Abstract

Rice crops require sufficient amount of water for their development, but water is often a limitingfactor if it is grown on dry Vertisol soils. The study aimed to determine the monthly wateravailability and water available of soil profiles for paddy on Endoaquert Ustic of Paguyaman. Theresearch was conducted on 2 pedon of Vertisol soil profiles, which were pedon from SidomuktiVillage of Mootilango District of Gorontalo Regency and from Sosial Village of PaguyamanDistrict of Boalemo Regency. The soil profile was constructed and sampled according to soil surveyprinciples. Climate data were collected from the Sidodadi and Molombulahe climate stations,including: rainfall data (mm), temperature (°C), relative humidity (%) and wind speed (km hour-1).Soil data used, including: soil water content of field capacity (pF = 2.5) and permanent wilting point(pF = 4.2) and root depth on 30 cm (rice roots). Monthly water availability analysis was using waterbalance method followed by water balance of soil profiles. The results showed that monthly wateravailability of Vertisol from Sidomukti Village was higher than Vertisol from Social Village. Wateravailable of Vertisol soil profile from Sidomukti Village more by 41.09% compared to Vertisolfrom Social Village.

Abstract Increasing cattle population can be done through Artificial Insemination (IB) activities which are also expected to increase livestock manure yields (feases) as a source of raw material for organic fertilizer. This activity aims to: (1) increase the population of cattle as a producer of raw materials for organic fertilizer, and (2) increase the knowledge of Sumber Rezeki Farmer Groups in making organic fertilizer. This activity began in March to August 2019 in Bualo Village, Paguyaman District, Boalemo Regency. This activity consists of: (1) IB activities towards healthy and ready mother cows (incubation period) by inseminators, and (2) Making organic fertilizer carried out through training and mentoring activities. Before and after the training, a knowledge level test about organic fertilizer was conducted on 25 trainees who were analyzed using a Likert Scale. Organic fertilizer manufacturing materials include: corn waste, cocoa meal, feases, urine, EM4, sugar and water. All ingredients are mixed evenly in a fermentation tank, covered with tarpaulin and left for 3 weeks. During the activity, participants' enthusiasm in participating in all activities was very high with 100% achievement. IB activities have produced as many as 12 pregnant cows. Training activities and assistance to farmers in the Sumber Rezeki Farmer Group have been able to increase knowledge about making organic fertilizer with an achievement of 88.0% of the total training participants.

ABSTRAK

Pemberdayaan petani merupakan salah satu upaya untuk menjadikan petani lebih berdaya dan mengurangi ketergantungan terhadap subsidi pemerintah serta meningkatkan partisipasinya dalam pembangunan, tetapi sering sulit dijalankan karena tingkat pengetahuan dan ketrampilan petani masih rendah. Kegiatan ini bertujuan untuk: (1) meningkatkan pengetahuan petani tentang pupuk organik, dan (2) meningkatkan ketrampilan petani dalam pembuatan pupuk organik. Kegiatan ini dilaksanakan pada bulan Juli 2019 di Kelompok Tani Rukun Sejahtera Desa Bualo Kecamatan Paguyaman Kabupaten Boalemo. Kegiatan ini berupa pelatihan pembuatan pembuatan pupuk organik yang dilakukan melalui ceramah dan praktek (demonstrasi). Sebelum dan sesudah pelatihan, dilakukan tes tingkat pengetahuan tentang pupuk organik dengan menggunakan kuisioner kepada peserta pelatihan. Penilaian pengetahuan peserta didasarkan pada lima item pertanyaan, yaitu: 1). Pengetahuan tentang pupuk organik; 2). Penggunaan pupuk organik; 3). Sumber bahan pupuk organik; 4). Kandungan hara dalam pupuk organik; dan 5). Jenis pupuk organik. Jumlah peserta pelatihan adalah 25 orang yang semuanya dijadikan sampel. Analisis data meliputi: analisis validitas, reliabilitas, dan analisis tabel menggunakan software SPSS 23. Tingkat pengetahuan peserta dilakukan dengan analisis skor terhadap jawaban pertanyaan menggunakan Skala Likert dan digambarkan dalam garis continuum. Praktek pembuatan pupuk organik dilakukan dengan pendekatan learning by doing. Bahan yang digunakan meliputi: limbah jagung, bungkil kakao, feases, urin, EM4, gula dan air. Limbah jagung dan bungkil kakao dicacah dengan mesin copper, kemudian semua bahan dicampur dan diaduk dalam bak fermentasi sampai merata dan percikkan dengan air sampai lembab merata serta ditutup dengan terpal dan dibiarkan selama 2-3 minggu untuk proses fermentasi dan pengomposan. Hasil kegiatan menunjukkan sebelum pelatihan, mayoritas peserta pelatihan (7 6,0%) tidak tahu tentang pupuk organik, sedangkan setelah pelatihan dan prektek pembuatan pupuk organik, mayoritas peserta pelatihan (88,6%) sudah tahu tentang pupuk organik dan cara pembuatannya. Tingkat ketrampilan petani dalam pembuatan pupuk organik juga telah meningkat yang ditunjukkan oleh indikator kemampuan mengoperasikan perangkat mesin pencacah, kemampuan memformulasikan dosis atau takaran bahan baku pupuk berupa larutan EM4+molase+air, kemampuan mencampuradukan bahan-bahan pupuk organik secara merata, dan kemampuan mengidentifikasi keberhasilan pupuk organik yang dibuat.

