Abstract

DOI: 10.17014/ijog.v8i4.168Kulon Progo Mountain, located west of Yogyakarta, is known as a unique morphological expression of an elongated dome frequently called “oblong dome”. The structural elements occurring in Kulon Progo Mountain were predominated by a radial pattern. Applying a quantitative method to measure various morphometric elements however, revealed that the regional geotectonic pattern apparently controlled the development of Kulon Progo Mountain. A general picture of the tectonics showed that the mountain building of Kulon Progo was not solely predominated by a vertical undation force; instead it was closely related to the general geotectonics operating in the area. The macro morphological analysis using various types of satellite imageries augmented with field visits unraveled three regional tectonic stages controlled the development of Kulon Progo Mountain. Those are Meratus, Sunda, and Java trends, operating in SW-NE, NNW-SSE, and E-W directions respectively.

Abstract

Potensi panas bumi suatu daerah sangat didukung oleh ketersediaan airtanah di daerah tersebut. Penelitian hidrogeologi yang dilakukan di daerah Gedongsongo, Ungaran, Jawa Tengah dan sekitarnya ini dimaksudkan sebagai penelitian geologi permukaan dengan menekankan pengamatan pada batuan dan airtanah. Metode yang dilakukan adalah survei geologi lapangan dilengkapi dengan pengamatan mataair dan sumur penduduk, pengukuran infiltrasi, pengambilan contoh batuan serta airtanah. Potensi airtanah yang bagus ditunjukkan oleh akifer yang cukup permeabel serta banyaknya mataair dan airtanah dangkal ini akan mendukung potensi pamas bumi di Gedongsongo. Akifer di daerah penelitian terdiri dari zona akifer breksi dan lava Ungaran Muda serta akifer breksi volkanik Notopuro. Airtanah pada zona akifer ini disimpan dalam celahan maupun ruang antar butir. Mataair tersebar di banyak tempat di daerah penelitian. Mataair panas dijumpai di Gedongsongo dan merupakan salah satu manifestasi panas bumi. Muka airtanah dangkal semakin rendah ke arah lereng bawah G. Ungaran. Airtanah dangkal pada daerah penelitian ini mengalir radial ke arah barat daya, selatan dan tenggara, mengikuti morfologi G. Ungaran. Kata kunci: , , ,

Abstract

Panasbumi merupakan sumberdaya alam terbarukan, yang dewasa ini semakin dibutuhkan masyarakat guna pemenuhan energi alternatif. Sumberdaya alam ini merupakan sumber energi yang ramah lingkungan dan akan menjadi energi penting di masa depan menggantikan sumberdaya minyak yang semakin menipis cadangannya. Oleh karenanya, potensi panasbumi di daerah Jawa Tengah perlu diketahui sebagai antisipasi kebutuhan energi alternatif di masa depan, selain juga potensi pengembangan daerahnya sebagai situs geowisata. Langkah awal untuk mengenal potensi panasbumi adalah survei geologi panasbumi untuk melakukan inventarisasi daerah prospeknya. Potensi panasbumi ini dapat dikenal dari manifestasinya di permukaan. Beberapa manifestasi panasbumi yang ada di wilayah Provinsi Jawa Tengah telah diidentifikasi melalui beberapa kegiatan pekerjaan. Hasil survei menunjukkan bahwa di daerah Jawa Tengah terdapat sebelas kabupaten yang memiliki sumberdaya panasbumi, yang diperoleh sebagai hasil aktivitas gunungapi. Adapun sistem gunungapi yang menghasilkan panasbumi tersebut adalah G. Ungaran, Dieng, Slamet, Telomoyo, dan Lawu. Selain berpotensi sebagai sumber energi, daerah panasbumi juga berpotensi sebagai lokasi geowisata.

Abstract

DOI: 10.17014/ijog.5.3.265-276Geomorphological mapping has been done at the upstream part of Progo Drainage Area by measuring some geomorphological indexes and level of shallow groundwater level at 196 stations, to investigate connections between geomorphological characteristics and groundwater system in the area. These indexes are valley floor - height ratio (Vf), valley cross section (Vratio o rVr), stream gradient index (SL), and drainage density (Dd). Based on the linear regression analysis, the four indexes show none to very weak correlation to water table at most locations. It means that all width, height, and width of the river valley do not control shallow groundwater level. However, some locations indicate a strong control of elevation to shallow groundwater level. The first case indicates that there is another controlling factor to the shallow groundwater system. Most likely, a deeper aquifer exists at those locations, which does not show up in the second case. All results give a preliminary indication that morphometry can be used to predict groundwater system in the area.

