This study aimed to determine the quality of defective honey, bitter honey, and sweet honey produced by the Baduy community. The bitter honey was collected from locations where nectar was sourced from calliandra, mahogany, sengon, and kamboja trees. The sweet honey was collected from locations where nectar was sourced from fruit trees such as bananas, sugar palm, durian, jackfruit, and rambutan. The defective honey is sweet honey that produces gas and therefore it is bubbly and considered to be damaged by the Baduy community. The research applied the criteria of the Indonesian National Standard SNI 8664 (2018) to test the quality of honey. The results showed that defective honey fulfills five criteria, i.e.: HMF testing, ash content, insoluble solids in water, acidity, smell, and taste. Bitter honey fulfilled four criteria, i.e., testing of ash content, water-insoluble solids, acidity, and moisture content. Sweet honey fulfilled seven criteria, i.e., the testing of ash content, sucrose, water-insoluble solids, acidity, moisture content, odor, and taste. All types of honey did not meet the criteria of diastase enzyme activity and reducing sugar levels. This could be due to conditions and storage time of honey before testing.

This research aimed to assess the feasibility of herb agroforestry utilization in the community forest of Gerbosari Village, Kulon Progo. This research measured NPV (Net Present Value), Net B/C (Net Benefit-Cost Ratio), IRR (Internal Rate of Return), and AEV (Annual Equivalent Value) as the financial feasibility criteria. A stratified sampling method was employed in which sixty farmers were classified into three strata based on the size of their lands. Based on the financial feasibility analysis, in stratum I, the values of the criteria measured were NPV of IDR15,757,980.56/ha/25 years, Net B/C of 1.62, IRR of 22.12%, and AEV of IDR1,296,647.20/year. In stratum II, the values of criteria measured were NPV of IDR14,255,408.39/ha/25 years, Net B/C of 1.76, IRR of 23.78%, and AEV of IDR1,173,007.88/year. Finally, in stratum III, the criteria measured were NPV of IDR19,444,703.86/ha/25 years, Net B/C of 2.21, IRR of 32%, and AEV of IDR1,600,009.64/year. The results suggest that herb agroforestry plays an important role in farmers' livelihood particularly as a source of income in both the short and long terms. The herb agroforestry utilization contributes positively to the economy of Gerbosari Village, Kulon Progo District.

This research aimed to analyze the socio economic and its dynamics of the community in Sidomukti Village, Dendang District, and Pandan Sejahtera Village, Geragai District, Tanjung Jabung Timur Regency, Jambi Province. Respondents were selected purposively based on their farming practices on deep peatlands. Thematic and descriptive analyses were used in this research. The results showed that the majority of the communities of the two villages was Javanese who came to the villages through transmigration programs in the 1980s. Their had insufficient knowledge about peatland utilization because they used to manage mineral soil in their place of origins. Their main jobs were farmers, planters, and laborers with oil palm and areca nut as the main commodities. The average income in Pandan Sejahtera Village was IDR3,832,800/month, greater than in Sidomukti Village which was IDR3,661,850/month. Farmers tended to plant commodities that were currently favored in the market instead of their suitablility with the biophysical conditions of peatlands. Guidance is needed to improve farmers’ knowledge of land management and species selection that have high economic values and market captures as well as are suitable for biophysical properties of deep peatlands and agroforestry techniques.

The difference between agroforestry and monoculture planting system is the presence of organic materials input from the canopy tree or the roots. The study aimed to determine factors affecting micro-climate conditions, soil nutrients of C, N and to identify the influence of sengon plantation on snake fruits productivity. This research used the observation method and was conducted in Gadung village, Bangunkerto, Turi. The treatments were the location used pattern monoculture system (control), agroforestry with trees along borders (AFS), and full trees (AFT). The soil was sampled compositely one diagonal. Analyses descriptive and regressions were used to analyze data of the soil nutrient with the treatment and fruit productivity. The results showed that the presence of Sengon on salak plantation influenced micro-climates conditions due to canopy cover by sengon. A location AFT showed the highest value of C-org (1.7%), and N (0.1%) in all plots. Meanwhile, the productivity of fruits on the monoculture system showed the highest fruit production that was 1150 kg/ha. However, the results were not significantly different from AFS and AFT. The snake fruit productions of AFT and AFS were 1035 and 1085 kg/ha, respectively. The results suggested that sengon plantations increased soil fertility, i.e., C and N...

