Abstract

Tandan kosong sawit (TKS) sebagai salah satu limbah padat hasil pengolahan tandan buah segar kelapa sawit, yang memiliki potensi sebagai sumber energi alternatif yaitu sebagai briket biomasa, dengan karakteristik memiliki energi panas 20.093 kg/kJ dan energi kalor sebesar 5.698 kal/gr.  Dalam pemanfaatannya, briket ini dapat berdampak pada kualitas udara dalam ruangan, salah satunya adalah karena gas SO2 yang diemisikan selama pembakaran briket TKS ini. Tujuan dari penelitian ini adalah menentukan besarnya konsentrasi gas SO2 di ruangan dapur  selama pembakaran briket dan melakukan pengendalian pada kondisi pengukuran yang melebihi Baku Mutu Kualitas Udara Ambien. Pengambilan sampel menggunakan alat impinger pada ruangan yang memiliki ventilasi sebesar 5% dari luas lantai ruangan dapur dan kemudian sampel dianalisis dengan menggunakan AAS. Hasil pengukuran diketahui besarnya konsentrasi gas SO2 sebesar 0,16 ppm yang melebihi baku mutu dari PerMen Kes 1077/2011 (0.1 ppm), sehingga perlu dilakukan pengendalian untuk mengurangi emisi yang dihasilkan. Pengendalian yang dilakukan adalah mengatur bukaan ventilasi yaitu pada ventilasi 10% (sesuai standar penyehatan ruangan dari PerMen Kes 1077 tahun 2011) dan pada ventilasi 15%. Diperoleh hasil pada ventilasi 10% sebesar 0,106 ppm SO2 dan pada ventilasi 15% terukur 0,09 ppm SO2.. Berdasarkan hasil ini dapat dinyatakan bahwa pembakaran briket tandan kosong sawit dengan kondisi pembakaran pada bukaan ventilasi 15%, aman digunakan sebagai bahan bakar alternatif dalam skala rumah tangga.

Abstract

The habit of littering is carried out in almost all circles of society, not only the poor, even those with higher education do it. Organic waste and plastic waste are the largest waste generated by households. Processing organic waste into compost and utilizing plastic waste into ecobricks are service activities that have been carried out at Putri Tujuh II Housing Estate, Pekanbaru. This service activity aims to provide understanding and application to residents in managing household waste, so it is hoped that there will be awareness of the importance of waste processing in reducing waste generation in Final Disposal Sites (TPA). The method used is socialization, field practice which is continuously accompanied by the implementing team until the end of the service period. The result of this activity is an increase in public knowledge about processing waste into compost and ecobricks that can be used at home, but there is a decrease in the level of awareness at the end of the activity. This is because residents are no longer assisted in carrying out waste processing activities, so it can be concluded that continuous team assistance is needed until there is a commercial container to accommodate the results of waste processing carried out by residents

Abstract

Produksi minyak sawit yang tinggi berbanding lurus dengan produksi limbahnya. Lumpur kelapa sawit merupakan larutan buangan yang dihasilkan selama prosespemerasan dan ekstraksi minyak.Limbah lumpur kelapa sawit disamping sebagaisumber hara makro dan mikro yang penting bagi tanaman, juga sebagai sumberbahan organik dan berperan pada perbaikan sifat fisik dan kima tanah. Limbahpadat lainnya yang belum dimanfaatkan secara maksimal adalah serat buahkelapa sawit yang juga mengandung unsur hara. Dari kedua potensi limbahpadat kelapa sawit menunjukkan bahwa sangat perlu dilakukan pengolahankhususnya pada limbah lumpur dan serat buah dimana berdasarkan hasil analisalaboratorium mengandung unsur hara yang baik untuk dikonversi menjadi pupukkompos. Mikroorganisme lokal (MOL) adalah mikroorganisme yangdimanfaatkan sebagai starter atau aktivator dalam pembuatan pupuk organikpadat maupun pupuk cair. Bahan utama MOL terdiri dari beberapa komponenyaitu karbohidrat, glukosa, dan sumber mikroorganisme. Tujuan penelitian iniadalah mengetahui kemampuan MOL sebagai aktivator dalam prosespengomposan limbah lumpur dan serat buah kelapa sawit yang disterilkan dantidak disterilkan. Dari hasil penelitian dapat ditarik kesimpulan bahwamikroorganisme pada MOL yang berperan sebagai pendegradasi pada prosespengomposan lumpur dan serat buah kelapa sawit. Hal ini berdasarkan hasilanalisa proses fermentasi tapai singkong menjadi MOL dimana jumlahmikroorganisme pada hari pertama sebesar 403,45mg/l dan pada hari kelimajumlah mikroba meningkat menjadi 456,10 mg/l. Selain itu dapat dilihat jugabahwa bahan baku yang disterilkan untuk parameter kualitas kompos antara lain: N, P, K, C, C/N,Mg, Ca, temperatur, pH, dan kadar air, mempunyai nilai yangmendekati SNI berbanding bahan baku yang tidak steril. Penggunaan MOLsebagai sumber mikroorganisme dalam proses pengomposan dapat dijadikanalternatif sebagai bioaktivator yang ekonomis dan ramah lingkungan.
