Abstract

The objective of the study is to determine the potence of natural agent, a mmushroom of Gliocladium sp. and bacterium Peudomonas fluorencens in resisting against the withering disease (Fusarium Oxysporum f.sp. Cubense) and their effect to the growth of the in-vitrocultured banana plant (Musa paradisiaca L). Thiswas conducted in the experimental farm of Agriculture Faculty, University of Muhammadiyah Purwokerto, in the period of June to December 2013.This research is a single experiment using Randomized Completely Block Design. The treatment was the administration of Gliocladium sp. In three different doses of 10 g/polybag (G1),20 g/ polybag (G2), 30 g/ polybag (G3), and the giving of Pseudomonas fluorencens inthree different dosage of10 ml/l water/ polybag (PF1),20 ml/l water/polybag (PF2) and 30 ml/l water/polybag(PF3) and one control group of no treatment (K0).Based on the result of data analysis, it is proved that the treatment of natural agents of Gliocladiumsp and Pseudomonas fluorencenshas induced the plants resistance against the withering disease of FusariumOxysporumf.sp. Cubense in the banana, as it is indicated bythe increase of phenol compounds, i.e. glychoseda, saponin, and thanin. However, the treatment has no significant effect on the plant growth either on their leaves or their stalk diameter.

Abstract

Protected forests have drawn international attention.  This research aims to determine scenarios of land-use change in Protected Forest of Wosi Rendani (PFWR).  The study was conducted using land evaluation approach to land unit, determination and alternative land use change, based on the potential and the level of threat for PFWR.  The results showed that PFWR should remain as a protected forest although the total score of forest modeling was 130. This forest serves to protect soil, water, and danger from floods and landslides. This region has springs, caves, and waterfalls, which can be further developed into eco-tourism and environmental services. As a city forest, PFWR makes Manokwari's weather cooler, enhances the quality of air, reduces environmental pollution, and adds catchment areas. As a community forest, PFWR has forest plants, agricultural crops and fruits, in which people are only allowed to take flowers, fruits, and seeds they have planted. As a buffer zone, PFWR serves as a buffer to reduce population pressures on the forest area or village surrounding the area with high interaction by integrating conservation and economic interests of the surrounding community. As cultivation and settlement, PFWR has three settlements, namely Soribo, Kentestar, and Ipingoisi, 4 settlements outside PFWR namely Tanah Merah Indah, Ajoi, Buton, Mako Brimob, as well as plots of land owned by developers such as Bank Arfindo, Lumintu, Irman Jaya, and Suntari. The final scenario of the land use change in PFWR depends on the policy of local and central government.

Abstract

Tanaman nilam (Pogostemon cablin Benth) merupakan salah satu tanaman penghasil minyak atsiri yang penting dan merupakan penghasil devisa negara yang cukup tinggi.  Minyak nilam mempunyai prospek yang cerah karena permintaan untuk bahan baku industri parfum, kosmetik, sabun, dan kebutuhan lainnya terus meningkat.  Desa Limpakuwus merupakan salah satu desa di kaki Gunung Slamet di wilayah Kab. Banyumas, Prov. Jawa Tengah dengan luas pertanaman nilam ±340 ha.  Petani nilam menjual dalam bentuk  daun segar, daun kering atau dalam bentuk minyak nilam. Kendala yang dihadapi adalah produksi yang masih rendah karena teknik budidaya nilam yang kurang memadai dan gangguan penyakit budog dan layu bakteri nilam.  Selain itu peralatan penyulingan minyak nilam yang sudah usang menjadikan kuantitas dan kualitas hasil minyak nilam rendah. Metode yang dipakai dari kegiatan Ipteks bagi Masyarakat (IbM) yaitu : 1). Penyuluhan teknik budidaya nilam dan pengendalian penyakit budog dan layu bakteri   2). Demontrasi plot dengan menanam nilam di lahan dengan Corynebacterium dan 3). Pengadaan (pemberian bantuan) alat penyulingan minyak nilam.  Tujuan  dilaksanakan IbM ini : masyarakat/petani nilam di Desa Limpakuwus dapat mandiri secara ekonomi, lebih sejahtera dan termotivasi untuk menjadi wirausahawan minyak nilam.  Target khusus  dari kegiatan IbM yaitu petani mempunyai keterampilan yang lebih baik dalam teknik budidaya nilam dan penanggulangan penyakit budog dan layu bakteri pada tanaman nilam sehingga kuantitas dan kualitas hasil nilam meningkat.  Dengan pengadaan alat penyulingan minyak nilam yang baru, petani/masyarakat dapat meningkatkan nilai jual berupa minyak nilam yang lebih berkualitas dan akan mendorong munculnya wirausahawan baru penyuling minyak nilam.  Kesimpulan : 1). Kegiatan IbM ini cukup efektif bagi petani khususnya di Desa Limpakuwus karena petani dapat secara langsung berdiskusi aktif dan melihat hasil demonstrasi budidaya nilam dan penanggulangan penyakit layu dan budog dengan baik sehingga keterampilan dan wawasannya meningkat. 2) Kegiatan demonstrasi penanaman nilam dapat dihasilkan 693.75 g nilam segar/tanaman (24.98 ton/ha). 3). Pemberian alat penyulingan nilam baru dengan kualitas terbuat dari besi stainless dapat meningkatkan kualitas minyak nilam. 4). Aplikasi Corynebacterium dapat menurunkan intensitas penyakit budog pada tanaman nilam rata-rata dari 7.65% menjadi 6.23%.  Selama penanaman nilam tidak dijumpai penyakit layu.Kata Kunci: Nilam, Budog, Layu Bakteri, Alat Penyulingan

