Abstract

The purpose of this study is to analyze land use changes in the Kelara watershed and to assess the suitability of current land use changes with the spatial planning regulation of Jeneponto within Kelara basin. This study integrates various survey techniques, remote sensing, and geographic information system technology analysis. Geospatial information used in this study consists of Landsat ETM 7+ satellite imagery (2009) and Landsat 8 (2014) as well as a number of spatial data based on vector data which is compiled by the Jeneponto Government. Remote sensing data using two time series (2009 and 2014) are analyzed by means of supervised classification and visual classification.  The analysis indicated that land use type for the paddy fields and forests (including mangroves) converted become a current land use which is inconsistent with the spatial planning regulation of Jeneponto.The use of land for settlement tends to increase through conversion of wetlands (rice fields). These conditions provide an insight that this condition will occur in the future, so that providing the direction of land use change can be better prepared and anticipated earlier.

Abstract

The hydrological process that occurs in a watershed is related to erosion process, sediment transport and downstream deposition. Land use changes and watershed management practices will also affect erosion and sedimentation. The purpose of this study was to determine the magnitude of flowrate, suspended load concentration (suspended load), and floating sediment discharge and correlation of floated sediment discharge and flowrate at the Data’ River. Measuring river characteristics is done by measuring river water flow and river slope. Sediment collection floated with EWI (equal with incerentment) method. Laboratory analysis was carried out by calculating the amount of flow discharge, sediment concentration, and sediment discharge. The results showed the lowest amount of flow discharge occurred on 17/12/2016 with a value of 0.271 m3/s with a floating sediment concentration of 17.167 mg / L, and the sediment discharge floated at 0.402 tons/day. The correlation between flow discharge and floating sediment discharge using a sccatter diagram shows that the determination value R2 is 0.9754 with the equation y = 0.1x + 0.4355.

Abstract

The dry land and paddy fields in Takalar Regency are quite extensive which have the potential to support efforts to maintain food security. Land potential can be estimated based on the land capability class. This study aims to determine the potential of dry land and paddy fields in Takalar Regency by using the land capability evaluation method. This research was conducted in Takalar Regency using a descriptive survey method. The field survey used the free survey method on several land units in paddy fields and dry land. Socio-economic data were collected by conducting interviews with farmers in each unit of land analysis. Mapping of land capability classes using Arc-GIS 10.3 software. The study used a simple, qualitative bounding approach developed by USDA (1975) with the criteria for land capability by Arsyad (2010). This study shows that on dry land there are several land capability classes with their respective sub-classes, namely IIIes, IIItews, IVt, IVw, VIt, and VIIt. In paddy fields, there are land grade classes IIIes, IIIews and IVw. Based on the results of the research, it can be concluded that on dry land there is a land capability class, there is a land capability class III , class IV, class VI, and class VI with the dominant limiting factors, namely slopes, erosion, and waterlogging (drainage and flood threat). Meanwhile, the paddy fields consist of class III, and class IV with the dominant limiting factors, namely erosion, drainage, and soil depth.

Abstract

This research was completed using mixed qualitative and quantitative methods. Field surveys were executed in sugar cane plantation throughout South Sulawesi Indonesia. Land suitability analyses were performed using a parametric approach with Storie’s index equation followed up with  correlation analysis using the Pearson correlation. Results revealed that the period for sugarcane crop growth in the humid tropic relatively dry regions of South Sulawesi Indonesia lasted for the months of November to July.  The land suitability for sugar cane in the research location was moderately suitable (S2c) and marginally suitable (S3c, S3s, S3s,f and S3c,w) with limiting factors such as relative humidity during crop maturation phase, the duration of sunlight, soil depth, soil texture, soil pH and soil drainage. Land suitability index at the research location ranged from 25.2 to 55.0; sugar cane yields ranged from 30.3 to 62.0 Mg ha-1 year-1. Pearson correlation coefficient (r) between LSI with cane and sugar productivity were 0.81 and 0.84 respectively, signifying the strength of the correlation between the two values. This also indicates that land suitability index can be estimating the potential crop yield in the humid tropicsthat relatively dry climate regions.

