Abstract

One of the problems in developing Nyawai plants is the attack of snail pests Achatina fulica (Ferussac, 1821) at seedling level of the plants. Plant damage caused by these pests is quite large and causes seedling death. One of the control efforts that can be done is utilizing biomaterials which have molluscicidal properties (can kill mollusks). This study aimed to determine the toxicity of some extracts of biomaterial to control Achatina fulica (Ferussac, 1821) pests. The research was conducted on a laboratory scale. The study used a factorial random design with 3 replications. The treatment consisted of four biomaterials namely sembung (Blumea balsamifera), gadung (Discorea hispida), tuba (Derris eliptica and betel nut (Areca catechu) with each concentration of 10.25.50 g/l. Each concentration used 4 snails as a test sample. The parameters observed were snail mortality, and Lethal Concentration (LC50 and LC95). The results showed that the gadung tuber extract had the highest toxicity as indicated by mortality of 75 % and the lowest LC95 value of 80.63 g/l. While the lowest toxicity is betel nut with mortality of 49.75 % and the highest LC95 value is 567.75 g/l. The Toxicity of tuba, pinang, and sembung are highest on 50 g/l concentration, excepted the gadung extract. In gadung extract, the highest toxicity was obtained on 10 g/l concentration. However, the application was consideration to the attack intensity of Achatina fulica (Ferussac, 1821) because the toxicity effect of biomaterial pesticide was slower than chemical molluscicide.Keywords: Achatina fulica (Ferussac, 1821), biomaterial, concentration, toxicity

Abstract

Bamboo is a multipurpose plant that has been used by the people for generations. This study aimed to describe the processing of bamboo and analyze its added value in Tasikmalaya Regency, West Java. Data was collected in April -December 2016 through interviews using questionnaires and field observations of bamboo craftsmen, and then were processed and analyzed quantitatively and descriptively. The community processed bamboo into woven products such as ayakan, boboko, haseupan, hihid, picnic basket, nyiru, pipiti, and parcel, as well as non-woven products such as piggy banks, key chains, glasses, wall clocks, lampshades, invitation boxes, bowl, cup, frame, teapot, letterbox, and tissue box. The average added value of woven products was IDR 131,197.21 or 9.11 % of the non-woven products, which was IDR 1,439,742.42. The average added value ratio of woven products is 0,83 and 0,90 for non-woven products. Bamboo woven business for household products is mostly done because the market has formed, stable, and has a wider scope even though it has lower added value. The market of non-woven products is smaller and specific even though it has a higher added value. A bamboo stem is only valued IDR 10,000 – 50,000, so it should be sold in processed products rather than the original form.Keywords: bamboo, processing, added value, woven, non-woven

Abstract

Belitong Island, The Province of Bangka Belitung is one of the exotic places with the biodiversity which has not been optimally inventoried. One of the potential germplasm that has not been recorded properly on Belitong Island is the mushrooms diversity and their potential uses. Mushroom are known as non-timber forestry product that is often sought after by local ethnic of Belitong Island and used as food. Apart from being consumed, these wild mushrooms are also traded, so they are one of the important seasonal commodities for the local community. This research aimed to provide the basic taxonomical information of wild edible mushroom in Belitong island as well as the biological characters. Observations were conducted 2 times in 2018 – 2019 using opportunistic sampling method. The utilization data of wild edible mushroom were collected to complete the macrofungi description in this study. A number of 5 edible wild mushrooms with th economic value reported in this study were: Amanita sect. caesarea (kulat pelandok), Heimioporus sp. (kulat pelawan), Hygrocybe cf. conica (kulat tiong), Phylloporus sp. (kulat sukatan) and Volvariella sp. (kulat sawit). Three species of fungi are ectomycorrhizal forming fungi, namely kulat pelandok with Schima wallichii, kulat pelawan with Tristaniopsis merguensis, and kulat sukatan which host is still unclear. Meanwhile the rest are saprophytic macrofungi. All wild edible mushrooms are members of the phylum Basidiomycota which are divided into 2 orders and 4 families. Heimioporus sp. is known to be the highest selling price mushroom compared to the others, which indicated the potential prospect to proceed to the cultivation stage. In addition, conservation management of plants that are hosts of ectomycorrhizal fungi need to be an important concern on Belitong Island.

