“…t-test is 0,000 smaller than the apha value, there was a rejection of the hypothesis (H1 accepted) meaning that the use of the costs cultivated by the landless farmer group and the traditional farmer group there were significant differences. The use of high costs in the land without burning method is one of the reasons farmers continue to maintain traditional methods / land fires (Subiksa et al 2009;Mustopa et al 2018;Sudirja et al 2018). Efforts to increase farmers' income from a farm, in general are very dependent on the large amount of production costs, especially for the supply of land, seeds, fertilizer and labor, all of which are very influential on the size of the income and income that farmers get from their farming (Purwanto et al 2015).…”

The study aims to analyze the differences in the development of corn cultivation in peat soils between no-burning and traditional methods or with burning in Rasau Jaya District, Kubu Raya District. The fact that currently clearing forests is still using burning on agricultural land in general and especially on peat soil that is feared to experience underground burning is difficult to overcome and cause many losses. The development of corn on land without burning on peat soil is a solution for the community in maintaining ecosystem sustainability. The explanatory research is directed at testing hypotheses and following research objectives. Data collection by interview and questionnaire to 60 respondents were corn farmers on peat soil. The average difference test is used in explaining the difference in yield between the two methods of planting on peat soil. The results found that there were significant differences in the application of corn cultivation on peat soil without burning compared to the traditional method on the variables fertilizer, pesticide, business costs, and yields. In contrast, the planting area variable had no significant difference.

“…Inceptisol has a less fertile soil properties, including a slightly acidic soil pH, moderate C-organic levels, and low NPK nutrients [2]. Low soil fertility, high acidification, high clay content, and easy to leaching in the top soils is the limiting factors of Inceptisol [3].…”

This research was carried out in two stages, three replications. The first stage was to determine the effectiveness of NPK 26-12-12 fertilizer on the yields and quality of corn. Corn with the best quality obtained from the best treatment of fertilization results at the first stage, was used as raw material in the second stage; namely noodles production. The second stage was to determine the quality of corn noodles. The factors that were used in the first stage were the combination dose of NPK 26-12-12 + urea + KCl which was compared to NPK 15-15-15 + urea + KCl (there are nine treatments). The factors that were used in the second stage was the percentage of corn flour (0; 10; 20; 30; 40; 50; 60%). The results of the first research found that the application of NPK fertilizer can increase the vegetative growth of corn plants, the highest yield was in the G treatment which produced a harvest of 6.94 t / ha; R/C ratio 1.56 and RAE 181. The results of the second research found that the addition of corn flour affected the quality of corn noodles. Panelists like noodles with the addition of 30% corn flour.

“…Manure and biochar application in soil can improve soil quality and crop productivity (Muharam & Saefudin, 2016). Dolomite and guano can also increase soil pH, Organic-C, and bacterial activity (Kusbianto et al, 2014;Sudirja et al, 2017). The composition and dose of these ameliorants need further study, especially for chili plant grown in Inceptisols.…”

Inorganic fertilizers have an important role in improving the productivity of chili plants, but continuous use will cause soil quality to decline. The use of ameliorant is expected to improve soil quality. This experiment was aimed to find out the best effect of ameliorant composition and dose on organic-C, soil pH, population of phosphate solubilizing bacteria, and yield of chili plant in Inceptisols Jatinangor. The research was conducted in plastic house of Agricultural Faculty of Padjadjaran University on January – Mei 2018. The design experiment was factorial randomizedblock design which consisted of two factors with three replications. The first factor was ameliorant composition consisting of four levels (a1 = 80% cow manure + 20% Biochar Coconut Shell ; a2 = 95% Composition a1 + 5% Dolomite and Guano ; a3 = 90% Composition a1 + 10% dolomite and guano; a4 = 85% composition a1 + 15% dolomite and guano), and the second factor was ameliorant dose consisting of four levels (t0 = 0 t ha-1 ; t1 = 2 t ha-1 ; t2 = 4 t ha-1 ; t3= 6 t ha-1). The results showed that there were no interaction between composition and dose of ameliorant to organic-C, soil pH, population of phosphate solubilizing bacteria, and yield of chili on Inceptisols Jatinangor. The 4 t ha-1 of ameliorant dose increased organic-C, soil pH, population of phosphate solubilizing bacteria, and yield of chili plant by 44,9%.ABSTRAK Pupuk anorganik meningkatkan produktivitas tanaman cabai, namun penggunaan terus menerus akan menyebabkan kualitas tanah menurun. Penggunaan amelioran diharapkan dapat memperbaiki kualitas tanah. Penelitian ini bertujuan untuk mengetahui pengaruh komposisi dan dosis amelioran terbaik terhadap C organik, pH tanah, populasi bakteri pelarut fosfat, dan hasil tanaman cabai di Inceptisols Jatinangor. Penelitian dilakukan di rumah plastik Fakultas Pertanian Universitas Padjadjaran bulan Januari – Mei 2018 menggunakan rancangan acak kelompok faktorial terdiri dari dua faktor dengan tiga ulangan. Faktor pertama adalah komposisi amelioran yang terdiri dari empat taraf (a1 = 80% kotoran sapi + 20% biochar batok kelapa; a2 = 95% komposisi a1 + 5% dolomit dan guano; a3 = 90% komposisi a1 + 10% dolomit dan guano; a4 = 85% komposisi a1 + 15% dolomit dan guano), dan faktor kedua adalah dosis amelioran yang terdiri dari empat taraf (t0 = 0 t ha-1 ; t1 = 2 t ha-1 ; t2 = 4 t ha-1 ; t3= 6 t ha-1). Hasil penelitian menunjukkan bahwa tidak terdapat interaksi antara komposisi dan dosis amelioran terhadap C-organik, pH tanah, populasi BPF, dan hasil cabai pada Inceptisols Jatinangor. Dosis amelioran 4 t ha-1 meningkatkan C-organik, pH tanah, populasi BPF, dan meningkatkan hasil tanaman cabai sebesar 44,9%.
