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

Land cover change is strongly influenced by land use. Increasing population growth results in the need for food and other needs. The causes of land use change are influenced by human activities or activities that directly affect land use. Physical, social and economic factors are factors that trigger land use change in Laiya Village, Cenrana District. The purpose of this study was to describe land cover change in Laiya Village, Cenrana Subdistrict for the period 2011, 2015 and 2019 and to determine the driving factors that influence land use change around the forest area of Laiya Village. This research uses GIS analysis to analyze and see land cover changes that occur and qualitative descriptive methods to determine land use changes. The period 2011-2015 mixed dryland agriculture decreased in area by 2,893.19 ha while shrubs increased in area by 2,744.51 ha. The period 2015-2019 mixed dryland agriculture experienced an increase in land area of 3,030.64 ha and shrubs experienced a decrease in land area of 2,744.51 ha. Factors that influence land use change are physical, social and economic factors. Socio-economic factors are the main driving factor of land use change, the need for land for settlements is increasing due to the high population density that occurs around the forest area of Laiya Village, Cenrana District, Maros Regency which causes people to utilize land as an economic source.

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

The Sintuwu Maroso KPH area, which is located in Bomba Village, South Lore District, has quite high biodiversity, one of which is butterflies. Butterflies are insects that belong to the order Lepidoptera. Butterflies play an important role in the ecosystem and maintain balance and enrich natural biodiversity. These insects are also important in agriculture, art, culture and human civilization. The Sintuwu Maroso KPH area, Bomba Village, South Lore District, Poso Regency, is a primary forest with maintained sustainability. Primary forest is a good place for butterfly habitat, so it is necessary to protect these butterflies. And research on these butterflies in the Sintuwu Maroso KPH area is still rare, as butterflies play an important role in plant pollination. Therefore, it is necessary to research the diversity of butterfly types.  This research was carried out for 2 (two) months from October 2023 to November 2023, which took place in the KPH Sintuwu Maroso area, Bomba Village, South Lore District, Poso Regency, Central Sulawesi. Data collection and the number of individual types of butterflies used the Point Count method with eleven points. Data analysis used in the research is: species diversity index, species richness index, and species evenness index.

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.

Abstract

Halaban Monitoring Post, Sei Betung Resort, Gunung Leuser National Park is a rehabilitated forest restoration location since 2017 after previously being diversified from oil palm land. The location has currently become a habitat for various types of animals, including bats. The identification of bat species at the Halaban Monitoring Post is conducted to assess the presence of fauna, with important ecological roles in pollination. Identification was conducted using mist nets installed at five observation points. Our observations showed that 87 individuals of Microchiroptera family bats were found, belonging to 4 species: Cynopterus brachyotis (38 individuals), Cynopterus minutus (15 individuals), Glischropus tylopus (1 individual), Hipposideros cervinus (33 individuals). Further analysis showed Shannon-Wiener diversity index ranges from 0.0 to 0.94 and Margalef species richness index ranges from 0.0 to 0.69. Bat abundance tends to be evenly distributed with an evenness index of 0.0 to 1.35. There is a dominant species at one of the locations with a dominance index value of 0.85.

Abstract

Institutions are the rules of the game that can regulate the activities of Farmers Group members to support Social Forestry activities. The study aimed to analyze the structure, roles, and institutional rules of the Farmers Group of Karya Tani Mandiri and the Farmers Group of Karya Bakti in the Forest Management Unit of Batutegi, Indonesia. Data collection was carried out using interviews, observations, and literature studies. The data that has been collected is then analyzed using a Likert scale. The results showed that Farmers Group of Karya Bakti in terms of structure, roles, and complete game rules compared to Farmers Group Karya Tani Mandiri. This is because the Farmers Group of Karya Tani Mandiri at the time in the field did not have Memorandum of Association/Article of Association, Decree of the Regent, institution’s structure, the role of the structure, but the facts in the field Farmers Group of Karya Bakti violated the rules of the game in the Memorandum of Association/Article of Association, namely cutting down trees for personal gain. In forest areas, the application of the game rules to the institution's performance of the Farmers Group of Karya Tani Mandiri and the Farmers Group of Karya Bakti needs to be improved so that forest management can be sustainable by understanding and obeying the rules of the game that apply.

Abstract

Teak (Tectona grandis L.f.) is a plant that produces raw materials for the wood industry, which is very popular due to its high quality and selling value. Procurement of teak seeds can be done in two ways: generatively and vegetatively. One problem in cultivating this plant is the inhibition of seed germination due to dormancy. Teak roots experience physical inactivity, namely tough skin. One technique that can be used to break seed dormancy is through chemical treatment. This study aims to determine the concentration of sulfuric acid (H2SO4) and the appropriate soaking time to break the teak seeds dormancy. This research was conducted for two months in the Permanent Nursery of the Department of Forestry, State Agricultural Polytechnic of Kupang, from 15 November 2022 until 15 January 2023. This study used a Completely Randomized Design (CRD) with two factors. The first factor was the concentration of a sulfuric acid solution (control: K0, 75% H2SO4: K1, 80% H2SO4: K2, and 85% H2SO4: K3). The second factor was the soaking time (T1: 45 minutes, T2: 50 minutes, and T3: 55 minutes). The two factors was combined to produce 12 treatment combinations as a whole. Each treatment was repeated three times and used ten seeds, so the total seeds used were 360 seeds. The results showed that there was an interaction between the concentration of sulfuric acid solution (H2SO4) with soaking time length, where the combination of 75% sulfuric acid (H2SO4) concentration and 45 minutes of soaking time gave higher results than other treatments, so it can be said that this combination is better at breaking teak seed dormancy.
