Natural silk farming is a series of silk agro-industry activities from mulberry cultivation, silkworm maintenance, cocoon production and processing, silk spinning and weaving. Many supporting factors for the development of natural silk in Indonesia. However, the natural silk industry is getting worse with high import values. The main problem is the low quality of silkworm egg seeds. The Forest Research and Development Center (P3H) is a government agency authorized for natural silk commodity development. This study aims to describe the efforts of conservation and breeding of natural silkworm in Indonesia. The material used for conservation is the germ plasma silkworms collection owned by P3H. Whereas for breeding activities, silkworms used are produced from conservation activities. Conservation is carried out using eggs of the same type of strain in the germ-plasma, while breeding is done by crossing various types of moths. The result of conservation is the maintenance of 58 germ plasma silkworms. While breeding results are a type of hybrid caterpillar PS 01, which has a production advantage compared to commercial types CS 03. The dissemination of results such as hybrid PS 01, which has a comparative advantage needs to be improved to help overcome the problem of Indonesian silkworms.

Agroforestry is a win–win solution in terms of restoring forest function while benefiting the local community. This research aimed to (1) understand the regulations concerning protected area management and the restoration strategies adopted based on the history of forest degradation in the area, (2) investigate the factors driving local people to adopt agroforestry systems in the area, and (3) investigate the characteristics of the agroforestry system developed and its impacts based on farmers’ perceptions. This research was performed in Wan Abdul Rachman Grand Forest Park, Lampung Province, Indonesia, and involved interviewing 59 respondents who managed 63 agroforestry plots in the area. Several schemes had been implemented to restore the degraded forest without involving the community, and the results were unsatisfactory. Changing the regulations concerning managing conservation forests to involve the community and providing legal permits and support from the management improved forest function due to community willingness to implement the agroforestry system. About 81% of observed plots consisted of 5–12 plant species, and 16% of plots consisted of 13–16 species per plot. Theobroma cacao was the most common species in the agroforestry plots, followed by Durio zibethinus, Parkia speciosa, and Aleurites moluccana. The size of the agroforestry plot affected the number of species in the plot. The community perception demonstrated that agroforestry has positive impacts on livelihood, the environment, and biodiversity at the landscape level.

Community access to the land of Wan Abdul Rachman Grand Forest Park has started since a long time ago. Since 1998, the community has been permitted to use the land by emphasizing the sustainability aspect. Complex agroforestry systems have been established by combining several tree crops; most of them are food-producing plants. This research was aimed to study the composition and characteristics of the food-producing plant species, canopy strata, and its regeneration rate in the context of an agroforestry system. The research was conducted at two villages; those were Bogorejo and Cilimus, located in Pesawaran District, Lampung Province, from March to November 2018. Data collection was done through field observation and structured interviews with 59 farmers as respondents who managed the grand forest parkland. Data analysis was conducted using quantitative descriptive analysis method. The results showed that the complex agroforestry practices characterized by three canopy layers and one understorey. The mature food-producing plant species proportion was 86.85% of the total food-producing plants with plants density 735.97 individuals/ha. The density of tree crops population 847.42 individuals/ha with the highest density was found for coffee, cacao and candlenut. The existence of immature food-producing plants species was only 13.15%, indicating that the regeneration process had been initiated and conservation effort of the grand forest park still on-going.

The domestic silkworm or mulberry silk moth, B. mori L., provides more than 99% of the world’s silk. Silk, as a sericulture product, was first introduced in Indonesia through a trade mechanism and began to develop in 1953. Several factors (economic, ecological, market, and cultural) support sericulture and make it become one of the non-timber forest product priorities. However, the competitive advantages alone have not encouraged the development of prospective sericulture industry in Indonesia yet. This paper is a review of tropical sericulture development in Indonesia. The literature on the development of sericulture in Indonesia between 1989 and 2022 is used to describe conditions related to mulberry cultivation (moriculture), and silkworm rearing (sericulture), as well as the state of socio-economic development, culture, and institutions. Moriculture and sericulture techniques, socio-economic aspects, institutional arrangements, and community motivations are intertwined, creating a challenging atmosphere for sericulture development. There are potential resources, such as exploring quality mulberry production and quality silkworm production through research and development, valuable cultural aspects, and potential stakeholders to build network engagement. Commitment, cooperation, and action from all stakeholders are needed to enhance the development of sericulture in Indonesia. In this context, the central government can play an important role in facilitating multi-stakeholder partnerships in the development of integrated sericulture in Indonesia.

Hybrid silkworm varieties, mulberry species, environmental factors, and rearing factors are essential for the cocoons’ quality. The species of silkworm feeding is a key factor in the sericulture industry, so the suitability of mulberry species for each silkworm hybrid species needs to be known. This study aimed to determine the effect of mulberry species on silkworm growth and quality of cocoons BS 09. The research method used was a randomized block design with four species of mulberry: Morus bombycis var Lembang, M. cathayana, M. multicaulis, and M. alba var Kanva 2 and one control species (mixed mulberry species). The research was carried out at Dramaga Research Forest, Bogor Regency. The determined parameters were the percentage of rearing, larva weight, cocoon weight, cocoon shell weight, and percentage of cocoon shell. The experiment results showed that the percentage of rearing was 97.5%-100% for all species of mulberry. The best result of the cocoon weight was feed treatment of M. multicaulis (1.89 g), but it was not significant with feed treatment of M. bombycis var Lembang or M. cathayana or M. alba var Kanva 2. M. cathayana feed treatments give the best results for the cocoon shell weight (0.44 gram) and percentage of cocoon shell (22.82%).
