Abstract

Durian is a fruit that has a distinctive aroma and bioactive compounds that are beneficial for human health. This study aimed to study the effect of various vegetative propagation techniques on the success of durian plant propagation. The research design used was a non-factorial randomized block design (RAK) with three treatments and five replications. The vegetative propagation technique using wedge grafting had a significant effect on the time of shoot emergence and the number of tillers, while insertion grafting had a significant effect on seedling height. From these three treatments, it is recommended to use shoot grafting treatment for durian plant propagation.

Abstract

The distribution of parrots in Indonesia, one of which can be found in West Papua, precisely in the Malagufuk forest area, Sorong Regency. These types are also usually used as objects of observation by tourists. To complete the data on parrots in the Malagufuk forest, it is necessary to conduct research, both on their species and their distribution patterns, so that later this data can become a reference in efforts to protect and preserve these species, considering that this bird species is still included in the bird list vulnerable to extinction. The Point of Abundance Index (IPA) or point count is used as a method in this study, using 4 path observations with a length of 1000 meters each, distance between count points of 100 m and a circle diameter of 50 meters. Observation time is 20 minutes for each circle or counting point, which is carried out at 06.00 to 09.00 WIB and 15.00 to 17.00 WIB. The Morisita index (Id) is used to analyze the pattern of distribution of parrot species. There were 5 types of parrots from 3 families found at the study site, namely the rainbow lorikeet (Trichoglossus haemadotus) and parrot parrot (Eclectus roratus) from the Psittacidae family, the yellow-crested cockatoo (Cacatua galerita) and the king's cockatoo (Probosciger atterimus) from the family Cacatuidae and the Ambon king parrot (Alisterus amboinensis) from the Psitaculidae family. The results of the distribution pattern analysis using the Morisita Index (Id) means that there are 4 types of parrots whose distribution pattern is grouped while 1 other species cannot be analyzed because it only covers 1 individual.

Abstract

Soil conditions need to be evaluated to determine the potential productivity index of the land. One of the food crops that has long been developed by farmers in Cimaung Village, Cikeusal District is peanuts. The decline in soil conditions is caused by more intensive land management, so it is necessary to analyze the potential productivity index of the soil. This study aims to determine the potential productivity index of the soil for peanut land use which can display soil productivity before burial. This research was conducted in a farmer's garden, in Cimaung Village, Cikeusal District, Serang Regency, Banten Province (Coordinates 6o12'14'' S and 106o11'52'' E). The magnification of the potential index of soil productivity used the modified Storie (1987) method, which was adjusted to the research location using several soil property parameters, which effective depth of soil, soil texture, permeability, C-organic, pH, N-total, P and CEC. The results showed that the potential productivity index of the resulting soil was in class IV with a value of 28% in the bad category with the limiting factor "having limitations on locational commodities". Suitability limitations are influenced by soil fertility and soil acidity, so it is necessary for wise land management managers to make improvements in the management of fertilization using organic matter.

Abstract

This decrease in land productivity is closely related to the reduced organic matter content in the soil, so efforts are needed to overcome it by utilizing asystasia gangetica weeds as a cover crop. The purpose of this study was to determine the benefits of A. gangetica as a cover crop in improving soil chemical properties under shaded and unshaded conditions. The research was conducted at the Experimental Garden of the Faculty of Agriculture, Islamic University of North Sumatra (UISU), Johor Building, Medan. The research method used was a split plot design in a factorial randomized block design. The first factor as the main plot is Shade (N) and the second factor as the subplot is Cover crop (C) with three replications. The results of this study showed that A. gangetica grown as a cover crop was able to improve soil chemical properties by increasing the organic C, total N, and available K content of the soil after treatment. Likewise, the combination of both shaded and unshaded treatments with cover crop A. gangetica (N1C1 and N0C1) was able to improve soil chemical properties by increasing the C-organic, total N, and available K-content of the soil after treatment.

Abstract

The existence of mangrove forests around Jeflio Beach, Mayamuk District, Sorong Regency, ecologically will affect the biodiversity of coastal natural resources and socio-economically will have an impact on the growth of business income of the community around the area. The purpose of this study is to determine the public’s perception of the existence of mangrove ecotourism objects in Jeflio Village, Mayamuk District, Sorong Regency. This study uses a qualitative descriptive analysis. The data in this study are primary data and secondary data obtained by means of observation and interviews. The community’s and increases people’s income. There is an influence in terms of the existence of ecotourism and the level of income on the characteristics of the community.
