Abstract

The use of unmanned aircraft (UAV) or drones, apart from being used for mapping, can be a solution for quickly obtaining information and carrying out forest inventories with very detailed resolution results. Plantation Monitoring Assessment (PMA) aged 6 months is an initial inventory activity, later the data from PMA 6 will be the basic data for subsequent PMA. So, with drones, it is hoped that satisfactory results will be obtained. Apart from that, drones can be used to count the number of live and dead trees as well as empty spots. This research aims to compare the results of tree calculations directly in the field with the results of drone photos. This research was carried out on 6 month old Eucalyptus pellita plants in compartment A034, Baserah Sector, PT. RAPP. Data collection was carried out using systematic random sampling with a sampling intensity of 1%. The data taken is in the form of data on the number of live and dead/empty plants in the field and photographed with a drone. The test was carried out to test the differences in the number of dead/empty plants directly in the field and calculations using drone photos, namely the t test. The results showed that there was no difference between the number of live and dead/empty plants in the field and from drone photos.

Abstract

Another Components simple agroforestry at Widodomartani ngemplak sleman yogyakarta indonesia is Cassava. Cassava for food can increase value economic with feed silkmoth samia ricini. The background that thus will sericulture  Samia ricini. The aims research were to determine time and product sericulture samia ricini. The method research  with sericulture samia ricini. The leaves cassava  for feed samia ricini. The  data collection on the time  for feed, percentage life larvae until coccon,  time results coccon, brieght coccon producted. The material researchers, larva Samia ricini 11 th day from 1 gr egg Samia ricini, the leaves cassava edibled and cassava karet non edible, with before feed leaves ricinus comunis. Samia ricini culture used silkmoth rearing rack. Results of the research showed that ecdysis procces 15 th day, after ecdysis increases actifity feeding very high until 21th day. Start coccon 22th day until 26th day the end larva last feeding leaves. The life percentage 95,87 %, feed cassava edible 94,89 %, an ond feed cassava non edible 96,53 %. The coccon producted start 22th day until 26th day , with weight rate coccon cassava edible 2.10264 gr, cassava non edible 2.109893 gr.

Abstract

Eusideroxylon zwageri wood is a type of wood wich have high natural durability  that contains extractive compounds such as alkaloids, tannins, saponins, flavonoids, and phenolics that are toxic to wood-destroying organisms. The ironwood sawmill industry produces waste in the form of sawdust that has not been used but only disposed of into the environment. Therefore, that wood sawdust waste can be used as a natural wood preservative to preserve  wood whish have low natural durability such as   Anthocephalus cadamba.  In this study, A. cadamba wood preservation was carried out with irondust extract with various solution formulas, namely 5%, 10%. 15% and 20%. The purpose of this study was to know the effect of irondust extract solution formula as a preservative on the results of jabon wood preservation which includes absorption and retention of preservatives, mortality of dry wood termites, and the percentage of weight reduction of test samples after being fed to dry wood termites. The results of this research showed that the irondust extract solution formula had a significant effect on the absorption and retention of preservatives and the mortality of dry wood termites. The 20% irondust extract solution formula  resulted in a higher preservative retention and drywood termite mortality value than the 5%, 10% and 15% solution formula, which was 12.13 Kg/m3 for retention and 88% for drywood termite mortality.

Abstract

Mangrove forest is one of the forests that has the highest carbon storage in the tropics and is very high compared to the average carbon storage in various other forest types in the world, which contains around 1.023 Mg of carbon per hectare. This study aims to obtain a model for estimating the biomass potential of mangrove forests in Rembang Regency by utilizing Sentinel-2A Satellite imagery and making a map of the distribution of mangrove forest biomass potential through the best equation model. Sampling was done by purposive systematic sampling method. The correlation test results obtained a value of 0.640 which states that there is a strong relationship between biomass and NDVI. Biomass estimation modeling uses equation models namely Linear, Quadratic, Power, and Exponential. Model selection is done by considering several parameters such as R², RMSE, Bias, χ²-hit, SA, and SR. The selected model for estimating mangrove forest biomass potential is the quadratic model ???? = 17.4 -110.2 ???????????????? + 220 ????????????????² with an R² value of 0.474, RMSE value of 51.55, Chi-square test result of 3.46 and has the highest score value. The potential biomass distribution map generated from the selected model consists of 3 classes, namely classes < 3.7 (tons/ha), 3.7-10.5 (tons/ha), 10.5-35.7 (tons/ha). Mangrove forests in Rembang Regency have dominant biomass potential in the 10.5-35.7 (tons/ha) class.

Abstract

Aek Natonang Arboretum Ecotourism in Samosir Regency, North Sumatra Province has natural beauty that can be used as a tourist attraction for every visitor. The natural beauty that is owned in reality is not calculated into economic value or market value, so it is important to do economic valuation. By doing this research, it can be known the characteristics of visitors, the amount of economic value of Aek Natonang Arboretum ecotourism based on the travel cost method and find out the factors that influence the intensity of visits. The economic valuation method used is the travel cost method. The travel cost method is applied to estimate the economic value of Aek Natonang Arboretum ecotourism by calculating the cost of travel expenses. Data on travel costs and the number of visits were collected through interviews using questionnaires to visitors within a certain period of time. Then proceed with multiple linear regression analysis to determine the factors that affect the intensity of ecotourism visits to Aek Natonang Arboretum. The results of economic valuation with the travel cost method obtained an average value of Rp238.170,00/visit and the economic value of Aek Natonang Arboretum ecotourism is Rp2.358.359.340,00/year. Factors that influence the intensity of visits are distance, length of travel and travel costs.
