The objectives of the study are: 1) to determine the composition of the original cocoa bean pulp as a substrate for fermentation; 2) evaluating the effect of variations in random cocoa bean fermentation techniques on microbial populations. The stages of research carried out are as follows (1) testing the composition and moisture content of asalan cocoa beans as a fermentation substrate. (2) Fermented cocoa beans with 3 variations of fermentation techniques namely first treatment without addition of inoculum (control), second using S. cerevisiae (FNCC 3056) inoculum, L. lactis (FNC 0086) and A. aceti (FNCC 0016), respectively. - about 108 cfu / g is given simultaneously at the beginning of fermentation (IA). (3) gradual administration of inoculum yeast at the beginning of fermentation, lactic acid bacteria at 24 hours and acetic acid bacteria at 48 hours with a microbial population equal to the second treatment (IB). Fermentation is carried out for 120 hours. The temperature is set during fermentation, respectively 35 oC (first 24 hours), 45 oC (second 24 hours), 55 oC (third 24 hours) and 35 oC (last 48 hours). The results showed that during the fermentation of random cocoa beans showed that all treatments increased ethanol consumption in line with the increasing population of S. cerevisiae at the beginning of fermentation. Furthermore, L. lactis increases followed by lactic acid, at the end of A. aceti fermentation increases with acetic acid. From the results of this study it can be concluded that the rehydration of asalan cocoa beans can improve the composition of the pulp as a fermentation substrate. Microbial population shows that microbial succession has been demonstrated by the gradual addition of the inoculum.

The Farmer Exchange Rate (FER) is one of the indicators in determining the welfare level of farmers. Every month this large FER has a change especially at the end of each season during harvest, the price game especially from producers often occurs so that not a few farmers complain and suffer losses. Therefore, there need to be efforts from the government is looking at past data trends to find the amount of FER in the future so that policies can side with farmers. Artificial Intelligent with a multilayer Back Propagation method is very good for modeling and forecasting of data series in the past with data input in the form of a matrix mxn. The simulation results show that in 2020 in NTB there is an average increase in the exchange rate of farmers of 118.76%, this means that farmers are experiencing a surplus or farmers’ incomes are rising more than their expenditures. However, it appears that from June-August and October-November there was an average decrease of 2%, although overall...

A major challenge in simulating chemical reaction processes is integrating the stiff systems of Ordinary Differential Equations (ODEs) describing the chemical reactions due to stiffness. Thus, it would be of interest to search systematically for stiff solvers that are close to optimal for such problems. This paper presents an implicit 3-Point Block Backward Differentiation Formula with one off-step point (3POBBDF) for the solutions of first-order stiff chemical reaction problems. In deriving the method, the Lagrange polynomial was adopted as the basis function. The paper further analyses the basic properties of the 3POBBDF which include order of accuracy, consistence, zero-stability, and convergence. The stability region as well as the interval of instability of the method was also computed. To demonstrate the accuracy of the proposed approach, some famous stiff chemical reaction problems such as Robertson problem and Chemical AKZO were solved, and the results obtained were compared...

Nurseries rely on soilless substrates to provide suitable growing media for container grown crops. These soilless substrates have been developed to readily drain water to prevent issues with waterlogging and associated soil-borne disease. A negative consequence of high porosity and subsequent drainage throughout the container profile is the required high or frequent irrigation rates with poor retention of applied nutrients. Substrates with relatively high levels of moisture and nutrient retention placed on top of a coarse and freely draining substrate could further optimize water and nutrient retention, while allowing for needed gas exchange for plant establishment and growth. Containerized Red Drift® rose (Rosa ‘Meigalpio’ PP17877) plants were grown under 16 mm or 12 mm daily irrigation, utilizing a traditional pine bark substrate or stratified substrates with either a conventional bark, bark fines, or a bark–peat mixture on top of a coarse bark within a container.

Dolomitic lime (DL) is the primary liming agent used for increasing pH in peatmoss-based substrates. Steel slag (SS) is a byproduct of the steel manufacturing industry that has been used to elevate field soil pH. The objective of this research was to determine the pH response of a peatmoss-based greenhouse substrate to varying rates of DL or SS. Two experiments were conducted with an 85 peatmoss : 15 perlite substrate. In the first experiment, the substrate was amended with 0, 2.4, 4.8, or 7.1 kg·m−3 of either DL or SS. Half of the containers remained fallow and the other half were potted with a single sunflower (Helianthus annuus L. ‘Pacino Gold’). In the second experiment, fallow containers were only used with the substrate amended with 0, 2.4, 4.8, 9.5, or 14.2 kg·m−3 DL or SS. Sunflower were measured for relative foliar chlorophyll content, shoot mass, root ratings, and foliar nutrient concentrations. Substrate electrical conductivity (EC) and pH were measured weekly using the p...
