Difference and variation of leaves shape is usually used as primary identifier of the plant species. But some plants may have a similar leaf shape and thus require another more accurate identifier. This study applied principal component analysis (PCA) methods for identifying tropical plant species from the shape of the leaves. This method simplified the observed variables by reducing the dimensions of the information that is stored as much as 75%, so it did not eliminate important information and can save the data processing time. There were 100 images of leaves taken from several sides of the leaf in JPEG format with which the shape of leaves were look similar, like citrus (Citrus aurantifolia), durian (Durio zibethinus), guava (Psidium guajava), mango (Mangifera indica), jackfruit (Artocarpus heterophyllus), avocado (Persea americana), rambutan (Nephelium lappaceum), sapodilla (Manilkara zapota), red betel (Piper crocatum) and soursop (Annona muricata). Identification of those 10 kind plant leaves produced 97% accuracy rate. Measurement systems were designed using the K-fold Cross Validation with k = 10, the results of experiments shown omission error occurs on the leaves of guava, jackfruit and red betel while twice commission error were found on the leaves sapodilla and once on citrus leaves.

Indonesia's biomass energy potential is estimated at around 49,810 MW and is very adequate for the development go renewable energy. An example of a biomass conversion technique is pyrolysis which converts biomass into bio-oil. The optimum temperature for the pyrolysis process is 300-600 0C. Parameters that affect the pyrolysis process such as pretreatment of the material, moisture content and particle size of the material, the composition of biomass compounds, the effect of temperature, heating rate, gas flow rate, type of pyrolysis, and pyrolysis reactor. This is a thermochemical technique in which biomass waste is converted into solid fuel (char), producer gas (syngas), and liquid (bio-oil) without oxygen in a reactor. This article contains a comprehensive review of biomass conversion techniques to bio-oil using the solar energy-based fast pyrolysis method. Furthermore, the exposure used was based on the publication source, year, origin country, research methodology, and focus area. Most research has been empirical and mainly focused on fast pyrolysis and its influencing factors. There are several studies, information, and research recommendations described in this article.

Proper processing of coconut shell charcoal can be highly economically and environmentally valuable. The two most common uses of coconut shell charcoal are activated carbon and briquettes, obtained through carbonization. However, traditional carbonization methods involving kilns can produce excessive smoke, polluting the environment and disrupting human activities. A carbonization kiln that produces less smoke is required to address this issue. In this study, a kiln made from a steel drum with a sealer belt was fabricated to trap burning smoke inside the kiln. The results showed that adding this belt effectively reduced the smoke produced, making it more eco-friendly. Regarding charcoal production efficiency, different weigh coconut shells were burnt to produce charcoal. The result showed that burning 25 kg of coconut shell was optimal, producing a 48% charcoal content.