Abstract

Screw tree (Helicteres isora Linn.) is a shrub species with 5 to 15 main stems where the natural distribution can be found in South Timor Tengah (TTS) regency of East Nusa Tenggara (NTT) province and it is potential as a medicinal plant. The fruits are the main material harnessed for traditional medicine or jamu. Recently, little is known on fruit productivity of screw tree under shaded and open area. At the field showed that there were differences on fruit and flower production under two shade condition and the main stems. The research aimed for gaining information on the effect of pruning on screw tree fruit productivity in the natural habitat under two shade conditions on fruit productivity. Split plot design was employed with two factors which were two shade conditions (shaded under trees and open) as a main plot and the pruning techniques as a sub plot. Pruning techniques had affected significantly on the number of shoots and fruits, and there was an interaction between treatments to the number of fruits. Shade conditions had an important role on fruit production. Plants grew under open space had better fruit characteristics on fruit length (46,94 cm), fruit diameter (6,41 mm), post-harvest fruit weight (0,94 g), oven-dried fruit weight (0,89 g) and lower water content (5,57 %), compared to under shaded space 44,16 mm; 5,73 mm; 0,87 g; 0,81 g and 6,95 %, respectively for fruit length, fruit diameter, post-harvest fruit weight, oven-dried fruit weight and fruit water content.

Abstract

The purpose of this study is to conflict mapping, explain conflict style of stakeholder  and choices of conflict resolution. This study was conducted in February 2017 in Cisantana Village, Kuningan Regency. Data were collected through participatory rural appraisal; interviews, field observation, documentation and focus group discussions.  The study method was used Rapid Land Tenure Assessment (RaTA) and Dispute Style Analysis (AGATA). The results showed that the dominant conflict in TNGC was the change of forest status which affected the economic activities of the community around TNGC, that involved eight dominant actor. In a conflict, the stakeholder has a different style of dispute. The stakeholders was facilitated and mediated to propose a permit to manage Patulungan (parking management), and a permit to manage Ipukan (tourism guide). In this case, the role of outsiders who do not have a conflict relationship is needed in order to realize conflict resolution.Keywords: conflict style,community, mapping, stakeholder, Ciremai Mountain

Abstract

Biomass estimation of secondary forests is required to support the emission reduction of carbon dioxide through an enhancement of forest carbon stocks. Commonly, forest biomass is indirectly estimated using tree biomass allometric models that are developed based on a destructive sampling of sample trees. The availability of biomass allometric models for secondary forests in Indonesia is still limited, particularly for secondary forest ecosystems in eastern Indonesia. This study aimed to develop allometric biomass models for mixed-species trees in a secondary forest of East Halmahera, North Maluku, and to compare their accuracies with some other allometric biomass models that commonly used for estimating biomass of secondary forests. The tree biomass measurement was conducted by using a destructive sampling of 18 mixed-species trees (with diameter range of 5,4 – 36,9 cm) in a secondary forest. The samples of each tree component (stem, branch, twig, and leaf) were analyzed in a laboratory to determine the biomass of each sample tree. Allometric models were developed by using a non-linear regression analysis, which were then compared with other allometric models. This study revealed that the biomass of mixed-species trees in the study area could be estimated accurately using the M7 model that used diameter, height, and wood density variables. Such local allometric model was more accurate than other allometric models commonly used for estimating tropical forest biomass. Alternatively, the M3 model that used diameter and height variables could also be used when wood density data was not available. The local allometric models from this study can enrich the availability of biomass allometric models for secondary forest ecosystems in eastern Indonesia.

