Termiticide activity of methanol extract of Centella asiatica L. Urban against Coptotermes curvignathus Holmgren was investigated using the no choice test. The chemical components of methanol extract of C. asiatica were identified by GC-MS. The antitermite activity showed that the percentage of termite mortality increased when the concentrations of extract increased. The concentrations of 25% indicated the highest termite mortality which reached 100% on the sixth day. Profiling GC-MS methanol extract of C. asiatica revealed 85 chemical components. Based on MS spectral data, 56 chemical components were identified which were grouped into fatty acids (27.09%), esters (23.73%), hydrocarbons (16.56%), ethers (8.28%), sesquiterpenes (1.61 %), alcohol (1.55 %), aldehydes (3.50%), monoterpenes (1.08%), diterpenes (0.67%), steroids (0.43%), and ketones (0.31 %). Among these, the presence of palmitic acid, patchouli alcohol, and β-caryophyllene may be responsible for its termiticide activity. Other compounds such as triterpenoids, saponins, flavonoids, tannins, steroids, and glycosides that were reported previously not detected by GC-MS in this study, possibly contributing to its activity.

Pada penelitian ini, nanopartikel emas disiapkan melalui pendekatan green synthesis menggunakan ekstrak air bunga tapak kuda (Ipomoea pescaprae L. Sweet). Nanopartikel emas yang dihasilkan dianalisis menggunakan spektrofotometer UV-Vis, Mikroskop Leica, Particle Size Analyzer (PSA), Spektrofotometer Fourier Transform Infra-Red (FTIR) dan X-ray Difractometer (XRD). Hasil pengukuran PSA menunjukkan ukuran partikel terbaik, diperoleh dengan menggunakan perbandingan volume 1 mL larutan HAuCl4 dengan 9 mL ekstrak yang menghasilkan partikel dengan ukuran rata-rata 16,3 nm. Hasil penampakan dengan mikroskop cahaya, memperlihatkan partikel berbentuk bulat. Pergeseran bilangan gelombang pada spektrum infra-merah menunjukkan adanya interaksi antara metabolit sekunder dari ekstrak dengan material emas. Analisis XRD menunjukkan bahwa nanopartikel emas telah dapat dihasilkan dari kondisi reaksi ini.

Cerium (IV) oxide or ceria (CeO2) was fabricated by heating an aqueous extract of Garcinia mangostana and cerium (III) nitrate in hydrothermal autoclave reactor at 200 °C for 3 hours, followed by calcination at 600 °C for 5 hours. The powder X-ray diffraction (XRD) pattern of the precipitate from cerium(III) nitrate under hydrothermal reaction conditions shows no clear XRD peaks, indicating its amorphous nature. In contrast, the products from the calcinated samples exhibit XRD peaks, which correspond to cubic fluorite structure with an average crystal size of 7.55 nm. The elemental mapping using the energy-dispersive X-ray (EDX) analysis reveals the main elements present were cerium and oxygen, with minor impurities in low amounts. The presence of Garcinia mangostana extract is predicted to be the key component and fuel source to obtain CeO2 particles with narrow crystal size.

Pacar air (Impatiens balsamina L.) plant belongs to the Balsaminaceae family and is used as an indigenous medicine in Asia for fingernail inflammation, fractures, and rheumatism treatments. Moreover, the antipruritic, antianaphylactic, antifungal, antibacterial, and antitumor activities of some compounds, especially phenolics and quinones from this plant have been studied extensively. Therefore, this study aims to determine the antifungal activity of Pacar air leaves (Impatiens balsamina L.) methanol extract against Rhizopus oryzae L. and the IC50 value. The results showed that an increase in the concentrations of I. balsamina L. leaves methanol extract significantly raised the fungal growth. Furthermore, the extract inhibition against R. oryzae L. at various concentrations of 0.5; 0.7; 0.9; 1.1; and 1.3% w/v were 10, 21.9, 58.06, 68.06, and 79.72%, respectively, while the IC50 value was 0.896%. Hence, the presence of naphthoquinones and other secondary metabolites are responsible for its antifungal activity. Based on these results, the antifungal potential of I. balsamina L. leaves against soft-rot fungi is useful in the future.

