The conversion of forests to non-forests by communities has resulted in the loss of forest ecosystems and a reductionin the area of land that can be utilized for nature tourism at Menumbing Mountain Grand Forest Park (MMGFP).Revegetation is needed by planting several types of forest vegetation that generate economic benefits for the communityas well as attracting natural tourism in MMGFP utilization block such as durian (Durio zibethinus Murr.) and rambutan(Nephelium lappaceum L.). It is necessary to evaluate utilization block to ensure that both species grow well andproductivity of fruits have optimal yield. This study aims to obtain recommendations for improvements of the land qualityalong with the suitable characteristics to be limiting the growth of durian and rambutan. Suitability evaluation of durianand rambutan refers to the land suitability classification criteria compiled by Indonesian Center for Agricultural LandResources Research and Development by matching the growth requirements of both types with land utilization blockcharacteristics. Durian and rambutan are considered to be marginally suitable (S3) for planting in most land utilizationblock. The limiting factor of durian and rambutan is rooting medium, i.e texture and nutrient retention, comprising pH ororganic carbon (C-organic). The texture of the soil can not be modified because it is permanent. Soil pH can beincreased through liming. The soil C-organic content can be increased through the application of organic fertilizer. Afterboth efforts are made, the planted durian and rambutan are likely to grow well and productivity of the fruit will beoptimal so that revegetation in the utilization block will be successful and problems faced in MMGFP will be solved.Key words: Liming, marginally suitable, organic fertilizer, revegetation

Proposed Model

A field area coverage-planning algorithm has been developed for the optimization and simulation of capacitated field operations such as the organic fertilizer application process. The proposed model provides an optimal coverage plan, which includes the optimal sequence of the visited tracks with a designated application rate. The objective of this paper is to present a novel approach for route planning involving two simultaneous optimization criteria, non-working distance minimization and the optimization of application rates, for the capacitated field operations such as organic fertilizer application to improve the overall operational efficiency. The study and the developed algorithm have shown that it is possible to generate the optimized coverage plan based on the required defined capacity of the distributer. In this case, the capacity of the distributer is not considered a limiting factor for the farmers. To validate this new method, a shallow injection application process was considered, and the results of applying the optimization algorithm were compared with the conventional methods. The results show that the proposed method increase operational efficiency by 19.7%. Furthermore, the applicability of the proposed model in robotic application were demonstrated by way of two defined scenarios.
