Abstract

This research entitled "Age Relationship with Carbon Dioxide Stock of Duku Tree (Lansium parasiticum) in Kalikajar Village, Kaligondang District, Purbalingga Regency". The puspoe of this research are: 1) Knowing the effect of stand age on the amount of carbon dioxide stock stored in duku stands (Lansium parasiticum) in Kalikajar Village, Kaligondang District, Purbalingga Regency. 2) Knowing the age of duku plants (Lansium parasiticum) in Kalikajar Village, Kaligondang District, Purbalingga Regency which has the most potential carbon dioxide stock. The research used survey method by determining tree biomass using stratified random sampling. The strata used is the age of duku plants. Each age strata is taken 3 trees to measure its diameter. The land area is divided by the planting distance to get the results of plant density in that location. Measurement of stand stem diameter is carried out on stand stems at the researchers' chest height (at breast height or dbh). The measuring tape is wrapped around the stand stems in a parallel position for all directions so that the data obtained is the circumference or convolution of the stem (circumference of the stem = 2πr). Age, biomass, and carbon stock data were analyzed using variance analysis (Anova), while the relationship between biomass and carbon stock was analyzed using Pearson correlation and regression analysis. The regression analysis between age and carbon dioxide stock shows an exponential pattern. The lowest corbon dioxide stock of the duku plant is found in the age group <5 years, which is 9.54 tons/ha, while the largest carbon dioxide stock of the duku tree is in the age group > 30 years (40 years) which is 74.89 tons/ha. Thus, this study has not yet gotten the most optimal tree age in storing carbon dioxide. Therefore it is necessary to do research on duku trees that are older than 40 years.

Abstract

Beach is home to the richest ecosystems in the world and many components of the vegetation that store large amounts of carbon stock. Carbon compounds in the atmosphere are absorbed and metabolized. The metabolic products are stored in tree biomass. Cemara Sewu Beach is one of the beach that has a relatively large amount of stored carbon potential. The purpose of this study was to determine the carbon stored in several types of trees at Cemara Sewu Beach. The method used in this study is a survey method with purposive sampling using without destroying. The sampling of Australian pine tree stands is grouped into certain diameter class. The coastal area was made into three research stations and each study was made into 5 replicated plots measuring 20 m x 20 m and placed on a transect line with a distance of 5 meters each. All of the Australian pine were plotted as samples. The main parameters observed were tree density, trunk diameter and the number of individuals for each tree species were calculated. The results of the research on the diameter class of Australian pine greatly affect the presence of biomass and carbon stock. The results obtained that carbon stocks in diameter class 15-20 store 74,914 ton.ha-1, diameter class 21-25 as many as 164,599 ton.ha-1, diameter class 26-30 as many as 270,372 ton.ha-1, diameter class 31-35 store stocks carbon 462,478 ton.ha- 1 and in the diameter class 36-40 store as much as 462,478 ton.ha-1. The larger the class diameter, the greater the carbon stock produced. The diameter class of Australian pine stands has a relationship between biomass and carbon stock, and has an exponential relationship

Abstract

Understorey plant is a type of basic vegetation under forest stands except for saplings. Understorey vegetation includes grasses, herbs, shrubs, and ferns. The presence of understorey vegetation can be used as an indicator of forest conditions and is expected to reduce disturbances to the forest. The purpose of this research is to determine the diversity and the dominance of understorey species under the pinewood stands based on pine ages in RPH Sempor, BKPH North Gombong. This research was conducted using a survey method and systematic sampling techniques at two different age groups pinewood forest of RPH Sempor, BKPH North Gombong. The result showed that the total understorey species found were 34 species from 21 families. The understorey species number found at the 25 years of pine forest was 22 species found and at the 45 years, there were 17 species. Based on the research that has been done, it can be concluded that the younger the age of pine stand, the more understorey species number. Evenness of the understorey species at two different ages of pine stand in RPH Sempor is evenly distributed, so there are no dominant species. The physicochemical factors measurement result showed that the canopy cover affected the temperature and humidity level, thus affecting the number of understorey individuals and the species number in each stand.

Abstract

A phenomenon in which a temperature difference between the present and the past exists is called Global Warming. Today's temperature is relatively higher than before. This temperature change causes climate change. Climate change due to global warming has caused changes in various areas of life, including plants. One of the plants' most influential physiological processes is the phenology of flower patterns. Studies on the effects of climate change caused by global warming on organisms can be represented by altitude gradients. This study aimed to determine the effect of altitude on the phenology of flower development in Yard long beans (Vigna unguiculata subsp. Cylindrica (L.) Verdc.). The parameters observed were the vegetative and phenology of plant development, namely the flowering age (Scale N days after planting), the number of flowers per plant, and flower size. The research was conducted in six places with different altitudes, ± 50 masl, ± 200 masl, ± 400 masl, ±600 masl, ± 800 masl, and ±1,000 masl. The research period lasted for three months.  The research was conducted using the survey method. The independent variable used was the difference in elevation gradient, while the dependent variable was the cultivation pattern of yard-long beans.  The sampling technique is purposive sampling. The data obtained were analyzed using One-Way analysis of variance (ANOVA) and regression correlation analysis. The analysis showed that altitude affected flowering time, number of flowers, and flower size. Yard-long beans grow and develop optimally at 50-400 meters above sea level.
