Abstract

Bencana banjir akibat luapan Sungai Samin menjadi salah satu permasalahan utama di Kabupaten Sukoharjo. Perlu pengendalian bencana yang lebih menekankan pada pengurangan resiko (mitigasi). Masyarakat sebagai pihak pertama yang berhadapan dengan resiko bencana sehingga mitigasi lebih efektif dengan partisipasi aktif masyarakat. Penelitian bertujuan untuk memetakan potensi tingkat kerawanan banjir dan menganalisis upaya mitigasi bencana banjir melalui program pengembangan masyarakat tangguh bencana sebagai bentuk partisipasi masyarakat di Sub DAS Samin. Metode menggunakan teknologi sistem informasi geografis (SIG) dengan pendekatan map-overlay dan scoring beberapa peta parameter banjir (kemiringan lereng, jenis tanah, kerapatan drainase, curah hujan dan penggunaan lahan) dan survey wawancara untuk mengetahui upaya mitigasi yang diterapkan. Hasil menunjukkan bahwa tingkat kerawanan banjir wilayah Sub DAS Samin sebagian besar termasuk tingkat rawan – sangat rawan yaitu seluas 53,826,73Ha (84,77%). Daerah yang termasuk kategori rawan – sangat rawan berada di wilayah hilir dan tengah meliputi Kecamatan Mojolaban, Polokarto, Bendosari, Sukoharjo, Karanganyar, Jumapolo, Jaten, Karanganyar, dan Kebakkramat. Berdasarkan hasil analisis spasial dan wawancara bahwa Desa Tegalmade yang terletak di Kecamatan Mojolaban merupakan daerah dengan tingkat kerawanan bencana banjir tinggi. Hasil peta kerawanan bencana banjir dapat diintegrasikan sebagai sebuah rekomendasi dalam perencanaan tata ruang berbasis mitigasi bencana. Upaya mitigasi bencana banjir yang diterapkan yaitu dengan pengembangan masyarakat tangguh bencana di Desa Tegalmade. Pengembangan masyarakat tangguh bencana dilakukan melalui penyiapan infrastruktur berupa perbaikan tanggul secara permanen, perbaikan lingkungan berupa penanaman tanaman konservasi “Bambu” di sempadan sungai, penyiapan kelembagaan dan kesiapsiagaan baik pemerintah terkait maupun masyarakat rawan bencana, sehingga potensi kerawanan banjir dan dampak yang ditimbulkan bisa diminimalisir.Kata kunci : kerawanan banjir, mitigasi, sig, masyarakat tangguh bencana

Abstract

Sandy soil has limitations factor in supporting plant growth such as low soil organic carbon (SOC), cation exchange capacity (CEC), macro-micro nutrient content, water retention capacity, and high permeability rate. To improve soil conditions, it can be done by adding mycorrhizae and soil amendments. This study aimed to determine the effect of mycorrhizae application and soil amendments on the P availability and P uptake of plants in sandy soil. The research was conducted in a greenhouse of Agricultural Faculty, Sebelas Maret University. Used a completely randomized design consisting of 2 factors. The first factor was mycorrhizae with 2 levels, namely without mycorrhizae (M0) and mycorrhizae with 6 spores/plants (M1). The second factor was soil amendments; without amendment (P0), cow manure 60 tons/ha (P1), rock phosphate 150 kg/ha (P2), and combination of cow manure 60 tons/ha and rock phosphate 150 kg/ha (P3). The results showed that the application of mycorrhizae and soil amendments significantly increased available P, SOC, CEC, P concentration, and P uptake. Interaction of mycorrhizae 6 spores/plant and rock phosphate 150 kg/ha was able to increase the availability of soil P up to 12.8 times, plant tissue P concentration up to 1.4 times, and P uptake up to 2.27 times compared to the control. Application of mycorrhizae 6 spores/plant and cow manure of 60 tons/ha gave the best results on SOC and mycorrhizae with a combination of cow manure and rock phosphate gave the best results on CEC.

Abstract

This research was conducted with the aim of studying land use change and evaluating the impact of land conversion on land capability in Tirtomoyo District of Wonogiri Regency. This research employed a descriptive, explorative method by utilizing SIG Arc Map 10.1 and Google Earth Pro software. The analysis of land use change, especially agricultural land, was conducted through visual interpretation of Google Earth Pro satellite imaging in 2004 and 2016. A ground check was done by land survey. Soil sample analysis was done to determine land capability class. Based on research results, it was found that eight locations experienced land use change. Location 1 had changed from secondary forest to moor, location 2 from moor into farm, location 3 from bushes into paddy field, location 4 from paddy field into farm, location 5 from paddy field into farm, location 6 from moor into paddy field, location 7 bushes into moor, and the location 8 from paddy field into farm. Land use changes showed different results of changes in soil physical properties based on soil characteristics at each type of land use. Changes in land use generally had less impact on land use class change. Locations 1, 6, and 7 did not experience changes in land capability class, but there were changes in the sub-classes of land capability. Locations 2 and 8 did not experience changes in class or sub-classes of land capability but sites 3, 4, and 5 indicated changes in land capability class by inhibiting factors namely permeability class in a paddy field.

