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

Fly ash and bottom ash are waste produced from burning coal in the Steam Power Plant industry. The higher the coal consumption, the higher the FABA waste produced. However, despite the abundant production, this waste has not been optimally managed and utilized. This research aims to determine the effect of using FABA as an ameliorant in planting media for tomato plants. This research used the Completely Randomized Design (CRD) method which consisted of 3 treatments with repetition 4 times to obtain 12 experimental units (polybags). The results of the research indicate that the use of coal waste, namely fly ash and bottom ash as an ameliorant in planting media, has a significant influence on plant height, number of flowers, number of fruits, and fruit weight of tomato plants. Planting media with a composition of 50% soil plus 50% fly ash (treatment A) yielded the lowest results among the three treatments. Meanwhile, the planting medium composition of 50% soil plus 50% bottom ash (treatment B) yielded the best results, exceeding the use of 100% soil (treatment O/control). Bottom ash as an ameliorant has a positive influence on the growth and production of tomato plants.

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.
