This research was conducted in Manado with the aim of identifying factors that could potentially cause landslide susceptibility, mapping the distribution of potential landslides, and evaluating the distribution of landslide-based settlements. The materials used in this study are daily rainfall maps, slope maps, geological / rock maps, fault maps, soil solum depth maps, land use maps, infrastructure maps and population density maps on a scale of 1: 75 000. The map used as research material sourced from documentation studies and interpretation of maps of the earth and satellite imagery. Likewise, other data needed to support this research was obtained through documentation studies and field measurements. Each variable is used to determine landslide scaling and weighting vulnerability. The sum of the multiplication scores and weights of each variable is categorized into five classes of landslide susceptibility levels, which are very light, mild, moderate heavy and very heavy. Settlement distribution analysis is carried out by overlapping between landslide maps and settlement maps using geographic information system (GIS) technology with ArcView GIS 3.3 software. The results of the study indicated that there were three factors that triggered landslide susceptibility in Manado that had a significant effect, namely geological / rock constituent factors, fault factors, and depth of soil solum. Other factors both physical and management factors have a weak influence on landslides because they are on slopes <25%. Most (91.57%) of the study area had very low to low landslide susceptibility. Therefore, the distribution of settlements in the study area is generally in areas that are safe from landslides. Only about 46.12 ha or around 1.17% of settlements in Manado are located in high landslide susceptibility areas. Settlements located in areas with high landslide susceptibility are spread across seven sub-districts, which are located in Bunaken, Tuminting, Mapanget, Sinkil, Pal Dua, Wanea and Malalayang Districts.
Peanut is a plant that has an important role in land and has a high selling value. Therefore it is necessary to take appropriate steps to develop peanut cultivation in the Panasen Sub-watershed by knowing the level of land suitability. The problems faced by the community are 1) lack of interest in the community to plant peanuts, 2) land-use change from agricultural land to lodging land 3) land evaluation has never been carried out for peanut plants in the area. The study used a land unit approach supported by soil analysis, plant growth requirements, and matching. The results showed that the research area was classified as suitable for peanut plants with a suitability class S2 (quite suitable) with a total of 4 land units, namely S2rfns (945.41 ha), S2sn (1675.15 ha), S2srn (938.05 ha), S2sn (13.45 ha) and class suitability of S3 (according to marginal) with 2 land units, namely S3s (12.95 ha), S3s (15.67 ha). The limiting factors for suitability class S2 are root media (r), nutrient retention (f), nutrient availability (n) and terrain (s). The limiting factor for suitability class S3 is the field (s). The limiting factor for N1 land suitability is nutrient availability (n), root media (r) and terrain (s). The limiting factors for conformity class N2 are the field (s) and the rooting medium (r).
The Community Service program entitled The Improvement of Bepang Cake Quality Production and Marketing is focused on 4 main activities, namely (1) counseling on institutional strengthening and group members as partners, (2) counseling on dialogue strategies to equalize perceptions, (3) training on management map preparation Bepang cake product development problems, and (4) training on the preparation of a roadmap for the management of problems developing Bepang cake products in order to improve product quality. These activities are aimed at (1) identifying and managing problems related to institutions and partner group members, (2) providing knowledge / insights about common perceptions strategies, in order to reach an agreement between institutional leaders and members regarding the management of institutional problems and members. , as well as improving the quality and marketing of Bepang cakes, (3) providing knowledge / insights to partners on how to manage group problems, in the form of problem management maps, and (4) roadmaps for implementing institutional and member strengthening programs, as well as quality improvement programs. and product marketing to provide clear directions for program implementation, carry out assistance, monitor and evaluate work processes and results. The final goal is to empower members of partner organizations / groups to resume business, improve the quality of production and marketing of Bepang cakes. Specific targets are (1) the spirit of group members' efforts to revive, (2) quality products, (3) varied flavors, (4) attractive packaging, (5) favorable prices, (6) independence and responsibility in doing business. . The method used is the lecture method, participatory method. The results are as follows: Phase I, institutional strengthening of group members (LM3) through counseling activities on management systems, training as a basis for being able to produce outputs as intellectual property rights how to seek innovations to increase the quality of Bepang cake production, including Industrial product design (draft ) so that it is feasible to sell at a higher price and how to independently break through the accessibility of marketing at the national, even global level. The second stage is evaluating the results of work in developing the processing of Cakes Bepang products that are of higher quality and accompanying the search for marketing accessibility. The 3rd stage, improving the quality of Industrial product design technology, so that it is feasible to sell at a higher price and how to independently break through better marketing accessibility at the national and global levels
North Toraja Regency is an area that is prone to landslides with a potential zone of medium to high ground movement, which has resulted in damage to land transportation routes between districts being cut off, damage to buildings, and loss of lives. The focus of this research is to determine the level of vulnerability and map the class of landslide hazards in the North Toraja Regency. This type of research is descriptive qualitative with Geographical Information Systems (GIS) approach and then analyzed by overlay and scoring (weighting). Based on data processing, the study produced a landslide hazard map in North Toraja Regency with five classes of vulnerability, namely: very low area of 58,049 km2 (50%), low area of 118,087 km2 (11.18%), medium area of 256,057 km2 (22.07%), rather high area of 195,872 km2 (16.07%), very high area of 11,972 km2 (1.03 %).