Utilization of Kayu Bawang (Protium javanicum) plant is needed beside its utilization for building material, especially the utilization of the leaves which easily to get. The aim of this research was to describe the potency of Kayu Bawang leaves as tyrosinase inhibitor, an enzyme which responsible to synthesis melanin as natural color of the skin. The leaves of Kayu Bawang macerated with methanol. The methanol extract then partitioned with n-hexane, EtOAc, n-BuOH, and water. All fractions were concentrated and tested its ability to inhibit tyrosinase with two substrates namely L-DOPA (diphenolase reaction) and L-tyrosine (monophenolase reaction). The result showed that n-hexane fraction could inhibit diphenolase reaction with IC50 value of 114.2 ppm. EtOAc fraction could inhibit monophenolase reaction (IC50 834.0 ppm). Methanol extract, n-BuOH fraction, and water fraction could not inhibit tyrosinase activities. The conclusion is nonpolar and semi polar compounds in Kayu Bawang leaves could be utilized as whitening agent.

Light-induced synthesis of micron-sized metallic silver in aqueous extract of Rivina humilis L. fruits and its interaction with Corptotermes curvignathus Salprima Yudha S; Aswin Falahudin; Morina Adfa; Irfan Gustian; Herlina Herlina

The aqueous extract of Rivina humilis was suitable to reduce silver ions (Ag+) to form micron-sized metallic silver at room temperature and without any addition of external reducing agent or stabilizer compounds. The reduction process was assisted by light, indicated by the colour change of the reaction mixture and supported by the appearance of peak at 455 nm in spectrophotometric analysis when the reaction was carried out under room light. Based on transmission electron microscopy (TEM) analysis, the as-prepared metallic silver was in spherical form. The analysis results using particles size analyzer (PSA) show their particles distribution from micro to nano size (average size was 199 nm). The interaction behaviour of micron-sized metallic silver/extract solution with Corptotermes curvignathus termites shows that the silver gives small additional effects along with the activity of the extract.

Sekam dan jerami padi saat ini kurang termanfaatkan oleh masyarakat kelompok Tani Akur Kabupaten Rejang Lebong. Sebagian besar jerami hanya ditumpuk di lahan pertanian atau dibakar. Sedangkan untuk sekam padi, masyarakat hanya menjual dengan harga yang murah atau hanya dibakar jika terlalu menumpuk. Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan pemahaman masyarakat dalam pemanfaatan sekam dan jerami padi sebagai bahan pembuatan asap cair dan pemanfaatannya sebagai biopestisida. Kegiatan dilakukan dengan metode ceramah dan diskusi kemudian dilanjutkan dengan praktik pembuatan asap cair serta penggunaannya sebagai biopestisida. Indikator capaian kegiatan adalah perubahan pemahaman masyarakat tentang asap cair, bahan pembuatan asap cair, cara pembuatan asap cair dan manfaat atau kegunaan asap cair. Persentase peningkatan pemahaman rata-rata dari masyarakat sebesar 96,2%. Hasil praktek/pelatihan berupa asap cair berbahan sekam dan jerami padi yang beraroma khas asap, berwarna coklat kehitaman dengan rendemen sebesar sekitar 40%. Secara umum, kegiatan pengabdian ini dapat menjadi alternatif masyarakat dalam memanfaatkan sekam dan jerami padi sebagai bahan pembuatan asap cair yang dapat dimanfaatkan sebagai biopestisida sehingga dapat meningkatkan pendapatan petani.

This study aimed to determine the antibacterial activity of the ethanol extract of the leaves of Tapak Kuda (Ipomoea pes-caprae) against Staphylococcus epidermidis. The method used was Kirby-Bauer for the antibacterial test with various concentrations of ethanolic extract of I. pes-caprae leaf extract: 5 mg/mL, 20 mg/mL, 35 mg/mL, and 50 mg/mL, with five replications. The antibiotic clindamycin was used as a positive control, while DMSO was a negative control. The results showed that after 24 hours of incubation, the zone of inhibition of bacterial growth was demonstrated by the experimental and the positive control groups, while the negative control did not show the zone of inhibition. The diameter of the largest inhibition zone (11.40 mm) was at a 50 mg/mL test concentration, which was indicated as a strong category. In conclusion, the ethanolic extract of the leaves of I. pes-caprae can inhibit the growth of S. epidermidis at all test concentrations. Keywords: Antibacterial, Ipomoea pes-caprae, Staphylococcus epidermidis
