Abstract

Peanut root nodules can be used as a biological fertilizer. Root nodules are roots containing rhizobium bacteria as nitrogen enhancers, which can be used as biological fertilizers. Nitrogen is an element for forming important compounds in cells, including proteins, DNA and RNA. Cayenne pepper production is low due to lack of nutrients, one of which is nitrogen. To meet this need, researchers use peanut root nodules. The aim of this study was to determine the utilization of peanut root nodules (Arachis hypogaea), as a biological fertilizer for the growth of cayenne pepper (Capsicum frutescens), in an effort to prepare plant physiology practical instructions II. This research is included in pure experimental research and development research. The design used was Completely Randomized Design (CRD). Data collection techniques in this study were through observation and documentation methods, then data analysis used One Way Anova. The population consisted of 5 treatments, namely: 1) P.O (Control with 100% soil); 2) P.1 (3 grams of peanut root nodule fertilizer); 3) P.2 (2.5 grams of peanut root nodule fertilizer); 4) P.3 (2 grams of peanut root nodule fertilizer); and 5) P.4 (1.5 grams of peanut root nodule fertilizer), and repeated 4 times. Parameters observed in this study were plant height, number of leaves, leaf length, leaf width, stem diameter, stem length, and total leaf area. The results of the research on plant height parameters showed that the Fvalue < Ftable 0.05, that is, 1.827 < 3.06, the parameter for the number of leaves with the Fcount < Ftable 0.05, namely 1.500 < 3.06, the leaf length parameter with Fcount < Ftable 0.05, that is, 0.478 < 3.06, the leaf width parameter with a calculated Fvalue < Ftable 0.05, that is, 0.053 < 3.06, the stem segment length parameter with a calculated Fvalue < Ftable 0.05, namely , 0.660 < 3.06, parameter of stem diameter with calculated Fvalue < Ftable 0.05 ie, 0.489 < 3.06, and total leaf area parameter with calculated Fvalue < Ftable 0.05 ie 0.489 < 3.06. Based on the results of the study, all observation parameters did not have a significant effect (non-significant). In the development research, 2 expert validators were used, namely teaching material experts, material expert in plant physiology II and the readability test by 15 students. From the results of data analysis of teaching materials experts, the average value was 3.56, and material experts 3.53. As well as the readability test by 15 students an average of 2.98. So that the practical instructions for plant physiology II are feasible to use without revision.

Abstract

The results of preliminary observations on the Unus River in Mataram City show that the gastropods in each village which the river flows through have different characters according to the activities around the river and the level of river water pollution. Pollution and the high activity of residents who use the river as a residential area, indications of pollution in the Unus River can be seen from the condition of the river estuary which is quite dirty, so great ecological pressure is occurring in the river, it is necessary to conduct research on the community structure of macrozoobenthos, especially water snails as a bioindicator of water quality in the Unus River, Mataram City in an effort to develop an ecological module. The aims of this study were: 1) to find out how the pattern of distribution of gastropods in the Unus River, Mataram City; 2) identify the types of gastropods found in the Unus River, Mataram City; 3) reveal the population of Gastropod dominance that dominates the Unus River in Mataram City; 4) analyze the population density of Gastropods in the Unus River, Mataram City; 5) analyzing the diversity of gastropod species in the Unus River, Mataram City; and 6) developing research results on distribution patterns of gastropods as bioindicators of water pollution in the Unus River, Mataram City in an effort to develop an ecological module. This type of research is descriptive exploratory and developmental research for the development of ecological modules. The sampling technique used was purposive sampling technique and the length of the transect used was 30 m. Based on the results of the study, the highest morbidity index was the Thiara requenti species with a value of 0.253 which was in the regular category. Found 12 species from 5 families namely; Pomacea canaliculata, Mellanoides plicaria, Apella demisum, Mellanoides puncata, Taribea granifera, Goniobasis virginica, Fillopaludina javanica, Thiara scabra, Thiara sp, Thiara requenti, and Mellanoides tuberculata. The highest Gastropod dominance population was owned by the Mellanoides plicaria species with a total of 0.48. The highest population density is occupied by the species Thiara requenti with a value of 7.3. The highest level of Gastropod diversity is located at station 2 with a value of 1.82. Based on the results of the validation and readability test of the ecological module, an average value of 90 and 82.9 was obtained for the legibility test, so it can be concluded that the module is very feasible to use.
