The economic value of patchouli oil is largely determined by its quality. The research objective was to study the quality of patchouli oil in North Kolaka. Quality analysis based on physical chemical properties of patchouli oil. The quality of patchouli oil (sample 1a and 1b) products from the distillation industry in North Kolaka has fulfilled most of the specifications of SNI quality standards. Patchouli oil (Sample 2), obtained by processing patchouli plant samples from North Kolaka by good and correct postharvest and refining methods, the quality has met all SNI quality specifications. Patchouli oil in North Kolaka has good quality potential and can meet Indonesian patchouli oil quality specifications.
ABSTRAKPenelitian ini bertujuan untuk mengetahui hubungan pembelajaran daring dimasa pandemi Covid-19 terhadap motivasi belajar kimia siswa SMA Kelas XI di Kota Kendari. Penelitian ini merupakan penelitian deskriftif kuantitatif dengan menggunakan metode survei. Populasi dalam penelitian ini adalah guru dan siswa kelas XI IPA SMA di Kota Kendari dengan jumlah guru sebanyak 17 orang dan siswa sebanyak 2266 orang. Pengambilan sampel menggunakan teknik purposive sampling dengan jumlah sampel siswa sebanyak 325 orang, sedangkan sampel guru adalah sejumlah populasi. Pengumpulan data menggunakan kuisioner (angket), observasi, dan wawancara terstruktur. Data dianalisis secara deskriftif dan inferensial. Hasil analisis data menunjukkan bahwa proses pembelajaran daring terlaksana cukup baik dengan kategori sedang dengan nilai rata-rata sebesar 69,61 dan nilai rata-rata motivasi belajar sebesar 71,08 tergolong kategori sedang Hasil uji korelasi sederhana menunjukkan pembelajaran daring dengan motivasi belajar mendapatkan nilai koefisien korelasi sebesar 0,148 yang tergolong sangat rendah. Dengan demikian data tersebut menunjukkan bahwa hubungan pembelajaran daring dimasa pandemi covid-19 terhadap motivasi belajar kelas XI SMA di Kota Kendari sangat rendah. Kata Kunci : Pembelajaran Daring, Motivasi Belajar.
Herbal medicine as a traditional medicine based on local wisdom in the Covid 19 pandemic is the alternative for the community to keep the health of the body. Specific drugs for the cure of Covid-19 disease have also not been found yet so the death of Covid-19 patients remainsat anytime. In this case this study aims to know the content of secondary metabolite compounds and radical scavenger activity of “kayu jawa” (L. coromandelica) leaf steeping and “Salam” (S. polyanthum) leaves from Southeast Sulawesi as well as their rational combination based on the radical scavenger activity of DPPH (2,2-difenyl-1-picrilhydrazil). The analysis of the content of secondary metabolite compounds in the steeping of DKJ (Daun Kayu Jawa) and DS (Daun Salam) is applied by phytochemical method and radical scavenger activity is determined by the DPPH method. The main focus of steeping is determined by the approach of the picnometer. The combination of DKJ and DS is made each with 6 variations based on the IC50 steeping value, then converted in the form of weight (grams) of DKJ and DS powder so that 36 combinations are obtained. The result of phytochemical analysis of DKJ and DS steeping showed the presence of flavonoids, saponins and polyphenols, except tannins only exist in the steeping of DS. The radical scavenger activity of DKJ and DS steeping showed IC50 values of 408.95 ± 0.075 µg/mL and 259.05 ± 0.092 µg/mL. The combination that showed the highest DPPH radical scavenger activity of 88.050.03% occurred in the combination of E1 with a ratio of 2IC50 DK: 1/8IC50DS (1,089: 0.128) grams. DPPH radical scavenger activity approaching 50% occurs in the combination of A2 and B1 with a ratio of 1/8IC50 DKJ: ¼IC50DS (0.068:0.256) grams and ¼IC50 DKJ: 1/8IC50DS (0.136:0.128) grams with values of (49.11 0.04) % and (52.87 0.05) % respectively.
The aims of this study is to ivestigate the correlation between online learning during the Covid-19 pandemic and the motivation to study chemistry for Class XIth grade of senior high school students in Kendari City. This research is a quantitative descriptive research using survey method. The population of the study were teachers and students in XIth grade of scienein Kendari City with 17 teachers and 2266 students. The sample used purposive sampling technique with a sample of 325 students, while the teacher sample was the entire population. The data used are questionnaires (questionnaires), observations, and structured interviews. Data were analyzed descriptively and inferentially. The results showed that the online learning process was running quite well in the medium category with an average value of 71.21, and the average value of learning motivation of 71.12 belonging to the medium category. The results of a simple correlation test show that online learning with learning motivation gets a correlation coefficient value of 0.148 which indicates that there is a positive and significant relationship between online learning during the covid-19 pandemic on learning motivation and learning achievement of XI grade of senior high school students in Kendari City.
