Abstract

DOI: 10.17014/ijog.v5i2.97A research on sediments estimated to contain biogenic gas at Saronggi coast Sumenep in Madura, East Java, has been done by using the resistivity method and produced 2-D (two dimensional) cross-sectional along four paths. The results of previous measurements indicate that biogenic gas is present within layers of black shale. It is known that the resistivity values of the black shale bearing biogenic gas is between 0.9-1.3 Ohm m. These resistivity values are used as references to determine the black shale layer bearing gas in four resistivity profiles. The depth of the black shale layers are varies: in profile 1 the depth is between 26.3 and 44.6 m, in profile 2 is between 30 and 45 m, in profile 3 is between 44.6 and 64.8 m, and in profile 4 is between 8,75 and 44,6 m.

Abstract

Placer deposits is suggested to be within the paleo channels present in the study area. It can be identified from high resolution single channel seismic profiles. These paleo channels occurred within sequence D and marked by the presence of cut and fill characters on the seismic record. The placer were deposited during the activity of paleo channel in the regression period. Placer deposits are probably derived from igneous and metamorphic rocks of Mesozoic age found around the Meratus Mountain as the source of Recent placer deposits. The sediments composed of quartz and clay minerals such as kaolinite and montmorilonite.Keywords: placer, paleo channel, quartz, clay mineral, South Kalimantan

Abstract

Child’s social behavior and attitudes reflect the child received treatment at home. Mothers was instrumental in monitoring the development of social behavior in preschool children, where preschool is the year – the first yaer of life a child learn to socialize. The purpose of this study is to determine the relationship parent role as a teacher with the development of social behavior in preschool children (4-6 years) in TK AL-IKHLAS Sukoanyar Village Toyorono Hamlet Ngoro District Mojokerto Regency.This study population uses the cross sectional design with analytic coleration approach. The study population was all parent who have preschool children (4-6 years) in TK AL-IKHLAS Sukoanyar Village Toyorono Hamlet Ngoro District Mojokerto Regency as many as 37 people taken to with sampling is 34 people for research to the purposive sampling techniques. Variable research is the role of parents and development of social behavior in preschool children (4-6 years). Data were collected using questionnaires and observation sheet instruments, after the collected data were analyzed using Mann Whitney test. Mann Whitney test result with critical rejection region ? = 0,05 to obtain the probability calculation (p) = 0,009 so 0,009 < 0,05, which means there is a relationship role of parents as teachers with the development of social behavior in preschool children (4-6 years) in TK AL-IKHLAS Sukoanyar Village Toyorono Hamlet Ngoro District Mojokerto Regency. Based on these studies it is known that a child will be able to undergo normal development in a task if the parent always gives the task of continous development of the child.Keyword : role of parents, social behavior

Abstract

Empty fruit bunches (EFB) has not been utilized optimally. EFB can be used as source of solid fuel in the form of briquettes. The calorific value of the EFB is 18.200,975 kJ / kg. The calorific value can be increased by carbonization process that is followed by densification process. Carbonization process aims to minimize the elements forming of the smoke, so the exhaust gas can be cleaner. Densification Process aims to increase the density and simplify the handling process. The calorific value of the combustion products can be enhanced by adding the filler. Crude glycerol is used as the filler, because it has a the calorific value of 25.175,98 kJ / kg which aims to improve the calorific value. The purpose of this research is to utilize EFB and wasting crude glycerol as a source of solid fuel, to learn how is the effect of crude glycerol, particle size, and compression pressure, to determine the influence of calorific value and compressive strength of the briquettes produced. EFB Densification uses a hydraulic press in operating conditions of particle sizes (60, 80, and 100 mesh), the composition of the filler (60:40, 70:30 and 80:20) and a pressing pressure (100.110, and 120 bar). Responses were analyzed, namely the calorific value and compressive strength by using Response Surface Methodology. The Best calorific value is obtained by 28.999,4 kJ / kg at 80 mesh particle size, composition filler 53: 47, and the pressing pressure of 110 bar. While the best compressive strength value is 9,5316 kg / cm2 at 100 mesh particle size, composition filler 60: 40, and the pressing pressure of 120 bar. Process conditions is very influence significantly on the calorific value and compressive strength is the composition of the filler and the pressing pressure.Keywords: Briquettes, Densification, Carbonization, Compressive Strength, Calorific Value, Empty Palm Bunches

Abstract

Penelitian keberadaan gas biogenik di Teluk Lada Kabupaten Pandeglang Provinsi Banten dilakukan dengan metode seismik pantul dangkal saluran tunggal resolusi tinggi. Tujuan penelitian adalah untuk mengetahui potensi gas biogenik. Stratigrafi seismik diinterpretasikan menjadi satuan Tersier yaitu sub-satuan A1 dan A2, satuan Kuarter yaitu sub-satuan B1 dan B2. Berdasarkan hasil interpretasi data seismik, gas biogenik terdapat pada sub-satuan B2 yaitu satuan batuan sedimen berumur Pleistosen Akhir hingga Holosen. Struktur yang berkembang adalah lipatan dan sesar normal yang kemungkinan merupakan representasi kondisi tarikan (tensional regime) di Selat Sunda.

Abstract

Traditional This study examines the governance of Terong Traditional Market in Makassar City, one of South Sulawesi’s largest markets. Employing a qualitative phenomenological approach, the research aims to explore current governance practices, identify determinants influencing governance effectiveness, and propose strategies to enhance market competitiveness. Data were gathered through field observations, in-depth interviews with traders, market managers, and government officials, as well as document analysis. The findings reveal that governance at Terong Market is hindered by fragmented institutional coordination, inadequate infrastructure, weak regulatory enforcement, and limited trader participation. Four critical determinants of effective governance emerged: (1) strategic policy alignment, (2) transparency in financial and operational management, (3) adoption of digital technologies, and (4) multi-stakeholder collaboration.To improve competitiveness, five strategic measures are recommended: revitalization of market infrastructure, digitalization of retribution and service systems, reform of management and human resources, trader empowerment through training and financing access, and inclusive stakeholder forums for participatory governance. Additionally, this study proposes a reconceptualization of the classical POAC (Planning, Organizing, Actuating, Controlling) model—replacing “actuating” with “mediating”—and emphasizes participatory monitoring to strengthen accountability.The study contributes to public administration literature by presenting an adaptive governance model that aligns with the socio-economic dynamics of traditional markets in transition.
