Abstract

Vegetable cultivation is livelihoods for side Lake Batur communities, Kintamani, Bangli. Hilly natural conditions with a soil texture influenced by the eruption of Mount Batur, 900 m above sea level, and 900-3500 mm high rainfall, causing this region is very suitable for the cultivation of various vegetables, including shallot. One effort to meet the high demand for shallots is that efforts are made to improve cultivation techniques, including fertilizing to improve yields. In modern agriculture, the use of fertilizer is absolutely essential to trigger the level of crop production. The aims is to analyze the combination effect of using of inorganic fertilizer (ZA fertilizer) and organic fertilizer (compost fertilizer) on shallot vegetable cultivation systems on the content of pollutants, N nutrients and onion crop yields on the shores of Lake Batur, Kintamani District, Bangli Regency. The study using RBD with two factors where factor I: provision of organic fertilizer is leaf compost made aerobically (O), consisted of 3 levels, namely: O0 = 0*, O1 = 5* and O2 = 10*and factor II: the application of inorganic fertilizer namely ZA (S) fertilizer, consisted of 3 levels, namely: S0 = 0**, S1 = 50** and S2 = 100**, each repeated 3 times. The parameters observed were the growth and yield of shallots as well as the content of Pb, Zn, Cu and N nutrients in the soil. The nutrient content (N) in the soil, when using chemical fertilizer ZA and compost organic is not significantly different, as well as the results of onion plants, while the content of Pb, Zn and Cu on the use of chemical fertilizer ZA and organic compost, very real different. The highest soil Pb content in S2O1 treatment is 30.07***, the highest soil Zn content in the S2O1 treatment was 28.24***, and the highest soil Cu content in the S1O2 treatment is 17.22***. *= tons/ha **= kg/ha ***= mg/kg Keywords: compost; contents Pb; Zn; Cu of soil; shallot; ZA.

Abstract

Pakerisan watershed is used by the people for various purposes to meet the daily needs for water and it is also for irrigation water. The aim of research was to determine the water quality related to human activities and the pollution index. Water sampling was conducted in the nine sample points i.e. upstream of two sample points, in the middle of four sample points, and in the downstream of three sample points. Sampling was done by purposive sampling. Determination of water quality was carried out by comparing the measured data of each parameter of water with the value of quality standards based on the Bali Governor Regulation Number 08 of 2007, while the definition of the status of water quality was done by the pollution index method. The results showed that the activities that affect the water quality physically, chemically and biologically at the upstream to downstream are farming activities, settlements, tourism and trade. In the upstream showed no parameters that exceeded the quality standards, the variables of BOD, COD, phosphate, fecal coli and total coli exceeded the quality standards and in the downstream, the BOD, fosfat and fecal coli exceeded the quality standards. The pollution index found in the upstream region good condition, whereas in the middle was classified as heavily polluted until the downstream was lightly polluted.

Abstract

Development of the population and the increasing demand for health services has led to the increase in the number of hospitals, both government hospital and privet hospitals. The presence of ammonia as a result of protein decomposition can be toxic in the waters. The application of anoxic-oxic biofilter system is an attempt to be able to reduce ammonia levels in hospital wastewater. In the process of anoxic-oxic biofilter, contact occurs between the gravel media and microorganism to form biofilms which can accelerate the degradation of organic matter and the nitrification process. This study aims to obtain the best activated sludge source in reducing ammonia levels of wastewater applied to the anoxic-oxic biofilter system applied. This research was contucted in two stages in which the first stage of active mud nursery was carried out from three sources, namely WWTP Wangaya Hospital Denpasar, WWTP of PTN Hospital Udayana University and WWTP of Bangli Hospital for six days. At this stage a Mixed Liquor Volatile Suspended Solid (MLVSS) value is measured which shows the growth rate of biomass in activated sludge. The second stage is applivation of avtivated sludge and control to the anoxic-oxic biofilter system to reduce ammonia levels in hospital wastewater for five days of processing. This study use a randomized block design with four treatments and three replication. The results showed that the best activated sludge was obtained through nursery from WWTP of Wangaya Denpasar Hospital which was shown by the highest biomass growth (MLVSS Value) of 2433.3 mg/L and the highest reduction in ammonia reached a final level of 0.53 mg/L. The levels of effectiveness of the process of decreasing ammonia levels by 94.70% and has been able to pass the specified quality standard effectiveness percentage (90%) for five days of processing. The value of this effectiveness is the highest compared to the controls and other activated sludge treatment.

