Abstract

The exploitation of pine people forest in Tana Toraja has just begun since pine wood manufacturing industry opened in 2002. In 2004, the activity of this manufacture was stopped as some local people protested the activity. They assumed that the exploitation and manufacturing would cause negative effect, as the stand value could be much higher than benefits of the industry. In 2006, Tana Toraja Regency Government allowed the exploitation of the pine tree and offered the investors who were interested to invest their capital in the exploitation. The exploitation certainly needed a strategy based on accurate and comprehensive data.  The aim of this research was to arrange a strategy of pine people forest exploitation which could give both economy and ecology benefits. This research used financial analysis, SWOT analysis, and Analytical Hierarchy Process.  The result of the analyses indicated that the strategy could be best applied was strength-threat (ST) by increasing the role of farmer organization, conducting agroforestry pattern development in order to increase land productivity, applying proper regulating area for planting and harvesting, and assuring the exploitation of tongkonan area.

Abstract

Development of protected forest is often considered to be a way to preserve biodiversity and ecosystem service.  To keep protected area, Indonesia government excludinged local people from protected forest by making a policy which prohibits grazing on protected forest. However, the success of protected forest management often depends on the perception of local people because the policy has affected livestock owners who have an interest in forest use. Exclusion of local people from protected forest leads loss of people income and unemployment. This study applied a socioeconomic approach to examine and analyze the livestock owner perception on forest grazing prohibition in Timor Island of Indonesia by conducting a household survey of 36 livestock owners. The study results showed that 30.6%, 50.0%, 19.4%, 0%, and 0% of livestock owners are totally disagree, disagree, neutral, agree, and totally agree, with grazing prohibition, respectively. In addition, people perception was significantly affected by the number of livestock owned by people. It means that livestock owners mostly reject the policy on grazing prohibition. Indeed policy which prohibits grazing on the protected forest is not effective to be implemented. Government and policy maker should review the policy and consider the refusal of livestock owner toward exclusion policy. The interest of local people should be considered in developing a policy on protected forest.

Abstract

Melia azedarach is mostly found in community forests in West Java. One of the factors that affect forest productivity is high quality seed, but seed quality is not easily obtained by farmers. The general objective research is to provide good quality seeds of Mindi. Specific objectives are: 1) Determine the potential and the distribution of genetic resources of Mindi); 2) Determine the reproductive system; 3) ) improve  seed technology  to develop the seed viability of mindi, and 4) Build the collaborative management of mindi seed source by farmer. Seven  populations of mindi plantation in the community forests were chosen for this research. The study was conducted over three years (2009-2011). Biophysical condition such as  soil, light, temperature, altitude and humidity affect growth, flowering, fertilization and fruit production of mindi. The flowering cycle was proceeded for 6-7 months. The average value of reproductive success (KR) is 58%. The genetic variation of mindi in community forests in West Java was He = 0.1603-0.1956. The thickness of the seed coat, the high  content of lignin and ABA is create a difficulty in seed germination. Prospective populations to be developed for seed sources were proposed namely Sumedang, Wanayasa and Talegong.

Abstract

Sandalwood (S. album) is native species in eastern Indonesia, especially East Nusa Tenggara (NTT). Its species can produce essential oils and have been known to foreign countries. However, the community's interest in planting sandalwood is low due to a lack of knowledge regarding cultivation techniques and a long harvest period. The purpose of this study was to assess the growth of sandalwood (S. album) with cajuput (M. cajuputi) citronella grass (C. nardus) as the host plant. The research was conducted in Fatunisuan Village, Miomaffo Barat Subdistrict, TTU Regency using a completely randomized design (RAL) of 4 treatments and 3 replications, namely sandalwood without a host (K), sandalwood with cajuput host (CKP), sandalwood with citronella grass as the host plant (CSW), and sandalwood with cajuput and citronella grass as host plants (CKPSW). Data analysis used variance at 95% confidence level. Analysis of variance, which showed that the treatment had a significant effect, was further tested using the Duncan Multiple Range Test (DMRT) at the 5% level. The results showed that the mixed system using two types of hosts, namely lemon grass, cajuput or both, significantly increased the growth of sandalwood in the field. The CKPSW treatment gave the highest percentage increase in sandalwood growth compared to other treatments. Key words: cajuput host, citronella grass host, RAL, sandalwood

Abstract

Perkecambahan benih mindi (Melia azedarach) masih mengalami kendala, yang terekspresikan dari masih rendahnya daya berkecambah benih, sehingga akan mempengaruhi penyediaan bibit mindi yang berkualitas. Tujuan penelitian ini adalah mengetahui struktur morfologi, anatomi serta kandungan kimia pada benih mindi. Struktur morfologi dan anatomi benih didasarkan pada struktur makroskopis dan mikroskopis, sedangkan kandungan kimia benih adalah lignin, lemak dan Abscisic acid (ABA). Berdasarkan hasil pengujian terhadap struktur anatomi benih mindi, ketebalan endocarp berkisar antara 331,4 –1448,2 µm dan tebal testa berkisar 41,9–148,6 µm, dengan kerapatan sel berkisar 2031-4635 sel per mm2. Benih mindi mengandung ABA cukup tinggi (0,0386- 0,0955 mg/g ) dengan kadar lignin pada kulit benih termasuk kategori sedang yaitu berkisar antara 22,26-26,57%. Keberadaan ABA pada benih dapat menjadi faktor penghambat dalam perkecambahan, demikian pula dengan ketebalan dan kekerasan endocarp yang disebabkan oleh adanya lignin. Oleh karena itu perlu dilakukan delignifikasi untuk dapat meningkatkan daya berkecambah benih mindi.

Abstract

Slow-release fertilizer (SRF) with chitosan (CS) coating as a supply of plant nutrients is an alternative to the efficient use of conventional chemical fertilizers and reduces environmental pollution. However, its potential in woody plants is limited. This study aimed to analyze the effect of SRF on Falcataria moluccana germination and SRF phosphorus release rate. This study used SRF from polymerizing CS with methacrylic acid (MAA) to trap nutrients (CS-PMAA-nutrients SRF). The seeds of F. moluccana were germinated at six concentrations SRF: without fertilizer (F0), SRF CS dose 0.5% weight 0.03 g (F1), SRF CS 0.5% 0.01 g (F2), SRF CS 0.7% 0.03 g (F3), SRF CS 0.7% 0.01 g (F4), and conventional fertilizer (F5) for 21 days. SRF can increase the germination of F. moluccana. F4 increased normal sprout (10%) and germination power (16%) of F. moluccana. Furthermore, SRF with a concentration of 0.01 g produced a higher germination value than a concentration of 0.03 g. The release rate of SRF’s nutrients was slower (91.80% phosphorus) than conventional fertilizers. SRF application can reduce nutrients lost and increase the efficiency of nutrient absorption. Hence, it can improve F. moluccana growth.