Law enforcement plays a vital role to prevent the extinction of endangered species, including the Sumatran tiger. We investigated the roles of private sector involvement in Tambling Wildlife Nature Conservation (TWNC) for supporting law enforcement by Bukit Barisan Selatan National Park (BBSNP) agencies. We explored the relationship between law enforcement in the environment and forestry on illegal activities within the habitat of the Sumatran tiger in the TWNC area. We collected data on law enforcement and illegal activities during the period of 2000-2018 from BBSNP and TWNC management through secondary data and conducted semi-structured interviews with selected persons, including managers and staff. Additional data on illegal activities data was also obtained through the SMART programme. Our study showed that law and non-law enforcement approaches on environment and forestry during 2001-2018 reduced illegal activities within the TWNC area. However, the approach was not effective to reduce illegal activities if not implemented synergistically. This was evidenced by the guard posts burning case in the TNWC area. We highlighted that the law and non-law enforcement approach on environment and forestry must be implemented involving more synergy ways to reduce illegal activities in the habitat of Sumatran tiger in TWNC.

Furniture products with significant added value are strategic commodities for the Indonesian economy. Therefore, this research aimed to determine the competitiveness of the Indonesian furniture industry in terms of marketing by making a comparison with Vietnam due to being one of Indonesia's main competitors in the furniture trade for decades. This research employed a literature study to collect data and an integrated comparative analysis using the 5P mixed market framework of position, product, place, promotion, and price. The results showed that both countries had similar market segments with sensitivity to illegal timber, for example, the US and EU. Vietnam was exceptional in offering lower prices since the Vietnamese furniture industry gained substantial support from the availability of abundant cheap labor and investment. Meanwhile, Indonesia was eminent in supplying raw materials from production forests, and its furniture industry had reached an augmented products level greater than Vietnam. Both countries have easy access to global shipping. Concerning promotion, Indonesia ought to emulate Vietnam by facilitating the furniture industry to participate in international exhibition activities to expand the furniture market network.

Community forest plays an equally important role in ecological aspects when compared to other types of forest, one of which is carbon storage that helps in mitigating global climate change. The existence of community forests that are part of urban areas is quite rare, so this research needs to be carried out considering its special location. This study aimed to estimate the carbon storage contained in urban community forests, Bandar Lampung City, Lampung Province. The methods used in this research were destructive and non-destructive. Carbon storage measurements were carried out in three carbon pools, namely aboveground biomass; necromasses; litter, and understorey. The measurements were carried out by a vegetation inventory on 15 plot clusters located in the study area. The results indicated that the average value of carbon storage was 54.59 tC/ha with a value interval of 48.93 tC/ha up to 60.26 tC/ha. Aboveground biomass held the largest percentage as a contributor to carbon storage 95.71%, followed by necromass 4.23%, litter and understory 0.05%.

Jangka Benah: Alternatif Solusi Persoalan Keterlanjuran Kebun Kelapa Sawit Monokultur di Kawasan Hutan Ari Susanti

