Abstract

Xylocopa latipes Drury are one species of bee found in the Hymenoptera order, in the family Anthophoridae. Carpenter bees, which are essential for plant pollination, build their nests in decaying wood and bark. Carpenter bees visit the bean crop to collect pollen and nectar for their hives. This study aims to determine the visit of the wood bee X. latipes on long bean plants in Central Sulawesi. The study employed a descriptive survey methodology that involved field sampling at bean planting and direct observation of X. latipes in the field. measured the temperature and the light intensity. The findings revealed that X. latipes visits to the bean crop at Desa Nambaru, Kecamatan Parigi Selatan, Kabupaten Parigi Moutong average 58,3 people each visit. The morning at 08.30 am averages 21 X. latipes visits; the afternoon at 15.30 pm averages 9 Xylocopa latipe visits; and the afternoon at 11.30 am averages 2 Xylocopa latipe visits. The amount of light present during X. latipes visit to the bean crop has a significant impact. Weather variables like temperature, humidity, and wind speed had an impact on the multivariate regression's very real relationship to X. latipes visit to bean planting.

Abstract

The performance of laying hens is affected by feed quality and can be seen from feed consumption, egg weight and hen day production (HDP). The aim of this study was to determine the quality of feed on the performance of laying hens. Sampling was carried out via interview on farmers in East Lombok representing each sub-district with a minimum population of 500 laying hens. Sampling of feed ingredients and 20 eggs was carried out on each farm for analysis in the laboratory. The descriptive analysis was performed on acquired data. The results showed that farmers in East Lombok used different percentages of corn, concentrate and mineral feed ingredients. The nutritional content of feed given consist of crude protein (14,17-16,90%), crude fat (3,17-3,36%), crude fiber (6,13-7,06%), calcium (1, 03-1,29), phosphorus (0,26-1,33%) and metabolic energy (2751,96-2925,79 Kcal/kg). The conclusion is some farmers in East Lombok Regency provide feed that does not suitable to the nutritional needs required by laying hens, namely the content of crude protein, calcium and phosphorus according to SNI standards which has an impact on reducing egg weight and HDP.

Abstract

Pepper is a plantation commodity that belongs to the spice category and has an important role in Indonesia's economic growth. Southeast Sulawesi is one of the centers for the development of pepper plants, especially in the South Konawe area. The purpose of this study was to determine the effect of indigenous mycorrhizae on the growth of pepper plants which were carried out in Sindangkasih Village, West Ranomeeto District, South Konawe Regency. Analysis of dry weight and infection of indigenous mycorrhizae on the roots of pepper plants was carried out at the Agrotechnology Laboratory, Faculty of Agriculture, University of Haluoleo Kendari. Data analysis in this study used a single factor Randomized Block Design (RBD) with 4 treatments and 3 replications, so there were 12 trials. The treatment consisted of 4 levels, namely without mycorrhizae (A0), 10 grams of mycorrhizae (A1), 15 grams of mycorrhizae (A2) and 20 grams of mycorrhizae (A3). The results showed that the application of indigenous arbuscular mycorrhizae had an effect on the growth parameters of pepper plants in the form of plant height, number of leaves and number of tendrils, where A3 produced higher plant height, number of leaves and number of tendrils and was significantly different from other treatments. Treatment A2 was not significantly different from treatment A1 but significantly different from treatment A0 (without mycorrhiza). Mycorrhizal inoculation of 20 grams/polybag can cause root infection of pepper plants to increase by 80.00%.

Abstract

The study aims to investigate the life cycle and success of the Attacus atlas L. larvae fed with mahoni leaves and sirsak leaves. Observations are done on the development of larvae from eggs until they reach the adult butterfly phase. The study was conducted between November 2022 and January 2023 using direct observation methods to look at the life cycle of Attacus atlas L. Observations were carried out in the morning and in the evening. Data on the success rate of life of larvae in each stage of development is also recorded. Research has shown that the life cycle of A. atlas L. larvae on mahoni leaf foods has a shorter phase period compared to sirsak leaf feed. The age of the A. atlas L. larvae tends to be higher when feeding the sirsak leaves, especially in the subsequent instar phase. However, further research is needed to gain a more comprehensive understanding of the other factors that affect the success of the life of A. atlas L. larvae on various types of feed. This research contributes to the biological understanding and management of A. atlas L. larva conservation, as well as providing important insights into the conservation efforts of this species as a wild silk insect that has significant economic value.

Abstract

Banana (Musa spp.) is a leading commodity that makes a major contribution to national fruit production. One of the districts in Lampung Province which has a significant contribution to Indonesia's banana production is Pesawaran Regency. The molecular marker used in this study is Sequence-Related Amplified Polymorphism (SRAP). This study aims to determine the genetic diversity of bananas, determine the suitable combination of SRAP primers to determine the genetic diversity of bananas and determine the similarity relationship of bananas in the Pesawaran District. The total genomic DNA was extracted using DNeasy Plant Mini Kit (Geneaid) according to the protocol from the manufacturer followed by their amplification using SRAP primers. Similarity analysis was carried out based on similarity index values and dendrogram construction using the NTSYS 2.0 program. Research results show that a total of 204 loci (167 polymorphic loci and 37 monomorphic loci) were obtained from 9 selected primer combinations. The genetic diversity of 19 banana cultivars originating from Pesawaran Regency resulted in low genetic diversity values (0-0.27). Banana kinship based on Sequence Related Amplified Polymorphism (SRAP) markers divided 19 banana cultivar samples and 4 wild banana samples into 2 large clusters with similarity coefficient values between 0.70-0.97.

Abstract

Cayenne pepper (Capsicum frutescens L.) is one of the horticultural commodities that has high economic value and market demand. Cayenne pepper production in West Kalimantan is low due to soil conditions dominated by peatlands with high acidity and low soil fertility. Resetting soil fertility can be done using liquid organic fertilizers (LOF) such as coconut water waste and pineapple peel. Both types of LOF have nutrient values that are sufficiently beneficial for plants. This study aims to determine the response of cayenne pepper plants to applying both types of liquid organic fertilizer (LOF) alone and the effect of the combination of liquid organic fertilizer of coconut water waste and pineapple peel. This study uses a completely randomized design (CRD) with a factorial pattern consisting of 2 factors, namely coconut water waste and pineapple peel waste liquid organic fertilizer. Each factor consists of 4 treatment levels and is repeated 4 times, namely A (coconut water POC) A0 = 0 ml (control); A1 = 150 ml; A2 = 250 ml; A3 = 350 ml; B (pineapple peel POC) B0 = 0 ml (control); B1 = 50 ml; B2 = 100 ml; B3 = 150 ml. Data were analyzed using the Analysis of Variance (ANOVA) test and continued with the Tukey test at the 5% test level. The results showed that the treatment of  350 mL coconut water POC / 150 mL pineapple peel POC in combination gave a significantly different effect on height, number of branches, flowering time, number of flowers, number of fruits, wet weight and dry weight of plants.
