Land-use change in peatland area usually related to large carbon dioxide (CO2) emissions owing chiefly to drainage, which lowers groundwater level (GWL), and potentially affects regional and global carbon balances. The dynamics of carbon dioxide emissions from peat soil consists of root respiration (autotrophic respiration), peat decomposition (heterotrophic respiration and litter decomposition), and emission from dissolved carbon in water. Recently, peat decomposition study, which is free from root respiration still limited, even this process is one main factor of carbon balance on peatland environment. This paper analyzed various data about peat decomposition from direct measurement using subsidence and closed chamber methods in Indonesia, at different land conversions, from primary forests to secondary forests and or agricultural and plantations. Generally, different land conversion produced different peat decomposition. Primary forest produced lower peat decomposition compare than that of secondary forest or plantation fields. Peat decomposition also affected by environmental conditions such as groundwater level, soil temperature, and plant species that grow on the land.

Seagrass ecosystem in Youtefa Bay is very important and useful for the local people’s lives in around the Youtefa Bay. Willingness to Pay (WTP) of the locals toward the seagrass ecosystem is their appreciation for the existing value of seagrass ecosystem. This research explored how much the WTP was given by the local people toward the existences of seagrass ecosystem in Youtefa Bay. The data collection was conducted in March to April 2018 located in three villages around the Youtefa Bay, namely Tobati, Enggros and Nafri Villages as many as 228 respondents. Data analysis of this research was quantitative analysis to find out the mean WTP, aggregate and attribute WTP that influenced WTP value. The result of this research showed that there were 202 respondents were willing to contribute or pay and 26 respondents were not. The obtained WTP value of respondents ranged between IDR 0 to IDR 200,000.00 with mean WTP of respondent was Rp 53,464.91/year meanwhile aggregate WTP was Rp 27,480,964.91/year. Variables which had significant influence toward WTP value were participation at seminaries/trainings regarding coastal ecosystem. Meanwhile gender, age, education level, income, and profession or job variables didn’t make any significant influence toward the given WTP value amount.

An epilithic benthic algae functions as a primary producer living on rock substrates. The Autotrofic Index (AI) was measured to understand the level of water pollutions by quantifying an autotrofy organism. This research determined water quality of Pitap river based on the autotrofic level of an epilithic benthic algae and to understand the correlation between the autotrofic level and physicochemical parameters. The measurement of water quality based on Ash-Free Dry Mass (AFDM), the amount of chlorophyll-a and physicochemical parameters were taken every month with two repetitions on September and October 2014. Five sampling sites were selected using a purposive sampling method based on the variety of environmental conditions around the Pitap river. The results showed that the water quality in the upstream (Ajung and Langkap villages) were classified non-pollution (dominated by autotrof compounds) until less pollution (dominated by autotrof-heterotof compounds). Other locations in downstream (Tebing Tinggi, Sungsum and Juuh villages) were determined pollution of water quality by dominance of autotrof-heterotrof components to dominance by heterotof components. Spearman correlation explained that autotrofic index on September 2014 was closely correlated with water temperature and water velocity with their value are 0,954 and -0,794 at significantly α=0,01. On October 2014 water temperature was closely correlated with its value 0,681 at significantly α=0,05.

One of the impacts of reclamation of swamps is poison substances in the water channels, which can cause to pyrite oxidation, sedimentation and accumulation of toxic substances in secondary channels. The reclamation channel unit in Semangat Karya Village has a water pH of ± 3 and has the iron level of 4.95 mg / l. Based on South Kalimantan Provincial Governor Regulation Year 2007, pH grade and iron concentration are over the quality standard, while the water is consumed by the residents for everyday intentions. One of the technologies that are applied to increase the pH and to minimize the concentration of iron (Fe) is constructed wetland with the horizontal sub-surface flow (CW-HSSF). The objectives of this research were to study the dynamics of pH and Fe in the media acid sulfate soils mixed with organic fertilizer (bokashi) 10% at CW-HSSF system using Purun Tikus (Eleocharis dulcis) and Kalakai (Stenochlaena palustris). The conclusion of this research indicated that pH value and absorption of Fe in CW-HSSF using Purun Tikus (Eleocharis dulcis) was better than Kalakai (Stenochlaena palustris).

Soybean is categorized as a plant which sensitive to water deficit or surplus in its life cycle. If water requirement is not sufficient for the growth and development, the soybean will be subjected to stress. Water stress, such deficiency or excess of water in the plant environment is a condition that disrupts the balance of plant growth. Therefore, it is necessary to observe the interaction between drought stress at various growth stages and soybean varieties, and observe which growth stages that would provide the highest yield of soybean know the differences in drought stress in various stadia of plant growth on the growth and yield of two varieties of soybean crops and which currently can give the highest yield in various stadia grow. This research was carried out by using polybag in the greenhouse of Faculty of Agriculture Universitas Lambung Mangkurat Banjarbaru for 4 months from March to June 2017. The experimental design was Randomized Completely Design with Split Plot Design Factorial. The first factor is soybean varieties (V) as main plot, i.e. Grobogan (v1) and Anjasmoro (v2), and the second factor is the growth stages those subjected to drought stress (C) as subplot, i.e. c1 : vegetative stage 3 (29 DAS and 36 DAS), c2 : flowering stage (35 DAS and 46 DAS), c3 pods appearance/emergence (42 DAS and 53 DAS), and c4 : pods filling stage (68 DAS and 76 DAS). The treatment was repeated 3 times and each experiment unit consists of 5 polybags, thus there were 120 plants in total. The crop growth rate, number of main branch nodes, number of effective root nodules, shoot root ratio, the first flowering time, the harvest time, number of pods per plant, number of seed per plant, 100 seed dry weight, and the number of dry seed per plant. The result showed there was no interaction effect between drought stress in various stages and soybean varieties on all variables. Drought stress at vegetative stage 3 (c1) caused the number of main branch nodes, the number of pods per plant, the number of seed per plant, the 100 seed dry weight and the number of dry seed per plant are lower if they are compared to the plants those subjected to drought stress at pod filling stage (c4). Nevertheless, those variables were not different at drought stress at flowering stage (c2), pods appearance (c3) and pod filling stage (4). Soybean varieties observation showed that the Grobogan were faster in flowering time and higher in crop growth (26.49 DAS and 3.08 g d-1 respectively) compared to the Anjasmoro (34.08 DAS and 2.73 g d-1 respectively).

Agarwood has so high value that can trigger an excessive agarwood encroachment in nature; it threatened the agarwood availability. Agarwood cultivation was the right solution to overcome the Agarwood insufficiency. Currently, bioserum has been found to form Agarwood rapidly. It was found by Kusnadi and introduced to the public by BPDASHLWSS (The watershed management and protection forest inquiry). The formation and effectiveness process of bioserum has not been researched yet scientifically. Therefore, this study aimed to determine the success rate of Agarwood formation and the quality of Agarwood with combined injections treatments on tree branches of Aquilariamalaccensis. This research used a complete randomized design with 3 treatments. Each treatment consisted of several vertical injection hole spaces: 5 cm, 10 cm, and 15 cm. The horizontal space for these three treatments was the same, 5 cm. The result showed that the best vertical range of injection was 10 cm. Therefore, each injection hole would produce separate agarwood chips. A 10-cm vertical range injection also made the rest wood between the injection holes not too wide. This Agarwood was classified into kamedangan class with the average weight of 2 g/chips.
