Abstract

Perum Perhutani has an important role in providing food and wood for people. Diversity and diversification of food will reduce the need for one type of food, namely rice as a staple food. Some tuber and rhizome are source of alternative foodstuffs, such as taro and arrowroot. This study aimed to determine the suitability and productivity of arrowroot and taro planted under old superior teak clones with several levels of stand density. Arrowroot and taro were planted under 14-year-old teak stands with 4 levels of density. Both plants were planted in the form of an array, measuring of 3m x 15m, with a spacing of 75cm x 75cm between plants. They were arranged in Randomized Completely with Block Design (RCBD) placed in 4 blocks of observation as replications.  The results showed that under superior teak clone had the potential to be planted with arrowroot and taro. Teak stand density influenced significantly some characteristics of arrowroot (leaves number, leaves area, stem height, stem diameter, root length) and taro (stem diameter, tuber diameter). Arrowroot productivity per hectare increased with low density of teak stands, accounted for 55, 59, 80, and 88 kg respectively. Meanwhile, taro productivity from very high to low teak density were 365, 301, 523, and 426 kg/ha. The novelty of this study is that there is no record of intercropping studies on old superior teak clones, so this is among the first studies. The benefit of from this research result, it could be employed by Perhutani to support the Indonesian government in the national food security program

Abstract

Gyrinops versteegii, belonging to the Themelaeaceae family, is one of the species producing high-grade agarwood. The induction technique can accelerate the agarwood product. This study inducted the G.versteegii tree with fungal species, a variation of hole position, and an induction technique. The research was done at a domesticated G. versteegii plantation in Sragen and Karanganyar District, Central Java Province. The agarwood quality resulted from the inoculated G.versteegii tree characterized by the wood aroma, the discolouration area, wood aroma, and terpenoid content, is significantly affected by the wood position in the stem, the fungal species, and the inoculation technique. The upper stem results the better agarwood than the bottom stem. Using the inoculant of the Fusarium oxysporum can achieve better agarwood than the inoculant of F.solani and mixed F.solani x F.oxysporum. Furthermore, the infusion technique gains a better agarwood result than others. Keywords: domesticated G.versteegii, wood aroma, discolouration, and terpenoids.

Abstract

Arrowroot (Maranta arundinacea L.) is a multipurpose plant that can grow under the stands so that the species has the potential to develop in the pattern of agroforestry. Initial information of arrowroot plant population as a source of germplasm for plant material/superior varieties and their agroecological characteristics in the field is indispensable. The study aims to determine the distribution, agroecological characteristics and potency of arrowroot in Garut regency. The methods include: (1) the study of literature and direct communication with stakeholders and the public, (2) field survey to collect data on distribution, cultivation status, abundance and productivity of arrowroot plant using a single plot, and (3) data collection of arrowroot agroecological characteristics include: vegetation analysis and geoklimat factors. The research results indicate that the arrowroot populations distribute in groups with a fairly broad ecological range i.e. altitude 6-1351 masl, temperature 20-36o C, relative humidity RH 40-72%, light intensity 12-56% dan pH 4.16-7,40 (acid to neutral) and in the low to high soil fertility condition. Falcataria moluccana as the major private forest species dominates in all zones of altitude, especially on the stage of the tree. Arrowroot abundance by elevation zones is 63,750 plants/ha (lowlands), 43,864 plants/ha (plains) and 73.333 plants/ha (plateau). The potential production for all elevations ranged from 15.40 to 163.2 g/plants. Cikajang and Cilawu populations have good potential to produce the high yield of tuber for arrowroot cultivation in Garut District.

Abstract

Agroforestry, the practice of growing trees and crops in interacting combinations, has a pivotal role to reduce the CO2 concentration in the atmosphere, and it subsequently sequesters the carbon in part of stems, branches, roots, and crowns of the trees composing their vegetation communities. The objective of the research is to know the carbon sequestration in the three agroforestry practices; those are multilayer tree garden, taungya, and home garden. The research was carried out from April 2017 to March 2018 at Sragen and Karanganyar regency central Java Province. Plot method, with the plot size of 20m x20m for trees, 10m x10 m for pole, and 5m x5m for sapling, was used in the sampling. The carbon sequestration was measured by Chave's allometric equation. The carbon sequestration of above ground the trees planted at taungya was 265.18 kg C ha-1 y-1, in home garden was 236.29 kg C ha-1 y-1, and in multi layer tree garden was 290.14 kg C ha-1 y-1. Seasonal fluctuation of the higest carbon sequestration in home garden occurs on October-December; in multilayer tree garden occurs on January-March; and in taungya occurs on July-September. Key words: Agroforestry practices, G.versteegii, seasonal fluctuation, Carbon sequestration

Abstract

Silvopastura merupakan bagian dari ragam implementasi agroforestry yang menggabungkan antara pohon dengan ternak atau hijauan pakan ternak. Kecamatan Kaligesing, Kabupaten Purworejo merupakan wilayah dengan program tahunan kontes kambing Peranakan Etawa (PE) dimana sumber pakan utama adalah Calliandra calothyrsus (kaliandra). Implementasi silvopastura dilakukan di lahan Perhutani dengan penanaman kaliandra dibawah tegakan Pinus merkusii (Pinus). Agroforestri sebagai praktek lama, ilmu baru menimbulkan konsekuensi adanya gap penelitian yang masih lebar. Terlebih lagi pada kasus agroforestri pinus dan kaliandra sebagai pakan ternak yang masih sangat terbatas. Penelitian ini bertujuan mendokumentasi implementasi pola silvopastura berbasis pinus dan eksplorasi aktivitas silvopastura yang diharapkan menjadi pondasi dalam rencana pengembangan silvopastura. Hasil penelitian yang diperoleh yakni (1) pola agroforestri yang terbentuk adalah alternate rows dan alley cropping; (2) aktivitas masyarakat berkaitan dengan silvopastura masih dominan terbatas pada penanaman dan pemanenan. Silvopastura di Kecamatan Kaligesing, Kabupaten Purworejo dapat dikategorikan sebagai praktek tradisional silvopastura. Penelitian ini dapat menjadi baseline dalam penyusunan rencana pengembangan dan penelitian lanjutan di masa mendatang.

Abstract

This study aims to determine the application of agroforestry patterns and their contribution to the income of farmers in the village of Samuda, North Halmahera Regency. The research method used was a purposive sampling method, with 30 respondent farmers who had coconut-based agroforestry land. Data collection and analysis are done descriptively and quantitatively. The results showed that two patterns of agroforestry application, the Agrisilvikultur Tress Along with Borders pattern and the Agrisilvikultur Random Mixture pattern, we're able to make many ecological and economic contributions. From the ecological point of view, mixed agroforestry patterns can increase resistance to plant diseases, and economically, agroforestry patterns can increase farmers' average income. Completion of coconut-based agroforestry in the form of copra increased the average annual income of IDR 35,633,333.3/year and the average income from secondary crops by IDR. 1,249,637,500/year. While the average income from non-agroforestry products is IDR 34,550,000/year. Comparison of income and expenditure shows that the average income of farmers is greater than the expenditure, so the application of agroforestry patterns has a significant influence on the level of welfare of farmers in the study area.
