Abstract

 The use of chemical pesticides is often carried out in excessive doses, so that this condition results in increased accumulation of pesticide residues in nature. The residue can kill non target organisms, there was an explosion of secondary pests and pest resistance. One effort to reduce the use of synthetic chemical pesticides is by substitution using botanical pesticides that are more environmentally friendly. Botanical pesticides that are easily biodegradable in nature, so it does not pollute the environment, it is relatively safe for humans and the presence of natural enemies. One of the most potential types of botanical pesticides is from the Meliaceae family, namely neem, mahogany, and suren. In this study, the content of secondary metabolites was tested for neem, mahogany and suren seeds. Toxicity properties against pests conducted through literature searches. The purpose of this study was to obtain information on the toxicity and content of secondary metabolite compounds from the three plant seed extracts against forest pests. The results showed that the extract of neem, mahogany and suren seeds contain compounds secondary metabolites from the saponins, tanins, flavonoids, alkoloids, and terpenoids. The compounds can be used as botanical pesticides to control pests of forest plants.

Abstract

ABSTRACTCashew nut (Anacardium occidentale L.) shell is abundantly available as waste from chasew nut processing industries. Cashew nut shell is potentially used for activated charcoal. This paper characterize the porosity microstructure of activated charcoal made from cashew nut shells which is physically activated at various activation temperatures. Initially, cashew nut shells were collected and carbonized at 500°C for 3 hours. Then, the charcoal was activated at 800°C and 1000°C for 60 minutes. The characterization of microstructure porosity of cashew nut shell activated charcoal at transverse cross-section was carried out at 500 times magnification of 10 kV Scanning Electron Microscope (SEM) using a grain-shaped test sample. Observation of the porosity formed on the sample surface included pore size and frequency. Observation data were arranged in tabulated form and analyzed descriptively. The results showed that the frequency of pores in charcoal activated at 1000°C tended to be higher than that of charcoal activated at 800°C. The higher activation temperature increased the pore diameter of the charcoal and decreased the clogging residue.Keywords: mesoporous, pyrolysis, hydrocarbon

Abstract

The mangrove ecosystem in Pangarengan Village, Cirebon District, provides benefits for environmental services, including as carbon sinks and stores. In estimating the carbon storage of mangrove forests, in general, allometric equations are used. Unfortunately, the allometric equations currently available are still composed of the stages of growth of saplings, poles, and trees. Thus, the purpose of this study was to develop an allometric model for seedlings in mangrove forests. The research was conducted in June 2021 in the mangrove forest of Pangarengan Village, Cirebon District. The equipment that used in the study were calipers, measuring tape, digital scales, and crop shears. Research materials were mangrove seedlings of Rhizophora mucronata, Avicennia marina, and Sonneratia caseolaris. The best allometric model in estimating dried weight biomass with base diameter predictor is Y = 35,013 Dp1,860 (R2adj = 0,873; SEE = 0,472) using tip diameter predictor is Y = 249.573 Du2,276 (R2adj = 0,524; SEE = 0,710). While the allometrics for estimating the carbon content of seedlings were Y = 5,835 Dp1,804 (R2adj = 0,831; SEE = 0,528) and Y = 35,750 Du2,107 (R2adj = 0,607; SEE = 0,805). Thus, the power allometric model with base diameter predictor was quite good in estimating dried weight biomass and seedling carbon content in the mangrove forest of Pangarengan Village.

