Abstract

There are considerably limited evaluations had dealt with the demand side of the Indonesian B20 biodiesel market. Thus, market research on product performance, product importance, and consumer awareness was performed. This research utilized both qualitative and quantitative methods. In-depth interviews with key informants were summarized in the word cloud form. The outcomes then became the ground for quantitative research. The results of 111 online questionnaires indicated that there was a gap in the level of awareness among respondents in Sumatra to that of outside Sumatra. The male, higher education background, and heavy-user of bio solar cohort were tended to vote a sizeable number in the performance evaluation. Especially for the performance of biodiesel that caused sedimentation on the filter engines (73.08%, 72.35%, and 73.08%). Meanwhile, biodiesel performance that supports the nation's energy security is the most important attribute to be highlighted as the product main entity. The policy implication through multifaceted strategies such as incentive provision for automotive companies that are adaptive to market demand is one of a kind. In the long run, the return to investment from these policies are expected to not only increase the multiplier effects of the oil palm plantation but also national energy security.AbstrakSejauh ini belum ada evaluasi ilmiah yang mempelajari aspek permintaan produk biodiesel Indonesia dari sisi konsumen (pasar), sehingga studi mengenai evaluasi produk dan kesadaran konsumen biodiesel B20 menjadi tujuan dari penelitian ini. Riset pasar ini menggunakan metode kualitatif dan kuantitatif. Temuan dari riset kualitatif dalam bentuk wordcloud menjadi landasan untuk kajian kuantitatif. Hasil deskriptif dan nonparametrik 111 kuesioner secara daring mengindikasikan adanya kesenjangan tingkat kesadaran antara responden berdomisili di Sumatera dan luar Sumatera. Responden berjenis kelamin laki-laki, berlatar pendidikan tinggi, dan dominan menggunakan biosolar sebagai bahan bakarnya cenderung kritis menilai atribut terjadinya endapan pada mesin filter (73,08%; 72,35%; dan 73,08%). Performa biodiesel yang mendukung ketahanan energi bangsa menjadi aspek penting yang harus ditonjolkan sebagai entitas dari produk. Inovasi produk dapat dikembangkan melalui kebijakan multidimensi. Salah satunya dengan intervensi pemerintah melalui pemberian insentif bagi automaker yang adaptif terhadap permintaan pasar. Pada akhirnya, implikasi kebijakan ini diharapkan tidak hanya meningkatkan multiplyer effect dari perkebunan kelapa sawit, tetapi juga ketahanan energi nasional.

Abstract

The technology used to reduce oil loss at output sludge from underflow Continuous Settling Tank (CST) is a sludge separator and 3-phase decanter. In POM A, oil extraction is done manually with an oil loss rate of 0.36 tons/hour or 7.83 m3/day. The resulting oil loss figures indicate that extracting the oil using a sludge separator or 3-phase decanter is necessary. The research method used in this study is the comparison of primary data and secondary data on the working principle, the number of supporting equipment, electrical power requirements, operations, maintenance, investment costs, and waste quality. Primary data used oil content, flow rate, and temperature of CST underflow liquid; oil content and effluent flow rate from the final drab output; the amount of oil quoted and returned to the POM. Secondary data in the form of POM performance reports, waste production reports, and data on the specifications of the sludge separator and 3-phase decanter from producers. The working principle of the sludge separator and 3-phase decanter are particle size, bowl layout, bowl rotation direction, output type, sludge capacity, equipment capacity, and oil loss. The 3-phase decanter has 28 units of processing support equipment, more than the 22 units of sludge separator. The power requirement of the sludge separator is 45-60 kWh with a total of 3 units, and a 3-phase decanter requires an electrical power of 22-55 kWh with a capacity of 1 unit. Operationally there are supporting factors for sludge separator, including temperature, nozzle size, and bowl rotation, while supporting aspects for 3-phase decanter include flow rate and feed composition, centrifugal and differential speeds, depth of clarification zone, and weir liquid discharge opening. Maintenance of sludge separator and 3-phase decanter influenced by diluent water, operation, and damage factors. The range of investment costs in the procurement of sludge separators is IDR 0.863-1.837 billion, while the 3-phase decanter is IDR 3.804-5.825 billion. The quality of the 3-phase decanter waste is better than the sludge separator. These results indicate that the most effective tool for processing CST sludge output is a 3-phase decanter. Comparison of the working principle of 3-phase sludge separator and decanter.
