Peningkatan populasi ternak sapi dapat dilakukan melalui kegiatan Inseminasi Buatan (IB) yang diharapkan juga dapat meningkatkan hasil kotoran ternak (feases) sebagai sumber bahan baku pupuk organik. Kegiatan ini bertujuan untuk: (1) meningkatkan populasi ternak sapi sebagai penghasil bahan baku pupuk organik, dan (2) meningkatkan pengetahuan Kelompok Tani Sumber Rezeki dalam pembuatan pupuk organik. Kegiatan ini dimulai bulan Maret sampai Agustus 2019 di Desa Bualo Kecamatan Paguyaman Kabupaten Boalemo. Kegiatan ini terdiri dari: (1) Kegiatan IB terhadap sapi induk yang sehat dan siap (masa birahi) oleh inseminator., dan (2) Pembuatan pupuk organik yang dilakukan melalui kegiatan pelatihan dan pendampingan. Sebelum dan sesudah pelatihan, dilakukan tes tingkat pengetahuan tentang pupuk organik kepada 25 orang peserta pelatihan yang dianalisis menggunakan Skala Likert. Bahan pembuatan pupuk organik meliputi: limbah jagung, bungkil kakao, feases, urin, EM4, gula dan air. Semua bahan dicampur merata dalam bak fermentasi, ditutup dengan terpal dan dibiarkan selama 3 minggu. Selama kegiatan berlangsung, antusias peserta dalam mengikuti seluruh kegiatan sangat tinggi dengan capaian 100%. Kegiatan IB telah menghasilkan sebanyak 12 ekor sapi bunting. Kegiatan pelatihan dan pendampingan kepada petani di Kelompok Tani Sumber Rezeki telah mampu meningkatkan pengetahuan tentang pembuatan pupuk organik dengan capaian sebesar 88,0% dari total peserta pelatihan.Kata kunci: Populasi, Sapi, Inseminasi Buatan, Pengetahuan, Pupuk Organik. 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. Keywords: Population, Cow, Artificial Insemination, Knowledge, Organic Fertilizer.

Tomato (Lycopersicum esculentum Mill) is the most popular agricultural product with a high economic value in society. Thus, this study aims to determine the effect and interaction of adding coconut water and cow manure on the growth and yield of tomato plants. This research was conducted from August to October 2021 at Putri Mandiri Green House, Sipatana Subdistrict, Gorontalo City using a Factorial Completely Randomized Design (CRD). The interval of adding coconut water consisted of 3 levels, while the adding of cow dung manure consisted of 4 levels. The results of this study indicated that the interval of adding coconut water and cow manure affected the growth and yield of tomato plants. It is further explained by the following results: 1) The interval of giving coconut water every 8 days has an effect on plant height, 2) The treatment once every 4 days has an effect on the number of leaves of tomato plants, 3) The adding of cow manure in the treatment of 120 g polybag-1gave an effect on the number of leaves, number of fruits, and fruit weight per tomato plant, and 4) The treatment of 60 g polybag-1 had an effect on the fruit weight of tomato plants. Besides, the interaction of treatment intervals of adding coconut water and cow manure did not affect the growth and yield of tomato plants.Keywords: Tomato Plants, Coconut Water, Cow Manure

The significant effect of land quality on maize production has not been fully considered in the existing land suitability criteria. Therefore, this study aims to determine land suitability criteria for hybrid maize in Boalemo Regency based on the optimum yield and land quality. It was carried out in Boalemo Regency, Indonesia, where the land unit of 67 units was surveyed to obtain land characteristics data. A partial least square of structural equation model (PLS-SEM) with SmartPLS 8.0 was used to select a robust land quality controlling hybrid maize yield, while the boundary line method was used to determine optimum yield and differentiating of land suitability criteria. The result showed that land qualities that define the optimum yield of hybrid maize were root conditions, nutrient availability, nutrient retentions, land preparation, and erosion hazard. The soil characteristics were effective depth, coarse material, organic C, total N, K exchangeable, slopes, soil erosion, rock outcrops, and surface rocks. Furthermore, the highest optimum yield of 8.54 ton/ha was achieved by the total N and slopes for a very suitable class (S1), while the lowest of 5.58 ton/ha was obtained by exchangeable K for class S1. This showed that the combination of PLS-SEM and boundary line analysis was a better approach to developing new land suitability criteria for hybrid maize.

Limbah pertanian, terutama jerami jagung (tebon) yang sangat melimpah dapat dimanfaatkan sebagai bahan baku pakan silase, tetapi masih banyak petani yang belum tahu dan belum bisa untuk membuat pakan silase tersebut. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan pengetahuan dan ketrampilan petani dalam pembuatan pakan silase di Kelompok Tani Rukun Sejahtera Desa Bualo Kecamatan Paguyaman Kabupaten Boalemo. Guna mencapai tujuan tersebut, maka metode pengabdian masyarakat yang digunakan adalah metode pelatihan dengan teknik ceramah dan tanya jawab, metode praktikum dan pendampingan kepada peserta, serta metode survei menggunakan instrumen kuisioner untuk menilai pengetahuan dan ketrampilan peserta dalam pembuatan pakan silase. Hasil yang diperoleh menunjukkan bahwa pelaksanaan kegiatan pelatihan dan praktek pembuatan pakan silase terbukti telah mampu memberikan peningkatan pada pengetahuan dan ketrampilan masyarakat, terutama petani tentang pakan silase dan pembuatannya. Tingkat pengetahuan petani tentang pakan silase sebelum pelatihan dilakukan mayoritas peserta pelatihan (94,4%) tidak tahu dan sangat tidak tahu tentang pakan silase. Setelah mengikuti kegiatan pelatihan, maka mayoritas peserta pelatihan (99,2%) sudah tahu dan sangat tahu tentang pakan silase. Tingkat ketrampilan petani setelah mengikuti praktek dan pendampingan pembuatan pakan silas, mayoritas (90,4%) sudah bisa dan terampil dalam membuat pakan silase. Guna tindak lanjut dari kegiatan ini, maka perlunya pendampingan terus menerus kepada kelompok tani baik oleh penyuluh pertanian maupun perguruan tinggi agar limbah jagung dan limbah pertanian lainnya dapat dimanfaatkan sebagai pakan silase; dan (perlunya pengkayaan bahan pakan silase agar kandungan nutrisi pakan silase ini lebih lengkap (komplit)
