The rate of world population growth gets faster every year, while on the other hand the land available for food production activities is increasingly limited. Efforts to increase income and food crop production by using cocoa farming to support national food security can be done by optimizing of land through crop diversification patterns by planting local tubers under cocoa farming. This research aims to analyze the optimization of land use, revenue and production costs. In addition, analyzing the nutritional content contained in each type of local tubers, namely sweet potato, cassava and taro. The research was conducted in the the buffer zone of Lore Lindu National Park (TNLL), Palolo District, Sigi Regency, Central Sulawesi Province, Indonesia. The results showed that the optimization of land use and revenue was obtained through the diversification pattern of sweet potato and cocoa. Optimization of the costs use occurs in the use of fertilizer production inputs. In addition, sweet potatoes have a higher calorific value, protein and fat compared to cassava and taro. However, the carbohydrate content of cassava is higher than that of sweet potato and taro.

Community Readiness Model (CRM) is a research method widely used in the field of public health. The purpose of the paper therefore is to review the implementation of CRM in Social Forestry field (SF) of Central Sulawesi Province, Indonesia by considering the unique intersections between the two concepts. Qualitative Systematic Review was used in this study involving 169 documents obtained through the search of electronic sources. The main result was on combining the dimensions of both the CRM and SF to produce an integration model which intersects and transforms social values, culture, traditions, and behaviour. Social innovation involving network, strategy, solidarity, and collective identity was intersected between the dimensions of CRM and SF to consider the intrinsic values of the village community. These four components were specifically related to partnership, governance, resilience, community and policymaker, livelihood, social cohesion, and integration. The application of CRM to Social Forestry in Central Sulawesi has the ability to optimize local wisdom teaching about the change and harmony of life to provide a balance between humans and nature.

Kelompok tani yang menjadi mitra dalam pelaksanaan kegiatan ini adalah Bina Tani. Permasalahan yang dihadapi adalah seringnya terjadi longsor di areal hutanrakyat dan kebun rakyat yang menyebabkan produktivitas lahan semakin berkurang serta kurangnya pengetahuan masyarakat dalam menerapkan teknik konservasi terpadu pada hutan dan kebun rakyat. Program kemitraan masyarakat (PKM) ini bertujuan untuk melakukan diseminasi teknologi usahatani konservasi lahan terpadu untuk meningkatkan pengetahuan dan keterampilan masyarakat. Metode yang diterapkan adalah pelatihan, pelaksanaan demplot pertanian konservasi, pendampingan dan pembinaan yang dilakukan secara partisipatif. Pada kegiatan pelatihan dan demplot diberikan materi mengenai teknik konservasi tanah seperti pembuatan kontur, teras, penggunaan pupuk yang teratur, pembuatan dan pengelolaan drainase, penanaman dalam strip, tanaman penutup tanah dan pemilihan pergiliran tanah yang cocok. Hasil pelaksanaan PKM menunjukkan bahwa pelaksanaan diseminasi sangat dirasakan manfaatnya oleh masyarakat karena meningkatkan pengetahuan dalam mengurangi risiko bencana (mitigasi) khususnya bagi yang bermukim di kawasan rawan longsor.

Local communities around the Lore Lindu National Park have practiced agroforestry, including candlenut and coffee, which benefited not only for the livelihood of the communities but also for conservation of the national park area. This study aims to analyze the community readiness by the actors of each agroforestry system as a reference for the development of the two agroforestry systems. Based on the CRM approach, the community of candlenut agroforestry actors had a higher level of readiness (6.2 and 5.1) compared to coffee agroforestry actors have (4,9 and 4,7). The t-test analysis shows the difference between the five CRM dimensions. Those indicate that knowledge is significantly different between the readiness level of both the candlenut and coffee agroforestry communities. The value of the knowledge dimension in the candlenut agroforestry community is greater than the readiness value of the coffee agroforestry community. The knowledge factor is the most critical dimension to get attention in the agroforestry development effort.

Pengelolaan sumberdaya alam akan memberikan manfaat dimasa yang akan datang, maka perlu dikelola dengan baik sehingga fungsinya dapat terpelihara sepanjang masa. Salah satu sumberdaya alam yang harus mendapatkan perhatian lebih adalah Daerah Aliran Sungai. Tujuan penelitian ini adalah untuk mengetahui arahan pemanfaatan lahan Sub DAS Olonjonge dan kesesuaian penggunaan lahan aktual terhadap arahan pemanfaatan yang dibuat.. Hasil overlay peta jenis tanah, lereng dan intensitas hujan di dapat arahan pemanfaatan lahan yaitu Kawasan Lindung seluas 2.026,40 Ha, Kawasan Penyangga seluas 615,51 Ha, Kawasan Budidaya Tahunan seluas 235,63 Ha, Kawasan Budidaya Semusim seluas 515,08 Ha. Evaluasi pemanfaatan lahan pada Kawasan lindung yang sesuai adalah hutan seluas 2010,73 Ha atau 99,23%, tidak sesuai kebun coklat seluas 15,67 ha atau 0,77 %, Kawasan penyangga penggunaan lahan yang sesuai adalah hutan seluas 220,06 Ha atau 35,75 %, tidak sesuai kebun coklat seluas 394,08 Ha atau 64,03 %, dan kebun campuran sesuai bersyarat yang seluas 1,37 Ha. Kawasan budidaya tahunan penggunaan lahan aktual yang ditemui adalah kebun coklat seluas 135, 10 Ha (sesuai) dan kebun campuran seluas 100,53 Ha (S), Kawasan budidaya  semusim penggunaan lahan yang sesuai  adalah permukiman seluas 29,63 Ha, kebun campuran seluas 421,68 Ha, kebun coklat seluas 33,93 Ha, sawah seluas 18,21, hutan seluas 11,62 Ha.
