Pelatihan Budidaya Cabai Rawit untuk Kebutuhan Rumah Tangga di Provinsi Kalimantan Tengah: Training of Cayenne Pepper Cultivation for Household Needs in Central Kalimantan Province
No full textCayenne pepper cultivation training to household needs is a collaboration between the Agrotechnology study program, Faculty of Agriculture, University of Palangka Raya with the Indonesian Phytopathology Association, Regional of Central Kalimantan, which has been carried out from April to December 2024 in the city of Palangka Raya and Bukit Bamba Village. The training was in counseling and also cultivation guidance through field visits for people who received chili seeds. Eighty percent of the plants distributed grew well, where 40% of the fruit could be consumed for household needs, and the cause of the failure of the chili harvest was that the plants were stolen, there were pest and disease attacks, and lack of patience or lack of interest in caring for the plants. The average successful chili harvest production per harvest per tree per week was 39 grams. This activity not only includes the distribution of cayenne pepper seeds, but also has a positive impact on the community. From the data obtained, as many as 82.14% of chili plants grew well, while 17.86% were lost, either due to theft or pest and disease attacks. The first harvest showed that 78.26% of the harvested chilies had been used for household needs, while the remaining 21.74% were still waiting for the harvest period. In terms of production, the average harvest per tree reached 39 grams, with the lowest yield of 18 grams and the highest of 66 grams. This achievement shows the great potential of cayenne pepper cultivation in increasing food security

Analisis Penelitian Rute Transportasi Darat Balikpapan-Samarinda: Analysis Of Land Transportation Route Choice Balikpapan-Samarinda
No full textThe existence of one of the transportation infrastructure in Indonesia, namely the Balikpapan-Samarinda Toll Road, can be traveled by one route through Soekarno-Hatta National Road with a distance of 114 km, while after the realization of the Balikpapan-Samarinda toll road, it can be reached with a distance of 97.99 km with a travel time of only 1 hour 12 minutes and with a tariff of Rp. 146,500 for class 1 (one) vehicles through the Manggar toll gate to Mahkota Bridge 2 (PTJBS, 2021). With the addition of one traffic route from Balikpapan City to Samarinda City or vice versa, of course travelers can choose a travel route that can reduce distance. However, not all passengers choose the same route, many factors can influence the route choice by passengers. This research is conducted by interviewing route users and obtaining travel characteristics and route selection model with attributes of travel cost, and travel time. From the regression results, the travel cost utility equation Ujt - Ujn = 0.00002 (X1) - 3.2886 and the travel time utility equation Ujt - Ujn = 0.0876 (X2) - 2.9795. Both attributes produce a min (-) utility function model, which means that the smaller the difference in travel costs and times, the greater the potential for route users to move from Jl. Nasional to Jl. Tol
Evaluasi Kinerja Dinding Penahan Tanah (Retaining Wall) Pada Proyek Pembangunan Drainase Mendawai: Performance Evaluation Of Retaining Walls On The Mendawai Drainage Development Project
No full textThe issue concerning the retaining wall revolves around the potential risk of landslides triggered by soil displacement, primarily observed in the main drainage channel within Mendawai's trading district. Despite the installation of retaining walls along the channel, persistent issues have led to structural failure or even collapse. In response to this challenge, researchers aim to investigate the impact of retaining wall usage on slope stability in the construction project of drainage channels in Mendawai, Palangka Raya, Central Kalimantan. This study will utilize manual calculation methods alongside analysis using geotechnical software, specifically Plaxis 8.6. Analysis of manual calculations reveals a significant discrepancy in safety factors. Manual calculations yield a slope stability value of 1.463 and a shear stability value of 0.834, both falling below the safety standard of 1.5. Meanwhile, Plaxis 8.6 analysis indicates a retaining wall bearing capacity value of 1.599, also below the safety standard set at 3. This indicates that the retaining wall experiences failure and fails to meet the anticipated safety standards
