“…The unavailability of Jatropha seeds led the group to find alternative raw materials. The research results of Leksono et al [114] about the potency of nyamplung oil as biodiesel material and the abundance of materials around the area encouraged the processing of nyamplung seeds into oil. Other than being able to access raw materials (nyamplung seeds) for the tamanu oil factory, the processor groups in Central Java and the Special Region of Yogyakarta can also supply nyamplung oil to the tamanu oil factory in Bali because they have the processing machines.…”

Indonesia’s tropical peatlands are one of the world’s largest carbon sinks, and they are facing the threat of extensive degradation and conversion. The Indonesian government is committed to peat restoration. However, restoration is still a costly, top-down approach lacking community participation, and is focused on the 3R scheme (rewetting, revegetation, and revitalization). Peatland restoration businesses are part of the innovative effort to finance this endeavor. Unfortunately, there is not much information available about the pre-conditions required to create a restoration business. This study seeks to understand the enabling conditions for the development of peatland restoration, with a focus on the tamanu oil business, and to assess whether the same situation might apply in the context of the restoration of degraded peatland. PEST analysis is used to describe the macro-environmental factors of the tamanu oil business and its development opportunities in degraded peatlands. Tamanu oil-based peat ecosystem restoration businesses offer good prospects because of the growing it has grown the bioenergy and biomedical markets, and they can cover a larger area of degraded peatland landscape. For tamanu oil businesses to succeed in peat ecosystem restoration, we recommend that policy documents at various levels include tamanu as a priority commodity for peatland restoration and alternative community businesses, followed by planting programs by all stakeholders. The government and social organizations must take positions as initiators and catalysts, establish a significant number and extent of pilot tamanu plantations, and create a mutually supportive business climate between entrepreneurs and peatland managers.

“…Selain bermanfaat secara ekologis, nyamplung memiliki potensi sebagai bahan baku biofuel dengan potensi produksi buah nyamplung antara 40 -150 kg/pohon (Leksono et al, 2010) dan rendemen apabila dijadikan biofuel sebesar 37 -48,5 % tergantung dari variasi genetik (Leksono et al, 2014). Potensi biofuel nyamplung dapat menjawab target nasional yaitu mewujudkan peranan biofuel sebesar 5 % dari kebutuhan energi (Pemerintah, 2006).…”

ABSTRAKRencana teknis kegiatan rehabilitasi lahan hutan BPDAS Tondano pada sempadan pantai mencapai 10.000 hektar, sehingga membutuhkan bibit yang sangat banyak. Nyamplung memiliki potensi sebagai jenis konservasi sempadan pantai dan dapat mendukung kebutuhan nasional dalam memenuhi kebutuhan biofuel. Namun pembibitan nyamplung di Sulawesi Utara belum optimal dan membutuhkan informasi metode sapihan yang tepat. Penelitian menggunakan rancangan acak lengkap dengan 3 faktor perlakuan, yaitu 1) Pemotongan daun terdiri dari 2 taraf, yaitu D1 (daun tersisa sepasang) dan D2 (daun masih utuh); 2) Pemotongan biji yang menempel terdiri dari 2 taraf, yaitu B1 (biji dihilangkan) dan B2 (biji masih menempel dibatang); serta 3) pemotongan akar terdiri dari 3 taraf, yaitu A1 (panjang akar sapihan 5 cm), A2 (panjang akar sapihan 10 cm) dan A3 (panjang akar sapihan 15 cm). Bibit yang digunakan berasal dari skarifikasi benih menggunakan media cocopeat sebanyak 180 batang bibit. Hasil sidik ragam menunjukkan bahwa perlakuan yang diterapkan hanya berpengaruh terhadap pertumbuhan tinggi sapihan. Daya hidup tanaman tidak dipengaruhi oleh perlakuan yang diterapkan karena semua sapihan hidup (daya hidup 100 %). Perlakuan pemotongan daun dan biji memiliki pengaruh nyata, sedangkan perlakuan akar tidak berpengaruh nyata. Perlakuan tanpa pemotongan bibit dan tanpa pemotongan biji menghasilkan respon pertumbuhan tinggi terbaik yaitu 4,60 cm dan 4,63 cm Kata kunci: Calophyllum inophyllum, daya hidup, teknik penyapihan, tinggi ABSTRACT Technical rehabilitation planning of BPDAS Tondano on coastal area has reached 10,000 hectares, thus require many seedlings. Nyamplung has potential as rehabilitation plant in coastal at the same time it can support national demand of biofuel. However the nurseries of nyamplung in North Sulawesi are not optimal and need appropriate information of weaning method. This research used completely randomized design with three treatment factors, namely 1) Cutting the leaves consist of two levels ie D1 (pair leaves) and D2 (intact leaf); 2) Cutting intact seeds, consists of two levels i.e B1 (removed seed) and B2 (intact seeds); and 3) Cutting the roots lenght consist of three levels i.e A1 (5 cm), A2 (10 cm) and A3 (15 cm

Reliable data on CO2 quantification is increasingly important to quantify the climate benefits of forest landscape restoration and international commitments, such as the Warsaw REDD+ Framework and Nationally Determined Contributions under the Paris Agreement. Calophyllum inophyllum L. (nyamplung as a local name or tamanu tree for the commercial name) is an increasingly popular tree species in forest landscape restoration and bioenergy production for a variety of reasons. In this paper, we present allometric equations for aboveground biomass (AGB), belowground biomass (BGB), and total above- and belowground biomass (TABGB) predictions of C. inophyllum L. Data collection was carried out twice (2017 and 2021) from 40 trees in Java, Indonesia. Allometric equations using the natural logarithm of diameter at breast height (lnDBH) and ln height (lnH) for biomass prediction qualified the model’s fit with statistical significance at 95% of the confidence interval for AGB, BGB, and TABGB predictions. The results showed that the linear models using both lnDBH and lnH were well fit and accurate. However, the model with lnDBH is more precise than the model using lnH. Using lnDBH as a predictor, the R2 values were 0.923, 0.945, and 0.932, and MAPE were 24.7, 37.0, and 25.8 for AGB, BGB, and TABGB, respectively. Using lnH as a predictor, the R2 values were 0.887, 0.918, and 0.898 and MAPE were 37.4, 49.0, and 39.8 for AGB, BGB, and TABGB, respectively. Consequently, the driven allometric equations can help accurate biomass quantification for carbon-trading schemes of C. inophyllum L.
