Abstract

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.

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%.

Abstract

Rice (Oryza sativa L.) has become one of the main food crops in Indonesia. Rice productivity plays an important role for the supply of the community on a national scale. The application of NPK fertilizer can be a solution. The objective of this study was to determine the response of NPK compound fertilizer “Compaction DGW” on rice yield. The experimental was design using a Randomized Block Design (RBD) that consisted of 3 treatments and 3 replications, on 2,5 m x 4 m (10 m2) plot. The NPK compound fertilizer used for this study was “Compaction DGW”. The treatments included K0 (control), A2B1 (200kg of NPK fertilizer + fertilizer grain size > 1 mm), and A2B2 (200 kg/ha NPK fertilizer + fertilizer grain size < 1 mm). The variable observed was the production of dry grain. The results showed that the application of NPK compound fertilizer “Compaction DGW” with grain size >1mm and <1mm had no significant effect on increasing the dry grain weight. However, NPK compound fertilizer “Compaction DGW” produced higher dry grain weight compared to the control.

Abstract

The purpose of this study was to determine the availability status of N, P, and K nutrients in tomato-planted land, which serves as the basis for fertilizer recommendations for tomato crops. The research was carried out over 8 months. The tools used included shovels and laboratory equipment for soil analysis. The materials used were dryland soil and chemical reagents according to the methods of soil analysis for N, P, and K. The research method employed a survey approach with composite soil sampling at 6 locations, adjusted to the actual soil conditions in the field. Condition 1: Soil that had been prepared and was ready for planting. Condition 2: Soil planted with tomatoes aged 1 month. Condition 3: Soil that had just been harvested, with tomato plants aged 3 months. From each soil condition, 3 soil samples were taken, resulting in a total of 9 samples. The research duration was 8 months, from preparation to the final report. Soil samples collected in the field were analyzed in the laboratory to obtain quantitative results. Nitrogen content was analyzed using the Kjeldahl method; available Phosphorus content was analyzed using the Bray I method; available Potassium content was analyzed using the Bray I method. The data obtained from soil analysis showed that Nitrogen levels were classified as moderate, available Phosphorus levels were moderate, and Potassium was sufficiently available for plant needs.
