Abstract

The impact of covid-19 pandemic, has become a complex and actual phenomenon, particularly for Indonesian people and more than 200 affected countries. Currently, 22 countries have experienced economic recession. Planting vegetables with hydroponic and organic systems is still considered difficult and not widely known by many people. Parents of the students and the surrounding community helped grow vegetables in the Pesantren (Islamic boarding school) and in their homes after participating the training and vegetable crop grants, in PPTQ Nuurun ala Nuur. Therefore, it is necessary to conduct research on the level of community participation, thus their participation can be increased to become a resilient village, towards a city and Indonesian nation that is resilient to the impact of COVID-19 pandemic. The purpose of this study is to describe, analyze and interpret; (1) the form of community participation (2) the degree of community participation, and (3) the typology of community participation in planting vegetables in Islamic boarding school and in their respective homes. This study used a qualitative approach, collecting data with interview techniques, questionnaires, observation and documentation. Data analysis used interactive techniques from Milis and Huberman. The validity of research data used trustworthiness, transferability, dependence and certainty. The results of this study include: (1) The process of community group discussions, (2) Community empowerment, (3) Utilization of community outcomes in health, economy and environment towards a COVID-resilient society, (4) The degree of spontaneous participation, (5) The degree of induced participation, (6) The degree of depressed participation, (7) The degree of economic participation (8) The role of intensive participation, (9) The role of functional participation and (10) The role of community participation independently

Abstract

The downstream of DEA surfactant products has great potential in the industrial world, one of which is agricultural product in the form of insecticides. The purpose of this study is to examine the scale multiplication of insecticide products for the brown planthopper on a pilot scale of 25 l and an industrial scale of 1000 l and calculating the selling price of insecticide products with different profit variations based on the cost of production. The scale multiplication was based on the unit of power per unit volume (Pg /V) which had a fixed value. The optimal agitation speed in product formation was obtained from a small-scale experiment, and the results were used to obtain the agitation speed on a large scale, which required the same power per unit volume. A simple step to calculate multiplication of the scale was by using the basic geometric shape of the tools used in the process performed. The determination of the tools used was based on the effectiveness of the two types of tools, namely mixer and homogenizer. Furthermore, the multiplication of the scale into geometric shapes on the scale of 25 l was carried out and continued on the scale of 1000 l. The required parameters in determining the geometry of the reactor were impeller diameter (Di), tank diameter (Dt), sample of liquid height (HL), impeller rotation (Ni). The results obtained showed that the effectiveness of insecticide production was higher in the use of this type of homogenizer tool. In this study, the power per unit volume (Pg /V) was fixed. Calculation data obtained from the laboratory scale include Ht; HL; Di and Dt. On the scale of 25 L were 28.2; 19.5; 12.2 and 33.6 cm, meanwhile on the scale of 1000 L were 95.7; 66.9; 41.7 and 115.4 cm. The result of the calculation of the impeller rotation speed at a scale multiplication of 1000 L was 396 rpm. The calculation of the selling price of the brown planthopper insecticide per bottle (200 ml) for the 50% profit margin was IDR 13,043, the 100% profit margin was IDR 17,390 and the 200% profit margin was IDR 26,086.

Abstract

Maize is one of important comodities contributed as food consumption and other bioproducts to the world. As high demand of maize in global must be followed its avalaibility in markets. Decline the post-harvest losses along maize distribution will not only keep the avalaibility in markets, but also solve the food security. One of post-harvest losses causes is pest, especially in maize storage. The temperature treatment to control S.zeamais, a major insect found in maize storage, becomes potential action in order to reduces the post-harvest losses. The aim of this study was to investigate the S.zeamais mortality rate and physical changes of maize kernel under low temperature condition. The S.zeamais was cultured within 4 months before used for experiments. The 2 different low temperature conditions and 1 control treatment were used in this study. The results showed that the temperature of maize kernel was changed, indicated the movement of maize from room temperature to low temperature storage is occurred. Furthermore, the low temperature treatments, the maize moisture content was slightly changed compared to the control treatment. In addition, there is no chilling injury issue to maize kernel. However, the unknown mechanism of S.zeamais protection to the low temperature was found in the Low Temperature I treatment through the finding of hole grain. In the mortality rate, the highest mortality rate was found at Low Temperature II treatment (95.30 ±11.54%). These findings suggests that low temperature treatment could be the action for maize pest management, especially in the storage.

Abstract

The sustainability of hydrogen as an energy carrier depends on the production process and the source of raw materials. The choice of substrate in anaerobic digestion process plays an important role to maximize biohydrogen production because it depends on its availability and the composition of substrate. The purpose of this study is to design and construct a prototype reactor for biohydrogen production and to determine the potential of H2 gas production from anaerobic digestion process. This study uses an experimental research method with three operating temperature variations in the reactor, at the range of thermophilic temperatures, i.e. 55°C, 60°C, and 65°C. The substrate used was POME and cow dung, and the process was conducted in 24 hours which is assumed to be the stage of non-methanogenic within the anaerobic process. From this research, the prototype of continuous stirred tank reactor (CSTR) in batch system was made from acrylic, with a capacity of 6 liters biomass waste. Using the reactor, total biohydrogen gas produced during 24 hours process with cow manure as substrate was 0,0932 gram at 55°C; 0,0307 gram at 60°C and 0,0797 gram at 65°C. While, biohydrogen production using POME as substrate was 0,0645 gram at 55°C; 0,1708 gram at 60°C, and 0,0636 gram at 65°C. These results indicate the potentiality of POME and cow manure to produce biohydrogen gas during anaerobic digestion process.
