Nowdays, mining and energy are still as important sectors for contributing state economics. However, mining activitis usually make environmental problems because most of mining use open pit mining technique that causing the change for the landscape comprising topography, cover vegetation, hydrology pattern, and distruction of soils. In the consequence, the ecosystem of mining area and its surrounding will disturb. The disturbances will more clear if the overburden containing unstable minerals in oxidize condition (such as pyrite and chalcopyrite) release acid mine drained that disturbing biota growth. Zeolite is aluminosilicate mineral group having unique structure, high cation exchange capacity, porous, and adsorp of ammonium ion and water. With those properties, zeolite can be used as (a) absorp of undesirable elements or compounds such as heavy metals, (b) carrier of nutrients such as ammonium ions, and (c) increasing buffer capasity of soils. This paper will dicuss the prospect of zeolite as material for remediation of abandoned mine land.

The problems of the rice field sustainability in Java as the national rice producer are induced by the rice field land conversion into settlement and industrial areas due to the increase of population. The rice field conversion causes the decrease of both land quantity and quality. As mentioned in Act Number 26/2007 concerning Spatial Use management, the goal of implementing the spatial use management is to achieve the protection of spatial use function and the prevention of the negative impacts of the environment resulted from the spatial use implementation. The objective of this study is to assess the consistency of the governmental policies in implementing the Act Number 26/2007 to achieve the rice field sustainability on the basis of agro-ecological concept. By using the GIS modelbase, the rice field agro-ecological zones proposed as standard rice field areas for the benchmark of the sustainable rice field agriculture management system were synthesized from the spatial database of land system, land cover, area status, agro-climate, irrigation condition, social and culture integrated in the administration boundary layers. The results show that the governmental policies from non-agricultural sector in allocating the area status of the settlement areas as presented at the provincial regional spatial use planning map (RTRW map) have not fully consistent to the regulations as stated in Act Number 26/2007 for protecting the productive rice field function as the national rice producer. The potential loss of the rice production caused by the implementation of the rice field conversion into settlement areas allocated at the productive rice field agro-ecological zones is predicted 3.5 million tons per year.Key words: rice field agro-ecological zone, spatial use management, GIS modelbase, land conversion.ABSTRAKMasalah keberlanjutan lahan sawah di Jawa sebagai lumbung beras nasional dipicu oleh konversi lahan sawah menjadi daerah permukiman dan industri karena peningkatan jumlah penduduk. Konversi lahan sawah mengakibatkan penyusutan dan degradasi lahan sawah. Sebagaimana yang diamanatkan dalam Undang-Undang No.26/2007 tentang Penataan Ruang, tujuan penataan ruang adalah untuk melindungi fungsi penggunaan ruang dan mencegah dampak lingkungan sebagai akibat dari implementasi penggunaan ruang. Tujuan penelitian ini adalah untuk mengkaji konsistensi kebijakan pemerintah sebagai implementasi Undang-Undang No. 26/2007 dalam menjaga keberlanjutan lahan sawah berdasarkan konsep agrokologi. Dengan menggunakan basismodel SIG, zona agroekologi yang diusulkan sebagai acuan untuk penetapan luasan baku lahan sawah disintesa dari basisdata sistem lahan, penutup lahan, status kawasan, agroklimat, kondisi irigasi, dan sosial-budaya yang diintegrasikan dalam layer batas wilayah administrasi. Hasil penelitian menunjukkan bahwa kebijakan pemerintah di sektor non-pertanian dalam pengalokasian status kawasan permukiman ternyata tidak secara penuh konsisten dengan Undang-Undang No.26/2007 dalam menjaga keberlanjutan lahan sawah produkif sebagai lumbung beras nasional. Potensi kerugian proudksi beras dari akibat implementasi kebijakan tersebut diperkirakan mencapai 3,5 juta ton per tahun.Kata Kunci: zona agroekologi lahan sawah, penataan ruang, basismodel SIG, konversi lahan.

