Neem plants (Azadirachta indica) are commonly found in Situbondo Regency, and currently underutilized nimba plants have many benefits, both in agriculture as pesticides and in pharmaceuticals as medicines. The content of the active compound is more commonly found in nimba seeds. The largest active compound that is an insecticide in neem seeds (Azadirachta indica) is azadirachtin. Azadirachtin is a group of terpenoid compounds which are generally non-polar so that the extraction process can use non-polar solvents. In this study using oil as a carrier solvent, it is known that oil is non-polar. This research was conducted with the aim to know the organoleptic test results of neem seed powder (Azadirachta indica) in oil variations. Organoleptic test results showed physical changes of the three oils, clearly visible in the color produced after treatment. The results of the three samples showed that the color was not clear (turbid). The aroma produced from each oil is not rancid and the pH measurement shows an increase from 5 to 6.   Keywords: Azadirachta Indica Seed, Oil, Organoleptic Test ABSTRAK                   Tanaman nimba (Azadirachta indica) banyak ditemukan di Kabupaten Situbondo, dan pada saat ini kurang dimanfaatkan Tanaman nimba memiliki banyak manfaat, baik dalam bidang pertanian yaitu sebagai pestisida maupun dalam bidang farmasi yaitu sebagai obat-obatan. Kandungan senyawa aktif insektisida lebih banyak ditemukan dalam biji nimba. Senyawa aktif terbesar yang bersifat insektisida dalam biji nimba (Azadirachta indica) yaitu azadirachtin. Azadirachtin merupakan golongan senyawa terpenoid yang umumya bersifat non polar sehingga proses ekstraksinya dapat menggunkaan pelarut non polar. Pada penelitian ini menggunakan minyak sebagai pelarut pembawa, telah diketahui bahwa minyak bersifat non polar. Penelitian ini dilakukan dengan tujuan untuk mengatahui hasil uji organoleptik serbuk  biji nimba (Azadirachta indica) dalam variasi minyak. Hasil uji organoleptik menunjukkan perubahan fisik dari ketiga minyak, terlihat jelas pada warna yang dihasilkan setelah perlakuan. Hasil dari ketiga sampel menunjukkan warna tidak jernih (keruh). Aroma yang dihasilkan dari masing-masing minyak yaitu tidak tengik serta pada pengukuran pH menunjukkan kenaikan dari 5 menjadi 6.   Kata Kunci: Biji  Azadirachta Indica, Minyak, Uji Organoleptik

Degumming Process

In this paper, the extraction process of flavonoids from hemp fibers was studied. Response surface methodology (RSM) analysis of the extraction parameters indicated that optimized results would be ethanol concentration 76 vol.%, bath ratio 1:50, and reaction time 139 min; therefore, an optimal extraction rate of flavonoids of 0.2275% can be obtained. The chemical structure, surface morphology and element composition of flavonoid extracts were analyzed. The test results indicated that hemp extract contains flavonoids, which can be used to extract flavonoids from hemp fiber, so as to comprehensively develop hemp fiber and reduce the discharge of waste liquid in the traditional degumming process.

Objective: This study was focused on to compare the antimicrobial activity of methanolic leaf extracts of tulsi and neem.Methods: We have chosen tulsi (Ocimum sanctum) and neem (Azadirachta indica) to compare their antimicrobial activity toward Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria. Phytochemical extracts have been made by the use of methanol as solvent and dried leaf powder by the cold maceration extraction process. Phytochemical analysis for some secondary metabolites has been done using standard protocols. Nutrient agar plates were inoculated with the above-mentioned microorganisms by spreading bacterial inoculum on the surface of the media. Wells (6 mm in diameter) were punched in the agar. The phytochemical extracts of neem and tulsi were allowed to diffuse into the medium, and after incubation of 24 h at 37°C, the zones of inhibition were observed.Results: Statistical analysis showed that tulsi was more effective toward S. aureus while neem was more effective toward E. coli. Minimum inhibitory concentration (MIC) of tulsi for both the microorganisms was 0.4 g/ml, and the MIC of neem for both the microorganisms was 0.2 g/ml. When both the tulsi and neem extract were mixed with each other for every concentration at equal volume, they have shown better effects in comparison to individual neem or tulsi extract and also the MIC got reduced to 0.2 g/ml for both the bacteria.Conclusions: Leaf extracts of both the A. indica and O. sanctum have shown antimicrobial activity against E. coli and S. aureus. A. indica has higher antimicrobial activity against S. aureus, whereas the O. sanctum was found to be more effective against E. coli (indicated by the zone of inhibition). When both the extracts were mixed with each other, they have shown a better effect toward both bacteria.
