Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh media (topsoil dan cocopeat) dan perlakuan pada benih (kontrol, perendaman, peretakan cangkang dan pengupasan cangkang) terhadap pertumbuhan benih nyamplung dari Pulau Talise hingga umur 3 bulan. Penelitian menggunakan rancangan acak lengkap dengan parameter pengamatan tinggi, diameter, kekokohan semai, dan indeks mutu bibit.  Hasil penelitian diketahui bahwa karakter pertumbuhan nyamplung dipengaruhi oleh media dan penanganan benih. Media cocopeat akan meningkatkan viabilitas namun menurunkan tingkat pertumbuhan, sehingga diperlukan penyapihan dengan media yang lebih subur saat penyapihan. Penanganan benih dengan pengupasan cangkang memiliki pengaruh paling baik terhadap pertumbuhan dan kualitas bibit. Berdasarkan penelitian ini, pembibitan nyamplung diperlukan bedeng tabur skarifikasi dengan media cocopeat dan perlakuan pengupasan cangkang sebelum di sapih.

Abstract

There are 14805.14 ha of North Sulawesi coastal ecosystems that has been damaged. Baringtonia asiatica Kurz (Keben) is one type of coastal plants that can be used to protect coastal areas . Unfortunately, the propagation technique of Keben was not widely studied. This study aims to determine the characters of seedlings produced from the stumps of seed germination. The research used Complete Random Design with nine treatments, consisting of combination betwen three levels of root length (0 cm, 5 cm and 10 cm), and three levels of the stems length (5 cm, 15 cm and 30 cm). Parameters for analysis include percent of success, growth and quality index. The results show that root length and stem length factors significantly affect the height and robustness value. Treatment of root length of 10 cm and 5 cm rods allegedly produces the most excellent quality with the survival rates 93%, height 10.3 cm, diameter 1.08 cm, robustness value 2.03 and index of seed quality 1.35. Based on regulation of land rehabilitation, the height of 10 weeks stump have not qualified yet.

Abstract

This study purposes to compare the effectiveness of bio-insecticides made from papaya leaf extract, and chilli pepper in several different doses to reduce pest attack on white oyster mushroom (Pleurotus ostreatus). Experiments conducted on oyster mushrooms that are fruitful with 3 formula are formula 1 (papaya and water), Formula 2 (papaya leaves, chili pepper, and water), and the formula 3 (chili pepper and water). Parameters observed were the fallen fruit, harvest weight, fruit diameter, the number of dead pests. The results concluded that the formula has a significant effect on all parameters. Formula 2 has the highest level of effectiveness of insecticides can reduce the fallen fruit to 84 %, have twice yields and 1.3 times bigger diameter than control crop yields. Formula 2 has the composition of papaya leaf extract and chili pepper (1:1:2)

Abstract

Fungi have a vital role in ecological processes, as an indicator of health of an ecosystem, it is not only has the potency for medicine and food but also variety of unexplored potential. Arboretum has high potential for biological conservation including fungi species, so information on its diversity and potency are very important for the basis of its management. The purpose of this research was to explore the diversity of species and the potential of macroscopic fungi in the BP2LHK Manado Arboretum. Observations were conducted 8 times in May, June, and September 2016 using a cruise and an opportunistic method. The infromation of growth media, light intensity, and temperature were collected as a supporting data. The result showed that arboretum stored 48 species of macroscopic fungi with different characteristics. 39 species were identified, divided into 2 divisions, 6 classes, 9 orders, and 17 families, while the remaining 9 species were unidentified.. The results showed that the diversity of macroscopic species habitat were dominated by 31 species grown on necromass, 11 species grown on litter and 6 species grown on soil. Based on its potential, there were 2 species of toxic fungi, 1 species of edible and medicinal fungus, 2 species of edible fungi, 5 species with medicinal fungi, 19 species were not edible, and 19 species with unknown benefits.