Pada bulan Februari 2021 Pemerintah telah menerbitkan Peraturan Pemerintah (PP) nomor 23 tahun 2021 tentang penyelenggaraan kehutanan dan PP Nomor 24 tahun 2021 tentang tata cara pengenaan sanksi administratif dan tata cara penerimaan negara bukan pajak yang berasal dari denda administratif di bidang kehutanan. Kedua PP tersebut merupakan peraturan turunan untuk sektor kehutanan dari UU Nomor 11 tahun 2021 tentang cipta kerja. Pada kedua PP tersebut disebutkan bahwa upaya penyelesaian persoalan “keterlanjuran” kebun rakyat dan “tumpang tindih” izin usaha perkebunan sawit di kawasan hutan dilakukan dengan menerapkan jangka benah. Klausul ini muncul pada PP nomor 23/2021 pasal 82(2) dan pasal 213 serta PP nomor 24/2021 pasal 27(4a) dan pasal 28 (3a). Jangka benah merupakan periode waktu yang dibutuhkan untuk mencapai struktur hutan dan fungsi ekosistem yang diinginkan sesuai tujuan pengelolaan (Davis et al. 2005). Apabila dikaitkan dengan kondisi “keterlanjuran” kebun sawit monokultur di dalam kawasan hutan yang berdampak pada terganggunya struktur hutan dan fungsi ekosistem yang ada, maka jangka benah dapat diartikan sebagai periode waktu yang dibutuhkan untuk memulihkan kondisi yang terganggu tersebut. Pemulihan tersebut dapat dilakukan melalui dua tahap yakni pada tahap pertama menuju kondisi kebun campur atau agroforestri kelapa sawit dan tahap kedua kondisi yang menyerupai hutan alam. Hasil analisis data spasial menunjukkan bahwa terdapat sekitar 3,4 juta ha kebun kelapa sawit monokultur di dalam kawasan hutan dimana sekitar 22% dikelola oleh masyarakat dan 78% dikelola oleh korporasi (Auriga 2019). Keterlanjuran tersebut terjadi pada hutan produksi yang dapat dikonversi (HPK), hutan produksi (HP), hutan produksi terbatas (HPT), hutan lindung (HL) dan kawasan suaka alam atau KSA/PA dimana lebih dari 40% berada pada HP. Luasan sebesar 3,4 juta ha ini mencakup sekitar 21% dari luas total kebun kelapa sawit berdasarkan data Kepmentan Nomor 833 tahun 2019 tentang penetapan luas tutupan kelapa sawit Indonesia tahun 2019. Besarnya luasan dan beragamnya tipologi keterlanjuran kebun rakyat dan tumpang tindih izin usaha di kawasan hutan ini maka implementasi perlu dukungan yang komprehensif dari aspek kebijakan, kelembagaan dan sosio-teknis di tingkat tapak. Pada aspek kebijakan, PP nomor 23/2021 dan PP nomor 24/2021 merupakan payung hukum bagi implementasi jangka benah untuk menyelesaikan persoalan keterlanjuran kebun rakyat dan tumpang tindih izin usaha di kawasan hutan. Saat ini KLHK sedang menyusun rancangan Permen LHK tentang pengelolaan perhutanan sosial dimana pada rancangan Permen LHK tersebut pada BAB VII berisi tentang jangka benah kebun rakyat. Namun demikian, belum ada peraturan untuk implementasi jangka benah pada pelaku usaha yang mengalami tumpang tindih perizinan usaha di kawasan hutan seperti diamanatkan oleh PP nomor 24/2021 pasal 27(4a). Hal ini patut disayangkan karena sebagian besar dari keterlanjuran kebun sawit di kawasan hutan dikelola oleh korporasi, sehingga perlu disusun peraturan untuk pelaksanaan implementasi jangka benah pada pelaku usaha yang mengalami tumpang tindih perizinan usaha di kawasan hutan. Implementasi jangka benah yang efektif perlu dukungan kelembagaan yang solid di semua level. Pada rancangan Permen LHK tentang pengelolaan perhutanan sosial, pasal 213 telah mengatur tentang dukungan pemerintah pusat dan pemerintah daerah dalam implementasi jangka benah dalam skema Perhutanan Sosial dalam bentuk: (a) bimbingan teknis jangka benah; (b) peningkatan kapasitas sumberdaya manusia; (c) bantuan penyediaan bibit tanaman kehutanan dan (d) monitoring dan evaluasi. Berdasarkan hal tersebut maka akan diperlukan sumberdaya manusia dan anggaran yang cukup banyak untuk mendukung internalisasi jangka benah dalam perencanaan pengelolaan di tingkat tapak, bimbingan teknis dalam implementasi jangka benah di tingkat tapak serta monitoring dan evaluasi dari implementasi jangka benah tersebut. Kurikulum pelatihan bagi para pengelola kawasan di tingkat tapak dan pendamping lapangan perlu diperkaya dengan materi-materi terkait dengan perencanaan, implementasi dan monitoring serta evaluasi jangka benah. Di samping itu, adopsi jangka benah oleh petani dan para pelaku usaha yang mengalami keterlanjuran menjadi faktor yang menentukan keberhasilan implementasi jangka benah. Proses pengambilan keputusan petani dan pelaku usaha untuk mengadopsi suatu teknologi baru dalam hal ini adalah jangka benah akan dipengaruhi oleh faktor internal dan eksternal. Faktor internal meliputi (a) persepsi dan (b) motivasi, sedangkan faktor eksternal meliputi (a) karakteristik rumah tangga, (b) karakteristik biofisik dan (c) dukungan eksternal (Powlen & Jones 2019). Hasil penelitian terhadap persepsi petani tentang agroforestri sawit sebagai salah satu strategi implementasi jangka benah untuk menyelesaikan keterlanjuran kebun rakyat di kawasan hutan menunjukkan bahwa diperlukan contoh-contoh empiris di lapangan bagaimana jangka benah pada berbagai tipologi dapat diadopsi oleh petani dan pelaku usaha dalam rangka penyelesaian keterlanjuran kebun rakyat dan tumpang tindih izin usaha di kawasan hutan (Susanti et al. 2019). Saat ini sudah dibangun demonstration plot (demplot) implementasi jangka benah oleh Fakultas Kehutanan UGM bekerjasama dengan Yayasan Keanekaragaman Hayati (KEHATI) dan para mitra seluas 67 ha di provinsi Jambi dan 93,1 ha di provinsi Kalimantan Tengah. Namun demikian, demplot tersebut hanya mewakili sebagian kecil dari tipologi yang ada. Untuk itu, perlu perluasan demplot jangka benah yang mewakili berbagai tipologi keterlanjuran. Di samping itu, perlu akselerasi produksi dan disseminasi pengetahuan tentang jangka benah terutama terkait dengan aspek sosio-teknis bagi petani dan pelaku usaha yang mengalami keterlanjuran tersebut. Ketersediaan contoh dan informasi tentang jangka benah yang cukup diharapkan akan dapat meningkatkan adopsi jangka benah sebagai salah satu alternatif solusi persoalan keterlanjuran kebun kelapa sawit monokultur di kawasan hutan.

