Abstract

Hydrilla verticillata is one of water plants that has some bioactivities. The presence of secondary metabolites in H. verticillata is responsible for the bioactivity. The purpose of this study was to determine and separate bioactive compounds from fraction of petroleum ether (PE) and ethyl acetate (EA) as a result of hydrolysis of H. verticillata ethanol extract. H. verticillata was extracted by maceration method using ethanol solvent, hydrolyzed with hydrochloric acid and partitioned respectively with petroleum ether and ethyl acetate. Crude ethanol extract, PE and EA fraction were identified their secondary metabolites. The phytochemical test results showed H. verticillata ethanol extract containing alkaloid compounds, flavonoids, tannins, saponins, triterpenoids, and steroids. PE fraction contained steroids and terpenoids, while EA fraction contained flavonoids, steroids, and triterpenoids. Analytical thin layer chromatography analysis showed n-hexane : ethyl acetate (4: 1) eluent as the best mobile phase for separating steroids. The preparative thin layer chromatography analysis of H. verticillata fraction using n-hexane : ethyl acetate (8: 2) as mobile phase resulted in 17 and 14 spots of PE and EA fractions, respectively.Keywords: Hydrilla verticillata, thin layer chromatography, phytochemicals Hydrilla verticillata merupakan salah satu tanaman air yang banyak memiliki bioaktivitas. Adanya metabolit sekunder pada H. verticillata yang bertanggung jawab terhadap bioaktivitas ini. Tujuan penelitian ini adalah untuk mengetahui dan memisahkan senyawa aktif dari fraksi petroleum eter (PE) dan etil asetat (EA) hasil hidrolisis ekstrak etanol H. verticillata. Ekstrak diperoleh dengan metode maserasi menggunakan pelarut etanol, dihidrolisis dengan asam klorida dan dipartisi masing-masing dengan petroleum eter dan etil asetat. Ekstrak kasar etanol, fraksi PE dan EA diuji kandungan metabolit sekundernya. Hasil uji fitokimia menunjukkan ekstrak etanolH. verticillata mengandung senyawa alkaloid, flavonoid, tanin, saponin, triterpenoid, dan steroid. Fraksi PE mengandung steroid dan terpenoid, sedangkan fraksi EA mengandung flavonoid, steroid, dan triterpenoid. Hasil analisis KLTA menunjukkan eluen n-heksana : etil asetat (4:1) sebagai fasa gerak terbaik untuk memisahkan steroid.Hasil analisis KLTP fraksi H. verticillatamenggunakan perbandingan fasa gerak n-heksana : etil asetat (8:2) menghasilkan spot fraksi PE dan EA berturut-turut sebanyak 17 dan 14 spot.Kata Kunci: Hydrilla verticillata, kromatografi lapis tipis, uji fitokimia

Abstract

Penelitian ini memiliki tujuan dalam rangka memastikan bagaimana aktivitas terkait literasi, hambatan, dan inisiatif sekolah berkontribusi terhadap perkembangan minat membaca peserta didik yaitu siswa dalam pendidikan. Dalam meneliti Hal ini bersifat kualitatif. Kepala sekolah, pengajar, dan peserta didik SD Negeri Desa Masaran Kecamatan Bluto dijadikan sebagai subjek penelitian. Dua bentuk cara digunakan untuk mengumpulkan perdataan: observasi, dan wawancara. Berdasarkan temuan penelitian, terbukti bahwa kegiatan literasi membantu siswa menjadi lebih tertarik membaca. Namun, mempraktikkan kegiatan literasi di sekolah dapat menjadi tantangan karena kurangnya sumber daya, kurangnya variasi dalam metode yang digunakan, dan kurangnya disiplin diri siswa dalam menyesuaikan diri dengan kegiatan tersebut.

Abstract

Examining how purchasing habits and sales promotions affect impulsive purchases on the Lazada marketplace is the goal of this research. Explanatory research methodology was used in this quantitative investigation. Questions and paperwork were the methods utilized to obtain the data. In Jatimulyo Village, Lowokwaru District, Malang City, 100 respondents from the Lazada marketplace were selected by the purposive sample technique. This study's findings indicate that impulse buying on the Lazada marketplace is positively impacted, albeit partially and simultaneously, by sales promotions and shopping habits.It is necessary to optimize sales promotion strategies by providing price discounts and addling more prizes so that consumer impulse buying increases. Additionally, it is necessary to optimize the lifestyle shopping strategy by providing more attractive fashion advertisements so that the consumer impulse buying increases.

Abstract

Al-Banjari is a type of Islamic musical art that combines the singing of sholawat or praises for the Prophet Muhammad SAW with the rebana and other traditional musical instruments. The language used by the Al-Banjari community is Indonesian and Arabic, but we often hear some people using regional languages, specifically Madurese, during events such as religious gatherings, weddings, and so on. The factors contributing to the phenomenon of decreasing use of the Madurese language among the younger generation are: 1) young people prefer to use Indonesian in daily conversations, 2) many Madurese families who work or migrate to other cities are starting to abandon the Madurese language, 3) parents no longer use the Madurese language when communicating with their children, 4) young people are more interested in foreign languages than their own regional language, 5) lack of knowledge and understanding about the Madurese language. The type of research used is descriptive qualitative with a sociolinguistic approach. this association plays a significant role in fostering a love for language identity among young people.
