Abstract

ABSTRACT The upstream area of watersheds has a strategic role in controlling the water cycle, including controlling direct runoff to increase base flow and guide the fluctuation of river discharge. The objective of this study is to determine the base flow of Gajah Mungkur catchment area, which is located in the upper stream of the Bengawan Solo watershed, after 18 years of rehabilitation. To understand the base flow, river discharge measurements for 4 months were carried out at the River Discharge Observation Station (SPAS) which are equipped with automatic rainfall and water level recorders. Data analysis includes vegetation analysis, river discharge analysis, hydrograph analysis, and baseflow index (BFI) analysis. The total rain during the study was 45.8 mm and the average air temperture was 22.45˚ C. The pine forest density varied from low to high, with tree densities ranging from 569 - 919 trees/hectare. Results show that the BFI value in April-August 2017 is 44.63%. The increase of trees age in the Gajah Mungkur catchment area followed by changes in stand structure is considered to increase the ability of buffering capacity and regulating the area's water cycle.Keywords: base flow, pine forest, upstream, forest rehabilitation. ABSTRAKKawasan hulu Daerah Aliran Sungai (DAS) memiliki peran strategis dalam pengendalian daur air, diantaranya adalah perannya dalam mengendalikan aliran permukaan untuk meningkatkan aliran dasar (baseflow) dan menjaga fluktuasi aliran sungai. Penelitian ini bertujuan untuk mengetahui besarnya aliran dasar setelah 18 tahun direhabilitasi dengan studi kasus di DTA Gajah Mungkur yang terletak di hulu DAS Bengawan Solo. Pengukuran debit aliran selama 4 bulan dilakukan di Stasiun Pengamatan Aliran Sungai (SPAS) yang dilengkapi dengan alat perekam hujan dan debit aliran otomatis. Analisis data yang dilakukan meliputi analisis vegetasi, analisis debit aliran sungai, analisis hidrograf aliran dan analisis Baseflow Index. Total hujan selama penelitian yaitu 45,8 mm dengan suhu udara rata-rata 22,45˚C. Kondisi kerapatan tegakan bervariasi dari kerapatan rendah sampai dengan tinggi, dengan kerapatan pohon berkisar antara 569 -  919 pohon/ ha. Hasil analisis menunjukkan bahwa nilai BFI pada bulan April-Agustus 2017 yaitu 44,63%. Pertambahan umur tegakan di DTA Gajah Mungkur sampai pada umur 18 tahun diikuti dengan perubahan struktur tegakan sehingga diduga berdampak pada meningkatnya kemampuan penyangga dan pengaturan daur air kawasan. Kata kunci: aliran dasar; hutan pinus; hulu daerah aliran sungai; rehabilitasi hutan

Abstract

Kawasan hulu daerah aliran sungai telah lama dianggap memainkan peran strategis dalam konservasi air pada lanskap yang kompleks dan dinamis. Sementara banyak studi telah meneliti pentingnya upaya konservasi air, studi yang berfokus pada pengelompokan niat penduduk untuk terlibat dalam inisiatif konservasi air di hulu daerah aliran sungai masih belum banyak dipelajari. Untuk memahami bagaimana warga mengelompok, kami mengklasifikasikan warga di dua desa (Cibeusi dan Sanca) berdasarkan pendapat mereka yang khas terhadap variabel Theory of Planned Behavior (TPB), yaitu sikap, norma subjektif, kontrol perilaku yang dipersepsikan, niat perilaku, dan perilaku terhadap inisiatif konservasi air. Secara total, 200 kuesioner yang dapat digunakan dalam analisis telah diambil. Hasil penelitian menemukan bahwa warga dapat dikelompokkan menjadi dua kluster yaitu “pendukung konservasi air” dan “pendukung pasif”. Pendukung konservasi air dicirikan dengan kesepakatan yang tinggi pada semua variabel TPB, sedangkan pendukung pasif adalah sebaliknya. Temuan ini menegaskan bahwa persepsi masyarakat tidak homogen, tetapi merupakan kelompok individu yang memiliki pemikiran berbeda. Lebih lanjut, studi saat ini berimplikasi bahwa pengelola sumber daya air harus menyadari fakta bahwa masyarakat dapat dikelompokkan ke dalam kelompok yang berbeda berdasar pendapat dan kepentingannya masing-masing. Rancangan kebijakan, strategi, dan intervensi yang efektif harus dirancang sesuai dengan kelompok yang berbeda tersebut. ABSTRACTUpstream areas have long been considered to play strategic roles in the water conservation of complex and dynamic landscapes. While earlier studies have examined the importance of water conservation efforts, studies that focused on clustering residents’ intention to engage in water conservation initiatives in the upstream areas remain understudied. To understand how residents are clustered, we classify residents in two villages (Cibeusi and Sanca) based on their distinctive opinions of the Theory of Planned Behavior (TPB) variables, i.e., attitudes, subjective norms, perceived behavioral control, behavioral intention, and behavior toward water conservation initiatives. In total, 200 usable questionnaires were retrieved. The study finds that residents are clustered into two clusters named water conservation supporters and passive supporters. Water conservation supporters are characterized by high agreement on all the TPB variables, while passive supporters are the opposite. These findings confirm that communities are not homogenous but constitute a distinctive group of like-minded individuals. Furthermore, the current study implies that water resource managers should be aware of the fact that residents are clustered into distinct groups with their own opinions and interests. The design of effective policies, strategies, and interventions must be arranged according to those different groups.

