The greater the damage of residual trees to be indicator the less effective the activity. This study aims to determine the damage of residual trees caused by harvesting in the logged-over areas using the ISCP silvicultural system. The study used a research plot measuring 40 m x 240 m (0.96 ha) with 5 replications. Each research plot was consisted of 24 sub plots each for the trees, pole, sapling and seedling levels. Sample felled trees were determined as many as 30 trees. The results showed that the average damage caused by harvesting of 1 tree was 6.46 seedlings/ha; 7.17 saplings/ha; 2.13 poles/ha and 2.25 trees/ha. In general, the damage to residual trees due to felling was 11.28% for seedlings; 11.56% for saplings, 12.14% for poles and 11.8% for trees. The level of damage to seedlings, saplings and poles were in the medium category, while the level of damage to the tree level was in the low category.

The aim of this experiment looking for morpho-physiological characteristics of patchouli varieties adaptive to drought stress condition. The experiment with A Randomized Completely Design with four replicates was used in the trial. Five varieties of patchouli namely Aceh Merah, Lhokseumawe,Tapak Tuan, Sidikalang and Girilaya were transplanted into 30 x 15 x 90 cm wood pot and treated with less water to initiate drought stress after transplanted, all pots were saturated with water (until 100% field capacity), and then treated with no<br>water addition up to 120 days after transplanting (DAT). Parameters observed were: growth and production biomass and proline content in leaf. The results showed that the highest growth and biomass production components were performed by Girilaya and<br>followed by Tapak Tuan varieties. While Sidikalang variety was the lowest in productivity. Maximum length of root, fresh weight of root, and proline content in leaf were also found at Girilaya and followed by Tapak Tuan. Data collection on the growth, production, and morpho-physiological characteristics in relation to adaptation level to drought stress indicated that Girilaya, a Java patchouli group (Pogostemon haeyanus Benth), was the most tolerant among varieties tested.

This research was conducted at the green house of the Indonesian Mycorrhizal Association (AMI) Southeast Sulawesi branch for 4 months (March-July 2019). The study used a factorial randomized block design (CRD) with two factors being tested, the first factors including no AMF inoculation, using Claroideoglomus etunicatum and Septoglomus constrictum which were given 10 grams each. The second factor included watering every day, every two days and every three days, with three replications and three crop units. The results showed that the treatment combination of AMF type S. constrictum with daily watering intervals increased P nutrient levels on the shoot and root, while three days watering intervals increased Mn uptake on the shoot. The combination of AMF treatment for C. etunicatum and daily watering intervals increased the Mn level of the roots and the two days watering interval increased the P uptake on the shoots and roots. The best treatment was a combination of AMF type C. etunicatum and two days watering intervals which effectively increased P uptake of the shoot. Independently, AMF treatment for S. constrictum and two days watering interval were effective in increasing the levels and P nutrients uptake on the shoot.