Abstract

Politeknik Pembangunan Pertanian (Polbantan) Gowa memiliki potensi untuk dijadikan sebagai lokasi ekowisata pendidikan, karena ditunjang oleh luas lahan yang dimiliki sekitar 58 ha dan aksesibilitas sangat baik, karena berada pada jalur utama Kota Makassar menuju Kota Malino yang merupakan salah satu destinasi wisata utama di Provinsi Sulawesi Selatan. Penelitian bertujuan untuk melakukan: 1) survei karakteristik lahan untuk kesesuaian pengembangan berbagai jenis ekowisata, 2) kajian evaluasi lahan untuk menguji tingkat kesesuaian lahan berbagai jenis ekowisata. Survei karakteristik lahan dilakukan secara detail dengan menggunakan sistim grid untuk memperoleh data biofisik lahan, sedangkan metode evaluasi lahan yang digunakan adalah metode evaluasi lahan untuk pariwisata. Hasil penelitian menunjukkan bahwa pada Unit Lahan 1 dan 2, sesuai untuk berbagai jenis penggunaan sarana ekowisata seperti tempat bermain, tempat berkemah, taman rekreasi, dan lokasi lintas alam, sedangkan pada Unit Lahan 3 tidak sesuai untuk penggunaan berbagai jenis sarana ekowisata, karena adanya faktor pembatas berupa potensi bahaya banjir dan drainase tanah yang sangat buruk, serta kedalaman air tanah yang dangkal.

Abstract

Lahan pertanian, terutama di daerah tropis seperti Indonesia, umumnya telah mengalami proses degradasi secara intensif, yang dipicu oleh tingginya intensitas curah hujan dan praktek pemanfaatan lahan yang kurang  mengindahkan prinsip konservasi tanah dan air. Akibatnya, telah terjadi kerusakan lingkungan dan penurunan tingkat kesuburan tanah-tanah  pertanian dari tahun ketahun, dengan konsekuensi berupa makin rendahnya produktifitas lahan-lahan pertanian tersebut. Penelitian yang dilaksanakan di  Kecamatan Parangloe, Kabupaten Gowa, Provinsi Sulawesi Selatan ini, bertujuan untuk mengevaluasi  status kerusakan tanah pada lahan budidaya pertanian (lahan kering/cabe, lahan kering/jagung, lahan kering/rambutan dan sawah),  dan dibandingkan dengan status kerusakan tanah pada areal non-budidaya (hutan sekunder, semak belukar). Metode penilaian status kerusakan tanah yang digunakan adalah sesuai PERMEN LH No. 07 Tahun 2006 tentang Tata Cara Pengukuran Kriteria Baku Kerusakan Tanah Untuk Produksi Biomassa.  Hasil studi mengindikasikan bahwa, dengan menggunakan kriteria  Status Kerusakan Tanah pada PERMEN LH No. 07 Tahun 2006 maka, tidak ditemukan adanya perbedaan status kerusakan tanah antara areal bididaya dan areal non-budidaya. Dengan kata lain, parameter yang digunakan untuk menilai Status Kerusakan Tanah pada PERMEN LH No. 07 Tahun 2006 ini, kurang sensitif dipakai untuk menilai perbedaan status kerusakan tanah pada areal budidaya dan areal non-budidaya.

Abstract

Sugarcane (Saccharum Officinarum L) is one of the potential plants and has sufficient economic values with an important role as a source of economic growth in Indonesia. Sugarcane land suitability index in Arasoe, Bone. Sugarcane plantations using a parametric approach and analyzing the relationship between land characteristics and sugarcane production at the study location. This research was performed in 9 (nine) unit lands produced from overlapping slope maps, soil type maps, and PT Arasoe sugarcane map with sugarcane production high (> 50 tons/ha), moderate (40-30 tons/ha), and low (<30 tons/ha). This research took place between July - November 2019. To calculate the land suitability index (IKL) used the parametric method with the Khiddir equation (1986), to evaluate the relationship between IKL and sugarcane productivity using Pearson correlation analysis. Research shows that the value of IKL ranges from 31.56 to 42.43 and classified according to marginal (S3) with limited factors are climate and base saturation. The relationship between IKL and sugarcane productivity was statistically significant as evidenced by the Pearson correlation coefficient r> 0.4 (p <0.05) which showed that along with the increase in IKL, sugarcane productivity also increased significantly.
