Published: December 2019

The main function of applying biochar on acid mineral soil is to overcome soil acidity for optimizing the soil utilization. The high ability of biochar to retain nutrients can increase the efficiency of inorganic fertilizers. In the field, it can be reached by enriching biochar with inorganic fertilizers. The objective of study was to improve soil properties and inorganic fertilizer efficiency in degraded acid mineral soil in East Lampung. The study was conducted in 2018 at Taman Bogo Research station, Purbolinggo sub district, East Lampung district. The study used a randomized block design with 4 replications. Treatments tested were: 1) Cocoa shell Biochar (BC CS) + 100% Ponska dose (mixed), 2) BC CS + 50% Ponska dose (mixed), 3) BC CS + 100% ponska dose (digged), 4) BC corn cobs (CC) + 100% Ponska dose (mixed), 5) BC CC + 50% Ponska dose (mixed), 6) BC CC + 100% ponska dose (digged), 7) No BC+100% ponska dose (control). The parameters observed were the soil properties and crop yield. The results showed that BC CS was more effective in reducing soil acidity and yielded higher N, K and P significantly than BC CC. The biochar application can increase the K content up to 209-471%. Application a 50% Ponska dose only affected the soil K content. BC CC was better in improving soil physical properties than BC CC. The Ponska enrichment was more effective for BC CC application compared to BC CS although the highest yield was obtained in the BC CS application. The reduction of 50% Ponska dose decreased maize yield by 8.1% and 17%, but needed to be evaluated economically to choose profitable treatment.

Women in developing nations are more exposed to climatic risk due to higher dependence on the natural resources that tend to be more sensitive to these changes. Quality climate change information for rural women farmers can be a decisive factor in how they perceive and cope with these changes, thus the purpose of this study. Purposive sampling technique was used to select 5 communities each from the five Local Government Areas in Kwara North, giving a total of 25 communities. Raosoft online sample size calculator was used to determine the sample size. Three hundred and eighty-four (384) copies of the questionnaire were administered; in addition, Focus Group Discussion and oral interviews were conducted to determine the; (i) sources of climate information (ii) medium/language of communication and, (iii) adequacy of climate information. Results from the data analyzed indicates that about (68.0%) of all the women farmers in the study area do not always receive adequate climate information as their sources of information are not official, while only (32.0%) of the respondents received information in English. Also, the contents of climate information generated and disseminated in Nigeria and particularly the study area does not meet the actual needs of the farming population. Recommendations are therefore made accordingly for improvement.

Mangrove forests are part of coastal ecosystems that have a high level of vulnerability when faced with urban areas. The Kali Adem mangrove forest is one of the mangrove rehabilitation sites in the urban area. Rehabilitation efforts were initiated by Komunitas Mangrove Muara Angke (KOMMA) and PT. Pembangkit Jawa Bali-Unit Pembangkitan (PT PJB-UP) Muara Karang in 2010. The location was initially a garbage pile that was successfully cleared and planted with 37,000 mangrove seedlings. Administratively the site is located in Pluit, Penjaringan District, North Jakarta City, DKI Jakarta Province. Primary data were collected from field observation and interviews. In addition to that, secondary data, such as the high-resolution satellite World View’s image was utilized to analyze the dynamic of the landscape. Data analysis was carried out with qualitative descriptive methods to determine the influence factor of the successfulness of rehabilitation efforts. According to this study, the success of rehabilitation efforts in Kali Adem was influenced by several main factors including land stability, the certainty of land ownership, availability of mangrove seeds, and stakeholder involvement. Kali Adem biophysically formed from the sedimentation process and has the potential to disappear, the stability of the land must be maintained by the physical structure. The certainty of land ownership is one of the eligibility criteria for rehabilitation efforts. The availability of mangrove seeds is one of the factors that will determine the success of mangrove management. Mangrove management requires cooperation and participation by all levels of government and the involvement of the parties. Through the synergy of these factors, Kali Adem has successfully become an ecotourism area called Eco-marine Tourism.

Published: December 2019

The rate of population growth and the increase in food needs for consumption have made the need for paddy fields higher. On the other hand, the pressure on paddy fields is quite intense so that the conversion of paddy fields is quite challenging to be controlled. Moreover, the concerns about food security and food sovereignty have become critical issues. The high demand for land utilization has caused pressure on paddy fields in the Citarum watershed. The objective of this study is to build a model for maintaining paddy fields in the Citarum watershed. The study was conducted from June to September 2015. The method of this research is a modelling using system dynamics approach by simulating time series data. From the simulation, it can be concluded that the rate of conversion of paddy fields will still be high if there is no specific policy in its protection. This fact can be seen from various scenario conditions, either in existing circumstances, in the optimistic scenario, as well as in a moderate scenario. The strategy that can be done is that paddy fields should be specially protected or owned by the government to minimize the rate of conversion.

