Abstract

Kematian bibit akibat serangan penyakit layu bibit pala dirasakan sangat merugikan bagi para penangkar bibit. Jamur tanah telah dilaporkan dapat menekan perkembangan berbagai patogen tular tanah. Mikoriza adalah bentuk asosiasi jamur dengan tanaman yang memiliki kemampuan dalam meningkatkan ketahanan dan pertumbuhan tanaman. Tujuan penelitian adalah mengetahui jenis organisme penyebab penyakit layu pada bibit pala, mengetahui jenis-jenis jamur tanah yang berpotensi menekan perkembangan penyakit layu bibit pala dan mengetahui peranan mikoriza dalam meningkatkan ketahanan dan pertumbuhan tanaman. Penelitian dilakukan pada fase in vitro, fase perkecambahan dan pembibitan. Rancangan percobaan menggunakan Rancangan Acak Lengkap dengan tiga ulangan. Penyebab penyakit layu bibit pala adalah jamur Sclerotium rolfsii. Sebanyak 15 isolat jamur tanah diperoleh dari hasil eksplorasi. Hasil uji antagonisme secara in vitro menunjukkan bahwa terdapat 11 jamur tanah yang potensial menekan koloni jamur S. rolfsii  secara signifikan. Empat isolat jamur tanah, yaitu jamur Candida sp, Trichoderma viride, Trichoderma harzianum, dan Botrytis sp.1 konsisten secara nyata mampu menekan perkembangan S. rolfsii mulai dari pengujian in vitro, perkecambahan sampai pembibitan. Dengan penambahan mikoriza, maka Botrytis sp. 2 mampu menekan jamur S. rolfsii secara signifikan pada fase perkecambahan dan pembibitan. Pengujian pada fase perkecambahan, dilihat dari paramater pertumbuhan tanaman (kecuali panjang akar) seluruh perlakuan jamur tanah yang ditambahkan dengan mikoriza menujukkan beda nyata dengan tanaman kontrol. Pada fase pembibitan, dilihat dari parameter pertumbuhan tanaman (kecuali tinggi tanaman) seluruh perlakuan jamur dengan penambahan mikoriza juga menunjukkan beda nyata dengan kontrol, kecuali pada perlakuan jamur Paecilomyces sp.Kata kunci: Bibit pala, Jamur tanah, Mikoriza, Sclerotium rolfsii

Abstract

A laser rangefinder is a device that uses laser light to determine the distance of an object. The working principle of this laser rangefinder is that the laser beam that is emitted to the object will be reflected back to the rangefinder, and the required propagation time of laser beam will be calculated to get the distance value. In this study, a laser rangefinder system was designed to be used as monitoring of obstacle height between the line of sight of a microwave communication link using a quadcopter, which is used as a top-viewer picture taker. The quadcopter was used as a device to carry the laser rangefinder to measure the obstacle height between the location points of near-end and far-end. The obstacle height reading results were transmitted using a 5.8 GHz wireless transceiver to the monitoring location in real time. The data received were then processed to be displayed in the form of obstacle height graph as a function of the line of sight communication distance. The test results show that the implementation of laser rangefinder technology has an accuracy of more than 90%.Keywords: Line of Sight, Laser Rangefinder, Near-end and far-end, Quadcopter, Obstacle

Abstract

Demands for environmental protection, especially water resources and in development planning, have shown an increase in recent years. However, the reference for protection of water resources has always been based on the level of pollution or changes in water quality. This paper discusses groundwater balance as an approach for housing development planning. This approach assumes that all water needs for residents in a settlement area and their activities are met from groundwater, and the used groundwater must be replaced by water absorption into the soil in the area. For this reason, comprehensive rainwater management is needed. The potential for rainwater in residential areas requires greater management efforts; in addition to controlling the runoff that occurs, the use of clean water is also necessary. The results of runoff analysis for housing in downstream and upstream areas showed a potential for runoff of approximately 105-115% from before the construction of housing until after it has been inhabited. Rainwater management by using infiltration wells as large as 0.82 m3/m2 and water balance of 13.3% is less effective in downstream areas with shallow groundwater levels, but more effective in reservoirs and for seepage of runoff water using a catchment pool of 28.26% or 1.74 m3/m2.Meanwhile, for housing in upstream areas with a low permeability coefficient, the infiltration pond is less effective for water infiltration into the soil by 0.032 m3/m2 or 0.0054%, with a higher level of groundwater than in the downstream housing areas, which can use more effective infiltration wells. Overall, the management of rainwater for clean water and drinking water has sufficient discharge and the quality of the pH of rainwater from the roofs of houses is still feasible, between 6.6 and 7.8. The perspective of people on the use of rainwater as clean water and drinking water is quite positive, at approximately 59-61%.Keywords: Groundwater balance, rainwater harvest, sustainable settlement

Abstract

In its development, Mojokerto Regency experienced very rapid growth. The form of development control efforts to run optimally and sustainably is measuring the carrying capacity of the land. This study aims to evaluate the suitability between land capability and actual land use and allocation of land space patterns (RTRW) of Mojokerto Regency. Land capability is obtained by spatial analysis and overlay on several criteria for land boundary factors including soil texture, effective depth, drainage, land slope, and erosion rate. The description of actual use is obtained using landsat 8 OLI images at coverage time in May 2018. The results of the study show that the ability of land in Mojokerto Regency varies from class I land to class VIII land. The actual condition of land use in Mojokerto Regency 98% or an area of 95314.33 Ha was used according to the ability of the land, and 2% or an area of 2078.67 Ha the area used was inappropriate. Whereas in the allocation of land space patterns in Mojokerto Regency, 78.85% or an area of 76798.89 Ha was allocated accordingly, and 0.90% or an area of 875.29 Ha was allocated to exceed the capacity of the land, then 19.39% or an area of 18884.18 Ha is an allocation of land in a conditional manner so treatment is needed to optimize land use. This finding can be used to control land use and rearrangement materials for the allocation of land space in Mojokerto Regency.Keywords: Land capability, Actual land use, RTRW

Abstract

The objective of this study is to find out the availability of water, the distribution of spring locations, the amount of clean water needs, and the right strategy to maximize the management of clean water in Passo Village. To obtain the right management strategy, the SWOT method was applied in this study. Based on the results of SWOT analysis, it was found that the proposed alternative management strategy related to stable growth is directed at strengthening collaborative and participatory management by relying on the strength of costs or funds owned by the government and opportunity from society in management implementation. The three strategies consist of developing individual or family water management sites into society-based ones, improving water quality by maintaining vegetation around the springs, and developing sites for optimal water management by creating cooperation between society and the government in order to continue to meet the needs of society. The three strategies are expected to maximize society-based clean water management in Passo Village in Baguala Sub-District, City of Ambon.Keywords: Strategy, Water Management, SWOT
