Abstract

The main target of development is not development itself, but rather to maintain and preserve the ecology, and the criterion is the quality of life achieved by guaranteeing the life of the ecological, socio- cultural, economic, proportionately. Both sustained human and ecological sustainability are the two alternatives can be chosen to be applied by individual countries, including Indonesia.Paradigm of sustainable development is a critique of the development of economic growth. In addition, sustainable development is also a normative theory that conveys the development practices are  long-term dimension and intergenerational. This theory is a way out of the failure of growth  development paradigm. Three main principles of sustainable development is the principle of democracy, justice and sustainability. These three principles must be practiced together in a single unit to achieve development that meets present needs without compromising the right of meeting the needs of future generations.Nevertheless, the theory of sustainable development also has major weakness, namely: first, there is no clear and measurable point of the period  that becomes the targets  of sustainable development, only a commitment that is difficult to measure when the achievement can be reached. Second, the assumption is based on the anthropocentric view that sees nature only as a tool for the fulfillment of material needs of man. Third, assuming as if humans have the ability to know the limits of nature and able to exploit natural resources within the limits of carrying capacity of nature. Fourth, the paradigm of sustainable development rests on the ideology of materialism that is not critically examined but  is accepted just as true.

Abstract

Literature in essence is a medium for authors to communicate withtheir environment. Poetry is one of the popular literary genre becausein addition to giving inner pleasure, smoothing mind, enhances faith,is also often raised life expectancy to a better direction. In this context,the poem can be a guide and communication tool to do somethingmore perfect. K.H.A. Mustafa Bisri (Bisri) is one of the famous poetwith a social expression. Through his poems, Bisri not only to protestagainst the injustice that has been going on since long in the country,it is said, ‘embrace’ and ‘run’ this democracy, but rather a point toteach about communication and democratic practices philosopher.Thus, the poems can be juxtaposed with the idea of Jϋrgen Habermas(Habermas) in practice ‘communication democratic society’.Thisstudy analyzes the notion of similarity between two characters, each ofwhich as a poet (Bisri) and on the other as a philosopher (Habermas).The theory used in this discussion is the notion of semiotic, theory ofMichael Riffaterre, especially who said that the meaning of a poemcan be traced in the displacing of meaning which means there is ahidden meaning behind the word is written in verses of poetry. Withthe theory that the four poems of Bisri: (1) “Wekwekwek” (picturea communication practice), (2) “The Big Man, The Little Man”(the irony of a communication practice), (3) “You’re What I NeedWhat neither” (a protest against the practice of communication),and (4) “Prophet Sulaiman smiling “(the practice of truth-worthycommunication-sample by a democratic society). Readings are thenconfronted with the idea of Habermas.The result is that both havethe same idea. If Habermas formulate it into a theory he called a “discourse”, Bisri voice them in the form of verses of poetry. If Habermassays “this should be done”, exemplifies Bisri to do.In reality, humans according Hebermas is in objectivization, people according Bisri is just parroting; language used by Habermas to suppress, accordingBisri language used to control the people; according to Habermas’svalidity claims require explanations and reasons, according to People Bisri, questioned the validity of the ruler; ideal communication byHabermas is intersubjective communication,  while according to Bisri rulers and people must reach a consensus.

Abstract

The high number of tin mining in the Bangka Belitung Islands leaves a number of problems such as unused land after tin mining. Whereas on the other side, the post tin mining areas can be used as a source of water reserves although additional treatment is needed because it is feared contain heavy metals. Calcium oxide is a compound that can be used to coagulate dispersed pollutants in water so that it can be used to improve the quality of water stored in the post tin mining area. One of the most abundant sources of calcium in the Bangka Belitung Islands comes from wasted cockle shell. Through a heating process at temperatures of about 700°C calcium carbonate in the wasted cockle shell will begin to decompose into calcium oxide. Based on the results obtained have known that the longer the heating process then the decomposition process of calcium carbonate more and more occur.  Keywords: Rietveld, calcium crystal, heat treatment.

Abstract

Kursi roda adalah alat bantu yang digunakan oleh orang yang mengalami kesulitan berjalan oleh penyakit, cedera, maupun cacat. Beberapa peneliti telah mempergunakan teknologi yang mula-mula dikembangkan untuk mobile robot untuk menciptakan smart wheelchair (kursi roda cerdas), yang mengurangi kebutuhan fisik, keteramatan, dan keterampilan yang diperlukan untuk mengoperasikan kursi roda standar.Kursi roda cerdas didisain untuk menyediakan kemudahan bagi pemakainya. Menurut data Susenas (Survey Sosial Ekonomi Nasional) tahun 2000, difabel di Indonesia mencapai 1,46 juta penduduk yaitu sekitar 0,74% dari total penduduk Indonesia (197 juta jiwa) pada tahun tersebut. Persentase difabel di daerah pedesaan sebesar 0,83%. Lebih tinggi dibanding dengan persentase di daerah perkotaan sebanyak 0,63%. Sedangkan menurut Badan Kesehatan Dunia (WHO) belakangan memprediksikan bahwa satu dari 10 orang Indonesia adalah difabel. dibandingkan hasil Quick survey WHO tahun 1979, yang para peneliti menyimpulkan bahwa difabel di Indonesia mencapai 3,11 Diharapkan bahwa karya teknologi kursi roda elektrik ini dapat mengantisipasi meningkatnya jumlah pasien lanjut usia danhandicap. Para peneliti bidang robotika mengklasifikasikan kebidang mobile robot, diman arobot kursi roda merupakan robot medis yang berfungsi sebagai alat bantu untuk penderita lumpuh dan lanjutusia (lansia). peneliti telah menguji coba beberapa desain kursi roda dari tahun 1967 sampai 1996 danjuga mempelopori pengembangan dan penggunaan kursi roda yang dapat digunakan untuk menaiki/menuruni tangga. Stair-Climbing power wheelchair atau kursi roda yang dapat menaiki/menuruni tangga. Para peneliti di NIRE telah membuat kursi roda dengan sistem kontrol komputer yang dapat dikendalikan melalui komputer dan memiliki sistem autopilot serta sensor yang dilengkapi giroskop untuk memonitor keadaan permukaan jalan. Penelitian lainnya mengenai kursi roda yang dilakukan oleh Jauhar Wayunindho, yaitu menciptakan kursi roda listrik yang dikemudikan dengan gerakan mata, sehingga orang yang lumpuh total mudah untuk menggunakannya. Kursi roda ini menjadikan posisi retina mata pemakai sebagai pengganti joystik untuk mengendalikan kecepatan dan arah kursi roda itu. Namun penelitian tentang rancang bangun kursi roda untuk yang dapat berjalan diatas tangga masih sangat sedikit di Indonesia, sehingga penulis memilih judul yang bertemakan kursi roda sebagai mobile robot. dibandingkan dengan robot manipulator berkaki serta tersedianya kursi roda yang akan dijadikan sebagai alat eksperiment
