Abstract

Rice policy is an important element in food security. In its control, the government regulates food management through Logistics Affairs Agency of Indonesia (Bulog). This research aimed to examine government policy related to rice problem in Indonesia using descriptive qualitative analysis method through literature study. The policy of fulfillment of rice needs in Indonesia has been done since the beginning of independence until now. The high demand of the Indonesian people on rice commodities caused fluctuations in rice availability which had an impact on the unstable price, plus the unavailability of enough land to increase domestic rice productivity. Rice import activities are being undertaken from several neighboring countries to address the problem, with the largest number of imports occurring in 2011 over the last 15 years, and the least imports occurring in 2005. The government through Bulog controls the stability of rice stocks and prices for producers through basic price instruments, marketing, rice distribution (post-production), and the supply of staples at the consumer level. In addition, the government through the Community Food Business Development (PUPM) launched the Indonesian Farmer Shop (TTI) program that sells foodstuffs, including rice, at low prices. This program is created as a form of solution to the high price of food demand in Indonesia as a result of the length of the supply chain so the food supply system becomes inefficient. The government has also set the highest retail price policy (HET) and cost of goods sold (HPP) as an effort to stabilize the price of major food commodities in Indonesia, including rice. In the application of HET and HPP values have undergone some changes but still can not achieve price stabilization and improve the economy of farmers, especially small farmers. It is advisable that government policies related to HET and HPP through the Regulation of the Minister of Trade should pay attention for actual price fluctuations and should be distinguished based on the quality of rice, so that price stabilization and the desire to promote farmers in Indonesia can be realized.

Abstract

Napier grass is one of lignocellulosic plants that has the potential to be converted as bioethanol due to high productivity and relatively fast harvesting time. However, the problems of processing lignocellulosic plants into bioethanol are the high lignin content and the different lignin structure of each plant. Lignin can inhibit biological agents in accessing cellulose and hemicellulose. Therefore, it is necessary to select and optimize the pretreatment process with the aim of degrading lignin and maintaining the value of the cellulose. This study was conducted to compare the effectiveness of two different pretreatments (biological and alkaline) in degrading lignin. For the alkali pretreatment, lime (Ca(OH)2) was added to the Napier grass substrate using concentrations of 0.05, 0.1, and 0.5 grams/gram, which was then incubated at 23-25 oC each within 6, 24, and 96 hours period. For biological pretreatment, Aspergillus niger spore was used as an agent, which was incubated onto the Napier grass substrate using concentrations of 106, 107, and 108 cells/mL, an optimal temperature of 35oC and within 1, 3, 5, 7, and 9 days period. As a comparison, Phanerochaete chrysosporium was also incubated using a concentration of 106 a temperature of 35 oC within 28 days period. The extracted Napier grass was then analyzed for lignocellulose content, which included hot water soluble, Hemicellulose, cellulose, lignin, and ash, using Chesson-Datta method and reducing sugar test. Comparison of biological pretreatment between Aspergillus niger and Phanerochaete chrysosporium showed that Aspergillus niger was better at degrading lignin, with a lignin-to-cellulose ratio of 24.3%, smaller than Phanerochaete chrysosporium at 30.645%. This ratio was furthermore compared with the ratio resulting from Alkali pretreatment, which showed that the former was proven to be more optimum.

Abstract

West Java is one of the provinces in Indonesia where the staple food is rice. The high ability of rice provisioning  and the government?s encouragement through the policy of uniformed staple food gave a negative impact on rice consumption patterns of West Java population. This pattern of consumption will become a problem when faced with the fact that the rice production area has declined (0.67% per year) and the population increased (1.41% per year).  Based on projection of production and needs of rice, it is predicted that West Java will experience shortages in 2040. Therefore this research aimed to discuss efforts to prevent rice dependency problem. The entire study used case study approach. By using secondary data, basically the government has made many efforts to resolve the problems. In fact, there are some obstacles and the mismatch on results. Therefore the alternative solutions are: a). diversification efforts with rice commodity substitution based on geographical location, b). socialization, c). rice price policy, and c). improved education and economics.

Abstract

Climate change has a negative impact on rice production in Indonesia. This research was conducted to identify problems caused by climate change on agriculture, identify the technology to address climate change, and analyze the technological adaptation to encounter the climate change problems in West Java. Problems arising from climate change include increasing air temperature, rainy season shift, and prolonged drought. The impact of climate change on agricultural land in West Java is prolonged drought and land degradation. The most appropriate technology to be applied in West Java in order to address climate change is System of Rice Intensification (SRI). SRI rice cultivation can save water up to 30% compared to conventional cultivation, so it can be applied when the water resources was limited. SRI method that has been applied in West Java shows that organic rice farming produces more rice than inorganic farming. The productivity of inorganic farming are 6.0 - 7.0 tons / ha, whereas the SRI organic farming could produce 8 - 9.2 tons / ha grain. The application of the SRI method in Cibarengkok Village, Bojong Picung, West Java produces 7-8 tons / ha of grain, while the conventional method yields 4-5 tons / ha of grain.

