Abstract

Beberapa model alternatif perancangan tata-letak fasilitas pabrik pada unit pengolahan kopi perlu dilakukan dalam peningkatan efisiensi dan produktivitas pabrik kopi di Sidomulyo. Metode deskriptif digunakan dengan analisis tata-letak dan perbandingan berpasangan (software POM for Window Layout analysis and Pairwise Comparisson type) untuk menentukan biaya transportasi aliran bahan, waktu tempuh aliran bahan, dan waktu operasi pengolahan. Sebagai perbandingan, tata-letak awal digunakan sebagai parameter. Hasil penelitian menunjukkan bahwa efisiensi dan produktivitas tertinggialiran bahan  tercapai pada biaya transportasi terendah (Rp 710,66) dengan waktu tempuh aliran bahan terpendek (71,02 detik), dan waktu operasi pengolahan bahan tersingkat (26,14 jam). Kata kunci: kopi, biaya transportasi, POM for Windows

Abstract

AbstractThe research shows the application of Soil Stability Index Mapping (SINMAP) to predict the potential of landslide hazard. The study was conducted at Rawatamtu sub-Watershed, located at Jember Regency.Input data for this study are: (1) digital elevation model (DEM), (2) physical preperties of soil, (3) rainfall data, and (4) other GIS layers collected from the study area. The DEM was obtained from ASTER GDEM2.SINMAP calculate the soil stability index based on combination effect of: slope stability, soil properties, land use and rainfall intensity. Then, interaction of those four factors are integrated on SINMAP and are classified as soil stability index. About 50 locations were surveyed by GPS and optical camera to interpret the map qualitatively. Result show the stable zone (index value > 1.5) occupied about 64.7 % of the watershed area. Area that classified in the upper and bottom limit of landslide (i.e. potentially subject to landslide hazard) are located at both mountain areas (Mount Argopuro and Raung) of the sub-watershed.Keywords: soil-stability-index, SINMAP, Landslide, RawatamtuAbstrakPenelitian ini bertujuan untuk membuat peta stabilitas tanah dan menginterpretasikan indeks stabilitas tanah tersebut untuk prediksi longsor dengan menggunakan SINMAP (Soil Stability Index Mapping).Penelitian dilakukan di Sub-Das Rawatamtu (Kab. Jember). Input data terdiri dari: (1) ASTER GDEM2 (ketelitian pixel ± 30m), (2) data karakteristik fisik tanah, (3) karakteristik fisik hujan, dan (4) lokasi titikkontrol hasil survei GPS. SINMAP menghitung indeks stabilitas tanah dengan asumsi bahwa: proses longsor merupakan hasil kombinasi dari: stabilitas lereng, karaktersitik tanah, jenis peruntukan lahan danbesarnya hujan. Pengaruh dan interaksi antara ke empat faktor tersebut diintegrasikan di dalam SINMAP dan dikaslifikasikan dalam suatu nilai indeks stabilitas tanah. Hasil studi menunjukkan bahwa: 64.7% darikawasan Sub-Das Rawatamtu berada pada zona stabil; 3.2% berada pada zona agak stabil; 3.5% berada pada zona kurang stabil; 27.1% berada pada kawasan zona batas bawah longsor; dan 1.4% berada pada kawasan zona batas atas longsor. Sebagian besar wilayah yang mencakup zona batas atas dan batas bawah longsor, berada pada lereng Gunung Argopuro dan sebagian kecil berada pada kecamatan Sumberjambe (daerah lereng Gunung Raung).Kata Kunci : Indek Stabilitas tanah, SINMAP, Longsor, Rawatamtu.Diterima: 03 Desember 2013;Disetujui: 10 Maret 2014

Abstract

This research deals with identification of potential flood discharge from 15 watersheds located in Eastern Part of East Java Province. Recorded times series of daily discharges data are used as main input for the analysis. The discharge data for each watershed are rangked from lowest to high value. Then, the value of discharge correspond to quantile 90% (Q90) is calculated and determined as the threshold level for each watershed. In this case, discharge data more than > Q90 value is categorized as flood events. Then, the frequency of flood events are calculated based on monthly or annual time interval. Furthermore, spatial distribution of flood events are visualized by comparing the frekuency of flood events amongs the watersheds. Finally, thematics maps corresponde to waterheds properties, frequency of flood events, and rainfall event are presented.Keywords: Threslod level method, waterheds, flood indice, East Java

Abstract

This research deals with identification of potential hydrological drought at 15 watersheds in Eastern part of East Java Province. Hydrological drought events is indicated by water deficits at the main river of the watersheds during certain period of record. Discharge data from 15 watersheds in East Java are used as main input for this analysis. TLM modul based on HydroOffice platform is used to calculate the deficit. Deficit event is counted when the discharge during more than > 7 days is below the threshold level. The threshold level is set up using percentile 90% (Q90). The value of Q90 is determined from discharge times series. Furthermore, the discharge is rangked from high to low flow. Results from TLM are then imported to EXCEL for further analysis. Furthermore, GIS software package (Quantum GIS) is used for mapping the spatial variation of discharge values (avarage, maximum, Q90), frequency and duration of deficits events. This analysis produces the spatial maps of discharge value and deficit events ( averaged annually).Keywords: TLM, hydrological drougth, percentile 90 (Q90), discharge

Abstract

Fiber Sieving machine is a machine which used for sieving or separating coconut fiber. The machine is made of steel and driven by an electric motor. The purpose of this research was to analyze the quality of cocofiber resulted by sieve machine fiber. The process to produced cocofiber required several stages, there were decomposition, sieving, drying, and packaging. The results showed that increasing the sieve size, generated more cocofiber, less cocopeat, and faster process. Based on ANOVA there were no different between three sieving size treatments (0,4 x 0,4) cm2, (1 x 1) cm2, (2 x 2) cm2).Keywords: sieve machine fiber, efficiency, the size of the sieve

Abstract

This research deals with the prediction of erosion level by means of USLE and GIS software. USLE was used to calculate the erosion level at the watershed level, then the result was classified and mapped on the top of ArcGIS. Two similar sub-watersheds (Kloposawit and Rawatamtu) in theeastern part of East Java were used for this study. Input data consist of: (1) ASTER GDEM2 (resolution pixel ± 30m), (2) soil map layer, (3) land uses map, (4) rainfall data, and (5) ground control points. Research procedures include (1) data inventory, (2) analysis using excel and ArcGIS,(3) calculation of erosion level, (4) field survey using GPS, and (5) interpretation. The research result shows that about 56,4 km2 (7,8%) area of Kloposawit sub-watersheds is classified as high and very high erosion level rate. This area cover 8 districts at Bondowoso Regency. Furthermore, at Rawatamtu sub-watershed, high and very high erosion level cover 7 districts in Jember Regency.Keywords: erosion rate, USLE, erosion map, watershed

Abstract

This Pre Experimental One Group Pretest-Posttest design was carried out to find the effect of Mnemonic Device Method in teaching vocabulary to the first semester students at the English Education Study Program of IKIP-PGRI Pontianak in the Academic Year of 2016/2017. The population was the first semester students and the sample was B morning class consisted of 26 students. The sampling technique used was cluster random sampling. The instrument used to collect the data was a set of vocabulary test. The data were analyzed by using descriptive statistic and inferential statistic analysis. The findings were: (1) Mnemonic Device Method was effective to teach vocabulary; the mean score of pre-test and post-test were significantly different; and (2) the different between pre-test and post-test scores had strong effects to the students vocabulary mastery especially in the first semester students of English Education Study Program IKIP-PGRI Pontianak.
