Abstract

The aim of this research is to develop a practical manual for the Plant Physiology I course. This research is included in development research. The design used in this research uses a 4D model which was adapted into a 3P model (Definition, Design and Development). The research instruments used were validation sheets and readability test sheets. This development research uses two expert validators, namely content/material experts and teaching materials experts as well as readability tests by students. Data collection techniques use validation techniques and readability tests. The data analysis technique used is the percentage technique. The research results showed that the value of the content/material expert validator was an average of 3.15, the teaching material expert validator was an average of 3.11, and the readability test by 20 students was an average of 3.08. Thus, teaching materials in the form of a Plant Physiology I practical manual are suitable for use without revision.

Abstract

Peanut (Arachis hypogaea L.) is a legume crop and is one of the second highest yielding secondary crops after soybeans. Peanut production in Indonesia tends to fluctuate and is still not able to meet the needs of the community every year. To produce quality seeds, one of the ways that plant breeders do is by crossing. The cross in this study was a peanut cross between the national variety and the local Bima variety. The purpose of this study was to determine the vigor and viability of peanut sprouts from crosses between national and local varieties of Bima. This research is included in pure experimental research. The design used in this study was a completely randomized design. The data in the research that has been collected through observation and documentation methods are then analyzed using ANOVA One Way. Based on the results of the study, the data on viability parameters were obtained, namely: the highest percentage of germination was obtained by F1A seeds (Rhinoceros Variety x Local Bima) with a value of 86.66% while the lowest percentage of germination was F1C seeds (V. Kancil x Local Bima) with a value of 20%. For the parameter of germination speed, the F1 seed which had the highest seed germination speed was F1E (V. Pelanduk x Local Bima) with a value of 2.33/day while the lowest germination rate was F1C (V. Kancil x Local Bima) with a value of 0.58/day. From all research data, it was found that data from all parameters experienced significant variations or differences with P Value < 0.05 in each treatment.
