Tujuan penelitian adalah menguji toksisitas tepung pelepah aren yang diawali dengan maserasi dengan pelarut etanol kemudian difraksinasi dengan petroleum eter, etil asetat dan air. Masing-masing ekstrak dilakukan uji toksisitas dan uji fitokimia. Metode yang digunakan untuk pengujian toksisitas adalah Brine Shrimpt Lethality Test (BSLT) dengan menggunakan larva udang jenis Artemia salina Leach sebagai bioindikator dan uji fitokimia. Hasil uji toksisitas ekstrak etil asetat tepung pelepah aren adalah bersifat sangat toksik dengan nilai LC50 < 1000 ppm (7,76 ppm) yang diikuti oleh ekstrak petroleum eter 10,69 ppm kemudian ekstrak etanol 15,81 ppm dan terakhir ekstrak air 26,92 ppm. Hasil uji fitokimia tepung pelepah aren mengandung beberapa senyawa metabolit sekunder yaitu alkaloid pada ekstrak etanol, petroleum eter, etil asetat dan air, triterpenoid hanya pada ekstrak etanol, petroleum eter dan etil asetat sedangkan ekstrak air negatif. Selanjutnya tanin yang positif adalah ekstrak etanol, etil asetat dan air sedangkan petroleum eter negatif. Kesimpulan tepung pelepah aren toksik terhadap larva udang artemia salina Leach dan mengandung senyawa metabolit sekunder alkaloid, triterpenoid dan tanin The purpose of this study was to examine the toxicity of Aren’s midrib flour that was preceded by maceration with ethanol solvent then concentrated and fractionated with petroleum ether, ethyl acetate and water. Each extract was tested for toxicity and phytochemical testing. The method used for toxicity testing is the Brine Shrimpt Lethality Test (BSLT) by using artemia salina Leach shrimp larvae as bioindicators and phytochemical tests. The results of the toxicity test of the ethyl acetate extract of aren’s midrib flour are very toxic with LC50 value <1000 ppm (7.76 ppm) followed by petroleum ether extract 10.69 ppm then ethanol extract 15.81 ppm and finally water extract 26.92 ppm. The results of phytochemical tests of aren’s midrib flour contain several secondary metabolites, namely alkaloids in ethanol extract, petroleum ether, ethyl acetate and water, triterpenoids only in ethanol extract, petroleum ether and ethyl acetate while negative water extracts. Furthermore, for tannins that are positive are ethanol, ethyl acetate and water extracts while petroleum ether is negative. Conclusion Aren’s midrib flour is toxic to the larvae of shrimp artemia salina Leach and contains secondary metabolites of alkaloids, triterpenoids and tannins

Penelitian ini dilakukan untuk mengetahui efek gliserol + NaCl pada dendeng babi yang disimpan pada suhu kamar. Plot split dalam desain waktu digunakan dalam penelitian ini; Faktor A adalah konsentrasi Gliserol + NaCl (dibagi dalam 3 level kombinasi) sebagai berikut A₁ = Gliserol 15% + NaCl 5%, A₂ = Gliserol 10% + NaCl 10%, A₃ = Gliserol 5% + NaCl 15% dan faktor B adalah durasi penyimpanan pada suhu kamar (dibagi dalam 3 lama waktu yang berbeda) sebagai berikut B₁ = 10 hari, B₂ = 20 hari, B₃ = 30 hari; dengan tiga replikasi. Variabel yang diamati adalah kadar air, pH dan jumlah mikroba. Hasil penelitian menunjukkan bahwa penggunaan Glycerol-NaCl memberikan efek yang sangat berbeda (P <0,01) pada kadar air dan jumlah mikroba pada dendeng babi, tetapi tidak pada pH dendeng babi. Ditemukan juga bahwa durasi penyimpanan pada suhu kamar memberikan efek yang sangat berbeda (P <0,01) pada semua variabel dendeng babi. Singkatnya, penggunaan Gliserol 5% + NaCl 15% dapat memperpanjang umur simpan dendeng babi hingga 30 hariThe study was done in order to know the effect of glycerol+NaCl on jerky pork kept at room temperature. A split plot in time design was used in this study; A Factor was Glycerol+NaCl concentration(divided in 3 combination levels) as follows A₁= Glycerol 15% + NaCl 5%, A₂= Glycerol 10% + NaCl 10%, A₃= Glycerol 5% + NaCl 15% and B factor was duration of storage at room temperature (divided in 3 different length of time) as follows B₁= 10 days, B₂= 20 days, B₃= 30 days; with three replications. The variables observed were water content, pH and the number of microbes. The results showed that the use of Glycerol-NaCl gave significantly a very different effect (P <0.01) on water content and microbial amounts of jerky pork, but not on the pH of jerky pork. It was found also that the duration of storage at room temperature gave significantly a very different effect (P <0.01) on all variables of jerky pork. In short, the use of Glycerol 5% +NaCl 15% could extend the shelf life of jerky pork until 30 days
