Mangrove at Bintuni bay offers various services to indigenous communities from ecology, social, and economic. Mangrove also could be harvested accordingly to optimize contributions to indigenous communities welfares. This paper highlights implementation of customary right compensation (CRC), and Forest Villages Development programs (FVDP) of mangrove company at Bintuni Bay, Papua Barat. Company reports and documents related to CRC and FVDP from 1988 to June 2013 were reviewed and analyzed. Field works were conducted to examine the implementation of both programs at four villages of two districts. Sustained mangrove harvest for chipwood production in Bintuni bay for more than 25 years is the most outstanding achievement of mangrove utilization and management in Indonesia. Huge amount of expenditure have been spent out, and given to indigenous communities through the CRC and FVDP programs, respectively. These cover from economic, social, and environmental related programs, manufactured public facilities, scholarships, and others. However, the indigenous communities are remained poor, and failed of being self-sufficient community. It clearly impresses that the main goals to improve the welfare, prosperity of indigenous people are considerable failed. It is presumably that social culture systems, and subsistence agriculture practices contribute to the failing these programs. Mostly, forest communities in Papua are practicing subsistence agriculture, hunting, heavily relying on their surrounding natural resources, and spending all their cash or money instantly for consumption, not for saving, investments or even productive activities. Therefore, several program could be initiated to improve in achieving the CRC and FVDP missions, such as building capacity, providing counselors and strengthen local community governance, which could accelerate of being self-reliant community.

Protected forests have drawn international attention. This research aims to determine scenarios of land-use change in Protected Forest of Wosi Rendani (PFWR). The study was conducted using land evaluation approach to land unit, determination and alternative land use change, based on the potential and the level of threat for PFWR. The results showed that PFWR should remain as a protected forest although the total score of forest modeling was 130. This forest serves to protect soil, water, and danger from floods and landslides. This region has springs, caves, and waterfalls, which can be further developed into eco-tourism and environmental services. As a city forest, PFWR makes Manokwari's weather cooler, enhances the quality of air, reduces environmental pollution, and adds catchment areas. As a community forest, PFWR has forest plants, agricultural crops and fruits, in which people are only allowed to take flowers, fruits, and seeds they have planted. As a buffer zone, PFWR serves as a buffer to reduce population pressures on the forest area or village surrounding the area with high interaction by integrating conservation and economic interests of the surrounding community. As cultivation and settlement, PFWR has three settlements, namely Soribo, Kentestar, and Ipingoisi, 4 settlements outside PFWR namely Tanah Merah Indah, Ajoi, Buton, Mako Brimob, as well as plots of land owned by developers such as Bank Arfindo, Lumintu, Irman Jaya, and Suntari. The final scenario of the land use change in PFWR depends on the policy of local and central government.

Antifeedant activities of berberine isolated from the chloroform fraction of Tali kuning (Tinospora dissitiflora Diels) were evaluated against two subterranean termites, Coptotermes formosanus Shiraki and Reticulitermes speratus Kolbe, respectively. The chloroform fraction of methanol extracts of Tali kuning and authentic berberine chloride were used for comparison. Three replicates and levels of concentrations, 12.5, 25, and 50 mg/ml, respectively, were employed. Filtepapers treated with three chemical substances were used to evaluate the mass losses of the filter paper consumed by the termites, and filter papers treated only with MeOH were used for control. Mass loss (MS), termite mortality (TM) and antifeedant index (AFI) were used to determine the antifeedant variables. The results indicated that regardless of three chemical substances tested, the MS recorded from C. formosanus Shiraki were 2.87 times higher than those of R. speratus Kolbe, and among three levels concentration, 50 mg/ml gave the lowest MS (2.13%). Authentic berberine chloride gave the highest TM (99%), followed by chloroform fraction (88%) and berberine (73%). Interestingly, all antifeedant variables employed in this study gave AFI values less than 20%, indicating significant feeding deterrent activity against two subterranean termites.