Abstract

Langusei (Ficus minahassae (Teysm.et.Vr.) Miq) is one of the endemic flora of Sulawesi which existence is increasingly threatened. Attempts to maintain the existence of Ficus minahassae species by understanding the cultivation techniques of the langusei species, especially regarding the appropriate germination techniques, need to be addressed. This study aims to determine the level of fruit maturity and the appropriate extraction treatment for the germination of langusei seeds. The experimental design used in this study was a complete randomization design which is arranged in a factorial pattern. The first factor is the classification of the level of seed maturity based on fruit color categories: 1) Orange-brown fruit, 2) Orange-reddish fruit, 3) Red fruit, and 4) Red-black fruit, while the second factor is the fruit extraction treatment which consists of: 1) Extraction with dry wind treatment for 24 hours, 2) Extraction with drying treatment for 12 hours, and 3) Extraction with water treatment for 24 hours. The results showed that the fruit maturity level and the appropriate extraction treatment to produce optimal langusei seed germination were in the orange-brown and orange-reddish fruit (mature fruits prior to ripening) which was soaked in water for 24 hours.

Abstract

Cajuput leaf harvesting is a technical forest activity of non-timber forest products. The productivity of cajuput leaf harvesting is strongly influenced by aspects of human resource capacity and biophysical aspects. This study aims to identify the socio-demographic conditions of forest workers in cajuput leaves harvesting and to analyze the standards performance of harvesting in FMU Yogyakarta. A survey of 100 samples of workers were used to determine socio-demographic characteristics, while in-depth observations were made on 3 workers with different characteristics to determine work performance. The socio-demographic conditions of workers in the cajuput leaf harvesting are seen from eight characteristics, namely age, gender, education, number of dependents, livelihoods, and land ownership. Workers have an average age of 58 years old and are male. The level of education possessed by workers is dominated by graduating from elementary school (SD) by 64 %. The average number of dependents per worker household is 4 people, with the main livelihood being farmers. The average land ownership of workers in cajuput leaf harvesting is 0.17 ha. The work performance of harvesting for normal people in the FMU Yogyakarta is 72.23 kg / hour.

Abstract

Bunaken National Park was designation based on the Decree of the Minister of Forestry Number: SK. 734 / Menhut-II / 2014. Boundary demarcation process of Bunaken National Park in Mantehage Island was rejected by the community due to land claims in the form of gardens and settlements. This study puposes to answer how the state of land cover and use of the Mantehage Island and how the tenurial conflicts. The analysis used is spatial analysis and Rapid Land Tenure Assessment (RaTA). The results indicate that land cover and use consisted of primary mangrove forests, dry land agriculture, mixed gardens, scrub, settlements and roads. Conflict occurred between the community and the Forest Area Boundary Committee for North Minahasa Regency because the community did not understand the boundary demarcation activitiess and regulations that could provide a solution to their land conflict problems. Conflict resolution mechanisms that can be taken is the settlement of third-party rights in boundary demarcation process, review of spatial planning and conservation partnerships.Keywords: tenurial conflict, boundary demarcation, Bunaken National Park, conservation partnerships

Abstract

Calophyllum inophyllum L. is one of species that has been identified as a source of oil suitable for biofuel, cosmetics and medicine. Until now, the propagation of this species uses generative methods. In the forest tree breeding program, after a plus tree is selected a vegetative propagation technique must be developed to maintain the genetic potential of the parent tree. This study was conducted to determine the growth response of selected clones in Provenance Seed Stand of C. inophyllum in Wonogiri, Central Java propagated using the grafting method. The research used was arranged in Randomized Completely Design with 22 clones as the parent tree treatments. Each treatment consisted of 5 grafted seedlings and repeated in 4 times. The results showed that the survival percentage of grafted seedlings ranges from 15 – 100 % at 2 months of age, which showed a fairly high variation among the selected clones. Increasing the success of the grafting technique on the C. inophyllum clones still needs to be done so that it can provide vegetative material for clone testing and operational planting. It is important to be conducted in order to produce C. inophyllum stands with high fruit productivity and oil yield.Keywords: Calophyllum inophyllum, vegetative propagation, seedling growth, nursery