Abstract

Arrowroot (Maranta arundinacea L.) is an important starchy plant which has potential utilization for food,industry and medicine. The study was undertaken to assess the variability in morpho-physiological characters, tuber yield and starch content of 23 arrowroot populations in Garut District, West Java. The result showed some significant differences in morpho-physiological characteristics, tuber yield and starch content. Growth characteristics revealed that Cilawu population recorded the highest values for some characters: high, leaf number, above growth biomass and tuber biomass. Cikajang population showed the highest tuber yield (210.6 g per plant) followed by Cilawu population (134 g per plant). Cikajang and Cilawu populations also provided the highest tuber biomass, 46.6 g and 60.0 g respectively. Cilawu population was a second population producing the highest starch content (26.1 %) after Cibatu population (27 %). The higher heritability coupled with genetic advance revealed for fresh tuber yield indicated that selection on basis of the character may be helpful to improve arrowroot yield. Most of the growth characteristics had not significant correlation indicating that the characteristics are not good indicator for selection. Cilawu, Cikajang and Cibatu populations have good potential to produce the high quality and quantity of tuber for arrowroot cultivation in Garut District.

Abstract

AbstrakPenelitian tentang mataair dilakukan melalui survei geologi airtanah secara langsung di lapangan dengan penekanan pada aspek geomorfologi. Tujuan penelitian adalah  untuk mengetahui karakteristik pengaliran di daerah penelitian. Lokasi penelitian adalah daerah Girimulyo dan sekitarnya, khususnya yang termasuk dalam Kubah Kulon Progo,  yang termasuk dalam Kecamatan Girimulyo, Kabupaten Kulon Progo.  Penelitian ini dilakukan dengan metode survei geomorfologi dengan melakukan pendataan bentang alam yang meliputi lereng, elevasi dan karakteristik mataair secara langsung di lapangan. Hasil survei menunjukkan bahwa beberapa mataair merupakan mataair depresi dimana pemunculannya dikontrol oleh morfologi/topografi, sebagai contoh yaitu mataair Semurup dan Njuboh. Beberapa mataair kontak juga dijumpai di daerah penelitian, dimana mataair jenis ini tidak selalu dikontrol oleh morfologi daerah setempat, walaupun kadang-kadang berada di suatu lereng yang cukup terjal.. Dengan demikian, hubungan lereng dan elevasi tidak selalu signifikan terhadap pemunculan mataair. Kata kunci: geomorfologi, mataair, lereng

Abstract

Salah satu aspek geologi yang perlu dikaji dalam suatu pengembangan panas bumi adalah geomorfologi daerah prospek. Tujuan dari penelitian ini adalah mengkaji morfologi dan karakteristik sungai di daerah lereng selatan Gunung api Ungaran sebagai bagian dari upaya pengembangan lapangan panas bumi. Adapun metose yang dipakai adalah survei geomorfologi di lapangan, meliputi pendataan / deskripsi bentang alam dan kondisi sungai, baik morfologi lembahnya maupun debit alirannya. Bentang alam di daerah lapangan panas bumi Gunung api Ungaran meliputi puncak Gunung api Ungaran hingga lereng gunung membentuk bentang alam bergelombang lemah hingga perbukitan tersayat kuat. Pola pengaliran radier berkembang dari puncak hingga lereng bawah. Di daerah lereng selatan gunung ini, pola tersebut berkembang menjadi paralel, dendritik dan rektanguler. Pola dendritik berkembang pada litologi dengan resistensi yang relatif sama, umumnya memiliki lembah V, dimana erosi vertikal lebih dominan. Pola paralel berkembang pada breksi andesit dan breksi laharik dengan lembah V pula. Sementara itu pola rektanguler berkembang pada breksi andesit dan sisipan lava, dikontrol oleh struktur kekar dengan bentuk lembah sungai V. Sungai di daerah penelitian cukup banyak walaupun kecil-kecil, dengan debit bervariasi pada bagian hulu hingga hilir, berkisar dari 0,02 hingga 3,11 m3/detik.

Abstract

Gedongsongo geothermal prospect area is located in Ungaran, Semarang Regency, Central Java. Various geothermal manifestations appeared in the area, such as warm ground, hot spring, rock alteration and fumaroles. Geothermal phenomena is interesting to study, especially on the geochemistry of soil, to see the relationship with geothermal activity. Objective of this study is to determine geological structure and their relationship with geothermal systems by analysis the appearance of some chemical elements in soil. Method of the study were geological and geochemical field study, accompanied by soil sampling. Value of  CO2 of soil were taken directly in field, while H2O and Hg  (mercury) content were determined in the laboratory. Soil geochemistry testing of research area performed by looking at the levels of CO2, H2O and Hg. These three compound anomalies occur in several places, indicating closures around Gedongsongo area. This indication is interpreted closely related with rim structure formed by faults encircling Gedongsongo area. Key words: : geochemistry, soil, mercury, Gedongsongo
