Abstract

Growth models can provide information on how the tree grows with age, and can be used to predict the level of timber production. This study aims to find the growth model of height (H) and diameter (Dbh) and determine the maximum volume cycle of Eucalyptus sp. in PT. XYZ. Samples were taken in various compartments with ages of 18 months, 30 months 42 months and 54 months. The total sample of 64 plots was divided into 48 plots for model development and 16 plots for model validation. The four types of models analyzed were Linear, Logarithmic, Inverse and S models. Modeling was done through regression analysis. Model acceptance criteria were significant in F test, R2 value and SeR, while model validation criteria used RMSE, SR, SA and Bias values. The best growth model in this study for both Height and Dbh was the S model with the equations Height=e^(3.0355 - 1.3525/x) and DBH=e^(2.6491 - 1.2843/x). The maximum volume cycle was achieved at the age of 4.5 years with a volume of 172.7284 m3/ha and a Mean Annual Increament (MAI) value of 38.3841 m3/ha/year.

Abstract

Sengon is one of main raw material on wood industry and can be harvested at 5 years.  Another planted at widodomartani ngemplak sleman yogyakarta indonesia with Regosol soil. The aims research were to determine the growth at five years. Planting is done with a distance of 2 x 2 m in the planting hole measuring long and wide with same each 30 cm, 40 cm and 50 cm. The planting hole each used 2 kg and 3 kg compost. The growth data (height and diameter) was taken in each treatment (6 treatments) and each treatment by three repeated. The  data obtained  were analyzed by Anova and if there were significant  differences in factors, followed by LSD test. The analysis showed that the treatment is significant affect to the heigh. The growth rate of Sengon at five years planted is plant height 19.19 m and 18.25 cm diameter. The planting holes 50 cm x 50 cm x 50 cm and 2 kg compost giving optimal result. The best growth of  Sengon treatment is planting 50 cm x 50 cm x 50 cm and 2 kg compost with plant height 24 m and 31.02 cm diameter at the five years plants.

Abstract

ABSTRACT The concept of sustainable tourism which prioritizes environmental, natural and cultural preservation is known as "ecotourism". Mangroves are a unique ecosystem that has a lot of diversity and beauty. The presence of mangrove ecotourism in the community can have a positive impact and play an important role in ecosystem life. Therefore, community perception, motivation and participation are important factors that determine the existence of ecotourism in an area. Positive perceptions can encourage active community participation in conservation activities, environmental education and ecotourism development. On the other hand, negative perceptions or lack of understanding can become obstacles in environmental conservation efforts. This research was carried out for 3 months in the Kano Maritim Baros Mangrove Ecotourism area, Bantul Regency, Special Region of Yogyakarta. This research aims to see and analyze the perceptions, motivations and participation of communities involved in mangrove ecotourism in Kano Maritim Baros. To process respondent data, this research uses a Likert scale and correlation analysis. The number of respondents in this study was fifty. The results of this study show that the three variables tested for correlation do not have a significant correlation with each other. Apart from that, the perception, motivation and involvement of the community towards the existence of the Kano Maritim Baros mangrove ecotourism is categorized as "Good".

Abstract

This research aims to determine the influence of organic stimulants and stimulant concentrations on pine resin production, to obtain alternative stimulants that are safe for the environment and can also increase pine resin production. The research design used a Completely Randomized Design (CRD), with a factorial experiment consisting of two factors, namely the organic stimulant type factor which consisted of 3 levels, namely the stimulant extract of shallots, ginger and galangal and the stimulant concentration, which consisted of 3 levels, namely 100% concentration. , 75% and 50% plus control, so there are 9 treatment combinations. Replication was carried out 6 times so that 54 tree samples were obtained plus 6 control trees, or a total of 60 tree samples. The results of the research showed that the average production of pine resin in the stimulant treatment types of onion, ginger, galangal and control extracts was 76, 28 grams, 76.28 grams, 140.06 grams and 21.23 grams, respectively. The results of the variance analysis show that the type of stimulant shows a very real influence, while the concentration of the organic stimulant shows an insignificant influence. Further test results showed that the organic stimulant galangal extract had a significant difference from the organic stimulants of ginger and shallots, while the organic stimulants of shallots and ginger showed no significant differences. The research results also showed that the sap production of the onion and ginger extract stimulant treatment showed sap production that was not significantly different from the control, however, the galangal extract stimulant treatment showed a significant difference.

Abstract

Anthocephalus cadamba Miq., is a type of tree from South and Southeast Asia which is currently widely cultivated by the community. Jabon has various uses such as block board and particle board. Apart from that, this plant is also known as a fast growing plant. Jabon farmers have their own way of caring for their plants, on of which is plant spacing. The goal of this research was to ascertain the impact of planting distance on survival rate and growth (height and diameter) of 1 year old Jabon plants in Temanggung Regency, Central Java. Data collection was carried out by taking 50 samples in each field consisting of 2x2 m, 3x3 m, and 4x4 m spread across 3 villages in Temanggung Regency. The replicates used were individual Jabon plants. Data from the research results were analysed using by analysis of variance, and tested further using the LSD test. The research results showed that land with a planting space of 3x3 m had a higher percentage of jabon plants than the land with a planting space of 2x2 m and 4x4 m, namely 71%. Land with a planting space of 2x2 m produce a better average height and diameter of jabon plants than of 3x3 m and 4x4 m, namely 1,39 m for height and 1,97 cm for diameter respectively.
