Abstract

ABSTRACT As a maritime country with vast waters, Indonesia has many opportunities to utilize marine resources as a source of bioactive compounds that have the potential as active medicinal ingredients. One of the marine biotas that potentially contains the active compounds is the Vannamei shrimp's shell (Litopenaeus vannamei), which is commonly found as waste along the coast of Gunungkidul, Yogyakarta. The shrimp’s shell contains astaxanthin, a potential source of antioxidants for the health industry. The purpose of this study was to compare the astaxanthin extraction yield from L. vannamei shrimp shells using sunflower oil and 70% ethanol. The Astaxanthin extraction used sunflower oil and ethanol 70% as solvents and was done by maceration method, while the phytochemical test and Astaxanthin profiling used Thin Layer Chromatography and Spectrophotometer with Kelly and Harmon (1972) [5] calculations as well as pure Astaxanthin standards. The extraction yield of the 70% ethanol extraction was further processed by column chromatography using ether: ethanol (8: 2) as mobile phase. The highest Astaxanthin yield (220 mg / g of shrimp powder) was obtained from the extraction with sunflower oil compared to the 70% ethanol solvent, while the fractionation result with a chromatographic column from a crude extract of ethanol 70% showed high astaxanthin yield of 220.77 mg. / g fraction. The results of the fraction test on rat neutrophils, the best percentage reduction was at a concentration of 150 mg / g bw of rats.

Abstract

The purpose of this study is to determine the potential extract of areca nut (Areca catechu L.) seeds, skin and the combination of the two extracts in killing the Aedes aegypti larvae. This study used a Completely Randomized Design in the seed extract test with a concentration of 16000, 17000, 18000, 19000 and 20000 ppm and skin extract with concentrations of 7000, 8000, 9000, 10000 and 11000 ppm. The factorial design was used in the combined extract of 0:100; 25:75; 50:50; 75:25 and 100:0. Each treatment used 4 replications. Data were analyzed by ANOVA and then continued by Tukey, LSD and Duncan tests. The last, data were analyzed by probit analysis to determine LC50 and LC90. The result indicates that areca nut seed and skin contain flavonoid, alkaloid, palmitic acid, phenols, terpenoids and steroids which are toxic. The killing power of seed extract was 64-97% (24hours) and 100% in all treatments (48hours). Skin extract was 52-88% (24hours) and 58-93% (48hours), while the combination extract was 55 -93% (24hours) and 95-100% (48hours). Concentration of 19000 ppm of seed extract with 95% mortality at 24 hours was effective when compared to the WHO standard (2005), while the skin extract had a lower LC value than the other two extracts.

Abstract

Tanaman berkhasiat obat banyak dimanfaatkan oleh masyarakat di Indonesia secara turun-temurun untuk mendukung kesehatan. Inventarisasi dan pemanfaatan beragam tanaman obat mutlak dilakukan untuk pengembangan potensinya dalam menunjang kesehatan. Pemanfaatan jamu sebagai produk olahan tanaman obat mulai mendapatkan perhatian lebih dari pemerintah melalui institusi kesehatan. Pengabdian ini bertujuan untuk membuat percontohan taman tanaman obat keluarga (Toga) di Dusun Ngelosari, Kecamatan Piyungan, Kabupaten Bantul yang memadukan rintisan ekowisata lereng bukit dan pengolahan tanaman obat keluarga. Kegiatan pengabdian ini didasarkan pada analisis situasi dan permasalahan kesehatan di lingkup Puskesmas Piyungan. Berdasarkan identifikasi masalah dan analisis kebutuhan yang dilakukan bersama puskesmas dan kader kesehatan maka pendekatan pengembangan percontohan taman toga, pelatihan dan pendampingan pada kelompok wanita tani (KWT) dipilih sebagai pendekatan yang diharapkan mampu menyelesaikan permasalahan kesehatan dan ekonomi masyarakat. Program terealisir dalam bentuk persiapan dan observasi lokasi taman Toga, pengembangan taman Toga percontohan, pelatihan budidaya tanaman obat, pasca panen dan pengolahan, serta pengemasan dan pemasaran produk herbal. Kegiatan ini mempunyai hasil berupa Taman Toga Ngupoyo Sehat yang menjadi sumber bahan baku produk jamu yang dihasilkan oleh KWT setempat. Selain meningkatkan pendapatan KWT setempat, pelaksanaan program dapat dipergunakan sebagai model sinergisme pengembangan konservasi dan peningkatan kesehatan masyarakat.