ABSTRAKAlih fungsi sawah terus terjadi di Pulau Jawa sehingga mengancam ketahanan pangan nasional. Rencana Tata Ruang Wilayah (RTRW) dan kebijakan Lahan Pertanian Pangan Berkelanjutan (LP2B) belum mampu mengendalikan alih fungsi sawah. Penelitian ini bertujuan untuk membangun model penetapan lahan sawah berkelanjutan menggunakan metode regresi logistik dan evaluasi lahan multikriteria. Penelitian dilaksanakan di Kabupaten Sukabumi yang merupakan wilayah perbukitan di bagian selatan Pulau Jawa dengan luas lahan sawah yang cukup besar dan mendukung ketersediaan pangan nasional. Pemodelan dibangun berdasarkan karakteristik alih fungsi lokal dengan mempertimbangkan konsep pembangunan berkelanjutan. Variabel-variabel penting yang mendukung terjadinya alih fungsi sawah yang dipertimbangkan adalah jarak sawah terhadap jalan, permukiman, dan industri. Hasil regresi logistik selanjutnya menjadi masukan bobot bagi evaluasi lahan multikriteria yang dapat menghasilkan tiga skenario kebijakan perlindungan sawah, yaitu standar, protektif, dan permisif guna kepentingan pembangunan. Melalui pemodelan ini diperoleh sawah-sawah prioritas lindung yang memudahkan pengelolaannya dan sekaligus menjadi penyangga bagi sawah-sawah di belakangnya.Kata Kunci: model perlindungan lahan sawah berkelanjutan, regresi logistik, evaluasi lahan multikriteriaABSTRACTConversion of paddy fields has continuously occurred in Java Islands, thus threatens a national food security. The Regional Spatial Planning and the Policy on Sustainable Food-crop Agricultural programs seem to unable to control paddy field conversion. This research was conducted to develop a sustainable paddy field zone delineation model using logistic regression and multicriteria land evaluation. The research location is in the Sukabumi Regency which is has various morphology and large paddy fields to support national food security. The model is developed by local conversion characteristics and considering the concept of sustainable development. Important variables that contribute to paddy fields conversion are the distance to road, settlements and industrial regions. Results of logistic regression then become the input for weighted criteria to develop three policy scenarios of paddy fields protection; standard, protective, and permissive in order to support regional development. Through this model, we obtain the priority paddy fields to be protected as well as become buffer zones for the surrounding paddy fields.Keywords: paddy fields protection model, logistic regression, multicriteria land evaluation

Abstrak. Kini isu ?skala? menjadi penting kembali dibahas oleh komunitas sumberdaya lahan. Awalnya sumberdaya lahan terbatas dikaji oleh disiplin ilmu tanah, ilmu geografi, dan ilmu kartografi, tetapi sekarang berkembang dikaji oleh disiplin ilmu lingkungan, ilmu iklim, ilmu statistik, serta ilmu teknologi dan informasi. Kajian sumberdaya lahan yang awalnya untuk kepentingan ilmu pertanian kini menghadapi problem yang lebih luas seperti perubahan iklim, krisis energi, keanekaragaman hayati, keseimbangan ekosistem, hingga perkembangan kota. Pada era ini perjumpaan ilmu tanah dengan disiplin ilmu lain tidak dapat dihindarkan karena telah menjadi keniscayaan untuk melayani kepentingan umat manusia yang lebih luas. Berkaitan dengan itu istilah ?skala? yang digunakan pada disiplin ilmu tanah, ilmu geografi, dan ilmu kartografi seringkali membingungkan ketika berjumpa dengan istilah ?skala? pada kajian sumberdaya lahan kontemporer. Skala dapat dipahami dalam beragam konteks: 1) skala informasi pada peta, 2) skala level pada berbagai proses, dan 3) skala pada angka pengukuran. Tiga konteks skala tersebut belum termasuk skala pada dimensi lain yaitu skala waktu yang tidak akan dibahas pada artikel ini. Abstract. At present the issue of 'scale' becomes important to be rediscussed by scientists in land resources community. Initially, land resources were only studied by the limited disciplines, such as soil science, geography, and cartography, but now it is studied by the disciplines of environmental science, climate science, statistics, and technology and information science. At the beginning, the study of land resources was to support agricultural science, but at the present the study is to addresss broader problems such as climate change, energy crises, biodiversity, ecosystem balance, and urban development. In this era, the encounter of soil science with other scientific disciplines is inevitable because it has become a necessity to serve the broader of humanity interest. Related to that issue, the term of 'scale' used in the disciplines of soil, geography and cartography is often confusing when meeting to other different disciplines. There are at least 3 different contexts that use the term 'scale' in contemporary land resource studies i.e : 1) scale of information on maps, 2) scale of levels in various processes, and 3) scale of measurement numbers. These three contexts of scale are not included scale of time another dimensions that will not be discussed in this article.

