Judul: Simulasi Pertumbuhan Ayam Broiler Berdasarkan Variabilitas Iklim Mikro Kandang
Abstrak: Modelling is a relevant tool to monitor broiler rearing condition in integrated view. The aim of this study is to develop the simulation model of broiler growth realated to its interaction with micro-climate condition. Broiler growth model was simulated in relation with energy balance from feed that was intaked till its excreted. This simulation model can predict broiler live weight and feed intake variables. This model was validated using ideal and non ideal micro-climate condition as model inputs. Validation result show MRPE < 25%, means that this model accurate enough tobe used in another broiler growth simulation. This paper gives two simulation sample, it is simulation to see the effect of heat stress, and cold stress on broiler performance; and simulation to determine the best harvesting time. Based on feed convertion ratio (FCR) curve from first simulation, broiler that kept under effective temperature 34 oC (heat stress) has better feed efficiency than broiler that kept under Tef 10 oC (cold stress

Judul: Sistem supervisory control enviromental on model broiler closed house
Abstrak: Indonesia was a tropical country with high ambient temperatures for broilers since daily temperature reaches an average daily temperature of 360C (maximum) and 320 C (minimum); whereas the optimal temperature for broilers was in the range of 28-300C. Therefore, midle or large scale broiler industries have been using a control system to maintain the optimal temperature within a broiler house. Therefore, the role of a control system for regulating environmental parameters, not only temperature but also humidity, light intensity, and amonia content level, was very critical and relevant for better broiler production.The most important factors of comfort in broiler closed house including temperature, humidity, ammonia. Purpose were (1) designing the supervisory control system environmental parameters temperature, humidity and ammonia in broiler closed house, (2) assess the environmental characteristics of the parameters of temperature, humidity and ammonia in broiler closed house, (3) a model of environmental parameters of temperature, humidity and ammonia in the broiler closed house, (4) determine the optimal conditions supervisori control response parameter temperature, humidity and ammonia in broiler closed house, (5) the integration of environmental parameters supervisori control temperature, humidity and ammonia according to optimal conditions of control, knowledge of poultry and knowledge appropriate control environment in broiler closed house, (6) interconnect supervisory control environmental parameters temperature, humidity and ammonia in the broiler closed house in the form of software (software prototype) that can control one, two or three broiler closed house were connected to the computer network with remote with parallel computing. System of supervisory control for broiler closed house was a user interacts with the supervisory system to perform selection or determination of control modes, controlled parameters and optimality criteria for a certain poultry cultivated in a set of poultryhouses. Afterwards, the user preference specifications are passed to the Supervisory Control Engine (SCE) that performs the main supervisory computation scenario by utilizing the knowledge-base (control, climatic, broiler, and I/O knowledge). The SCE then produces set of control instructions to array of controllers that directly control and monitor a set of broiler closed house.The Control Knowledge-Base was a knowledge repository of various control methodologies, constraints, tools, and requirements. The Climatic knowledge-base stores all information about climatic parameters and characteristics. The poultry knowledge-base was a knowledge repository of poultry requirements, poultry types and characteristics. The I/O Knowledge-Base stores all relevant characteristics and usage requirements of I/O devices (sensors, transducers and actuators) that may be involved in a certain control scenario.The data used in this study included primary and secondary data. Primary data (floors, walls, rooms, and roof temperature) were obtained from measurements using an electronic measuring device. Secondary data (temperature, humidity, irradiation) was obtained from reports provided by BMG Bogor, including data processing model of moving heat broiler houses closed, predictive control parameters temperature, humidity and ammonia in Computational Fluid Dynamics (CFD), the results of mathematical modeling of temperature, humidity and ammonia obtained transfer function and the simulated supervisori control was ON- OFF control of Fuzzy Logic PID and ANFIS in the integration of one, two, three modes of control integration and interconnection networks in parallel computer simulations on

Judul: Kearifan Tradisional Perlindungan dan Pemanfaatan Sumberdaya Hutan oleh Suku Kanume di Taman Nasional Wasur
Abstrak: Wasur National Park (TN Wasur), is located in Merauke, Papua. The Kanume tribe is one of indigenous communities who have long been living in TN Wasur, which has the region's largest in TN Wasur, about 305.312 ha (73,78%). This study was conducted to analyze the pattern of protection and use of forest resources by the tribe Kanume in the Wasur National Park. The results showed that the people of clans in the ethnic of Kanume has a custom rules and wisdom in terms of protection and utilization of forest resources. Clans in the tribe of Kanume has ownership rights at the ulayat land to protect and exploit resources that there can be found sacred places, the old village, the well nature, hamlet of sago, and places the ancestral journey. In traditional wisdom and resource utilization, the tribe of Kanume have a culture that supports the management of the forest resource. This can be seen by the existence of the division of conception space based on the area of ulayat customs, the system of mastery and ownership of land, Sasi system and the belief of Totem(Totemism).
