Item ANALISIS TUGAS POKOK DAN FUNGSI BALAI BESAR KONSERVASI SUMBER DAYA ALAM PROPINSI RIAU 2010-2015(2019-11) Putri, Annisa; Darwis, RobiThis research was conducted at the Center for Conservation of Natural Resources in Riau Province. The purpose of this study was to analyze the main tasks and functions of the Center for Conservation of Natural Resources about forest fires in Riau province in 2010-2015. The data collection techniques used by the author in this study were purposive techniques. sampling, interviews, observations, and then the analysis technique I use in this research is descriptive qualitative, the collected data is processed into analysis by describing and linking theories in accordance with existing problems to answer each problem and then provide interpretation For Relevant Results, conclusions and suggestions are then drawn. In this research, the researcher chooses key informants and informants who use the purposive sampling technique in which the researcher chooses key informants and informants who the researchers consider to be aware of the problem, namely the head of the general subbag, the head of protection control, the head of the program and cooperation subdivision, the head of the Utilization and Services Section, the head of the division Forest fire control, Subdivision Data Evaluation reporting Public relations data, based on research has been carried out, it can be said that the implementation of the main tasks and functions of the Conservation Center are in accordance with the Minister of Environment and Forestry Regulation No. 8 of 2016. Regarding the implementation unit of the Technical Conservation of Natural Resources holding functions in his work area. In Riau Province.Item PEMBUATAN SISTEM HIDUNG ELEKTRONIK OPTIK UNTUK MENENTUKAN KEMATANGAN BUAH SAWIT(Elfitra, 2022-04) Putri, Annisa; Minarni, MinarniThe ripeness level of oil palm FFB is one of the important factors that need to be considered in efforts to improve the quality of palm oil. Currently, an optical electronic nose system has been developed which is a development of the ordinary electronic nose system. Optical electronic nose system is widely used to evaluate fruit quality by determining the degree of ripeness. In this study, the optical electronic nose system was designed to characterize the maturity level of oil palm FFB by paying attention to the sensor output voltage at each maturity level fraction. This system utilizes an FDS100 photodiode detector as a sensor and an infrared LED as a light source. The sample used was tenera type of oil palm FFB with 3 variations in maturity level, namely raw (unripe), ripe (ripe), and overripe. The system consists of a sensor chamber which contains an LED and a photodiode, a sample chamber and a simple electronic circuit. The detection process was carried out on the fruit of the oil palm.The output voltage measurement was carried out using the PLX-DAQ program which has been connected to the Arduino Mega 2560 program. The data processing uses a python-based program with a numerical integration method using trapezoidal rules. The area of the trapezoidal region represents the voltage generated by the photodiode. The output voltage on the sensor was processed and further analyzed as a trapezoidal area to obtain the maturity classification results. The results showed that there are significant differences in voltage values from the detection results made by the photodiode sensor for the three maturity fractions. The value of the voltage generated in the overripe sample is higher than that for the ripe sample and the raw sample. The graph shows that the overripe sample has a lower peak. This means that the gas particles produced from the overripe palm sample are more than that for the other palm oil samples. This proves that the optical electronic nose system designed is able to detect the maturity level of the oil palm FFB well.
