Abstrak: Resistensi temephos (abate) sebagai larvasida telah terjadi di Jawa Tengah sejak tahun 2007 dan ditahun 2017 Jawa Tengah tercatat sebagai provinsi dengan jumlah kasus DBD terbanyak ketiga secara nasional. Oleh karena itu, penelitian ini bertujuan untuk memanfaatkan ekstrak daun kenikir (Cosmos caudatus) sebagai larvasida pengganti temephos. Proses penelitian dimulai dengan ekstraksi fraksinasi, kemudian dilanjutkan dengan screening fitokimia dan uji larvasida menggunakan metode yang direkomendasikan oleh WHOPES dengan mengamati mortalitas larva nyamuk A. aegypti pada jam ke 24, 48 dan 72 pada berbagai konsentrasi larutan uji (600, 800, 1000, 1200, 1400, 1600, dan 1800 ppm). Data mortalitas larva dianalisis dengan menggunakan Rancangan Acak Kelompok (RAK) subsampling. Perbandingan antar perlakuan diuji dengan uji Beda nyata Jujur (BNJ) dengan tingkat kebermaknaan 5%. Analisa probit pada data mortalitas menghasilkan nilai dosis efektif LC50. Hasil penelitian menunjukan diantara ketiga fraksi, ekstrak kenikir fraksi heksan memiliki efek larvasida terbaik (mortalitas 71,67%) dengan LC50 sebesar 1762 ppm pada waktu paparan 72 jam. Golongan senyawa kimia yang menyebabkan efek larvasida ini adalah alkaloid, terpenoid, dan flavonoid. Walaupun ekstrak fraksi heksan tanaman ini memiliki efek larvasida, potensi pengembangan tanaman ini sebagai pengganti temepos kecil dikarenakan nilai LC50 yang tinggi pada waktu paparan yang lama.Kata kunci: Larvasida; temephos; resistensi; Cosmos caudatus; potensiAbstract: Temephos resistance as larvicide has occurred in Central Java since 2007 and in 2017 Central Java was recorded as the 3rd highest dengue cases in Indonesia. Hence, this study attempts to use extract of Cosmos caudatus as temephos substitute. The study start with fraction extraction of dried C. caudatus leaf followed by phytochemical screening of the extract and larvicide assay was carried out using method recommended by WHOPES by observing the mortality of A. aegypti larvae at 24, 48, and 72 hours on various extract concentration (600, 800, 1000, 1200, 1400, 1600, and 1800 ppm). The mortality data was analyzed using Randomized Block Design (RBD) subsampling (P<0,05). Probit analysis on mortality data result in the LC50. The result showed the most effective fraction is hexane fraction (mortality 71,67%) with LC50 ÃÂ1762 ppm at 72 hours exposure time. The active compound in the hexane fraction were alkaloid, terpenoids, and flavonoids. Even though the hexane fraction extract has the most larvicidal effect, this extract has low potential to developed as replacement to temephos because the LC50 was high and longtime exposure ÃÂ Keywords: Larvicide; temephos; resistance; Cosmos caudatus; potential

This study aims to determine the yield of wild spinach seed oil obtained by continuous extraction methods using Soxhlet apparatus for 10.5 hours in n-hexane solvent, the physio-chemical properties, and the composition of wild spinach seed oil using the Gas Chromatography-Mass Spectrometry (GC-MS) method. Refinement of wild spinach seed oil was done by degumming and neutralization. The yield of wild spinach seed oil extraction before refinement was 4.36 ± 0.29% (w/w) while after refinement was 0.68 ± 0.033% (w/w). Physio-chemical properties of wild spinach seed oil after refinement was as follows: water content 0.37%; peroxide value 9.5 meq/kg; acid value of 0.53 mg KOH/g oil; saponification value 208.9 mg KOH/g oil. The results of GC-MS analysis showed that the wild spinach seeds were composed of 5 main components: dodecanoic acid (0.28%); tetradecanoic acid (0.08%); palmitic acid (1.31%); squalene (94.9%); and linoleic acid (3.34%).

Nutritional problems still become a crucial issue in Indonesian public health. Fulfillment of nutritional balance is expected to improve life quality. In humans, one of the nutrients that play a role in the growth of brain and nervous system functions is PUFA, such as omega-6 and omega-3. Besides, fulfillment of nutritional balance can prevent some diseases; especially linoleic acid used to prevent some diseases. Linoleic acid is an omega-6 and essential fatty acid. Linoleic acid is the main essential fatty acid because it is the precursor for GLA, DGLA, and AA. Omega-6 works with omega-3 and some omega-3 benefits are supported or can arise by omega-6 presence. Studies reveal that watermelon contains high linoleic acid. This study aimed to determine the optimum temperature and ratio of fatty acids: urea for the isolation of linoleic acid from watermelon seed oil. The method used was urea inclusion with a variety of temperatures (-6oC, 6oC, 18oC) and the ratio of fatty acid: urea (1:1; 1:3; 1:5). The results showed the optimum watermelon seed oil linoleic acid isolate at 18oC and the ratio of fatty acids: urea 1:5 with linoleic acid purity (%) of 82.53%.

Stekurmin MD is a syrup preparation formulated from the extract of Stevia rebaudiana leaves, temu lawak (Curcuma zanthorrhiza), and honey. One of the active compounds in Stekurmin MD products is phenolic and flavonoid compounds in which the active phenolic and flavonoid compounds can be degraded during the storage period. This study aimed to determine the shelf life of Stekurmin MD products based on the degradation of phenolic compounds and flavonoids. The Accelerated Shelf Life Test (ASLT) method was used in determining the shelf life kinetics of this product. Phenolic and flavonoid concentrations were determined using the UV-Vis spectrophotometric method with the gallic acid standard for phenolic and quercetin standard for flavonoids. Degradation of phenolic and flavonoid compounds was determined every 7 days during 35 days of storage at 25, 35, 45, and 55°C ± 2°C. In natural ingredients, there is a multi-mechanism reaction. The shelf life of Stekurmin MD products based on the degradation of phenolic and flavonoid active ingredients at room temperature were 39.909 days and 23.53 hours, respectively.

Resistance to temephos as a larvicide of A. aegyptimosquitoes has occurred in Indonesia. Therefore, it is necessary to look for other active compounds that can act as larvicides, but also environmentally friendly. This study used leaf and roots extract of T. erectahexane and acetone fraction as larvicide. The process begins with drying followed by extracting samples (leaves and roots of T. erecta) each with hexane and acetone solvents. Test solutions were made with a concentration of 0, 0.0075, 0.015, 0.03, and 0.1% (w/v) of the extract produced. Larvicide test was carried out referring to WHOPES by observing the mortality of instar larvae 3 and 4 in each extract. The results obtained showed the mortality percentage of larvae increased with increasing concentration and exposure time in both types of larvae. The lowest LC 50 was obtained from the root extract of hexane fraction (37 ppm) for 3rd instar larvae and acetone fraction (61 ppm) for instar 4 larvae. Keywords: Larvae, A. aegypti, T. erecta.
