Abstract

ABSTRACTSeveral alternative waste management innovations from oil palm mills with a capacity of 30 tons / year have been evaluated. These waste innovations are based on the most optimal renewable energy yield produced by oil palm mills, ie biogas, compost and pellets. The evaluation stage begins by collecting data from the operations of the common palm oil factories that is used as the data base-line. Furthermore, preliminary data is compared with the data of waste management innovation which is grouped into 3 (three) activities: (1) compost production from empty bunches, (2) biogas production from liquid waste treatment and (3) pellet production. The comparative results state that the plant's ability to process 1 ton of fresh fruit bunches can produce alternative renewable energy products either 207 kg of compost or 125 kWh of electricity or 125 kg pellets. This paper aims to evaluate the performance of palm oil mills in renewable energy production that is the most optimal in generating the largest profit margin. The results showed that based on the maximum profit potential obtained from each process of waste management, the percentage of the processed waste is about 19.8; 45.5 and 34.6% for the respective compost, biogas and pellet production. The processed waste will earn profit from renewable energy products of compost, biogas and pellet of as many as 6.1; 31.3 and 54.47 US$ / ton respectively. The overall waste treatment requires operating cost of 2.34 US $/ton and will result in a total profit of 91.89 US $ / ton.Keywords: waste, palm oil mill, renewable energy, performance evaluationABSTRAKBeberapa alternatif inovasi pengelolaan limbah dari pabrik kelapa sawit dengan kapasitas 30 ton/tahun telah dievaluasi.

Abstract

ABSTRACTThe ability of tapioca to act as natural coagulants (biocoagulants) was tested using artificial water. As turbidity was added as kaolin. This research aimed to determine the compounds and or groups that act as natural coagulant and to describe the mechanism of flocculation: extraction which yields tapioca extract and ion exchange which yields ionic tapioca. Coagulation process was performed at three different initial turbidities, i.e. 50 NTU (low turbidities), 150 NTU (middle turbidities) and 300 NTU (high initial turbidites). At the same condition (coagulant dose 20 ppmv, pH 5), ionic tapioca yield better turbidity removal compared tapioca extract i.e 11.2% at low initial turbidites; 2.4% at middle initial turbidities and 12.8% at high initial turbidities. FTIR analysis  showed that tapioca extract and ionic tapioca contained of carboxyl, hydroxyl and amides groups which  can act as active components on coagulation process. The presence of those groups caused positive and negative charges (amphoter). Coagulation process ran efficiently at pH 5 because the isoelectric point is obtained at that condition.Keyword : bio coagulants, coagulation,  coagulant agents, ionic tapioca, tapioca extract,ABSTRAK Kemampuan tepung tapioka sebagai koagulan alami (biokoagulan) telah diuji dengan menggunakan limbah artifisial dari kaolin. Penelitian ini bertujuan untuk menentukan senyawa atau gugus yang berperan sebagai biokoagulan dan menjelaskan mekanisme flokulasi yang terjadi. Perlakuan awal tapioca sebelum digunakan sebagai koagulan adalah ekstraksi yang menghasilkan ekstrak tapioka  dan pertukaran ion  yang menghasilkan tapioka ionik. Proses koagulasi dilakukan pada 3 macam kekeruhan awal yaitu 50 NTU (kekeruhan rendah), 150 NTU (kekeruhan sedang) dan 300 NTU (kekeruhan tinggi). Pada kondisi operasi yang sama (dosis 20 ppmv dan pH 5), tapioka ionik memberikan efisiensi penurunan kekeruhan yang lebih tinggi, yaitu sebesar 11,0% pada kekeruhan awal 50 NTU; 2,4% pada kekeruhan awal 150 NTU dan 12,8% pada kekeruhan awal 300 NTU. Hasil analisa FTIR menunjukkan bahwa ekstrak tapioka dan tapioka ionik mempunyai gugus karboksil (-OH), gugus karboksil (-COOH) dan gugus amida (-CONH2). Keberadaan ketiga gugus tersebut menyebabkan biokoagulan ini memiliki muatan positif dan negatif sekaligus (amfoter). Proses koagulasi berjalan dengan efisien pada pH 5 karena titik isoelektrik diperoleh pada pH tersebut. Kata kunci : biokoagulan, koagulasi, agen koagulan, ekstrak tapioka, tapioka ionik

Abstract

ABSTRACTThe phosphorus loading from aquaculture activity as a product of floating net cages (KJA) in Cirata Reservoir have exceeded the carrying capacity of the aquatic ecology. This results in a decrease in water quality which is characterized by uncontrolled phytoplankton growth. The stocking of fish is one of the ways used in the improvement of the aquatic environment resulting eutrophication. Phosphorus which is wasted from cultivation activity will be utilized by phytoplankton for its growth. The phytoplankton can be utilized by planktivorous fish as its natural feed. One type of fish that can be used for stocking is a planktivora fish as milkfish (Chanos chanos). The purpose of this study was to estimate the load of phosphorus and calculate the number of milkfish seeds which are planktivorous fish that can be stocked with the aim of reducing phosphorus waste from aquaculture activities in Cirata Reservoir, West Java. The result showed that P load from cultivation activity at Cirata Reservoir was 1,206 tons/year. The concentration of chlorophyll-a and the primary productivity produced by the P load from the cultivation activities were 28.6 mg/m3 and 364.6 gC/m2/year respectively. The number of milkfish seeds that can be stocked as an effort to utilize the load of phosphorus as much as 1.8 million/year. The P load can be reduced based on estimation of harvested fish biomass and phosphor requirement for milkfish of 11.52 ton/year.Keywords: Cirata Reservoir, phosphorus loading, stocking, milkfishABSTRAKBeban masukkan fosfor (P) dari kegiatan budidaya ikan dalam keramba jaring (KJA) dari pakan yang terbuang dan sisa metabolisme ikan di Waduk Cirata telah melebihi daya dukung ekologi perairan. Hal ini berdampak pada penurunan kualitas perairan yang ditandai oleh pertumbuhan fitoplankton yang tidak terkendali. Penebaran ikan merupakan salah satu cara yang digunakan dalam perbaikan lingkungan perairan akibat dari eutrofikasi. Fosfor di perairan dimanfaatkan oleh fitoplankton untuk pertumbuhannya. Fitoplankton tersebut dapat dimanfaatkan oleh ikan planktivora sebagai pakan alaminya.Salah satu jenis ikan yang dapat ditebar (stocking) adalah ikan planktivora yaitu ikan bandeng (Chanos chanos). Tujuan penelitian ini adalah untuk mengestimasi beban masukkan fosfor serta menghitung jumlah benih ikan bandeng yang dapat ditebar dengan tujuan pengurangan limbah fosfor dari kegiatan budidaya di Waduk Cirata, Jawa Barat. Hasil penelitian menunjukkan beban P yang berasal dari kegiatan budidaya di Waduk Cirata sebesar 1.206 ton/tahun. Konsentrasi klorofil-a dan produktivitas primer yang dihasilkan oleh beban P dari kegiatan budidaya masing-masing sebesar 28,6 mg/m3 dan 364,6 gC/m2/tahun. Jumlah benih ikan bandeng yang dapat ditebar sebagai upaya pemanfaatan beban masukkan fosfor sebanyak 1,8 juta ekor/tahun. Beban P yang mampu dikurangi berdasarkan estimasi biomassa ikan yang dipanen dan kebutuhan fosfor untuk ikan bandeng sebesar ton 11,52 ton/tahun.Kata kunci: Waduk Cirata, beban fosfor, penebaran, bandeng
