The following research work makes some reflections related to the waste caused by the harvests and the environmental impact that has caused by not using them properly. The methodology used for the analysis has related to the field visits carried out in a research project, obtaining as a result that a large amount of bagasse has poured into the ground, or burned causing pollution affecting the ecosystem of the territory studied, waste, integrated management, waste, bagasse pollution.</p> 2019-05-17T12:51:30+00:00 ##submission.copyrightStatement## https://sciencescholar.us/journal/index.php/ijls/article/view/294 Fortification of goat milk with purple sweet potato (Ipomea batatas l.) extract and its effects on functional cheese 2019-09-23T13:11:35+00:00 I Nyoman Sumerta Miwada miwada@unud.ac.id I Nyoman Sutarpa Sutama sutarpa_nym@unud.ac.id I Ketut Sukada ketut_sukada888@yahoo.com Lindawati Doloksaribu lindawati_doloksaribu@hotmail.com <p style="text-align: justify;">This study was undertaken to analyze the quality of goat milk based cheese particularly its potential high antioxidant content through fortification of goat milk with purple sweet potato extract. A completely randomized design was used to determine the characterization of goat milk based cheese quality through five levels i.e. 0% (A); 2% (B); 4% (C); 6% (D) and 8% w/v (E) of purple sweet potato extract fortification in goat milk. The results showed that the increased level of fortification by purple sweet potato extract in goat milk based cheese significantly increased the pH value of the cheese (P&lt;0.05) where the highest pH was 6.20 at the level of 4%&nbsp; w/v. Meanwhile, the yield and total of cheese acid were not affected by the fortification. The content of cheese protein significantly decreased (P&lt;0.05) by the increasing level of fortification by purple sweet potato in goat milk. Goat milk-based cheese on the E treatment contained the lowest protein (19.42%). Functional potency of the cheese increased significantly (P&lt;0.05) when the level of fortification was increased. The highest antioxidant content in goat milk based cheese was 114.47 mg/L. GAEAC at 8% w/v level. In conclusion, by increasing fortified goat milk by purple sweet potato extract up to 8% w/v was able to potentially produce cheese containing a high antioxidant.</p> 2019-07-01T15:29:46+00:00 ##submission.copyrightStatement## https://sciencescholar.us/journal/index.php/ijls/article/view/295 Impact of application of law no 16/2006 about fisheries and forestry agricultural extension system toward to performance of agricultural extension workers 2019-09-23T13:11:34+00:00 I Putu Addhi Krishnayana krisnaadi66@gmail.com I Nyoman Suparta partamas@yahoo.com Ni Wayan Tatik Inggriati tatikinggriati@unud.ac.id <p style="text-align: justify;">This study aims to analyze the relationship of knowledge, attitudes, skills, and characteristics with the motivation and performance of agricultural extension workers after implementing Law No. 16 of 2006. The research location was determined purposively. Sampling uses the stratified quota method. The data collection method is direct and in-depth interviews, observation and documentation. The results of the study showed that the average motivation and performance of agricultural extension workers were in the medium category. Knowledge, attitudes, characteristics, and skills of agricultural extension workers in Tabanan Regency proved to have a significant positive effect on instructor motivation and performance. Knowledge, attitudes, and skills of agricultural extension workers in Gianyar Regency proved to have a real positive effect on motivation and performance. The motivation and performance of extension agents in Gianyar and Tabanan Districts are mostly in the moderate category. The motivation of agricultural instructors in Tabanan has a very significant positive effect on the performance of extension agents, while the motivation of agricultural extension agents in Gianyar Regency has a significantly positive relationship to performance.</p> 2019-07-01T16:19:11+00:00 ##submission.copyrightStatement## https://sciencescholar.us/journal/index.php/ijls/article/view/299 Environmental impacts produced on earthquake in province of manabí 2019-09-23T13:11:34+00:00 Carlos Gustavo F.

