Indonesia categorized as a mega-biodiversity country, with 25% of the species in the world. One of the uses of natural resources is in the tourism sector. Lately, in Indonesia, research about Social Media and Ecotourism is still not much done. Some studies in Indonesia mostly still view social media as marketing advice. In fact, social media also plays an important role in regulating the perceptions of the people who come to the ecotourism site both from the content or the ease of access. Practically this research can be used as a strategic reference by stakeholders, to be able to use Social Media as media for promotion and education. Then academically, this research can be a reference for further research on the strategy of managing ecotourism with social media. This research is a descriptive type with quantitative and qualitative approaches, with research locations in Malang. Research using an online questionnaire with Google Form.

Taman Beach as one of the superior tourist destinations in Pacitan has now begun to develop. The development of Taman Beach tourism object is inseparable from the efforts which are initiated by the Group of Turtle Rescue Society for Tourism "Taman Ria" which develops turtle conservation activities through the concept of community-based ecotourism. Local people have also developed tourist attractions such as flying fox and swimming pools to attract tourists to visit it and a portion of the tourism incomes for the funding of turtle conservation activities. However, in the development process, there are problems such as the low level of community participation and the lack of management of tourist object that is integrated with the local community.This study aims to analyze the role and level of community participation in supporting the development of community-based ecotourism in the Taman Beach area. The method used in this research is descriptive quantitative. Quantitative data analysis using the Multidimensional Scaling (MDS) approach. Data collection is done by using questionnaires and observations in the field. The variables studied included the dimensions of planning, management, monitoring, and supervision. The results of the study indicate that the involvement of local communities in the development of ecotourism does not support sustainability, with an average sustainability index value of 46.864. The level of community participation according to Arnstein's participatory ladder from the aspect of planning and management aspects has reached the level of placement participation in the tokenism category (accepting the provisions). Whereas from the aspect of monitoring and controlling has reached the level of consultation participation in the tokenism category (accepting the provisions). The results of the analysis show that policy strategies are needed to increase community participation through increasing community roles and responsibilities in planning, management, monitoring, and controlling. Keywords: community based, ecotourism, multidimensional scaling

In addition to a wide range of adverse effects on human health, toxic metals such as cadmium (Cd) can promote kidney damage. In this study, we proposed the toxicological properties of these metals which are partly related to lipid peroxidation and chlorinative stress. Thus our study aimed to measure the lipid peroxidation and chlorinative stress in kidney of rats exposed to Cd. The study was performed on 32 male rats (Rattus novergicus) weighing 300±10 grams with normal activity. Rats were acclimatized for a week before the treatment. The animals were divided into two major groups with one group for control (K0) and the other groups were exposed to 3 mg/L CdSO4 through the drinking water. The animals in each groups were divided again into two small groups with different time of exposure. The time of exposure are subacute (six weeks) and subchronic (eight weeks). After the exposure the kidney from all treated animals showed the significant increase of MDA and AOPP levels. In conclusion, subacute and subchronic exposure of Cd caused the kidney damage through lipid peroxidation and chlorinative stress, as shown by increasing of MDA and AOPP levels. Keywords: AOPP, Cadmium, Chlorinative Stress, Lipid Peroxidation, MDA

In aquaculture of an irrigation, the use of cypermethrin-based pesticide can harm nile tilapia which cultured within and its impact on humans who consume the fish. Thus it is necessary to study to determine the threshold of this cypermethrin-based pesticide. Determining the thresholds was using the test of LC50 - 96 hours (Lethal Concentration 50-96 hour) which tested tilapia that dead by 50%, which can be used as a benchmark threshold for cypermethrin-based pesticide. Test of LC50 - 96 hours consist of preliminary test and advanced test. Lethal Concentration 50 (LC50 - 96 hours) of cypermethrin-based pesticide towards nile tilapia (Oreochromis niloticus) is 0.082 ppm. At these doses, tilapia death reached 50%. This concentration is expressed as a threshold usage of cypermethrin-based pesticide on the environment around the aquaculture of tilapia. Keywords: Cypermehrin-based pesticide, LC5096 hour, Nile tilapia.

This study was conducted to evaluate the effect of Moringa oleifera leaf and seed extract on length, weight, and feeding activity of Spodoptera litura. Leaf and seed were extracted by maceration method in 70% ethanol. Bioassays were conducted by using five concentrations (0%, 5%, 10%, 15%, 20%) on 5 larvae by leaf-dip method with 5 times replication. The result showed that leaf and seed of Moringa extract contained alkaloid, flavonoid, and saponin which gave antifeedant effect to growth and feeding activity of larvae. The increased extract concentrations are lead to weight loss and the length shrinkage of larvae. The extracts promoted prolongation of the larval instar. Reduction of food intake of the larva is in line with the concentration increase of extracts. The antifeedant effect also affects time to stop feeding and give mortality of larvae.Keywords: antifeedant, leaf, moringa, seed, S. litura

This study aimed to screen some potential local seed grains for hydroseeding and describe their characteristics based on the literature review and a year of hydroseeding application. This study used six species/variants of Poaceae (Coix lacryma-jobi, Eleusine indica, Setaria italica (brown, black, and red), Sorghum timorense, S. bicolor, Themeda arundinaceae), five species of Leguminosae (Adenanthera pavonina, Cajanus cajan, Sesbania grandiflora, S. sesban, Indigofera sp.), a species of Cyperaceae (Cyperus javanicus), Sapindaceae (Sapindus rarak), Rhamnaceae (Ziziphus jujuba), and Moringaceae (Moringa oleifera). A seed germination test was held using soil media placed in 5 pots per species until 15 days after sowing (DAS). Characters were scored, and data were statistically analyzed. A field record of one-year hydroseeding applied on 6 m x 6 m post-coal mining land plot was presented. Some data such as pH H2O, pH KCl, conductivity, and soil organic carbon among hydroseeding areas, unrevegetated areas, and reference sites were observed. Results showed that there were 13 of 17 species could variably germinate. The fastest germination time was recorded for S. timorense, S. bicolor, red S. italica, C. cajan, and S. grandiflora, while the highest germination rate (â‰¥50%) was black S. italica (80%), brown S. italica (58%) and S. bicolor (50%). The annual black and brown S. italica, S. bicolor, and S. timorense were highly recommended to be used in hydroseeding. The perennial C. cajan, Indigofera sp., S. sesban, and T. arundinaceae were also potential to be added into a hydroseeding slurry to improve pioneer vegetation multilayering structure and diversity.
