Batak Toba Ethnic in Indonesia as a Locus Theologicus: Exploring the Spiritual, Wisdom and Aesthetic Values of Ragi Idup Ulos

Batak Toba is one of many ethnic groups in Indonesia that reside around Lake Toba and are now scattered worldwide. Since the colonial period, this group has become a target for Protestant Christian missions and Catholics, who make it a “locus theologicus” based on their respective characteristics. One tradition of Batak Toba is ulos, such as “ragi idup”, which holds religious, wisdom, and aesthetic meanings. This study examines “ragi idup” ulos as a “locus theologicus” through its spiritual values rooted in wisdom and civilization. The meaning to be achieved in this paper is that the wearing and giving of ulos “ragi idup” is the warning and giving of wisdom in life. Qualitative methods and interviews with knowledgeable individuals help identify religious and wisdom values that can bring theology together using a symbolic approach.

Application of UAV for Village Mapping in Pangambatan, Sumatra Utara

Pangambatan Village, as part of the Lake Toba National Strategic Area and a tourist destination, still lacks facilities, infrastructure, and professional human resources to manage its cultural and tourism potential. An initial mapping of the conditions and potential of the area is needed to drive tourism in Pangambatan Village towards sustainable tourism. This can be done by mapping environmental conditions and tourism potential in Pangambatan Village, providing recommendations for sustainable tourism management, and providing environmental management facilities. The study was carried out using Unmanned Aerial Vehicle (UAV) technology. UAV technology offers new opportunities for fast and efficient remote environmental monitoring and the collection of high spatial and temporal resolution data. The benefits of this mapping can be used to see environmental conditions and environmental pollution that may occur because of tourist activities. In addition, the use of this technology is expected to help related parties in making decisions and planning.

ESTIMASI POTENSI PRODUKSI IKAN DI DANAU SINGKARAK SUMATERA BARAT BERDASARKAN NILAI KLOROFIL-A DAN KELIMPAHAN FITOPLANKTON

The diversity of fish in marine waters is more than in lakes. However, the lake also has high fishery potential, one of which is Singkarak Lake, Solok Regency. On the island of Sumatra, the first largest lake is Lake Toba, while the second is Lake Singkarak. On the one hand, there are several human activities around the lake that cause a decrease in the production of fish catches, such as fishermen who often catch fish with tools that are not environmentally friendly, are not selective and lead to overfishing. Therefore, the purpose of this research is to examine the potential for fish production in Lake Singkarak based on the value of chlorophyll-a and abundance of phytoplankton. The method used is a survey method. The data analysis process includes analysis of fish production potential on the value of chlorophyll-a and analysis of fish production potential on phytoplankton abundance. Based on the chlorophyll-a value, the estimated fish production potential in Singkarak Lake is 4,663 tons/year and based on the abundance of phytoplankton, the fish production potential is 21,852 tons/year.

Domestic Tourist Interest in Lake Toba Tourism Area Destinations

The tourism area around Lake Toba is part of the Indonesian government's super-priority destination program. The goal of this study was to figure out where each destination was on the respondent's mind map. Purposive sampling was used to select 103 participants for this investigation.

A Slab Window Beneath North Sumatra Revealed by P‐Wave Mantle Tomography

AbstractPassive seismic studies have suggested that slab tearing occurs beneath North Sumatra, albeit the slab morphology is somewhat poorly constrained. The lack of resolution on the slab means that the presence of a tear has not been validated, and that the main factors responsible for slab tearing are hard to discern. We use a large seismic data set to determine a new 3‐D high‐resolution tomographic model of the crust and upper mantle beneath North Sumatra, which reveals a well‐defined low‐velocity channel that cuts across the subducting slab through a cavity. This feature cannot be reconciled with a tear in the slab, as previously suggested. Our relocated earthquakes exhibit a protruding cluster of seismicity along the subducted Investigator Fracture Zone, indicating that the high reliefs of the Investigator Fracture Zone possibly enhance the coupling between the subducted slab and the overriding plate. Shear stress resulting from the differential coupling in the slab may have created an area of mechanical weakness in correspondence of the fossil‐spreading ridges, which eventually led to the formation of a slab window. This window allows the exchange of mantle material from the subslab region up to the Toba volcano. We propose that the previously damaged parts (e.g., fracture zones and spreading centers) of the oceanic plate could help promote the growth of a slab window.

