Abstract

Bukit Ollon is located in Ollon, Bonggakaradeng District, Tana Toraja Regency. Toraja Tourism is known for its beautiful panorama, where the charm of the natural beauty of Bukit Ollon combined with the uniqueness of the local culture is a superior value for Ollon, so if estimated, it can provide high income for Tana Toraja tourism. Seeing these advantages, research was conducted related to the cultural vitality of the Ollon community and the community's strategy to respond to the potential environmental degradation that will occur in Ollon and Bukit Ollon due to the increasing number of tourists who will come. The method applied is in-depth interviews and visual observations in the field while implementing strict health protocols. The results found that the current cultural vitality in Ollon is high. The level of degradation found in the Ollon environment is low. The Ollon community can survive with its unique culture, even though there are still cultural relics of ancestors such as Liang Saratu, which are still maintained and are still very rarely visited. With the opening of tourism doors in Ollon to become superior tourism, the whole community is ready to anticipate degradation.

Abstract

One of the main tourist destinations in NTB Province currently is the Mandalika area, part of the Central Lombok region. This area is designated a Special Economic Zone (SEZ) based on PP Number 52 of 2014. Tourist visits increased drastically at the 2021 World Superbike (WSBK) event, and it is assumed that this will grow at the upcoming 2022 MotoGP event. An increase in the number of tourists has a positive and negative impact on the environment, along with increasing waste production. This research analyzed waste generation, composition, and effective waste management in the Mandalika SEZ. Analysis of waste production and composition will be carried out by referring to SNI 19-3964-1994 regarding methods for collecting and measuring samples of urban waste production and composition while analyzing waste management in the Mandalika SEZ, which was carried out by interview. The research results show that the average waste production in the Mandalika SEZ is 58.16 kg/Day. The most dominant waste composition is organic waste originating from food scraps, with an average of 39.56 kg/day, followed by the amount of plastic waste with an average of 16.41 kg/day. The smallest amount of waste at the research location is paper waste, with an average of 0.48 kg/day, and other waste is used diapers, with an average of 1.71 kg/day. The Waste Management Model shows that the average waste produced at the research location is 58.16 kg in one day. As a result of the indicators of waste production, in just one month, the waste production reached 1744.80 kg/day if it was not handled at all. Based on the research results, waste management modeling was produced by increasing public awareness, organic waste management using the Anaerobic Digestion Method and inorganic waste management using the recycling method. This modeling shows that the method applied can reduce waste production by up to 0.15%, namely 263.10 kg/day.

Abstract

One of the mangrove forests in Mempawah Regency is located in Siantan District. Mangrove forests have ecological, social, and economic functions to support the lives of living things that live around them. The extent and density of mangrove vegetation are essential parameters to determine the condition of mangroves in Siantan District to recommend rehabilitation that needs to be pursued. Data were collected from Landsat 7 images in 2010 and Landsat 8 images in 2021 with guided classification and visual interpretation to obtain a map of changes in mangrove land cover in 2010-2021. Vegetation density was obtained through Landsat Normalized Difference Vegetation Index (NDVI) analysis, divided into five density classes: very dense, dense, medium, sparse, and unvegetated. This study found that the secondary mangrove forests in Kecamatan Siantan decreased by 176.35 hectares during 2010-2021, turning into shrubs, open land, and plantations, especially in former pond areas. The most extensive deforestation turned 107.18 hectares of secondary mangrove forest into shrubs. Reforestation occurred during 2010-2021 amounted to 123.55 hectares. Natural or artificial bare land turned into 71.44 hectares of mangrove ecosystem. In 2010, the dense class dominated the mangrove forest density (60.03%) but decreased in 2021 (14.9%). A sparse class of density was not detected in 2010, but in 2021, the area of sparse density was 148.53 hectares, composed of shrubs and coconut plantations.

