Abstract

This study aims to determine the effect of the area of Forest Fire and Deforestation Figures on Green House Gas Emission Level. This study uses descriptive quantitative research, with statistical analytical methods. The data source is processed with the Importance-Performance Analysis, so that the area can be used as a reference in reducing the level of greenhouse gas emissions. The provinces of South Kalimantan, South Sumatra and Papua are areas prone to fires which are suspected not to be affected by the high level of Indonesia's deforestation within and outside the Forest Zone, but there may be other factors that play a role in the emergence of the forest fires. It is suspected that among the factors that can be a trigger factor for high levels of forest fires that are directly related to the increase in the number of greenhouse gas emissions, namely the distribution of the peat deposits.

Abstract

Based on preliminary researches, stem and branchwood of Paraserianthes falcataria L. Nielsen were suitable as raw material for pulp and paper manufacture. For the whole tree the highest proportion of bark was found in branches and the top of the tree with a value ranging 20 – 35%. Up to now, the pulp industries have spent money to remove bark of P. falcataria branch before pulping. The objective of this study was to know the suitability of branches including bark as raw material for pulp and paper manufacture. Samples were determined for fiber dimension and its derivation. Screened chips were cooked with the Kraft process. Liquor-to-wood-ratio was 4 : 1. Chemical charge was 13.3% NaOH and 6.7% Na2S. The temperature was raised from room temperature to 170 oC for 90 min and kept at this temperature for 90 min. Pulp was washed; then kappa number, screened and rejected pulp, residual of black liquor were determined. Research results showed that pulp branchwood with bark has the values of screened pulp yield, alkali consumption, and kappa number 46.91%; 9,57; and 25.63, respectively. It paper product has the values of breaking length, burst factor, stretch, tensile strength, and opacity 9.94; 83.80; 3.57%; 1,733.34; 6.33 kN/m, and 92.85%, respectively. Based on those results, paper from branchwood with bark meets requirement for book, mimeograph, and photocopy papers.

Abstract

A study on the type and phytoplankton diversity in the Koto Panjang Dam, Kampar, Riau , was conducted on May-October 2009. There were 6 stations, in the Batu Basurat, Koto Tuo , Tanjung Alai, Batang Mangat and Rantau Berangin villages and in the river mouth of the Kampar River. Parameters measured were water quality in general and phytoplankton diversity. In each station, water and phytoplankton samples were taken in the surface, 2.5 secchi depth and in the bottom of the dam. Sampling was conducted once/ month. Types, abundance and diversity of phytoplankton were analyzed. Results shown that there were 17 species of phytoplankton that were belonged to 4 classes, namely Bacillariophyta (6 species), Chlorophyta (5 species), Crysophyta (3 species) and Cyanophyta ( 3 species). There were no dominant species in the research area, good diversity index (2.13-2.71) and high similarity index (0.81-0.94). Based on data obtained, it can be concluded the water quality in the Koto Panjang Dam is suitable for supporting the life of phytoplankton.

Abstract

AbstractMangrove forests are one of the coastal ecosystems that have significant ecological andeconomical value. This ecosystem is known for its role in protecting coastal environmentagainst waves and storms as well as supporting the life of numerous marine organisms.However, the increase of human population and the need to expand settlements and industrialareas makes many mangrove ecosystems vulnerable. Objectives of this research were tomeasure the change of mangrove’s area of Sidoarjo district using satellite imagery datafrom different period and to classify the area based on their vegetation density. To measurethe density of mangrove vegetation NDVI index were employed. Results of Landsat ETM-7(acquisition 2002) and ALOS (acquisition 2010) analysis showed that mangrove’s area ofSidoarjo district has declined intensively. Illegal logging and land use changing weresuggested to be the main cause of the destruction of mangrove forest in this area. In order toprevent further destruction of the mangrove’s area, local authorities have implemented UUNo.27 where heavy penalties are implied for illegal logging.

