Abstract

Gandaria (Bouea macrophylla Griff) is the identity flora of West Java Province. Naturally, the gandaria habitat in West Java is found only in the Yan Lapa Nature Reserve (CAYL) and Dungus Iwul Nature Reserve (CADI). In the ecosystem of CADI, and CAYL the position of gandaria in the community shows a low level of dominance. The presence of invasive species in CAYL and CADI is feared will threaten the stability of ecosystems in the region in the future including the presence of native flora. This study aims to study the level of tolerance and adaptation of gandaria in nature by knowing the pattern of individual spread in the gandaria population and the type of gandaria association with other species in various environmental. This is interesting to study because of the limited efforts of species conservation and genetic conservation of gandaria, while the condition of the natural population is increasingly threatened. Individual distribution patterns in gandaria populations in CADI and CAYL are random and clustered. Gandaria at Dungus Iwul Nature Reserve and Yan Lapa Nature Reserve are positively associated with iwul, whereas the Hawuan is negatively associated. Gandaria is not associated with asam keranji, manii, kokopian, leungsir, putat, and teureup. However, gandaria is not with menteng monyet dan kitulang in CADI while in CAYL have positive position.Gandaria (Bouea macrophylla Griff) merupakan flora identitas Provinsi Jawa Barat. Secara alami, habitat gandaria di Jawa Barat hanya terdapat di Cagar Alam Yan Lapa (CAYL) dan Cagar Alam Dungus Iwul (CADI). Dalam ekosistem CADI, dan CAYL posisi gandaria dalam komunitas menunjukkan tingkat dominasi yang rendah. Kehadiran spesies invasif di CAYL dan CADI dikhawatirkan akan mengancam stabilitas ekosistem di kawasan tersebut di masa mendatang termasuk keberadaan flora asli. Penelitian ini bertujuan untuk mempelajari tingkat toleransi dan adaptasi gandaria di alam dengan mengetahui pola penyebaran individu pada populasi gandaria dan jenis asosiasi gandaria dengan spesies lain di berbagai lingkungan. Hal ini menarik untuk dikaji karena terbatasnya upaya konservasi spesies dan konservasi genetik gandaria, sedangkan kondisi populasi alaminya semakin terancam. Pola sebaran individu pada populasi gandaria di CADI dan CAYL bersifat acak dan mengelompok. Gandaria di Cagar Alam Dungus Iwul dan Cagar Alam Yan Lapa berasosiasi positif dengan iwul, sedangkan Hawuan berasosiasi negatif. Gandaria tidak diasosiasikan dengan asam keranji, manii, kokopian, leungsir, putat, dan teureup. Namun gandaria tidak dengan menteng monyet dan kitulang di CADI sedangkan di CAYL memiliki posisi positif.

Abstract

Good quality cajuput seedlings procured from generative propagation are essential, since the mature trees will be functioning as oil production trees, stock (parent) plant for stem cuttings, and major players on land conservations.In addition to superior genetic factors, the so-called Plant Growth Promoting Rhizobacteria (PGPR) treatment with the optimum concentration would help in enhancing the quality of generative seedlings. Therefore, systematic experiment is needed to determine the effective concentration of PGPR required for preparing high quality cajuput seedlings. This study used Completely Randomized Design (CRD) experiment with randomly assigned concentration of PGPR on cajuput juvenile as the primary factor. The height growth and root length growth of the juvinile for given period of time were measured to evaluate the effect of PGPR treatment. There were monotonically improvement on juvinile’s height and root length growth after PGPR treatment, showing a positive correlation between the height and root length. During the experiment, the highest PGPR concentration of 90mL/L was discovered to be the most effective. Nevertheless, they still had not reached the saturation point yet, therefore, more study is needed to determine the most optimum PGPR concentration to produce the exemplary cajuput seedlings.

Abstract

The condition of social, economic, and culture of forest community has effect to forest condition. Desa Sindulang is one of village that community forest in Taman Buru Masigit Karembi that has majority of farmer and low economic condition. But commodity planting is carried out without an evaluation of the land to determine the level of suitability of the land with the commodities planted. The method by overlay Land Mapping Unit with society land use then analyze of matching suitability land. The results of evaluation divided in 3 units, are : 1) unit I which have land suitability class values with forestry commodities such as Suren (Toona sureni) and Coffee (Coffea Arabica) while agricultural commodities such as Broccoli (Brassica oleracea), Chili (Capsicum annum), Banana (Musa acuminate) and Cabbage (Brasica oleracea). 2) Units II which have land suitability class values with forestry commodities such as Suren (Toona sureni) and Coffee (Coffea arabica) while agricultural commodities such as Tomato (Solanum lycopersicum). 3) Units III which have land suitability class values with forestry commodities such as Suren (Toona sureni), Africa (Maesopsis eminii) and Coffee (Coffea arabica) while agricultural commodities such as Tomato (Solanum lycopersicum), Eggplant (Solanum melongena) Broccoli (Brassica oleracea), Chili (Capsicum annum), Cabbage (Brasica oleracea) and Pineapple (Ananas Comosus).Keywords : Agroforestry, Land suitability, Sindulang Village

Abstract

Masigit Kareumbi Game Park (Taman Buru Masigit Kareumbi or TBMK) is a conservation forest that can be used to accomodate game tourism with 12.42070 ha area. In 1998, PT. Prima Multi Sarana (PMS) was given permission to conduct pine resin extraction in 2005 in TBMK area of PT. PMS; however they disobeyed the code of conduct by taking away the wood forest products (Hasil Hutan Kayu or HHK) causing forest damage that leading to the change of land cover in TBMK area. The purpose of this research is to find out how much change of land cover in TBMK after the game park establishment, and the factors that affect the change. This study used spatial data method with SIG system and  Snowball Sampling technique in getting respondents’ samples. The result showed that TBMK in Cimanggung Adminiatrative Area had 468,66 ha land cover change in each closing type area from 1997 to 2017. The factors that cause the change of land cover in TBMK are the misuse of permission by PT. PMS, farmers activities in the area, unsettled area border, the lack of area guard and the socialization for the villagers, and the weakness of law enforcement
