Abstract

The Mount Biru protect forest is still maintained the biodiversity so that it is able to support a variety of animals in it, one of which is a habitat for the release of the javan langurs group (T. auratus). This study aims to determine the daily behavior of the javan langur after rehabilitation and release to evaluate the development of population behavior and barriers in the same group since 2014. The study used a focal animal sampling method combined with scan sampling to observe daily behavior (eating, social, resting, and moving) one female javan langur released in 2014. It was observed that post-release individuals had higher resting activities (38.91%) and the lowest allo-grooming social activities (5.08%). The results of the different test calculations using Chi Square can be concluded that there are significant differences in the daily behavior of the Javan langur after release in 2015, 2019 and 2021.

Abstract

One of the local souvenirs from Jambi is accessories made from the seed bark of the sebalik sumpah tree. The sebalik sumpah tree is currently quite rare. Through DNA isolation, sebalik sumpah is one of the efforts of genetic conservation and as a first step in cultivating sebalik sumpah trees. DNA isolation is the initial stage in molecular analysis. The purpose of DNA isolation is to obtain genomic DNA from a sample. Plant DNA isolation generally uses fresh plant samples, with young and soft plant parts. This is recommended to obtain good quality genomic DNA. However, with the limitations of fresh samples, a method is needed that is able to extract DNA from plants that have changed shape and have undergone processing. Each plant requires a different method to obtain DNA. The CTAB (Cethyl Trimethyl Ammonium Bromide) buffer method is a method commonly used in plants because it is able to extract DNA with high polysaccharide and phenol content, so many have modified the method. This study aims to determine the success of the CTAB method without nitrogen in extracting processed materials and the length of incubation time at the precipitation stage. Extraction was carried out by liquid nitrogenless CTAB method with the addition of PVP (Polyvinylpolypyrrolidone). The results show that the CTAB method without liquid nitrogen is able to extract plant samples that have undergone processing and the length of incubation time at the precipitation stage affects the DNA produced.

Abstract

Since ancient times, woven fabric craftsmen in the Ende area have used tarum leaves as a dye in their woven fabrics. Extraction of color pigments in tarum leaves is carried out by soaking in water or seawater for a certain length of time so as to produce quality color pigments.This study aims to determine the stability of natural dyes in tarum leaves which are used as dyes for woven fabrics in the Ende area of ​​East Nusa Tenggara which were extracted using water and seawater as solvents. The research was carried out in the laboratory of the Faculty of Agriculture, University of Flores using the experimental method. The results showed that tarum leaves produced the optimum wavelength when soaked for 24 hours and there was a decrease in the color stability of the tarum leaf extract due to storage factors, increased temperature, duration of sunlight and increased concentrations of oxidizing agents.

Abstract

This study was conducted at Syurgar ecoutourism site, subdistrict of Sausapor Tambrauw district. Data was collected from June to July 2020 using survey method, direct catching, cage trap and interview. This study aimed to list the wildlife species, especially Birds, Mammals Herpetofauna, and Butterflies in order to complete data of the government of Tambrauw District for the purpose of Syurgar ecotourism development. This study recorded that there were 15 birds’ species of 13 families, 12 mammals’ species of 6 family, 4 herpetofauna’s species of 4 families, and 25 butterflies of 4 families. Syurgar has a potential to be a birdwatching site. There are several appealing birds, including Lesser bird-of-paradise (Paradisaea minor), king bird of paradise (Cincinurus regius), blyth’s hornbill (Rhyncetores plicatus), sulphur-crested cockatoo (Cacatua galerita). Endemic species of mammals include long-beaked echidna (Zaglosus bruijnii), dorcopsis/forest’s wallaby (Dorcopsis sp.), northern common cuscus (Phalanger orientalis), common spotted cuscus (Spilocuscus maculates), old world fruit bats (Dobsonia sp.), great flying fox (Pteropus neohibernicus). Endemic species of herpetofauna include frogs (Papurana sp.), Papua wrinkled ground frog (Cornufer papuensis). Eventually, some butterflies’ species include redeye bushbrown (Mycalesis aethiops), bushbrown (Mycalesis elia), and Papuan gull (Cepora abnormis). It is strongly suspected that several birds, mammals, herpetofauna, and butterflies have not been recorded due to time constraints. Therefore, further study is recommended for data completion.

Abstract

Directional felling is a technique that directs fallen trees in a predetermined direction to minimize damage to residual stands and understory plants and facilitate subsequent stages of timber handling. One of the felling techniques used in private forest harvesting was the rope-assisted directional felling technique. The study aimed to analyze and evaluate the effectiveness of the rope-assisted directional felling technique in private forests. The study was conducted in a private forest managed with an agroforestry system in Probolinggo, East Java. The number of sampled trees was 31 trees. The sampled trees were felled to the predetermined directions: to a stretched rope between two spar trees or the safe area. Felling errors, hang-ups, and the presence of barber chairs were used to assess the effectiveness of the rope-assisted felling technique. The average diameter of the felled trees was 23.4 cm and 20.8 m in height. The ropes-assist directional felling technique produced a hang-up tree of 19.35% of the total felled trees. Directional felling using ropes made fallen trees from close to the opposite direction of the natural felling direction. The ropes-assisted felling technique made all felled trees fall in the predetermined direction without producing barber chairs, but still causing hang-ups.

Abstract

The increase in aquaculture businesses in the coastal areas of Seruway District, Aceh Tamiang Regency, has resulted in high conversion of mangrove forests into ponds. If management is not carried out, it will have an impact on coastal environmental degradation. Therefore, it is necessary to look for a sustainable pond management model. One model is silvofishery. In developing this silvofishery model, biophysical environmental data, social and economic conditions of pond cultivation are needed. The aim of this research is to determine the biophysical, social performance, income level and feasibility of a silvofishery system pond business. The research was conducted using descriptive methods with survey techniques. The research results show that the silvofishery ponds at the research location use a partite pond model. From the analysis of biophysical properties, overall results were obtained, the conditions were suitable for the development of milkfish and tiger prawn cultivation. From social performance, the results showed that silvofishery system pond farmers are still of productive age and have an average pond area of 5 ha. The income obtained from silvofishery system ponds is IDR 19,560,000/ha/year/farmer. Silvofishery pond system If the R/C value is greater than 1, then silvofishery pond farming is worth pursuing.
