Abstract

Climate change is likely to lead to adaptations among important crop species. Elevational gradients can be used to illustrate the effects of climate change on crop adaptation patterns. The research aimed to determine adaptation patterns in crop species across an elevational (and therefore temperature and humidity) gradient. A factorial design was applied with two factors within a simple Randomized Complete Block Design, wherein the primary factor was elevation (10 – 1,000 m). Three crop species (long bean, common bean, and winged bean) were used as test species. Growth rate and flower number were used as adaptation parameters. The results indicated that these three cash crop species showed different adaptation patterns. Common bean showed the greatest vegetative growth at approximately 600 m in elevation, long bean at 400 m in elevation, and winged bean at 10 m in elevation. The results of this study indicate that the three tested agricultural crops have different adaptation patterns, and these results was the first finding to be published in Indonesia. For agriculture practices, it can be recommended that planting of these cash crops be adapted to the elevation of the planting area.

Abstract

Salah satu unit pengelolaan Perusahaan Hutan Negara Indonesia (Perhutani) yang mengembangkan hutan jati adalah Kesatuan Pemangku Hutan (KPH) Banyumas Timur. Hutan jati yang dikelola KPH Banyumas Timur terdiri dari berbagai kelompok umur. Umur tegakan berkaitan dengan tutupan tajuk dari pohon di sekitar tumbuhan bawah yang berpengaruh terhadap keanekaragaman tumbuhan bawahnya. Penelitian ini bertujuan untuk menganalisis vegetasi keanekaragaman dan kemerataan jenis tumbuhan bawah pada berbagai umur tegakan Jati (Tectona grandis L.) di KPH Banyumas Timur. Penelitian dilakukan di Hutan jati BKPH Kebasen, KPH Banyumas Timur, dengan tiga kelompok umur tegakan yaitu 16, 20 dan 22 tahun. Hasil penelitian menunjukkan bahwa pada berbagai umur tegakan jati di KPH Banyumas Timur terdapat 34 jenis tumbuhan bawah dari 17 familia. Tegakan jati umur 16 tahun memiliki keragaman tumbuhan tertinggi dengan indek nilai penting tertinggi sebesar 42,77% pada Echinochloa colona (L.) dari familia Poaceae. Keanekaragaman tumbuhan bawah pada tegakan jati dengan umur 16 tahun sebesar 2,12 dengan kemerataan jenis sebesar 0,73. Nilai kesamaan jenis tertinggi sebesar 30,77% dari tegakan jati berumur 20 tahun sedangkan tegakan jati berumur 16 tahun dengan 20 tahun sebesar 25% dan 26,67%. Komposisi dan distribusi serta tinggi rendahnya keanekaragaman tumbuhan bawah pada ketiga tegakan jati umur berbeda, dapat dipengaruhi oleh faktor lingkungan yang terbentuk disekitar tegakan.

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

Mango (Mangifera indica L.) is a tropical fruit that is in demand by many people so that it can be found throughout Indonesia. Mangoes have a wide variety of morphology. This diversity occurs because of crossbreeding, natural selection, human influence, evolution and even environmental influences of each location. The research aims to determine the morphological variation of mango cultivars in Tangerang Regency and to know the relationship of similarities based on morphological characteristics. The research was conducted in Tangerang Regency by survey method, with purposive sampling techniques. The bound variables in this study were types of mango cultivars, while free variables covered the height of the place, temperature, humidity, light and pH of the soil. The observed parameters include the morphological characteristics of stems, leaves, fruits and seeds. Mango sample data is analyzed by descriptive method. Medium to know the relationship of similarities analyzed with MEGA X using UPGMA method. The results of research from four sub-districts in Tangerang district found 14 types of cultivars. The similarity relationship based on 22 morphological characteristics results in phenograms divided into 2 main groups. M. indica 'Madu' with M. indica 'Manalagi' and M. indica 'Khiosaway' with M. indica 'Namdokmai' has the closest relationship with the disimilarity index of 0.182. M. indica L. 'Chokanan' and M. indica L. 'Gedong' have the furthest relationship with the disimilarity index of 0.682.
