Abstract

A part from its main product, meat, a slaughterhouse also produces by products and waste. The waste from slaughterhouse is categorized as organic waste, which is high in proteins, fats, and starches. This waste is potential as a source of pollutant. Slaughterhouse wastes can be treated by physically, chemically, and biologically.One of biological treatments is the use of water hyacinth (Eichhomia crassipes (Mart) Solm.), which is known to have an ability to remove organic and unorganic compound and heavy metals.The objective of this research was to evaluate the wastewater quality with water hyacinth treatment and to identify the interaction between action period and the density of water hyacinth during treatment. Four model ponds of 95 cm long x 50 cm wide x 50 cm high were used in this research. The parameters observed were pH, BOD5, and COD for the water quality. Each parameter was observed on day 0, 7, 14, 21, and 28, respectiv ely. The results of the research indicates that the water hyacinth had significant effect (P<0.01) on declining pH, BOD5 and COD of wastewater. The interaction between treatment and time observation lh showed significant effect (P<0.01) up to 28Â day of observation.

Abstract

Indonesia has great potentila in terms of community forest reaching more than 42 million ha. This potential, however, is still unwellmanaged so that is couldn't be a main source of farmer'sincome. In fact, according to argo ecology system; community forest can be cultivated by introducing promising intercrops in order to deliver more benefical effect. To overcome this problem, a reseach aiming to obtain potential models for community forest and spice crops intercropping pattern based on agro ecological zone was conducted from  August to December 2000. The reseach was carried out on 1.000 ha of partnership-based community forest (Paraserianthes falcataria) in Lengkong and Tegalbuled Sub district,sukabumi Regency, West Java province. the objectives of the research were achieved through survey method in gathering primary and secondary data. The data were analyzed by using Expert system Program (version 3.2.2.) and Framework of Land Evaluation. the results showed that the community forest explored was devided into 6 agro ecological zones with 5 recommended-landuses. Those are forestry (Zone I), palntation (Zone IIlax and IIbx), agroforstry (zone IIIax and IIIbx), and upland cultivation (Zone IVax2). According to microlimate condition under P.Falacataria trees, bushy pepper (Piper nigrum) is the most promising intercorps. Meanwhile, framework of land evaluation revealed that Zingiber officinale, Amomum cardamomum, and other Zingiberaceae species were marginally suiltable accompanied by heavy texture as the main constraint. In short, the potential models were (1) P. falactaria + A. cardamomum; (2) P.falactaria + P.nigrum. (3) P.falactaria + Z.officianale and (4) P.falactaria + Zingiberaceae (Curcuma xanthorizza, C.domestica, and Kaemferia galanga). Model (1),(3) and (4) would be more suitable on zone IIIax,IIIbx, and IVax2, whereas model (2) should be on zone IIIax nad IVax2.

Abstract

Besamya tingkat kerusakan tegakan eboni akibat eksploitasi hutan, kelihatannya makin diperburuk dengan kurang dilaksanakannya kegiatan penanaman kembali eboni di lapangan.Seandainya HPH telah melakukan upaya penanaman kembali pohon eboni, diperkirakan tingkat keberhasilannya masih sangat rendah atau mungkin belum sepadan antara luas areal yang ditanami dengan luasan areal bekas tebangan.Cara pembudidayaan tanaman menjadi sangat penting dalam pengusahaan pohon eboni ini. Penanaman pohon eboni tidak jauh berbeda dengan tanaman tropis lainnya. Saat ini kendala yang dihadapi dan perlu mendapat perhatian adalah belum dikuasai bagaimana teknologi benih, pengadaan bibit berkualitas serta apa hama penyakit pada eboni.Disajikan bagaimana pembudidayaan eboni secara praktis berdasarkan hasil penelitian, pengalaman dan pustaka pendukung, dan diharapkan dapat menambah informasi bagi praktisi lapangan atau pihak-pihak yang membutuhkan, sehingga keberhasilan penanaman eboni lebih terjamin.

Abstract

Gunung Halimun National Park (GHNP) is one of the remaining tropical forest in Java, still has high interaction with people who live in the surrounding areas.Eventhough there were some studies on ecology and ethnobotany in this area,it is still lacking of information on these subjects.This paper presented the results of ethno-ecology studies at several areas in GHNP such as East Halimun sector (around Gn.kendeng) and South Halimun sector (around Pangguyangan). The studies were carried out through vegetation analysis with Random Quadrats method and Participation method with interview technique.By these methods data were collected for the Important Value Index (IVI) and the Use Value Index (UVI) of species.These values showed that rasamala (Altingia excelsa), for tree stage, has the highest IVI and UVI but for the sapling stage the IVI is low. Kianak (Castanopsis acuminatissima) for tree and sapling stages the IVI is high but the UVI is low, while for maja (Magnolia macklottii), the UVI is high but the IVI is low for both tree and sapling stages. Based on these data, analyzed was done regarding the presence and the prospect of these species, in the context of the lifestyle of the villagers.

