Abstract

ABSTRACT The Faculty of Engineering, Universitas Sebelas Maret Surakarta (UNS) seeks to improve services in the cleaning sector, with the aim that students feel comfortable while on campus. Improving cleaning services can be done by applying the assessment and measurement of the performance of the cleaning staff. Performance appraisal is carried out based on performance reports collected by the cleaning staff. In compiling reports on the performance of the cleaning staff, they still use the manual method. The manual method used is to record all work activities into a book, then recap the notes to the Microsoft Excel application. The current method is considered less effective and efficient because it takes a relatively long time to compile a report. The cleaning staff is sometimes late in submitting performance reports, so the assessment cannot be done on time. Based on these problems, a website-based employee performance reporting system is designed, so that it can help provide convenience and support cleaning staff in improving their performance. The method used to design information systems is the System Development Life Cycle (SDLC) with the Waterfall model. The employee performance reporting system is made using the PHP programming language and MySQL database. With this system, the cleaning staff is more efficient and effective in presenting performance reports so that they can be assessed on time. Keywords: Information System, Performance, PHP, MySQL, CodeIgniter

Abstract

This study aimed to examine the influences of the Indian Ocean Dipole (IOD) on rainfall in three districts in South Aceh. The analysis was undertaken using Dipole Mode Index (DMI) data and five years of rainfall (2016 to 2020) in West Labuhan Haji, Tapak Tuan, and Bakongan areas. This research employed a correlation analysis and the Principal Component Analysis, followed by Cluster Analysis to investigate the relationship between IOD and rainfall at the study location. The negative IOD occurred in 2016, and the positive IOD occurred in 2017, 2018, 2019, and 2020. The strongest positive DMI was in October 2019 (1.123˚C), while the strongest negative DMI was in July 2016 (0.661˚C). Generally, the sub-districts of West Labuhan Haji, Tapak Tuan, and Bakongan always have high rainfall. The highest rainfall in West Labuhan Haji was recorded in January 2017 (1014 mm/month), in Tapak Tuan in November 2017 (1073 mm/month), and in Bakongan in July 2020 (605 mm/month). The correlation between DMI and rainfall in the three locations shows different findings. Although it was very small, the IOD affected the rainfall in West Labuhan Haji, Tapak Tuan, and Bakongan. In West Labuhan Haji, the highest correlation was in lag 1 (0.188); in Tapak Tuan, the highest correlation was in lag 2 (0.156), while in Bakongan, the highest correlation was in lag 2 (-0.191). The correlations in these three locations are considered weak. Thus, the IOD is not the main factor affecting the rainfall in West Labuhan Haji, Tapak Tuan, and Bakongan. As South Aceh is located in windward, the orographic effect may influence high rainfall in this region.Keywords:DMIRainfallPrincipal component AnalysisWest Labuhan HajiTapak TuanBakongan

Abstract

Pepper production Lampung grow slower and lower caused by among others 25,34% of plants on unyield condition. It also impacts on pepper export performance. This research aims to analize the factors influencing the pepper production and income of the farmers. Production centre in North Lampung is represented by Abung Tinggi subdistrict as research location. It was conducted on May until August 2012. Thirty pepper farmers were purposively choosen as respondents. They are members in farmer institution group at Pulau Panggung and Sukamarga villages. Analysis was done through Cobb Douglas production function and multiple regression. The result of research performed shows that the pepper production is influenced by seed, fertilizer, labor¸ and dummy variable of institution performance. In the other hand, farmers’ income has also been influenced significantly by pepper production, member of labors family, and dummy variable of institution performance.Key words: production, income, farmers institution

Abstract

Development issues in the fisheries sub-sector is one of fishery products easily damaged and nonperishable, its implications need special handling and good processing of fish.To inhibit the growth of microorganisms that cause decaying in fish can be done two ways, namely the preservation of traditional and modern fishing. One of traditionally  fish preservation  is done  by salting or often called stockfish. This study aims to analyze the production process and the factors that influence the production of salted anchovies fish agro- industry in labuhan Maringgai subdistrict East Lampung regency. The number of samples in this study were 30 respondents. The study was conducted from June to November 2012. Data was analyzed by descriptive qualitative and quantitatively by using multiple regression statistical analysis approach of cobb-douglas production function. The results of this research showed the production of salted anchovies were done traditionally, with the production of agro-processing stages include salted anchovies; sorting of raw materials, washing, boiling, draining, drying, sorting, packaging, and marketing.  Resulted average production anchovies agro- industry reached 593.33 kg per period, the annual production capacity reaches 170 times. The factors that significantly affect the production of salted fish agro- industry is raw fish , sinks, deep soaking tubs, and a dummy use of ice, while the factors that did not significantly affect the production of salted anchovies agro- industry is salt, labor, and drying place.Elasticity value of  Agro-industry productionof  salted anchovies fish preservation in the research area is 1.006 which means Elasticity Production (EP> 1), indicating that the scale of agro economy salted anchovy fish preservation in condition increasing return to scale, the addition of the factors of production will lead to increase a greater production  . Keywords: anchovies, production, processing, preservation, and agro-industry.
