<p class="Default"><em>Coconut coir can be processed into cocopeat and coco fiber. In the chopping process, the chopping mechanism has a critical role that will determine the results of the chopping off of coconut coir. Based on these conditions, in this study, the development of a chopping mechanism was carried out by modifying the chopper blade to improve the chopper of coconut coir. The purpose of this study was to modify the coconut coir chopper blade, perform performance tests and calculate the increased performance after modification. Modification of the chopper mechanism on the coconut coir chopper machine is done by replacing the type of chopper blade with an iron rod with a diameter of 4 mm which is sharpened at the end. The test data includes data on the capacity of coconut coir chopping, the percentage of cocopeat, the percentage of coco fiber, the percentage of unprocessed coconut coir, the percentage of material loss, and the increase in performance after modification. The modified coconut coir chopper mechanism has specifications of 240 mm long, 100 mm diameter, 39 blades, and ± 14 mm high. The test was carried out at a rotary speed of the chopper mechanism of 720 rpm. Based on the test result, the capacity of chopping coconut coir using a modified coconut coir chopper machine is 7,93 kg/hour, producing 45,57% cocopeat, 36,15% coco fiber, 13,15% coconut coir unprocessed and the loss reached 5,13%. Modifications on the chopper blade are proven to increase the performance of the coconut coir chopper machine by 297%.</em></p>

ABSTRAK   Kabupaten Sambas merupakan salah satu sentra utama produksi padi di Kalimantan Barat. Kabupaten ini berada di wilayah perbatasan antara Indonesia dan Malaysia. Desa Tebas Sungai merupakan satu diantara sentra padi yang pernah gagal panen diakibatkan serangan tikus pertanian pada bulan Juli 2016. Mitra kegiatan Penerapan Penerapan Teknologi Tepat Guna kepada Masyarakat ini adalah Kelompok Tani Candra Mekar dan Sari Melati Kencana yang berada di Desa Tebas Sungai Kecamatan Tebas Kabupaten Sambas.  Kelompok ini relatif tertinggal dibanding kelompok tani lainnya di kecamatan disebabkan kurangnya bantuan di bidang pertanian. Persoalan yang dihadapi mitra secara umum adalah serangan hama tikus, serangan hama wereng coklat, penggerek batang, lembing batu, tungro, blas, dan hawar, kurang jumlah dan efektifnya penggunaan mesin perontok padi, ketersediaan pupuk subsidi yang sangat terbatas, dan irigasi belum bisa dilakukan dengan baik akibat terbatasnya pompa. Solusi yang disepakati dari permasalahan prioritas mitra adalah pengendalian tikus pertanian, pengendalian hama serangga menggunakan perangkap serangga (light trap), serta pembuatan dan pengelolaan mesin perontok padi untuk penanganan pasca panen. Target luaran kegiatan ini antara lain: 1) Program pengendalian tikus pertanian menghasilkan luaran alat perangkap tikus pertanian berjumlah 10 set, terselesaikan 10 set; 2) Program pengendalian hama serangga menggunakan perangkap serangga menghasilkan luaran 10 set, sudah tercapai 10 set; dan 3) Program pembuatan dan pengelolaan mesin perontok padi menghasilkan luaran mesin perontok padi sebanyak 2 unit, terealisasi 2 unit; 4) Publikasi pada jurnal ber-ISSN DIPAMAS; dan 5) Publikasi kegiatan pada media massa (online 1 kali terealisasi 4 kali, CSMTV 1 kali sudah terealisasi dan telah diupload pula di youtube.com, dan surat kabar/media massa realisasi 2 kali versi cetak). Kegiatan PPTTG ini melalui tahapan-tahapan: 1) Program pengendalian tikus pertanian; 2) Program pengendalian hama serangga; dan 3) Program pembuatan dan pengelolaan mesin perontok padi. Secara ekonomi, adanya penerapan teknologi melalui PPTTG akan mencegah kerugian dalam usahatani padi (akibat serangan tikus sawah), mengefektifkan pencegahan serangan hama (melalui perangkap hama/light trap), dan mengefisienkan biaya pasca panen padi (dengan alat perontok padi). Secara keseluruhan dampak ekonominya dapat menyebabkan peningkatan pendapatan petani padi sawah sehingga diharapkan mampu mensejahterakan ekonomi masyarakat tani. Secara sosial, dampak yang didapat dari penerapan teknologi adalah adanya ketenteraman di masyarakat karena adanya alat yang mencegah terjadinya kerugian dalam pengusahaan budidaya tanaman padi, serangan hama maupun penyakit yang dibawa oleh hama, dan tidak lagi terjadi rebutan antrian terhadap mesin perontok padi karena telah ada alat yang diberikan kepada kelompok.   Kata kunci: hama, padi, perangkap serangga  

The availability of clean water still poses problems in Indonesia. The need of clean water for Sambas City people still depends on river water. This river water comes from Sambas River which has bright yellow color (73.6 TCU), exceeding the allowed maximum level for clean water in accordance with the Regulation of Health Affairs No.416/MEN.KES/PER/IX/1990, which is 50 TCU, with low turbidity (23.3 TCU) and low pH (4.34). The characteristics of this river water indicate that the water color of Sambas River is true color. Level of this type of water color can be degraded by adsorption process using activated charcoal. It is easy to find raw materials of activated charcoal from waste sources containing carbon in Indonesia, especially West Kalimantan, such as bagasse, wood chips and coconut shell. Therefore, this research was conducted to identify the influence of activated charcoal types of bagasse, wood chips and coconut shell which are used as adsorbent to adsorp the color of Sambas river water and to identify the optimum dosage and duration of the process.Activated charcoal was made of bagasse, wood chip and coconut shell through pyrolysis process at a temperature of 500 0 C for 3.5 hours followed by chemical activation process using H3PO4 5% for 24 hours. The water was from Sambas river, Tanjung Mekar Village, Sambas, West Kalimantan. The adsorption process employed various types of activated charcoal (bagasse, wood chips and coconut shell); dosage (1, 2, 3, 4 and 5%b/v); and contact time (10, 15, 30, 60, 90, 120 and 180 minutes).The results indicated that different types of activated charcoal material in the adsorption process give different color level. The best treatment of batch process with 500 ml of Sambas river water was from the adsorption using activated charcoal of bagasse with an optimum dosage of 2% b/v and optimum contact duration of 90 minutes. It produced water color level between 50.00-52.00 TCU (meeting the standard of the Regulation of Health Affairs No.416/MEN.KES/PER/IX/1990).
