ABSTRAKIndonesia adalah negara pengekspor CPO (crude palm oil) terbesar kedua di dunia. Produk sampingan dari prosesing CPO yang berupa limbah padat yaitu cangkang, serat dan tandan kosong sawit (TKS) ini bisa dijadikan alternatif sumber energi terbarukan. Gasifikasi adalah teknologi yang layak untuk konversi limbah padat karena memenuhi standar emisi dan memberikan efek minimasi penggunaan lahan TPA. Penelitian ini bertujuan untuk memahami potensi konversi limbah padat kelapa sawit menjadi bahan bakar gas (H2 dan CO) dengan proses gasifikasi. Penelitian dilakukan dengan eksperimen thermogravimetri terhadap 3 jenis limbah padat kelapa sawit untuk menganalisis karakteristik gasifikasi limbah padat tersebut. Untuk memahami komposisi bahan bakar gas yang dihasilkan, dilakukan simulasi proses gasifikasi dengan menggunakan software kesetimbangan kimia HSC Chemistry 5.1. Hasil thermogravimetri menunjukkan bahwa kandungan fix carbon (FC) dan fuel ratio dalam cangkang lebih besar dari serat dan tandan kosong sawit (TKS). Kandungan volatile matter (VM) TKS lebih besar dari serat dan cangkang. Hal ini mengakibatkan produksi gas CO cangkang kelapa sawit lebih besar dibanding serat dan TKS, sebaliknya produksi gas H2 dari TKS lebih tinggi dibandingkan cangkang dan serat. Berdasarkan hasil perhitungan kesetimbangan kimia, dapat disusun skema reaksi gasifikasi limbah padat kelapa sawit sebagai berikut:CxHy + aCO2 ? (x+a)CO + y/2H2.Kata Kunci: limbah padat CPO, gasifikasi, bahan bakar gas, volatile matter (VM), fix carbon (FC) ABSTRACTIndonesia is the second largest CPO (crude palm oil) exporting countries in the world. CPO processing generates solid wastes including shell, fiber and empty fruit bunche (EFBs), which can be used as alternative sources of renewable energy. Gasification is feasible technology to convert solid waste because it can meet the emission standard and minimize landfill application. This paper studies the potency of palm solid waste conversion to fuel gases (H2 and CO) through gasification proces. This research was carried out by thermogravimetric experiments on three kinds of palm solid waste to understand their gasification characteristics. Chemical equilibrium calculations of gasification process was carried out by using HSC Chemistry 5.1 software to understand the fuel gas composition. Thermogravimetric analysis suggested that the fix carbon (FC) content and fuel ratio of shell was higher than those of fiber and EFBs. Whereas, volatile matter (VM) content of EFBs was higher than that of fiber and shell. It caused CO production of shell was higher than that of fiber and EFBs, otherwise, the H2 production of EFBs was higher than that of shell and fiber. Based on chemical equilibrium calculation, gasification reaction scheme of palm solid waste can be arranged as follows: CxHy + aCO2 ? (x+a)CO + y/2H2.Keywords: CPO solid waste, gasification, fuel gas, volatile matter (VM), fix carbon (FC).

