Abstract

Decoupling resource use efficiency and ecological impacts are two challenges of oil palm smallholders in Indonesia. This study aims to find option for increasing productivity among smallholder and to reduce the environmental impacts of nutrient management in their plantations. We adopted UNEP’s definition of resource and impact decoupling as a tool to estimate resource decoupling rate and impact decoupling rate. The average smallholder’s resource decoupling rate from 2013 to 2017 is 0.86 kg fertilizer/kg fresh fruit bunch. This rate is 93.48% of the average of the companies (0.92 kg fertilizer/kg fresh fruit bunch) for the same period. Reducing the fertilizers dosages will reduce the resource decoupling rate and the impact decoupling rate by 58.14% (from 0.86 to 0.36 kg fertilizer/kg fresh fruit bunch) and by 67.32% (from 3.06 to 1.10 g CO2e/kg fresh fruit bunch) respectively. Reducing the fertilizer dosage is the most appropriate approach to increasing the resource and impact decoupling rates. We conclude that a smallholder is able to produce fresh fruit bunches sustainably by changing nutrient management practices and increasing access to certified planting material. Further study is required to include the influence of land use change on the impact decoupling rate as this factor was not included in our analysis.

Abstract

In recent decades, water resources shrink at an alarming rate in some areas both nationally and internationally. Water resources are directly proportional to the growth in human population. The higher demand for settlement and agriculture are considered to be important factors responsible for the degradation in water quality and resource functions. The aim of this study was to analyze the diversity of vegetation in the water resources area, as well as the level of human participation in the conservation efforts. The study was conducted using a mixed method based on observation and interviews of the local community. The plant diversity in the study area, Dandang water resource, consisted of medium category tree habitus (h'= 1.42); bush habitus (h'= 1.61); and herb habitus (h'= 2.29), there are 27 species from 15 families comprising 9 trees, 6 bushes, and 12 herbs. The level of human participation is still at the whim with limited operational support strength (0.80%). The social capital including communications between parties and organizing resources is a sufficient advantage (58%). However, the involvement of community and village governments in the conservation efforts is still weak (38%). The situation is aggravated by the lack of policies and regulations implemented by the village government (38%). Policy interventions and regulations are important, along with socialization and mentoring programs for the conservation of Dandang water resource area.

Abstract

Climate variability and change that affect extreme weather events has resulted long dry season and drought in Indonesia. Farmers become a vulnerable group since drought has damaged rice fields and as consequence losing their income. Therefore, rice farmers’ livelihood resilience needs to be enhanced in order to cope with those impacts. Crop insurance as financial capital could contribute to famers’ income stability from drought. Moreover, self-organization helps the farmers to understand agricultural risks and increase their adaptive capacity in times of extreme weather events. Accordingly, this paper investigate the impact of drought on rice production and farmers’ income, analyze the benefits of crop insurance and the support of self-organization to enhance livelihood resilience with a case of Kapetakan Sub-district in Cirebon Regency, Indonesia. The study employed mixed-methods by combining qualitative and quantitative data based on official data from government, in-depth interview, and literature review. The study reveals drought, for instance El Nino’s drought in 2015, has resulted in lower rice production and farmers’ income compared to 2014. Crop insurance could increase farmers’ income as compensation due to drought, nonetheless, there have been many farmers who do not have crop insurance yet. Moreover, self-organization related to the network capacity of farmers tends to be limited within farmer groups at village level. The government or other stakeholders should assist to expand the network of farmers in order to interact and learn with other organizations outside the region. Thus, knowledge and skills of farmers which inlude related to benefits of crop insurance and how to manage it will increase in order to choose adaptation option. This condition will contribute to enhance livelihood resilience of farmers to recover from extreme weather events.

