Briket diproduksi dengan pemadatan bahan baku di bawah berbagai beban tekan. Bahan baku yang digunakan untuk memproduksi briket berasal dari biomassa pertanian dan limbah rumah tangga tidak berbahaya. Bahan baku semacam ini menawarkan sumber energi alternatif yang berkualitas dan berkelanjutan. Metode penelitian yang digunakan adalah metode pencampuran dual stage dengan menggunakan teknologi hidrolik press untuk pencetakannya. Material yang kami gunakan adalah sekam padi dan sebuk gergaji dengan pebandingan (sekam padi 40%:serbuk gergaji 40%), untuk perekat menggunakan tepung tapioka sebasr 10% dan air 10%. Berdasarkan penelitian yang sudah dilakukan, tujuan penelitian ini adalah melakukan analisis variasi tekanan briket untuk mendapatkan sifat mekanik yang baik (briket tidak mengalami prosentase kehancuran yang tinggi dan tidak banyak menyerap air). Pada penelitian ini akan memperoleh data densitas, ketahanan bentur, ketahanan air dan laju pembakaran briket. Semakin padat tekanan pada briket maka semakin kecil pori pori yang di hasilakn.Semakin kecil ukuran pori pori briket maka ikatan antar partikel akan semakin kuat. Semakin kuat ikatan partikel pada briket maka densitas briket semakin tinggi.Semakin tinggi densitasnya maka semakin kuat briket tidak akan mudah hancur. Pada penelitian ini mendapatkan Nilai hasil pengujian densitas rata-rata sebesar 0,551- 0,770 gram/cm3 yang dimana menjukan semakain padat tekananya semakin bagus nilai densitasnya. Nilai hasil pengujian droptest tekanan rata-rata sebesar 45,15% - 4,67% ya itu semakin padat tekanannya semakin kecil persentase kerusakan pada brikrt. Nilai hasil pengujian ketahanan air sebesara 54,14% - 40,44%. Nilai laju pembakaran sebesar 0,224 - 0,171 gram/menit. Nilai hasil pengujian kadar abu sebesar 6,9015,10%.Variasi tekan mempengaruhi nilai densitas,droptets,laju ketahanan air,laju pembakaran dan kadar abu. Jadi semakin tinggi tekanannya maka semakin bagus pula kualitas briketnya. Maka pada penelitian ini tekan yang paling optimal adalah 110 Psi karena dalam 5 penujian 4 pengujin sudah menenuhi syarat yaitu pengujian densitas,droptets,ketahanan air, laju pembakaran.
