Tondano River is the outlet of Lake Tondano hold the important role for the community in the province of North Sulawesi. With the population growth, increasing the need of society to the river, so there are many problems, such as sedimentation. Sedimentation processes occur accompanied with the rise in erosion so there is more erosion discharge waste in the form of sediment contained in estuaries Tondano. The problem now is how the sediment which was originally a waste can be harnessed into something useful, which is used as a planting medium. This study aims to look at the response of composting hyacinth sediment Tondano Watershed indicators corn crop. Randomized Block Design, where as a control S0, S1 compost treated with 10 tons / ha, S2 compost treatment with 20 tons / ha, S3 compost treated with 30 tons / ha. This research was conducted in three groups in order to obtain 12 pot experiment. The observed variables plant height every week, every week the number of leaves, dry weight of plants after harvest. The results showed that giving the water hyacinth compost on Tondano River Sediments influenced on corn growth. The provision of water hyacinth compost with different doses affected the plant height, the number of leaves and dry weight. Â Keywords: sediment, water hyacinth, compost

ABSTRACTThis study aims to determine the effect of giving various types of organic fertilizer tothe growth and production of spinach plants grown on the marginal soil and which type oforganic fertilizer the best is on the spinach plant. This research was conducted at the villageof Kalasey I for the pot experiment and the analysis of soil, manure and compost wasconducted at the laboratory of Soil Physics and the laboratory of Soil Chemistry and SoilFertility, Faculty of Agriculture Sam Ratulangi University of Manado. This research using byRandomized Block Design Method, where A as a control, B a manure of chicken, C a manureof cow, D a manure of pig, E a manure of goat and F as a compost. This study was conductedin 3 groups to obtain 18 pot experiments.The results showed that the application of various types of organic fertilizer on themarginal soil affected the availability of nutrients needed by plants in the growth andproduction of spinach plants in this case the height of the plant, the number of leaves, thefresh weight of the plant and the dry weight of the plant. Manure of goat provides the highestyield for height of the plant, the number of leaves, the fresh weight of the plant and dryweight of the plant.Keywords : Marginal Soil, Organic Fertilizer

ABSTRACTThe response of spinach as an indicator. (Amaranthus tricolor L.) grown on marginal soil givenpalm oil waste (solid) is the aim of this study. A completely randomized design (CRD) consistingof four treatments i.e., P0 (Control), P1 10 tons/ha, P2 20 tons/ha, P3 30 tons/ha in threereplicates were used during three month trials. The observed variables were plant height,number of leaves, and fresh weight of spinach plants.The results showed that the need forappropriate technology application of plam oil solid waste and its soil management systems onmarginal soils can improved the performance of the grown spinachs on this soil. The applicationof palm oil waste (solid) has a significant effect on the growth of spinach plants in terms of plantheight and number of leaves at the age of 3 WAP (Week After Planting) and of 4 WAP.Treatment of 20 tons of oil palm solid per ha gave the highest yield on plant height and numberof leaves. Furthermore, the fresh weight of spinach plants given 30 tons of oil palm solid per hagave the heaviest weight at 4 WAP.Key words : marginal soils, palm oil waste (solid), spinach plants

The specific goals of the field and laboratory research on N, P, and K nutrient content tests in paddy soil in Kalawat District, North Minahasa Regency, are to increase the production of paddy rice plants by investigating and testing the nutrient contents of N, P, and K in rice field soil using a survey method with composite soil sampling that is tailored to the conditions of rice field soil for rice plants in the field. both at the top and bottom with In condition 1. On processed rice fields prepared for planting. 2. In rice fields where one-month-old rice has been sown. 3. In freshly harvested rice fields. Three composite soil samples were acquired for each paddy field soil condition for rice plants, and these samples were blended to create six soil samples (observations). The entire research project, from planning to report development, took eight months. The Paddy Soil Test Kit (PUTS) was used to collect qualitative data from soil samples collected in the field. Later, the soil samples were examined in the lab using the Kjeldhal method for N content, the Bray 1 method for P levels, and the spectrophotometric method for K levels. Tabular descriptive analysis is the method of data analysis that is employed. According to the study's findings, the nutrient content of the rice fields in Kalawat District, North Minahasa, N. is categorized as low to medium. Keywords: Rice plants, Paddy soil, N, P, and K. Abstrak Penelitian tentang Uji Kandungan Hara N, P dan K Pada Tanah Sawah Di Kecamatan Kalawat Kabupaten Minahasa Utara merupakan penelitian di Lapangan dan Laboratorium dengan tujuan khusus yang ingin dicapai dalam penelitian ini adalah Meningkatkan produksi tanaman padi sawah; dengan cara meneliti dan menguji kandungan hara Nitrogen, Fosfor dan Kalium pada tanah sawah, dengan menggunakan metode survei dengan pengambilan sampel tanah secara komposit disesuaikan dengan keadaan kondisi tanah sawah pada tanaman padi yang ada di lapangan. Pada bagian atas dan bagian bawah dengan Kondisi 1. Pada tanah sawah yang telah selesai diolah dan siap ditanami. Kondisi 2. Pada tanah sawah yang telah ditanami padi berumur 1 bulan. Kondisi 3.

Penelitian ini bertujuan untuk menguji pemanfaatan bottom ash sebagai media tanam dengan pemberian pupuk kandang ayam pada tanaman bayam. Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dengan pengulangan sebanyak 3 kali sehingga diperoleh 15 satuan percobaan. Variabel yang diamati setiap minggu adalah tinggi tanaman dan jumlah daun untuk berat segar berat segar tanaman diukur saat panen. Data yang diperoleh dianalisa dengan menggunakan sidik ragam jika ada pengaruh nyata dilanjutkan dengan uju BNT 5%. Hasil Penelitian menunjukkan Pemanfaatan bottom ash sebagai media tanah dengan pemberian pupuk kandang ayam memberikan pengaruh yang nyata pada tinggi tanaman, dan berat segar tanaman tanaman. Hasil uji lanjut dengan menggunakan uji BNT 5 % menunjukkan perbedaan yang nyata antara perlakuan yang diberi pupuk kandang dengan tanpa pupuk kandang pada tinggi tanaman, dan berat segar tanaman. The aim of research is to test the utilization of bottom ash as plant media by giving the chicken manure in spinach plant(Amaranthus), as astudy of waste management in order to preserve the environment. The research has used Completed Random Design in five treatments and three replications in totally 15 pot samples, Variables have observed in every week were plant height and number of leaves, however the fresh weight has measured at the period of harvesting. Data analyses were used Analysis of Variance if there was significantly affected, then continued to BNT 5% test. Results showed that the bottom ash as plant media by giving chicken manure was significant effect. The BNT 5 % test has shown that by giving the chicken manure 30 of t/Ha gave the highest results and significantly affected among all treatments Kata Kunci: Bottom Ash; Pupuk kandang ayam.