Abstract

Mokwam Area is one of the ecotourism objects in Warmare District, Manokwari Regency, West Papua Province. Whilst, it has a wide variety of endemic flora and fauna, ecotourism of Mokwam is also rich in herbs used by indigenous Mokwam known as Arfak tribe. The aim of this study were: 1) to identify the potential of ecotourism in Mokwam Area, 2) to better understanding constraints in ecotourism management supporting environmental preservation in Mokwam Area, and 3) to determine the ecotourism management strategies in favor of Mokwam environmental preservation. Data collection techniques of this research were observation, interview and documentation. The collected data was analysed by using qualitative descriptive and SWOT analysis. The SWOT is used to frame ecotourism management strategy by identifying internal and external factors. The results shows that the ecotourim potential of Mokwam area is a beautiful natural scenery, as well as biodiversity of flora and fauna. The potential attracted endemic faunas of Mokwam ecotourism is a variety of Birds of Paradise (Burung Cenderawasih) which are Cenderawasih Raja (Western Parotia), Cenderawasih Bela Rotan (Magnificent Bird of Paradise), Cenderawasih Ekor Panjang (Arfak Astrapia), Cenderawasih Buff-tailed sicklebill, Cenderawasih Long-tailed paradigala, Cenderawasih Black Sicklebill, as well as Namdurpolos Clever Bird (Vogelkop Bowerbird). Several considerable constraints in managing Mokwam ecotourism considering the environmental conservation is shifting cultivation method implementing by Arfak tribe. This method would potentially exterminate the forest as a habitat of the endemic flora and fauna if there is an increase in population, hot mix road access to Mokwam areas has still not been available and lack of cooperation between villages in Mokwam Area. The strategies based conservation concept in managing Mokwam ecotourism are promoting Mokwam potential ecotourim to the outside audiences; preserving the local wisdom of igya ser hanjob in order to protect the forests which are the habitat of endemic flora and fauna; improving road access to Mokwam Area; conducting comparative studies to similar tourism objects; establishing effective cooperation with other available tourism objects around Mokwam Area; empowering Arfak community about ecotourism management so that the community competitiveness towards other ecotourism areas could potentially be realised. Keywords: Ecotourism, biodiversity of flora and fauna, management strategy, local wisdom

Abstract

Effectiveness of Differences in the Planting Media Composition and Corm Size in Bali Local Banana (Musa paradisiaca var. Milk) Propagation Banana (Musa paradisiaca) is one of the important commodities in Indonesia. Based on BPS Prov data. Bali (2017), the number of productive banana plants in Bali has decreased enormously, from 13,140,965 clumps in 2016 to only 4,681,879 clumps alone in 2017. The need for banana supply is so high when balinese people celebrate Galungan and Kuningan Ceremony. Banana needs that occur cannot be met because the production in Bali is low, not filled with production because of difficulty in obtaining seedlings, for that it is necessary to do research on the composition of planting media and the right size of banana chopped corm to provide good banana seeds. The growth and development of good banana plant seeds cannot be separated from the use of good planting media and the use of quality seeds. This study aimed to find out the interaction of planting media composition and the size of chopped corm in local Balinese susu bananas. This research was conducted at the experimental garden paranet house of the Faculty of Agriculture, Udayana University, Jl. Pulau Moyo No. 15 X, Pedungan, South Denpasar, Denpasar City, Bali from April to July 2020. The design used in this study is RandomIzed Block Design (RBD) Factorial pattern with 2 treatment factors, the first factor was the composition of planting media consists of 4 levels of treatment namely M1 (mixed media of soil and compost (1:1/V:V) 100% + burn husk 0%), M2 (mixed media of soil and compost (1:1/V:V) 75% + burn husk 25 %), M3 (mixed soil and compost media (1:1/V:V) 50% + 50% burn husks), M4 (mixed soil and compost media (1:1/V:V) 25% + burn husks 75%), M5 (mixed soil and compost media (1:1/V:V) 0% + 100% burn husks). The second factor was the size of the weevil hemisphere, consisting of 3 levels of treatment, namely B1 (size of corm hemisphere 4 x 4 x 4 cm), B2 (6 x 6 x 6 cm) and B3 (8 x 8 x 8 cm). The results showed that M3 media (mixed soil and compost media (1:1/V:V) 50% + 50% burn husks) was the composition of the planting media was best, the M3 treatment produces leaf chlorophyll, plant height, number of leaves, diameter of stems, time of root appear and the time the bud appears. B3 (8 x 8 x 8 cm) was the best size of banana weevil, B3 treatment produces leaf chlorine, plant height, number of leaves, stem diameter, root time and the best leaf appear time. There was an interaction between the combination of planting media (M) and the size factor of weevil (B) to the growth of susu banana seedlings, which is indicated by the time the bud appears, the time the root appears, the diameter of the stem, the height of the plant and the number of leaves. The best value was obtained on the M3B3 combination.

Abstract

The Effectiveness Test of Indigenous Endomycorrhiza on Maize Plant Growth (Zea mays L.). Efforts to increase crop productivity were hampered due to various obstacles such as genetic, environmental, and biotic factors, in order that alternative technologies such as endomycorrhizal biological agents were required. This study was aimed to determine the effectiveness of indigenous endomycorrhiza for the growth of maize. The experiments were carried out in the laboratory and greenhouse. The field experiment was designed in a nested randomized block design. The first factor was genus of indigenous endomycorrhiza (M) consisting of 3 lavels i.e genus Glomus (G), genus Gigaspora (F) and the mixed genus (C), the second factor was the spore dose (D) consisting of 3 levels i.e. D1 = dose of 50 spores, D2 = 100 spores and D3 = 150 spores. The genus Glomus was able to increase the weight of fresh and dry oven total stalk, the number of leaves and the height of the plants and those significantly higher than that of the genus of Gigaspora and the mixed genus. Spore doses (50, 100 and 150 spores) of the genus Glomus and the genus Gigaspora and mixture gave no significant different results on all observed variables.
