Abstract

People on Benteng Tengah, Nangamese and Latung have been living in Flores Island and smaller island nearby Flores, like Ontoloe, long before the establishment of national park. In 1992 and 1996, the government established Nature Conservation of Wolo Tado, Nature Conservation of Riung and Marine Nature Conservation of 17 Pulau. This decision led to government’s policy to prohibit the opening of land by burning. Local people used to open a land for agricultural purpose by setting a fire in order to regenerate the savanna to promoting the growth of young grass leaves. People use young grass to feed their cattle. This prohibition causes the people had to herd their cattle far from they live. As the consequence, threat from Komodo (Varanus komodoensis) to attack cattle is increased and people consider Komodo as pest that has to be terminated. This research aimed to study people’s knowledge about Komodo status as endangered species and its implication. Data were collected from people who lives in Benteng Tengah, Nangamese, and Latung, Regency of Ngada, East Nusa Tenggara. Data were obtained from respondents using interviews and questionnaires. Perception of local people who lives in Benteng Tengah (93%), Nangamese (93%) and Latung (100%) showed that people are aware about Komodo’s habitat vegetation. Good perception on Komodo and habitat vegetation will maintain komodo sustainability.

Abstract

Literacy is believed to contribute plenty of benefits to both students and community helping them understand problems more clearly. One way to develop literacy is through building up reading habit. The border community, residing the border of Indonesia and Timor Leste, badly needs the literacy development both conceptually and feasibly through some practical techniques. One of the methods offered here is Mind Mapping. Mind mapping method gave benefits for users effectively and efficiently when they had implemented it simultaneously. People could write and took main issues from materials studied and kept long term. This activity was targeted at the OKL Street Library community or users that comprised students and volunteers who actively interacted at the OKL Street Library reading Venue. The aim to be achieved, was the enhancement of students and volunteers’ knowledge and skills towards a concept or a learning material in a more creatively, innovatively and participatorily by utilizing the mind mapping method. Students were also given a couple of books to increase their literacy culture. Such activity was carried out with the coordination of OKL Street Library, in terms of problems identification, determining the problem focus and for the mind mapping practiced and also books sharing which was collectively implemented by the team-work. Every students, volunteers and OKL SL founder felt happy and got benetif of these activities included understanding mind mapping and created point of view about how to maintain home and class freshly. The students modified it to state daily habits to be successed in their hobbies in future. We were looking forward to having more such activities or other development activities specially for lower primary students at OKL SL to help them enhance literacy competence that could benefit the whole community.

Abstract

Research has been carried out on the BorazSiLab Filter design and performance used filtration system. The selected filtration mechanism is a multi-stage filtration system. The filter material used is lontar shell activated charcoal, coconut fiber, sand, and zeolite. The purpose of this study is to test the performance of the tool (effectiveness and efficiency) filled with the four materials above. The implementation stages of this research are divided into two, namely fabricating the BorazSiLab Filter tool and testing the reliability of tool. To facilitate tool fabrication, it is necessary to design tools in the form of working drawings of 2D shapes and 3D geometry so that they are easy to understand. The reliability test was carried out on the dimensions of the filter box, the surface area and volume of the material, the filtration discharge, and the water quality (pH, temperature, odor, and colors). The results showed that the tool was made of a glass box measuring 20×20×20 cm. The filtration time is fixed at 45 minutes. The measured filtration efficiency and effectiveness of the filter material surface area, filter media volume, filtration discharge before (Qin) and after (Qout) filtration are 0,0022 m2 (one tea bag) to 0,0044 m2 (two tea bag); 3,3×105 m3 (one tea bag) to 5,81×105 m3 (two tea bag); 1,1423 L/s; and 0,00046 L/s. Preliminary tests for water quality before and after for the parameters of odor, pH, and temperature values, respectively, are odor to odorless; colored to colorless pH = 7; temperature = 26,1 ± 3 °C to 27,9 ± 3 °C. Therefore, the BorazSiLab Filter can be used as a filtration tool for wastewater treatment.
