Judul: Knowledge management system development for soybean’s pest at PUSTAKA (Indonesian Center for Agricultural Library and Technology Dissemination).
Abstrak: Knowledge management system is knowledge that learning how knowledge collected, stored, managed and disseminated. For an organization or enterprise, knowledge is an important resource. Those,well-organized knowledge established in order to provide value-added for enterprise or organization performance improvement. Through knowledge management, knowledgesfrom organization would be identified, resources of the organization would be known, existing knowledge could be re-used, accelerate the process of creating new knowledge from existing knowledge, and maintain the organization stability due to human resourceshifting. Besides, the existing organization knowledge would not disappear because it is not stored as a tacit knowledge, and everyone couldutilize the knowledge to create standard procedures even though the people who has the tacit knowlede are not in a place. One of the most important commodities that should be developed in Indonesia is soybean. This is because the soybean demand continues to increase along with the food industry development. Food products such as tofu, tempeh and soy sauce require large enough amount to supply its sustainability. Recently, Indonesia has not been able to maintain the soybeans demands, so imports must be done. One of the threats in an attempt to achieve self-sufficiency soybeans are a nuisance pest. There are 111 species of soybean pests that been recorded. Therefore, have a comprehensive documentation knowledge about soybean pest control technology-that is easily accessible-is a major issue in order to reduce losses due to pests. This research methodology adapted from life cyle knowledge management system that consists of several stages.The stages are knowledge management system evaluation, teamforming, knowledgecapturing, blueprintsdesigning, systemdeveloping, andsystem applications testing process. Result of the soybean pest knowledge management system development could be used as a means to capture, collect, store, preserve and disseminate knowledge. Hopefully with this system, farmers could obtain more information about soybean pests that applied in the soybean cultivation. Furthermore, the system could assist trainers and experts to introduce the soybean pests and their control technology to the farmers, so that farmers could reduce the losses when planting soybeans.

Abstrak: Soybean is one of the commodities that is instrumental in food needs. However, Indonesia has not been able to fulfill its own need of soybean. Some problems faced by soybean farmers include the selection of good varieties, disruption of pest and diseases. Because of the limitations of experts to disseminate information about soybeans, it is necessary to build a system that can manage and store information so that the information can be easily accessed. To this end, we utilize the system development life cycle to develop information of soybean pests and diseases into an information system kedelai.ipb.ac.id. This method consists of five stages, namely: planning, analysis, design, implementation, and support. A Drupal core is used in the implementation of the information system in this research. The research result consists of two parts namely the information of pest and disease. The information of pest consists of the pest characteristics, indications, and controls. The disease information consists of disease characteristics, indications, and controls.

Judul: Monotonicity Properties of Trapezoid Sum Sequence on Class of Nonconvex and Nonconcave Function
Abstrak: Bernhard Riemann mendefinisikan integral tentu sebagai luas daerah di bawah kurva dari suatu fungsi real taknegatif pada sebuah interval yang tertutup dan terbatas. Beberapa alternatif yang dapat digunakan untuk menghampiri luas tersebut adalah Darboux sums melalui penjumlahan beberapa luas persegi panjang dan trapezoid sum melalui penjumlahan luas trapesium. Trapezoid sum lebih baik dalam menghampiri nilai integral untuk fungsi-fungsi yang well-behaved daripada Darboux sums. Untuk fungsi f yang bernilai real dan kontinu pada interval [a,b], f terintegral Riemann jika dan hanya jika f terintegral Darboux. Pada tesis ini ditunjukkan bahwa f terintegral Riemann jika dan hanya jika f terintegral secara trapesium. Misalkan f adalah suatu fungsi bernilai real yang kontinu pada interval [a,b]. Untuk setiap partisi P_n yang membagi [a,b] menjadi n subinterval dengan jarak yang sama, dibentuk trapezoid sum T_n (f) yang merupakan jumlah luas n trapesium sebagai pendekatan dari nilai integral f pada [a,b]. Jika f adalah fungsi konveks maka barisan trapezoid sum {T_n (f)} bersifat monoton turun dan akan bersifat monoton naik jika f fungsi konkaf. Fokus tesis ini adalah sifat kemonotonan barisan {T_n (f)} untuk fungsi f yang nonkonkaf dan fungsi f yang nonkonveks. Pada tesis ini dibuktikan sifat monoton turun dari {T_n (f)} secara generik tidak terjadi pada kelas fungsi nonkonkaf f, serta secara generik, barisan itu juga tidak monoton naik pada kelas fungsi nonkonveks. Meskipun demikian, sifat generik mengakibatkan bahwa untuk sebarang fungsi f baik di kelas fungsi nonkonkaf maupun nonkonveks, terdapat fungsi g yang menghampiri f sedemikian sehingga ekor barisan {T_n (g)} bersifat monoton. Ditunjukkan pula bahwa himpunan fungsi naik nonkonkaf dengan {T_n (f)} yang tidak monoton turun dense terhadap kelas fungsi naik nonkonkaf f. Hal tersebut juga ditunjukkan untuk himpunan fungsi turun nonkonkaf terhadap kelas fungsi turun nonkonkaf. Lalu, dibuktikan bahwa himpunan fungsi naik nonkonveks dan himpunan fungsi turun nonkonveks dengan {T_n (f)} yang tidak monoton naik, berturut-turut dense terhadap kelas fungsi naik nonkonveks dan turun nonkonveks. Himpunan-himpunan yang dense tersebut mengartikan bahwa setiap fungsi f pada kelas-kelas tersebut, dapat dihampiri oleh suatu fungsi g yang bersesuaian dengan kelas-kelas tersebut sedemikiam sehingga barisan {T_n (g)} tidak monoton., Bernhard Riemann defined definite integral as an area under the curve of a real nonnegative function on a closed bounded interval. The alternatives that can be used to estimate the area are Darboux sum which is sum of rectangular areas and trapezoid sum which is sum of trapezium areas. Trapezoid sum is better than Darboux sum as approximations toward the integral of well-behaved functions. Let f be a real valued continuous function on interval [a,b], f is Riemann integrable if and only if it is Darboux integrable. In this master’s thesis, it showed that f is Riemann integrable if and only if it is trapezium integrable. Let f be a real valued continuous function on interval [a,b]. For each partition P_n that divides the interval [a,b] into n equal length subintervals, defined trapezoid sum T_n (f) which is the total of n trapezium areas as an approach of integral value f on [a,b]. If f is a convex function then the trapezoid sum sequence {T_n (f)} is decreasing