Abstract

Napier grass is a promising lignocellulosic biomass for bioethanol production because of its high cellulose content and high annual productivity. Converting a lignocellulosic biomass into a bioethanol usually takes two steps which resulted in a long processing time and sometimes includes the utilization of hazardous chemicals. Simultaneous saccharification and fermentation in a solid-state culture using single bioconversion agent, Neurospora sitophila Shear, can reduce the overall processing time and also increase the yield of the products. The research is aimed to determine the optimum aerobic and micro-aerobic conditions that yields the highest enzyme activity and bioethanol concentration from the mixture of Napier grass and soybean curd residue. The saccharification and fermentation process was conducted in the laboratory using an incubator at 33oC. The cellulase enzyme activity was calculated as FPAse. The highest activity achieved was 0.538 filter paper unit with the optimum mass ratio of Napier grass to soybean curd residue was 1:1 on the second day of cultivation period. The fermentation process was conducted aerobically for two days and then followed by six days of micro-aerobic fermentation, resulting in the highest bioethanol yield of 2.12% (w/w) at the end of the culture period. The optimum mass ratio was found to be 9:1. This study shows that Napier grass and simultaneous saccharification and fermentation method has a great potential for cellulase and bioethanol production, but further improvement on the micro-aerobic system is needed to maximize the bioethanol yield.

Abstract

Chromium is one of the heavy metals used in industrial fields, i.e., metallurgical industry, chemical industry, heat-retardant, and leather tanning industry. Untreated wastewater from these industries can pollute rivers and threaten the aquatic ecosystem. Some aquatic plants such as water hyacinth (Eichhornia crassipes) and water lettuce (Pistia stratiotes) have been known as metal hyperaccumulators and can be used as phytoremediator for polluted water. This study aims to determine the physiological and morphological responses of water hyacinth and water lettuce plants treated by different concentrations  of trivalent chromium and to study which plant is effective for trivalent chromium removal. The experiment was conducted for 2 week at screen house. After two weeks, the plants were harvested and the weight was measured. The samples were separated into shoot and root and were analyzed for Cr content, chlorophyll, proline and CAT enzyme activity. The results of this study indicated that the levels of water hyacinth chromium in roots and leaves are lower (863.988 mg/Kg, 899.126 mg/Kg, 685.877 mg/Kg for treatment 40 ppm, 80 ppm, and 120 ppm respectively) than the levels of chromium in water lettuce (1584.264 mg/Kg, 1660 mg/Kg, 1413 mg/Kg for treatment 40 ppm, 80 ppm, and 120 ppm respectively). Physiological parameter, i.e., chlorophyll and proline levels in water hyacinth and water lettuce from all concentration treatment did not differ significantly (P> 0.05). The activity of the catalase enzyme in water hyacinth and water lettuce decreased with increasing chromium levels. The highest catalase enzyme activity was observed in control treatment of water lettuce (1.61 unit/mg) and 40 ppm treatment of water hyacinth (1.006 unit/mg). The highest biomass dry weight of both plants was found in plants with control treatment (15.38 gr and 8.48 gr for water hyacinth and water lettuce respectively). Therefore, we concluded that water lettuce is better for trivalent chromium removal than water hyacinth.

Abstract

We investigated the effect of paraquat dichloride herbicide application on diversity and abundance of soil arthropods in a corn field. In addition to control (0 mL/L), four concentrations of paraquat dichloride were applied i.e. 3.33 mL / L, 4 mL / L, 4.66 mL / L and  5.33 mL / L. Sampling was carried out four times, namely at T0 (before tillage), T1 (after tillage), T2 (after spraying herbicides), and T3 (before harvesting) using a pitfall trap method. Soil arthropod samples were identified to the family level. The total number of individuals was then analyzed to obtain species richness, species dominance index, species diversity index and similarity index of Sorensen. The result showed that paraquat dichloride did not give any significant effect (p>0.05) on the number of individuals, species richness, species dominance index, diversity index and Sorensen similarity index of soil arthropods. The composition of soil arthropods in the control and in the treatment with the highest concentration shows a high level of similarity.
