Abstract

Sengon (Paraserinthes falcataria (L) Nielsen) is a fast-growing plant that is widely cultivated by people in dry land. Currently, the cultivation of this plant is also mostly carried out on unflooded peat swamp land in Central Kalimantan. Utilization of peat swamp land has good prospects because this land is rich in organic matter as a source of plant nutrition. This study aims to determine the growth of sengon plants and create a plant growth model to predict the diameter and height of plants at a certain age. The research was conducted in Pulang Pisau Regency, Central Kalimantan Province. The model used to predict the growth of sengon plants is a polynomial equation. The results showed that the growth of sengon plants planted in unflooded peat swamp land at the ages of 6, 13, 30, 36, 48, and 56 months namely 3.76 cm; 7.07 cm; 12.94 cm; 13.91 cm; 18.76 cm; and 22.88 cm respectively for diameter (dbh); 4.64 m; 9.70 m; 11.45 m; 12.16 m; 14.75 m; and 15.20 m respectively for shoot height; and 2.37 m; 4.13 m; 4.85 m; 5.28 m; 5.62 m; and 6.21 m respectively for branch-free height. Sengon plant growth model with polynomial equations is y = -0.01802 + 0.739x - 0.0157x2 + 0.0002X3; y= 0.6002 + 0.893x - 0.0236x2 + 0.0002x3; and y = 0.5676 + 0.3777x - 0.0106x2 + 0.0001x3 for diameter (dbh), shoot height and branch-free height, respectively. The equation is valid and has high accuracy so that it can be used to predict diameter, shoot height and branch-free height of sengon plants until the age of 56 months.

Abstract

The capital city of Central Kalimantan, namely Palangka Raya City, almost every year there are always forest and land fires that harm many people both economically, socially and environmentally which will certainly hinder the development of this city, Palangka Raya has a fire-prone area of 33,824 ha. Monitoring forest and land fires with manual field visits which can be very time consuming. To shorten the time and expand the ability to monitor forest and land fires, the use of Unmanned Aerial Vehicles (UAV) or drone images is one solution to map fire-prone areas in all fields. The aerial photography produced by the UAV is processed using the photogrammetric method to produce a responsible aerial photo map covering an area of 41.92 with 17 benchmark points to block fires in the UPR campus forest from spreading.

Abstract

This study aimed to investigate the physical and chemical characteristics of the soil based on the type of land management in the production forest in Banyu Urip Village, Central Lombok. Determination of the sampling point is done by employing stratified random sampling. The sampling points were 22, divided into two types of land: forest land (dominated by MPTS plants and woody plants) and agricultural land (dominated by seasonal plants). Soil samples were taken with two depths, namely 0-10 cm and 10-20 cm. Soil samples taken were disturbed and undisturbed soil with variables of physical properties (texture, bulk density, porosity, and color) and soil chemistry (C-organic). The research results on the physical properties of the soil showed that the soil texture in both types of land was dominated by dusty clay. The average porosity value in agricultural land is 49.33%, and forest land is 49.48% (unfavorable category). The average bulk density value in forest land is 1.39 g/cm3 and in agricultural land is 1.35 g/cm^3 (high category). The soil color of the two land types is dominated by dark brown. The average value of C-organic soil is 1.80% in forest land and 1.72% in agricultural land (low category).