Abstract

Siam weed growing in any locations can be used for developing organic agriculture in Indonesia. The research was to find the quantitative and qualitative potential of siam weed as compost material for organic shallot cultivation. This study was descriptive-quantitative research using survey method done in four regencies in Yogyakarta Special Province and laboratory analysis. Purposive random sampling was used in survey method to determine the samples by applying random sampling and nested design. Laboratory analysis was to know nutrient content of siam weed. Shallot was planted using siam weed compost of 10 and 20 ton ha-1, inorganic fertilizer of 500 kg NPK Mutiara 16-16-16 ha-1 and the control. Siam weed was potential for developing organic shallot in Indonesia. Siam weed produced fresh biomass of 80 ton ha-1 with the population density of 24-37 individual m-2 and spread over almost all locations in Yogyakarta Special Province. Siam weed also contained higher nutrients of 2.56% N, 0.38% P, and 2.41% K with C/N ratio of 19.52 under the critical point of 30 so that easy to mineralized. The use of siam weed compost stimulated leaf number on shallot at 7 weeks after planting compared to the use of inorganic fertilizer and the control, but gave no significant yield of 19.71, 15.56, and 18.92 ton ha-1 of bulb, respectively.Keywords: organic fertilizer, development, nutrient

Abstract

A distinctive classification should be applied to government budget, particularly between budget allocation for consumption and for investment. This is important for policy makers so that they will be able to forecast investment and consumption effects on economic growth and inflation. In Indonesian budget system, unclear criteria to distinguish routine and development budget also creates many problematic situations in managing public finance. This article offers some alternatives to solve the problem. One simple solution is to reformulate what is the so-called projects. Projects are an activity or a group of activities which has certain goals and objectives, attains to result new physical or non-physical assets in the form of goods, services or capability improvements. Those activities are managed whithin certain span of time and amount of fund. Instead of consumptions, projects are primarily investments. If this alternative is implemented consistently in the budget allocation systems, it may decrease the figure of government saving and number of Project List Proposal (Daftar Isian Proyek - DIP), which may not be favorable for implementors who have vested interest. By doing so, however, overlapped activities which are funded by routine and development budget can be avoided substantially. Government accounting system would be more efficient because every projects should be resulted in investment. A more radical approach is to invalidate the distinction between routine and development (non-routine) budget allocation by all means. Productivity and accountability would be the main criteria for all forms of the government fund allocation. There should be a fundamental change in the government budget cycle. Government saving should be formulated into: the subtraction between domestic revenue and additional finance (belanja penunjang), and T-account system in the government budget (APBN) should be substantially modified. Finally, all of these remedies depend on effort to distinguish clearly between routine and project criteria through a transparent definition and vision of those who manage the budget allocation system.

Abstract

Biological control is an important component of integrated pest management, including integrated pest management on weed. One of the important biological control agents is plantpathogenic fungi. The purpose of this research is to identify potential fungi to be developed as an agent of biological control on alang-alang (Imperata cylindrica L). A survey was conducted in highland and lowland areas which were seriously infested by alang-alang to know the disease intensity and its distribution. Sample of diseased leaves were taken for identification and pathogenecity testing. Four fungal diseases - leaf blight, rust and two kinds of leaf spot that are caused by Phoma sp, Puccinia rufipes Diet and two unidentified pathogens - were found. By inoculation trials it was proven that Phoma sp. is pathogenic to alang-alang. Considering that there are potential pathogenic fungi causing several diseases on alang-alang, it is possible to develop a method of controlling the grass by using pathogenic fungi.
