Abstract

Coconut water and rotten banana fruits are commonly found in traditional markets as organic wastes. One way to overcome the problems caused by these organic wastes is to convert these unuseful matter into an important and economically useful matter by using them as components of tissue culture media. One important commodity that is usually propagated by tissue culture is Phalaenopsis orchid type 229 (Phalaenopsis amabilis). Therefore, it would be more benefit to substitute the expensive chemicals with organic wastes such as coconut water and banana puree.In this experiment, addition of coconut water and banana pure to the minimum media containing commercial fertilizer red Polyhyponex, sucrose and commercial agar did not show any inhibition of Phalaenopsis orchid plantlet growth. This probably caused by sufficient macro and micro nutrients provided by those organic matter and Polyhyponexfertilizer. Moreover, addition of 100 mL/L of coconut water and 100 mg/L banana puree gave the optimum leaf and adventitious shoot formation. On the other hand, addition of 150 mL/L coconut water gave the optimum height and root formation. In this case,growing Phalaenopsis orchid plantlet should be done in 2 subculture period. The first subculture is to obtain maximum amount of leaf and shhot formation while the second subculture is to obtain optimum height and root formation.Key words : Waste, coconut water, banana puree, tissue culture, Phalaenopsis orchi

Abstract

The evaluation of agricultural commodity zoning is implemented on tidal swamp area in Batola District, South Kalimantan Province . In fact, the quality of land varies from one place to the others due to the presence of limiting factors in it. Therefore a study of land suitability is essentially needed before utilizing land for cultivation. The method used in the study refers to FAO procedure and Soil Research Institute as well. A brief explanation of land resources evaluation, land suitability and commodities zoning for food crop,horticulture, and plantation crop is presented in the methodology. Then, the results of land characterization and suitability classification in Batola District are discussed, so that,more derstanding in respect to land properties and quality is derived. There are threegroups of soils is found the study area, namely peat soils, marine soils and pluviatile soils. By nature those soils have several limiting factors, i.e. drainage (flooding), acidity,sulphate potential, salinity, and low fertility. The highest grade of suitable land in Batola is only S2 (moderately suitable), and the largest area is classified as S3 (marginally suitable) for all analyzed cultivation. Since, the results of land suitability were derived then the commodities zoning were conducted. Water managing, liming, and fertilizing are definitely needed for land development and land reclamation.Key words: land evaluation, commodities zoning, GIS, agriculture

Abstract

Water waste in Palm Oil Mill (POM) is not effectively utilized yet. Before waste water discharge from POM, the waste water is processed by an aerobic treatment in several ponds to decrease the influence of organic matter. Methane gas generated in the anaerobic ponds is a Green Gas House giving a contribution to global warming impact. In Palm Oil Mill of Sei Silau located in North Sumatera, the potential generated methane gas in two anaerobic ponds has been investigated using measurement of Chemical Oxygen Demand (COD) of waste water in the sites. Based on the potential generated methane gas, the reduction of GHG emission is calculated, and the feasibility of the project as CDM project was evaluated.Keywords : Pabrik Kelapa Sawit, gas metana, gas rumah kaca, proyek CDM (CleanDevelopment Mechanism),, COD (Chemical Oxygen Demand)

Abstract

Fotobioreaktor adalah suatu alat yang dipergunakan dalam memproduksi mikroalga yang dapat dipegunakan untuk menyerap CO2. Kultur mikroalga pada fotobioreaktor adalah salah satu upaya untuk mengurangi emisi CO2 di atmosfer, yang merupakan bagian dari teknologi CCS (Carbon Capture and Storage). Fotobioreaktor dijalankan dengan sistem batch dalam waktu 1 siklus hidup mikroalga (10 – 12 hari). Pada tahun 2008, PTL-BPPT telah mengembangkan fotobioreaktor skala batch dengan volume 50 L untuk mengurangi emisi CO2. Dalam perancangan ini perlu dilakukan pula ujikebocoran sistem fotobioreaktor agar hasil yang dicapi benar-benar optimal. Tetapi karena kurangnya jenis mikroalga yang diujikan serta keterbatasan isolat murni adalah beberapa kendala yang dihadapi pada kegiatan perancangan ini. Dari hasil perancangan ini diharapkan didapat informasi perancangan fotobioreaktor dalam skala besar dan jenis mikroalga yang dapat menyerap emisi CO2.Kata kunci : Mikroalga, fotobioreaktor, emisi CO2
