<p><em>Ocimum gratissimum</em> L. atau kemangi hutan merupakan salah satu jenis tanaman yang banyak dimanfaatkan dalam bidang pengobatan tradisional. Biji dari tanaman kemangi hutan diduga mengandung senyawa aktif antioksidan berupa skualena yang banyak digunakan dalam industri farmasi. Sumber utama senyawa skualena adalah minyak hati ikan hiu, kenyataan ini memperkuat alasan perburuan ikan hiu semakin marak.

Hasil penelitian menunjukkan bahwa rendemen minyak biji kemangi hutan setelah pemurnian diperoleh sebesar 5,106 ± 0,10%, berwarna kuning pucat berbau khas kemangi hutan, kadar air minyak 0,06%; massa jenis minyak 0,84 g/ml; bilangan asam 0,416 ± 0 mg KOH/g minyak; bilangan peroksida 0,028 ± 0 meq O₂/g minyak; dan bilangan penyabunan 219,648 ± 2,608 mg KOH/g. Sifat fisikokimia tersebut telah memenuhi kriteria SNI. Hasil analisis GC-MS menunjukkan bahwa minyak biji kemangi hutan didominasi oleh  empat komponen utama yaitu skualena (58,85%), asam propanedioat (16,69%),  asam palmitat (14,91%), dan metil heksanoat (9,55%). Pemurnian minyak biji kemangi hutan meningkatkan kandungan skualena dari 1,07% menjadi 58,85%. </p><p><strong><span class="hps"><span style="font-size: 8.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'MS Mincho'; mso-ansi-language: IN; mso-fareast-language: EN-US; mso-bidi-language: AR-SA;" lang="IN">The Effect of Purification on The Quality and Content of Forest Basil Seed Oil (<em>Ocimum gratissimum</em> L.). </span></span></strong><span class="hps"><em><span style="font-size: 8.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'MS Mincho'; mso-ansi-language: IN; mso-fareast-language: EN-US; mso-bidi-language: AR-SA; mso-bidi-font-weight: bold;" lang="IN">O. gratissimum</span></em><span style="font-size: 8.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'MS Mincho'; mso-ansi-language: IN; mso-fareast-language: EN-US; mso-bidi-language: AR-SA; mso-bidi-font-weight: bold;" lang="IN"> L. or </span><span style="font-size: 8.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'MS Mincho'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA; mso-bidi-font-weight: bold;" lang="EN-US">f</span><span style="font-size: 8.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'MS Mincho'; mso-ansi-language: IN; mso-fareast-language: EN-US; mso-bidi-language: AR-SA; mso-bidi-font-weight: bold;" lang="IN">orest </span><span style="font-size: 8.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'MS Mincho'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA; mso-bidi-font-weight: bold;" lang="EN-US">b</span><span style="font-size: 8.5pt; font-family: 'Times New Roman',serif; mso-fareast-font-family: 'MS Mincho'; mso-ansi-language: IN; mso-fareast-language: EN-US; mso-bidi-language: AR-SA; mso-bidi-font-weight: bold;" lang="IN">asil is a plant that is widely used in traditional medicine.

This Community Service activity is aimed at improving the quality of teaching and learning of Kalkurmo Village Elementary School children, Beringin District, Semarang Regency in the fields of Science and Mathematics. Kalikurmo Village has human resources who have low educational backgrounds, so that its residents have minimal insight and are less developed. This caused us to be moved in providing counseling to the residents of Kalikurmo Village, which if it could help add to their insight and knowledge. Activities carried out in the form of assisting classroom teaching and tutoring outside class hours. Elementary school student are helped in deepening science and mathematics material by this activity.
