Abstract

ABSTRACTThe study aimed to determine the extent of the physiological status of Balinese cattle (Bossondaicus) females maintained on peatlands including environmental temperature, respiratoryfrequency, body temperature, pulse rate, and rumination which is important to know the healthstatus of female Balinese cattle. This study used 10 female Balinese cows with an average bodyweight of 300 kg and age ranged from> 24-36 months, non-pregnant status. Physiological statusmeasurements were carried out in the morning, afternoon and evening. This study uses descriptivemethods and direct observation with data processing in analysis and tabulation. Research has beencarried out at the Joint Work Group of Taruna Taruna, Tanjung Taruna Village, Jabiren RayaDistrict, Pulang Pisau Regency. The research began on January 1, 2018 to February 2, 2018. Theresults showed that the average cage temperature in the morning was 28.0 0C and humidity was79.4%. While during the day the temperature of the cage is 33.8 oC and humidity is 58.7% and inthe afternoon the temperature of the cage is 30.0 0C and 73.6%. The average respiration frequencyof female Balinese cattle in the morning is 21.1 times per minute, while during the day is 24.3times per minute and in the afternoon is 24.5 times per minute. The average body temperature offemale Balinese cattle in the morning is 37.4 0C, during the day is 38.1 0C and in the afternoon is38.2 0C. The average pulse rate of Bali cattle, in the morning is 60.3 times per minute, during theday is 65.2 times per minute while in the afternoon is 63.7 times per minute. The averagerumination in the morning was 55.2 times chewing in 31.9 seconds, during the day the averagerumination was 55.3 times chewed in 31.7 seconds while on the afternoon the average ruminationwas 55, 3 times chew in 31.8 seconds. The physiological status of Bali cattle is respiratoryfrequency, body temperature, and pulse are in normal conditions. The condition of the ambienttemperature exceeds the normal threshold and the rumination in cattle is very high this conditiondoes not cause health problemsKeywords: Bali Cattle, Micro Climate, Physiological Response

Abstract

ABSTRACTThe high availability of organic compounds in peatlands is stored capital and can be converted intoelements by soil microbe. The high organic content causes nutrients in the soil cannot be directlyutilized by plants. Phosphate solubilizing bacteriaare soil bacteria that capableofsolubilizingphosphate, turns it into an available form in the soil. The aims of this research are todiscover the existence of a phosphate solubilizing bacteriagenus and obtain potential pure isolatesfrom Bereng Bengkel peatland, Central Kalimantan. Bacteria isolation usingselective mediaPikovskaya with pour plate method. The isolation results are five phosphate solvent bacterialisolates (BPF1, BPF2, BPF3, BPF4, BPF5) which form hallozone. Based on the characterizationresults refering to the Bergey's Manual of Determinative of Microorganism through macroscopicobservation, microscopic observation and physiological testing. BPF1 and BPF5 isolates were thegenus Rhodococcusgenus, BPF2 isolates were theRhizobiumgenus, BPF3 isolates were theMicorococcusgenus, BPF4 isolates were the SerratiagenusKeywords: Phosphate solubilizing bacteria, peatland, soil bacteria

Abstract

ABSTRACTThe lack of field measurements, which collected in long period and significantly spatial effect onthe environments can obstruct scientific understanding the effect of environmental condition on theecosystems. Application wireless sensor network (WSN) is useful to address the situation throughlow cost wireless measurement sensors and minimize disruption to the location/conditions to bemonitored. The comprehension of composition transformation, structure, the environmentecosystems dynamic, and how is the transformation of all can be affecting the human life, indeedthis challenge are need detail analysis of all environment ecosystem elements. This study alsoreview the uses of smart devices wireless sensor networks (WSN), and observe the underlyingtechnology in hopes could be giving solve or determine the condition of environment andecosystems affected by human activity. The results of this study showed that the land use cover isinfluence on the environment conditions.Keywords: Wireless sensor networks (WSN), ecosystems, and environment

Abstract

The burned peat in the farmland, Kalampangan Village have changed quite dramatically, such the water level is inundated during the rainy season and very dry during the drought season. Such conditions could be affecting the process of decomposition and chemical properties of peat and peat water associated with the availability of nutrients, especially nitrogen. This study aims to determine how the effect of water levels on the status of N in the burned ombrogenic peat in the Kalampangan Village. This research was uses a method of incubation as long as 40 days with the hanging column with the differences of water levels are 0, -10, -20, -30, 10, 20, and 30 cm. Parameter chemical properties of peat and peat, namely pH, total N, organic C, ammonium, ammonia, nitrite and nitrate. Analysis of data of the chemical properties of peat and peat water was done by using ANOVA level of 5% and 1%, then also regression and correlation analysis. The results have showed that there was no significant effect on the chemical properties of water and peat due to the changes in water level. Incubated peats have a very acidic pH with a high positive correlation at drying and a low positive correlation at inundation, while the peat water was indicates a perfect positive correlation at drying and high negative correlation at inundation. Peat showed a high total N with a low positive correlation at drying and a perfect negative correlation at inundation, while the peat water was indicates a perfect positive correlation at drying and a high negative correlation at inundation. Ammonification and nitrification processes were occurring that indicated by the accumulation of NH4 + and NO3 in peat and peat NO3 dissolved in water, where were the results of the regression analysis contained pattern polynomial equations and linear patterns. The equation can be used to predict the concentrations of all three parameters due to the changes in peat water level in Central Kalimantan

Abstract

Different sectors of industry have a need for DC motors due to their benefits, such as substantial torque, absence of reactive power loss, no disruption to power supply, and precise control. Automation in control plays a crucial role in advancing science and technology. An effective control system must fulfill specified criteria, encompassing performance indices associated with accuracy, stability, and rapid response. An optimal control system is one fashioned through the optimization of performance indices, considered optimal when parameter values are chosen to maximize or minimize the selected performance index. In the context of DC motors. In the context of speed regulation using the Linear Quadratic Regulator optimal control technique, the optimization of performance indices involves configuring the Q matrix value. This, in turn, results in the generation of the K feedback amplifier matrix and the optimal L tracking matrix for the DC motor. The process is repeated for speed regulation in the DC motor using the Linear Quadratic Regulator optimal control technique, where performance index optimization is achieved by adjusting the Q matrix value, leading to the derivation of the K feedback amplifier matrix and the optimal L tracking matrix.
