Disease intensity of moler and yield losses of Shallot cv. Bima caused by Fusarium oxysporum f.sp. cepae in Brebes Central Java

Brebes Central Java is one of the central production of shallot in Indonesia. In the latest years, shallot farmers in Brebes face a new problem in their production, that is the increasing attack of Fusarium oxyspsorum f.sp. cepae (FOCe) which causes Moler disease (MD). Based on a previous survey of respondents, the most common variety planted by the farmer in Brebes was cv Bima that had disease intensity up to 60% with yield losses over 40%. The field data related to disease intensity and yield losses caused by the pathogen are still very limited. This paper reports the occurrence of disease intensity of MD and its correlation to yield losses based on the primary data that was collected through a direct assessment on the field of shallot plantings in Brebes. The results show that the disease intensity of MD varies from 0 to 75% which significantly affects yield losses. Yield losses of same shallot plantings are over 50%.

Performance of Sugarcane Farming Ratoon System in East Java Province

The fulfillment of national sugar consumption needs cannot be achieved by domestic production. Increase sugar cane production to fulfill the availability of sugar in Indonesia, one of which in the central production area of East Java is still constrained by many sugarcane farmers who are doing ratoon system more than three times, so the productivity is low. This study aimed to analyze the performance sugarcane farming ratoon system in East Java by looking at technical efficiency and scale efficiency using the non-parametric approach of Data Envelopment Analysis (DEA). Sampling in this study used multistage random sampling in Kediri, Malang, and Mojokerto Districts. The average total technical efficiency (TE CRS) of farmers with 1-3 ratoons is 0.754, the pure technical efficiency (TE VRS) is 0.817, and the scale efficiency is 0.926. The average TE CRS of farmers with 4-6 ratoons is 0.693, TE VRS is 0.814, and the scale efficiency is 0.860. For farmers who do more than seven ratoons, an average TE CRS is 0.609, TE VRS is 0.693, and scale efficiency is 0.894. The majority of sugarcane farmers at the research site have not been on an optimal business scale, namely in IRS conditions.

AC-DC Microgrid Optimal Power Flow

Electricity market deregulation has opened the door for novel electricity production schemes within the existing central production paradigm that dominates the electricity power industry. The Microgrid concept allows generation and load located in close vicinity to be organized so that the local load is served as far as possible with local generation. The Microgrid examined in this thesis consists of both AC and DC network components connected using power converters. The varied Microgrid power sources (microturbine generators, PV, battery, power imports from the grid etc.) are scheduled over 24 hours to satisfy load demand at minimum cost and maximum reliability. Towards this end, a dual objective problem is formulated using Fuzzy sets and the final problem takes the form of a Mixed-Integer Nonlinear optimization problem. The interplay between the disparate objectives of minimum cost and maximum reliability and the battery is then examined.

Methods of Data Popularity Evaluation in the ATLAS Experiment at the LHC

The ATLAS Experiment at the LHC generates petabytes of data that is distributed among 160 computing sites all over the world and is processed continuously by various central production and user analysis tasks. The popularity of data is typically measured as the number of accesses and plays an important role in resolving data management issues: deleting, replicating, moving between tapes, disks and caches. These data management procedures were still carried out in a semi-manual mode and now we have focused our efforts on automating it, making use of the historical knowledge about existing data management strategies. In this study we describe sources of information about data popularity and demonstrate their consistency. Based on the calculated popularity measurements, various distributions were obtained. Auxiliary information about replication and task processing allowed us to evaluate the correspondence between the number of tasks with popular data executed per site and the number of replicas per site. We also examine the popularity of user analysis data that is much less predictable than in the central production and requires more indicators than just the number of accesses.

PENENTUAN POLA PENGEMBANGAN AGROINDUSTRI JAMBU METE

ABSTRAK<br />Sebagai produsen mete, agroindustri mete di Indonesia masih belum<br />berkembang. Sekitar 36% produksi masih diekspor dalam bentuk<br />gelondong. Pengembangan agroindustri mete yang mengandalkan industri<br />besar tidak berjalan baik. Untuk itu perlu dicari pola yang tepat untuk<br />pengembangan agroindustri mete. Penelitian ini menggunakan pendekatan<br />system dengan menerapkan metode AHP (Analytic Hierarchy Process)<br />untuk menentukan skenario terbaik pengembangan industri mete nasional<br />yang kuat. Akuisisi pendapat pakar dilakukan dengan wawancara intensif<br />dan melalui FGD terhadap tujuh pakar di Bogor pada bulan Februari 2007.<br />Faktor penentu keberhasilan pengembangan agroindustri mete dengan<br />tingkat kepentingan relatif tertinggi adalah ketersediaan bahan baku.<br />Faktor ini sangat ditentukan oleh kinerja aktor petani dalam usahataninya,<br />sehingga aktor petani memiliki tingkat kepentingan relatif tertinggi di<br />antara ketiga aktor penentu. Kinerja usahatani ditentukan oleh<br />terpenuhinya obyektif dari aktor petani terutama obyektif pendapatan<br />usahatani yang baik. Dari ketiga skenario pola pengembangan industri<br />mete, pola industri dengan basis industri kecil skala rumah tangga untuk<br />pengacipan yang ditunjang industri pengolahan kulit mete ditingkat<br />kabupaten sentra produksi mete dipilih sebagai pola terbaik karena dapat<br />memenuhi seluruh obyektif petani dengan baik. Kebijakan yang perlu<br />diambil dalam membangun industri mete dengan pola terpilih adalah<br />dengan membentuk klaster industri mete di kabupaten sentra produksi<br />mete, meningkatkan pendapatan petani melalui pengenalan budidaya<br />anjuran, tanaman sela dan diversifikasi hasil, serta mendorong per-<br />dagangan kacang mete ke negara-negara terdekat pengimpor kacang mete<br />seperti Australia, Jepang, Uni Emirat Arab dan Arab Saudi.<br />Kata kunci : Jambu mete, Anacardium occidentale, AHP, agroindustri,<br />klaster<br />ABSTRACT<br />Assortment of patrons of cashew agroindustry<br />development<br />As a cashew producer, Indonesia’s cashew agroindustry has not<br />been developed yet. Around 36% of cashew production is exported<br />without being processed. For that reason, a proper patron of cashew<br />agroindustry development should be found. This research used system<br />approach. AHP method had been applied to judge the best scenario of the<br />patron of cashew agroindustry development. Acquisition of expert<br />judgement had been done by intensive interview and FGD to seven expert<br />in Bogor in February 2007. The analysis showed that raw material of<br />cashew supply is the most important determinant factor in developing<br />cashew agroindustry. Performance of this factor is depend on the<br />performance of farmers in managing their farming. This condition put<br />farmers as the most important actor in developing cashew agroindustry.<br />The performance of the farmers depends on how the scenario can fulfill<br />the objectives of the farmers. From three scenarios judged, cashew<br />agroindustry based on home industry in cashew central production<br />regencies is the best scenario that can fulfil all objectives of the farmer.<br />Policies should be taken in developing cashew agroindustry using this<br />scenario are: building clusters of the cashew industry in cashew central<br />production regencies, Increasing farmers income from their farming by<br />introducing good farming systems, intercropping, product diversification<br />of cashew and increasing cashew nut export to importer countries such as<br />Australia, Japan, Uni Emirate Arab and Saudi Arabia.<br />Key words: Cashew, Anacardium occidentale, AHP, agroindustry, cluster
