Abstract

Penelitian  ini  bertujuan  untuk mengetahui pola distibusi  Ruang  Terbuka Hijau  (RTH) dari tahun 2005, tahun 2010, tahun 2015 dan menyusun model distribusi spasial RTH tahun 2025 di Kota Pekalongan. Distribusi spasial RTH dan perubahan penggunaan lahan diperoleh dari hasil pengolahan data citra Digital Globe tahun 2005 dan tahun 2010 serta citra SPOT 5 (tahun 2015). penyusunan model distribusi spasial RTH pada tahun 2025 mempertimbangkan RTRW Kota  Pekalongan  yang  terdiri  dari  ruas  jalan  (jalan  eksisting  dan  rencana  pengembangan jalan) dan rencana pengembangan kawasan.Penelitian ini menggunakan pemodelan berbasis raster dengan menggunakan pendekatan cellular automata yang memanfaatkan LanduseSim 2.0  sebagai  software  pengolahannya  selain  Arc.GIS  10.5    Berdasarkan  hasil  penelitian, menunjukan  bahwa  penggunaan  lahan  di  Kota  Pekalongan  dalam  kurun  waktu  10  tahun terakhir  sangat  dinamis.  Permukiman  merupakan  kelas  penggunaan  lahan  dengan peningkatan luas terbesar sebesar 313,17 hektar. Sedangkan penurunan luas terbesar terjadi pada  lahan  pertanian  yang  berkurang  sebesar  392,58  hektar.  Luas  RTH  eksisting  sebesar 614,51 hektar atau sekitar 13,17%  dengan trend tren perkembangan yang meningkat dalam kurun  waktu  10  tahun  terakhir  (201,63  hektar). Hasil  model  yang  disusun  dengan  tren perkembangan yang terus meningkat maka RTH di Kota Pekalongan diprediksi memiliki luas 816,14 hectar pada tahun 2025. RTH di Kota Pekalongan sebagian besar didominasi oleh jenis RTH  sepadan  jalan  dan  sepadan  sungai  dengan  pola  memanjang.  Prediksi  yang  telah dilakukan  maka  dapat  digambarkan  akan  terjadi  penambahan  luas  RTH  dengan  pola memanjang  sepanjang  jalan  dan  sungai.  Kedepannya  pemerintah  daerah  perlu  melakukan terobosan-terobosan  dalam  pengembangan  RTH  di  Kota  Pekalongan  dengan  alokasi  dana yang memadahi yang dapat diaplikasikan dalam bentuk hutan kota, taman dan sabuk pantai mangrove

Abstract

Surface erosion is one of the determining variable of critical watershed, this related to river basin managementwhich always prioritized to critical land . Along with land use changes that lower watershed function, theassessment of land use change on surface erosion becomes very important. The research was conducted oncatchment of Mrica reservoir, especially in Serayu, Merawu, Lumajang, and Liangan. The data input of land usechanges are from 2001-2009 that using Landsat TM and ALOS. The soil loss calculating method is MUSLE(Modified Universal Soil Loss Equation). DEM data as a function of slope can be used to analyze at pixel level ofaccuracy,soil data as erodibility function, and discharge as erosivity function. Musle analysis results indicatethat the average surface erosion of Mrica reservoir catchment are 16,775,896 tons per year or 11,183,931 m3 peryear, equivalent to the soil loss thickness as 16:13 mm per year. Result of land use changes effect to surfaceerosion in the research area are moor, plantations, and scrub with R :0.85 positive correlation; 0.84, and 0.86.Forest, correlates negatively to the surface erosion with R coefficient: 0.88. Thus, managing land use with highcorrelation coefficient will greater impact to suppress soil loss/ erosion.

