APLIKASI TEKNOLOGI UNMANNED AERIAL VEHICLE (UAV) UNTUK MENGIDENTIFIKASI TUTUPAN HUTAN DAN LAHAN DI UNIVERSITAS LANCANG KUNING

Lancang Kuning University Campus (UNILAK) is one of the campuses that has a fairly wide area and has enormous potential, especially related to the use of space whose potential has not been maximally utilized to support the Tridharma activities of higher education. The lack of land use is due to a more detailed inventory of land cover types that have not yet been carried out so that data and information related to existing land cover types are still very minimal. So it is necessary to identify the type of land cover and land cover characteristics at the Unilak Campus, to obtain information and data for further use. Land cover is the mention of biophysical appearance on the surface of the earth consisting of areas of vegetation, open land, built up land, water bodies and wetlands. One of the activities carried out for land cover data collection is land cover inventory activity using applications in the senses and GIS to collect data on land cover types in the study area coverage. Information on the types of land cover can be obtained from land cover data inventory activities through ground check activities or data collection on land cover conditions in the field.

ANALISIS WAKTU KERJA PENGUKURAN TINGGI POHON MENGGUNAKAN KLINOMETER DAN HAGAMETER

Tree height measurement is one part of the inventory activity of standing trees before logging which requires a relatively long time and quite expensive costs, so it needs to use a more productive measuring instrument. There are several commonly used tree height measuring instruments, including the clinometer and hagameter. This study aim is to determine the working time of measuring tree height with clinometer and hagameter. The research method used was to determine the sample tree randomly, then measured the height of each tree with the clinometer and hagameter. In addition, it also calculates the length of time the measurement of the height of each instrument by recording the start and finish time of each measurement activity carried out. The results showed that measuring the height of a tree using clinometer takes 0.68 minutes per tree in average, and using a stick meter aid takes 1.18 minutes in average, and by using haga with a scale board aids takes 0.88 minutes per tree in average. Thus the measurement of tree height by using a clinometer is faster than using haga, while measuring the height of a tree using a hagameter with a scale board is faster than a meter.

Management and exploitation of forest products required for planning to be prepared for sustainable forest exploitation and also taking into account aspects of Sustainability. The so-called aspects are production capabilities, ecological functions and social functions. In order to achieve these matters, appropriate data are needed to present information on the potential for existing forest stands through forest inventory activities. In the inventory activity found some problems that occur in terms of cost, time, problems and human resources needed. Factors that will affect the data we get. These inhibiting factors can be overcome by creating three groups using methods that have been developed both in data retrieval techniques and data processing.The sampling method as a suitable and effective method in which the sampling method used in the inventory activity is a conventional method using a plot or a circle plot with the area and sampling determined according to the age class of the stand. In addition, using conventional methods is another method that also has accurate and precise information. Method of sampling trees. This study aims to the effectiveness and effectiveness of tree sampling methods and circular plot methods, making it easier to find an efficient and effective location in the work area of ​​PT. Perawang Sukses Perkasa Petapahan District. The research was conducted in the plantation of industrial plant Ekaliptus (Eucalyptus pellita) located at PT. Perawang Sukses Perkasa Industri Petapahan District, Kampar District, Riau Province. This research was conducted for 2 months ie in May - June 2018. Based on the results of research conducted method of circular plot will be more effective and has a higher level of accuracy than other methods with a value of 2.9% sampling error. When viewed from a relative point of view, the relative average yield using the tree sampling method of 8 trees is more easily done in a circular manner with a relative value of 200.28% and accuracy is still accountable.

PENGARUH POHON INDUK CENDANA (Santalum album L) DAN PEMANGKASAN CABANG TERHADAP PERTUMBUHAN TANAMAN DI KEBUN BENIH CENDANA – KIAN RAI IKUN, KABUPATEN BELU, NUSA TENGGARA TIMUR

Sandalwood (Santalum album L) is one of the tropic plants that have high economicvalue. Sandalwood exploitation in East Nusa Tenggara province has very longhistory perhaps more than 1000 years therefore unforgetable. Now a dayssandalwood was categorized as rare plant. One of the several ways to conquerthe rare of sandalwood is to build the garden of sandalwood seeds in Kian RaiIkun, Belu Regency. Some steps of these activities are, to inventory the motherseeds trees in Belu and Timur Tengah Utara Regency, seeds collecting, seedgermination and furthermore sandalwood seedlings are planted in the garden ofsandalwood seeds in Kian Rai Ikun, Belu regency. This garden is located about450 m above sea level (asl).On inventory activity were found 5 mother seeds trees located in Biau (Bi) about500 m asl, Alas (Al) 500 m asl, Haitimuk (Ha) 100 m asl, Oesena (Oe) 500 masl and Tialai (Ti) 450 m asl. Planting of sandalwood seedling in this garden arecoordinated to available planting plot. Every planting plot was grown about 200– 250 sandalwood seedlings from the same mother seeds tree. Some activitiesto maintain sandalwood seedling in the garden after planting time are, watering,weeding and pruning the branch. The aim of branch pruning on sandalwoodtrees is to protect the plant from wind disturbance in order not fall down. In ourexperience sandalwood seedling fall down easily if seedling has dense of branchesand leaves.This research was purposed to study the effect of mother seeds trees and branchpruning on sandalwood growth in the field. The result shown that branch pruningdid not give significantly different on sandalwood growth but the mother seedstrees gave significantly different on sandalwood growth in the field during 1 –10 months after pruning. The sandalwood plants from Haitimuk mother seedstree possess the highest in height and branch growth than other plants, while thesandalwood plants from Oesena mother seeds tree possess the lowest in heightand branch growth. The growth of sandalwood in field followed the models oflogistic growth with high determination coefficient about more than 0. 85.

Échanges en surface dans le modèle de chimie transport multi-échelles MOCAGE

Les échanges en surface dans le Modèle de Chimie Transport (MCT) multi-échelles MOCAGE de Météo-France comprennent à la fois les flux d'émissions et de dépôt sec d'espèces gazeuses. Une interface 2D a été développée entre MOCAGE et le modèle de prévisions météorologiques opérationnel français ARPEGE dans le but de calculer des flux à la surface réalistes Pour les émissions, un inventaire global est employé pour le moment; cet inventaire a été construit essentiellement à partir des inventaires des programmes IGAC/GEIA (International Global Atmospheric Chemistry / Global Emission Inventory Activity) et EDGAR (Emission Database for Global Atmospheric Research qui ont des résolutions temporelles annuelles, sai-sonnières ou mensuelles et une résolution spatiale de un degré. Le dépôt sec d'espèces gazeuses, y compris l'ozone, le dioxyde de soufre, les composés azotés, les composés organiques à longue et à courte durée de vie, a été paramétrisé selon [Wesely, 1989]. Le modèle calcule la vitesse de dépôt à partir de valeurs de trois résistances en série, les résistances aérodynamique, laminaire et de la surface. Ces résistances sont calculées en utilisant les champs de surface d'ARPEGE. Les champs liés à la végétation, tels l'indice foliaire, sont prescrits avec une résolution de un degré sur le globe et de cinq minutes sur l'Europe. Un certain nombre de modifications a été apporté à la paramétrisation de [Wesely, 1989], par exemple pour la formulation de la résistance stomatale et celle de la résistance de surface sur les surfaces mouillées. Les valeurs calculées de vitesse de dépôt ont été comparées à des observations et leurs distributions spatiales et temporelles ont été analysées sur deux saisons opposées (hiver et été, sur les différents domaines de MOCAGE, de résolution allant de 2 degrés pour le globe à 0.25 degrés pour la France.
