Efektivitas Campuran Ekstrak Daun Srikaya (Annona squamosal L.) dan Rimpang Kunyit (Curcuma domestica Val.) pada Mortalitas Larva Spodoptera litura F. (Lepidoptera: Noctuidae)

Spodoptera litura F. larvae (Lepidoptera: Noctuidae) are polyphagous insects that cause damages to many types of plantations and horticulture that need to be protected. One of environmentally friendly method to protect ecological balance is the use of botanical insecticides whose bioactive compounds come from plant extracts. This study used a mixture of two plant extracts from A. squamosa leaves extract and C. domestica rhizome exstract (the mixed of experimental extracts). The mixed of experimental extracts are synergistic so that they are more effective and need a lower concentration to cause the mortality of S. litura larvae than the use of a single extract. The aims of the research were to know the efficacy of the mixed of experimental extracts on the mortality of S. litura larvae and determine the value of LC50 and LC90 extract test on its mortality. The initial and efficacy test were conducted by bait dip into the mixed of experimental extracts. The mortality data were analyzed using ANAVA, then continued by Duncan test and Probit analysis. The results of this research showed that the mixed of experimental extracts were effective to kill S. litura larvae. The calculated result of LC50 and LC90 showed that the LC50 value of the experimental extracts on the second and the third instar larvae were 5.252 ppm and 10.559 ppm, respectively, and the LC90 value for both instar larvae were 11.124 ppm and 13.638 ppm, respectively. It could be concluded that the mixed of experimental extracts is effective in S. litura larvae mortality and more effective in the mortality of the second instar larvae than that of the third instar larvae. Therefore, this test extract mixture can be developed further in a greenhouse to evaluate the effectiveness in the mortality of S. litura larvae which can be used as an alternative to controlling S. litura larvae with an environmentally friendly material in farmers.   Keywords: control, extract, mortality, Spodoptera litur

Sosialisasi Pengaplikasi Centrifugal Force Dalam Memproduksi Minyak Kelapa Murni

Cooking oil is one of the staple ingredients that is widely used in household and industrial needs. The high price of cooking oil has an impact on the food security of a family. Repeated use of cooking oil will also have an impact on family health. So it is necessary to socialize the healthy and quality cooking oil using virgin coconut oil. The purpose of this socialization was directed to the group of housewives in Pumo Village, Wuluhan District, Jember Regency. The economic condition of this housewife is classified as lower middle class. The Pumo Village Housewives Group (partner) is located in a coastal area with extraordinary coconut potential. Utilization of coconut is only limited to being sold in the form of coconuts, either young (degan) or old (copra). Though the potential will be greater if the processing is carried out, especially in the form of pure coconut oil. The solution offered to this problem is the application of science and technology with simple technology, namely centrifugal force as an effort to become independent partners in producing virgin coconut oil. The virgin coconut oil produced is not only to support family food security, but also to be a business opportunity for partners. The results of this service, the community can know the techniques of making, packaging products and entrepreneurship in the field of making virgin coconut oil

ANALISIS KANDUNGAN PROLIN TANAMAN KANGKUNG (Ipomoea reptana Poir), BAYAM (Amaranthus spinosus), Dan Ketimun (Cucumis sativus L.)

 Abstract. Suatu respons fisiologi yang cukup penting ialah kemampuan tanaman mempertahankan tekanan turgor dengan menurunkan potensial osmotik sebagai mekanisme toleransi terhadap cekaman kekeringan. Dalam proses penyesuaian osmosis, senyawa-senyawa terlarut yang biasa diakumulasi ialah gula dan asam amino terutama prolina (Girousse et al. 1996). Secara umum kadar prolina daun mengalami peningkatan akibat cekaman kekeringan. Kekurangan air pada tanaman dapat menghambat laju fotosintesis, karena turgiditas sel penjaga stomata akan menurun. Perlakuan analisis kandungan prolin pada jaringan tanaman ini yang memiliki kandungan prolin terbesar pada tanaman bayam (Amaranthus spinosus) sebesar 30,28; kemudian disusul dengan tanaman ketimun (Cucumis sativus, L) sebesar 27,01 dan yang terkecil kandungannya pada tanaman kangkung (Ipomoea reptana Poir). Dalam analisis kandungan prolin bahwa tanaman yang tergolong C3 yaitu pada tanaman kangkung (Ipomoea reptana Poir) dan ketimun (Cucumis sativus, L); sedangkan untuk tanaman C4 pada tanaman bayam (Amaranthus spinosus). Key Words : Kandungan Prolin tanaman kangkung (Ipomoea reptana Poir), bayam (Amaranthus spinosus) , dan ketimun (Cucumis sativus L.

Melalui bimbingan teknis pembelajaran daring, guru yang awalnya kurang mahir menjadi lebih mahir dalam tatap muka secara maya, share materi, penugasan, kuis, dan ujian

PENGARUH ZPT NABATI DAN MEDIA TUMBUH TERHADAP PEKEMBANGAN KOPI ROBUSTA

Indonesia occupies the 4th position of the 5 main coffee producing countries in the world. Coffee plants are a high foreign exchange earner in the Indonesian economy. Data from the Central Statistics Agency (BPS) show that Indonesia's coffee production in 2021 was the highest in the last decade, reaching 774.6 tonnes. This number increased by 2.75% from the previous year of 753.9 thousand tonnes. Coffee seed germination takes a long time due to seed dormancy. Coffee growth can be optimal with the provision of growth regulators. Good planting media can produce quality coffee seeds, because in good media there are nutrients needed by plants. The research was conducted at the Jember State Polytechnic Soil Wire House Laboratory in February-May 2022. Data were analyzed using Factorial RAK with a 5% BNJ follow-up test. The results showed that the combination treatment of planting media and natural ZPT concentrations had a significant effect on the generative growth of Robusta coffee (Coffea canephora L) including germination percentage, root length, height and seedling diameter

The study of slurry recirculation to increase biogas productivity from Jatropha curcas Linn. capsule husk in two phase digestion

The purpose of this study was to obtain the best slurry recirculation treatment for two-phase digester system which produced the highest biogas production in the DH-JcL substrate. The study was conducted in the laboratory using 750 mL and 2 L of plasticdigester and biofilter plastic as growth immobilize. The slurry recirculation treatment consisted of the recirculation of 50 %slurry to methanogenesis digester, 50 % slurry to hydrolysis digester, and 25 % slurry to hydrolysis digester combined with 25 % to methanogenesis digester. The highest daily biogas production was obtained from the recirculation of 50 % slurry to hydrolysis digester. However, the best slurry recirculation treatment, which was more stable in longer period, was 50 % slurry to methanogenesis digester