Abstract

Laminated wood's strength properties are influenced by the arrangement of each layers. This research aims to determine the effect of variations in layers of laminated wood to the shear bond strength, modulus of elasticity (MoE) and modulus of rupture (MoR) of laminated wood from Pine (P) and Sengon (S) wood using melamine urea formaldehyde adhesive (MUF). Laminated wood is tested using German standards DIN (Deutsches Intitut fur Normung), JAS 234-2007 and SNI 7973-2013. The data testing from 6 layer variation treatments were analyzed of variance in a completely randomized design (CRD) with 10 replications. The highest average value of shear bond strength for laminated wood in treatment G2 (Sengon-Sengon) was 6.17 N/mm2 which met the JAS 234-2007 standard (>5.4 N/mm2) while treatment G3 (Pine-Sengon) was 4.04 N/mm2 and G1 (Pine-Pine) of 2.78 N/mm2 cannot meet the standard. The highest average MoE was at A5 (P-S-S-P-P) at 8584.27 N/mm2 and the lowest at A3 (P-S-P) at 6210.99 N/mm2 included quality codes E8 and E6 in the SNI 7973-2013 Standard. The highest average MoR was at A4 (P-S-S-S-P) at 73.23 N/mm2 and the lowest at A5 (P-S-S-P-P) at 61.98 N/mm2, all treatments included quality code E25 (>25 N/mm2) and could meet JAS 234-2007 Standards (>36.0 N/mm2). The laminated wood in this study based on MoR is included to the strength class III – II and located between the strength class of Pine wood (strength class II) and Sengon wood (strength class III).

Abstract

Local communities widely use natural fibers to fulfill their daily needs. Doyo leaf fibers are fibers used by the people of Kalimantan for clothing and weaving traditional mats. This research analyses the fundamental properties of doyo leaf fibers, including chemical components, functional groups, and crystallinity index. The soluble extractive content of polar solvents was higher than the extractive content of non-polar solvents in doyo leaf fibers. The holocellulose content of doyo leaves is 60.47. The α-cellulose for doyo leaves was 53.51. The lower the α-cellulose yield, the more hemicellulose content dominates the fiber. The FTIR test results also support the chemical component test results. The high alpha cellulose content will affect the fiber’s crystallinity index. Doyo leaf fiber has a degree of crystallinity of 69.77%. Doyo leaf fiber is suggested as the raw material for crystalline nanocellulose.

Abstract

Energy needs continue to increase, resulting in energy reserves decreasing yearly, especially those made from fossil fuels, which are non-renewable energy, so their availability is limited. Therefore, efforts are needed to find alternative energy sources that can be developed. An energy source that can be produced is biomass. Gamal (Leucanea leucocephala)  and Lamtoro (Gliricidia sepium) plants are biomass often used as alternative raw materials for energy, namely biopellets, because they have high calorific value. This study aimed to determine the characteristics of biopellets from L. leucocephala and G. sepium with various compositions and particle sizes. The composition of the L. leucocephala and G. sepium raw materials is 1:1, 1:2, and 2:1 with a particle size that is passed 40 mesh retained 60 mesh, passed 60 mesh retained 80 mesh, and passed 80 mesh retained 100 mesh. Quality testing of biopellets based on SNI 8951:2020 includes density, moisture content, fly content, ash content, fixed carbon, and calorific value. The results showed that the biopellets were following SNI 8951:2020, namely the average value of density, moisture content, and ash content, for the parameters of the value of the flying substance content and fixed carbon were not in accordance. Statistics have shown that particle size significantly affects density, ash content, volatile matter, and fixed carbon. The composition affects the moisture content, fixed carbon, volatile matter content, and ash content. The best biopellets were produced in the treatment with 80 mesh particle size and 2:1 composition.

