Abstrak: Thc exotic of social culture and thc natural beach of Bali are the two important aspects which attract tourists to come to Bali. This bring a positive economic impact to the local community and to the national economy, but it also raises the question on the negative impact to the environmen. The recent problem occurs in Kuta beach resort is the development of uncontrollable aglomeration process. Kuta has been transformed from what once a beautiful natural environment into a harsh and polluted urban environment which could result in the decreases of the tourist visit. The objectives of the study are: (a) to identify the impact of tourism development on the environment and the social and economical aspects in particular, and (b) to analyze the process of change ahd development of ecotourism of Kuta beach resort. The study uses the 1995 farm survey data, conducted in three Kelurahan of two Kecamatan in Kuta beach zone, with a total sample of 460 fann households. These kinds of data collected were maidy- on land holding and factors which determining it. Besides, the time series secondary data, consist of data such as; Gross Domestic Product (GDP) and employment of Bali, investment on the directly productive activities @PA) on the tourism industry and the social overhead of capital (SOC), and the pattem of land use change. The secondary data were used also to elaborating the physical, biological and social cultural environment aspects.

Abstrak: Potential development of Batam City as a Coastal Development Zone which undergoes very fast growth may act as a primary mover of the national economy. However, based on its potential, Batam City faces a dilemmatic position, between its strategic potential and bright prospects or constraints and tendencies threatening the sustainable capacity of the area. Hence, an alternative development strategy that fulfills the need of current and future generation, called the sustainable development, is required. The purpose of this research were. 1). To determine constraints in political economy aspects consisting of ecological conditions, socio economy culture, and politic social, and environmental law aspects consisting of condition of environmental law enforcement and institutionalization of the authority to manage Batam City coastal zone for the implementation of sustainable development concept, 2) Determine the influence or association of policy in economy politic and environmental law of Batam City coastal zone toward the implementation of sustainable development concept The success of ecological conditions was determined by three assured prerequisites, these were. (1) spatial harmony, (2) assimilation capacity, and (3) sustainable exploitation. Political economy aspect was determined by two matters, which is the development policy chosen by government, in this case the authority of Batam City Coastal Zone, and the bureaucracy culture which produces good governance. Meanwhile, environmental legal aspect was determined by two indicators, that is environmental law enforcement and institutional of integrated coastal zone management. The imbalance of Batam City zoning which only sets aside 26% of non utilized land, high pollution level, and decrease of water quality indicated that within 30 years period of Batam City development, serious environmental degradation had taken place The environmental degradation was related to the inaccurate implementation of development policy which was characterized by high economy growth but was not accompanied by equal distribution and by the running of bureaucracy with high level of corruption, collusion, and nepotism, as well as by the development of Kontpradorisasi symptom. In addition to that, weak environmental law enforcement indicated by the limited number of cases of environmental law violation being legally processed (environmental lawsuit accomplishment), and the existence of ambiguous authority between Batam Authority and Batam City Local Government had shown that sustainable development of Batam City had not been undertaken or implemented yet.

Judul: Feeder kelinci ternak otomatis menggunkan prinsip aktuator solenoid
Abstrak: Feeder kelinci ternak otomatis merupakan prototipe yang diciptakan dengan pengaturan distribusi pakan berbentuk pellet pada konveyor sekrup termodifikasi dengan tambahan pintu akses teraktivasi oleh aktuator solenoid. Mikrokontroler Arduino Uno R3 pada prototipe ini digunakan untuk proses perhitungan jarak pintu akses, waktu tempuh pakan, dan kecepatan distribusi pakan. Prototipe ini bermanfaat untuk para pembudidaya/peternak kelinci sebagai inovasi teknologi dalam kegiatan pemeliharaan kelinci secara moderen. Pakan kelinci diatur melalui rotasi motor stepper pada penakar pakan sehingga dapat mengukur porsi pakan secara akurat. Penggunaan motor DC dilengkapi gearbox bertujuan mengendalikan konveyor sekrup agar berputar dengan konstan sehingga menghasilkan gaya dorong pada pakan yang akan didistribusikan. Hasil perhitungan kecepatan distribusi pakan menentukan waktu aktivasi aktuator solenoid yang akan membuka pintu akses pakan untuk keluar dari konveyor sekrup.
