Abstract

Liquid organic fertilizer from gamal leaves contains the nutrients N, P, K, Ca and Mg which are useful in plant growth and vegetative development. This research aims to determine the effect of the best dose of gamal leaf liquid organic fertilizer in increasing the growth of mustard greens (Brassica juncea L.). This type of research is a pure experiment using a Completely Randomized Design (CRD), which consists of 5 dose treatments, namely P0 0 ml/l water, P1 30 ml/l water, P2 60 ml/l water, P3 90 ml/l water, and P4 130 ml/l water. Each treatment was repeated 5 times. The parameters observed were plant height, number of leaves, and leaf width. Next, the data was analyzed using One Way ANOVA 5%. The results of the research showed that the best dose of gamal leaf liquid organic fertilizer was in the 130 ml/l treatment, namely the highest plant height was 21.50 cm, the largest number of leaves was 11.8, and the largest leaf width was 10.20 cm. The significant value of the 5% ANOVA test results is 0.000. There is a significant value, namely P < 0.05, so gamal leaf liquid fertilizer has a significant effect on each dose of gamal leaf liquid fertilizer on the vegetative growth of mustard greens. The results of the validation analysis of Student Worksheets (LKM) showed that from the three expert validators, an average validation result of 82% was obtained with very good qualifications, and was declared suitable for use as a LKM guide in plant physiology courses.

Abstract

Tris yolk is a diluent that can be used to maintain and protect spermatozoa during storage so that they can be used in the process of artificial insemination. The length of storage greatly affects the motility and viability of spermatozoa in semen. The purpose of this study was to determine the effect of long storage of egg yolk tris diluent on the motility and viability of simental bovine spermatozoa. This research was carried out at the Banyumulek Artificial Insemination Center Laboratory, West Nusa Tenggara Province, from July to Desember 2024. The study of the effect of long storage of egg yolk tris diluent on the motility and viability of simental bovine spermatozoa used a randomized experimental method complete with four treatments and six repeats. Each treatment, namely P1, P2, P3, and P4, was carried out by mixing 0.075 ml of semen and 0.3 ml of egg yolk tris diluent stored for 24, 48, 72, and 96 hours. The data obtained were processed by variety analysis method (ANOVA) and Duncan's further test. The results showed that P1 treatment with a storage period of 24 hours resulted in the highest average motility and viability values of 63.33 ± 6.055 % for motility and 63.50 ± 6.892 % for spermatozoa viability. P4 treatment with a storage period of 96 hours still showed a good mean value with motility values of 40.83 ± 7.360 % and spermatozoa viability of 53.50 ± 12.112 %. Thus, egg yolk tris is suitable for use as a semen thinner for artificial insemination because it is able to maintain the motility and viability of spermatozoa even for a long time of 96 hours.

Abstract

Fasciolosis merupakan penyakit yang disebabkan oleh parasit Fasciola sp. yang menyerang hewan ruminansia dan sering menyebabkan kerugian dikalangan peternak berupa turunnya tingkat produktivitas ternak bahkan sampai menyebabkan kematian pada ternak. Pengobatan secara rutin dengan anthelmintik yang sama dapat menimbulkan resiko terjadinya resistensi. Daun kelor merupakan jenis hijauan pakan ternak yang selain dapat memenuhi kebutuhan protein dan serat yang tinggi juga dapat berfungsi sebagai obat herbal anthelmintik. Penelitian ini bertujuan untuk mengetahui efek vermisidal ekstrak daunkelor terhadap Fasciola Sp. secara in vitro ditinjau dari lama waktu kematian. Sampel yang digunakan dalam penelitian ini adalah cacing Fasciola yang di ambil dari Rumah Potong Hewan (RPH) Majeluk. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dengan 5 pengulangan, perlakuan pada penelitian ini terdiri dari ekstrak daun kelor konsentrasi 2,5%, 3,5% dan 4,5%. Albendazole sebagai kontrol positif dengan serta kontrol negatif menggunakan aquades. Data yang diperoleh dianalisis dengan sidik ragam analysis of variance (ANOVA), diuji lanjut menggunakan uji duncan. Hasil penelitian ini menunjukkan perlakuan ekstrak daun kelor dengan konsentrasi 2,5%, 3,5%, 4,5% memiliki pengaruh yang berbeda nyata (P>0,05) dalam mempercepat waktu kematian Fasciola sp. dibandingkan kontrol negatif (aquades), namun masih lebih rendah dibanding perlakuan Albendazole. Pemberian Albendazole menyebabkan kematian cacing lebih cepat dari pada ekstrak daun Kelor.

Abstract

Eggs as a staple food for the community are increasingly in demand because they are very easy to obtain, easy to process and have high protein content. Duck eggs stored at room temperature can only last 10-14 days, after which the eggs have decreased in quality. The purpose of this study was to determine the effect of using betel nut seed solution as a preservative on the storage time and quality of duck eggs. This type of research is a True-experimental study with a Completely Randomized Design (CRD), two factorial, consisting of concentration treatments (0%, 15%, 30%, 45%, and 60%) and storage time treatments (14 days, 21 days, and 28 days) with 3 replicates. Chemical and physical test data were analyzed using the ANOVA test (5%) using SPSS for Windows version 20.0. The interaction of betel nut seed solution concentration and storage time gave no significant effect on the pH value (Fhit = 1.125 < Ftab = 1.375), Yolk Index (Fhit = 1.002 < Ftab = 1.454), and Weight Loss (Fhit = 0.614 < Ftab = 0.638). However, the length of storage of duck eggs had a significant effect on the yolk index (Fhit = 21.821 > Ftab = 21) and weight loss (Fhit = 12,569 > Ftab = 12.001).
