GEO-RESOURCES SECTOR 1. MINERAL PROGRAMME

1.1 Summary

In 2007 – 2008, mineral sector remains as one of the most important sectors in empowering Indonesia’s economic growth. This is indicated by ascending its contribution to the country’s income. Mining sector is also becoming the accelerator to its related sectors and providing a large opportunity for direct or indirect manpower supplies. Such condition is supported by world’s mineral and metallic commodities that booming International market and in the same time exploration and investment activities increasing. However, Indonesia has not yet encouraged this challenging situation optimally due to the overlapping conditions in mining industries such as illegal mining (PETI), and un-conducive regional government’s law. To overcome the said-above mentioned constraints, there are some actions to be taken, amongst other: finalizing draft of Coal and Mineral law, synchronizing and harmonizing policy on law related to mining sector particularly of Center and Regional inter-sector governments, increasing local expenditure by utilizing supported products and industries including enhancing the growth of domestics mineral-product manufacturers and facilitating data and information accessibility of mineral resources by collecting primary and secondary data from the existing investigation reports and information disseminations.

1.2 Annual Review of Technical Programmes/Activities

During 2007 – 2008, Center for Geological Resources (CGR) has carried out some

activities to update and to increase data and information of mineral resources, concerning with escalation of its data and information especially nickel, iron ore, manganese, gold, copper and lead. The activities has been conducted in Nanggroe Aceh Darussalam, East Java, East Nusa Tenggara, North Sulawesi, North Maluku and Papua Provinces.

The Center of Geological Resources in 2007 and 2008 has conducted survey of oil shale and oil seeping in Sanggau-Skadau; Nangasilat, Kapua Hulu Regency of West Kalimantan and Kedungjati area, Semarang Regency.

Based on field investigation of Sanggau-Skadau areas, oil shale deposit occurred on Silat shale having age of Late Oligocene with the thickness around 1.65 -> 2.50 m and the dip of 10°- 15°. Hypothetic resources of oil shale about 8.04 million tons by retort analysis showed oil content varied from 10 – 24 l/ton.


From the oil content in rock investigation in Kedungjati area, Semarang Regency of Central Java Province, geochemical evaluation result on rocks sample and oil seeping at this area showed the grade of thermal maturity on sedimentary rocks of Kerek and pelang Formatiions still thermally immature. From GC and GCMs analysis, both Kerek and Pelang Formations confirmed that these Formations were not of host rocks for oil seeping that formed in Bancak area its vicinity. It is believed that Kerek Formation was of faulted cap rock seen from its seeping pattern that flowed to Botorepaking anticline.

Further investigation of oil shale in Nangasilat, Kapua Hulu Regency of West Kalimantan indicated that oil shale thickness occurred in this area was about 20 m up to > 38 m that discovered in Silat Shale, while according to preliminary investigation, oil shale of Nangadakan area showed its oil shale thickness of > 10 m.

2.2 Geothermal 2.2.1 Summary

Indonesia is one of the richest countries in term of geothermal energy resources. At

least 27 GWe geothermal energy resources are distributed along the Indonesian volcanic belts. However, the production is only 1042 MWe or about 3 % of the total energy potential. Currently, the geothermal energy is mainly used for electricity, but only some for commercially direct used.

A larger part of geothermal areas in Indonesia (60%) are still in the stage of preliminary survey. These areas need to increase status of survey by government, company or collaboration with other country. Particularly those are of small scale and situated in remote islands, the government have to involve more in developing this kind of resources.


As mandated by Indonesia Geothermal law No, 27/2003, the Center of Geological Resources, Geological Agency, Department of Energy and Mineral Resources conducts geothermal survey around Indonesia, including inventory and exploration. The results are 256 geothermal areas identified and total energy potential of about 27601 MWe. These include 8735 MWe of Speculative Resources, 4393 MWe of Hypothetical Resources, 11135 MWe of Possible Reserve, 1050 Probable Reserve and 2288 MWe of Proven Reserve. From this, nine areas have been issued by the Government as new working areas and ready to be tendered. These area include Seulawah Agam (NAD), Jaboi (NAD), Tampomas (West Java), Cisolok Cisukarame (West Java), Tangkuban Parahu (west Java), Ungaran (Central Java), Ngebel Wilis (East Java), and Jailolo (North Maluku), Sokoria (East Nusa Tenggara).