Abstract

Forest rehabilitation is essential in restoring forest-based ecosystemservices (ES) provided by forest area. However, the critical issue on how locals perceived importance of forest rehabilitation, and how forest rehabilitation generates, both direct and indirect, benefits for the adjacent communities has remained contentious. A questionnaire survey was employed to examine locals' perceived importance, perceived ES, and attitudes toward forest rehabilitation in a village adjacent to Perhutani's forest area in the upstream of a catchment in Central Java, Indonesia. In total, 90 usable questionnaires were collected. The findings indicate that their perceived pine-sap production, conserving forest area, and water availability are the importance of forest rehabilitation programs. Locals recognized various ES benefits, including provisioning, regulating, supporting, and cultural services, though the adverse impacts emerged. Spearman rank correlation analysis revealed that local's satisfaction with forest rehabilitation positively and significantly correlated with their positive perceptions and subsequently increase their willingness to be actively involved in forest conservation efforts. The findings also imply that forest managers should not only focus on delivering benefits but also be aware of the adverse impacts of forest rehabilitation and management practices, which are crucial for ensuring forest sustainability. Jasa Ekosistem Berbasis Hutan yang Diterima dan Sikap terhadap Rehabilitasi Hutan: Studi Kasus di Hulu Daerah Aliran Sungai di Jawa Tengah, IndonesiaIntisariRehabilitasi hutan penting untuk memulihkan jasa ekosistem berbasis hutan yang disediakan oleh kawasan hutan. Sementara rehabilitasi hutan sangat penting dalam memulihkan jasa lingkungan, pertanyaan mengenai bagaimana penduduk setempat memandang pentingnya rehabilitasi hutan, dan bagaimana rehabilitasi hutan menghasilkan manfaat, baik langsung maupun tidak langsung, bagi masyarakat sekitar masih diperdebatkan. Kuesioner survey dilaksanakan untuk menggali persepsi masyarakat tentang tingkat kepentingan, persepsi terhadap jasa lingkungan, dan sikap mereka terhadap rehabilitasi hutan di desa berdekatan kawasan hutan Perhutani, di hulu daerah alisan sungai, Jawa Tengah, Indonesia. Secara total, 90 kuesioner yang lengkap berhasil dikumpulkan. Temuan menunjukkan bahwa persepsi masyarakat terhadap pentingnya rehabilitasi hutan yaitu untuk produksi getah pinus, melestarikan kawasan hutan, dan ketersediaan air. Masyarakat desa merasakan berbagai jasa lingkungan yang diperoleh dari kawasan hutan meliputi manfaat penyediaan, pengaturan, dukungan, budaya, meskipun dampak negatif juga teramati. Analisis korelasi Spearman menunjukkan bahwa kepuasan masyarakat terhadap rehabilitasi hutan berkorelasi positif dan signifikan terhadap persepsi positif mereka, dan selanjutnya akan meningkatkan kesediaan mereka untuk terlibat aktif dalam upaya konservasi kawasan hutan. Temuan ini juga menyiratkan bahwa pengelola hutan tidak hanya fokus memberikan manfaat, tetapi harus juga menyadari dampak buruk dari praktik rehabilitasi dan pengelolaan hutan yang muncul untuk memastikan kelestarian hutan.

