Abstract

This study aimed to evaluate the aromatic characteristic of patchouli essential oil (Pogostemon cablin Benth.) by near‐infrared spectroscopy combined with chemometric treatments. The study used 84 oil samples collected from around Indonesia, namely in Konawe, Kolaka, Bogor, Garut, Aceh, Jambi, and Masamba. Several pretreatments were used to process the spectral data, together with the application of partial least squares. The spectrum wavelength applied was between 1000 and 2500 nm. The spectra data were separated to develop two models based on their physical and chemical properties (Bogor, Garut, Konawe, and Kolaka in the first model; Aceh, Jambi, and Masamba in the second one). Liquid chromatography‐mass spectrometry (LC‐MS) was used as a reference method. Patchouli alcohol was established as the main chemical compound of this aromatic oil. The best calibration for the first model was that with mean center normalization as a data pretreatment, while for the second model, it was the one using the second derivative. Both models had a correlation coefficient higher than 0.90 and a coefficient of variation lower than 2.98%. In conclusion, near‐infrared spectroscopy can be employed as an accurate tool to determine the characteristic of patchouli oil.

Abstract

Background: The palm oil industry strives to implement sustainable development, maintaining the environmental quality. However, the palm oil industry has problems processing liquid waste, often known as palm oil mill effluent (POME), since it could pollute the environment. This waste also requires a large costs to be processed. On the other hand, there is potential economic value from liquid waste to be processed into several products, namely biogas, organic fertilizer, and refining value-added compounds. Currently, POME waste processing innovation could be conducted by applying plasma nanobubble (PNB) technology. This creates opportunities for a business that is engaged in developing this technology.Purpose: The aim of this research is to analyse the business model of the Plasma Nano Bubble (PNB) technology development business for the palm oil industry. Design/methodology/approach: This research uses the Business Model Canvas (BMC) to map the business processes of the Plasma Nano Bubble (PNB) technology development.Findings/Result: This study indicate that the most prominent attribute exhibited by PNB technological enterprises is their value offer, which is demonstrated by their ability to deliver efficient processing time and cost effectiveness, resource efficiency, adherence to government regulations, and the establishment of strategic collaborations with external entities. Meanwhile, the weakest element is customer relations, as only long-term relationships, and the provision of intensive training for PNB technology resellers were found in this aspect. Several indicators were proposed to improve the business model of PNB's technology, namely key partnership, the key activity, value proposition, and customer relationship.Conclusion: This research gives an important contribution related to the environmental benefits of implementing this business. The continuous development for this technology needs to be implemented to process POME waste effectively and efficiently.Originality/value (State of the art): The state of the art of this research is the development of business models for environmentally friendly products in the palm oil sector, which is currently rarely conducted, in this case the study of PNB technology products.