The Center of Geological Resources is carrying out Geothermal Exploration drilling in

Sokoria Geothermal Field, East Nusa Tenggara during FY 2007. The GA is also in conducting steam testing and gathering for Mataloko geothermal wells in preparing a small scale (2.5 MWe) geothermal development Flores Island of Eastern part of Indonesia. Involving the government in such geothermal exploration is, at least, to reduce risk investor.


To accelerate geothermal development in Indonesia as guided by the Indonesia geothermal roadmap 2005 – 2025, and preparing the World Geothermal Congress 2010, the Geological Agency conducted the Indonesian Geothermal Workshop on Resources and Utilization in Conjunction with OC – SC Meeting of the World Geothermal Congress 2010 on 28 - 30 April 2008 in Bali. The Geological Agency has also joint cooperation with Japan government (JICA) in master plan study of geothermal development in Indonesia during the fiscal year 2006 and 2007.

carried out by Marine Geological Research and Development Center. This project are coincided with the Planning and Development of Local Government especially along the coastal line and its surroundings and also for mineral resources development along the coastal zone. The main results of the project activities are as follows:

4.2.1 Cihara and Bayah Coasts, West Java

Bathymetric survey of the study area shows relatively flat with depth 5 meters to 40 meters. Mangrove can be found along the coast of Cihara its make like a wave protection. The bathymetric contours of Bayah coast shown to follow the coastline and change drastically to become shallow at the center until 6 meters. Results from Seismic reflection interpretation shown that morphology like intrusion. The others indications were shown by similar reflector to the east of the study area its also to be interpreted as a intrusions.

Results of coastal characteristic mapping in the survey area can be divided into two

type such as: type 1, characterized by Cliff with high relief found at Cihara coast. Geologically rocks of the cliff is a volcanic rocks. Type 2, characterized by sand wich found along the coast of Bayah.

Surficial sediments from 42 samples have been analyzed and can de divided into 4

types such as sand, sandy silt, silty sand and gravelly sand. Sand distributed along the coast of the study area, silty sand distributed from the depth of 16 m to 37 meters. Gravelly sand found locally at the dept of 37 meters at the south of the study area close to sandy silt which are distributed at the western part.


Coastal process in this area is characterized by high wave energy along the coast of Cihara and Bayah coast. Based coastal characterized mapping can be divided into 2 parts such as Sandy coast and cliff and rocky coast. Sandy coast can be found along the coast of Bayah and in the mouth of Cimadur river. Cliff and rocky coast can be found along the coast of Cihara. Its consist of igneous rock and limestone which are spread along the coast.

4.2.2 Marore and Miangas Islands, North Sulawesi.

The aim of the study area is to know the potential of energy and mineral resources, coastal process and characteristic of the small islands in Indonesian border.

The bathymetric data of Marore island show that the western morphology is very deep

until 110 m close to the island but in the eastern part is gradually to 90 m from coastline to 3 km long to the shore but in Miangas island the morphology show that very step in the western part and gradually gently slope in the northern part. Coastal process and characteristics of Marore and Miangas islands can be divided into 3 parts such as: sandy coast; rocky and sandy coast; and cliff coast. Sandy coast can be found in the southern part of Marore island and southwest and south of Miangas island. The color of sands are brown to white with size from fine grain and gravel. Sands are dominantly by biogenic from limestone and also from igneous rocks. Rocky and sandy coast can be found in the eastern part of Marore. Generally the source of sand and rock in this area are from limestone and igneous rock. Abrasion in this area is very strong until in the some part of cliff are fall and sliding to the sea. Cliff coast can be found only in the some small places in the northern part of the island and consists of igneous rocks. Surface sediments in Marore and Miangas islands consist of biogenic sand and fragment of shells. Generally the study area consist of mineral of Au, Ag, Mn, Pb, Sr and Li, Ni Cr, Zn and Cu, but the content is not high.