Recently planting site of sugarcane was shifted from lowland to upland area. Sugar cane cultivation in upland has many constraints, especially limited water supply and low nutrition availability. The objectives of this research were to study the influence of application of composted filter cake on growth and water use efficiency of upland sugar cane. The research was conducted in Jengkol, Kediri. Treatments consist of three factors: frequency of irrigation (once every 1 week, once every 2 weeks, and once every 3 weeks); sugarcane varieties (PS-862 and PS-864); and compost doses (0, 2.5, 5, and 7.5 ton ha-1). Split plot design with three replications was used in each irrigation treatment, using composted filter cake as main plots and sugarcane varieties as sub plots. The results showed that the highest sugar content was reached at application of 5 ton ha-1 compost and the greatest crystal sugar was reached at 3.09 ton ha-1 compost. Compost application at 5 ton ha-1 on each planted row can reduce frequency of irrigation from once a week to once every 2 weeks.

Results of the study on morphological, physical, and chemical characteristics of three pedons developed on volcanic materials of Mt. Galunggung, namely BM1, 8M2, and 8M3, showed that these pedons had a different stage of profile development. Pedon BM1 is classified as undeveloped, 8M2 is medium developed, and 8M3 is strongly developed. This is mainly caused by differences in the relative age of the parent rocks and elevation. Although classified as undeveloped, the soil represented by pedon BM1, the youngest, has immediately been used by farmers for rice cultivation because of water abundance, and high availability of P, and basic cations derived from weathering of easily weathered amorphous materials and minerals. According to the Soil Taxonomy system of the USDA (Soil Survey Staff, 1996), pedons 8M1, 8M2, and 8M3 are classified as Typic Udipsamment, Taptho Hapludandic Typic Troporthent, and humic Hapludult, respectively. Whilst, according to the FAO/UNESCO system (1988), these pedons are classified as Eutric Regoso/, Eutric Regosol and Humic Aliso/, respectively.

Micromorphology is a branch of science in soil science. In micromorphological studies, soil samples are first prepared as a thin slice (with various methods), then the phenomena inside are examined using a microscope. By knowing the composition, shape, orientation, distribution patterns, structures, etc., the phenomena that occur can be interpreted, both regarding the composition of the soil, the relationship between components and the dynamics of the process that has been, moderate or expected to occur in the soil. Thus, micromorphology can and is very prospective to be developed and applied for various uses outside the field of soil science.

In order to increase service performance of government agencies, the stakeholders have to pay attention to the satisfaction of the public it serves. This study aimed to determine the level of public satisfaction and further willbe analyzed the gap between service performances of the agency and public satisfaction to the service of Land Office of Bekasi City. This research was conducted at the Land Office of Bekasi City; held from March to June 2014. The design used in this study was a cross-sectional study. The samples were chosen by convenience sampling technique. Analysis of the gap was measured by Importance Performance Analysis (IPA). The results showed that the quality of land registration services that was provided by the Land Office of Bekasi City had not meet people's satisfaction. This was indicated by the difference between the average score of the service performance (3,22) and an the average score of the expectations (3,77). This finding showed a gap of -0,55 that means the service performance of the agency still lower that public expectation for the services. Moreover, punctuality was indicator that that had high gap score between the service performance and public satisfaction. Therefore, Land Office of Bekasi should have a policy to discipline its employees to be on time in service of land registration.
