Abstract

Mount Burangrang Nature Reserve is a tropical mountain area with a total width up to 2.700 hectares and is located in Subang and Purwakarta regencies. Mount Burangrang Nature Reserve functions as a protector for the diversity of flora and fauna. However, the protected area is still not spared from the threats which come from outside or within the area. One of the threats is the existence of invasive alien species. It is an alien plant species that is introduced into a non-original ecosystem and brings effects on the ecological field. This study aimed to find out the diversity and distribution of invasive alien species at Mount Burangrang Nature Reserve, Subang Regency, West Jawa in Januari until march 2021. The square transect was chosen as a research method. According to the results, there were seven species of invasive alien plants with a total number of 244 individuals. The diversity index of invasive alien plant species at Mount Burangrang Nature Reserve was categorized as low with a range of values between 0,204-0.819. Meanwhile, the distribution was divided into clumped which owned by six species, Austroeupatoriuminulifolium, Chromolaena odorata, Ageratina Riparia, Calliandracalothyrsus, Musa acuminata, dan Maesopsis eminii and uniform distribution which only one species had Clidemia hirta.

Abstract

AbstractThe annual production of cajuput oil in Indonesia can reach 88,607 tons. This has implications on the accumulation of the waste. One of the efforts to reduce the amount of cajuput waste is to use this waste as organic fertilizer. This study aimed to determine the content of C, N, P, and K of cajuput leaf waste fertilizer and their effect on the growth and development of tomato plants (Lycopersicum esculentum L.). This study used a Completely Randomized Design (CRD) with P0+ treatment (EM4 fertilizer); P0- (no fertilizer); and treatment with the ratio (%) of cajuput leaf waste fertilizer: chicken manure, including P1 (100:0); P2 (75:25); P3(50:50); P4 (25:75); P5(0:100). The results showed that P2 treatment had a higher content of N-total (2.82%) and C-Organic (44.28%) with a C/N ratio of 15.70%, directly proportional to the results of the best vegetative growth response, indicated by a plant height of 125.75 cm, stem diameter 0.665 cm, and the 15.75 number of leaves. The P2 treatment was considered to have the best for tomato plant development by producing fruit sizes (diameter; length) up to 3.40 cm; 3.49 cm with a weight of 20 g.AbstrakProduksi tahunan minyak kayu putih di Indonesia bisa mencapai 88.607 ton. Hal ini berimplikasi pada penumpukan sampah. Salah satu upaya untuk mengurangi jumlah limbah daun kayu putih adalah dengan memanfaatkan limbah tersebut sebagai pupuk organik. Penelitian ini bertujuan untuk mengetahui kandungan C, N, P, dan K pupuk limbah daun kayu putih serta pengaruhnya terhadap pertumbuhan dan perkembangan tanaman tomat (Lycopersicum esculentum L.). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) Perlakuan P0+ (pupuk EM4); P0- (tanpa pupuk); dan perlakuan dengan perbandingan (%) pupuk limbah daun kayu putih dengan kotoran ayam, di antaranya P1 (100:0); P2 (75:25); P3 (50:50); P4 (25:75); P5 (0:100). Hasil penelitian menunjukkan bahwa perlakuan P2 memiliki kandungan N-total (2,82%) dan C-Organik (44,28%) yang lebih tinggi dengan rasio C/N 15,70%, berbanding lurus dengan hasil respon pertumbuhan vegetatif terbaik yang ditunjukkan oleh tinggi tanaman 125,75 cm, diameter batang 0,665 cm dan jumlah daun 15,75. Perlakuan P2 dinilai paling baik untuk perkembangan tanaman tomat dengan menghasilkan ukuran buah (diameter; panjang) hingga 3,40 cm; 3,49 cm dengan berat 20 g.
