The research was conducted in The Regency of Gorontalo in 2019 and used a qualitative research method with an inductive approach through participatory observation of farmers' farms, industry, and their environment, as well as interviews with informants selected by the snowball method. The results showed that the strategy for improving the performance of the supply chain of fresh coconut and coconut products through vertical integration by improving supply chain performance and the flow of coconut product price information to reduce uncertainty, supported by a digital information system; and by improving the flow of supply of fresh coconut with the development of formal strategic partnerships between the processing industry and the organization of smallholders and collectors-suppliers. Partnership development requires the development of smallholder organizations, collectors-suppliers, harvest, and logistics service institutions to support the vertical integration of supply chains towards equitable balance. This strategic partnership is expected to encourage the flow of goods, finance, and information can take place properly.Keywords:   coconut processing industry, coconut smallholders, strategic partnership, supply chain, supply chain vertical integration AbstrakTumbuhnya industri pengolahan kelapa di Gorontalo membuka peluang untuk meningkatkan kinerja perkebunan kelapa rakyat yang cenderung menurun, sehingga dapat mendukung kebutuhan bahan baku industri melalui pengembangan rantai pasok yang lebih efektif.

A Randomized Block design consisting of two factors and two replications was applied. The first factor was clones consisting of three lemongrass (C. citratus), i.e., a) Sukamulya, b) Cimande, c) Banten, and d) one clone of C. flexuosus. The second factor was organic fertilizer (1 kg/plant), namely: a) control, b) cow manure, c) goat manure, and d) chicken manure. The results showed that the application of organic fertilizer derived from cow and goat manure could increase the leaf length of several lemongrass clones. Plant growth, including the number of tillers, plant height, leaf length, pseudo-stem length, canopy, oil content, and oil yield of five-months-old citronella plants, were influenced by clones.

The objective of the research was to investigate the possibility used of apical and basal stems as planting materials and to investigate dormancy breaking and stimulating bud growth methods of apical and basal stems. The research was arranged in a completely randomized design with two factors. The first factor was the position of bud setts in a stem (apical, middle, and basal). The second factor was dormancy breaking and growth-promoting solutions (IAA 100 ppm, IAA 200 ppm, GA 3 50 ppm, GA 3 100 ppm, KNO 3 3%, ZA 0.36% for 30 min. and hot water treatment (HWT) 50 0 C for 1 and 2 hours). All the treatments were replicated three times. The result showed that soaking apical bud setts in IAA 100 ppm or water could increase 3 shooted bud setts, whereas basal bud setts soaked in KNO 3 3% or water could increase 1 shooted bud setts. Soaking bud setts from the middle part of the stem in water, ZA 0.36% or KNO 3 3% resulted in 6 shooted bud setts. Bud setts from apical and basal stems could be used as planting materials, which increase the multiplication index to 1:11, higher than the current procedure (1:6). Soaking into the water for 30 minutes recommended for dormancy breaking and stimulating apical and basal bud setts.

Penelitian ini bertujuan mendapatkan informasi potensi pemanfaatan batang atas dan batang bawah tebu sebagai sumber benih dan mendapatkan metode perlakuan benih untuk meningkatkan viabilitas benih yang berasal dari batang atas dan bawah tebu. Rancangan penelitian yaitu Rancangan Acak Lengkap 2 Faktor. Faktor pertama yaitu bagian batang (atas, tengah dan bawah). Faktor kedua adalah pematahan dormansi dan percepatan pertunasan dengan perendaman dalam larutan IAA 100 ppm, IAA 200 ppm, GA 3 50 ppm, GA 3 100 ppm, KNO 3 3%, ZA 0,36% selama 30 menit, hot water treatment (HWT) 50 0 C selama 1 dan 2 jam. Semua perlakuan diulang 3 kali. Perendaman bud setts batang atas dalam larutan IAA 100 ppm atau air menghasilkan tambahan 3 bud setts , sedangkan perendaman bud setts yang berasal dari batang bawah dalam larutan KNO 3 3% atau air menghasilkan tambahan 1 bud setts. Perendaman bud setts yang berasal dari batang tengah dalam air, ZA 0,36% atau KNO 3 3% menghasilkan 6 bud setts . Penggunaan batang atas dan bawah sebagai bahan tanam dapat meningkatkan faktor penangkaran menjadi 1:11 (jika berdasarkan Standar Operasional Prosedur 1:6). Perendaman dengan air selama 30 menit direkomendasikan untuk pematahan dormansi dan percepatan pe","PeriodicalId":17774,"journal":{"name":"Jurnal Penelitian Tanaman Industri","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83609055","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High genetic diversity in generative propagated germplasm collection is a basic foundation to develop new high-yielding varieties. The research aimed to detect the genetic diversity of kemiri sunan population in NTT based on RAPD markers. The study was conducted at the Integrated Laboratory, Balittri, Sukabumi from May to July 2019. A total of 32 kemiri sunan accessions were obtained from a private plantation owned by PT BHLI in Bajawa, Flores, NTT analyzed its genetic diversity using 40 RAPD markers. Markers that produced polymorphic bands were scored in binary data format and were then used for genetic diversity analysis using the NTSYS program. Results showed that 11 RAPD markers were polymorphic and generated a total of 41 bands consisting of 32 polymorphic bands (78.05%) and 9 monomorphic bands (21.95%). The genetic diversity analysis with a genetic similarity value of 0.737 showed that the 32 kemiri sunan accessions were divided into 2 clusters. Among those, two accessions (T2 and T4) can be selected as candidates for new high-yielding varieties, because they are located in different groups and showed high per plant fruit number. The result of the study also obtained the genetic distance value between kemiri sunan accessions varies from 0.00 to 0.46. The combination of two kemiri sunan accessions with a high genetic distance value should be useful as parents to obtain F1 progeny with a high heterosis effect.
