Abstract

Animal manure and water hyacinth become waste if not used. One of its uses is as raw material for biogas. The purpose of this study was to determine the effect of the type of manure on the formation of biogas from water hyacinth as seen from: 1) the rate of biogas formation, 2) the temperature of the slurry, 3) the pH of the slurry, and 4) the weight of the biogas produced. Research with Completely Randomized Design (CRD) consisted of five treatments (P); P1: cow dung + water hyacinth + water, P2: buffalo dung + water hyacinth + water, P3: goat dung + water hyacinth + water, P4: horse dung + water hyacinth + water, and P5: broiler chicken dung + water hyacinth + water . Each treatment was repeated 4 times to obtain 20 experimental units. The composition of the raw material mixture consists of 8 kg of water hyacinth chopped 2 cm + 3 kg of livestock manure + 2 liters of water. Parameters observed were: rate of gas formation, slurry pH, slurry temperature, and weight of biogas produced. The research was conducted at the Biology Education Laboratory, Faculty of Teacher Training and Education, Kapuas Sintang University. Data were analyzed by ANOVA at 5% significance level using SPSS 16.0 and BNT test if there was a significant difference between treatments. The results showed that the type of manure only had a significant effect on the weight of biogas formed, but had no significant effect on the rate of biogas formation, slurry pH, and slurry temperature. Thus the five types of manure can be used as a starter in the manufacture of biogas made from water hyacinth.

Abstract

Baning Nature Park is located on the Ana River, Sintang District, Sintang District, West Kalimantan Province, is an ex-situ conservation area of ​​dry lowland plants with various collections of plant habitus, both from trees, shrubs, herbs, lianas, and others. other. The existence of butterflies in a habitat has a role as pollinating insects which have a very important position in maintaining the balance of nature. Butterflies aside from being natural pollinating agents, can be used as an indicator in testing environmental quality, by observing the state of their habitat. This study aims to find out what types of butterflies are found in the Baning Nature Park and their ecological roles. This research is a type of exploratory research. Data collection was carried out using a belt transect, by circling the Baning Nature Park. Catching butterflies is done using sweeping technique. Observations made at the Baning Nature Park found 15 species in 4 different families. These species namely; Arhopala centaurus, Leptosia nina, Appias olferna, Eurema blanda, Catopsilia pomona, Eurema hecabe, Junonia hedonia, Junonia atlites, Junonia iphita, Hypolimnas bolina, Phaedyma columella, Elymnias hypermnestra, Tanaecia trigerta, Papilio memnon, and Papilio polytes. The ecological role of the butterfly is as a pollinating organism. Nectar-producing plants in Baning Nature Park which are frequently visited by butterflies, namely, the species Psydrax dicoccos and Ixora sp.
