Abstract

Most of the water loss from the soil profile occurred through the evapotranspiration process especially when the plant covers were under maximum growth periods.  This study aimed to apply a technique of measuring a dielectric variable for calculating soil water content and crop water use in the coarse and medium textured soils grown with upland rice.  A couple of wires were inserted into the soil repacked in a 10-kg polybag grown with upland rice, the electrical impedance representing the dielectric value was measured using an instrument called the impedance meter.  The impedance values were converted into the soil water content using a nonlinear regression model of ? = a.ebZ where a and b were constants.  Results showed that the proposed technique of measuring the electrical impedance has successfully been applied to calculate the soil water content and the water use by upland rice grown in loamy sand and sandy loam soils.  Cumulative water loss from loamy sand was about 4 L plant-1 higher for the coarse loamy sand in the first 30 days of a measurement period, but about 10 L plant-1 higher for finer sandy loam on the 90th day of the rice growth period.  Higher biomass of upland rice in the sandy loam soil could increase the evapotranspiration rates and be the main reason for higher water use in this soil.

Abstract

Soil water availability to the plants is a very important physical property of soil that controls water and nutrient absorption by the plant.  It is defined as the difference between the maximum amount of water the soil can hold and the minimum condition that the plant can no longer extract water from the soil.  However, soil factors that control the plant available water content (PAWC) in the soil have not been fully understood.  The present study aims to analyze the relations between particle-size distributions and organic carbon with the available water of the soil and to develop a model of predicting PAWC.  Five soil profiles at different land units were described up to the depth of 100 cm.  Ten undisturbed soil samples were taken using the stainless-made core sampler from 10 cm increments for the soil water holding capacity analysis.  A similar number of disturbed samples were also provided from the same depths for soil texture and organic carbon analysis.  Results showed that the variance in PAWC could be explained by sand and clay fractions (R2>0.35) but not by silt and organic carbon contents.  Therefore, we were able to develop a model for the prediction of available water content in the soil from the sand and clay parameters.  The model will help decision-makers be able to propose conservation and management strategies for PAWC in agricultural practices as well as for the soil moisture retention at civil works.

Abstract

Understanding the relation of agroecosystem types, ages, and soil properties are vital in maintaining good quality soil. This study aims to explore the variation of selected soil properties with agroecosystem types and ages. The research has been conducted in North Bengkulu, Indonesia. Soil properties on agroecosystems of 5-yr, 10-yr, 15-yr oil palm plantation, 5-yr, 10-yr, 15-yr rubber plantation, food cropland, and scrubland were evaluated. The study found that soil in oil palm and rubber plantations of any age have a similar texture, bulk density (BD), and actual soil moisture (ASM). All plantation agroecosystems and scrubland have higher clay and lower silt content than that in food cropland. In addition, the scrubland has the highest ASM content among the agroecosystems. On the other hand, both agroecosystems enhances soil chemical properties than food cropland and scrubland as indicated by the improvement of organic-C, total-N, available P, exchangeable K and CEC of Ultisols. Older plantation also provides higher soil chemical improvement than younger one. This finding is significant for management of sub optimal soil mainly Ultisols for oil palm and rubber plantation.

Abstract

Indonesia is necessary to develop an increase in soil productivity. The decline in soil productivity for agriculture can be caused by several factors, namely land conversion to a decrease in groundwater quantity. The actual pattern of providing irrigation water with the application of dielectric sensor technology is carried out in soil cultivation to create efficiency in providing irrigation water. This research was conducted using a single factor experimental method with repeated measurements on three types of land use, such as land without vegetation, soil with tomato cultivation, and soil with grass. Measurements were carried out using an automated application of soil moisture monitoring based on dielectric technology with two measuring periods. Each measuring period consists of two weeks or fourteen days. Soil sample analysis was carried out at the Bengkulu University soil laboratory. The results of the observations were analyzed using variance (ANOVA) on the 5% F test table, the LSD test was carried out at the 5% level on data that had a significant effect. The results showed that the daily irrigation water for vegetated land was lower than for tomato cultivation and without vegetation in each measurement period. The frequency of irrigation water application in the two observation periods also showed that the land without vegetation had a higher amount and frequency of water application compared to the other two types of land use.

Abstract

Production of coffee beans in the weekly market reaches 95 tons per week. The main problem faced by the business group is the limited availability of raw materials ofselectively red coffee beans. This is because the coffee harvest only occurs in April toAugust, so that outside these months the raw materials are not available. Therefore, thestudy of the raw material supply management and ground coffee marketing managementarrangement that continuous ground coffee business needs to be done. Descriptiveresearch is conducted in this study, in order to describe in detail the actual situation. Datawas obtained from the results of in-depth interviews (depth interviews), observation, anddocumentation of the farmer and member of the group management. The study revealedthat the availability of raw materials of selectively red coffee beans quotation results isvery limited. Raw material needs can be supplied by local purchases of villages in MuaraSahung or from other coffee production center in the District of Kaur. This effort can beachieved through compliance management raw material supply and marketingmanagement arrangement.Keywords: management, raw materials, coffee powder

Abstract

Pengabdian masyarakat yang diterapkan adalah penggunaan alat pengukur kadar air biji-bijian termasuk kopi yang telah dikalibrasi agar memiliki akurasi yang tinggi.  Kalibrasi alat dilakukan agar nilai yang terbaca oleh alat dapat mendekati kadar air kopi biji sebenarnya yang ditetapkan melalui pengeringan dalam oven sehingga mampu menyelesaikan masalah yang dihadapi khalayak sasaran. Kegiatan pengabdian ini bertujuan untuk memberikan pemahaman terhadap khalayak sasaran secara teknis akan pentingnya pengukuran kadar air kopi biji sebelum dilakukan penjualan dengan menggunakan alat pengukur kadar air. Metode yang diterapkan dalam kegiatan pengabdian ini adalah koordinasi, sosialisasi dan pelaksanaan kalibrasi alat pengukur kadar air. Khalayak sasaran dalam kegiatan ini adalah Kelompok Tani Bersaudara yang berada di Dusun Napal Hijau, Desa Ulak Bandung, Kecamatan Muara Sahung, Kabupaten Kaur yang terletak sekitar 233 km arah selatan Kota Bengkulu.  Hasil dari kegiatan ini adalah adanya pemahaman, pengetahuan dan kesadaran khalayak sasaran dalam menjaga kualitas kopi biji menggunakan alat pengukur kadar air, guna memenuhi standar kadar air tingkat pedagang pengumpul kurang dari 20%.

Abstract

Seedling house is a very important thing to support plant propagation in order to realize the Sustainable Food House Area (KRPL) program. Through this service activity, the service team tries to develop a simple nursery to support the program. The objectives of this activity are (1) to determine the potential for developing a nursery to create a sustainable food house area in the Beringin Raya Village, Bengkulu City and (2) to increase the ability of the Women Farmers Group (KWT) Sustenance Bersama in managing and developing seedling houses. The method used is a PRA (Participatory Rural Appraisal) approach which is implemented through outreach activities and direct practice in the field. The results of this service activity are fostering the spirit of KWT members in optimizing the use of seed houses that have been developed by the service team and increasing community understanding and skills in utilizing seed houses through nurseries of various types of plants.
