Abstract

Along with the development of the tourism in Bali, one of the phenomena occurs was that the land conversion to the non-agricultural land, causing the canal irrigation was not able to function again. In addition, water demand will be increased not only for irrigation, but also for other sectors out of irrigation. This condition can interfere the performance of the subak system. One strategy to improve subak system is to develop agroecotourism based on subak system. Analysis of physical performance subak system done using fuzzy logic approach to quantify the condition of vagueness. Because of the problems associated with subak irrigation systemperformance are often vague and can not be classified with certainty. The results of this study are (i) the values of subak irrigation system performance indicators, the condition and thefunction of subak irrigation facilities, the condition and the function of subak facilities, and the agroecotourism facilities; (ii) find out the physical performance of subak irrigation systems in Bali with agroecotourism oriented. The stages of this research were collecting and analyting the data include: (i) RWS (Relative Water Supply), (ii) RIS (Relative Irrigation Supply),(iii) Ia (Index Area), (iv) analysis of the condition and function of subak irrigation networks, (v) the condition and the function of subak facilities, (vi) the agroecotourism facilities, and (vii) physical performance of subak system using fuzzy logic approach. The utilization rate of water on Subak Anggabaya and Subak Lodtunduh in one year was good. Subak Anggabayaand Subak Lodtunduh have sufficient irrigation water supply with RIS values in one year > 1. Based on Area Index (Ia), it could be seen that the irrigated area in Subak Anggabaya andSubak Lodtunduh in accordance with the plan. The physical performance of Anggabaya subak system and Lodtunduh Subak system was in the middle criteria. The simulation results that development of agroecotourism on subak system could improve the physical performance of subak system.

Abstract

This study was conducted in Pogung-Code sub watershed and Pulo-Opak sub watershed from 1993 to 2002. A deterministic model developed by Haan (1972) was used to determine the amount of water yield from watersheds. The model consists offour parameters, namely: (0 maximum rate of seepage from the soil water zone in mm per day (S), (ii) maximum soil moisture less readily available for evapotranspiration in mm (C), (iii)fraction ofseepage from the soil water zone that becomes runoff(F), and (iv) maximum infiltration rate in mm per hour (f.).The inputs required by the model were the daily rainfall and the estimated potential evapotranspiration which was computed using Penman method. Streamflow records for 10 years of Pogung-Code sub watershed (2,801.77 ha) and Pulo-Opak sub watershed (4,856.37 ha) were used to test the validity of the model. The parameters obtained for Pogung-Code sub watershed were: S = 0.70 mm per day, C = 112.32 mm, F = 0.63, and- 5.38 mm per hour, meanwhile for Pulo-Opak sub watershed were: S = 2.33 mm per day, C = 86.72 mm, F --- 0.26 and f = 5.68 mm per hour.The final test of the adequacy of the model lay in a comparison of observed and simulated runoff The comparison showed that the observed and simulated runoff values are not significantly different. This was based on the results obtained from statistical measures to test the model. The model did a better simulation in the smaller watershed (Pogung-Code sub watershed) than in the larger one (Pulo-Opak sub watershed).

Abstract

Subak irrigation system beside as an appropriate technological system, but as acultural system as well. This fenomenon indicate that basically subak irrigationsystem is a technological system that has been developed as a part of cultural society.Because subak system is viewed as a technological system, so this system has anability to be transformed. Meanwhile, limitation of the ability of subak irrigationsystem to overcome the extreem conditions, basically can be solved through theharmony and togetherness, based on the Tri Hita Karana (THK) principles as a basicof subak system. Futhermore, through inverse technique, it can be seen the ability ofsubak system, that can be transformed. And then, through Fuzzy Set Theory, it can beseen the dominance or ranks of the all elements of subak system, which are also as aconsideration on the transformation process.

Abstract

Recession curve is a spesific part of stream hygrograph after it reachs peak flow and it represents the withdrawal of groundwater from storage. Daily recession constant of surface runoff, interflow, and baseflow have been derived for 15 segments on Goseng subwatershed with area approximately 596 ha.Semi logarithmic plot is recession analysis method which plotting stream discharge in y-ordinate and time in x-coordinate in semi logarithmic scale. The start of time recession is denoted by a straight line in the graphic. This method was used for separating a hydrograph into linear components of surface runoff, interflow, and baseflow. The results of the research shows that recession segment from daily hydrographhas short time and does not have all three stream components. A short segment can only be divided into two flow components. Separation pattern for water catchment area are baseflow-interflow, baseflow-surfacerunoff, and interflow-surface runoff. Recession constant value differ from year to year but the differences do not have great influence in determining the average value of recession constant.Keywords : surface runoff, interflow, base flow, recession constant, semi logarithmic plotDiterima: 26 Agustus 2008; Disetujui: 3 Pebruari 2009

Abstract

ABSTRACTDeclining productivity of plantation forest due to low soil fertility. This condition has forced managers to make efforts in manipulating the tree growing environment. One such effort is by introducing cover crops species from legumes (LCC), to control surface runoff, soil erosion and input nutrient into the soil. The research aims to determine the effectiveness of LCC in controlling total runoff and sedimentation in Eucalyptus pellita plantations, through dynamic model simulation. The dynamic model of STELLA version 9.0.2 was used to study water and nutrient cycles, focused on the application of LCC to reduce total runoff and sedimentation. The results showed that LCC could drop the total runoff of average 35% in the 1 - 2 years old. In the 1styear it decreased from 1,530 mm to 994 mm, while in the 2ndyear it decreased from 1,240 mm to 806 mm. The declining also occurred in the sediment content, in the 1st year it decreased from 12.20 tonnes/ha to 7.93 tonnes/ha, and the 2nd year it decreased from 6.63 tonnes/ha to 4.36 tonnes/ha. These research findings can be used by the environmental manager to minimize potential land degradation, especially during the post-harvest until the young plantations (0-2 years old) phases.Key words: plantation forest; E. pellita; dinamic model; legume cover crops; erosion; runoff ABSTRAKPenurunan produktivitas hutan tanaman akibat rendahnya tingkat kesuburan tanah memaksa pengelola melakukan berbagai upaya manipulasi lingkungan pertumbuhan.

Abstract

The Industrial Revolution 4.0 has transformed education, particularly in technical drawing, requiring students to develop ICT literacy, social skills, and active engagement. However, many students face challenges in mastering ICT tools and collaborative skills, impacting their academic performance. This study uses a quantitative approach with an ex post facto design to analyze the relationships between student engagement, ICT literacy, social skills, and student performance. A Likert-scale questionnaire was distributed to 91 technical drawing students at Yogyakarta State University, and the data were analyzed using the SEM-PLS method. The results show that student engagement is the most influential factor in improving academic performance, followed by ICT literacy and social skills. Active student engagement enhances ICT literacy, which supports collaboration and boosts learning outcomes. Social skills, while less directly impactful, facilitate teamwork, which is crucial for technical drawing projects. This study emphasizes the need for integrated learning approaches combining engagement strategies, ICT literacy development, and social skill enhancement through digital tools and collaborative projects. These findings contribute to curriculum development, ensuring students are equipped to meet Industry 4.0 demands.
