Cabai menjadi bagian dari kebutuhan makanan keseharian, tetapi produksinya masih rendah. Penilian kesesuaian lahan beserta kelayakan usahatani tipe penggunaan lahan (TPL) cabai rawit menjadi tujuan penelitian ini yang berlokasi di Kecamatan Pinolosian Kabupaten Bolaang Mongondow Selatan. Metode survei tanah diterapkan dengan observasi lahan dan pengambilan sampel tanah, serta survei usahatani cabai. Analisis kesesuaian lahan dengan memadankan antara kriteria kesesuaian lahan dengan karakteristik lahan sampai didapatkan kelas kesesuaian lahan aktual dan potensial, sementara R/C rasio digunakan untuk menilai kelayakan usahataninya. Hasil yang diperoleh bahwa TPL cabai rawit yang terpilih dengan kesesuaian aktual hanya kelas sesuai marjinal (S3) seluas 3.608,14 ha dan kelas kelas tidak sesuai (N) seluas 33.584,24 ha dengan curah hujan, drainase, N total, pH, P2O5, tekstur, kedalaman tanah, dan bahaya erosi sebagai faktor pembatas. Meskipun N total, dan pH dapat diperbaiki, tetapi faktor pembatas lainnya sulit diperbaiki, sehingga kelas dan luas kesesuaian lahan potensial sama. Budidaya cabai rawit menguntungkan karena nilai R/C 2,0 (R/C > 1), sehingga layak diusahatanikan. Dengan demikian, berdasarkan kelas kesesuaian lahan dan kelayakan usahatani cabai rawit ini, maka budidaya cabai rawit dapat dikembangkan pada lahan yang sesuai yang tersebar di wilayah tengah dan barat Kecamatan Pinolosian.

This research was conducted in Wanggarasi Sub-district, Pohuwato Regency, Gorontalo Province, specifically in Bohusami Village and Bukit Harapan Village. The objectives of this study were (1). To analyze the biophysical land conditions (land capability, land suitability, land carrying capacity, production), as well as the social conditions of the community, particularly population pressure, which can support a sustainable maize land-use system. (2). To develop an appropriate model for optimizing sustainable maize cultivation in Wanggarasi Sub-district, Pohuwato Regency, Gorontalo Province. The method used was land evaluation with a land unit approach. Sampling locations were determined using stratified random sampling, considering land units at the study sites—namely, slope, landform, and land use. The preparation of land capability maps, land suitability maps, and land optimization maps was carried out through interpretation of RBI maps, administrative maps, land unit maps, and LCLP analysis results. Meanwhile, maps of land carrying capacity, population pressure, and production were developed based on RBI maps, administrative maps, and secondary data. Data analysis was conducted using ecological spatial analysis with Geographic Information System (GIS) and supporting socio-economic data were analyzed descriptively. The research results showed that the study area is dominated by land with low optimization categories (R), expressed through the functional formula: OPT (R) = f (KL (III, IV) + KS (S3, N1) + DDL(R) + P(R) + TP(R)). The models and strategies for optimizing land in the low category (R) can be implemented through: (1) Identifying land units combining dry fields and rainfed areas that ensure the availability of land with high (T) or moderate (S) optimization categories, with a minimum area approximately equal to that of land units categorized as moderate or low in the sub-district. (2) Identifying land-use combinations that can yield production categorized as high (T) or moderate (S) land optimization by converting part of the coconut plantation area—particularly those needing replanting—into dryland maize cultivation. Additionally, seeking land-use combinations that ensure the availability of land areas with moderate optimization category (S), such as mixed gardens and dry fields.

The availability of high-quality mango seedlings is a major challenge in improving fruit yield and quality, which can be addressed through vegetative propagation techniques, such as grafting that combines rootstocks with strong root systems and scions from superior varieties. This study aimed to determine the effects of the interaction between cover type and rootstock height on mango grafting success. This study was conducted from July to September 2022. A split-plot design was employed, with the main factor being the cover type (single and mass cover) and the sub-factor being the rootstock height (50 cm and 30 cm). The measured parameters included the time for bud emergence, percentage of bud emergence, number of leaves, and grafting success, with data analyzed using ANOVA and LSD tests at a 5% significance level. The results showed that mass cover significantly influenced grafting success, with an average time of bud emergence of 12.40 days, percentage of bud emergence of 100%, average number of leaf average of 6.90, and grafting success rate of 100%. Conversely, the rootstock height did not significantly affect these parameters. Mass cover has been proven to create an optimal microenvironment for plant growth by maintaining humidity and temperature and protecting plants against extreme environmental conditions. In contrast, grafting incompatibility was detected in certain rootstock height treatments, potentially affecting the nutrient flow and graft quality. In conclusion, mass cover had a dominant effect on grafting success, whereas rootstock height had no significant impact. No interaction was found between cover type and rootstock height in mango grafting. Keywords: cover type, rootstock height, grafting