Abstract

Mangrove ecosystems are dynamic and vulnerable to external factors such as temperature, pH, and salinity. Changes in the quality of the environment and external conditions of the mangrove ecosystem can affect the arrangement of vegetation, species diversity, and the health and vulnerability of an ecosystem. The research aims to determine the environmental quality of external factors in the mangrove ecosystem by incorporating supporting data such as biota associations and pollutants. Measurement of environmental quality is carried out on plots of systematically dispersed samples representing ecosystems. The quality of the environment is measured using several parameters, such as temperature, salinity, pH, substrate thickness, and stagnation height, and the data is analyzed using observational and quantitative descriptive methods. The environmental quality conditions of the mangrove ecosystems in the Mondulambi Block, RPTN (National Park Management Resort) Kambatawundut, SPTN (Section of National Park Management) II Lewa, Manupeu Land Daru National Park cover salinity values ranging from 20-30 ‰ (ideal), soil pH ranges from 5-6.5 (tends to be more acidic), water pH ranges from 6-7.5 (optimal), the soil temperature ranged between 25-28°C, the water temperature ranging between 26-29°C (tendered to be lower), the lowest substrate thickness of about 2 cm and the highest thickness of 80 cm, the highest standoff height of about 9 cm, and the lowest standoff heights of around 2 cm. The results of this study describe the conditions of an ecosystem intended to be ideal.

Abstract

Indonesia is a country with geographical conditions located in tropical rain climates, causing variations in rainfall levels. High and varied rainfall can lead to surface run-off and soil erosion. This study aims to determine (1) the rate of surface run-off and soil mass erosion in acacia (Acacia mangium/A. mangium) stand, sengon (Falcataria moluccana/F. moluccana) stand, and open land; (2) the status of erosion hazard index, erosion hazard class, and erosion hazard levels occurring in A. mangium stand, sengon stand, and open land; (3) the relationship between rainfall and surface run-off and soil mass erosion. Erosion Measurement Plots (EMP) measuring 4 m × 10 m were established in the study site, consisting of three plots namely EMP A. mangium, EMP sengon, and EMP open land with steep slopes (25-45%). The total measured surface runoff (SR) during the study period at EMP A. mangium was 335.37 m³/ha/year, EMP sengon was 950.77 m³/ha/year, and EMP open land was 2,646.95 m³/ha/year. Meanwhile, Eroded Soil Mass (ESM) during the study period at EMP A. mangium was 0.85 tons/ha/year, EMP sengon was 2.39 tons/ha/year, and EMP open land was 195.45 tons/ha/year. The Erosion Hazard Index (EHI) value at EMP A. mangium and EMP sengon was classified as low, while at EMP open land was classified as very high. The Erosion Hazard Class (EHC) in EMP A. mangium and EMP sengon belongs to EHC I (very low), while in EMP open land belongs to EHC IV (high). Erosion Hazard Level (EHL) at EMP A. mangium and EMP sengon was included in the currently class, while at EMP open land was included in the very heavy class. The information about surface runoff and soil erosion on different land covers can be used as considerations in soil management, especially for post-mining lands.

Abstract

Information about colony fragments survival of the termite species Coptotermes curvignathus Holmgren in the laboratory is very limited. This study was conducted to determine colony fragments survival of the subterranean termite C. curvignathus Holmgren in laboratory maintenance. The test media used the Termitarium PSIH-IPB: 1999 as a glass vessel containing 4 kg of a mixture of sand and clay with 4 proportions and 4 different pH determined as treatments that would be studied for their effects on termite survival. The results showed that the proportion of the sand:clay mixture affected the survival and feeding preferences of the subterranean termite C. curvignathus Holmgren. The highest percentage of termites that survived was found in the termitarium containing a mixture of sand:clay 50:50. The highest percentage of bait wood weight loss occurred in the test media containing a mixture of sand: clay 50:50. The weight loss of bait wood is directly proportional to the termites survival.

Abstract

The color of wood is an important indicator that can be used for assessing the quality of wood, particularly for decorative product applications. This research aims to analyze the results of color changes in Solomon teak wood with impregnation modification (0.5 bar of vacuum for 60 minutes and 2.5 bar pressure for 120 minutes) using the impregnants monoethylene glycol (MEG) and polyethylene glycol (PEG). The Solomon teak wood used measures 2 cm x 5 cm x 10 cm, with a total of five repeated samples. The research results indicate that the treatment with PEG resulted in greater changes in brightness and color compared to aquades and MEG. The effect of impregnation with PEG and MEG on color change falls into the large category, while the category for wood impregnated with aquades is moderate.
