This study aimed to determine the effect of boiling time on polyphenol compounds and antioxidant activity ciplukan (leaves, stems, fruit, roots and mixture of each plant part). This research used Randomized Block Design (RBD) with five groups (leaves, stems, fruit, roots, and mixture of each part of the plant ) and three treatments (10, 20 and 30 minutes). The analysis for the experiment were the antioxidant activity of each part of the plant by using various incubation time, the antioxidant activity and total polyphenol for each treatment. The results showed that the duration of boiling had a significant effect on total polyphenols but no significant effect on antioxidant activity. The highest total polyphenols were obtained on leaves with 30 min boiling duration (1210.5 mg GAE / g), and the highest antioxidant activity was also obtained on leaves with 30 min boiling time (88.32%).

Ladu cake is a traditional cake originating from the Pariaman area which has a savory and crunchy taste and a unique shape. This study aims to determine the effect of the ratio of dry grated coconut on the characteristics of the Ladu cake, to determine the effect of the best comparison level in producing the best product and to determine the storage time of the best Ladu cake. This study was designed using a completely randomized design (CRD) with 5 treatments (comparison of rice flour and dry grated coconut 100%:0%; 95%:5%; 90%:10%; 85%:15%; and 80%:20 %) and 3 replicates. The results showed that the ratio of dry grated coconut had an effect on moisture content, ash content, fat content, carbohydrate content, crude fiber content, friability, color, aroma, texture and taste. However, it had no significant effect on protein levels. Based on the chemical, physical and sensory characteristics of the comparison of Ladu cake products, the best product was obtained in the 10% dry grated coconut and 90% rice flour treatment with the characteristics of this treatment being 1.96% water content, 2.42% ash content, fat content 19.55%, protein content 7.56%, carbohydrate content 68.86%, crude fiber content 2.73%, and the average value of sensory analysis of aroma 3.70, color 4.07, texture 3.53 and taste 3.97.

Pest attacks on rice plants can cause a detrimental decrease in production. Hymenoptera has many important roles in ecosystems, including as parasitoids and predators of pests. The purpose of this study was to determine the presence of Hymenoptera around tidal swamp rice in Indragiri Hilir Regency, Indonesia. Sampling used four traps, namely: 1) swing net; 2) yellow pan trap; 3) malaise trap; and 4) pitfall traps. The analysis was carried out by calculating the Shannon-Wiener diversity index (H'), the Margalef species richness index (D), the Pielou species evenness index (J). Hymenoptera found around tidal swamp rice areas of Indragiri Hilir Regency were 15.253 Hymenoptera insects consisting of 11 superfamilies, 37 families, and 304 morphospecies. Hymenoptera parasitoid had the highest diversity index value (4,80), followed by Hymenoptera pollinator (3,13) and Hymenoptera predator (3,11). The number of species of Hymenoptera parasitoid, pollinator, and predator obtained was 243; 31 and 76 species. The high diversity of Hymenoptera around tidal agricultural land optimizes its ecological role in the rice plantation ecosystem.

This research executed in Siberut island which has been specified Unesco as Biosphere Reserve. The purpose of research was to identify the policy which has been specified in Siberut, knows implementation of management, knows perception and participation of public and knows interaction of the parties involving in management Biosphere Reserve. Method applied is Inventory and contents analysis of policy, Indepth Interview with cross check, Open interview with descriptive qualitative and Inventory and Stakeholder analysis. Republic of Indonesia Government doesn't support expansion of Siberut Biosphere Reserve for all island. There is understanding difference and exploiting of Biosphere Reserve according to the Government with MAB-UNESCO so do with perception there are difference between publics Siberut with the Government. Local public assumes that forest Siberut is custom forest which its the domination stays at custom public according to custom Arat Sabulungan, where its the exploiting and management is done based on custom, but the Government considers to be state forest. Implementation of Siberut Biosphere Reserve Pledge based on Indicator Implementation released by Unesco, 1996 till now still uncommitting for overall of area Biosphere Reserve, except to of Core area (Siberut National Park). Implementation at core area based on Indicator Implementation (Unesco, 1996) mostly has been executed, except for Indikator 5,6,8,9 and 16. Role and influence MAB and TNS in Siberut still be low for the reason need to be improved. Keyword: Cagar Biosfer Siberut, Siberut Biosphere Reserve.

A complete calibration test stand was constructed and instrumented to examine the effect of varying pitch and roll positions on the measurement errors of a microwave solid type flow sensor. Results indicated that measurement errors ranging from 2.50% to 6.82% and 1.80% to 8.86% were obtained by the changing of chute pitch (descending and ascending) and roll angle positions from 1.5° to 4.5°, respectively. Greater measurement errors were found at the low screw auger conveyor speed range. However, the magnitude of errors is within the acceptable margin for any typical wet paddy land topography.
