Debit Puncak Harian Tahunan Metode HSS Nakayasu dan Debit Terukur di DAS Muke Kabupaten TTSS SERVICES-CURVE NUMBER DAN DEBIT TERUKUR DI DAERAH ALIRAN SUNGAI MUKE KABUPATEN TIMOR TENGAH SELATAN

The Muke River is prone to flooding. flooding is caused by conversion in land use due to the migrating plantation system. In the Muke river, it is necessary to analyze the discharge estimation to determine the potential of water in the Muke river. In this study, the authors performed peak discharge calculation using measured calculation model and calculate. Measured calculations using discharge’s curve and calculated by using hydrographic method of synthetic unit namely Nakayasu. The results of the analysis for the calculation of discharge on the Muke river using the discharge curve obtained that the peak discharge occurred in 2012 with Qmax = 99.41 m3/s and the smallest discharge occurred in 2010 with Qmin = 13.19 m3/s, the results of the analysis for the calculation of discharge on the Muke river using the Nakayasu method obtained peak discharge occurred in 2010 with Qmax= 184.74 m3/s and the smallest discharge occurred in 2014 with Qmin = 94.33 m3/s.

Monitoring System of Hydroponic Using Solar Energy

This project aims to develop a solar powered hydroponic monitoring system. Hydroponic system is a plantation system that uses water as the medium instead of soil. The solar energy acts as the main source and a supply for the Arduino Uno, a microcontroller to control all the sensors, collecting the data and display the data to users. The sensors used were DS18B20 temperature sensor, propylene float water level sensor and pH sensor. These sensors will monitor those elements and helping the users in hydroponics system. An Arduino Ide software was used to develop a coding for the monitoring system. The value of temperature, water level and pH has been measured and collected to be analyzed. For conclusion, this project is successful in that the data collected satisfied the objective and from the result, it shows the effectiveness of solar powered hydroponic monitoring system.

Carbon sequestration potential under tea based cropping system

Aim: To study the carbon sequestration process in tea based plantation system and to identify more potential carbon sequestration system amongst the tea based cropping system by studying carbon storage in different components of the plantation system. Methodology: The experiment was carried out in the Experimental Garden for Plantation Crops of Assam Agricultural University, Jorhat, Assam. Treatments were made in an on going, long term shade experiment on mature tea bushes, adapted to three levels of shades viz. tea as monoculture; Tea based cropping system with Areca palm and Tea with Albizzia odoratissima. Results: Among different tea plantations, tea-albizzia recorded superior performance, followed by tea-areca palm plantation in respect to biomass accumulation and carbon sequestration. Similarly, higher carbon stock was found in tea-albizzia plantations along with other physiological and edaphic parameters related to carbon sequestration attributed to an increase in carbon stock. Interpretation: Tea-albizzia plantation system has maximum potential for carbon offsetting from the atmosphere as well as carbon storage both above and below ground in the plantation ecosystem which might be helpful for future carbon management and economy as a whole.

Analysis of Fire Catchers in Sago Palm Smallholding Plantations on Peatland in Tebing Tinggi Timur, Kepulauan Meranti District, Riau Province

Fire on peatlands takes place not only in areas where preparation for cultivation is in progress, but also in areas that have been cultivated, such as for sago palm growing. One of the important factors that influence the vulnerability of cultivated peatlands to fire is the availability and amount of biomass fuel that easily catches fire, such as ferns, grasses, and broadleaved shrubs in their living as well as dead (litter) stages. The present study concerns the vulnerability of peatland utilized for sago growing by smallholders, focused in Tebing Tinggi Timur, Kepulauan Meranti District, Riau Province. The objectives of this study were to analyze the composition and assess the biomass of fire catchers in the sago palm plantation. Data collection was conducted in three locations in Kepau Baru Village. In each location, a 1000 m-long transect line was drawn and 10 sampling plots of 2 m x 2 m were established along the line with 100 m intervals. Results showed that total biomass of fire catchers in this growing system was averaged at 24681 kg/ha, in which the dead plant fraction was predominating (average at 17478 kg/ha or 70.81%) over the living plant fraction (in average 7203 kg/ha or 29.19%). The latter consisted of ferns that averaged at 2.191 kg/ha or 30.42%, grasses (20 kg/ha or 0.28%), non-woody broadleaved shrubs (581 kg/ha or 8.07%), and woody broadleaved shrubs (4411 kg/ha or 61.24%). The amount of fire catchers in relatively large quantities in this plantation system could magnify fire risk during drier months, especially during El-nino years. Keywords: biomass, fire risk, grasses, non-woody broadleaved shrubs, woody broadleaved shrubs

Extensions after Man: Race, Counter/insurgency and the Futures of Media Theory

This article returns to the geopolitical scene and racial logics that provide the underacknowledged conditions of Marshall McLuhan’s Understanding Media and, specifically, its well-known proposition that media should be understood foremost as ‘outerings’ or ‘extensions of man’. Attending to the structuring inheritances of racial slavery and the plantation system in this founding statement of mid-twentieth-century media theory, as well as its debt to the literary and intellectual movement of the Southern Agrarians, I consider how the racializing figure of ‘Man’ conserved by the nascent field of media studies was contemporaneously brought to crisis by black (and) anticolonial freedom struggles. Arguing for the need to reread the career of western media theory through its political vocation in attempting to manage this crisis, the article concludes by turning briefly to a revisionary account of media and exteriority also circulated in 1964: the revolutionary intellectual James Boggs’s ‘The Negro and Cybernation’. Boggs’s writings, which situate emergent forms of computing and cybernation within a longer materialist genealogy of race, capitalism and technology, offer both a proleptic critique of the early disciplinary formation of media theory and a divergent set of coordinates for approaching media technology on the terrain of black political struggle.
