Disease control efforts have been widely carried out, such as larvaciding, fogging focus, and mosquito breeding control. The efforts will be performing well if its involves community participation. The objectives of this study was to enhance community participation in the implementation of the mosquito control program of Dengue Hemorrhagic fever in Palupi and Singgani villages, Palu. The research design is a quasi experimental to analyze the difference between two approach, i.e. larvae surveyors (in Indonesia called as Jumantik) empowerment and the participation of the community leadres (in Indonesia called Ketua RT). Mosquito larvae survey was conducted with a single larval method. The population in this tsudy is all house in the two villages. Sample are consist of 100 houses in each village which were randomly selected. The result showed that during the first larvae survey in Palupi village, the larva-free rate (ABJ) was 68% with the result of CI, HI and BI were 20.81%, 32% and 46 respectively. In the village of Siranindi, the number of larva-free rate was 78%, with CI 19.64%, HI 22% and BI 33. At the seven weeks after the intervention with community participation  suggests that the larva-free rate in Palupi village was became 89%, with the number of CI 3.67%, HI 11% and BI 1%. While in Siranindi village, the larva-free rate was 85% with the CI, HI and BI were 8.4%, 15% and 21% respectively. According to that result, the most effective of community participation on DHF vector control is larva monitors (jumantik) empowerment.AbstrakDemam berdarah dengue (DBD) masih merupakan salah satu masalah kesehatan yang paling penting masyarakat di Indonesia.

Abstract

Bioelectrochemical Systems (BES) technology is a method for generating electric energy using bacteria as catalysts. The electricity is produced by Microbial Fuel Cells (MFCs), which represent the latest development in biological energy research. This study utilized substrates from banana stems and the bacterium Pseudomonas sp. The research aims to assess the potential of banana stems as a substrate in the MFC system and to determine the effects of adding a combination of an electrolyte solution and an appropriate buffering material to achieve maximum current, potential difference, and power density values. The results showed that the maximum current and potential difference achieved were 1.05 mA and 0.62 V, respectively, with a power density value of 446 mW/m². When combining the KMnO4 electrolyte solution with sodium phosphate buffer, a potential difference of 0.76 V and a current of 1.75 mA were obtained, resulting in a power density value of 911 mW/m². By using the K3[Fe(CN)6] electrolyte solution buffer with potassium phosphate buffer, a current of 1.14 mA was produced, and the power density value reached 406 mW/m².

Abstract

Ekstraksi minyak daun kemangi menggunakan metode Microwave Assisted Hydrodistillation (MAHD) telah dilakukan. Penelitian ini bertujuan untuk mengetahui daya dan waktu yang baik yang diperlukan untuk mengekstraksi minyak daun kemangi sehingga rendemen yang tinggi dihasilkan. Proses ekstraksi dilakukan menggunakan metode MAHD dengan pelarut air dan daya (400, 500, dan 600 W) serta waktu (30, 45, dan 60 menit). Karakterisasi minyak atsiri meliputi identifikasi warna, berat jenis, indeks bias dan kelarutan dalam alkohol 80% dan analisis GC-MS. Hasil yang diperoleh pada penelitian ini rendemen tertinggi minyak kemangi dengan metode MAHD sebesar 1.16% dengan daya 500 W selama 45 menit. Minyak kemangi yang dihasilkan berwarna kuning dengan indeksbias 1.48 dan berat jenis 0.95 g/m3. Minyak ini tampak keruh ketika dilarutkan dalam etanol sehingga diduga minyak atsiri yang diekstrak ini belum terlalu murni. Hasil analisis GC-MS dengan waktu retensi 30 menit menunjukkan bahwa minyak kemangi mengandung senyawa sitral (46.19%); neral (55.97%); geraniol (2.99%); geranil asetat (0.78%); dan linalool (0.76%). Dengan demikian, ekstraksi dengan metode ini sangat perlu dikembangkan agar kualitas minyak atsiri yang diperoleh lebih baik lagi.