Authors: Pramulya R , Bantacut T , Noor E , Yani M
Published: December 2019

Agricultural waste has the potential of biomass as a raw material for producing renewable energy. The primary processing of coffee produces waste from pulping and hulling activities. Waste can be processed further through composting, anaerobic water waste treatment and burning to be converted into electrical energy. Therefore, the calculation is needed that estimates the amount of potential biomass that is converted. Then, the purpose of the paper is to analyze each stage in the life cycle of Gayo Arabica coffee and calculate the potential amount of electrical energy produced. The life cycle assessment method uses material and energy analysis intending to explain the flow of inputs and outputs within the system boundary and analyze the movement and transformation of materials, energy, waste, and emissions. In the context of the paper, the study uses material flow analysis to estimate the biomass potential from solid and water waste treatment. The study uses interviews, observations and a cooperative report located in Central Aceh district as an Arabica coffee producer area in Indonesia. Production of Arabica coffee is managed by cooperatives involving small farmers and collectors from cultivation, primary processing, packaging, and delivery. Cultivation uses the agroforestry system with a shade tree of the type of lamtoro (Leucaena leucocephala). Packing with a pack of burlap is done by the cooperative. Activities undertaken cooperatives include the acceptance of coffee beans from the collector. Since 2016 cooperatives implemented a policy of processing coffee beans at the collector level. The estimation of the study shows that waste treatment through anaerobic water waste treatment, composting and combustion from 1 ton of cherry coffee (primary processing) has an energy potential of 34 kwh.

Bengkalis has been widely known as one of the regencies in Riau Province that is dominated by peatland. Nevertheless, this regency is also known for its almost annually recurring peatland fires. Considering this issue, this study primarily aims to formulate peatland fire prevention strategy in Bengkalis Regency. This study was conducted through the Analytical Hierarchy Process (AHP) methodology. While having a high degree of consistency ratio among involved experts, the results of this study revealed that shrubs was the type of peatland cover that must be given priority attention. Meanwhile, the key criteria in implementing peatland fire prevention was budget availability. Besides, local governmental institution that should be prioritized to receive authority as the coordinator for peatland fires prevention was the Regional Disaster and Fire-Fighting Agency (BPBD-Damkar). In the meantime, sequentially, it seems that the best prevention alternative was to build and / or repair existing canal blocks; strengthened by the implementation of regional integrated security patrols; constructing and/or repairing of water reservoirs and boreholes; as well as the provision of zero-burning incentives to traditional cultivators. These findings are useful to support the local government in preparing a more proactive prevention approach in addressing peatland fires.

Published: December 2019

One of the major problems in watershed management is to balance the ecological function and fulfillment of human needs in a limited area. Rapid land-use changes often occurred as a result of human activities. Regular monitoring of land-use change dynamics is needed to help the government in making a decision within the area. Cisadane watershed is one of 15 priority watersheds in West Java Province, which categorized as very critical. This study aims to: 1) analyze land use/land cover (LULC) change dynamics and patterns in Cisadane watershed from year 2003, 2009, 2013, and 2018, 2) develop LULC projection for year 2033 based on historical patterns using Markov chain algorithm, and 3) analyze LULC change pattern and projection towards the spatial planning. The study reveals that the most significant changes during the last 15 years is the increase in built-up areas (47%). On the other hand, forest and paddy field classes are experiencing a decrease of 7% and 31%, respectively. LULC projection under business as usual (BAU) condition resulted in the continuous increase of built-up areas up to 36% in the year 2033, which most of the changes come from the conversion of paddy field and dryland farming. LULC map of year 2018 and regency’s spatial planning was overlaid to confront the consistency within both maps. The overlaid shows inconsistency between current LULC and land allocation in spatial planning. The inconsistency mostly occurred in the area allocated as plantation (86%). The built-up area has the largest allocated areas in Cisadane watershed, while it is only 51% of the areas that had been utilized as a built-up area. The result of this study indicates the need to strengthen land allocation policy within the watershed, in particular, to control the development of the built-up area.

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

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.

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

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.

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

A 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.

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.

Banten Province has a harvested area of paddy fields on the 2017 year of 415,687 ha and production of 2,369,731 tons of milled dry grain (MDG). The objectives of this study are: 1) Knowing the condition of wetland rice farming in Banten Province, 2) Knowing the factors that influence the production of wetland rice in Banten Province, 3) Knowing the efficiency of the use of production inputs. The sampling method used purposive sampling with 123 respondents. The analytical method used multiple linear of Cobb Douglas production functions and descriptive analysis. The results of the study are: 1) Rice paddy farming in Rainy Season (RS) 2017/2018 has a B/C ratio of 1.7. The productivity of paddy rice is 5.91 tons harvested dry grain (HDG)/ha. 2) Significant factors affecting the production of paddy rice in RS 2017/2018 are The amount of use of solid organic fertilizer, The amount of solid herbicide use, The amount of use of human labor rent, and the arable land area, 3). The cumulative elasticity is 0.97, is inelastic, meaning that the addition of 1% of the production factor will increase production by 0.97% or decreasing return to scale. So rice farming is relatively inefficient.

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.