Kata Kunci: Pengetahuan, ketrampilan, petani, pupuk, organik.

Abstract

Maize cultivation has been carried out on the mountainous slopes with high fertilizer inputs, but maize productivity is still low. This study investigates the effect of slope and NPK compound fertilization as well as the best combination of growth and yield of local maize, relative agronomic effectiveness (RAE) percentage and economic fertilizer effectiveness (EFE) ratio in Inceptisol Bumela Indonesia. Slope variations (0-8, 8-15, 15-35, >35%) are combined with compound NPK fertilizer levels (0, 50, 100, 150, 200 kg ha-1) with split plot design. Growth data was recorded for changes in plant height and leaves number from 7 DAP to 42 DAP, while yield and yield components are recorded at harvest. The results showed that slope and NPK compound fertilization can increase the growth and yield of maize plants. The combination of flat slopes and fertilizer level of 100 kg ha-1 was the best combination in increasing plant height and the leaves number, accelerate the age of male and female flowering flowers, cob weight, grain yield and percentage of cob weight to grain yields. This combination was also able to increase the percentage of RAE, the ratio of EFE subsidized and non-subsidized. If farmers will continue to cultivate maize on the sloping land, it was recommended to arrive at hilly land with a fertilizer level of 100 kg ha-1 only.

ABSTRACT

The challenge of composite maize developing in the future is the low productivity because the maize is grown on land that is not suitable for land quality. This study aims to determine the land quality and land characteristics that control the composite maize productivity in Gorontalo Province. A total of 33 land units were surveyed and their land observed to obtain data on morphology and soil characteristics, climate and terrain characteristics, as well as composite maize productivity data through ubinan plots and direct interviews with maize farmers. Partial least square of structural equation models (PLS-SEM) analysis has been used to determine the land quality and land characteristics that control the composite maize productivity through variable validity and reliability tests, as well as structural model tests. The results showed that the manifest variables were air temperature, rainfall, wet months, dry months, LGP, drainage, coarse materials, effective depth, pH H2O, pH KCl, C-organic, total N, available P, available K, ESP, slopes, soil erosion, inundation height, inundation time, surface rock, and rock outcrops were valid and able to explain well the latent variables. Furthermore, the latent variables were temperature, water availability, oxygen availability, nutrient retention, nutrients availability, sodicity, erosion hazard, flood hazard, and land preparation used has good composite reliability and high reliability because of the composite reliability and alpha cronbach >0.6. Land quality that controls the composite maize productivity based on the order of importance were nutrient retention, rooting media, land preparation, and nutrients availability. Meanwhile, land characteristics that control the composite maize productivity based on the order of importance were pH KCI, coarse material, rock outcrops, effective depth, surface rock, available K, and soil texture. Soil texture, effective depth, pH KCI, and available K has a positive relationship and has a significant to very significant effect on the composite maize productivity, while the content of course materials, surface rock, and rock outcrops has a negative relationship and has a significant effect on the composite maize productivity.

Keywords: Quality, characteristic, land, productivity, maize, composite.
