Abstract

Pertumbuhan penduduk merupakan salah satu faktor yang dapat mempengaruhi dinamika penggunaan lahan melalui hubungan yang kompleks antara kebutuhan manusia untuk memenuhi kebutuhan sebagai tempat tinggal dan kebutuhan produksi pertanian. Kabupaten Gowa mengalami perubahan lahan sangat signifikan dari tahun ke tahun disebabkan karena pertumbahan penduduk Kota Makassar dan Kabupaten Gowa sendiri. Perubahan penggunaan lahan menyebabkan konversi lahan dan tekanan pada sumber daya lahan. Penelitian ini bertujuan untuk mengetahui dinamika pola perubahan penggunaan lahan produktif terhadap perkembangan kawasan urbanisasi dari Kota Makassar ke arah transek jarak wilayah Kabupaten Gowa. Penelitian ini dilaksanakan di Kota Makassar dan Kabupaten Gowa yang mencakup wilayah Kecamatan Manggala, Pattalasang, Parangloe hingga Tinggimoncong. Perubahan penggunaan lahan dilihat dengan menggunakan metode klasifikasi terbimbing berdasarkan data citra satelit pada tahun 2000, 2010 dan 2020. Hasil penelitian menunjukkan bahwa terjadi perubahan penggunaan lahan secara pesat pada tahun 2000, 2010 dan 2020 di wilayah Kota Makassar dan Kabupaten Gowa. Dinamika pola perubahan penggunaan lahan terhadap perkembangan kawasan urbanisasi Kota Makassar ke arah wilayah Kabupaten Gowa berdasarkan transek jarak pada setiap penggunaan lahan sawah, kebun campur, pemukiman, lahan kering, lahan badan air terus meningkat,sehingga menyebabkan penurunan jumlah hutan yang semakin menurun.

Abstract

Using biological agent microorganisms such as Arbuscular Vesicular Mycorrhiza (AVM) is needed to improve post-mining soil fertility. This research aimed to explore and identify morpho species of AVM in the post-nickel mining areas Soil samples were taken from the tree rhizosphere at each representative point. The soil samples have been isolated using Brundrett's method of wet sieving and decanting; AVM spore density is determined for each 20 g soil sample; and spores are grouped based on morphological traits up to the morphogenic stage of the species. The results showed that there are four mycorrhizal species found in the rhizosphere of plants in the nickel post-mining soil of PT Vale Indonesia Tbk., namely Gigaspora sp, Acaulospora sp, Glomus sp, and Scutellospora sp. Gigaspora sp, Acaulospora sp, Glomus sp, and Scutellospora sp obtained 18, 8, 8, and 7 morpho species, respectively. The highest spore density is 34 spores of Gigaspora sp4 found in the rhizosphere of Casuarina rumphiana, 57 spores of Acaulospora sp1 in the rhizosphere of Macaranga gigantea, two spores of Glomus sp1, sp2, and sp6 each as many as two spores per 20 g of soil in rhizosphere of Enterolobium cyclocarpum, Dillenia serrata, Maesopsis eminii, 11 spores of Scutellospora sp6 in the Shizigium sp rhizosphere. One finding revealed that Gigaspora and Acaulospora predominated in the rhizosphere over other mycorrhizas. The results of this AVM identification will be the basis for the mass propagation of local AVM for broader use in the post-nickel mining land area in Sorowako. Widespread use of AVM is a form of post-nickel mining land management based on local resource potential, particularly the dominant trees rhizosphere and the most commonly found AVM types. This proves that AVM can colonize plant roots in this nickel post-mining soil and potentially be mass-propagated, especially species.

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

The varied topography will influence the soil formation. This study aims to characterize and classify the soil selected on different topography positions of the sugarcane plantation area. The research was conducted in sugarcane plantation area of Camming, District of Bone, South Sulawesi, which was carried out from November 2017 to March 2018. This study used a descriptive method, observation and description of the nine soil profiles at three transects. Each transect consisted of three profiles points located in different positions, consisting of summit, backslope, and valleys. Each horizon soil samples were analyzed for their physical, chemical and micromorphology characteristics in the laboratory. Soil classification system was done by using soil taxonomy to the level of subgroups. The results showed that an average rainfall annual on the research location was 2.200 mm per year. Soil characteristics such as soil solum, cation exchange capacity, and sum of basic cations tended to increase in parts of the valley than in the back and summit. The primary mineral from the sand fraction included quartz, calcite, biotite, opaque, and orthoclase found especially in the position of the back and valley. The pore types consisted of vugh and packing void pores. Pedofeature type of soil was generally in the form of concretions and nodules that showed the process of oxidation and reduction. The soil type in the study area was classified into Typic Haplustepts and Typic Haplustalf.
