Abstract

Population structure is defined as an arrangement of age classes in a population. It is very important to study population structure to determine the status and existence of a population so that efforts can be made to control the population in that habitat. Pine is one of the plants found in the Danau Sari Embun area which has the potential to be used as a learning resource based on local content. The results of data analysis show that the population structure of Pine plants in the Danau Sari Embun area was found to be 0 Ind/2.5 Ha in the pre-reproductive phase, 14 Ind/2.5 Ha in the reproductive phase, 0 Ind/2 Ha in the post-reproductive phase. .5 Ha, so that the shape of the pyramid is in the form of a vase or jug with a disturbed base. Keywods: Population Structure, Pinus merkusii, Danau Sari Embun   Abstrak Struktur populasi didefinisikan sebagai suatu susunan kelas umur dalam suatu populasi. Kajian tentang struktur populasi sangat penting dilakukan untuk mengetahui status dan keberadaan suatu populasi sehingga dapat dilakukan upaya untuk penanggulangan populasi dihabitat tersebut. Pinus adalah salah satu tumbuhan yang terdapat di kawasan Danau Sari embun yang berpotensi dijadikan sebagai sumber belajar berbasis muatan lokal. Hasil analisis data menunjukkan bahwa struktur populasi tumbuhan Pinus di kawasan Danau Sari embun di dapatkan jumlah pada fase pra-reproduktif berjumlah 0 Ind/2,5 Ha, fase reproduktif berjumlah 14 Ind/2,5Ha, fase post-reproduktif berjumlah 0 Ind/2,5Ha, sehingga bentuk piramidanya berbentuk pasu atau kendi dengan dasar terganggu.

Abstract

Population structure is one of the references that can be used to determine the status and existence of a population in a habitat. Kweni mango (Mangifera odorata Griff) is one of the endemic mango species of South Kalimantan. This study aims to examine the population structure of kweni mango (Mangifera odorata Griff) on the banks of the Barito River, SungaiGampa Village, Barito Kuala Regency. The research method applied is total exploration. The results of the study showed that the population structure of kweni mango in the Barito Kula Riverbank area, Sungai Gampa Village has a pyramid shape of a disturbed pitcher with three growth phases, namely pre-reproductive (118.42 ind / km2), reproductive (625 ind / km2), and post-reproductive (111.84 ind / km2). So that kweni mango plants can be categorized as being in a safe or fairly developed condition because they have more than 25 adult individuals in 1 km2.

Abstract

The population structure of plants is a critical area of study in ecology, essential for understanding the dynamics of plant assemblages. Sandoricum koetjape (Burm.f.) Merr, commonly known as kecapi, is a plant species found along the banks of the Barito River in Sungai Gampa Village. This study aims to describe the population structure of kecapi (Sandoricum koetjape (Burm.f.) Merr)   in this riparian area. The research employed the cruise method within an area spanning 3 km in length and 50 meters in width from the riverbank, with population data based on the classification by Odum (1993). The results showed that the population structure consists of 98.68 individuals/km² (pre-reproductive), 171.05 individuals/km² (reproductive), and 26.31 individuals/km² (post-reproductive), forming an urn-shaped pyramid indicative of a disturbed population, however, the kecapi population is considered stable and not in a critical condition, as more than 25 mature individuals were found per square kilometer.
