The present research was conducted to study the efect Of Extract Fruit Paria(Momordica charantia, L.) On Morphology Spermatozoa Epididymis of mice (Mus musculusL.). The test animal used were 16 male mice with weight 20-30 gr aged 2-3 month into 4dosage treatments groups i.e. P0 control (water), P1 (25%/bw), P2 (50%/bw) and P3(75%/bw). The ectracts were given orally to all conducted during 34 day. At the 35th daybody weight mice be pondered the next surgery and conducted taking cauda epididymis forobservation morphology spermatozoa. The data obtained were analysed by using theAnalysis of Variance Test (ANOVA Î± = 0,05) and t-Test Least Significant Differences. Theresults showed the ectractsFruit Pariawere given on all dose reduce the percentage ofmorphology spermatozoa normal mice (Musmusculus, L.) is P1 (32%), P2 (47%), and P3(67%).Keywords : Ectracts Fruit Paria, Morphology Spermatozoa, Epididymis, Mice

Patikan kerbau (Eupobia hirta L.) contains some anti-diarrheal compounds or containanti-bacterial substances which are alkaloids, flavonoids and tannins. This study aims to determine theeffect of extract of patikan kerbau on the growth of bacteria causing diarrhea (E.coli). This researchtests phytochemical properties and examines inhibition zone (hallow zone). The design used wasCompletely Randomized Design (CRD) with six treatment of patikan kerbau extract (0 ppm, 1500 ppm,1750 ppm, 2000 ppm, 2250 ppm and 2500 ppm) and four replications. Data were analyzed by usingANOVA and if there is a significant difference, the test will be followed by a DNMRT test at 5%significance level. Phytochemical test was based on the formed color intensity. The results showedthat - average inhibition zone diameter on treatment 2500 ppm with a diameter of 10.75 mm was notsignificantly different from 2250 ppm treatment with diameter of 9.75 mm. However, it wassignificantly different with treatments of 2000 ppm, 1750 ppm, 1500 ppm and control. The controlgroup (0 ppm) with a diameter of 6 mm (no inhibition zone formed) was significantly different fromother treatments. Phytochemical test showed that the active compound contained in patikan kerbauare alkaloids, flavonoids and tannins. These compounds have anti-bacterial property and can be usedas an anti-bacteria.

Penelitian ini bertujuan mengetahui pengaruh Asam Giberelat (GA3) terhadap perkecambahan danpertumbuhan vegetatif duku. Perlakuan dengan pemberian GA3 pada beberapa konsentrasi yaitu 10 ppm, 50 ppm,100 ppm, 150 ppm, 200 ppm, 250 ppm, dan 0 ppm sebagai kontrol. Penelitian menggunakan Rancangan AcakLengkap (RAL) dengan empat kali ulangan. Pengamatan dilakukan terhadap waktu perkecambahan, dayaperkecambahan, tinggi tanaman, dan biomas (berat daun spesifik). Hasil analisis ragam menunjukkan bahwapemberian GA3 pada konsentrasi yang berbeda memberikan pengaruh berbeda nyata terhadap waktuperkecambahan dan daya perkecambahan (kecambah normal),. Berdasarkan hasil penelitian disimpulkan bahwa GA3dapat mempercepat perkecambahan biji duku, konsentrasi optimal untuk parameter perkecambahan yang diamatiadalah 100 dan 150 ppm.

Penelitian ini dilakukan untuk melihat pengaruh dari ekstrak daun sirih terhadap pertumbuhan bakteriStreptococcus viridans penyebab penyakit karies gigi. Rancangan percobaan yang digunakan adalahRancangan Acak Lengkap (RAL) dengan 6 perlakuan konsentrasi (0%, 10%, 30%, 50%, 70% dan 90%).Pengamatan dilakukan terhadap diameter daerah hambat menggunakan kertas cakram. Berdasarkan hasilpenelitian diperoleh rata-rata diameter daerah hambat (zona hallow) tertinggi pada pemberian konsentrasi90%, tidak berbeda nyata dengan konsentrasi 50% dan 70%. Selanjutnya pemberian konsentrasi ekstrakdaun sirih 0% dan 10% memberikan hasil terendah terhadap diameter daerah hambat dan berbeda nyatadengan perlakuan lainnya. Konsentrasi ekstrak daun sirih 50%-90% merupakan konsentrasi yang terbaikdalam menghambat pertumbuhan bakteri Streptococcus viridans.

Banana (Musa sp.) is the most widely consumed fruits since the children age up to the elderly. This is because bananas have quite complete nutrient content such as carbohydrates, proteins, vitamins and minerals, making it beneficial for the human body. People normally only consume and discard any banana skin. Therefore; it needs solutions to deal with the banana peel waste. Banana peels contain high enough nutrients that are carbohydrate 18.5%, phosphorus 28 mg, water 72 g, and some other chemical substances. The high nutrient content on the banana peel is potential to be used as food, one of which is in the form of nata. Nata is a product of microbial fermentation using Acetobacter xylinum. Nata can be made from coconut water waste, liquid waste or waste bark out pineapple and banana peel waste (Nata de Banana Skin). This study aimed to determine the effect of various types of banana peels using A. xylinum on the quality of nata de banana skin. The results showed that different types of banana peel affect the quality of Nata de Banana Skin, both on its flavor and its yield of Nata de Banana Skin. The pisang raja skins give the most optimal results for nata thickness and also perform the best organoleptic values.

This study aims to determine the optimal concentration of Bacillus licheniformis required in the formation of liquid sugar from cassava waste, the value of sugar and value starch contained in degraded cassava skin waste. The design used in this study was Completely Randomized Design (RAL) with 4 treatment concentration of cassava leaf extract (Manihot utilissima Pohl.), Ie 0 concentration, 1.5 ml concentration, 2.5 ml concentration and 3.5 ml of concentration B. licheneformis. Data were analyzed using analisis (ANOVA) followed by Duncan's range test (DMRT) with a 5% confidence level. The results of the study showed that all treatments had a significant effect on the administration of B. licheniformis concentrations. Treatment using 1.5 ml B. licheniformis concentration on cassava skin substrate weighing 1 gram after Duncan's test range (DMRT) with 5% confidence level resulted Reduction sugar value of 6.07%.

Angso Duo Market is the largest traditional market in the city of Jambi, with an area of ± 5 Ha. The amount of waste produced by Angso Duo market every day is around 105 tons per day with a ratio of 70% biodegradable waste, 25% recycled (organic and paper) and 5% other waste. Of the 75% of waste that is around 60% is waste in the form of vegetables, most of which are mustard and cabbage. Vegetable waste has great potential to be used as organic fertilizer because it has good and complex nutrients such as protein, fat carbohydrates, calcium, phosphorus, iron, vitamins A, B and C, folic acid, fiber, water and sodium. The advantage of liquid organic fertilizer is that it contains enough nitrogen as a constituent of plant protein and chlorophyll. The results showed 6 types of bacteria namely Planococus, Neisseria, Halobacter, Azomonas, Azotobacter and Bruccella which were formulated into liquid fertilizers with a basic substrate of vegetable cabbage and mustard waste.Then tested the ability of bacteria to dissolve nitrogen, phosphorus and potassium as potential bacteria as liquid fertilizer