Abstract

Produksi energi primer di Indonesia pada tahun 2018 yang terdiri dari minyak bumi, gas bumi, batu bara, dan energi terbarukan mencapai 1.504 juta SBM (Setara Barel Minyak). Ketergantungan penggunaan bahan bakar minyak (BBM) terutama di sektor transportasi masih tinggi. Komitmen global terhadap pengurangan emisi gas rumah kaca, mendorong pemerintah Indonesia untuk mendukung peran energi baru dan terbarukan. Penilaian siklus hidup (LCA) telah menjadi teknik populer yang diterapkan untuk mengevaluasi dampak lingkungan, konsumsi energi dan emisi GRK (Gas Rumah Kaca) dari produksi biofuel. Untuk mengevaluasi dampak siklus hidup biodiesel, banyak tahapan yang harus dipertimbangkan termasuk perubahan penggunaan lahan, perkebunan, milling, pemurnian, konversi bahan bakar. Sudah ada beberapa penelitian yang melaporkan siklus hidup produksi minyak sawit. Namun, sebagian besar masih berfokus pada emisi GRK dan kebutuhan energi. Oleh karena itu, dalam makalah ini akan menyajikan LCA dengan kategori dampak yang lebih luas dari produksi biodiesel di Indonesia mulai dari fase perkebunan hingga fase produksi. Berdasarkan analisis yang dilakukan, dapat disimpulkan bahwa penyumbang utama dampak lingkungan produksi biodisel adalah penggunaan pupuk pada tahap perkebunan dan proses transesterifikasi pada pabrik biodiesel.

Abstract

The reduced age function of Sengguruh Dam/Reservoir due to erosion in the upper of Brantas Watershed (Lesti Subwatershed area) interferes with its role in flood control, irrigation water supply and the supply of most of the hydroelectricity in East Java Province, Indonesia. This study aims to estimate erosion, analyze the interrelationship of the causative factors and provides environmental conservation direction. The research method uses mixed methods. The quantitative method of erosion rates is done by calculating the Modify Universal Soil Loss Equation which is supported by GIS tools. The qualitative method is carried out with questionnaires and interviews in the Lesti Subwatershed area. The results showed that the current erosion rate in each ha of land (average) in the Lesti Subwatershed was 153,868 tons / ha / year (exceeding the tolerable erosion rate of 30 tons / ha / year). The rate of erosion in the Lesti Subwatershed has always increased in the last 14 years. Of the 12 Subdistricts in the Lesti watershed, as many as 6 Subdistricts are identified as having high levels of Erosion Hazards so that they were a priority to be handled, namely in the Wajak, Dampit, Tirtoyudo, , Gedangan, Sumbermanjing Wetan and Bantur Subdistricts. Dampit Subdistrict, Turen Subdistrict and Gondanglegi Subdistrict also face behavioral problems and high population pressure compared to other Subdistricts. Research also shows that there is a relationship between erosion and knowledge, attitudes and behavior of the community in the form of population pressure and land use patterns. It is recommended that environmental conservation directives focus on these 6 Subdistricts through the application of soil and water conservation. The results of spatial analysis at priority locations suggest conservation measures in the form of law enforcement or counseling, and community empowerment to increase the ability and independence of the community through providing access to resources, education, and training.

Abstract

Private forest partnership has been considered as a new strategy in dealing with conventional socio-economic model problem of the industrial wood raw material sustainability supply. As a new strategy to address the issue of sustainability of industrial wood supply, synergy is needed between forest farmer groups and timber-based industry through private forest partnership schemes. This research aims to analyze private forest partnership policy and its implementation in terms of cooperation aspects in order to formulate a sustainable private forest partnership policy. Content analysis was used to identify all policies related to private forestry partnerships, while policy implementation was analyzed by using formal evaluation method. The descriptive method was implemented to analyze standing stock managemet, and Analytical Hierarchy Process (AHP) as a method to formulate the concept of sustainable private forest partnership policy. The results showed that private forest partnership policy now is more focused on production facilities and infrastructure aspect. The level of policy implementation in research location is at a low grade, only reached 16.28%, while 43.75% of the private forest partnerships in the research area are not sustainable due to low potential of standing stock. This research proved that fostering the farmers is a key factor to develop sustainable private forest partnership policy.

