Abstrak. Penelitian ini bertujuan untuk melakukan pengujian pada alat pencacah tandan kosong kelapa sawit (Elaeis guineensis Jacq) tipe reel dengan menggunakan 3 variasi kecepatan putaran roll pengepress yaitu 40, 60, dan 80 rpm. Alat pencacah ini menggunakan system transmisi sabuk pulley, dengan menggunakan motor penggerak mesin diesel dengan daya 6,5 HP, dengan bahan tandan kosong sawit (TKS) sebanyak 3 kali pengujian untuk setiap satu pengujian kecepatan dengan berat awal setiap pengujian ±3,010 kg, dengan menggunakan roll pengepress sebelum melakukan proses pencacahan yang berfungsi untuk mencengkram dan sebagai pengumpan serta menekan tandan kosong kelapa sawit. Serta hasil pengujian yaitu hasil cacahan kehilangan hasil cacahan, dan keseragaman hasil cacahan. Dengan adanya pengujian kecepatan roll pengepress terhadap mesin pencacah ini akan berpengaruh terhadap hasil cacahan dan ukuran hasil cacahan. Hasil cacahan yang dihasilkan dengan adanya penambahan roll pengepress dan menggunakan beberapa variasi kecepatan putaran roll pengepress kemudian dilakukan pengujian keseragaman hasil dengan menggunakan ayakan yang dibagi menjadi 3 ukuran yaitu untuk hasil cacahan tandan kosong  3 cm yaitu hasil cacahan halus, 3-5 cm yaitu hasil cacahan sedang dan 5 cm yaitu hasil cacahan kasar. Ukuran hasil cacahan dipengaruhi oleh berbagai macam hal, yaitu kecepatan putaran mesin, system pengumpanan, ukuran bahan, dan mata pisau pencacah. Kemudian berbagai macam bentuk dan alur mata pisau pencacah juga dapat mempengaruhi tingkat kehalusan hasil cacahan. Pada kecepatan 40 rpm didapatkan rata-rata hasil cacahan 2.059 kg dengan rata-rata cacahan kasar 59.58%. Pada kecepatan 60 rpm didapatkan rata-rata cacahan sedang 17.46%. Pada kecepatan 80 rpm didapatkan rata-rata hasil cacahan halus 32.46%.Performance Test of Roll press At Variations Of Round Speed In The Coconut Oil Palm Blast Counter Appliance (Elaeis Guineensis Jacq)Abstract. This study aims to test the reel type oil palm empty fruit bunches (Elaeis guineensis Jacq) using 3 variations of pressing roll rotation speed, which are 40, 60, and 80 rpm. This chopper uses a belt pulley transmission system, using a diesel engine driven motor with a power of 6.5 HP, with oil palm empty fruit bunches (TKS) as much as 3 tests for each speed test with the initial weight of each test ± 3.010 kg, using roll press before carrying out the enumeration process which the purpose to grab and feed as well as to suppress oil palm empty bunches. As well as the test results which are the chopped results loss the chopped results, and the uniformity of the chopped results. By testing the pressing roll speed on the counter machine it will affect the chopped results and the size of the chopped results. The chopperd results were produced by the addition of a pressing roll and using several variations of the pressing roll rotation speed then the uniformity of the results was tested using a sieve which was divided into 3 sizes which is for the results of 3 cm empty bunches is soft chopped results, 3-5 cm is chopped results medium and 5 cm which is the result of rough chopped. The size of the chopped results is influenced by various things, which are the speed of the engine rotation, feeding system, the size of the material, and the counter blade. Then the various shapes and blades of the enumerator's blades can also affect the level of fineness of the chopped results. At a speed of 40 rpm the average chopped results of 2,059 kg was obtained with an average roughly chopped of 59.58%. At a speed of 60 rpm it was found that the average chopped results was 17.46%. At a speed of 80 rpm, 32.46% of the fine chopped results were obtained.

Oil palm plantations are very extensive in Indonesia which have produced oil palm solid waste in the form of oil palm empty fruit bunches (OPEFB, shells and fibers. Generally, OPEFB is processed into compost but has a constraint that requires a long time of three months. The solution is to provided bioactivators.  This study aims to determine variations in the amount of cellulolytic bioactivators in composting OPEFB that is 0 ml (P1), 50 ml (P2), 75 ml (P3) and 100 ml (P4). Composting is carried out at an incubation laboratory scale for 45 days. The best research results were obtained in P4 treatment with compost quality: N-total of 2.13; C-organic: 35,45 and C/N ratio 16,68 which are in accordance with SNI standards. This cellulotic bioactivator can be developed for the production of TKKS compost on a larger scale.