Abstract

The demand for shallots is getting higher as the population grows. Indonesia targets to become a self-sufficient country of onion and the largest exporter of shallots in ASEAN by 2045. One of the shallot production centres is Losari District, Brebes, but the shallots productivity has decreased, so it is necessary to know the cause and the improvement effort to overcome it. The research was a land survey and evaluation to determine the current and the potential land suitability classes for the shallot. Data analysis using LMU (Land Map Unit) as the unit of analysis, which is the result of an overlay of soil type map, slope map and land use map using ArcGIS 10.3. The sampling method was purposive sampling and data analyzed using the matching method between the results of land characteristics data with the requirements of shallots growing. Results showed that even in production centres, the current suitability classes are marginally suitable (S3) as the heaviest limiting factors are very high rainfall. Improvement efforts to overcome this can be done by using suitable varieties, making gully drainage and using mulch/shade so that the potential land suitability class increases to be moderately suitable (S2).

Abstract

Determination of soil quality in Giriwoyo Sub-district, Wonogiri Regency, will generate a Soil Quality Index which can be used as a reference for soil cultivation for optimal productivity. This research was a descriptive exploratory with a survey approach. The survey area consisted of 12 land mapping units (LMU) with 3 replications for each LMU. Determination of LMU based on soil type, land use, slope and rainfall. The parameters used were BD (bulk density), porosity, organic C, pH, CEC (cation exchange capacity), BS (base saturation), available P, available K, total N, and MBC (microbial biomass carbon) that represented the physical, chemical and biological properties of the soil. Principal Component Analysis (PCA) analysis was performed to obtain the Minimum Data Set (MDS). The Soil Quality Index (SQI) at each LMU was calculated by multiplying the PCA result score (Wi) with the score for each selected indicator (Si). The result showed that the Soil Quality Index at each LMU was low. The highest Soil Quality Index was found in fields land use with an SQI of 0.34. The soil indicator that limited the soil quality was available P.

Abstract

This study aimed to determine the status of soil damage in Pitu District, Ngawi Regency. The study was conducted in a descriptive exploratory with survey methods. Determination of site sampling was done by purposive sampling, based on distribution or division and land use categories from the results of map overlays. Assessment of soil degradation potency was based on land units from the uniformity of the soil, rainfall, slope, and land use map. Land units resulting from overlay were scored based on the results of multiplication of weights and soil, slope, rainfall, and land use ratings. Total score indicates soil Degradation Potency (SDP). Assessment of soil degradation status was done through matching and scoring. Field observation results were matched with the standard criteria of soil degradation from Indonesian Government Regulation No. 150 of 2000. Each parameter was scored, then the total score was used to determine soil degradation status. Soil degradation potency in Pitu District, Ngawi Regency is PR II (Low) at LMU (Land Map Units) 1, 3, 4, 5, and 8, and PR III (Moderate) at LMU 2, 6, 7, 9, and 10. Soil degradation status in Pitu District, Ngawi Regency is slightly degraded at all LMU, with limiting factors, namely texture, bulk density, total porosity, and permeability.

Abstract

Environmental degradation, which is caused by the quarry, is a complex problem. The site of the quarry within an agricultural land and forest makes land become critical. Rehabilitation of the area can be conducted by reclamation. Revegetation using local species is no better than pioneer species. Based -on Indonesian regulation-in Permenhut P.4/Menhut-II/2011, revegetation using fast-growing species is important for a precondition before enrichment using climax species, so then it needs an evaluation of land suitability for the fast-growing species. The study of revegetation was conducted at quarry clay which the characteristics of this study were description and exploration with field survey supported by laboratory analysis. Data obtained were analyzed by giving weights and scores of species characteristics to decide selected species of vegetation, then the soil characteristics and qualities were matched with species growth requirements. The results showed that jabon (Anthocephallus cadamba) and sengon (Falcataria moluccana) are selected species for revegetation. Land suitability classes of jabon and sengon are not suitable (N) and land suitability of jabon and sengon can be increased to be marginally suitable (S3) by reclamation using potting system that includes building drainage, improvement of depth, soil pH, application of fertilizer, dolomite, and gypsum, application of grass mulch and collecting large rocks for making the terrace.