Abstract

Mangrove forests sequestrate and store a lot of carbon and are important to tackle climate change. However, much of these forests have been cleared dramatically and such clearings destroyed carbon sinks and released carbon into the atmosphere as carbon dioxide. The international climate agreements highlight Reduced Emissions from Deforestation and Forest Degradation (REDD+) as a key and effective option for mitigating climate change. To help making REDD+ a reality, an alternative approach is needed to measure above ground carbon stock quickly and accurately. Here, we link ground-based data collected from field measurement using belt transect method with satellite image data of the ALOS AVNIR-2. The objectives are to identify the characteristics of mangrove vegetation, to estimate the amount of above ground carbon stock, and to examine capability of vegetation indices of NDVI, SR, dan SAVI from the ALOS AVNIR-2 to estimate the amount of above ground carbon stock in mangrove. Results showed that the mangrove vegetation in Gugus Pulau Pari was relatively diverse and this forest contained above ground carbon between 4694.35 and 42841.25 kg/m2. The statistics analyses showed that there was no significant correlation between the vegetation indices of NDVI, SR, and SAVI with the amount of above ground carbon stock in tropical mangrove forest. In short, the vegetation indices of NDVI, SR, and SAVI from the ALOS AVNIR-2 were not sufficient to estimate the amount of above ground carbon stock in tropical mangrove forest.

Abstract

The destruction of mangrove forest constitutes one of the greatest threats to biodiversity and conservation of Ambon Bay.But,data and information of condition and potential of mangrove in Ambon Bay are lacking. We link three methods: remote sensing,Biological survey using transect, and sedimentation sampling to study the condition and potential of mangrove in Ambon Bay specially for biodiversity and sediment trapped. Remote sensing data showed that area of mangrove forest in Ambon Bay 34 ha and has declined dramatically in the past decade.The research recorded 8 species of mangrove; two are recorded as new species compared to the last survey.Based on data collected from four transects, mangrove forest in Ambon Bay is habitat for 8 species of mollusc and species of fish, crustacean, bird and epiphytes. Sediment analysis showed that mangrove forest 80% more effective to reduce sediment that come in to Ambon bay. Finally, the result indicated that condition of mangrove forest in Ambon Bay has been declined, nevertheless, have great potential for conservation of biodiversity and efficient in trapping sediment that come in to Ambon Bay.

The effect tesistence drought on the germination of 4 species of the Citrus seeds were studied under the laboratory conditions.The germination of the C.amblycarpa and C. aurantifolia seeds were still high at the moisture content less than 10 %. Meanwhile, the germination of C. grandis seeds were high at 10 % moisture content but the viability of the seeds were low at the moisture content below 10 %.Various methods of drying were investigated on the C. reticulata seeds. The best germination of the seeds were treated prior drying the seeds under the laboratory conditions. The germination of the seeds decreased rapidly under silica gel, dehumidifier and drying in the oven at 40°C.

Abstract

The observation of growth rate of flowery cod, Epinephelus fuscoguttatus, estuary grouper, E. tauvina and water conditions was carried out from December 2004 to June 2005, at the coastal waters of Kodek Bay, Malaka Village, West Lombok, West Nusa Tenggara Province (NTB). Early total weight of grouper fishes were 26.24 kg; at the end of study, it reaches 83.58 kg. The results shows that no significant difference on the growth rate groupers due to time of observation; while there is a significant difference on the gaining of body weight. The water conditions of surface layer and the 12 m depth, as well as temperature varied between 28.0-30.0 ° C, salinity between 30-35 %o, dissolved oxygen between 6.1-7.0 ml/I, transparancy between 3-12 m, current velocity between 0.014-0.071 m/sec; the pH between 8.2-8.7 and air temperature 26.5-27°C.The nutrient phosphate varied between 0.089-0.180 /ig.at/1, nitrite between 3.112-6.032 /ig.at/1. The of aspects of growth rate of flowery cod, estuary grouper and water conditions at the culture site are discussed.
