Abstract

Climate change is an unavoidable thing due to global warming which has a wide impact on various aspect of life. Changes of rainfall patterns, increas of the frequency of extreme climate and an increase in air and sea levels are serious impacts of climate change that will affect the agricultural sector. For Indonesia, the threat of climate change will have a serious impact on achieving sustainable developmenttargets. For the Bali Province, climate change causes disruption of water supply for various sectors, including agriculture sector. This is indicated by the decrease of land area that was very suitable for paddy rice untill 20% as long in the period 1990-2009. Due to changes in rainfall by climate change, the current cropping pattern of rice must also be adjusted. In an effort to address climate change, can be done through the plant of low emission varieties, use of organic fertilizers, adjusting cultivation techniques through water and land management and socializing the importance of agricultural insurance for  educing farmers' risk due to climate change.

Abstract

Dynamics of Pest Population and Main Diseases of Sweet Corn Plants (Zeamays saccharata Sturt) at Wetland with Conventional Cultivation Systemand Their Effect on Yields in Denpasar-Bali. The study was conducted usingsurvey techniques of pests and diseases in paddy fields belonging to farmers in Denpasar-Bali, which consists of three fields. The three areas were Sidakarya, Renon and Kesiman.Plant samples in each land were taken using the sample plot diagonal method, with the areaof diagonal plot in each land was 3 m x 3 m. Plot observations on each of the specified areaof plant samples was done randomly (lottery) as much as 25% of the total number of plantsper-plot, then observation was done for population growth of pests and diseases, temperature,humidity and crop yield. The observations was started from 1week old plants after planting(MST) to 1 week before harvesting, with intervals of 1 week. Recording the population ofpests and diseases from week to week, the temperature condition and humidity in each areaand the condition of the field ( the existing other plants, mulching). Recorded informationabout conventional cultivation systems applied by each farmer were be explored throughinterview techniques. The data were then analyzed using correlation and regression and weredescriptively explained. The results showed that there were four main types of pests (locusts,seed flies, armyworm and caterpillars cob) and three kinds of major diseases (blight, rust anddowny mildew) associated with sweet corn. The results also showed that there was nosignificant between the correlation dynamics of pest population and diseases withtemperature and humidity. As for the commercial harvest, significant effect was shown by thediseases that had an impact on the decrease in yield in quantity especially downy mildew andpest impact on the quality of yields, especially caterpillar cob.

Abstract

The Socio-economic and Environmental Impacts of the Robusta Coffee Processedby the Tugu Sari Village-Owned Enterprise ?BUMDes?, Pajahan Village,Pupuan District, Tabanan RegencyThe Tugu Sari Village-Owned Enterprise ?Badan Usaha Milik Desa (BUMDes)? is aRobusta coffee processing enterprise run by the village. It was established to support theVillage?s Original Income ?Pendapatan Asli Daerah (PAD)?, improve the local people?sprosperity, serve the local people, improve the management of the village?s assets, andmaximize and sustain the potential which the village, as the one where Robusta coffee isproduced, has. This current study was intended to identify the impact of the existence ofthe Tugu Sari BUMDes, Pajahan Village, based on the sustainable development system.Three impacts were explored in the current study. They are the social, economic andenvironmental impacts. The social and environmental impacts on the existence of theBUMDes were measured through the local people?s perception, and the economicimpact was measured based on the score obtained using the Keynesian economicimpact. The result of the study shows that the local people?s perception of the socialimpact of the BUMDes was good. The economic impact was that the existence of theBUMDes could contribute to the local people?s economy based on the score obtainedthrough the Keynesian multiplier effect, namely 1.35. The local people?s perception wasnot good environmentally, as the noise produced by the coffee processing machinedisturbed the learning process at Elementary School 2 Pajahan. Therefore, it issuggested that the coffee processing machine should be relocated, so it would notdisturb the learning process at Elementary School 2 Pajahan.

Abstract

Determination of Groundwater Prices for Sustainable Irrigation in JembranaRegency Subak Babakan Yehkuning is relatively new in obtaining Groundwater IrrigationNetwork, with the code YKN-127 in 2014. This study aims to determine the costcomponents and water prices that reflect the value of water use in a sustainablemanner. The method used in this research is quantitative calculation. The total waterdischarge from YKN-127 for three planting seasons in September 2015 until August2016 consecutively was 83,647.01 m3. This amount was derived from the total life ofthe pump for 2,733 hours, with a discharge 8.5 liters/second. The commoditiescultivated in three planting seasons were rice for two times and secondary crop (cornand soybean). Since the availability of ground water has a limited amount, it isimportant to note that the amount of water use should be less than the availabilities.The concept of sustainable value in the use of water is consisted of the total cost ofsupply, opportunity costs, and externalities costs. The results showed that the waterprice reflecting the sustainable water use value for irrigation at YKN-127 was Rp3,933.91/m3, which consisted of a full supply cost 65.9% (Rp 2,592.42/m3), anopportunity cost 27.9% (Rp 1,099.43/m3), and depletion premium 6.2% (Rp242.06/m3). This result is almost three times the operational and maintenance coststhat farmers usually pay for Rp 1,633.99/m3. This price describes the value that mustbe paid as an effort to maintain the development of irrigated agriculture sector andground water resources in order to remain sustainable in Jembrana, Bali Province.

