Abstract

The conditions in which plants grow affect plant growth and development. If the conditions in which the plant grows are not suitable, its growth will be disrupted and the yield of plant production is not optimal. This research was carried out in two locations, namely in Perhutani land with an altitude of 1110 meters above sea level and community plantations with an altitude of 914 meters above sea level. The type of research used is descriptive qualitative with exploratory sampling. The results showed that ecological factors affect plant morphology. Different light intensities cause the leaves on smallholder plantations to be smaller in size to reduce water evaporation and the distance between the segments of Coffea arabica L. on perhutani land has a longer internode distance due to etiolation. The shade trees found in smallholder plantations are Maesopsis eminii, Engl., Leucaena leucocephala subsp. Glabrata, Pterocarpus indicus, Hibiscus tiliaceus, Toona sureni, Melia azedarach, Leucaena leucocephala. The shade trees on Perhutani land are Pinus merkusii and Ficus benjamina L. Keywords: morphology, ecology, Coffea arabica L, shade trees. ABSTRAK Kondisi tempat tumbuh tanaman mempengaruhi pertumbuhan dan perkembangan tanaman.

Abstract

Apis mellifera honey bee is the most widely cultivated bee species in Indonesia, one of which is the Kembang Joyo farm. The need for bee feed in nature is dwindling and causes the use of additional feed to maintain bee colonies by breeders. The variety of feed types causes the need for research on bee preferences for additional feed to find the type of feed that bees most prefer and can be reached by farmers. The purpose of this study was to compare the preferences of honey bees to various types of supplementary feed at Kembang Joyo Farm and to determine the type of supplementary feed that Apis mellifera honey bees preferred. This research method is an experimental method with 6 treatments and 23 replications which were analyzed through the ANOVA test which was then continued by the Tukey test using the PAST application. The results showed that each type of feed was favored by bees with different numbers of visitors. The type of feed that was most preferred by bees based on the number of visitors was cane sugar solution with 116 individual bees visitors in one replication, while based on feed consumption the most consumed was cane sugar solution with feed consumption of 0.24 ml/individual. Apis mellifera honey bee likes cane sugar solution based on the aroma factor and sucrose content.

Abstract

One effort to improve the quality of males is to collect semen to be used for the Artificial Insemination (AI) process. The ejaculate fraction is one of the factors that can affect the quality of fresh spermatozoa in cattle. This study aims to determine the quality of fresh spermatozoa in Simmental cattle and Limousin cattle for various fractions of ejaculate. This study used fresh semen with each cow aged 3-4 years and 5-6 years. This research method used a Completely Randomized Factorial Design with 4 repetitions. Observation of spermatozoa quality was carried out macroscopically and microscopically. The data obtained were analyzed using the F test and Least Significant Different test (BNT). The results showed that semen volume had a significant difference (p<0.05) for different types of cows, ages, and ejaculatory fractions. The color, pH, consistency and concentration of spermatozoa had significant differences (p<0.05) for different ejaculate fractions. There was no significant difference (p>0.05) for motility and abnormalities of spermatozoa for different types of cows, ages and ejaculatory fractions. It can be interpreted that different breeds of cattle and ages can have a significant effect on semen volume, while the ejaculate fraction can have a significant effect on the volume, color, pH, consistency and concentration of spermatozoa. While the different types of cattle, age, and ejaculate fraction did not have a significant effect on the motility and abnormalities of spermatozoa.

Abstract

Mangroves are an important habitat for fish communities, as spawning, growing and foraging areas. This study aims to compare the species composition, presence frequency and structure of fish communities in different mangrove habitats. The research was conducted at Banyuurip Mangrove Center, Ujung Pangkah District, Gresik Regency, East Java, during July-August 2020. Determination of purposive sampling locations based on physical differences in mangrove habitats. Systematic sampling method was used to estimate the number of mangrove species using belt transects. Fish sample collection uses basic gill nets that are placed at high tide in each mangrove habitat. The results showed that the total number of individual mangrove vegetation was 505 from 12 species, the number of species and individual mangrove vegetation differed between habitats, and the highest was found in coastal mangrove habitats. The number of fish was found as many as 181 individuals from 11 species, 10 families and 5 orders.
