Abstract

Every businessmen would want to expand his business to be bigger, to do that it needs a lot of funds. The bank can provide kredit usaha rakyat with some of reqruitment collateral that has be obeyed by bussinesmen, one of them is to provide guarantee, the problem is not all the bussinesment can provide the guarantor. Therefore bussnismen need guarantor institution help in order to fulfill the requiment. As the Demand from banks for credit guarantee to increase every month, it ensures that the guarantor institution must increase its budget to guarantee the kredit usaha rakyat. Therefore a system that is able to predict the amount of guarantee value will be needed in order to meet the demand of the bank. In this research the method used to predict is Fuzzy Time Series which will be optimized using Genetic Algorithm. A chromosome is used to represent the interval of a membership function. The reproduction method is one-cut-point crossover and uniform mutation. And do the selection process by using elitism selection. The optimal results obtained with the length of chromosome as much as 100, the population size of 350, cr and mr of 0.3 and 0.6 and the number of generations as much as 1000. The error and fitness value generated by 0.00901% for MAPE and 110.95098192994908 for fitness value.

Abstract

Intensitas hujan yang tinggi akan menyebabkan limpasan permukaan yang besar dan dapat berdampak negatif.  Kurva IDF mempermudah perhitungan debit banjir rencana. Tujuan penelitian ini adalah menentukan metode empiris intensitas hujan dan IDF yang cocok untuk lokasi penelitian. Metode yang digunakan adalah Talbot, Mononobe, Hasper Der Weduwen, dan Van Breen.  Hasil perhitungan menunjukkan bahwa Metode Talbot yang paling sesuai digunakan di lokasi penelitian.  Metode Talbot memiliki nilai Deviasi Rata-rata 1.49; Kesalahan Relatif (Kr) rata-rata sebesar 8.64% dan Koefisien Nash Sutcliffe (ENS) rata-rata sebesar 0.98.  Kemudian dilakukan validasi metode terpilih menggunakan kala ulang 2 tahun dan 5 tahun dengan membandingkan intensitas hujan metode empiris dan intensitas hujan pengamatan dengan hasil nilai Deviasi Rata-rata sebesar 2.22; nilai Kesalahan Relatif (Kr) rata-rata sebesar 15.11%, dan Koefisien Nash Sutcliffe (ENS) rata-rata sebesar 0.93.

Abstract

Informasi evaporasi waduk penting untuk mengetahui signifikansi kehilangan air akibat evaporasi yang mencapai 90-95% dari total kehilangan air di waduk. Permasalahan yang sering dihadapi pada data evaporasi adalah minimnya ketersediaan data. Untuk mengatasi permasalahan tersebut, satelit GLDAS-2.1 dan CFS-V2 memiliki kemampuan dalam mengestimasi evaporasi di permukaan. Satelit tersebut memiliki resolusi spasial dan temporal yang tinggi, jangkauan wilayahnya luas, data near realtime dan terekam secara kontinyu, akses cepat dan ekonomis. Namun, suatu data satelit dapat dimanfaatkan apabila memiliki koherensi yang kuat dengan data observasi. Tujuan penelitian ini adalah untuk melakukan evaluasi kesesuaian data evaporasi satelit GLDAS-2.1 dan CFS-V2 terhadap data evaporasi pengamatan dan merekomendasikan satelit mana yang tepat dalam mengestimasi evaporasi sehingga dapat dimanfaatkan sebagai alternatif ketersediaan data evaporasi di Waduk Wonorejo. Evaluasi yang dilakukan pada studi ini menggunakan analisa statistika di Stasiun Geofisika Wonorejo. Hasil kalibrasi data pada satelit GLDAS-2.1 dan CFS-V2 menghasilkan faktor koreksi dengan bentuk persamaan regresi polinomial. Pada tahap validasi terkoreksi nilai RMSE, NSE, R dan KR menunjukkan hasil yang lebih baik yang awalnya sebesar 21% sebelum terkoreksi naik menjadi 79% setelah terkoreksi. Satelit GLDAS-2.1 menjadi satelit yang direkomendasikan karena menghasilkan nilai NSE dan R2 yang jauh lebih baik dengan persentase sebesar 100% jika dibandingkan CFS-V2.Reservoir evaporation information is important to determine the significance of water loss due to evaporation which reaches 90-95% of the total water loss in the reservoir. The problem that is often faced with evaporation data is the lack of data availability. To overcome these problems, the GLDAS-2.1 and CFS-V2 satellites have the ability to estimate evaporation on the surface. The satellite has a high spatial and temporal resolution, wide-area coverage, near real-time data and recorded continuously, fast accessibility, and economical. However, satellite data can be used if it has a strong coherence with the observation data. The purpose of this research is to evaluate the suitability of the evaporation data from the GLDAS-2.1 and CFS-V2 satellites to the observational evaporation data and to recommend which satellite is appropriate for estimating evaporation so that it can be used as an alternative to the availability of evaporation data in the Wonorejo Reservoir. The evaluation carried out in this study uses statistical analysis at the Wonorejo Geophysical Station. Results of data calibration on the GLDAS-2.1 and CFS-V2 satellite produce a correction factor in the form of a polynomial regression equation. At the validation stage, the RMSE, NSE, R, and KR values showed better results that were initially 21% before being corrected, increasing to 79%. GLDAS-2.1 is still being recommended compares with CFS-V2, because it produces much better NSE and R2 values with precentage of 100%.

Abstract

This study specifically tries to see the effect of compensation on the employee performance of MSMEs with motivation as a mediating variable at the Sanan Tempe Chips Industry Center. The method in this study is a type of quantitative research using Structural Equation Modeling (SEM) analysis with the WarpPLS approach. This study also uses the Sobel Test to analyze the significant value of the indirect relationship between compensation and employee performance mediated by motivation. In-depth interviews using questionnaires and direct observation were conducted to obtain primary research data. Meanwhile, secondary data was obtained through literature studies from various sources related to the research. A total of 60 respondents were selected as samples in this study using a simple random sampling technique. The results showed that the motivation variable had a significant effect as a mediating variable on the relationship between compensation and employee performance. This means that compensation has an indirect effect on employee performance through motivation.

Abstract

Pengembangan Museum Desa Pertanian di Desa Karangpatihan, Kabupaten Ponorogo, bertujuan untuk meningkatkan potensi pariwisata edukatif berbasis pertanian. Desa Karangpatihan, yang dikenal dengan keunikan budaya dan tantangan sosialnya, menghadapi berbagai permasalahan, termasuk tingkat kemiskinan yang tinggi dan keterbatasan ekonomi. Museum ini diharapkan dapat mempromosikan warisan pertanian tradisional sekaligus mengedukasi pengunjung tentang praktik pertanian berkelanjutan, serta memberdayakan masyarakat desa. Pengembangan museum dilakukan dengan metode partisipatif, melibatkan pemerintah desa, masyarakat lokal, dan akademisi melalui survei, wawancara, dan diskusi kelompok terarah (FGD). Desain museum mencakup area pameran alat pertanian tradisional, ruang edukasi, dan pendopo serbaguna, yang semuanya diintegrasikan dengan peta potensi unggulan desa. Luaran dari kegiatan ini adalah desain museum yang komprehensif serta rencana strategis untuk pengelolaan museum sebagai pusat edukasi dan destinasi wisata. Dengan adanya museum ini, diharapkan tercipta peluang ekonomi baru bagi masyarakat desa dan promosi pariwisata yang berkelanjutan di Desa Karangpatihan