Abstract

Sengon (Falcataria moluccana (Miq.) Barneby & J.W. Grimes) is a Leguminoceae plant that is useful as material for making panel wood, furniture wood and trees that can rehabilitate critical land. Sengon seeds experience a period of dormancy and need to be managed. The purpose of this study is to determine the effect of temperature 600C and 50% H2SO4 concentration and soaking time on sengon seed germination. A complete randomized design (CRD) with two factors were used as research design. The first factor was the air temperature treatment of kontrol (A1), 60o C (A2), 50% H2SO4 (A3) and which consisted of 3 levels of treatment. The second factor was soaking time (T); T1: 35 minutes, T2: 8 hours. The results showed that the best combination of treatment and immersion time for all germination parameters of sengon seed is soaking seed at 60o C water for  8 hours Key words: Temperature water, H2SO4, Paraserianthes falcataria, germination

Abstract

ABSTRACTAir pollution is one of the main issues faced by urban areas. Therefore, morphological characteristic and colony coverage of lichen growing at different scale air-polluted area could become as a bioindicator of their air quality. This research aims to determine the condition of lichen in spots located at near and far from the main road (width ± 29 meter) in urban area at Banjarbaru town. This research used descriptive method with purposive sampling technique. Sample were obtained from 2 plots those were far and near the main road, each plot represented by samples from 5 different trees (densed canopy with minimum DBH at 25 cm). Lichens were taken at 50-150 cm above ground level using 20x20 cm quadrant plastic frame. Observation variables include the number and shape of colonies, color and type of thallus, and percentage of thallus cover. We determined 13 colonies from spots far from the main road (500-600 meter from main road). Lichen dominated by green to bluish color, thallus consist of crustose and foliose, and the average percentage of thallus cover was 28.01%. While from that near the main road (14-250 meter from main road), we determined 14 colonies predominantly consisted of white crustose lichens, and the average percentage of thallus cover was 10.01%. Traffic intensity showed to have significant effect on lichens community. The main difference can be seen from morphology and colony coverage. Based on this result, lichen can be used as bioindicator of air quality, especially air pollution caused by motorized vehicles.

Abstract

A special-purpose forest area (KHDTK) is the forest area which the purposes are for teaching and research activities. One of the research conducted in KHDTK Wanagama was examining the planting of superior Teak from breeding (jati Mega). The growth of clonal teak data can also be assessed for its carbon stock. Hence, the purpose of this research was to determine the potential of biomass and carbon stock in the Jati Mega stands at KHDTK Wanagama, Yogyakarta. The research was carried out using a non-destructive method which used the allometric equation Bt = 0.0149(D2.H)1.0855. Carbon value was calculated as 50% of the total biomass. The results showed that after 17 years of planting Jati Mega, the stand density was 665 trees/ha, carbon storage was 59.98 Mg C/ha, and carbon uptake was 220.11 Mg/ha (CO2-eq). The total value of biomass, carbon stock, and carbon dioxide removal by Jati Mega stands at KHDTK Wanagama was in the medium category. The advantage of this research is for understanding the environmental services of jati Mega as a forest carbon stock. Information on forest carbon stock can be used as basic data for forest management as climate change mitigation.Keywords: superior teak, climate change mitigation, carbon accounting, environmental services

Abstract

Kabesak (Acacia leucophloea) and angsana (Pterocarpus Indicus) are native plant species of Timor Island, which can be used for various purposes such as wood for construction and furniture. Efforts to cultivate these seeds need to be understood, especially by trying to use the technique of soaking seeds and watering using liquid organic fertilizer (POC) banana pseudo-stem. This study aims to determine the effect of POC banana pseudo-stem on the germination and growth of kabesak and angsana seedlings. This research is an experimentalresearch, with a completely randomized design method. There are 4 treatments of POC banana pseudo-stem concentration (25%, 50%, 75%, and 100%) and control (POC 0%). Observations of this study were carried out on germination, seedling height and number of leaves of kabesak and angsana seedlings. Data were analyzed using analysis of variance (Anova) and continued with Duncan Multiple Range Test (DMRT). The result showed that applying POC banana pseudo-stem affected germination and seedling height of kabesak, as well as germination, seedling height and the number of leaves of angsana. The growth parameter that was not affected by organic fertilizer watering was the number of leaves on the kabesak seedling. Treatment with 100% banana pseudo-stem fermented concentration was the most optimal in increasing germination, seedling height, and number of leaves of kabesak and angsana seedlings.Keywords: germination, liquid organic fertilizer, number of leaves, seedling height