Apis cerana became a common species for beekeeping activities in Indonesia. The sustainability of beekeeping activities depended on the availability of feeds in forests with various plant species, which served as honey bee forage. Therefore, this study aimed to determine the forage plant diversity for A. cerana beekeeping in Wanagama Education Forest, Gunungkidul, from November 2018 to April 2019. Data collection was done through the inventory of trees and understorey plant species around the apiary locations to measure their abundance, flowering conditions, and the number of honey bees on the flower. The analysis indicated that 20 species (10 families) of trees and 60 species (19 families) of understorey plants had potential forage. The observation revealed that honey bees collected nectar and pollen from seven species of trees and 12 species of understorey plants. The highest visitation intensity was in the morning from two trees (Acacia mangium and Eucalyptus grandis) and three understoreys (Oxalis barrelieri, Passiflora suberosa, and Zea mays). Information on potential plant species for honey bee forage could improve beekeeping development in Wanagama Education Forest.

Kapok wood (Ceiba pentandra (L.) Gaertn) is a low-density wood species that can become a light construction material in the form of laminated timber products. This study aimed to understand the properties of laminated timber from kapok wood at different sawing patterns of laminae and core layer orientation. This study used kapok wood produced from community forests and PVAc (Polyvinyl Acetate) resin as the binder to produce laminated timber. The laminated boards were manufactured from dried laminas, measuring 100 x 9.5 x 1.7 cm, and were glued together with the resin before being pressed and clamped with the pressure of 1 MPa for 12 hours. The dimension of the final laminated board was 100 x 38 x 5 cm. Before being cut for the physical and mechanical properties tests, the laminated boards were conditioned at room temperature for a week. The results indicated that sawing patterns had insignificant effects on moisture content, density, static bending properties, and bonding strength of laminated boards. The core layer orientation had a significant effect on the density and the modulus of rupture. Generally, laminated board from kapok wood with the parallel grain direction of the core layer resulted in higher static bending properties and...
