Abstract

Penggunaan teknologi penginderaan jauh di bidang kehutanan merupakan salah satu pilihan yang tepat untuk memperoleh data yang cepat, akurat dan relatif murah untuk mendeteksi perubahan penutupan dan penggunaan lahan. Data series citra satelit dengan resolusi spasial yang tinggi digunakan untuk mendeteksi perubahan penutupan lahan di Kawasan Hutan Lindung Reg 22 Way Waya Kabupaten Lampung Tengah dalam kurun waktu 10 tahun terakhir, yaitu tahun 2000, 2004 dan 2010. Metode yang digunakan dalam penelitian ini yaitu metode klasifikasi terbimbing (supervised classification). Hasil analisis citra dan cek lapang menunjukkan adanya perubahan luasan dari masing-masing jenis penutupan lahan. Hutan sekunder (Hs) mengalami penurunan luas tutupan ± 5,2 % pada tahun 2004 dibandingkan dengan penutupan tahun 2000. Pada tahun 2000 hutan sekunder mempunyai luas 686,79 ha, turun menjadi 413,27 ha pada tahun 2004. Selanjutnya pada pengamatan tahun 2010 terjadi peningkatan kembali yang cukup signifikan dengan luas tutupan lahan sebesar 745,58 ha atau sekitar 14,57% dari luas keseluruhan. Peningkatan tutupan lahan hutan sekunder ini kemungkinan besar disebabkan dari hasil kegiatan reboisasi melalui program Gerakan Rehabilitasi Hutan dan Lahan (GNRHL) dan Hutan Kemasyarakatan (HKm) yang dilakukan pada tahun 2003.Kata kunci: Citra Satelit, Klasifikasi Terbimbing, Penutupan Lahan, Hutan Lindung ABSTRACTThe use of remote sensing technology in forestry sector is considered to be a proper choice for detecting land cover and land use changes fastly, cheaply and realitively cheaper. The series of satellite imageries with high spatial resolution was used to detect the land cover changes in Protected Forest Area of Reg 22 Way Waya of Central Lampung District during the last 10 years, namely 2000, 2004 and 2010. The method was used in this research is a supervised classification method. The image analysis results indicate that there were changes of each land cover type area. The secondary forest (Hs) land cover decreased about 5,2% in the period of 2004 compared to the year in 2000 (from 686.79 hectare to 413, 27 hectare). Meanwhile, the observation in 2010, the secondary forest (Hs) land cover was increased significantly against with an area of 745.58 hectares (approximately 14.57% of the total area). The increase of the secondary forest cover is most likely caused by the reforestation program of the Forest and Land Rehabilitation Activity (GNRHL) and Community Forestry in 2003.Keywords: Satellite Images, Supervised Classifications, Land Cover, Protected Forest

Abstract

Population growth and new activity center development give impact on enhancement of residential demand. That demand always improves without be accompanied land availability and that can impact urban sprawl. The research locations are Natar and Jati Agung Sub-district which are designated as urban housing area, located on the outskirts of Bandar Lampung City. Activities will encourage the growth of demand of the private residential property thus this also encourage the building of residential area. The purpose of the research is to identify residential growth rate in the research locations. The research is conducted by using deductive approach. Data is collected by observation, interview, and literature review. Data is analyzed by using spatial analysis methods, nearest neighbor analysis, qualitative and quantitative descriptive analysis. The result of research explains that the highest residential growth rate in Natar Sub-district is 109.44% in 2017 and in Jati Agung Sub-district is 110.50% in 2019. Cluster residential pattern in Natar Sub-district with distribution index value (T) is 0.760346 tends to grow on the primary arterial road. While the same pattern shown in Jati Agung Sub-district with the distribution index value (T) is 0.817923 and tends to grow among new activities center in the South of Jati Agung Sub-district.

Abstract

Spatial Variability of Soil Nutrients Content Related to Rice Yield (T Syam): Soil nutrients content and its spatial distribution are very important data for site specific fertilizer management to supply sufficient crop nutrition.  The study was carried out  at the farmer paddy field in Rejomulyo Village, Metro Town District of Lampung Province. The aim of this study was to evaluate the relationship between soil nutrients content (N, P, K) and rice yield. Soil samples were collected before fertilizers treatment by the grid sampling method and GPS was used as a tool for precisely determine sample site location.  Rice yield data were collected by small plot method on the each-of soil sample location. Spatial analysis using GS + software and statistical analysis using SPSS software. The result indicated that total nitrogen in the soil had a significantly correlation with the rice yield   (r = 0.95**) and their spatial distribution was relatively similar each others.  Spatial maps of soil nutrients content could be used for the variable rate fertilizers treatment, especially for nitrogen.

Abstract

Surround a big river estuary coastline has a dynamic characteristic and change along a period of time, because of anatural process and/or it is accelerated by human activities. The surround Sekampung river estuary coastline located in Rawa Sragi area is one of the most dynamic coastlines in southern Lampung Province that has changed significantly from 1959 (as a natural process) to year 1987 (as an accelerated process by human activities) since the government of Indonesia has applied swamp drainage system for Rawa Sragi area. It is likely that the coastline has changed significantly in the period of 1987 to 2009 (as an increasing intensity of the human activities in the surrounding Rawa Sragi land). The objective of this research was to analyze the coastline change in the surrounding of Sekampung river estuary in two periods of time: (1) the change of the 1959 – 1987 period coastlines; and (2) the change of the 1987 – 2009 period coastlines. The method of this research was a GIS technique, the implementation was divided into three main steps: (1) the first analysis was conducted in laboratory include raster data source analysis and registration, coastline digitations, and overlaying and analysis of the coastline data; (2) field observation (ground check) was conducted to observe and verify the ground existing coastline; and (3) the last analysis wasconducted after ground check activity to improve and to verify the first coastline analysis results. The result of this research indicated that coastline change in the period of 1959 to 1987 increased the coast land as much as 717.19 hectares, but decreased the coast land as much as 308.51 hectares. Furthermore the coastline change in the period of 1987 to 2009 increased the coast land as much as 162.504 hectares, but decreased the coast land as much as 492.734 hectares. The 1959 – 1987 coastline change was a coast land increasing period, but the 1987 – 2009 coastline change was a coast land decreasing period.Keywords: Abrasion, accretion, coast land, coastline, estuary

Abstract

Vegetation has a strong influence on soil characteristics. Vegetation can contribute organic matter sand nutrients to the soil. This study aimed to assess soil fertility through various approaches physical and chemical soil on various types of cover crop in the  arboretum area at University of Lampung, and determined the type of cover crop that had the best effect on soil fertility. The research was be conducted by a survey method, which made observations on the soil characteristics of six species of cover crops following were rosewood (Dalbergia latifolia), teak (Tectona grandis), albizia (Paraserianthes Albiziaria), acacia (Acasia mangium), fern tree (Filicium desipiens), and mahogany (Swietenia macrophylla King). Soil characteristics observed data were the physical and chemical properties, obtained by field observations, through boring profiles and soil sampling. The results showed that soil fertility on rosewood, albizia, acacia and mahogany on campus area of Lampung University had contents of soil organic C, organic matter, and soil total N higher than teak and Fern tree. Litter from Rosewood, Albizia, and acacia had the best effect on soil fertility, so they could be the best covered vegetation to improve soil characteristics related to optimal and sustainable of land management.Keyword : Acacia, albizia, arboretum, cover crop, fern tree, litter, macronutrient, mahogany, rosewood, teak, and vegetation.
