Abstract

ABSTRACT This study aimed to determine the class of land capability, land using, and conservation technique which could be applied at Tondano tuff derived soils along Belang-Ratahan road. The results showed that, four  classes of  land capability, were: a)  class III at 100 m (Watulinei), 200 m, and 300 m (Wawali) above sea level; b) class IV at 400 m (Lowu II) and 600 m (Pangu) above sea level; c) class VI at 700 m above sea level (Pangu), and  d) class VIII at 500 m and 800 m above sea level (Pangu). Most of the land using were not suitable, yet and there were no soil and water conservation technique applied, yet. Only at 700 m and 800 m above sea level that have been used suitable  as the nature reserved. Keywords: land capability, Tondano tuff

Abstract

AbstractWori districts which has an area of 90.704 km2 is one of North Minahasa district that processed into oil palm plantations, coconut flour, nata de coco, coconut shell charcoal and coconut trees. Coconut flour is one of the oil derivative products (integrated coconut) recorded the many buyers and scattered in almost all parts of the world. Buyers of coconut flour was more focused on Eastern Europe, but is now rapidly spreading evenly over all the continents in the world. Anticipate in terms of availability of coconut flour it is necessary to the development of the coconut crop, given the current availability of old coconuts began to decrease. This study aims to determine the potential of land for coconut (Cocos nucifera L) in District Wori North Minahasa regency. This research can provide input and information to the government and the people of North Minahasa district Wori in coconut planting efforts. The research was conducted in the District of North Minahasa regency Wori, and in Laboratory Soil Department of Faculty of Agriculture, University of Sam Ratulangi Manado. This study was conducted in July 2009 and September 2011. Research methods implemented by way of a survey method with land unit approach, the observed variable is the slope, effective depth, texture, erosion, drainage, soil type and land use. The data were then arranged in tabular form later described descriptive to determine appropriate land or potentially and inappropriate or potentially for coconut by coconut trees growing conditions The results showed that in the region have Wori climate types B1, namely: 7-9 wet months and <2 dry months. Wori altitude region is 0-610 meters above sea level with the form region is rather flat, undulating to mountainous. Slopes in the study area is dominated by slopes <15%. Wori soil characteristics in the area, where the physical and chemical properties of the soil, namely: effective depth, texture and drainage and soil pH, indicating that the soil in the area has the potential to Wori Based on comparison of coconut and palm trees growing conditions with the conditions of the study area Wori region potential for development of coconut plantations with a total area of 4637.80 ha

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

Penelitian dilakukan di rumah kaca bertujuan untuk mengetahui pengaruh pemberian pupuk NPK compaction DGW terhadap pertumbuhan dan produksi padi sawah. Penelitian menggunakan rancangan percobaan Rancangan Acak Lengkap (RAL) pola Faktorial AxB di mana faktor A adalah dosis pupuk NPK Compaction DGW yang terdiri dari 4 taraf dosis (A1= 0 kg/ha; A2 = 100 kg/ha; A3 = 200 kg/ha; A4 = 300 kg/ha) dan faktor B adalah ukuran butir pupuk yang terdiri atas 2 taraf (B1 = > 1 mm; B2 = < 1 mm). Diulang tiga kali, sehingga terdapat 24 pot percobaan. Variabel yang diamati adalah: tinggi dan produksi tanaman padi. Hasil analisis statistik dari delapan kombinasi perlakuan yang diteliti menunjukkan bahwa tidak terdapat perbedaan yang nyata dari semua perlakuan. Tetapi terdapat kecenderungan perbedaan tinggi tanaman dan produksi tanaman padi pada perlakuan yang diujikan. Dosis dan ukuran butir pupuk yang sesuai terdapat pada pelakuan A2B2. Hasil penelitian juga memberikan petunjuk bahwa pemberian pupuk NPK Compaction DGW yang dihaluskan memberikan hasil yang lebih tinggi dibandingkan tidak dihaluskan sebesar 33,48 %. The research was conducted in a greenhouse with the aim of determining the effect of NPK compaction DGW fertilizer on the growth and production of paddy fields. The research used a Completely Randomized Design (CRD) experimental design with the AxB Factorial pattern where factor A is the fertilizer dose of NPK Compaction DGW fertilizer consisting of 4 dose levels (A1 = 0 kg / ha; A2 = 100 kg / ha; A3 = 200 kg / ha; A4 = 300 kg / ha) and factor B is the size of the fertilizer grains consisting of 2 levels (B1 = > 1 mm; B2 = < 1 mm). Repeated three times, so there were 24 experimental pots. The variables observed were: height and production of rice plants. The results of statistical analysis of the eight treatment combinations studied showed that there were no significant differences between all treatments. However, there was a tendency for differences in plant height and rice production in the treatments tested. The appropriate dose and size of fertilizer grains can be found in the A2B2 implementation. The results of the research also provide indications that applying finely ground NPK Compaction DGW fertilizer gives higher results than not grinding it by 33.48%.
