Abstract

“Mulu bebe” banana (Musa acuminata) is one of the tropical fruit commodities that has the potential in Indonesia, specifically the North Halmahera region has a very high opportunity as a food diversification material. The aim of the study was to determine the chemical composition of "mulu bebe" banana flour produced through the modification of spontaneous fermentation and cooling heating as a prebiotic food source. This study using factorial Randomized Complete Design (CRD) with three replications. The first factor was the duration of spontaneous fermentation of 0, 12, 24 and 36 hours and the second factor was the length of heating, namely 0 and 45 minutes then continued with cooling at 4oC for 24 hours. The results of the chemical composition analysis of “mulu bebe” banana flour with spontaneous fermentation conservation and safety supplements against the chemical composition of banana flour produced were 7.21-10.68% water content, 1.84-2.74% ash content, crude fiber 0, 57 -2.61%, fat content from 0.93-1.44%, protein content from 3.55 to 4.21%, content from 45.63 to 69.24%. Changes in the chemical composition of the banana flour, caused by the fermentation process and the addition of supplements to sliced bananas before drying. This study obtained banana flour products which are low in fat, protein and carbohydrate content which indicated that the bebe banana flour products produced by contained resistant starch (RS) as prebiotic food source.

Abstract

Setiap tahun produksi plastik meningkat secara eksponensial, karena kebutuhannya sangat diperlukan oleh manusia. Tapi plastik berbeda dengan limbah yang lain, disebabkan oleh proses penguraiannya. Guna mengurangi populasi limbah plastik, kegiatan pengabdian kepada masyarakat di desa Wari Ino menitik beratkan pada sosialisasi masalah limbah plastik dan teknik pengolahan. Adapun hasil kegiatan menunjukan perubahan pengetahuan akan bahaya limbah plastik dan penerapan teknologi tepat guna menggunakan sistem pirolisis mampu menghasilkan BBM (Bahan Bakar Minyak) dari plastik jenis HDPE (High Density Polyethylene). Tapi teknologi tersebut masih bersifat prototipe, dan memerlukan pengembangan sehingga dapat dipakai serta diakui oleh seluruh masyarakat secara luas.

Abstract

The Naniura NRD300 HF tool has been used in research using the Wenner-Schlumberger configuration geoelectric method to determine the direction of iron sand distribution, the volume of iron sand, and the concentration of iron sand in the Gura beach area. The collected measurement results are then processed by the RES2DINV software into a 2 Dimension (2D) cross-section that shows the distribution values of the subsurface layer as shown by a color image. Once saved in (.xyz) format, the RES2DINV software results are processed in RockWork software to create pseudo-3D cross sections. The RES2DINV software's results show that line 1's resistivity value ranges from 39.6 to 1000 Ωm, whereas line 2's resistivity value ranges from 0.16 to 1.7 Ωm. These findings suggest that line 2 has a lower resistivity value than line 1 does. The volume of iron sand processed by RockWork software is 221,000 cubic meters for linek 2 and 273,000 cubic meters for line 1. The distribution of iron sand deposits in the study region is south to north, based on the volume of iron sand in line 1, which is bigger. A method used to determine the composition of the minerals present in a sample is called X-ray fluorescence (XRF). The results of analyzing the Fe content in line 2 are 55.01%, which is higher when compared to the Fe content in line 1, which is 40.5%.

Abstract

Research on seawater intrusion has been carried out on the southern Tolonuo island, Tobelo sub-district, North Halmahera Regency, Indonesia using the Wenner-Schlumberger configuration resistivity geoelectric method supported by the Naniura NRD 300 HF tool, this study aims to determine the distribution pattern of seawater intrusion and to determine the resistivity value of each subsurface rock layer in the study area. The measurement results are processed using the RES2DINV software to obtain a 2-D pseudo resistivity section that describes the distribution value of the layer that the soil surface is shown in color images. The measurement results on line 1 show that there is seawater intrusion with a resistivity value range of 0.338 m - 2.44 m which is at 4 – 20 meters with a certain pattern, line 2 also has sea water intrusion at a depth of 5 m – 20 m with a resistivity value of 1.31 Ωm – 6.50 Ωm. On line 3, it is clear that there is a good correlation between the intersection of line 1 and line 2, where there is a low resistivity contrast on the line 1 with a stretch of 35 m – 50 m at a depth of 10 m – 20 m and the line 2 with a span of 80 m - 100 m at a depth of 10 m - 20 m. The distribution pattern of seawater intrusion from the south to the north of Tolonou Village with a wide range of up to 200 meters from residential areas from the shoreline. The research area has layers of clay rock with a resistivity value between 30 – 80 Ωm, and breccia rocks around it with a resistivity value of 100 – 200 Ωm. On the other hand, between clay and breccia there is impermeable rock which is thought to be conglomerate rock with a resistivity value of 200-500 Ωm, besides that in the study area there is also a layer suspected to be a groundwater aquifer layer with a resistivity value (ρ) < 10 m.

Abstract

Water plays an important role in human life, and one of the water resources that can be a source of clean water is groundwater or what is also called a spring. Therefore, the spring in Galao Village, North Loloda District, North Halmahera Regency, needs to be maintained and cared for. In this study, researchers tested water content using several parameters, namely hardness, TDS (Total Dissolved Solids), DHL (Electrical Conductivity), turbidity, and pH. The results of sample testing carried out in two laboratories showed a turbidity of 1.00 NTU and a pH of 7.145 which were tested at the North Halmahera Regency Environmental Service Laboratory. Meanwhile, the main parameters of hardness were recorded at 231 mg/l, TDS 391 mg/l, and DHL 521 μS/cm which were tested at the Manado Industrial Standardization and Service Center (BSPJI) Laboratory. Physically, the three main parameters, namely hardness, TDS and DHL are interrelated; Hardness is caused by contact between water and limestone in the soil layer through which water passes, allowing calcium (Ca) and magnesium (Mg) to dissolve into it. In line with the cause of the presence of dissolved substances caused by weathering, dissolution of rocks and soil and other organic and inorganic substances dissolved in water, there is a relationship between Electrical Conductiv ity (ECP) and the ions contained therein, ions in water come from dissolved salts of alkali compounds, chloride sulfide dissolved in water. The purpose of this study is to determine the content of Hardness, Total Dissolved Solids (TDS), Electrical Conductivity (DHL), Turbidity, and pH contained in water.

Abstract

This research uses the Naniura NRD300 HF tool to apply the Wenner-Schlumberger configuration geoelectric method which aims to determine the direction of distribution of iron sand, the volume of iron sand, and the Fe2O3 concentration of iron sand in the southern Paca beach area. The collected measurement results are then processed by RES2DINV software into a 2 Dimensional (2D) cross section which shows the distribution value of the subsurface layer as shown by a color image. After being saved in (.xyz) format, the RES2DINV software results are processed in RockWork software to create a pseudo-3D cross section. The RES2DINV software results show a resistivity value between 0,0761 – 3,59 Ωm which is identified as iron sand with a volume of 13,304 m3 at a depth of 2,50 – 9 meters from the surface of the datum point, while on track 2, the resistivity value ranges between 0,414 – 3,13 Ωm, and at a depth of 2,50 – 7 meters from the surface of the datum point with a volume reaching 12,883 m3 based on the results of the RockWork software. The distribution of iron sand deposits in the study area is from south to north. The method used to determine the composition of minerals present in a sample is called X-ray fluorescence (XRF). The results of the analysis of the Fe2O3 content in the first pass were 36,704% and in pass 2 it was 35,500%.
