil, were each processed into tabulation forms and then calculated for their averages. The results showed that applying RIL techniques could obtain: 1) The average skidding productivity reached 15.070 m3/hour; 2) The average skidding-production cost was IDR 48,883.45/m3; 3) The skidded-timber volume and skidding duration correlated with the average of skidding productivity, with coefficient of determination of 96.4%; 4) The average damage on residual stand due to skidding was 17.10% including canopy damage (12.5%), broken stems (37.5%), stem injury (12.5%), and leaning trees (37.5%), 5). Average soil depth and soil volume due to the topsoil displacement were 0.047 m and 3.726 m3/m; and 6) the use of matting strips can reduce the occurrence of soil damage during skidding.

The Indonesian government strives to increase non-tax state revenues (PNBP). One of the potentials PNBP is using the state assets, such as research stations,for the public interest. This paper was aimed to formulate a strategy for the PNBP potential development using the Logical Framework Approach (LFA), with a case study at the Nagrak Research Station, Bogor. In order to avoid the failure when the PNBP potential development’s stages are implemented, policy makers need to build a hierarchy based on logical thinking of input, activity, output, impact, objectives and summarized them in a work plans matrix. The process of LFA development starts with the analysis of problems, goals,and strategies. Data and information were obtained through participant observation and documentation studies. The results showed that the commercialization of the operational units of research quality’ s seeds and seedlings at the Nagrak Research Station must be supported by the government policy, including: (1) planning of seed and seedling production with the consideration of price competitiveness (2) seeds and seedling production with the financial management flexibilities, and (3) seeds and seedling distribution with stakeholders protection from the non-quality seeds and seedling’s utilization.

Land degradation in the Brantas River Basin occurs very massively as reflected by high erosion and sedimentation. Information related to soil erosion is important since it is one of the basic information in determining the degraded land in a watershed. The purpose of this study was to analyze and identify the distribution of degraded land in the Brantas river basin as an effort to mitigate land degradation through forests and land rehabilitation in suitable locations. Erosion analysis was carried out spatially on a watershed scale using the USLE (Universal Soil Lost Equation) method. Analyses showed that weighted soil erosion values in the Brantas river basin were448.73 tons/ha/year which was classified as high erosion level. The area of 408,818 ha (41.74%) of Brantas river basinneeds erosion handling because 22.51% was identified in the high erosion value category and 19.23% was included in very high erosion values. Those areas were identified as protected forests, production forests, dry land, and mixed gardens. The type of soil and the erodible of soilare part of the determinants of the high value of erosion, but these factors are difficult to manage while land cover types and land management which are the causes of erosion are relatively manageable. The approach to rehabilitate forests and land can be used as an effort to prevent and reduce erosion by taking into account the selection of related types of habitus (form and stratification) and economic value.

The drought that occurs in the dry season is one of the hydrometeorological disasters. A total of 82 villages of 12 districts in Grobogan, Central Java, experience a clean water crisis due to drought because the well, as their main source of water, is likely to go dry. Therefore, a solution is needed to anticipate the water shortage. The aims of this paper is to analyze financially the water harvesting building which can be used as a reference for the community. The research was conducted in Pamor Hamlet, Banjardowo Village, Kradenan District, Grobogan Regency. The method used was to build the rainwater harvesting engineering models, namely (a) recycling tools for washing and bathing, (b) dirt filter wells, (c) three meters depth infiltration wells (1 well and 2 wells), and (d) five meters deep infiltration wells (1 well and 2 wells). Data collection was done by conducting a survey of the community. The data collected were the costs required for the construction of the rainwater harvesting equipment, maintenance, electricity, supporting materials, etc. The income was approached with replacement costs if the community buys water during the dry season. The financial analyses of NPV, IRR, BCR, and PP were employed. The results showed several feasible models to be applied, namely recycling equipment for washing and bathing, dirt filtering equipment, three meters deep infiltration wells (1 piece) and a depth of 5 meters (1 piece). This model is very good to be adopted by the community because it is easy and has minimal costs.