Abstract

This research takes location on upstream of Cokroyasan watershed, especially on Bandung weir catchment on Purworejo and Wonosobo District. Research objective is knowing maximum retention changes which represented by upstream Cokroyasan watershed curve number, related to land cover data series, soil type, rain, and peak flow (Qp). Research data quality controlled with data survey and overland flow data observed. Thus the relationship of particular land cover and watershed responses in generating peak flow can be determined.The land covers determine using multispectral classification of Landsat which detailed with manual interpretation and Google Earth image. Sampling selection defines by stratified random sampling technique of the smallest unit of land form. Effective rain determines by consistency test of rainfall data, frequency analysis, survey data and curve number composites. The effective rainfall generate using SCS model (Soil Conservation Service) which influenced by design rainfall, soil type, texture, and land cover.The results showed that within 15 years, the land cover of Bandung weir catchment change significantly. Especially plantation was reduced by 56% or 40.76 km2 while the settlements increased 412% to 64.20 Km2, and other land cover changes not significant (2% <). The analysis showed the peak flow in the upstream of Cokroyasan watershed changes on different return period. Although the different can only see on a more than two years return period. This means there was an increase of peak flow (discharge), as a result of maximum retention DAS dropped from 16- 18.29 m3/ s.The conclusion of this research indicate that land cover changes that occur within 15 years, influence on Curve Number changes, maximum retention, effective precipitation, and peak flow of upstream Cokroyasan watershed.

Abstract

Sub DAS Bompon merupakan daerah yang memiliki permasalahan bencana tergolong kompleks. Dilihat dari morfologinya yang terdiri dari lereng-lereng menjadikan daerah tersebut rawan longsor dan kekeringan terutama bagi penduduk yang tinggal dibagian igir-igir Sub DAS Bompon. Selain adanya dampak negatif, longsor juga memberikan dampak positif terkait dengan ketersediaan sumber daya air alami yakni mata air. Pada penelitian ini, kajian dilakukan pada setiap morfologi Sub DAS. Dari hasil observasi lapangan menunjukkan bahwa penduduk di bagian lereng atas dan lereng bawah perbukitan sebagian besar lebih memilih memanfaatkan mata air untuk kegiatan domestik. Sedangkan di bagian kaki lereng perbukitan, mata air lebih dimanfaatkan untuk kegiatan pertanian dan sebagian besar penduduk sudah menggunakan sumur dan PAM. Penelitian ini bertujuan untuk mengidentifikasi persebaran mata air dan air tanah serta menganalisis cara-cara pengelolaan penduduk dalam memanfaatkan sumber daya air dari mata air dan sumur. Dalam memanfaatkan dan mempertahankan kualitas mata air, penduduk melakukan strategi seperti membuat kolam tampungan, menancapkan bambu di pinggir tampungan mata air, membangun sumur pribadi maupun komunal, hingga mencari mata air di luar Sub DAS Bompon, dan lain-lain.Sub DAS Bompon is an area that has a complex disaster problem. Judging from the morphology that consists of slopes make the area prone to landslides and drought, especially for residents who live in the apex of Sub Basin Bompon. In addition to the negative impacts, landslides also provide a positive impact associated with the availability of natural water resources,  springs. In this study, the study was conducted on each sub-basin’s morphology. Field observations show that the population on the upper slopes and the slopes below the hills mostly prefer to use the spring for domestic activities. While at the foot of the slopes (toe), springs are more used for agricultural activities and most of the people are already using wells and PAM. This study aims to identify spread of the springs and analyze ways of managing the population in utilizing water resources from the spring. In utilizing and maintaining the quality of springs, residents to do strategies such as creating a pool of shelters, bamboo sticking on the edge of the pool, to find springs outside the Bompon River Basin, and others.

Abstract

The Garang watershed is one of the main rivers passing through Semarang City, Central Java. Garang uptream is mostly a buffer zone and a catchment area for the water and soil resources conservation of Semarang City and surroundings. This research is located in the upstream Garang watershed, with the aim of knowing the level of erosion or soil loss tolerance due to land use change.The erosion model is specific to sheet erosion which modeled with RUSLE (Revised Universal Soil Loss Equation) method. The data used are (R) ground rainfall from 7 hydrological stations for 10 years, (K) soil types derived from land form interpretation, (LS) length and slope from SRTM radar data, (CP) conservation and land cover derived using a multispectral supervised classification (maximum likelihood). The quality of modeling is maintained through validation of input data, such as the normal ratio method and consistency test of rain data, soil texture and color surveys for soil data, confusion matrices for land cover and slope validation.The research results of the upstream Garang watershed area of 1191,56 hectares (14.14%), the erosion that occurred was still below the allowable erosion limit, while the area of 7.232,67 hectares (85.86%) was erosion that occurred above the allowable erosion value. The average soil loss is 222 tonnes / ha / year with the potential for soil loss up to 39,236 tonnes per year or soil loss thickness of 3.8 cm. Even though it is within the threshold, this must be controlled considering the importance of the upstream Garang watershed, whose land cover has begun to change its function to agriculture and plantations on sloping land.
