“…Masoi dapat digunakan sebagai bahan bangunan (Pratiwi, 2015). Disamping itu, masoi juga digunakan sebagai bahan pewarna campuran untuk pembuatan batik Jawa (Bustanussalam, Susilo, & Nurhidayati, 2014). Berbagai manfaat inilah yang menjadi salah satu penyebab terjadinya eksploitasi berlebih terhadap masoi di hutan alam.…”

Massoi (Cryptocarya massoy) is a plant species producing prominent NTFP in Papua. This species contains massoialacton used as a raw material for food, cosmetic, and pharmaceutical industries. The demand for massoia is high. Meanwhile, supply for the global market is still dominated by massoi from Papua. This condition leads to the over exploitation of massoi in nature. If this condition continues, massoi might be extinct in the future. Until now, the information about the potency of massoi in natural forests is not available yet. Therefore, studies that can depict the existence of massoi in natural forests are still needed. This study is needed to determine massoi's conservation strategies. This study aimed to determine the potency and distribution of massoi in the forest concession of PT. Yotefa Sarana Timber in Teluk Bintuni Regency and PT. Wanakayu Hasilindo in Kaimana Regency. This study applied line plot sampling method. The results showed that the potency of massoi in Teluk Bintuni Regency is higher than that of Kaimana Regency. The potency of massoi in Teluk Bintuni Regency was 1,593 individuals/ha, consisting of seedlings (1,500 individuals/ha) and stakes (93 individuals/ha). Potency of massoi in Kaimana Regency was just around 871 individuals/ha, comprising seedlings (750 individuals/ha), stakes (120 individuals/ha), and tree (1 individual/ha). Massoi at both pole and tree levels is alarming because of harvesting activities conducted by local people. The results also revealed that massoi grows scattered and rarely clustered. Massoi grows at an altitude of 50-500 masl (Teluk Bintuni Regency) and 400-900 masl (Kaimana Regency).

“…Minyak masoyi diperoleh dari proses ekstraksi kulit batang (Suminar, Arifin, & Kemala, 2015) yang pada umumnya dipanen dengan cara menebang pada pohon yang berumur >10 tahun. Ekstrak etilasetat dari kulit kayu masoyi menunjukkan tingkat toksisitas yang sangat tinggi dan nilai IC50 sebesar 44,02 ppm yaitu sebagai antioksidan kuat (Bustanussalam, Haryanto, & Endang, 2014). Berdasarkan Permenhut 35/2007 tentang Hasil hutan bukan kayu (HHBK) disebutkan bahwa tanaman masoyi merupakan komoditi HHBK yang menjadi urusan Departemen Kehutanan.…”

Plantations development in KPH UPTD Boalemo Unit V area should be supported by community readiness and land suitability. This study analyzed the potential of masoyi plantations in the UPTD KPH Boalemo Gorontalo Unit V based on community readiness and land suitability. The level of community readiness was measured through in-depth interviews with key informants. Land suitability analysis was carried out using species matching method on the plant growth requirements of masoyi. Land characteristics were obtained from secondary data, direct field measurements, and soil analysis. The results showed: 1) community readiness is at level seven to nine; Ayuhulalo Village, Bendungan Village, Botumoito Village, and Rumbia Village have the highest community readiness, 2) land suitability is divided into: suitable 15.93%, moderately suitable 53.82%, and 24% unsuitable, 3) an area of 22,644 ha have the potential for development of masoyi plantation because it has a high level of community readiness and land suitabiliy level at moderately suitable, 4) an area of 7,041 ha is a priority area for the development of masoyi because it has a high level of community readiness and land suitability class at suitable, 5) Bendungan Village and Butomoito Village have the best community readiness and land suitability, 6) production forest area is dominated by marginally suitable land; land improvement/ manipulation is needed towards the limiting factors to support successful planting.

Senggugu is reported to contain potent antioxidant compounds. This study aims to determine the antioxidant activity, to isolate and to characterize the structure of antioxidant compounds of methanolic extract of senggugu’s root bark. The ground dried root bark was macerated gradually with n-hexane, ethyl acetate and methanol. The methanol extract was evaluated for the antioxidant activity using DPPH radical scavenging method and its antioxidant activity was compared to rutin (positive control). Isolation of the antioxidant compound was performed using preparative thin layer chromatography over silica gel GF254 eluted with a mixture of ethyl acetate: acetone: formic acid: water (5:3:1:1). The active compound was obtained as needle like crystals and the structure was characterized by spectroscopic methods as kojic acid which has never been reported as a constituent of this plant. Methanol extract showed to have DPPH scavenger activity with the IC50 12.63±0.09μg/mL, weaker than rutin (IC50=3.49±0.006μg/mL). Kojic Acid is a new compound from the methanol extract of senggugu’s root bark which has very strong antioxidant activity.
