Abstract

The purpose of this research is to determine the growth components and productivity of three corn varieties (Zea mays L.) in response to the frequency of water irrigation. The treatments were arranged in a two-factor factorial design within a Randomized Complete Block Design (RCBD). The first factor was the frequency of water irrigation, consisting of 3 treatment levels: once a day (F1), every 2 days (F2), and every 3 days (F3). The second factor was the variety factor (V), comprising 3 varieties: Bonanza F1, hybrid variety Pertiwi 5, and variety Bisi 18, resulting in 9 treatment combinations. Each treatment was replicated three times, yielding a total of 27 experimental units. The parameters observed in this study included plant height, leaf count, stem diameter, flowering age, cob length, cob diameter, and cob fresh weight. The results of the research indicate that the frequency of water irrigation significantly affects the leaf count at 14 days after sowing (HST), stem diameter, cob length, cob diameter, and cob fresh weight. Meanwhile, the variety factor significantly influences plant height and leaf count at 14 HST and post-flowering, stem diameter, cob diameter, and cob fresh weight. The interaction between the frequency of water irrigation and variety has a significant impact on stem diameter, cob diameter, and cob fresh weight. The best varieties for all frequencies of water irrigation are Pertiwi-5, and varieties tolerant to drought stress are Pertiwi-5 and Bisi-18.

Abstract

In simple terms, geodiversity is defined as the diversity of non-living natural components in the form of lithology, minerals, fossils, structures and landforms in an area that forms the earth's surface which has differences, thus forming diversity. Geodiversity can be an important factor in developing the tourism industry and local community identity by conducting special research in the form of investigating geological heritage and cultural heritage and integrating the results for educational outcomes in education, promotion and tourism infrastructure. Gorontalo Province has many locations that show great geological diversity, but many of them have not been explored, studied, or not yet established for geotourism. The extraordinary geo-diversity together with the deep ecological resources and cultural heritage provides a valuable basis for the development of geotourism and geoparks. Geological research at Dulanga Beach has never been carried out to assess the existing geological features. Research on Dulanga Beach generally only focuses on the tourism promotion sector. The aim of this research is to determine the potential geodiversity potential of Dulanga Beach. The method used in this research is the main method, namely geological observation and geodiversity assessment methods. Based on research results, the Dulanga beach location has 3 geological features in the form of geomorphology, lithology and fossils or paleontology. The results of the geodiversity assessment show that the Dulanga Beach research for the Scientific Assessment aspect is in the Moderate class, the Educational Assessment is in the High class, the Tourism Assessment is in the Moderate class, and the Assessment Degradation (Degradation Value) is included in the High class.

Abstract

This research was conducted at the UPT Land: Archipelago Dry Land Laboratory, Nusa Cendana University, Kupang from February to May 2024. The purpose of this research was to determine the interaction effect of trichocompost fertilizer dose and urea fertilizer dose on the growth and yield of Samhong mustard greens (Brassica juncea L.) and to determine the treatment of trichocompost fertilizer dose and urea fertilizer dose that provides the best growth and yield of Samhong mustard greens (Brassica juncea L.). This research was designed using a Factorial Randomized Group Design (RAK) consisting of two factors, the first factor is the dose factor of trichocompost fertilizer which consists of three treatment levels, namely 0, 90 g/plant, and 180g/plant. The second factor is the urea fertilizer dosage factor with five treatment levels, namely 0; 0.6 g/plant; 1.2 g/plant; 1.8 g/plant; and 2.4 g/plant. As a result, 15 treatment combinations were made in three groups, totaling 45 experimental units. Each experimental unit consisted of 24 plants and 8 plants were used as sample plants, so there were 1080 plants. The results showed that the interaction of trichocompost fertilizer dose treatment had a real effect on the observation variables of plant height, gross wet fresh weight per plot, and net wet fresh weight per plot. The dose of trichocompost fertilizer 180 g/plant and the dose of urea fertilizer 1.2 g/plant gave the best effect on plant height increase of 19.88 cm/30 days after transplanting (DAT). The dose of trichocompost fertilizer 180 g/plant and the dose of urea fertilizer 2.4 g/plant gave the best effect on gross wet fresh weight of 6250.67 g/1,44 m2 and net wet fresh weight of 5570.67 g/1,44 m2

Abstract

One of the natural resources commonly utilized as raw material in industries—particularly for piling foundations, construction base mixtures, and other basic building materials—is igneous rock. The quality of the rock used as a construction material plays a crucial role in determining its suitability for various infrastructure applications. Therefore, specific physical and mechanical properties of the rock must be evaluated to assess its feasibility for construction use (Yuwanto and Araujo, 2020). This study aims to analyze the characteristics and quality of the rock at the research site and assess its suitability based on the classification from the Indonesian Industrial Standard (SII) 0378-80. The methods used include the Geological Strength Index (GSI) and Unconfined Compressive Strength (UCS). Data were obtained from field observations using the scan line method and laboratory testing of rock mechanical properties. The GSI analysis shows that the rocks have Structure Condition Rating (SCR) values of 6, 10, and 7, indicating structural influence ranging from blocky/disturbed to disintegrated conditions. The UCS analysis results show compressive strength values ranging from 233.351 kg/cm² to 1.161 kg/cm². According to the SII 0378-80 classification, these values reflect the varying levels of suitability of the rock for construction purposes.

