Abstract

The fertilizer availability as source of N, P, and K nutrient where plant responsif  was difficult found by farmer. Thefore, It was needed information about nutrient availability in soil properties to know nutrient deficiency of its by maize as plant indicator. The  objective of this research was to study the respons of  N, P, and K fertilizers and the best combination of it on the growth and yield of Maize. The research conducted at Udic Pellusterts in North Isimu Tibawa District of Gorontalo Regency. The experi- mental design was following random block design that consist of 5 treatments with 3 replications. The result of this research showing that minus N, P, and K fertilizers have a significantly effect on plant age polination, the percentage of height stem of  an ear of corn to plant height and dry straw weight but did not have significantly effect on plant height and the weigh of one hundred grain of Maize. To improve the growth and yield of Maize using fertilizing without P treatment were 250 kg Urea ha-1 and 75 kg KCl ha-1 or completely dosage were 250 kg Urea ha-1, 100 kg TSP ha-1 and 75 kg KCl ha-1 as the best fertilizers combination.

Abstract

Coffee is a national strategic commodity that contributes to Indonesia’s foreign exchange, but its productivity remains low due to cultivation on low potential land. This study aimed to determine the land suitability of endemic liberica coffee using two different methods and formulate recommendations for land management in Pinogu Plateau. Thirteen land units were surveyed, and soil samples were collected and analyzed in the laboratory to identify the land characteristics. Land suitability classes (LSCs) were compared by limiting factor and parametric methods. Analysis using the limiting factor method showed that the actual LSCs for liberica coffee consisted of moderately suitable (S2) and marginally suitable (S3) classes. Efforts for improvement could increase the potential of LSC to became very suitable (S1) and S2 classes. Meanwhile, the assessment with the parametric method indicated that the LSC consisted of S1, S2, and S3 classes. These results revealed that the parametric method provides more realistic land characteristics than the limiting factor method. Land management II  or the land that had a little limiting factor turned out to be more dominant with the recommendation of adding P and organic fertilizer.

Abstract

This study aims to determine the effect of group dynamics on the institutional capacity of beef cattle farmer groups in Gorontalo Regency. This research was conducted in Gorontalo Regency in February–June 2018. The method used in this study is a quantitative method. Determination of the sample is done by multistage sampling. The number of samples is 120 members of farmer groups. Data processing using Structural Equation Modeling (SEM) analysis on the AMOS program. The results showed that group dynamics affected the institutional capacity of farmers by 0.859. Each dynamics indicator contributes a good average including clear group goals 61.4% group structure 65.6%, task function 67.6%, group development coaching 58%, cohesiveness 60.2%, atmosphere 50% , 54.3% effectiveness, 63% pressure group and 74% desire group. The institutional capacity development of farmer groups cannot be separated from group dynamics that have a positive effect. Farmer groups as a forum that has the potential to move its members to interact and work together. The level of group dynamics is quite good, but the role of breeders must be more optimal in participating in the activities of the beef cattle business group Keywords: Cattle, Group dynamics, Institutional capacity

Abstract

This study aims to determine the dose of fertilization on the growth and yield of soybeans, to determine the effect of tillage on the growth and yield of soybeans and to determine the interaction of doses of the level of use of organic fertilizers and tillage on the growth and yield of soybeans. The research was conducted using factorial group random planning method or factorial RAK. The first factor is the amount of organic fertilizer (cow stage) which is divided into four levels, namely P0 without fertilization, P1 organic fertilizer (10 tons/ha), P2 organic fertilizer (30 tons/ha). The second factor is tillage which consists of two levels, namely T0 (least tillage) and T1 (perfect tillage). Each treatment combination was repeated 3 times so that there were 24 research plots. The results showed that there was no interaction between organic fertilizers and tillage. The application of organic fertilizer significantly affected the parameters of soybean plant height, number of leaves, rate of formation of flowers and pods, number of pods per plant, weight of 100 seeds, and dry weight of the plots. Tillage significantly affected plant height, number of leaves, percentage of flower pods, number of pods per plant, and weight per 100 seeds. The application of 20 tons of organic fertilizer per hectare and intensive tillage has the best effect on the growth and yield of soybeans

Abstract

Masyarakat yang melaksanakan usahatani pada lahan dengan kategori lahan kering di Desa Huangobotu Kecamatan Kabila Bone Kabupaten Bone Bolango Provinsi Gorontalo pada umumnya belum menerapkan teknologi konservasi biopori. Aplikasi teknologi konservasi biopori merupakan upaya yang dapat dilakukan untuk meningkatkan pengembalian unsur hara dan peresapan air ke dalam tanah. Kegiatan pengabdian pembuatan lubang resapan biopori dilakukan pada masyarakat Desa Huangobotu dilaksanakan dengan 3 metode yaitu tahap sosialisasi (penyuluhan), pelatihan dan pendampingan. Tahap sosialisasi (penyuluhan) menjelaskan mengenai manfaat dan cara pembuatan biopori; tahap pelatihan melatih cara membuat lubang biopori; dan tahap pendampingan pembuatan biopori di halaman rumah warga. Dengan adanya biopori ini, masyarakat sangat memperoleh manfaatnya, yaitu air permukaan langsung terserap ke dalam tanah lewat biopori, sampah basah limbah dapur menjadi pupuk organik untuk tanaman dan tanaman nampak tumbuh subur.

Abstract

The purpose of community service is to preserve the environment by reducing the rate of erosion through planting and maintaining reforestation trees around Tunggulo reservoir which is located in a sloping topography area. The method used in this community service is to conduct counseling on the benefits of fruit trees (soursop, rambutan, and durian) in increasing the cover of vegetation canopy on the soil surface so that it can reduce the rate of soil erosion, in addition to providing economic value to the community. The results of the community service are in the form of transferring research results on reforestation tree planting and maintenance technology, in this case tree planting with weed removal only carried out around trees planted in the direction of the contour lines. Partners play an active role in this community service, especially in the technical implementation in the field. The community service program carried out was accepted by farmers. Farmers are very optimistic that they can apply what they have learned in this community service activity in the field, because this technology is very easy to apply. Planting is carried out together with local residents and maintenance is continued by students during the implementation of the KKN program. Of the three types of fruit trees planted, soursop plants have better growth compared to rambutan and durian plants