4.2.3 Singkawang Coasts, West Kalimantan.

The coastal process and characteristics of the Singkawang coast can be recognized

such as abrasion coast, cliff coast, muddy coast and sandy coast. The abrasion coast can be found in some part of Tg Merah and Sedau. Muddy coast can be found along the coast of Semalagi until Sedau villages and also in Sawah Bay. Mangrove is dominant in this coastal characteristic, its act as a beach protection from wave destruction to the beach. Sandy coast can be found in Tg Merah, Sedau coast and Suak bay. Sand content silica reef fragment and also material from igneous rock. Cliff morphology can be found in tg Bajau, Tg Belat, Tg Kiat and Tg Banjar in the eastern part of the area, its consist of igneous rock.The Surficial sediment of the Singkawang have been analyzed from the sample of sea bottom and can be divided into 5 types of sediments such as: Silt; sandy silt; silty sand; sand and gravelly sand. Bathymetric survey of Singkawang shows that the deepest part of study area located between the islands Penata Besar and Seluawas with deep 36 m and become deeper to the island Lemukutan and Penata Besar island where is 52 meter and a morphology channel. This morphology controlled by structural development which are can be interpreted from seismic line.

The Karst Museum is located in the center of well-developed karstic area of the

Gunung Sewu (Thousand Hills) Karst Area. The three-storey museum building will be consisting of exhibition rooms, a theatre, and other supporting facilities.

The aim of the project is to introduce and socialize the karst phenomena and its benefits to public. The museum and its surroundings can be used as a tourism object and karst-related scientific laboratory.

The construction of main building will cost about US$ 1.2 million. a. Geoheritage Book Project

The CCOP Geoheritage Book is attributed to the International Years of Planet Earth (IYPE) global environmental campaign to save the earth from worsen environmental degradation and widespread destruction of geosites, geotope, and geoheritage due to anthropogenic activities. The publication CCOP Geoheritage Book is scheduled to be launched on the 51st Steering Committee Meeting on November 2008 in Khon Khaen, Thailand.

The first National Coordinator meeting for CCOP Geoheritage Book was held on 18-19 July 2007 at the Institute for Environment and Development (LESTARI) of the University Kebangsaan Malaysia (UKM), Kuala Lumpur, Malaysia. The informal coordination meeting of the book had subsequently been carried out during the First Regional Conference on Asia Pacific Geoparks and Business Dialogue on 13-15 November 2007 at Langkawi, Malaysia. Apart from that, an informal coordination with an Editor, Prof. Dr. Shafeea Leman from the Universiti Kebangsaan Malaysia Lestari, had also been done during the Fourth Cheongwoon International Symposium on 20-22 September 2008 held at Gyeryongsan Natural History Museum, Daejeon, South Korea. Most of suggestion and correction from Editor had been accommodated and the final draft had been resubmitted to the publisher.


Being a country with many spectacular geoheritage potential spreading throughout its region, selection of geoheritage sites to be designated for the CCOP Geoheritage Book was based on criteria as proposed on the meeting, including heritage value rank (regional, national, global), size, and fragility of the geoheritage sites. Geological information concerning the geoheritage sites was written on popular way with appropriate simplification to avoid complexity. Using these criteria, Indonesia’s contribution to CCOP Geoheritage Book had been submitted according to timetable. The submitted Indonesian Geoheritage sites consists of 26 pages of A4 size files written on Corel Draw X3 Graphic format, including Preface (1 page), Geoheritage Distribution Map of Indonesia (1 page), and information of Indonesian Geoheritage sites (24 pages). b) Database

Geological Agency of Indonesia is consistently pursuing the development of its databases using website technology application. Owing to rapid development on information technology, upgrading the system and migrating the database into currently acceptable format should be prioritized.

First workshop of CCOP Metadata Project Phase II was held on 17-21 March 2008 at Hainan, China. Objectives of the workshop was aimed to compile all ISO-related geoscientific metadata to be developed further into standardize and comprehensive CCOP geoinformation metadata. The most important result of this workshop was the agreement for building up database which will display geoscientific metadata of all member countries.
