POLA SEBARAN POPULASI AREN (Arenga pinnata) BERDASARKAN KELAS PERTUMBUHAN DI DESA SANGTANDUNG KECAMATAN WALENRANG UTARA KABUPATEN LUWU
Get PDFAren (Arenga pinnata) is a type of palm where almost all of its parts can be utilized, starting from the roots, stems, leaves, flowers, and fruit. Based on the growth rate of sugar palm can show the pattern of distribution using the Morisita index formula. The distribution pattern is a series that has settled on a symptom itself between individuals, which can be divided into three, namely uniform (regular), random (random), and clustered (clustered). This study aims to determine the distribution pattern of the sugar palm (Arenga pinnata) population based on the growth rate. This research was carried out in Sangtandung Village in July 2021. The data collection method used a purposive sampling technique by placing plots in an area with a sugar palm population following the river body 200 meters long. The distribution pattern of sugar palm based on the growth rate was analyzed using the Morisita index formula. Based on the Morishita index, the study results obtained a pattern of palm sugar distribution based on the growth rate, namely seedlings, saplings, trees with clustered patterns, and poles with uniform patterns
PERBANDINGAN STRUKTUR POPULASI TIGA JENIS KELOMPOK MERANTI (Vatica flovirens, Vatica rassak dan Hopea celebica) di KAWASAN HUTAN FARUHUMPENAI DAN DANAU MATANO
No full textPerambahan dan pembakaran sebagai salah satu praktek pembukaan lahan untuk pertanian intensive yang marak dilakukan adalah perkebunan merica. Hal ini menyebabkan keberadaan populasi jenis endemik Hopea spp. dan Vatica spp. menjadi terancam di habitat alaminya. Tujuan dari kajian ini adalah mengetahui Struktur Populasi dari jenis Rode (Vatica flavovirens), Dama’ dere (Vatica rassak) dan Mata Kucing (Hopea celebica) pada habitat alaminya di Kawasa Hutan Faruhumpenai. Hasil penelitian ini menunjukkan jumlah populasi terbesar adalah pada tingkat semai untuk jenis Vatica flavovirens pada blok I, II dan IV. Kerapatan dan jumlah individu terbanyak yaitu berada pada blok I dengan total kerapatan sebesar 1.910 individu/Ha (535 invidu). Pada blok II, kerapatan semai sebesar 382,14 individu/Ha (107 individu), sedangkan pada blok IV terjadi penurunan yang sangat signifikan, kerapatan hanya 62,5 individu/Ha (5 individu). Hal ini menunjukan bahwa terjadi gangguan pada habitat alaminya, dimana terjadi perambahan dan kebakaran yang menyebabkan banyak semai atau anakan mati seketika. Oleh karena itu, perlu upaya perlindungan dan pelestarian dua jenis kayu endemik secara partisipatif melibatkan dan bekerjasama dengan multistakeholder utamanya masyarakat desa. yang berada di sekitar Kawasan Hutan Faruhumpenai.

KUALITAS TEGAKAN BENIH LOKAL DI HUTAN LINDUNG KAB. LUWU UTARA
No full textInformation regarding the potential and dominance of local plant species in the Sassa Village Protection Forest, North Luwu Regency is still limited. In fact, there are fewer and fewer local plant species that are used by the community, this is indicated by the difficulty of obtaining local plant seed sources. This difficulty is due to the lack of local parent plants in this area, for this reason it is necessary to study the potential of local plants and the selection of parent trees for local plant seed sources. The research method by collecting data was carried out using exploratory techniques with the transect method, then the parent tree that had been determined as a seed source stand that had met the criteria as a parent tree was given a coordinate point. Then the scoring was carried out on tree height (T), tree diameter (D), branch-free height (Tbc), trunk straightness (KB), trunk surface (PB) and tree health condition (KK). The results of this study obtained 16 types of plants with the highest T score of 20, 16 species of plants with the highest D score of 30, 33 species that had the highest Tbc score of 15, and 3 types of plants that had the highest KB+PB+KK score of 20. There were 18 species with a total score of >60 that met the highest criteria as well as from the various genotypic characteristics that had been observed.Â

Get PDFSulawesi island is a unique island among other islands in Indonesia. This research aims to find out the social interaction behaviour of Dare Black Monkey (Macaca maura) in the Lejja natural tourism park. This animal is an endemic in Sulawesi island, located in South Sulawesi Province and categorixed as an endangered species by the IUCN, therefore its existence must be protected. The method was used field observation and focal animal sampling. The object was detremined in 15 Macaca maura based on age and sexuality in a group.Social interaction behaviour was recorded, namely the behavior of playing, grooming, coitus, conflict. Based on the results that the high social behaviour frequency of playing activity was owned by the young male (72 times) and the children (56 times), as well as grooming by young male and children have the highest frequency (31 times). Frequency of coitus and agonistic behaviours was owned by adult male with 14 times and 5 times respectively.However, the longest time proportion of playing was used by children with 10.602 second (62,01%),while the total and time percentage of coitus have the lowest value (240 second or 2,11% and 300 second or 2,58% perspectively) by adult ages
The Regeneration Potential of Kasa (Castanopsis acuminatissima Blume) in Kalaena Nature Reserve, East Luwu Regency
Get PDFKasa is one of the important species among 120 species in the genus Castanopsis (Fagaceae), which thrives in secondary and primary lowland forest areas up to 1000 m above sea level. This plant species exhibits tolerance to full sunlight. The objective of this study is to assess the regeneration potential of Kasa (Castanopsis acuminatissima Blume) in the Kalaena Nature Reserve, Indonesia. The research plots consisted of two 50 m x 50 m plots, with a nested 10 m x 10 m subplot placed using purposive sampling. The findings regarding the regeneration potential of Kasa in the Kalaena Nature Reserve revealed varying numbers of seedlings, saplings, poles, and trees. The regeneration potential of Kasa is influenced by the growth stages of seedlings and trees. During the seedling phase, the regeneration potential of Kasa is classified as very good. However, the density of trees, although in the productive category, is low due to environmental factors and the characteristics of the parent tree. Conversely, the sapling and pole phases exhibit very poor regeneration potential. In plot 1, there were 1964 individual seedlings, 6 individual saplings, 4 individual poles, and 21 individual trees. Meanwhile, plot 2 recorded 844 individual seedlings, 5 individual saplings, 1 individual pole, and 18 individual trees. The growth of Kasa in both plots displayed a clustered pattern
