Abstract

The growth of the dairy industry in Indonesia is expected to be an attraction for the local farmers. The increasing number of breeders will have a negative impact on the increase of waste generated.Waste from the farm business can be a solid waste, gas and liquid waste. Animal husbandary waste can be processed to produce biogas as an energy alternative to oil burner and premium drive electricgenerators. From the measurement of CH4 content ranged from (56.67 - 62.8 %), while the CO2 content ranged between (36.36 - 42.64 %). This value is between methane and carbon dioxide content of the theoretical limit. Gasbio volume generated during the 24 hours ranged of 4.218 - 6.198M3, or the average of the gas produced as much: 5,096 M3 per day. Electricity generated = 3.822 kWh. Electricity power genset of 500 watt can burn for 7 hours. The results of laboratory analysis of sludge solids can be seen that the C / N ratio is still relatively high at 42.6, whereas the C / N ratio, which allowed ranged of 15-25. The C value is very high due to the organic composting process is too short, the element N is very low because the nitrogen is still in the complex chain that required the administration of N fastening bacteria such as : Azotobacter, Azotomonas, Pseudomonas.Keywords: cattle manure, biogas, energy listrk, compostAbstrakPertumbuhan industri susu olahan di Indonesia diharapkan akan mampu menjadi daya tarik bagi peternak lokal. Meningkatnya jumlah peternak akan berdampak negatif terhadap meningkatkanlimbah yang dihasilkan. Limbah dari usaha peternakan tersebut dapat berupa limbah padat, gas dan limbah cair. Limbah peternakana dapat diproses untuk menghasilkan biogas sebagai energi alternatif pengganti minyak kompor dan premium menggerakan generator listrik. Dari hasil pengukuran kandungan CH4 berkisar antara (56,67 – 62.8%), sedang kandungan CO2 berkisar antara (36.36 – 42,64%). Nilai tersebut berada diantara kandungan metan dan karbon dioksida pada batas secara teori. Volume gasbio yang dihasilkan selama 24 jam berkisar antara (4,218 - 6,198) M3,atau rata-rata gas yang dihasilkan sebanyak : 5,096 M3 perhari. Listrik yang dihasilkan = 3,822 kWh. Genset dengan daya 500 Watt maka listrik bisa menyala selama 7 jam. Dari hasil analisislaboratorium terhadap padatan sludge dapat diketahui bahwa C/N ratio tergolong masih tinggi yaitu 42,6, padahal C/N ratio yang diizinkan berkisar antara 15 – 25. Hal ini disebabkan karena Corganiknya sangat tinggi akibat proses komposing masih terlalu singkat, unsur N sangat rendah karena nitrogen masih dalam rantai yang kompleks sehingga diperlukan pemberian bakteripenambat N, diantaranya adalah: bakteri Azotobacter, Azotomonas, Pseudomonas.

Abstract

The interaction between species and species diversity with their growing habitats are essential in the conservation of species. This study deals with the diversity and conservation of seaweed (marine macro-algae) with the emphasis on substrata habitats (sandy and rocky shores) and seasonal conditions (rainy and dry seasons). The study was carried out on the Warambadi seashore of Sumba Island. The t-test analysis showed that the “species diversity index of algae” (H’) on both sandy and rocky substrata did not significantly different. The (H’) during both rainy and dry seasons on different substratum (sandy and rocky substrata) did not show any significant differences. The two-way anova analysis recorded that the (H’) and the number of algae species were not affected by the differences of both substrata and seasons, but it was significantly affected by the interaction between the types of substratum and season. The study also reported that the types of substrata and seasons affected the (H’) of Chlorophyceae but not by of their interaction, and the (H’) of Rhodophyceae was affected by the types of substratum and season but not by their interaction. Moreover, the types of substratum and season affected the (H’) of Phaeophycea, but their interaction did not affect such diversity index. Substrata and seasonal phenomenon also indicate that the types of substratum, season, and their interactions affected the number of species Chlorophyceae, Rhodophyceae, and Phaeophyceae.Keywords:  seaweed, diversity, conservation, substrata, season

