Abstract

Energy auditing is a method of increasing energy efficiency. An energy audit is conducted to provide an overview of energy use, analyze the electrical system, and determine potential cost savings. The laboratory of the national food and drug agency (BPOM) in Manokwari has problems with electricity that often cause interruptions, power outages, and expensive bills. Therefore, this research was conducted to audit the energy used in the laboratory of the BPOM of Manokwari, with a building area of 1,484 m2 and an installed power of 105 kVA. In this laboratory building, a diesel generator with capacity of 5 kVA is installed as a backup energy source and the generator has its own installation line. According to the calculation results before auditing, the energy consumption intensity (IKE) value obtained per month is 10.18 kWh. Energy audit through lighting loads and air conditioning systems. Then the recommendation through energy savings for lights and air conditioners is 274.12 kWh/month and 639.32 kWh/month, respectively. Therefore, total savings are 913.44 kWh/month, or about IDR 1,541,886.72/month.

Abstract

The red fruit (Pandanus conoideus) is an endemic plant from Papua, known for its distinctive color and shape. This fruit is recognized for its bioactive properties, such as antioxidant, anti-inflammatory, and antihyperglycemic effects. Its high pigment content is believed to have potential as a sensitizer in DSSC applications. However, research on this topic remains underexplored. Therefore, the aim of this preliminary study is to investigate the potential of red fruit pigments for DSSC. The characterization of red fruit pigments was conducted through phytochemical screening, FTIR and UV-Vis spectral analysis, as well as literature reviews. Pigment extraction was carried out using maceration without involving drying or grinding processes. Phytochemical screening results revealed that the macerate contains flavonoids, alkaloids, phenolics and terpenoids, compounds commonly used as natural pigments in DSSCs. FTIR analysis showed the presence of functional groups such as carboxyl (-COOH), carbonyl (C=O), and hydroxyl (-OH), which can act as effective anchoring groups when interacting with nanosemiconductor surfaces. Meanwhile, UV-Vis analysis showed absorption peaks in the UV region (wavelength 204–399 nm) and the visible region (wavelength 400–550 nm). Based on literature studies and research findings, it can be concluded that the pigments in red fruit have potential applications as DSSC sensitizers.

Abstract

Algae are marine plants that have the potential as raw material for producing biofuel (biodiesel, bioethanol and biogas) apart from being used as biomass. The high lipid content in algae can be converted into biofuel through esterification and transesterification chemical reactions. Research on the chemical composition of algae species found in West Papua remains limited. One type of algae commonly found in the waters of West Papua, especially on the northern coast of Manokwari is Sargassum binderi. Therefore, the aim of this study is to identify the types and percentages of lipid compounds contained in S. binderi. Lipid compounds were extracted using 2 different extraction methods, the maceration method and the Bligh Dyer method. The extraction process uses wet samples of S. binderi without drying, grinding or heating treatments. The type and percentage of lipids were determined via GC-MS analysis. The study results revealed six lipid compounds obtained from the maceration method: tetradecanoic acid (1.4%), 10-octadecenoic acid (4.69%), hexadecanoic acid (19.15%), 9-octadecenoic acid (Z) (5.93%), octadecanoic acid (2.71%), and 5,8,11,14-eicosatetraenoic acid (1.01%), with a total lipid compound percentage of 34.89%. Meanwhile, from the Bligh Dyer method, five lipid compounds were identified: 9-octadecenoic acid (Z) (4.33%), hexadecanoic acid (46.07%), 9,12-hexadecadienoic acid (5.23%), 11-octadecenoic acid (27.18%), and 5,8,11,14-eicosatetraenoic acid (2.81%), with a relatively high total lipid percentage of 85.62%. Hexadecanoic acid, also known as palmitic acid, was the lipid compound with the highest percentage found in both extraction methods.

Abstract

Penelitian ini bertujuan untuk mempelajari hubungan matematis antara berat rendemen ekstrak dan volume maserat. Persamaan matematis ini berguna untuk memprediksi berat rendemen (variabel dependen) dari data volume maserat (variabel independen) ketika alat rotary evaporator laboratorium tidak dapat digunakan karena mengalami kerusakan. Metode analisis yang digunakan dalam penelitian ini adalah regresi linear sederhana untuk menentukan model         persamaan regresi yang menyatakan korelasi antar kedua variabel, menghitung variansi galat acak, menguji hipotesis (uji model adequacy, uji F dan uji intercept) serta menghitung koefisien determinasi adjusted. Berdasarkan penelitian terhadap sampel uji kulit buah matoa, diperoleh model persamaan regresi y = 0,0200x  dengan variansi galat acak, s2 = 0,000160 dan koefisien determinasi adjusted, Ra2 = 96,12%. Sehingga untuk 250 mL volume maserat kulit buah matoa, diprediksi memiliki berat rendemen ekstrak sebesar 4,94 g.