When this phenomenon occurs, they endanger all elements of society; but not only that, because the consequences of these reach further and can compromise the environmental situation of a locality when they are able to produce changes in the orography of the land modifying the landscape. Many buildings collapse and others are affected, transforming the environment in an important way. The research aims to show some environmental risks that occurred when this type of natural phenomenon occurs, for which a bibliographic review was used as a methodology, appealing to the experiences derived from the effects of the earthquake in the city of Portoviejo on April 16 of 2016, where it was possible to see abandoned areas that previously had a high functional and social value, soils have acquired other types of values; but also where different environmental impacts and changes of landscape affected by natural phenomenon are observed.</p> 2019-07-10T05:13:09+00:00 ##submission.copyrightStatement## https://sciencescholar.us/journal/index.php/ijls/article/view/305 Utilization of piper caninum blume leaf extract combined with compost to suppress blast disease and increase the growth of local rice Bali (Oryza sativa) in Vivo 2019-09-23T13:11:33+00:00 Ni Luh Suriani niluhsurianisuriani@yahoo.com <p style="text-align: justify;">Blast disease is a disease that attacks rice plants. The control of this disease is still using a synthetic fungicide that is very harmful to the environment. The purpose of this research is to know the effect of the combination of <em>Piper caninum</em> leaf extract with compost to blast disease and rice plant growth. This research was conducted in vivo in the glasshouse of Senganan village, Penebel Tabanan. Bali. This study used a randomized block design. In this study, the extracts were combined with organic fertilizer which was made by biotechnology <em>stater starmic ok</em>. Fo = control (soil 100%). F1= (soil 90% + compost 10% + extract 0,5%) .F2 = (soil 80% + compost 20% + extract 1%) F3 = (soil 70% + 30% + extract 1.5%). F4 = (soil 60% + compost 40% + 2% extract), do repeat 4 times. The results show that the formulas F3 effectively reduce the intensity of blast disease by inhibition of 79.09%, significantly affect the number of rice leaves, and the number of rice tillers increases but in treatment, F4 decreased. The height of the rice plant from F1 to F4 decreases, it is great because it reduces the fall when the rice is fruitfull. This is due to the disruption of growth hormone by the extract.</p> 2019-08-07T13:54:42+00:00 ##submission.copyrightStatement## https://sciencescholar.us/journal/index.php/ijls/article/view/309 Effect of cod liver oil supplementation in commercial feed on reproductive organs weight and ovarian follicles size of local rabbits 2019-09-23T13:11:33+00:00 Ni Gusti Ayu Manik Ermayanti manikermayanti@gmail.com Ida Bagus Made Suaskara made_suaskara@unud.ac.id Iriani Setyawati iriani_setyawati@unud.ac.id Ni Made Rai Suarni gunggalih@ymail.com I Gusti Ayu Manik Widhyastini widhyastini2304@gmail.com <p style="text-align: justify;">This study aimed to determine the effect of cod liver oil supplementation in commercial feed on reproductive organs weight and ovarian follicles size of local rabbits. The experimental design used was Completely Randomized Design with four feed treatments, i.e. commercial feed without supplementation of cod liver oil (CLO) as control (P0), commercial feed supplemented by 3% CLO (P1), 4.5% CLO (P2), and 6% CLO (P3). Each treatment consisted of ten rabbits as replication and treatment were given to rabbits from aged 4 to 6 months. The parameters observed were the weight of the reproductive organs, namely the ovaries, fallopian tubes, uterus and the size of the ovarian follicles, namely primary, secondary, tertiary and preovulatory follicles of local rabbits. The results showed that various levels of cod liver oil supplementation in commercial feed differed significantly (P&lt;0.05) to the weight of the reproductive organs and the size of the ovarian follicles of local rabbits. It can be concluded that cod liver oil supplementation at 4.5% level in commercial feed capable increase the reproductive organs weight and ovarian follicles size of local rabbits.</p> 2019-08-15T02:09:28+00:00 ##submission.copyrightStatement## https://sciencescholar.us/journal/index.php/ijls/article/view/321 Short rest application reduce workload and musculoskeletal complaints public transportation driver 2019-09-23T13:11:33+00:00 I Ketut Sutapa ketutsutapa@pnb.ac.id <p style="text-align: justify;">It was needed an ergonomic work system to increase productivity for the vehicle driver work systems involves a lot of physical activity.
