Dual modification of sweet potato crosslinking-hydroxypropylation as biodegradable film materials
Authors: Saman W R , Yuliasih I , Sugiarto  
Published: December 2019

Abstract
Sweet potato starch as the base material for the biodegradable film has a hydrophilic nature that makes the mechanical properties produced less good. To overcome this weakness, modifications were made to starch with a double method of hydroxypropylation and crosslinking. This research was conducted in two stages, namely: modification and characterization of crosslinking–hydroxypropylation and then the making and characterization of biodegradable films. Biodegradable film modified sweet potato starch has a lower water vapor transmission rate (WVTR) than native sweet potato starch films. The tensile strength and percent elongation values of the entire modified starch films have higher values than natural sweet potato starch films. Transparency value has decreased, which indicates that the film is in good clarity. The solubility value is obtained lower because the high solubility value of the film indicates a decrease in the quality of the film to be used as a food packaging material because the film easily dissolves in water and increases the possibility of damage to packaged products, especially for products that are easily affected by moisture content.

Abstract
East Java BPBD data recorded 18 marine accidents in 2018, which increased by 1 event compared to the previous year. It is interesting to study the waters around East Java which are divided into 9 regions. The wind is a major factor in the high wave generation, but the contribution of weather phenomena triggered by the marine environment is important to identify. Phenomenon such as Madden-Julian Oscillation (MJO) has a cycle through the Indonesia territory, becomes a factor that should be suspected. MJO identification uses the Real-Time Multivariate MJO (RMM)-1 and RMM-2 index, which can be combined with the wind speed data using data mining classification techniques to get the thresholds value of wave height data obtained from the analysis of Windwave-05 model. The classification is helped by WEKA’s machine learning algorithm, by determining 4 selected classification algorithms including Naïve Bayes, J48, JRip, and Multi-Class Classifier. The data validation using the K-fold cross-validation method with a number of folds is 10 units. The accuracy value of the best algorithm obtained in each waters region ranges from 63.02% to 84.50%. The overall accuracy value increases by 0.24% to 4.41% compared to only using wind factors, except for the Waters of Bawean Island and Masalembu Islands.

Published: December 2019

Abstract
Rawa lebak lebung is a part of inland waters in South Sumatera which mostly used as the auction object, by granting a monopoly on fishing to Pengemin (auction winners). As an open-access resource, allowing a monopoly is considered to prevent conflicts of resource struggle and overuse. But in practice, the auction is precisely the cause of overexploitation, and the local community loses access to fishing. This study is intended to describe the suitability of Culture-Based Fisheries (CBF) implementation in the rawa lebak lebung in Ogan Komering Ilir (OKI) Regency based on practices under the auction regime, water quality, and aquatic biota communities. Increasing fish stocks and community involvement with CBF possible to develop with some adapted. This concept is carried out by spreading fish seeds to grow and harvest following fishing seasons, where local communities play an essential role. The analysis shows that the stock enhancement can be carried out in a limited way of the seed stocked. Poor swamp water quality requires the process of adaptation of seeds to be stocked. Community involvement is carried out by managing hatcheries, whose production is purchased by pengemin as an obligation to restore the environment.

Published: December 2019

Abstract
The waste of synthetic dyes from the textile industry causes environmental problems, and it is categorized as hazardous wastes. In contrast, the use of natural dyes is reported to produce fewer pollutants. However, the use of mordant for improving the quality of the dyeing process may release hazardous pollutants because mordant that is commonly used contains heavy metals. In order to claim that the use of natural dyes promotes the sustainable textile industry, it is challenging to find alternative sources of mordant-like materials that are environmental-friendly. It has been reported that tannins could replace mordant for dyeing process using natural dyes. This paper discussed the sustainability of the use of natural dyes in the textile industry based on economic, environmental and social aspects.

Published: December 2019

AbstractA study on Javan rhinoceros (Rhinoceros sondaicus) in Ujung Kulon National Park, Banten was done to monitor the levels of stress in their natural habitat. The study found that glucocorticoid hormone metabolite 3α,11β-dihydroxy-CM from feces was suitable for indicating the levels of stress in Javan rhino. The assessment was done to study stress variations among the three rhinoceros that had different levels of feed intake, as well as to study variations of stress levels in dry and rainy seasons. The result from this study showed that there were fluctuations of 3α,11β-dihydroxy-CM levels in two of the three rhinoceros. These fluctuations reflect the levels of stress associated with energy intake deficit (energy intake per body weight) and water deficit. This research shows that the deficit in energy intake per body weight, and water limitation are among the biggest sources of stress for rhino population. Stress originating from deficit of nutrients from food plan can be overcome by enriching the habitat of the Javan rhinoceros with high nutrient food plants such as stink vine (Paederiascandens), blackboard tree (Alstoniascholaris), and wild ginger (Costusspeciosus). Stress originating from water deficit can be mitigated by opening tracks and ensuring access to permanent year-round water sources.

