Abstract

Picrasma javanica is one of the medicinal plants that has an anti malaria potency,it is belonging into Simaroebaceae family. The aim of this research is to know the effect of GA3 on broken dormancy of P. Javanica seed after storaged in the various temperature to enhance and increased seed germination. The experiment was carried out in the Macropropagation Laboratory, Cibinong Science Center, Research Center for Biology,LIPI, using a Complete Randomized Design with two factors in three replication.The first factor is condition of storage i.e room (28 ± 10 C, RH 80%), incubator (200 C,RH 90%), incubator ( 50 C, RH 95%) dan deep freezer (- 200 C, RH ). The second factor is long of storage i.e. 1,2,3,4,5 and 5 months. GA3 100 ppm was used for broken seeddormancy. The result showed that there was no interaction between temperature and long of storage. GA3 solution can be broken on seed dormancy before and after storage in the various temperature excepted in deep freezer ( – 200 C, RH 65%), there are no seed germinate since 1 month storage. P. javanica seed that storage in incubator 50 C is the best method and after 5 months the germination percentage is still high (73,3%) with GA3 but only 18,33% without GA3. On the other treatments the germination percentage is less than 50%. The highest germination value (14,1) that was recorded in the seeds that storage in incubator (200 C, RH. 95%).Key words: GA3, dormancy, temperature, long of storage, seed , P. javanica

Abstract

ABSTRACTResearch on modeling and hydrological services in forest and watershed (DAS) ecosystem protection is still very little done in Indonesia; therefore, this research will be very useful for related stakeholders, since the purpose of the research will answer two problems, namely:  (1) what factors can significantly affect the hydrological services in the protection of forest and watershed ecosystem both in the upstream and downstream areas DAS and (2) establish the economic value of hydrological services in upstream and downstream watershed areas. The results of the study indicate that: water consumption in the downstream area is strongly influenced by: (a) family expenditure at 96.5% significance level, (b) family income at 80.7% significance level, and (c) work experience at significance level 72.4% with R Square Model 53.00% validation test. Water consumption in the upstream area is influenced by: (a) the cost of water storage at the significance level of 94.4%, (b) the age of the respondent at the significance level of 71.4%, and (c) the distance to the resource (location water springs) water at a significance level of 55.7% with a validation test of R Square model 97.30%. The research in this study at the same time responds to the existence of hydrological services as a model of protection of forest ecosystems and integrated and comprehensive watersheds from upstream - downstream; economic value of ecosystem services in forest and watershed protection in the form of hydrological services, which is the value of choice from the utilization of water resources or as hydrological services, which is Rp. 1.272.211.617.235. The value of this choice is basically the sum of the Consumer Surplus in the downstream area of Rp. 830,837,758,433 and the value of Producers Surplus in the upstream area of Rp. 441.373.858.801.Keywords: hydrological services, ecosystem protection, economic value of hydrological services, upstream-downstream watershed areas, producers surplus, consumer surplus.ABSTRAK Penelitian tentang pemodelan dan jasa hidrologis dalam perlindungan ekosistem hutan dan Daerah Aliran Sungai (DAS) masih sangat sedikit dilakukan di Indonesia, sehingga penelitian ini akan sangat berguna bagi pemangku kepentingan terkait, karena tujuan penelitian akan menjawab dua masalah, yaitu: (1) faktor apa yang dapat secara signifikan mempengaruhi jasa hidrologis dalam perlindungan ekosistem hutan dan DAS baik di DAS hulu maupun di DAS hilir;  dan (2) menetapkan nilai ekonomi jasa hidrologis di kawasan DAS hulu-hilir. Hasil penelitian menunjukkan: Konsumsi air di daerah hilir sangat dipengaruhi oleh: (a) pengeluaran keluarga pada tingkat signifikansi 96,5%, (b) pendapatan keluarga pada tingkat signifikansi 80,7%, dan (c) pengalaman kerja pada tingkat signifikansi 72,4% dengan uji validasi Model R2 53,00%. Konsumsi air di daerah hulu dipengaruhi oleh: (a) biaya penyimpanan air pada tingkat signifikansi 94,4%, (b) usia responden pada tingkat signifikansi 71,4%, dan (c) jarak ke sumber daya air (lokasi mata air) pada tingkat signifikansi 55,7% dengan uji validasi Model R2  97,30%.

