Abstract

This research aimed to determine the effect of air circulation treatment toward cow manure sludge fermentation process and to determine the quality of sludge that was produced accordance to Indonesia National Standard (SNI) of Compost No. 19-7030-2004. The air circulation treatment was done by using aerator. There were three combination treatments of air circulation: the aerator and drum with coat, aerator and drum without coat, and without aerator and drum without coat was applied as a control. The results of this study indicate that each treatment in the fermentation process had a different temperature fluctuations between 21.56 to 24.41 °C. Temperature is a requirement for mesophilic microbial growth. The acidity condition of the sludge material at the beginning until the end of fermentation was the whole treatment has fulfilled the optimal conditions of fermentation process, with range of pH was from 6.92 to 7.65. The influence of air circulation inside the drum without the coat of rice husk can accelerate the breakdown of proteins into C-organic and N-total, that was C-organic= 24.22%, and N-total = 1.80%. The compost that produced by the fermentation process had the characteristic ratio C / N = 13.46 and had a blackish brown colour rendition. Characteristics of compost according to the quality of compost SNI No. 19-7030-2004, that is pH = 6.80 to 7.49, C-organic = 9.80 to 32%, N-total = 0.40%, the ratio of C / N = 10-20.

Abstract

An experiment on biourine fermentation using cow urine has been carried out. The objective of this research was to optimize biourine fermentation by adding starter and palm sugar. The reseach used Completed Randomized Block Design with factorial pattern of 2 factors and 3 levels each. The first factor was starter concentrations of Rumino bacillus 0, 15, and 30 ml. The second one was weight of palm sugar added at 0, 15, and 30 g. Each treatment was repeated 3 times. Varibles observed were pH, acid, soluble solid, organic C, and total N. Results of the research indicated that starter addition of 15-30 ml and palm sugar 15 -  30 g for every 1500 ml cow urine accelerated biourine production in the fermentation stage of cow urine which was taken from simantri number 225. The fermentation process was carried out for 7 days and by adding this combination of traitment shortening the process to 5 days. This was shown by pH,total acid,and total dissolve solids value of urin which was stable after 5 days of fermentation. Concentration of 30 ml R. bacillus with the addition of 30 grams brown sugar in 1,500 ml of fermented cow urine is the optimal treatment in which the value of pH is 6, 0.5% total acid, and 3.80Brix total dissolved solids. This is supported by the standard of Permentan Number 70 with a pH value of 4-9. However, the research for C-organic and N-total has not fulfilled the standard of Permentan in which the C-organic is 6% and N total is 3-6%.

Abstract

Crop residues such as supreme variety rice straw can reach about 25 ton/ha which can be used as raw material for composting. The purpose of this research were to determine the effect of channels aeration of the composting process, and to find the compost quality produced from rice straw. Two treatments were conducted, namely: P1 : rice straw composting with aeration channel; P2 : rice straw composting without aeration channel. About 1.5 m long, 1 m wide and 1 m high of dimension of compost heap respectively were conducted. The parameters measured were temperature, humidity, water content, yield, pH, nitrogen, carbon and C/N ratio. The composting process lasted for 12 weeks. The composting process in the composting treatment with aeration channels tend to run slower than composting treatment without aeration channels. The quality of the compost produced from rice straw on the treatment P1 and P2 were appropriate the standard compost appointed by Peraturan Menteri Pertanian Nomor 70/Permentan/SR.140/10/2011.

The purpose of this research was to get a prototype of a maize planters and fertilizer that can simplify work of farmers in the cultivation of maize, especially planting and fertilizing in one work process. The method used in this research is to create a prototype of a planter and corn fertilizer semi-mechanical that tested on 100 m2 of land no-tillage with flooded conditions 2-3 days before planting at a spacing of 25 cm in a row and 75 cm between rows. The results of the test show that the average output of corn was 2 seed to each hole and 31-40 grams fertilizer with a success rate of 86,88 % and 95 %, effective field capacity 0,0122 ha/hour, theoretical field capacity 0,0135 ha/hour and the speed of planting was 12 hole/minute.

Abstract

Cow urine has the potential to become biourin. This study aims to determine the effect of the type of diffuser on the quality of biourin, as well as to determine the best type of diffuser during the fermentation process. This study used a completely randomized design consisting of 5 treatments and 3 replications. Each treatment contained 10 liters of urine, 2% nitrifying bacteria, and 2% molasses. The treatment was carried out without aeration, treatment using aeration without a diffuser, treatment using a fine bubble diffuser, treatment using a coarse bubble diffuser, and treatment using an aerated stone diffuser. This fermentation was carried out for 20 days with measurements every 5 days. Parameters observed were temperature, pH, TDS, EC, C-Organic, N-Total, and C/N Ratio during the fermentation process. The results of the study showed that the use of several types of diffusers had a significant effect on the process of fermenting cow urine. The fermentation process without using a diffuser showed that as the fermentation time increased, the pH value decreased from 7.72 to 7.54. On the 20th day of bio-urine fermentation, the highest Biochemical Oxygen Demand value was shown by the treatment using a fine bubble diffuser with a value of 9.2 mg/l. Of the five urine fermentation treatments, only fermentation with a diffuser met standard No.70/Permentan/SR.140/10/2011. Treatment with a type of fine bubble diffuser is the best treatment.

Abstract

Rice is a staple food for the people of Indonesia. Even though Indonesia is an agrarian country, Indonesia currently imports rice. In producing rice from rice there are obstacles. One of the main obstacles is post-harvest handling of rice with high yield loss during post-harvest. The amount of post-harvest loss occursbecause most farmers still use traditional method or the handling is not good and right. The purpose of this study was to determine the relationship between the capacity of the grinding machine and the quality of sosoh rice produced by the mill and to know the quality comparison of various types of grinding machine capacity. The research was carried out in the area of Wanasari Village, Tabanan - Bali to find out the quality of sosoh rice in the region. Head Rice is broken rice grains, both healthy and defective, which have a size greater than or equal to 6/10 part of the average length size of whole rice grains that can pass through the surface of the indented plate basin with a requirement of 4.2 mm hole size. Rice hull is a protective cover from rice grains which is separated from seeds during the grinding process. In the grinding process, there is rice which remains the husk which is caused by the power / rpm of the grinding machine which is too low because the friction force produced by the engine is not sufficient for the overall release of rice hull
