The purpose of this study was to determine the effect of biochar application in growing media on the development ofthe roots of Falcataria moluccanna seedlings. Biochar from the waste of meranti wood (Shorea sp.) was produced bya slow pyrolysis process using a traditional kiln at a temperature of 600°C. The study was arranged in a completelyrandomized design with three treatments and 15 replications. The treatments were 100% topsoil (control), 5% biocharand 10% biochar addition to the planting media. F. moluccana was grown from seeds germinated in sand media. Afterone month, F. moluccana was transferred to polybags filled with planting media according to the treatment. Theobservations were conducted for four months. The parameters observed were root length, root volume, and root biomass. The results showed that the addition of biochar indicated a very significant difference in root length, root volume, and root biomass compared to the control. However, the two dosages showed no significantly different effect on root growth. This study concluded that the addition of 5% biochar meranti in the planting media could increase theroot growth of F. moluccana. Keywords: Biochar, Falcataria moluccanna, root growth.

The conversion of biomass to energy is known as biomass regeneration. This energy is used to generate electricity and heat. Combustion systems and classification systems are a major category of biomass conversion technology for power and heat production. The temperature in the biomass gasifier plays an important role in producing gas with high calorific value. Temperature can be measured correctly without error and can then be monitored and controlled by the Internet of Things. In this work, various experimental studies were carried out on variations in temperature with changes in the airflow rate. To measure the temperature profile inside the gasifier, DHT22 and NTC (Negative Temperature Coefficient) thermocouple with the selected data acquisition device. From the results of data acquisition using IoT, precision data, and real-time temperature of biomass gasification were obtained using the Wemos D1 device.

Mangrove is known to be a greenbelt of the coast with its function not only for the physical and chemical processes along the coast line affected by sea-and fresh- water current but also functioning as habitat for many animals, including migratory birds. Mangrove in Margasari village or Lampung Mangrove Center (LMC) is dominated by Avicennia marina with density of 333 trees/ha, followed by Rhizophora mucronata with density of 467 trees/ha. Coastline of Lampung Province attracts for birds to migrate from asia to australia and vice versa. About 38 species of birds was found during field observation made on February – June 2018. Some of the birds found was considered to be endangered like a Great Knot (Calidris tenuirostris), some was threatened like Eurasian Curlew (Numenius arquata) and Chinnesse Egret (Egretta eulophotes). Not only birds, mangrove also provides some habitat for many different communities, such fishes, moluscs, crabs, and else in which they can be part of the ecotourism. Generating activities related to mangrove ecotourism provides economic for the locals such as, canoeing, fishing, seedling and culinary. Renting canoes by fishermen might help to generate some income (one canoe is rented for 200.000 rupiah/day). Fishing, for special tourism, in the mangrove which predominantly habitat for mud catfish is promising to generate some local income. Seedling of red mangrove (Rhizophora sp), can be introduced as part of eco- edutourism. Culinary is the most promising acts also to generate local economics, seafood and some other mangrove products can support the mangrove (LMC) ecotourism.

Straw is agricultural waste that has enormous potential as an alternative energy source because of its abundant availability. However, straw has poor intrinsic properties as a fuel. Alkali metal content (especially K) is very high, causing problems in the combustion process at high temperatures. One effort to overcome this problem is by leaching to improve the quality of straw as fuel. This study aims to improve the energetic quality of rice straw through leaching. The study was conducted by soaking rice straw using tofu wastewater. Straw characteristics will be observed based on the soaking time, which is 0 (without soaking), 3.75, 7.5, 15, 30, 60, 120, and 720 minutes. The parameters measured in the study were the pH of tofu wastewater, ash content, potassium content, and calorific value of straw. The results showed that the leaching of minerals from rice straw by soaking for 720 minutes could improve the energetic properties of rice straw. Soaking rice straw can reduce its potassium content from 32% to 1.96% and increase its calorific value from 13.6 MJ/kg to 15.77 MJ/kg.

In the mangrove ecosystem, there are cellulolytic bacteria that act to decompose cellulose in nature. This study aims to obtain cellulolytic bacteria from mangrove forests in Hanura village. Bacterial isolation was carried out using Sea Water Complete Agar (SWCA) media which added Carboxymethyl Cellulose 0.5% (CMC). Characterization of isolates included colony and cell morphology, pH and NaCl stress test, pathogenicity test, and metal influence test on cellulolytic activity. The results of the study obtained 38 bacterial isolates. 16 isolates among them were cellulolytic bacteria and were able to grow well on pH (7 and 10) and NaCl (0%, 3% and 6%) stress media. IBK3, ID2K1 and IA2K3 isolates are non-pathogenic bacteria with rod-positive Gram-positive properties. IBK3 had the highest cellulolytic index of7.36 and grew well on the addition of Fe, Al, Pb and Cu metals.
