Abstract

Analysis of Erosion Hazard Levels using Geospatial Information Systems in a watershed needs to be known so that it does not become dangerous, especially in the Maluka watershed. This study aims to determine the level of erosion hazard in the Maluka watershed using the USLE (equationUniversal Soil Loss Equation), calculate the rate of erosion and determine the level of erosion hazard using Geographic Information System (GIS). The calculation of the erosion rate in this study ranged from 36.83 tons/ha/year to 3,339.71 tons/ha/year. The type of soil with the highest erosion rate is alluvial type with Open Land Cover (OLC) on steep slopes of 3,339.71 tons/ha/year. While the type of soil with the lowest erosion rate is the type of red yellow pedsolic with Plantation Land Cover (PLC) on flat slopes of 36.83 tons/ha/year. The Erosion Hazard Level (EHL) of the Maluka watershed in this study was grouped into low, medium to high. The level of Erosion Hazard on the low criteria has an area of 3,370.44 ha, on the medium criteria it has an area of 402.92 ha, and on the high criteria it has an area of 6.00 ha. From the observed land units, it was found that EHL in the Maluka watershed was dominated by low criteria, namely plantation land cover. Meanwhile, with high EHL criteria, the total area is low, namely in open land cover.Analisa Tingkat Bahaya Erosi menggunakan Sistem Informasi Geospasial dalam suatu DAS perlu diketahui agar tidak menjadi membahayakan, khususnya di DAS Maluka. Penelitian ini bertujuan untuk menentukan tingkat bahaya erosi di DAS Maluka menggunakan persamaan USLE (Universal Soil Loss Equation), menghitung besarnya laju erosi  serta menentukan tingkat bahaya erosi menggunakan Sisten Informasi Geografis (SIG). Perhitungan nilai laju erosi pada penelitian ini berkisar antara 36,83 ton/ha/thn sampai dengan 3.339,71 ton/ha/thn. Jenis tanah dengan nilai laju erosi terbesar ialah jenis alluvial dengan penutupan lahan terbuka (LTK) pada kelerengan curam yaitu sebesar 3.339,71 ton/ha/thn. Sedangkan jenis tanah dengan nilai laju erosi terendah ialah jenis tanah pedsolik merah kuning dengan penutupan lahan perkebunan (PKB) pada kelerengan datar yaitu sebesar 36,83 ton/ha/thn. Nilai Tingkat Bahaya Erosi (TBE) dari DAS Maluka pada penelitian ini dikelompokkan menjadi rendah, sedang hingga tinggi. Tingkat Bahaya Erosi pada kriteria rendah mempunyai luasan 3.370,44 ha, pada kriteria sedang mempunyai luasan 402,92 ha, dan pada kriteria tinggi mempunyai luasan 6,00 ha.

Abstract

Forest inventory is an activity to determine forest potential which is adjusted to the objectives to be achieved. Forest inventorying activities in other fields such as electricity are known as plant inventories with economic value. The use of electricity is an important factor in people's lives, both in the household sector, lighting, communication, industry and so on. The Government's program, which targets an additional 56.4 thousand megawatts of electricity in the next 10 years, requires a large number of high-voltage air duct. Purpose of this research is to produce data on the types and potential of economic plants on the Amutai-Tamiang Layang HVAD tower site. The method in this research is a 100% census of 120 tower site points, covering three regencies namely Hulu Sungai Utara Regency, Tabalong Regency, and East Barito Regency. The results of this research were 41 species of plants with the potential for plants which were found to be small and unproductive plants as many as 32 plant species and 1979 stems, while the potential for productive plants was 11 species with the number 1076 stems and potential for large plants totaling 25 species with a total of 416 stems. The research location of 120 points is included in the spatial pattern of other use areas so that PT PLN (Persero) no longer carries out a business license for utilization of wood forest products (IUPHHK) to the Ministry of Forestry and the Environment.Keywords: Plants Inventory; Tower Site; HVAD.

Abstract

There are no data on feeding behavior in birds that focus on food types and perch height from ground level while birds eat food. The research aimed to identify the type of food and analyze the height of the perch. Through transects (footpaths, inspection roads) in cultivation crops, settlements, and galam forests in Liang Anggang Protection Forest Area - Block 1, Banjarbaru, Indonesia (KHLLA-1) at 07.00 - 11.00 and at 15.00 - 17.30 and for three replications, birds at a distance of 50 m were observed. The type of food and the height of the perch when the bird ate the food were recorded. Types of food consisted of fruits / seeds, seeds, nectar, insects, fish, and others. Perch height was K-1 for height 0 - <5 m from ground level; K-2 for 5 - <10 m; and K-3 for ≥10 m. One particular bird species that eats certain types of food at certain perch height was called an event. The event ratio was the ratio of certain food types or certain perch height to all events during three replications. Twenty species (14 families) of birds are found to eat and perch. The most dominant type of food eaten is fruit and the least is seeds. Perch height for eating food in general is 0 - <5 m. The number of events at this height is 4.3 - 7.8 times more than the number of events at the height of 5 - <10 m. There is no occurrence that birds eat food at perch height of ≥10 m.Keywords: Bird, Food, Habitat, Perch, Protected Forest

Abstract

There was no data available on the type of food and the height of the perch for birds to eat that food at the Banua Botanical Garden, Banjarbaru. The research aimed to identify the type of bird food and determine the perch height where birds eat. Data were collected from three types of habitat, namely open land, mixed vegetation, and acacia vegetation. Through the survey and point count with a maximum radius of 50 m at 07.00-10.00 and 16.00‒18.30 for 3 replications, birds were observed and the occurrences ―when a certain bird species ate a certain type of food at a certain perch height above ground level― was calculated. Types of food were grouped into fruit, grains, nectar, insects, fish, and others. The height of the perch was divided into three classes, namely Class A (0 - <5 m from ground level), Class B (5 - <10 m), and Class C (10 - <15 m). There are 315 occurrences carried out by 24 bird species (19 families). The most common occurrence is birds eating fruit and grains. The most common perch height where birds do so is Class A.Tidak tersedia data tentang jenis makanan dan ketinggian tenggeran burung memakan makanan itu di Kebun Raya Banua, Banjarbaru. Penelitian bertujuan untuk mengidentifikasi jenis makanan burung dan menentukan ketinggian tenggeran yang sering digunakan oleh burung ketika memakan jenis makanan itu. Data dikumpulkan dari tiga tipe habitat, yaitu lahan terbuka, vegetasi campuran, dan vegetasi akasia. Melalui metode survei dan lingkaran hitung beradius maksimal 50 m pada jam 07.00‒10.00 dan 16.00‒18.30 selama 3 ulangan, burung diamati dan kejadian bahwa spesies burung tertentu memakan jenis makanan tertentu pada ketinggian tenggeran tertentu dari permukaan tanah― dihitung. Jenis makanan dikelompokkan dalam buah, bulir, nectar, insekta, ikan, dan lainnya. Ketinggian tenggeran dibagi dalam tiga kelas, yaitu Kelas A (0 ‒ <5 m dari permukaan tanah), Kelas B (5 - <10 m), dan Kelas C (10 - <15 m). Tercatat 315 kejadian dilakukan oleh 24 spesies (19 famili) burung. Kejadian yang paling banyak ditemukan adalah burung memakan buah dan bulir. Ketinggian tenggeran yang paling banyak ditemukan saat burung melakukan itu adalah Kelas A.
