Abstract

Research has been conducted to test silica function groups based on rice husks with temperature variations and concentrations of Cetyltrimethylammonium Bromide as raw materials for mesoporous silica. In this study, rice husk silica was synthesized by alkaline method with variations in CTAB concentrations of 2.0%, 2.5%, 3.0%, 3.5%, and hydrothermal treatments with temperature variations of 120, 130, 145, and 160ºC for 1 hour in an autoclave. Fourier-Transform Infrared (FTIR) results showed the presence of the most dominant clusters, namely Si-O-Si and other groups such as C-H, -H, O-H, and –OH. Therefore, silica-based rice husks can be used as raw materials mesoporous silica

Abstract

Traditional shrimp farmers at Sriminosari village still have problem to improve the productivity of their shrimp pond. Based on observation in the field, the low productivity of shrimp pond mainly due to the quality of water pond. Technology of the internet of things (IoT) is an alternative way to monitor some parameter their quality of water such as pH and temperature. Implementation of IoT will give a simple way to monitor the quality of water in a real time and continues. Technically, technology of IoT is not so expensive and easy to used for collecting data of quality water. So it is acceptable to implanted at Sriminosari village and useful to improve productivity shrimp farmer at Sriminosari village. Furthermore, information from IoT data will help farmer shrimp to reduce the risk in their business. Starting from a forum disscussion group (FGD), the technology IoT was introduced to some shrimp farmer at Sriminosari village. In general, The farmer gets basic knowledge about the concept of IoT including the implementation in the field. In this program, parameter pH and temperature was selected as model to monitor water quality of shrimp pond. The result of measurement data temperature on the field showed that an averaged value of temperature relatively stable in normal range 26-33⁰C, while the value of pH is various and tend to over the lower limit (< 6.0). Based on collecting data of temperature and pH on the field, it can be concluded that implementing IoT is very useful to assess the quality of water in shrimp farm. Furthermore, the respondents of shrimp farms indicated that implementation IoT in shrimp is acceptable and promising to improve their shrimp farm productivity.

Abstract

Teknologi ecoenzyme merupakan salah satu cara pengolahan sampah organik yang melibatkan proses fermentasi dikombinasikan dengan gula merah/molase dan air dengan perbandingan tertentu.  Cairan ecoenzyme yang dihasilkan merupakan bahan aktif yang dapat digunakan untuk berbagai kepentingan. Tujuan kegiatan ini memberikan edukasi kepada Tim Penggerak PKK Desa Fajar Baru dalam pengolahan sampah organik melalui teknologi ecoenzyme. Kegiatan dilakukan dalam bentuk ceramah, diskusi dan praktik pembuatan ecoenzyme. Secara keseluruhan kegiatan edukasi ini memberikan dampak positif bagi Tim Penggerak PKK Desa Fajar Baru. Hal ini ditunjukkan dengan peningkatan pengetahuan dalam pengolahan sampah organik untuk dijadikan bahan aktif dengan skor rata-rata 67,75 %. Berdasarkan hasil tersebut dapat disimpulkan adanya edukasi teknologi ecoenzyme dapat meningkatkan pengetahuan masyarakat dalam mengelola sampah organik di lingkungan.
