This threshing process is carried out so that small palm fruit or oil palm fruit bunches weighing under 5 kg can be accepted at the palm oil mill. In general, fresh fruit bunches (FFB) weighing under 5 kg are not sold, so before being brought to the palm oil mill, they must be threshed first so that the palm becomes loose or granules that can be accepted by the palm oil mill. Designing a model of a palm fruit threshing machine from the bunches aims to increase profits for palm oil entrepreneurs, because small palm fruit can be accepted in palm oil mills. In this design, the thresher model is made, the engine uses a diesel motor, WPA 60 1:40 gearbox, rubber clutch and the capacity of this palm thresher machine is 150 kg/hour. Testing of the palm thresher machine is carried out in three types of tests, the results of production capacity and fuel use. The production capacity of palm fruit obtained is 324.6 kg/hour while the use of fuel is 900 ml/hour

The influence of rotation engine speed to coco fiber and coco peat yieldof coconut fruit from Jambi area has been done. The study aims to know the percentage of cocofiber and cocopeat produced based on the influence of rotation engine speed of decomposition machine starting from 225 rpm, 450 rpm, 750 rpm and 900 rpm. Each round speed will operate for 2 minutes with 500 grams of raw material and use variation 5 and10 decomposing blades. The result show that(1) the rotational speed of the decomposition machine affects the amount of cocofiber and cocopeat produced. The highest percentage of cocofiber and cocopeat is at 450 rpm (2) The number of blades of the decomposition machine against the percentage of cocofiber and cocopeat produced. The highest percentage of cocofiber and cocopeat using 10 blades. (3) The maximum result of cocofiber and cocopeat obtained from engine speed 450 rpm is 28% cocofiber and 50% cocopeat.

Rubber plant is one of the potential plants, the production of latex from the rubber plant is used as a raw material for making rubber bands, and the cutting process is required by a rubber band cutting machine. The purpose of the performance analysis of this rubber band cutter is to find out the cut / minute results of this machine and the machine uses a 1.5 HP electric motor with a reducer ratio of 10: 1 and get a 110 Cut / minute result and from the results of data retrieval using a thick cutting knife 5 mm on average this machine can print granules with a thickness of 2 mm. As for this machine, it will be sold at a more economical price and uses a level of electricity consumption that is not wasteful compared to machines that are already on the market.

The purpose of this study was to determine the performance of a hybrid dryer by combining the utilization of solar energy (solar dryer) and biomass power sources. Utilization of solar thermal energy sources by maximizing solar heat radiation sources which are absorbed directly into the drying chamber in the form of a transparent house with ventilation holes for fresh air to enter and moist air to exit. This process will produce hot air circulation (convection) in the drying chamber continuously so that the process of evaporation of water from the material being dried is faster. The temperature of the hybrid dryer with a sun source without the test material was 56º C. In the hybrid dryer test with a biomass combustion power source without the test material, the maximum temperature was 46 º C with a stable temperature of 40 º C. In the hybrid dryer test with a solar power source with the material test with a drying rate for 6 hours of drying there was a reduction in the mass of areca nut by 19%. The performance of the hybrid drying machine is better when the temperature is controlled with a setting temperature of 60º C. The average drying rate of areca nut from the hybrid dryer is 1 kg/hour

Implementasi Penggunaan Driving Monitoring System (DMS) Sebagai Kendali Bahaya Dari Aktivitas Pengoperasian Unit Pengangkutan Batubara PT.

Latar Belakang: Implementasi teknologi pada kegiatan operasional perusahaan adalah sebuah keniscayaan, jika perusahaan ingin tetap exist dan bergerak maju seiring dengan kebutuhan zaman. Termasuk dalam kegiatan operasional penambangan batubara yang ada di PT Beraucoal, saat ini berusaha untuk mengimplementasikan teknologi sebagai tools untuk kendali bahaya yang muncul. Salah satunya adalah penggunaan DMS (Driving Monitoring System) yang bertujuan untuk melakukan pengawasan langsung terhadap prilaku pengopersian unit/kendaraan (aktifitas operator di dalam kabin dan kondisi di luar kabin) untuk mencegah kecelakaan yang disebabkan oleh un safe act dari operator saat mengoperasikan unit. Dalam tahap awal, implementasi DMS diterapkan batu hanya pada kegiatan hauling coal, karena selain tingkat incident pada kegiatan pengoperasian unit di lokasi ini cukup tinggi, lokasi ini juga dari segi infrastruktur lebih menudukung, yaitu berupa keberadaan jaringan cellular sebagai salah satu elemn untuk dapat menjalankan DMS secara ideal dan maksimal. Fokus kendali DMS pada tiga Tindakan Tidak Aman yang diketahui sebagai penyebab terbesar kecelakaan pada kegiatan pengoperasian unit di jalan hauling, yaitu: 1. Prilaku berkendara operator (distraction, smoking, phoning, coalision), 2. Fatigue (yawning, head down, closed eyes), 3. Kecepatan Berkendara. Adapun subyek penelitian adalah perusahaan pertambangan yang merupakan mitra kerja PT. Berau Coal, yaitu: PT. PAMA, PT. BUMA, PT. MADHANI, PT. RICOBANA dan PT. MTL. Tujuan: Penelitian ini bertujuan untuk mengetahui implementasi penggunaan driving monitoring system (dms) sebagai kendali bahaya dari aktivitas pengoperasian unit pengangkutan batubara PT. Berau Coal Metode: Penelitian ini adalah kuantitatif deskriptif yaitu dengan menggunakan pendekatan yang disebut dengan analisis data sekunder. Hasil: Dari data yang dikumpulkan, didapat bahwa implementasi DMS telah memberikan dampak terhadap penurunan jumlah incident pada aktifitas pengoperasian unit di jalan hauling, dengan total penurunan incident rata-rata dalam dua tahun setelah implementasi DMS yaitu sebesar 77%dari total rata-rata incident pada kegiatan pengoperasian unit di jalan jauling selama dua tahun sebelum implementasi DMS. Kesimpulan: Penelitian ini menyimpulkan bahwa upaya implementasi teknologi dalam kegiatan operasional pertambangan di PT. Berau Coal terus dilakukan. Salah satu yang dijalankan saat ini adalah implementasi Driving Monitoring System (DMS), yang berfungsi untuk mengcapture atau menangkap Tindakan Tidak Aman yang dilakukan oleh operator saat mengoperasikan unit