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

Pada umumnya peneliti menentukan status kualitas perairan menggunakan data yang diperoleh dengan plankton-net. Data tersebut tidak menceminkan kepadatan dan struktur komunitas fitoplankton yang sebenarnya. Oleh karena itu data tersebut kurang layak untuk menganalisis status kualitas perairan. Artikel ini menyampaikan hasil kajian kelimpahan fitoplankton di perairan tawar dan laut, yang diperoleh dengan dan tanpa menggunakan plankton-net. Kepadatan yang diperoleh dengan planktonnet menghasilkan nilai yang jauh lebih kecil dari kepadatan yang diperoleh tanpa menggunakan plankton-net. Ini mengisyaratkan bahwa untuk menganalisis status kualitas air, lebih layak menggunakan data yang diperoleh dengan tanpa plankton-net kata kunci: fitoplankton, plankton-net, nutrien, eutrofikasi, struktur komunitas.AbstractIn general, researchers determine the status of water quality using data obtained with a plankton-net. The data do not reflect the density and the actual structure of phytoplankton communities. Therefore, the data is not feasible to analyze the water quality status. This article present the results of the study the abundance of phytoplankton in freshwater and marine, which obtained with and without using a plankton-net. Density obtained with a plankton-net produce values that are much smaller than the density obtained without using a plankton-net. This implies that in order to analyze the status of water quality, is more feasible to use data obtained with the no-net plankton key words: phytoplankton, plankton-net, nutrients, eutrophication, the community structure.

Abstract

Tampomas mountain areas can be divided 2 types of aquifer : volcanosediment aquifer and sediment aquifer. Volcano sediment aquifer is afree aquifer sedimentation, because there was not impermeable rockexisting under or bellow it, this aquifer also known as shallow or surfaceaquifer. Sediment aquifer is a depressed aquifer where the water flowalong the sandstone layer which covered by claystone and water flowthrough the pore. This sediment aquifer are deep aquifer. Ground waterat sumedang area can be divide as : ground water on volcanic quartersedimentation and ground water on consolidate rock.The type of water source at the reaserch area can be devide into 3 ways: Depressed water resources formed by land surface which is cuttingthe watter table, Shear water source which formed by the crack / shearstructure or sesar path, and contact water source which shown at thetertiery rock (impermeable) and quartery rock (permeable).This reaserch using geofisical methode Imaging Resistivity to resultinterpretation that on the south Tampomas Mountain predicted had 4aquifer potention resource (A,B,C,D), whith aquifer thickness vaariatedfrom (5-15)m, (30-50)m and more than 50 m. Several water sourcesurface cases found in this reaserch area at 20-30 m depth which predictas the water table. This indicated there are very large aquifer at 500 mlevel and assume this level as a potential places for ground water existat the south Tampomas mountain.

Abstract

The end of municipal solid waste operations is landfill. Almost all of the Indonesia city’s landfills use the open dumping system. Generally, wastes dumped in the landfill are dominated by organic materials that potentially used for cow feeding. So that, in some landfills there are cow pasturing with the low cost operation related to the free feeding materials. According to UU No 18/2008, in the year of 2013 open dumping landfill is prohibited operate changed by sanitary landfill. Related to this change, the cow pasturingin landfill will be affected. So that the cow pasturing in landfill need to be assessed in the aspect of waste reduction, economic values, landfill operation, social conflict, and safety cow meat. The goals of this study are assessing positive and negative impacts from cow pasturing in the Piyungan Landfill, Yogjakarta. Research methods used are references study, interview, counting the cow and direct investigation of landfill operation. This study concluded that cow pasturing in landfill has positive impacts for waste reductionand increasing economic level of people live in surrounds of landfill. Unfortunately, the cow pasturing has also negative impact such as disturbing daily landfill operation, high potent social conflict during landfill rehabilitation, and high content of some heavy metals in the cow organ. Based on those impacts, the policy of the cow pasturing has to be reviewed because of the importance of sanitary landfill operation in the near future andthe issue of safely consuming meat free from heavy metals.Key Words: landfill, waste, cow pasturing