Abstract

Increased consumer awareness of safe vegetable products free of chemical residues and environmentally friendly has encouraged the development of organic farming. However, significant reduction in crop yields in the early phase of the application of organic farming has hindered the development of the system.This study aims to determine the combination of manure and NPK fertilizer that provides vegetables yields no different from conventional farming in order to determine the strategy of transition from conventional farming to organic systems..The study was conducted in Bangli village, Baturiti district, Tabanan regency, Bali. A randomized completely block design was used in this experiment with six treatments of combination manurewith NPK fertilyzer and three replications. As an indicator plant is caisim(Brassica Chinensis L). The results showed that the application of manure 20 tons ha 1 (organic farming)resulted in the growth and yields of caisim are significantly lower than conventional systems(100 % of NPK dosage). Meanwhile, theapplication of 10 tons ha manure combined with a 50% of NPK fertilizer dosage to produce caisin are not significantly differentwith conventional farming, and soil properties such as organic C, total-N, available P, and exchangeable K no different with an organic farming system.Thus, this treatment can be used as a transition strategy from conventional farming to organic systems

Abstract

AbstractSeven Brassica napus cultivars were field tested to find out their adaptability andproductivity in tropical dry land environment. The aim of this research is to identifypotentially high oil yielding and agronomically stable Brassica napus genotypes as a newsource of biodiesel in Indonesia. Crop evaluation includes germination rate, plant height,number of leaves and stomata, flowering time, harvesting time, seed yield and oil content.Oil extraction using ’cold pressing’ technique were trialed. Results show that all genotypeshave good adaptability, therefore can be an alternative for biodiesel sources in Indonesia.Variation occurs on plant height, number of leaves, flowering time, seed set and oil content.‘‘Tanami’’, ‘‘Trigold’’ and ‘‘Trilogy’’ has similar performance, short plants, high pod set andearly flowering, while other cultivars have vigorous, tall plant habit but lower seed set.Some cultivars have an early flowering type while others has intermediate or late flowering.Pod set was excellence; however, seed set was low due to pest attack, namely Diamondbackmoth. Oil content of the seeds ranging from 2.6 to 11 %. In conclusion, B. napus areadaptable in dry land environment. Further study is needed to maximize seed productionand oil content.

Abstract

Sampah merupakan sesuatu yang tidak dibutuhkan/tidak dipakai/tidak bemanfaatbagi manusia. Akibat menumpuknya sampah dapat menimbulkan masalah kesehatanterutama penyakit bawaan sampah seperti; diare, ISPA, penyakit kulit, malaria, DBD, baikdi musim hujan maupun musim kering. Kondisi seperti inilah yang sedang terjadi dilingkungan masyarakat yang bermukim di sekitar TPA Tibar, Timor-Leste karena kurangnyaperhatian dari pemerintah dan juga masyarakat setempat. Oleh karena itu, perlu adanyasuatu konsep penanganan sampah dengan mengubahnya menjadi barang yang mempunyainilai ekonomis dan menjadi material yang tidak membahayakan kesehatan masyarakatsebelum dibuang ke tempat pembuangan akhir  sampah. Untuk itu, perlu adanya kerjasama secara kolektif antara pemerintah, LSM dan masyarakat guna mendukung berjalannyaproses penanganan sampah. Selain itu, tujuan dari penelitian ini adalah untuk mengetahuipengaruh reduce, reuse, recycle secara parsial terhadap kesehatan masyarakat. Dalampenelitian digunakan metode analisis kuantitatif dengan pendekatan cross sectionaldimana data yang menyangkut variabel bebas atau resiko dan variabel terikat atau variabelakibat, dikumpulkan dalam waktu yang bersamaan. Hasil penelitan menunjukkan bahwaX1 atau reduce mempunyai nilai Sig Wald 0, 004 < 0,05 sehingga menolak H0 atau yangberarti Reduce memberikan pengaruh parsial yang signifikan terhadap kesehatanmasyarakat. Artinya semakin menurunnya kualitas masyarakat melakukan reduce semakinmenurun juga kesehatan masyarakat, X2 atau Reuse mempunyai nilai Sig Wald 0,009 <0,05 sehingga menolak H0 atau yang berarti Reuse memberikan pengaruh parsial yangsignifikan terhadap kesehatan masyarakat artinya semakin menurunnya masyarakatmelakukan reuse semakin menurunnya juga kualitas kesehatan masyarakat, X3 atau Recyclemempunyai nilai Sig Wald 0,020 < 0,05 sehingga menolak H0 atau yang berarti Recyclememberikan pengaruh parsial yang signifikan terhadap kesehatan masyarakat. Artinyasemakin menurun masyarakat melakukan recycle semakin menurunnya juga kualitaskesehatan masyarakat. Jadi secara parsial reduce, reuse, recycle berpengaruh signifikanterhadap kesehatan masyarakat.