Abstract

Air limbah pabrik pembuatan makanan kecil coklat batangan yang berasal dari proses pencucian alat cetakan diketahui banyak mengandung gula, protein dan lemak atau minyak. Suatu permasalahan yang sering ditemui dalam proses lumpur aktif pada air limbah yang mengandung kadar organik dan senyawa nitrogen tinggi adalah terbentuknya nitrogen dalam bentuk nitrogen terokdidasi seperti nitrat dan nitrit. Penelitian ini dilakukan untuk mengetahui pengaruh waktu aerobik dan anoksik dalam menurunkan kadar COD terlarut dan nitrat.Dari hasil percobaan didapatkan beberapa kesimpulan antara lain yakni makin besar periode aerasi dalam satu siklus waktu bioreaksi aerobik-anoksik sama maka makin besar pula penyisihan nitrat-N, dan makin besar produksi lumpur. COD terlarut akhir bioreaksi juga makin kecil bila periode aerasi lebih panjang walaupun total bioreaksi aerobik-anoksik sama. Waktu yang diperlukan untuk mencapai kondisi anoksik dari kondisi aerobik untuk masa aerasi 2-4 jam kurang dari 30 menit, sedangkan periode aerasi 5-6 jam butuh waktu < 40 menit. Penurunan nitrat- N dibawah baku mutu 10 mg/l, untuk periode arasi 2 – 4 jam juga < 30 menit dan periode aerasi 5 – 6jam butuh waktu < 40 menit.

Abstract

The objective of this research is to study the influence of small-scale sago processing industry to standard quality of Ciheuleut river water in Cibuluh Sub-district, District of Bogor Utara, and City of Bogor. The method used is to analyse the water in laboratory and subsequently the result is compared to standard quality of tapioca industry. Response of community in the area regarding this sago processing industry is gathered by performing interview in the form of questionnaire (number of community response is 35). Water samples used for water analysis are from 4 locations. They are water beforeflowing into the processing unit (A), water after filtration (B), process disposal water collected 1 m apart from filter (C) and discarded water that flows into river (D). Water analysis applied utilizes chemical analysis that includes pH, COD, BOD, DO, turbidity, cyanide and TSS (Total Soluble Solid) parameters. Laboratory analysis shows that location B has turbidity level that exceeds the standard quality required. Result of hypothesis test shows that hypothesis zero (H0) acceptable and alternative hypothesis rejected. It means water disposal waste of sago processing industry does not alter thequality of water disposal. Community feel disturbed (46%) on the existence of sago processing industry. The disturbance consists of liquid waste (20%), unpleasant odour due to solid waste (51.1%), and noise (22.9%). Unpleasant odour due to solid waste occurs during rainny season. 60% of responses say that water disposal of sago processing industry leads to river turbidity; whereas 40% thinks that it does not make any difference.River turbidity brings about itchiness (28.6%) while 68.6% says it does not make any difference. 71.4% of responses show that the existence of sago processing industry is beneficial to the community.

Abstract

Microalgae as biomass are a potential source of renewable energy and they can beconverted into energy such as biofuel oil and gas. This paper presents a briefreview on the main conversion process of microalgae becoming energy. Sincemicroalgae have high water content, then not all biomass energy conversion processescan be applied. By using thermochemical process it can be produced oil and gas,and by using biochemical process it can be produced ethanol and biodiesel. Theproperties of microalgae product is almost similar to offish and vegetables oil andtherefore it can be considered as a substitute of fossil oil.