Correlation of Macrozoobenthos Diversity Index with Physico-Chemical Factors in Lake Toba, Toba Samosir Regency

Umpasa and Umpama in Batak Toba Culture as A Means of Catechism in Medan Catholic Churches

This article explores Umpasa and umpama of Batak Toba culture as a means of catechesim within Chatolic curches. The work uses qualitative methods with observation, interview and documentation. Descriptive analysis technique is employed based on the triangulation results of techniques and sources. The study targeted 20 adults, 3 Batak Toba cultural practitioners, and 2 priests and bishops who were on the island of Samosir Lake Toba. The work suggests that churches that live and develop today are based on tradition. Tradition is meant to include everything (such as customs, beliefs, habits, teachings, and so on) that is downwardly inhereited. One of the traditions of Batak Toba that is still preserved to this day is umpasa and umpama. This tradition is considered wise because it is used for prayers, petitioning God, and giving advices. Umpasa or umpa has always been used in the teaching of the Medan Catholic Church to the community of Batak Toba in Samosir and its surroundings and has truly become a model of church catechesis, not only by the society of Batak Toba but also as a model for catechism. The work is based on church studies within the Archdiocese of Medan.

Tectonic Structure of Northern Sumatra Region Based on Seismic Tomography of P and S Wave Velocity

The tectonic setting of Sumatra Island is strongly influenced by the oblique subduction of the Indo-Australian Plate, which subducts the Eurasian Plate at a speed of 52–60 mm/year. The movement of these plates resulted in the Northern Sumatra region having seismic sources from tectonic and volcanic activity. The data used in this study is in the form of seismic wave travel-time recorded by numerous seismic stations in the research area from January 2012 to December 2020. The data comes from 5,003 earthquakes recorded by the BMKG seismic network. The inversion is a simultaneous inversion between seismic velocity models (Vp and Vs) and hypocenter parameters by applying a double-difference seismic tomography algorithm. Tomogram results in parts of Aceh (Singkil and Subulussalam) and North Sumatra (Pakpak Bharat and Dairi) at a depth of 0 km show negative perturbations in Vp and Vs values and high Vp/Vs values. The anomaly is most likely related to cracks in fluid-saturated rocks. The tomograms in the south of Lake Toba at depths of 30 km and 40 km have high Vp and Vs perturbation values and low Vp/Vs values. This anomaly indicates a magma supply line that is no longer active or has cooled for a long time. Based on the seismic tomography modeling results, the subducted Indo-Australian Plate to the Eurasian Plate is visible in the study area.

The Impact of Floating Craft Cultivation on the Ecosystem of Lake Toba

Rebranding Samosir Island As City of Foreign Tourists

Tourism contributes greatly to a developing country as one of the driving sectors of the economy. The government and the management of tourist destinations must consistently improve the quality of tourism in terms of destinations, industries, institutions, and marketing because of the scope of tourism and the movement of millions of people on indirect tourist trips. So far, foreign tourists have become familiar with tourist destinations in Bali and Lombok. However, many tourist destinations in Indonesia have not been maximally introduced, like Samosir Island at Lake Toba Region. In 2016, the Government of Indonesia envisioned making Toba become the Monaco of Asia. This article examines the factors affecting how long visitors from other countries remain when vacationing in Samosir, a popular international travel destination in Indonesia. Using 100 hundred samples of international travelers' empirical modeling is carried out using a quantitative approach through Ordinary Least Squares (OLS) and descriptive analysis. The quality of the accommodations, infrastructure, and rising travel costs contribute to longer travel time for tourists. Although it does not considerably shorten the length of stay in Samosir, rising vacation expenditures in other locations are a bonus for adventurous foreign tourists in Indonesia. Although the appeal of nature and its peace appeal to visitors from abroad, income levels do not greatly raise demand for international visitors to Samosir. As an effort, brand management is needed to improve the image of Samosir Island as the city of foreign tourists in Indonesia.
