Abstract

ABSTRACTAt Rurukan sub-district dry farming agricultural a large part contrived on region gets to bevel. On runoff scarp will happen faster, it because rainwater which falls will be adrift at presto surface soil, so water chance for turns in at earth as laconic and make infiltration capacity become little. Therefore needs to be done by soil conservation action as makings of terrace for earth preservation. There is aim even of this research which is to know big runoff on barrackterrace and traditional barrackon about carrot plant at Rurukan sub-district. This research doing to utilize fairish little slot method 11x4 meter. Downloading is done begin over carrot until crop instilling, data then described by descriptive point out observational result that runoff on barrackterrace slot which is 0,14 m 3 / barrackslot and slot traditional as big as 0,00 m 3 /slot.Key word: Runoff, Terrace, Compost, Rurukan

Abstract

ABSTRACTThis study aimed to know physical land suitability for soybean crops in the Pandu Village, Mapanget District of Manado. This research can provide input and information to the government and the people of the district of Mapanget about land suitability, especially for soybean plants, which were held at Pandu Village, Mapanget District of Manado city, and at the Laboratory of Soil Conservation and Physics, Faculty of Agriculture of Unsrat for 6 ( six ) months, commencing from March to August 2013, by using the method of Land Survey Unit Approach. The results showed that, the agricultural land at Pandu Village has some potential areas for development of soybean plants. Area I and VI were categorized into suitability classes S2 ( quite appropriate ), Area II was the suitability class S3 ( marginally suitable ), Area III was suitability class N1 ( not appropriate at this time ), Area IV were conformity classes N2 ( not appropriate forever )Keyword: Physical Land Suitability, Soybean

Abstract

Abstract The objective of this study aims to determine the value or the value of soil erodibility K at various heights along the road Manado - Tomohon. The metode used in this research is the method of stratified random. Analisis soil texture using a pipette. The data is then inserted in the soil texture triangle K values for determining the K value of the land at any altitude. Things are observed is 1). Slopes, 2). land use, 3). Soil texture, and 4). K Value. The data obtained in terms of three grades K arranged in tabular form to determine the value of K dignity and then described descriptively. The results showed that at altitude: 1). 200 m above sea level K value of 0.379; 2). 300 m asl K value of 0.393, 3). 400 m asl value amounted to 0,384 K, 4). 500 m above sea level K value of 0.397, 5). 600 m asl K value of 0.376, 6). 700 m above sea level K value of 0.370, and 7). 800 m asl K value of 0.430. Based on the K value obtained at each altitude or soil erodibility K values are rather high. Keywords: Erodibility Land (K), High Places

Abstract

ABSTRACT The study aims to identify the occurrence of mass movement in the village Rumengkor and calculate the volume of soil that experienced mass movement in the village Rumengkor. The research was carried for three months from June to August 2014. Research using survey method with the method of design through several stages which includes the identification of mass movement through the inventory and analysis (taking into account the secondary data and primary data darihasil laboratory analysis and the results of field measurements), then calculate the volume of soil that is moved through the tread design drawings. The identification results of the mass movement of land in the village of Rumengkor shows there has been a process of disengagement from the connective power (cohesion) soil / rock and roots are weak so that the granules soil / rock can be released from his bonds and then a process of transporting / moving to the bottom of the slope by dragging Other grains around it to form a larger mass and settles on the bottom of the slope (98m). Weak holding capacity soil / rock can be caused by a rock that is not compact, the physical properties of the dominant clay soil texture, water break-out properties (permeability) moderate to fast which is supported by high rainfall, the ground cracks, the scarcity of ground cover plants and Volume space land of productive land are lost as a result of mass movement in the village of Rumengkor calculated from the movement of the tread design perspective 7199.25 m3.  Keywords : Land Mass, Cohesion and Permeability

Abstract

ABSTRACT  The research on soil tailing was conducted to know its potency for corn (Zea may L.). It was arranged in descriptive survey descriptive methods and laboratory analysis for soil texture, permeability, total N, available-P and available-K, organic-C and soil pH.  Data analysis was done by matching the soil tailing characteristics and the criteria of land suitability for corn.  The result showed that the tailing was potencial for corn growth.  Keywords: Soil tailing, Soil potency

Abstract

ABSTRACT Compost is a product of decomposition of organic materials accelerated by various microbes to become weathered. This study aims to examine the change of soil chemical properties of the gold mine soil before and after the application of soil composting materials. The research method used is descriptive from the analysis of soil chemical properties such as : Color, pH, C-Organic, N, P, and K. Parent material of gold mine soil generally have pale yellow color, low pH  (acid), C-organic , N, P, and K are not ideal or low. The condition of the mine ground material is in the phase of damage. Soil ameliorant are natural or synthetic materials used to cope with soil damage. Compost is one of the organic soil ameliorant with the function of improving the condition of damaged soil and also as a source of nutrients. Compost will give changes to the gold mine soil material but not quickly, it takes a relatively long time.  Keywords: Compost, Soil ameliorant, Material of Gold Mine Ground.

Abstract

Abstrak  Penelitian ini bertujuan untuk mengetahui kelas kesesuaian lahan tanaman kedelai di sebagian wilayah Desa Sea dan Warembungan, Kecamanatan Pineleng. Penelitian ini dapat memberikan informasi kepada pemerintah dan  masyarakat Desa Sea dan Warembungan Kecamatan Pineleng Sulawesi Utara tentang kelas kesesuaian lahan  untuk tanaman kedelai beserta factor-faktor pembatas dalam pengelolaan tanaman ini. Penelitian ini dilaksanakan selama 6 (enam) bulan, terhitung sejak bulan Februari sampai Agustus 2018, dengan menggunakan metode survei melalui pendekatan unit lahan. Dalam penelitian ini, satuan lahan diperoleh dari hasil tumpang susun antara data penggunaan lahan, data kemiringan lereng. Data karakteristik lahan diperoleh dari pengamatan lapang dan hasil analisis sampel di laboratorium.  Teknik pengumpulan data berupa  observasi/pengamatan tanah di lapang dan analisis laboratorium. Teknik analisis data untuk mengetahui kelas kesesuaian lahan menggunakan sistem informasi geografis, yaitu dengan perangkat lunak ArcGIS 10.3 sehingga didapatkan peta kesesuaian lahan tanaman kedelai di sebagian wilayah Desa Sea dan Warembungan Kecamatan Pineleng. Hasil penelitian menunjukkan bahwa lokasi penelitian dengan luas 584,61 Ha yang merupakan sebagian Wilayah Desa Sea dan Warembungan  Kecamatan Pineleng memiliki enam unit lahan. Unit-unit lahan ini mempunyai potensi untuk pengembangan tanaman kedelai. Secara aktual lokasi ini memiliki kelas kesesuaian  N (Tidak Sesuai) dengan faktor pembatas curah hujan, bahaya erosi dan kedalaman efektif. Namun, secara potensial lokasi ini memiliki kelas kesesuaian lahan S3 (Sesuai Marginal) apabila dilakukan  usaha-usaha perbaikan seperti saluran drainase, pembuatan teras dan penanaman tanaman penutup lahan.  Kata Kunci : Kesesuaian Lahan, Kedelai, Sistem informasi Geografis
