The Plants Extract Toxicity Againts Achatina fulica (Ferussac, 1821) in Nyawai Ficus variegata (Blume)

Abstract: One of the problems in developing Nyawai plants is the attack of snail pests Achatina fulica (Ferussac, 1821) at seedling level of the plants Plant damage caused by these pests is quite large and causes seedling death One of the control efforts that can be done is utilizing biomaterials which have molluscicidal properties (can kill mollusks) This study aimed to determine the toxicity of some extracts of biomaterial to control Achatina fulica (Ferussac, 1821) pests The research was conducted on a laboratory scale The study used a factorial random design with 3 replications The treatment consisted of four biomaterials namely sembung (Blumea balsamifera), gadung (Discorea hispida), tuba (Derris eliptica and betel nut (Areca catechu) with each concentration of 102550 g/l Each concentration used 4 snails as a test sample The parameters observed were snail mortality, and Lethal Concentration (LC50 and LC95) The results showed that the gadung tuber extract had the highest toxicity as indicated by mortality of 75 % and the lowest LC95 value of 8063 g/l While the lowest toxicity is betel nut with mortality of 4975 % and the highest LC95 value is 56775 g/l The Toxicity of tuba, pinang, and sembung are highest on 50 g/l concentration, excepted the gadung extract In gadung extract, the highest toxicity was obtained on 10 g/l concentration However, the application was consideration to the attack intensity of Achatina fulica (Ferussac, 1821) because the toxicity effect of biomaterial pesticide was slower than chemical molluscicide Keywords: Achatina fulica (Ferussac, 1821), biomaterial, concentration, toxicity

Wildlife Diversity for Ecotourism at Aqua Lestari Forest Park, North Minahasa

Abstract: The purpose of this study is to know the potential diversity of wild fauna (birds, butterflies, reptils , and mammals) in THAL. Inventory of mammal, reptile , and butterfly using line transect method while birds were observed by Ponctuels d'Abundance Indices method (IPA ). The results showed that the potential fauna can be found in THAL as many as 49 species consisting of 36 species of birds, eight species of butterflies, three species of reptiles , and three species of mammals. From 49 fauna species at least nine species were endemic to Sulawesi and 11 species protected by Indonesian law. In the future development of THAL area, it is expected that management will conserve the condition of wildlife habitat in order to stay natural.

Processing and Added Value of Bamboo in Tasikmalaya, West Java

Abstract: Bamboo is a multipurpose plant that has been used by the people for generation s This study aimed to describe the processing of bamboo and analyze its added value in Tasikmalaya Regency, West Java Data was collected in April -December 2016 through interviews using questionnaires and field observations of bamboo craftsmen, and then were processed and analyzed quantitatively and descriptively The community processed bamboo into woven products such as ayakan , boboko, haseupan, hihid, picnic basket, nyiru, pipiti, and parcel, as well as non-woven products such as piggy banks, key chains, glasses, wall clocks, lampshades, invitation boxes, bowl, cup, frame, teapot, letter box , and tissue box The average added value of woven products was IDR 131,19721 or 911 % of the non-woven products , which was IDR 1,439,74242 The average added value ratio of woven products is 0 , 83 and 0 , 90 for non - woven products B amboo woven b usiness for household products is mostly done because the market has formed, stable, and has a wider scope even though it has lower added value The market of non-woven products is smaller and spe c ific even though it has a higher added value A bamboo stem is only valued IDR 10 , 000 – 50,000 , so it shou l d be sold in processed product s rather than the original form Keywords: bamboo, processing, added value, woven, non - woven

Potency and Agroforestry Patterns that Support Bamboo Sustainability in Sukaharja Village, Ciamis District

Abstract: Some people still thinks that bamboo has a low economic value. Many bamboo plants in the community are removed or replaced with other commodities. Sukaharja Village in Ciamis Regency is one of the centers that produce of bamboo.

Vegetation observation and measurement was done by census (100 %) in all selected land area so that all types of compiler can be known. Parameters recorded/measured were bamboo species, number of clumps, number of tillers, number of young stems, number of old stems, stem height and stem circumference. Data related to socioeconomic obtained through interview. Respondents interviewed was chosen purposively by 69 respondents. Secondary data was obtained from literature study and data from agencies that are related to research objectives, such as District Forestry office, village office, and Agricultural Extension Agency, Fisheries, Livestock and Forestry.