AbstrakMinyak kelapa sawit adalah minyak nabati yang paling banyak dikonsumsi dunia. Setengah dari produksinya berasal dari Indonesia, walaupun perluasannya telah dikritik dari sudut pandang lingkungan. Pengurangan dampak lingkungan perkebunan melalui praktik pengelolaan limbah yang lebih baik sangat penting untuk mencapai produksi yang lebih bersih. Dalam konteks ini, penelitian difokuskan pada pengomposan, praktik yang semakin banyak diterapkan di agroindustri. Penelitian bertujuan untuk menguji pengomposan produk samping pabrik kelapa sawit yaitu tandan kosong kelapa sawit (TKKS) dan limbah cair pabrik kelapa sawit (LCPKS), pada rasio LCPKS/TKKSdan frekuensi pembalikan yang berbeda. Setelah 60 hari, kompos masih dalam fase mesofilik dan tidak dapat dianggap sebagai kompos matang karena rasio C/N dan suhu yang tinggi. Penurunan bobot dan volume yang tinggi telah dicapai masing-masing sebesar 40% dan 60%, serta penguapan air yang signifikan dari LCPKSdan TKKS(60%). Rasio LCPKSterhadap TKKSpada 1 – 1.5 m3/ton adalah optimal untuk mencapai kelembaban (65-70%), ruang udara bebas (>50%) dan pemulihan nutrisi, juga menunjukkan bahwa dalam kondisi percobaan ini proses pengomposan tidak dapat menggunakan semua LCPKSyang diproduksi oleh pabrik (3m3/ton TKKS). Tingkat pemulihan nutrisi mendekati 100% untuk fosfor, kalium dan magnesium, sedangkan untuk nitrogen terjadikehilangan sekitar 30-35%. Pengomposan dengan platform beton dan beratap, tidak melakukan penyemprotan pada tumpukan secara berlebihan, dan mendaur ulang semua limbah cair merupakan hal penting untuk mencapai efisiensi pemulihan nutrisi yang tinggi dan untuk mengontrol kualitas kompos akhir.[Kata kunci:pengomposan, tandan kosong, pemulihan nutrisi, kelapa sawit, limbah cair pabrik kelapa sawit, keberlanjutan]AbstractPalm oil is the most consumed edible oil in the world. Roughly half of the production originates from Indonesia, where the expansion of the crop has been criticized from an environmental perspective. Reducing the environmental impact of plantations through better waste management practices is critical to achieve cleaner production. In this context, our study was focused on composting, a practice increasingly adopted among agro-industries. Our trial was designed to test co-composting of the main palm oil mill by-products – empty fruit bunches (EFB) and palm oil mill effluent (POME) – under different POME/EFB ratios and turning frequencies. After 60 days the compost was still in a mesophilic phase and could not be considered as mature compost due to high C/N ratio and temperature. High weight and volume reduction were achieved (40% and 60% respectively), as well as significant water evaporation from the POME and EFB (60%). We found that a POME to EFB ratio of 1 to 1.5 m3/ton was optimal for moisture (65-70%), free air space (>50%) and nutrient recovery, showing that in our experimental conditions the composting process could not use all the POME produced by the mill (3m3/ton of EFB). The nutrient recovery rate was close to 100% for phosphorus, potassium and magnesium. For nitrogen we observed 30-35% of losses. Composting on a concrete platform with a roof, not over-spraying the piles and recycling all the leachates are critical points to achieve high nutrient recovery efficiency and to control final compost quality.[Keywords:composting, empty fruit bunch, nutrient recovery, oil palm, palm oil mill effluent, sustainability]

Derivative Products

Indonesia is one of the largest palm oil producer in world. The products of palm oil derivative diverse, ranging from cooking oil, margarine, soap, and biodiesel. So far, Indonesia is more likely to export Crude Palm Oil (CPO) to various countries. But on the other hand, Indonesia need to reduce the burden imports of some palm oil derivative products such as cooking oil, biodiesel, and soap. It is therefore, we need a breakthrough to improve the production of crude palm oil and its derivative products so that we can increase the availability of the derivative products. Based on this existing condition, we need an approach that can analyze the use condition of the palm oil derivative products and improve the palm oil use of derivative products in the future. Therefore, in this research, we will develop a model that can analyze and develop some policy scenarios to improve the utilization of palm oil derivative products. The method used for the model development is system dynamics, based on the ability to accommodate the internal and external factors that affect the production of palm oil derivative products.From the model scenarios we obtained that by sorting the fruits harvested, so that the levels of Oil Extraction Rate is at 22.1%, it can increase the stock of CPO by 11%. By utilizing 50% of CPO for the cooking oil production will meet the needs of the national cooking oil demand, with a ratio of 1.5 fulfillment began in 2010. If we utilize 35% of CPO to be processed as stearin, and use 10% of stearin in the soap contain, it will fulfill the need of domestic soap until 2015.  By utilizing the empty fruit bunches waste as raw material for biodiesel, there will be additional biodiesel production of around 920,479 kilolitres in 2019. Meanwhile, the use of 1% of CPO production to create biodiesel, it will make biodiesel production reaches 31,173 kilolitres in 2019.  From these efforts, there will be 951,652 kilolitres biodiesel production in 2019.

The concept of biorefinery offers the utilization of biomass, in particular agricultural waste, to be converted intoenergy, chemicals, materials, and food. In 2013 Indonesia produced about 27.4 thousand tons of crude palm oil(CPO) which corresponds to approximately 30 thousand tons of oil palm empty fruit bunches (EFB), the biomasswaste from palm oil industries. The huge availability of EFB in Indonesia may serve as a good starting point toimplement the concept of biorefinery. EFB mainly comprises of cellulose, hemicellulose and lignin. Thecellulosic components of EFB have been thoroughly studied, i.e. for the production of bioethanol. Thehemicellulosic component of EFB, which is a polymeric substance that comprises mainly of xylose, has beenbarely explored. This paper reviewed the potential utilization of hemicellulosic component of EFB to beconverted to xylitol, the 5-carbon-sugar-alcohol which is low calorie, low Glycemic Index, and anti-cariogenic.The pretreatment and hydrolysis of EFB and the following fermentation of EFB hydrolysate to xylitol will bediscussed further.
