Abstract

Tingginya kebutuhan masyarakat terhadap sumber daya hutan, jumlah penduduk yang terus bertambah dan tantangan krisis pangan akibat dampak perubahan iklim, memerlukan upaya peningkatan produktivitas lahan dan jumlah pasokan pangan, termasuk melalui praktik agroforestri. Hasil Survei Status Gizi Indonesia tahun 2022 mencatat angka stunting di Indonesia masih tinggi sebesar 21,6%, melebihi ambang batas WHO. Umbi garut ‘pangan agroforestri’ memiliki beragam manfaat kesehatan, merupakan pangan fungsional potensial mengatasi masalah gizi, stunting pada anak. Pencegahan stunting menjadi penting dengan mengonsumsi gizi seimbang berkualitas dari pangan beraneka ragam diantara melalui diversifikasi pangan dalam agroforestri. Untuk itu diperlukan upaya menyeluruh dan terintegrasi oleh pemangku kebijakan dan masyarakat dari hulu ke hilir, mulai dari peningkatan produktivitas di tingkat tapak, diversifikasi olahan pangan, dukungan pemerintah bagi usaha mikro, kecil, dan menengah (UMKM) dalam pengolahannya, hingga sosialisasi manfaat umbi garut yang saat ini masih belum banyak dikenal melalui berbagai program edukatif dan insentif.

Abstract

Yulianti, Siregar IZ, Wijayanto N, Tapa Darma IGK, Syamsuwida D (2011) Genetic variation of Melia azedarach in community forests of West Java assessed by RAPD. Biodiversitas 12: 64-69. Melia azedarach L. or mindi (local name) is one of the widely planted exotic species in Indonesia, mostly found in community forests in West Java. However, improving and increasing the productivity of mindi commmunity plantation in West Java requires information on patterns of existing genetic diversity. The present work was aimed at estimating the genetic variation of mindi by using RAPD markers. Outcome of the activities was to propose appropriate conservationand management strategies of genetic resources in order to support the establishment of seed sources. Six populations of mindi plantation in the community forests were chosen for this research, i.e Sukaraja (Bogor-1), Megamendung (Bogor-2), Bandung, Purwakarta, Sumedang and Kuningan. Five primers (OPA-07, OPY-13, OPY-16, OPA-09 and OPO-05) producing reproducible bands were analysed for 120 selected mother trees in total, in which 20 trees per locality were sampled. Data were analysed using Popgene ver 1.31, NTSYS 2.02 and GenAlEx 6.3. Based on the analysis, the observed number of alleles per locus ranging from 1.43 to 1.60, and percentage of polymorphic loci (PPL) ranging from 43.33 to 60.00.%. The levels of genetic variation were considered as moderate for all populations (He range from 0.1603 to 0.1956) and the the mean level of genetic diversity between population (Gst) was 0.3005. Cluster analysis and Principal Coordinates showed three main groups, the first group consists of 4 populations i.e Bandung, Kuningan,Purwakarta and Megamendung, the second was Sukaraja and the third was Sumedang. Based on Analysis of Molecular Variance (AMOVA), the Percentages of Molecular Variance within population (69%) is higher than that of between populations (31%). The moderate level of genetic variation in the community plantation forests, might be due to small population size, leading to reduce genetic variability. Further analysis is required to confirm this findings using other genetic marker.

Abstract

Wijayanto N (2011) Species identification and selection to develop agroforestry at Lake Toba Catchment Area (LTCA). Biodiversitas 12: 52-58. In order to improve land productivity surrounding the LTCA, the existing ITTO project tries to establish agroforestry system. The system will be designed to meet consideration of both sides. on one side is to generate the people awareness of the forest and land rehabilitation, and on the other side is to support the poverty reduction. The aims of this research are: species identification and selection to develop agroforestry at LTCA. Data collecting was carried out with: interview, group discussion, field observation, divining manual study, and PRA. The diversity of the available crop kind shows the number of choices to be developed by the farmer. The farmers generally have the economic objective to develop agroforestry, including increase in net income, risk reduction, increase in environmental service, and the wealth and savings accumulation. Various types of agricultural crops, plantations and forest trees were found in LTCA. They can be the basis for building a wide variety of agroforestry systems.Key words: catchment area, agroforestry system, sequential, integrated.

Abstract

Kegiatan pertambangan terbuka, khususnya batu kapur, berdampak terhadap degradasi hutan dan penurunan kualitas tanah. PT Solusi Bangun Indonesia Tbk menerapkan reklamasi untuk memulihkan lahan. Penelitian ini bertujuan menganalisis kualitas VESS tanah, menganalisis hubungan skor VESS dengan sifat fisik dan kimia tanah. Parameter yang diukur meliputi skor VESS, sifat fisik dan kimia tanah. Data dianalisis menggunakan uji ANOVA dan uji korelasi Pearson. Hasil penelitian menunjukkan nilai VESS berkisar antara Sq 2,84–4,51. Nilai VESS lahan monokultur termasuk kategori sedang, lahan agroforestri dalam kategori rendah, dan di lahan terbuka yang terendah. Jenis vegetasi, kerapatan tajuk, kadar air serasah, dan bobot serasah turut memengaruhi nilai VESS di lahan reklamasi. Penerapan sistem agroforestri dapat mempercepat perbaikan kualitas tanah. Nilai VESS memiliki korelasi yang tinggi dengan parameter sifat fisik dan kimia tanah. Hal tersebut menunjukkan metode VESS dapat mengevaluasi kualitas tanah di lahan reklamasi tambang kapur. Kata kunci: agroforestri, kualitas tanah, reklamasi, sifat tanah, VESS