Abstract

National parks (NPs) have become a rapidly growing segment of nature-based tourist destinations. However, the COVID-19 pandemic has impacted tourism activities across Indonesian NPs. While existing studies have scrutinized the impact of COVID-19 on tourism, studies that focused on clustering residents adjacent of NPs to support tourism amidst the COVID-19 pandemic remain underexplored. To unveil how residents are clustered, we assess residents in Ngadisari and Wonokitri villages based on their distinctive opinions of perceived benefits (PB), perceived costs (PC), perceived health risks (PHR), and support for tourism (ST). Totally, 354 respondents were obtained. We found that residents are clustered into two clusters named tourism supporters and cautious supporters. Tourism supporters are identified by their high agreement on PB and ST, and low agreement with PC. In contrast, Cautious supporters hold lower agreement in PB and ST, and higher agreement on PC and PHR. Our findings revealed that residents are heterogeneous and constitute a distinctive group of opinions and interests. Therefore, the design of policies and interventions should be adjusted based on those clusters. Key words: national park, perceived health risk, social exchange theory

Abstract

ABSTRACT COVID-19 pandemic has deteriorated nature-based tourism sectors around the world. Indeed, tourism site managers’ perceptions of and mitigation strategies to COVID-19 play a significant role in ensuring tourism operationalization and its management amidst pandemics. Using the case of Curug Cipeteuy, a community-based tourism destination in Gunung Ciremai National Park (GCNP), we investigate managers perceptions on COVID-19 and understand their mitigation strategies amidst the COVID-19 pandemic. A questionnaire survey, depth interviews, and field observation were conducted. We found that while managers' opinion of COVID-19 was relatively low, they hold high agreement in supporting tourism development amidst the COVID-19 pandemic. These could be related to those managers who are proud of tourism and its promising benefits to their area. Furthermore, both structural and non-structural mitigation strategies were done to overcoming pandemic impacts and inviting visitors. Key words: Curug Cipeteuy, mitigation, COVID-19, community-based tourism, national park

Abstract

The purposes of community service entitled "Kaliandra Planting as Energy Wood and Forage Livestock Feed on Agroforestry Crops Gerbosari Village Community Samigaluh Kulon Progo" are 1). To provide additional knowledge of Kaliandra (Calliandracallothyrsus) utilisation other than HMT that is as a raw material of energy source and 2). To practice the technique of Kaliandra planting on agroforestry system in Gerbosari Village. The way cattle developed in Dusun Keceme is "cut and carry system" or grazing system. Grazing systems make farmers provide land for HMT planting either in the form of grass or tree leaves. Public dissemination and discussion with the community resulted in an agreement that the program is not only Kaliandra planting, but the utilisation of Kaliandra as an energy wood and wood pellet introduction is needed by Keceme Hamlet community. Methods of implementation of community service are through 4 stages in one unity of scheme. The methods are 1) program dissemination, 2) counselling, 3) practice of using a wood pellet stove and 4) planting. The community service program can provide an initial understanding of the community of Keceme Hamlet about the benefits of Kaliandra as an alternative to renewable energy that is in the form of wood pellets. The technique of agroforestry cultivation of Kaliandra has long been practised by the people of Keceme Hamlet that is on the edge of the terrace of the land.

Abstract

Energy policy in the world has changed due to the climate crisis. As a result, the need for renewable energy supply is increasing. Trees in the forestry sector are a reliable source of biomass for renewable energy production. Community forests could play an important role in supplying biomass-based renewable energy production. The study aims to understand the attitude, subjective norms, and perceived behavioural control on Farmers Forest Group's intention in cultivating trees for energy in Yogyakarta Province. The Theory of Planned Behaviour approach was used to analyse the correlation between Attitudes, Subjective Norms, and Perceived Behavioural Control on Forest Farmers Group Intention in cultivating trees for renewable energy. A survey using an online questionnaire was conducted on Forest Farmers Groups in four districts in DI Yogyakarta; Sleman, Kulonprogo, Bantul, and Gunungkidul. The survey results were analysed using non-parametric statistics.The results showed a significant positive correlation between Attitudes, Subjective Norms, and Perceived Behavioural Control on the Forest Farmers Group's Intention to cultivate trees for renewable energy. The study provides policymakers and privates with insight into working with the farmers when they are about to implement biomass-based renewable energy programs