Abstract

Pod rot disease in cacao (Theobroma cacao) caused by Phytophthora palmivora has been loss until 90%. The major economic loss is from infection of the pod. Pods can be infected at any age, but most significant economic loss arises from infection during the two months prior to ripening. Pod infected at this stage can be a total loss because the fungus can easily pass from the pod husk to the seed-coat of the bean in a cacao still be convergent only at usage of synthetic pesticide. Therefore need to be searched other alternative to control the disease, namely by exploiting antagonist microbe. Research has been done in Laboratory of Microbiology and Microbial Pesticide, Department of Agroecotechnology, Faculty of Agriculture, Udayana University, Jl. PB. Sudirman Denpasar, from April until October 2007. There are three research phases done like : 1) insulation pathogen cause of disease, 2) antagonist microbe inhibitory activity test to growth of pathogen in vitro, and 3) inhibitory activity test free cell antagonist microbe to growth of pathogen in vitro. Result of research shows, found two species pathogen cause of pod rot disease of cacao namely Phytophthora sp. (A) and Phytophthora sp. (B). Based on result of examination out of four antagonist microbes tested like Trichoderma sp.; Saccharomyces sp.; Pseudomonas fluorescens and Bacillus sp., that is most effective in depressing pathogen is Trichoderma sp. with inhibitory activity equal to 83,98% to Phytophthora sp. (A) and 82,18% to Phytophthora sp. (B) at PDA media. Secondary metabolite released by fourth of antagonist microbe depress both pathogen cause of pod rot disease of cacao at PDA media.

Abstract

Pod rot disease in Cacao (Theobroma cacao) caused by Phytophthora palmivora has been known to cause serious damage at cacao-growing area in the world. The disease can cause crop loss until 90%. Hitherto cacao farmer controls disease only on usage of synthetic pesticide. Therefore important is performed a operation research of disease with other alternative, like usage of leaf extract Piper betle and clove flowers (Eugenia caryophillata), as botanical pesticide. Research has been conducted in Pulukan village, Sub-Province Jembrana in January until April 2006, to study botanical pesticide effectivity (plant extract) to control pod rot disease. Research applies completely randomized block design, with four treatments and six replications, causing is required 24 experiment units. Every re-attempt unit thrice and ten tree pears observed as sample. Disease percentage is observed every one week once in each treatment. Results of the experiment indicated that leaf extract of P. betle and clove flowers effective controls pod rot disease (alone or in combination). The extract mixture P. betle and clove flower (combination) can suppress disease until 64,57 %, clove flowers extract (alone) 33,33% and synthetic pesticide (Dithane M45) equal to 60,40%. Result of this depicts treatment tested is usable to reduce pathogen pod rot disease of cacao.

Abstract

Gringsing is one of the traditional fabrics that are characteristic of the Tenganan Pegringsingan Village. Gringsing is quite unique because in its manufacture it uses double-ikat techniques, where this technique can only be found in three places in the world, such as Japan, India, and Tenganan Pegringsingan Village. In 2016 Gringsing was certified by the Ministry of Law and Human Rights of the Republic of Indonesia as a Geographical Indication. This study aims to building a deep learning model to recognize Gringsing motifs and know the performance of the model, so that people can more easily recognize Gringsing motives without having special abilities. The model was built using the Convolutional Neural Network (CNN) method with the AlexNet architectural model. Tests are conducted to determine the performance of the model such as training time, accuracy, precision, recall, and f-measure value. Based on the test results the model built was able to complete 100 epoch training with a time of 19,33 hours, and has an accuracy value of 76%, 74.1% of precision, 72.3% of recall, and 0.73 of F-measure.

Abstract

DIVERSITY OF SUPRESSIVE LAND MICROFLORA IN CONTROL OF PALLDER DISEASE IN CUBES PLANT (BRASSICA OLERACEA L.)Cabbage (Brassica oleracea L.) was a vegetable crops cultivated in the highlands to meet the needs of the community vegetable. The main obstacle was the cultivation of cabbage root disease outbreak mace (clubroot), which until now have not found an effective control techniques. Clubroot disease caused by organisms that resemble fungi: Plasmodiophora brassicae Wor. which was the soil inhibitant and soil borne pathogen. Therefore, there must be a way to control environmentally friendly by using suppressive soil, find microbes antagonists related to the cabbage plant habitat in the soil. The results showed that the index of diversity both on suppressive and conducive soil of 1.2304 and 1.2811 respectively, and the index of dominance on the suppressive and conducive soil were 0.6677 and 0.6838.  Prevalence micoflora of the suppressive soil amounted to 44.22 % and 43.06 % conducive soil all dominated by Fusarium spp. Microbial antagonist as a potential control of P. brassicae was Trichoderma sp. Based on the analysis in the suppressive soil as much as 171 x 103 cfu /g soil, higher than on the conducive soil to 90 x 103 cfu /g soil.

Abstract

Every one of us uses carbon dioxide emitting energy source in our daily activities. The purposes of this research were to obtain information on the level of household activities of carbon footprint and to obtain information on the most influential factor of household activities in Denpasar City. The research method employed was the descriptive quantitative. The analysis of the first purpose was obtained by the multiplication of emission factor and the use of LPG and electrical capacity. The analysis of the second purpose was obtained by implementing the analysis of doubled linier regression supported by employing SPSS version 16.00 program for Windows. The research result showed that the average of the total carbon footprint was as big as 138,037.02 g of carbon/month. Based on that average, the total of carbon footprint in Denpasar city with as many as 15,908 households was 2,195.89 ton CO2e/month. The statistic analysis test showed the factors that influenced the carbon footprint were the amount of household members, the amount of household equipments which needed LPG to operate, the amount of household equipments which needed electricity to operate and the duration of using electric equipments whose R2 power was as big as 90%. The duration of using electric equipments had the highest correlation with the value of 62.70 %. It is suggested that households should use energy saving equipments such as LED products; the government should consistently promote carbon saving movements; and to future research to calculate carbon footprint by using DNPI carbon calculator, or by using software LEAP.