Abstract
The population in Semarang City has been more and more increased while the demand for land for built-up area has also steadily increased. These conditions have increased the surface temperature which triggered the phenomenon of Urban Heat Island (UHI). This study aims to determine the impact of land use changes to the UHI phenomenon in the Semarang City. The data used in this study included remote-sensing satellite images of Landsat TM5 in 2008 and Landsat8 OLI in 2018. The methods used were Top of Atmosphere (ToA) correction, spatial analysis, and Land Surface Temperature (LST). The results showed that in the period of 2008-2018, there was an increased built-up area by 13% while the use of forest and plantations area was decreased by 7%. In the period of 2008-2018, the surface temperature rised from 18-33⁰C to 22-40⁰C. The land use that has a highest surface temperature was on built-up area, reaching as much as 26-30⁰C in 2008 and 30-34⁰C in 2018 while the lowest was on water bodies as much as 22-26⁰C in 2008 and 24-26⁰C in 2018. The changes of land use into built-up area have led to increase surface temperatures which have caused the UHI phenomenon in Semarang City.

Published: December 2019

Abstract
Sintang Regency is one of the 12 regencies and two cities in West Kalimantan Province, Indonesia. The total area of this regency is approximately 2.2 million hectares (ha) with 59% of the area designated as state forest area which provides high biodiversity and environmental services for adjoining communities. Through multi-stakeholder scenario planning, the government of Sintang Regency committed to protect and preserve forest resources for long-term landscape planning and sustainable utilization. Scenario planning yielded two possible outcomes in 2030 called “green” and “business as usual” (BAU) scenarios. Under the green scenario, future development without deforestation and land permits complied with spatial planning while under the BAU scenario, future conditions will be the result of past conditions without interventions. This study aimed to analyze land-use change in the regency over the past ten years. By applying the Terrset Land Change Modeller (LCM) algorithm, this study predicted the land use and carbon stock change of both scenarios in 2030. Three steps to apply the LCM are by analyzing the changes based on past history, modeling the transition potential and predicting the changes. Time series data of land cover data from 2006 to 2016 were used for this analysis. The results indicated that a green scenario prevents to stop deforestation about 117,136 ha (more than 5%) compared to the BAU scenario. Furthermore, the green scenario prevents the emission of 5 million tons of carbon (tC) for the regency indicating that the multi-stakeholder scenario planning process can be an effective strategy to preserve land and forest resources and promote sustainable development planning. The green scenario requires to prevent deforestation and limit the expansion of plantation areas, which are only allowed inside the current cultivation license and permit areas.

Abstract
The release of large-scale ammonia in the air by urea fertilizer plants Z has caused negative impacts on the environment, particularly to environmental pollution and human health. Some actions have been taken as a countermeasure, one of them is the development of Green Barrier, a living filter consist of various plantation that design based on its ability to absorb certain pollution substances in the ambient air. This article aims to analyze the development of the green barrier construction and its effectiveness as an effort to prevent the spread of ammonia gas around the urea fertilizer plant Z environment. Sequential explanatory with comparative analysis of data obtained from questionnaires using Spearman Coefficient Correlation, interviews, and data on green barrier construction processes used to achieve research objectives in this study. Based on the results of the study it was found that the existence of the green barrier was more effective in reducing noise than reducing the ammonia odour. This is also supported by field observations where the construction of a green barrier is still not fully optimal due to land acquisition problems, damage to several plants on the green barrier, and many green barrier areas that have not been planted by plants which are mainly bordered by community land.

Published: December 2019

Abstract
Solid waste has been recognized as a crucial environmental problem in many urban areas in Indonesia, particularly in Jakarta. In fact, an underperforming solid waste management (SWM) is also expected to result in an increased risk of water pollution. This research aimed at exploring past and current efforts of territorial water protection in Jakarta, Indonesia, which had been attempted by changing society’s behavior in managing solid waste at household level. To do so, this study applied literature reviews and interviews to investigate solid waste management of riverbank communities. According to a report on Environmental Statistics, there were 1.81% of households in the country’s capital in 2014 who managed their solid wastes by primarily throwing them into waterbodies. Apparently, un-transported solid wastes, which were those left lying on roadsides or empty lands, per day in the South Jakarta Region reached 8%. Those untreated wastes were expected to later end up in sewers, rivers, or the sea. In Srengseng Sawah, Jakarta, SWM has been conducted by non-governmental organizations, who received retributions from the people to transport household solid wastes. To overcome potential solid waste pollution in rivers, it is necessary to change community behavior to apply a more sustainable SWM in managing their household solid waste. This is strongly influenced by the availability of solid waste infrastructure and community awareness.