Abstract

ABSTRACTThe impact of activities in the watershed, either naturally or due to the role of humans, one of which is erosion. Erosion in watershed scale is related to natural resource management which involves social, economic, and environmental aspects. Lesti Sub Watershed as one of the upstream subwatersheds of the Brantas Watershed plays an important role in erosion contribution to the Sengguruh Reservoir in the downstream. Research related to erosion in the Lesti Sub Watershed so far has only been influenced by physical factors of the watershed such as slope, vegetation, and soil erodibility. The relationship between social aspects of community behavior towards land use choices and the magnitude of runoff erosivity is rarely done. This research attempts to examine this linkage with statistical, hydrological and spatial approaches in the framework of environmental science. The method used is a mixed method with behavioral analysis using cross tabulation, runoff discharge is calculated by the rational formula of modification and runoff erosivity is analyzed using the formula of Williams (1975) and GIS tools. Spatial analysis results show the more negative the community behavior in a district, the higher the runoff erosivity value and is on erosion prone land.Keywords: watershed management; behavior; land use; erosivity ABSTRAK Dampak aktivitas di dalam Daerah Aliran Sungai (DAS), baik alami maupun karena peran manusia salah satunya adalah erosi. Erosi berkaitan dengan pengelolaan sumberdaya alam yang melibatkan aspek sosial, ekonomi, dan lingkungan. Perubahan iklim global, meningkatnya jumlah penduduk, dan intensitas kegiatan ekonomi mempercepat perubahan kondisi DAS, termasuk di bagian hulu. Sub DAS Lesti sebagai salah satu Sub DAS di Hulu DAS Brantas berperanan penting dalam menyumbang sedimen sebagai dampak erosi yang tidak terkendali, sehingga berpengaruh terhadap umur guna Waduk Sengguruh di hilirnya. Penelitian terkait erosi di Sub DAS Lesti selama ini hanya dikaitkan dengan faktor-faktor biofisik DAS seperti kemiringan lereng, faktor vegetasi, dan erodibilitas tanah. Keterkaitan aspek sosial, yaitu perilaku masyarakat terhadap pilihan penggunaan lahan dan besarnya erosivitas limpasan adalah hal yang jarang dilakukan. Penelitian ini bertujuan untuk mengkaji keterkaitan ini dengan pendekatan statistik, hidrologi dan spasial dalam kerangka ilmu lingkungan. Metode yang digunakan adalah mixed method dengan analisis perilaku menggunakan cross tabulation, debit limpasan dihitung dengan persamaan rasional modifikasi dan erosivitas limpasan dianalisis menggunakan rumus Williams (1975) serta tools SIG. Hasil overlay peta erosivitas limpasan permukaan dengan peta perilaku dan tata guna lahan menunjukkan semakin negatif perilaku masyarakat pada suatu kecamatan, maka semakin tinggi nilai erosivitas limpasan dan berada pada lahan yang rentan erosi.Kata kunci: pengelolaan DAS; perilaku; tata guna lahan; erosivitas

Abstract

ABSTRACTThe sustainability of the ecosystem functions of the Upper Ciliwung Sub Watershed is disrupted, indicated by the exceeding of the minimum erosion hazard level compared to its tolerable erosion. This condition is caused by imbalance between forest areas compared to other land uses such as dryland agricultural, paddy fields, and settlement of the watershed. The purpose of this study was to determine the best watershed management practices in the Upper Ciliwung Sub Watershed based on the watershed sustainability model. The data for the sustainability model were obtained through the Analytical Hierarchy Process (AHP). The results showed that the area of forest had the highest value among other land cover aspects with a value of 52.8%. In succession, the next priority was the area of paddy fields by 24.4%; the area of dryland agriculture was 17.9% and the settlement area was 4.9%. It can be concluded that efforts were needed to: 1). Increase the area of forests and reduce the area of dryland agriculture; 2). Managing the area of settlements; 3). Increasing the area of paddy fields.Keywords: watersheds, management practices, environmental restoration ABSTRAKKeberlanjutan fungsi ekosistem Sub DAS Ciliwung Hulu terganggu, ditunjukkan oleh nilai tingkat bahaya erosi minimum yang melebihi batas yang dapat ditoleransi. Hal ini karena kawasan hutan memiliki proporsi yang tidak sebanding dengan luas pertanian lahan kering, luas sawah dan luas permukiman di wilayah tersebut. Tujuan dari penelitian ini adalah untuk menentukan praktik pengelolaan DAS terbaik di Sub DAS Ciliwung Hulu berdasarkan model keberlanjutan DAS. Data yang digunakan untuk keberlanjutan DAS Ciliwung Hulu diperoleh melalui Analytical Hierarchy Process (AHP). Hasil penelitian menunjukkan bahwa luas hutan memiliki nilai tertinggi di antara aspek tutupan lahan lainnya dengan nilai 52,8%. Secara berturut-turut, prioritas berikutnya adalah luas sawah sebesar 24,4%; luas pertanian lahan kering dengan nilai 17,9% dan luas permukiman sebesar 4,9%. Dapat disimpulkan bahwa diperlukan upaya untuk: 1). Meningkatkan luas hutan dan mengurangi luas pertanian lahan kering; 2). Mengelola luas permukiman; dan 3). Meningkatkan luas sawah.Kata kunci: Daerah Aliran Sungai, praktik manajemen, restorasi lingkungan