Two different approaches have been used to determine the bioactive compounds in the medicinal plant of Tali kuning (Tinospora dissitiflora Diels). Firstly, the conventional approach using column chromatography (CC), and preparative thin layer chromatography (PLC) eluted with benzene:ethyl acetate: formic acid (5:4:1, and 5:4:2, respectively), followed by CC eluted with benzene:methanol (3:2) were used to separate and isolate berberine from the chloroform fraction of Tali kuning. Structural elucidations of the isolated compounds were conducted using nuclear magnetic resonance (NMR) and mass spectrometry (MS). Secondly, a rapid and simple approach use the integrated intensities of proton signals for H-13 and H-8 of berberine on 1H-NMR spectra, then the qualitative and quantitative determination of berberine in Tali kuning can be achieved directly from the crude extracts using 1H-NMR. The proton signals for H-13 and H-8 of berberine on 1H-NMR spectra, which appeared at empty regions as singlet, and without interference from the other signals, were available for qualitative determination of berberine. Whereas, the integrated intensity of proton signal for H-13 on 1H-NMR spectrum was used for quantitative determination of berberine. Berberine content of Tali kuning was calculated manually based on the integrated intensity of proton H-13 from the authentic berberine chloride, which was 18.6 mg/g based on the weight of air-dried wood meal. This berberine content was comparable to that (22.78 mg/g) of Amur corktree (Phellodendron amurense Rupr), which is widely acknowledged for good producer of berberine.

The aims of this study were to evaluate the main compounds and the effect of M. leucadendron, C. odorata and P. cablin essential oil odors on human physiological responses. The chemical compounds of essential oils in this study were analyzed by gas chromatography-mass spectrometry (GC-MS) and the physiological effects of essential oils on human were analyzed via the sense of smell olfactory system. Physiological parameters of systolic blood pressure, diastolic blood pressure, pulse rate, stress index, and brain wave were recorded before and after sniffing essential oils. The result shows that the main compound of M. leucadendron, C. odorata, and P. cablin is 1,8-cineole, Caryophyllene and Patchouli Alcohol, respectively. Our results demonstrated that M. leucadendron and C. odorata oil odors possessed sedative effect and P. cablin oil odor had tendency to contain stimulating effect on human physiologies.

The biodiversity richness of tropical forests in Papua provides substantial livelihood necessities for most forest people. This includes Non-Timber Forest Products (NTFPs), under-valued, neglected, or minor forest commodities that play a key role for the entire livelihood of the forest people. This paper highlights the diversity of NTFP marketed by the local people of Papua at traditional markets in Manokwari, West Papua. Data were collected from twenty respondents selected randomly from two local markets at Manokwari and field visits to surrounding (primary or secondary) forests, and analyzed using simple statistical analysis. The result indicates that 29 NTFPs commodities were on the market, and grouped into vegetables (9), food (4), fruit (7), medicinal herbs (4), tools (3) and addictive material (2). These commodities give alternative incomes, create unskilled jobs to the female-forest dwellers at Manokwari, and provide daily fresh vegetables and nutritious products for local customers. The marketed NTFPs are harvested from surrounding primary or secondary forest areas of Manokwari. Banana is the most favorable commodity in high demand either serving as food or fruit. Sago (Metroxylon spp.) is the only commodity supplied from other areas out of Manokwari, mainly from Wondama, Biak, Jayapura, and Serui. Annual events of Christmas and New Year create the highest demand for sago processed to papeda, that represent cultural or heritage food for most of the Papuanese family gatherings. Cultivation of these NTFPs has to be seriously considered for sustainable harvest due to the current extensive harvesting from the nature which will deplete the resources if no intensive cultivation carried out. To sustain availability of fresh daily needs, and provide alternative income to local people, local government, forest institutions, universities, non government organizations, and motivators need to work together to gain added value and secure sustainable supply of those NTFPs.

Tali kuning (Tinospora dissitifloraÂ Diels) is medicinal plant endemic to New Guinea, widely used to prevent and cure malaria symptoms in Papua. In utilizing this plant, they harvest directly from the forest without planting. If this continue, it will become extinct. This research, therefore, is to investigate responds of cutting stem of Tali kuning planted on four media, soil, sand, and forest litter and their combinations. Variables consist of growing cuttings, callus cuttings, shoots cuttings, rooted cuttings and express in percent. The cuttings produce callus, shoots, and leaf are expressed in days. Numbers of leaf, roots, and tendrils (shoots enlengthen) are counted in sheets. Length of tendrils and roots are measured in cm. The results indicate that Tali kuning can be planted using cutting stem in the media tested. Soil media resulted the highest percentage of growing cuttings, callus, shoots, and rooted. Callus is produced at 16 days at average, shoots at 21 days, and leaf at 26 days. Each media produces a single tendril at average 27.44 cm in length, 15 roots with 5.84 cm long, and leaf of 8 sheets. Tukey test indicates that four planting media did not result significantly different for growth variable, except for the length of roots.Key words:Â Growth, cutting stem, Tali kuning, planting media