Abstract

Forest degradation leads to forest fragmentation and changes in land cover on a landscape. These changes vary considerably between landscapes. This research aims to determine the effect of land cover on the diversities and potential carbon storage. Parameters measured on 6 types of land cover including: old plantations, young plantations, old shrubs, bamboo, plantation forests, and secondary forests. The size of the plot was 1 hectare consisted of 16 observation sub-plots for the measurement of saplings, poles, and trees. Diversity parameters were measured such as species and density, also ecological indices such as diversity, dominance, and evenness of the species. The allometric model was used in predicting the biomass of each land cover. The results showed that secondary forests had considerable diversity of species at the level of poles and trees, while old plantations were arranged by the most diverse poles. This condition was indicated by a diversity index of more than 2.5 for all regeneration levels.  Young and old plantation had a diversity index approaching secondary forest for poles so that forest management has been able to improve the species composition resembling their natural conditions.  Based on the potential for carbon/biomass storage, old plantations and secondary forests had a potential of 200 tons/ha or close to carbon storage of 100 tons/ha. The results of diversity analysis showed the potential of carbon storage were affected by land cover for trees and total (P value <0.00). Average carbon storage at old plantation and secondary forest were not different with results of Duncan’s test. Based on the parameter measurements, proper forest management will be able to increase and/or maintain the species diversity and carbon storage in certain landscapes.

Abstract

This study aims to mapping the business models of rattan woven craft venturess in Gohong Village, Kahayan Hilir District, Pulang Pisau Regency, Central Kalimantan. This research is a qualitative research with a case study technique. The analytical method used is the Business Model Canvas (BMC) approach with 9 (nine) block elements. The research results showed that the customers of the rattan business were segmented markets which were divided into three groups, including demographic, geographic and psychographic. The propositions of value that given were the quality, and variety of types and motifs of the products. Additionally, marketing channels were carried out both directly and indirectly by using several market players. The customer relationship developed in the form of personal assistance; meanwhile, revenue streams were derived from the product’s sales. Key resources consist of physical assets, group-owned capital, and trained human resources. The mainactivities in the rattan weaving craft business consisted of rattan cultivation, processing of raw rattan for ready-to-weave, weaving of the rattan, and selling of the products. The key partnerships included manufacturers of raw materials , sewing equipment shops, and synthetic leather shops. Finally, the cost structure included several costs for suppliying raw materials, transportation, communications and production equipment. The positive business model elements include broad market segments, quality products and trained human resources that must be maintained and developed. The negative business model elements such as limited capital and raw materials must be resolved.

Abstract

This study examines natural regeneration of tropical peat swamp forest after fire. The study area is located in Merang Peat Swamp Forest (PSF) in Musi Banyuasin District. Merang PSF is situated over a large peat dome that stores huge amount of carbon. 23 sample plots were established in the area burned in 2015. The regeneration of understorey, seedlings, and saplings was recorded in each plot. Meanwhile, peat depth and its maturity were identified to determine the soil characteristic of study area. After 3 years of fire, the area already covers densely by understorey mainly pakis udang (Stenochlaena palustris), pakis tanah (Nephrolepis exaltata), and resam (Gleichenia linearis) with depth of root zone reach about 40 cm in some plots. The native peat swamp species showed minimal regeneration during third years after fire due to understorey covering and limited number of surviving trees. The natural regeneration of woody species was dominated by bangun-bangun (Melicope glabra) and sepongol (Evodia sambuciana) which were calculated about 371 saplings/ha and 200 saplings/ha respectively. Those all two species also founded in the seedlings stage. The peat depth varied from 0.32 m to 4.71 m with peat maturity is dominantly hemic in the subsurface. This regeneration information provides useful indications for restoration options, which could be done by assisted natural regeneration
