Abstract

Butterflies are one type of insect that functions as a pollinator. Research on butterflies in the Bodogol Nature Conservation Education Area (PPKAB), has already been published, but research on the correlation of butterflies with flowering plants has not yet been published. The purpose of this study was to determine the correlation between butterflies and flowering plants in the PPKB area. The research was conducted in February-June 2022 in heterogeneous and homogeneous forests. The research was conducted using purposive sampling method. In each observation, 10 plots were observed in heterogeneous on 3 lanes (Rasamala, Canopi, and Aprika), and in homogeneous forest on 3 lanes (Cikaweini-Cipadaranten, and Gembong koneng). Research using cameras and insect nets. In this study, 78 species, 4 families with 261 individuals were found in heterogeneous forests, and 39 species, 5 families with 158 individuals in homogeneous forests. Butterfly families: Papilionidae, Pieridae, Nymphalidae, Lycenidae, and Rionidae. The Nymphalidae family is one of the families with the highest number of species and individuals compared to other families. Based on the index value of butterfly diversity, it is classified as high (heterogeneous) and medium (homogeneous). High evenness index in both habitats. Jamides celeno is one of the dominant species in both habitats. Correlation analysis showed that there was a strong relationship between flowering plants and the number of individual butterflies in both habitats (heterogeneous and homogeneous).

Abstract

Elderly is one of the processes of a person who has entered the final stage of the life phase. Groups categorized as elderly experience a process called the aging process. The nutritional adequacy rate is the average daily nutritional adequacy. Nutritional adequacy is an indicator of food security at the household level and can be measured by the adequacy of energy, protein and fat. The study aims to analyze the cases of nutritional adequacy of the elderly. The method used a quantitative method using a cross-sectional approach that is complemented by interview techniques using a food recall questionnaire. This study shows that the average level of adequacy of energy, and macronutrients (carbohydrates, protein and fat) is included in the sufficient category, while fiber still needs to be improved, because it is included in the insufficient category. The nutritional status of respondents was mostly normal, although some were in the obese category. to maintain a healthy body, an elderly person needs to do routine activities and have food quality by showing the suitability of food intake based on recommendations, namely the existence of a variety of food groups, nutritional adequacy according to needs, moderation and overall balance.

Abstract

The aim of this research was to isolate endophytic fungi from different parts of soursop plantations in Cikareo Village, Sukabumi, West Java and to test their antibacterial activity. The researchers obtained six isolates from leaves, stems, and fruits of the soursop plant. These isolates displayed varying growth abilities, with only two (Le-1 and St-2) found to inhibit the growth of Escherichia coli bacteria. Overall, this study highlights the potential of endophytic fungi from soursop plantations as a source of antibacterial agents.

Abstract

Indonesian native chickens have a high potency to be developed as egg produced chickens such as merawang and arab chicken. A study for genetic quality improvement through merawang and arab chicken crossing has been done and showed that their F1 results have a good heterosis effect. This research was conducted to observe the growth performance of merawangarab x arab and with a backcross breeding concept. The parameters of productivity measured were body weight, feed consumption, and feed conversion. Randomized complete block design used to analyzed the research. The average body weight of A-MA chicken were higher than the body weight of MA-A chicken. The result of statistical test were not significantly (P>0.05). A-MA chicken were more efficient in converting feed than MA-A chicken. Feed consumption and feed conversion between A-MA chicken and MA-A chicken were not significantly.

Abstract

This research aimed to analyze the effect of dosage and time of application and potassium fertilizer to bidara plants’ (Ziziphus rotundifolia) growth. This research was arranged by Split Plot design in a Randomized Complete Block Design (RCBD). The Factor of Potassium time of application, that were during planting, 2 weeks after planting; 4 weeks after planting; 6 weeks after planting, was as the main plot, while the potassium fertilizer dosage of (K2O) 0 kg ha-1, 60 kg ha-1, 120 kg ha-1, 180 kg ha-1 as secondary plot. The results showed that the time of application of Potassium fertilizer had an effect on the height of the best Bidara at the age of 2 week after planting. The 60 kg K2O ha-1 dosage can increase plant height from 2 week after aplication to 10 week after aplication. The applications of 4 week after planting produced in a higher number of shoots than applications at 2 or 6 week after planting. The fertilizer application at 6 weeks after planting showed the highest fresh leaf weight and dry leaf weight which were 50,631 g and 20,900 g and the lowest in application 2 weeks after planting were 24,263 g and 12,925 g. The fertilizer dosage as much as 60 kg ha-1 produced the highest dry weight which 18,069 g. Fertilizing as much as 180 kg ha-1, showed the highest root fresh weight of at 12,757 g, compared to the control (8,900 g). The Potassium application of 6 week after planting produced the longest root growth (20,500 cm) compared to other treatments.
