The species composition and forest structure of Taman Hutan Raya Bukit Soeharto - East Kalimantan were investigated using transect method through systematic sampling with random start design. During data collection,5 transects of 20 m width and 1 km length of each in Wanariset Semboja forest complex and 10 transects in Pusrehut UNMUL and Protection Forest areas were established. The study shows that species richness of trees in those three forest complexes are relatively similar, however, the regeneration stage in Pusrehut UNMUL forest complex is relatively higher than those in another two areas. Medang (Litsea firma), Acacia (Acacia sp.), and Mahang (Macaranga gigantea) are dominant tree species in Wanariset Semboja, Pusrehut UNMUL and Protection Forest areas, respectively. Mahang (M. gigantea) as pioneer species is also commonly dominated forest regeneration in Taman Hutan Raya Bukit Soeharto. Based on tree’s diameter distribution, those forests show balanced uneven-aged forests in which the large amount of trees are concentrated in the height class of 10 to 29 m. Species diversity of those forests are relatively high (H > 2.5) either for seedling, sapling, pole or tree growth stages, however, those forests show different plant communities (IS < 70 %).

Each input of economic development of marine and fisheries activities able to be measured/evaluated its works more interrelated with its input, output, outcome and its impact related with its contribution in national economics matters. Recently, the position of marine and fisheries in national development and economic has not at the position which able to be evaluated its works yet since formally it has not be inserted in national economic/ Gross Domestic Products (GDP). In other hand, the establishment of marine and fisheries department that has get fund from National budget (APBN) to manage and facilitate of marine and fisheries management able to be measured for its impact for national economics matters. The aimed of this research is to analyze the factors related with above matters consists of : VA, sub-sector of marine potential, perception of official and capacity building.The result of this research shows that inclusion of marine and fisheries sector in Gross Domestic Products (PDB) able to do that are : firstly, separate fisheries sub-sector from agriculture sector and then put in the marine and fisheries sector, secondly, potential of marine resources has high economics value to product such as coastal water has NPV USD 69.5 and IRR 30%. Thirdly, placement of marine and fisheries sector in PDB has supporting from related official but it needed to be supported by rearrangement of DKP structure organization.

Urban pests like cockroaches, mosquitoes, and flies can transmit human diseases that cause health problems in the society. Currently, mosquito is main insect that transmit very deadly diseases, such as dengue fever, cikungunya, and malaria. Prevention of those diseases is generally focused on controlling the vectors in various ways, such as fogging, the use home pesticides, sanitation, use of mosquito repellents, electric rackets, and other traditional ways developed by the community (mosquito Titiek Siti Yuliani; Hermanu Triwidodo; Kooswardhono Mudikdjo; Nurmala K.

Urban pests like cockroaches, mosquitoes, and flies can transmit human diseases that cause health problems in the society. Currently, mosquito is main insect that transmit very deadly diseases, such as dengue fever, cikungunya, and malaria. Prevention of those diseases is generally focused on controlling the vectors in various ways, such as fogging, the use home pesticides, sanitation, use of mosquito repellents, electric rackets, and other traditional ways developed by the community (mosquito net, gauze, water). The purpose of this study was to describe the relationship between characteristics of peoples live in Jakarta (based on age, sex, education, and income level) to their behavior in using home pesticides and to know the impact of those pesticides to peoples and pets live in their houses. Research sites were purposively directed to the areas that were appropriate with the substances and purposes of this study. Interviewed was conducted to the respondents (housewives) and inspection of their houses were also conducted to classify their houses as clean, moderately clean, and dirty or slum. Based on a survey to 155 respondents, it was revealed that respondent characteristics as well as their house conditions influenced the behavior of those respondents in choosing home pesticides. Majority of housewives (28.21%) use liquid pesticides which were contains the active ingredient of cypermethrin 0.4 g/l, imiprotrin 0.32 g/l, and transflutrin 0.2 g/l. In addition, 47.26% of them ignored the instruction written on the label in using those pesticides. Awareness of those respondents was still low in terms of dumping the package of pesticides; 96.64% of respondents dumped pesticides to the dumpster near their houses. Commercial advertencies from electronic media, especially TV, influence half of the respondents (52.74%) in choosing home pesticides used. In general, it can be summarized that the awareness of respondents in using home pesticides were still low. Most housewives did not know the danger of those chemicals and how to use it properly. Only 38.46% of them used non-chemical methods, such as insect net. Key words: home pesticides, active ingredient, urban pest, housewife, the environment

Environmental conflicts in protection forest mostly caused by issues of scarcity, negative externalities, structural unbalance, and different viewpoint of people on value of forests. In many cases, forest governance creates overlapping policies regarding with these issues that may generate conflict escalation; this occurs in Register 45B of Protection Forest Zone in Lampung Province. This research aimed to study (1) factors those affecting (escalation of) conflict, (2) conflict management style Gamal Pasya; Kooswardhono Mudikdjo; Sediono M.P.

Environmental conflicts in protection forest mostly caused by issues of scarcity, negative externalities, structural unbalance, and different viewpoint of people on value of forests. In many cases, forest governance creates overlapping policies regarding with these issues that may generate conflict escalation; this occurs in Register 45B of Protection Forest Zone in Lampung Province. This research aimed to study (1) factors those affecting (escalation of) conflict, (2) conflict management styles manifested by parties/disputants, (3) polarization of parties refer to the conflict roots they face, and (4) settlement options that parties willing to take referring to alternative dispute resolution (ADR) options. Research implementation and analysis carried out by using pathway analysis and pairwise comparison analysis-scheffe test. The research found that conflict escalation was mainly caused by decision to convert forest land use. Conflict management styles are collaborative and compromise. Polarizations of parties refer to similarities on interests. All parties willing to take negotiation and/or facilitation as ADR options to settle disputes. Key words: conflict, environment, forest, resolution

Agricultural land conversion is considered as one of an important issus in the developing areas. In spite of theimportance of informations on the quantity and the rate of land conversion as the basis of formulating the agricultural landconversion policy, those informations are limited. This research was conducted at Lembang and Parongpong Sub-District,Bandung District. The objectives of research are to identify the rate of agricultural land conversion and to measure thedynamic change of land use. Land use in 1992 and 2002 was evaluated by interpretating the result of 1992 and 2002 landsatimage using Geographic Information System (GIS) program. Shift Share analysis was conducted to know the dynamic changeof land use. Results of the study indicated that land conversion at Lembang and Parongpong Sub-District during the period of1992-2002 (ten years) about 3,134.49 ha (25%) or 313.5 ha (2,96%) per year. Forestland reduced the most, from 5,470 ha in 1992 to 1,746 ha in 2002 or reduced about 3,732.12 ha (68%) in ten years. While area of the bush was increased about2,780.20 ha (1,326%) during the same period, from 210 ha in 1992 to 2,990 ha in 2002. Low land was decreasedfrom 252 hain 1992 to 95 ha in 2002, up land was decreased from 3,856 ha in 1992 to 2,736 ha in 2002, mix farming was increasedfrom2,491 ha in 1992 to 4,358 ha in 2002, resettlement was increased from 359 ha in 1992 to 1,612 ha in 2002, bare wasdecreasedfrom 1,115 ha in 1992 to 217 ha in 2002, lake was decreasedfrom 52 ha in 1992 to 50 ha in 2002.