Abstract

Penelitian ini telah dilaksanakan di lahan Unit Pelaksana Teknis (UPT) Laboratorium Lahan Kering dan di Laboratorium Kimia Tanah, FakultasPertanian, Universitas Nusa Cendana dengan tujuan untuk mengetahui kemampuan zeolite dalam meningkatkan ketersediaan hara N asal pupuk NPK, pertumbuhan dan hasil tanaman jagung di lahan kering beriklim kering di NTT. Penelitian dirancang dalam percobaan faktorial menggunakan rancangan acak lengkap. Faktor pertama yang dicobakan adalah dosis pupuk NPK yang terdiri atas 4 level, yakni: tanpa aplikasi pupuk NPK (P0); 1/3 dosis anjuran pupuk NPK yakni 133,33kg.ha-1 (P1); 2/3 dosis anjuran pupuk NPK yakni 166,67kg.ha-1 (P2); dan sesuai dosis anjuran yakni 400 kg.ha-1 (P3). Faktor kedua yang dicobakan adalah dosis zeolit yang terdiri dari 4 level, yakni: tanpa aplikasi zeolit (Z0); 3t.ha-1zeolit (Z1); 6t.ha-1zeolit (Z2) dan 9t.ha-1 zeolit(Z3). Terdapat 16 kombinasi perlakuan yang dibuat dalam 3 ulangan. Parameter yang diamati adalah: kandungan N-total tanah, tinggi tanaman, total jumlah daun per tanaman dan bobot segar tongkol per tanaman. Hasil penelitianmenunjukkan: (1) peran zeolit dalam meningkatkan ketersediaan N asal pupuk NPK di dalam tanah terlihat hanya pada level perlakuan dosis pupuk NPK yang relatif tinggi. Pada level dosis pupuk NPK sebesar 2/3 dosis anjuran (267,66 kg.ha-1) dan sesuai dosis anjuran (400kg.ha-1), aplikasi zeolit dengan dosis 3 ton.ha-1, 6t.ha-1, dan 9t.ha-1 mampu menghasilkan kandungan N-total tanah yang nyata lebih tinggi dibanding perlakuan tanpa aplikasi zeolit; (2) aplikasi pupuk NPK sebanyak 1/3 dosis anjuran (133,33 kg.ha-1), 2/3 dosis anjuran (267,66 kg.ha-1) dan sesuai dosis anjuran (400kg.ha-1) mampu menghasilkan bobot segar tongkol per tanaman yang nyata lebih tinggi dibanding perlakukan tanpa aplikasi pupuk NPK. Walaupun demikian, antar perlakuan dosis pupuk NPK tidak terdapat perbedaan yang nyata pada bobot segar tongkol yang dihasilkan, sehingga tidak ditemukan perlakuan dosis pupuk NPK yang memberikan pengaruh terbaik terhadap hasil jagung pada penelitian ini; (3) aplikasi zeolit dengan dosis 9t.ha-1memberikan pengaruh yang terbaik terhadap bobot segar tongkol per tanaman jagung dibanding perlakuan dosis zeolit 3t.ha-1 dan 6t.ha-1.

Abstract

Bolaang Mongondow is located on the Eastern North arm of Sulawesi. This area is a Neogene-aged magmatic arc composed of plutonic and volcanic rocks that indicate mineralization-bearing host rocks. The study aimed to determine the geological setting and alteration based on geological observations and geochemical analysis. The method used is geological mapping, followed by laboratory and studio data analysis. The lithology of this area is composed of andesite, diorite, and pyroclastic breccia units. Two main faults are the Northwest-Southeast trending dextral fault and the Northeast-Southwest trending sinistral fault, which causes hydrothermal mineral alteration. Mineral alteration in the study area is divided into several zones, including the Silicification Zone (massive silica + vuggy silica), Advance Argillic Zone (illite + alunite + dickite + halloysite + kaolinite), Argillic Zone (illite + montmorillonite + pyrophyllite), Prophyllitic Zone (chlorite + montmorillonite). The presence of mineral assemblages and alteration zones shows the characteristics of High Sulfide Epithermal deposits with the highest level of 0.47/ppm in the Advance Argillic Zone.