In the Updated NDC (UNDC) document, Indonesia's GHG emission reduction target with its own capabilities of 29% increased to 31.89%, while the target with international support of 41% increased to 43.20%. The climate resilience of the agricultural sector is very important where food security, economic and ecological stability and sustainable development are greatly threatened by climate irregularities. Technological innovation in agricultural activity models by considering location-specific aspects by combining various aspects so that they can further increase optimal carbon absorption is an understanding of carbon efficient agricultural technology. The aim of the service activities is to build capacity and participation at the farmer level through carbon efficient agricultural technology programs in the context of efforts to implement NDC to achieve climate resilience in the agricultural sector. The implementation of collaborative service activities in nggulo village, Tilongkabila District, Bone Bolango Regency will take place from May to June 2023. The number of students involved is 10 from the Agrotechnology study program, Faculty of Agriculture, Gorontalo State University. The method used in this collaborative service activity is participatory training with activities in the form of counseling and technical guidance. The form of program implemented includes a carbon efficient agricultural technology program including agricultural land optimization activities in the form of increasing the cropping index through the jajar legowo technique and biopesticide techniques. Land management in the form of biopore techniques. The result of this activity is a carbon efficient agricultural technology program in the form of the jajar legowo technique which can be implemented by farmers which is applied to tomato and land kale plants using the jajar legowo technique 2 : 1 and 3 : 1. The jajar legowo system is applied by planting with a pattern of several rows of plants interspersed one empty row as legowo which has the function of being a space for plant management in the form of weeding, irrigation and HPT control activities. In biopesticide activities, soursop extraction can be used as an organic insecticide. In biopore activities, this technique is not only used as water absorption, but also as soil fertilizer, reduces the accumulation of waste which causes various health problems and plays a role in maintaining soil water levels from the threat of drought. Based on the results of activities, the carbon efficient agricultural technology program can be one of the efforts to implement NDC at the site level through empowering farmers to build capacity and independent participation to achieve climate resilience in the agricultural sector.

The current land suitability criteria for konjac are incomplete and fail to consider land dimensions and quality, which influence optimal yield. This research aims to develop criteria for konjac land suitability based on the dimensions, quality, and characteristics of selected land. In Gorontalo Province, Indonesia, 131 land units were surveyed to obtain data on the quality and characteristics. Selection of land dimensions, quality, and characteristics using Structural Equation Modeling (SEM) with Partial Least Squares (PLS). Meanwhile, the optimum yield and distinguished land suitability criteria for konjac plants using the boundary line method. The results indicated that intrinsic and extrinsic dimensions determined the new land suitability criteria. In the intrinsic dimension, land quality was assessed based on root conditions, oxygen availability, nutrient availability, nutrient retention, and sodicity. For the extrinsic dimension, land quality only comprised temperature, water availability, land preparation, and erosion hazard. Land characteristics in the intrinsic dimension consisted of soil drainage, texture, bulk density, particle density, porosity, pH, organic C, CEC, base saturation, total N, available P, and exchangeable K. For the extrinsic dimension, land characteristics included slope, soil erosion, surface rocks, and rock outcrops. The highest optimum yield of konjac was 9.17 t/ha, and the lowest was 6.69 t/ha, respectively.

The agricultural sector is the third-largest contributor to greenhouse gas (GHG) emissions among the five major emitting sectors. In 2022, Indonesia strengthened its national commitment through the Enhanced NDC 2022, targeting a 31.89% reduction in emissions under the unconditional scenario and 43.20% under the conditional scenario with international support. Without significant climate-mitigation actions in agriculture, the goals of the Paris Agreement cannot be achieved. This community service program (Thematic Community Service Program – Phase 2) was conducted in Boidu Village, North Bulango District, Bone Bolango Regency, Gorontalo Province, for 45 days using training and mentoring approaches to support the application of scientific and technological innovations. The activities also served as action research to promote Climate Smart Agriculture (CSA) technologies, including agroforestry systems, water-harvesting techniques (biopores and rorak pits), and the decarbonization of rice straw and husks. This program successfully demonstrated the practical implementation of CSA as a strategy for climate-change mitigation and adaptation in the agricultural sector. Three key technologies—agroforestry, water harvesting (biopores and rorak), and straw/husk decarbonization—were shown to produce synergistic benefits. Agroforestry enhances ecosystem complexity and carbon stocks, water-harvesting techniques optimize hydrological cycles and reduce erosion, and the decarbonization of straw and husks converts agricultural waste into biochar, functioning as long-term carbon storage while improving soil fertility.
