Work as a palm oil mill worker is a job at risk of exposure to noise that exceeds the threshold value. The purpose of this study was to measure the intensity of noise on the occurrence of hearing complaints, psychological disturbances and Noise Induced Hearing Loss (NIHL) on workers and analyze the relationship of worker characteristics; age, length of service, use of Ear Protective Equipment (EPE) and knowledge of hearing complaints, psychological disorders and NIHL disorders. The research approach used in this research is survey method using cross sectional analytic research design with sampling using purposive sampling technique as many as 40 workers. Data were collected by measuring noise intensity, questionnaires and audiometry inspection. Data analysis using univariate and bivariate analyzes were processed using Spearman test. The result of the research shows that there is a considerable noise hazard in the work environment of PT. GBI, while the potential impact experienced by workers due to noise in low risk levels. The relation between factory noise intensity and worker characteristic; age, working period, knowledge and compliance of EPE usage in general have no significant relation to the incidence of hearing complaints, psychological disorders and NIHL disorders in workers, except in the variable level of knowledge with psychological disorders have a significant relationship.

This research was carried out in March 2021 to analyze the heavy metal content of Pb and Cu in the sediment and flesh of the horn shell (Cerithidea obtusa). Sediment samples and horn shells were taken from the coastal waters of Panipahan, Panipahan Village, and Teluk Pulai Village, Rokan Hilir Regency, Riau Province. The method used in this research is a survey method. Sampling was determined by using purposive sampling at three different stations. The results of this study showed that the metal content of Pb and Cu was highest in sediments around residential areas (44.7150 g/g and 104.4200 g/g), while the horn shell was found in areas far from anthropogenic activities (2.4717 g/g and 8.6617 g/g). Differences in the metal content of Pb and Cu in the sediments were found between stations, while for horn shells there was no difference between stations. The metal content of Pb in the sediment did not show a significant effect (F < 0.05) Pb content in horn shells, as well as Cu. The results of the calculation of the PTWI (Provisional Tolerable Weekly Intake) value indicated that the horn shell in the waters is acceptable for consumption

The present study aimed at identify population characters pollution source which affect water fertily nitrate, phospate, abundance as well as community structure of planctonic diatomae were measured. Nine sampling station of three location were established a long the Selat Air Hitam water. Appearently domestic activity, marine traffic, sago processing plant and community economic had affected on water fertility due to effluent water that entered the water. Nitrate analysis showed a range of 187,5 to 262,5 µg/L mean while phospate consentration appear 28,8- 241,2 µg/L, silicate consentration appear 30,4-32,9 µg/L. Plactonic diatomae abundance came up 2400 to 3800 cell/L of nine genera. Biodiversity index of range (1 kurang dari atau sama dengan H’ kurang dari atau sama dengan 3), while smiliarity index (0,5 kurang dari atau sama dengan E kurang dari atau sama dengan 1) and dominancy index (0,5 kurang dari atau sama dengan Ekurang dari atau sama dengan 1). Those index indicate nthe Selat Air Hitam waters in a medium pressure, however ecosystem condition is stable. Nitrate, phospate and silicate positively and significantly correlated with diatomae abundance ( p kurang dari 0,05). TSS level appeared 18,33 – 45,00 mg/l and BOD berkisar 3,73 – 5,07 mg/l. Regression analysis showed that nitrate and phospate had a mayor affect to diatomae abundance.

Gelatin is a protein from the hydrolysis of bone collagen and skin of animals wich are widely used for industrial food and non food. Studies on extraction of gelatin from tuna (Thunnus sp) bone were carried out by soaking in hydrochloric acid solutions of 4%, 6% and 8% for 48 hours respectivelly and extracted with aquadest at 60ºC, 70ºC and 80ºC for 5 hours. The extract was filtered with filtering cloth and the filtrate was oven dried at 55ºC for ± 48 hours until gelatin was formed. The result showed that soaking the bone in 8% hydrochloric acid solutions followed by extraction 80ºC for 5 hours gave the best result with 8,64 yield, isoelectrict point 8,20%, protein contain 93,72%, lipid contain 0,74-1,75%. Gel strengh 257,59 g/bloom gel strengh, viscosity 3,20 cPs, pH 3,98. The results obtained for water contain of 6,97%. Ash countain 2,07%. The colour of gelatin produced from tuna bone showered different with commercial gelatin that is between yellowish brown to whitish yellow. Gelatin made from tuna bone has fishy odor whereas commercial gelatin has neutral odor.

Primary data obtained from interviews with local government officials, companies and community leaders who were selected purposively at the research location. Secondary data were obtained from village offices, BPS, books, research journals related to agrarian conflicts in the plantation sector. The data collection technique used the triangulation method to obtain valid data. Furthermore, the data were analyzed descriptively. The conflict analysis method used in this study uses a problem tree so that the root of the problem and the causes and consequences of the conflict between the community and the company can be explored. The roots of the problem include the non-fulfillment of the KKPA land and a lack of understanding of land rights. This is caused by a lack of communication between the company and the community, resulting in conflicts. Efforts to resolve conflicts between companies and communities need to be carried out, especially by using an ecological approach.
