Abstract

Desa Simo merupakan salah satu desa di Kecamatan Kradenan, Kabupaten Grobogan, Provinsi Jawa Tengah yang memiliki potensi lokal yaitu pertanian, peternakan, kehutanan, industri mebel, UMKM dan pariwisata. Potensi pariwisata di Desa Simo dapat dikembangkan karena memiliki potensi sumber daya alam (SDA) dan sumber daya manusia (SDM). Kegiatan pengembangan pariwisata bertujuan untuk menumbuhkan usaha pariwisata berbasis potensi lokal di Desa Simo, menumbuhkan kreativitas masyarakat, dan meningkatkan sumber perekonomian masyarakat. Pengembangan pariwisata dilaksanakan melalui dua program yaitu pemanfaatan Pulau Pongol di tengah Waduk Simo yang awalnya terbengkalai menjadi objek wisata Pongol Island dan pembangunan Pasar Kuliner Digdaya dengan memanfaatkan hutan jati dan limbah kayu. Pelaksanaan program melibatkan peran aktif Pemerintah Desa Simo, badan usaha milik desa (BUMDES), kelompok sadar wisata (pokdarwis), pemuda dan ibu rumah tangga pelaku UMKM di Desa Simo. Pengembangan Objek Wisata Pongol Island telah mampu menarik wisatawan untuk berkunjung hingga Desa Simo berhasil ditetapkan menjadi salah satu desa wisata di Kabupaten Grobogan. Pembangunan Pasar Kuliner Digdaya menjadi wadah berkreasi bagi pelaku UMKM kuliner dan seni budaya tradisional sehingga mampu menambah sumber perekonomian masyarakat Desa Simo. Namun perlu adanya upaya keberlanjutan melalui peningkatan sarana prasarana wisata, peningkatan SDM pengelola wisata dan peningkatan publikasi, promosi dan branding wisata sehingga Desa Simo terus berkembang sebagai desa wisata di Kabupaten Grobogan.

Abstract

The quality of crude palm oil (CPO) is influenced by the quality of fresh fruit bunches, crop culture, and postharvest handling. A delay in fruit processing can cause physical damages to the fresh fruit bunches. Gibberellic acid (GA3) can potentially reduce the physical damage due to delayed processing of the fresh fruit bunches. Our study aims to determine how GA3 affects the physical and chemical quality of oil palm fresh fruit bunches. The fresh fruit bunch samples were collected from the IPB-Cargill Palm Oil Education and Research, Jonggol, Bogor, Indonesia. This study used a randomized complete block design that consisted of four concentrations of GA3: 0, 12.5, 25 and 37.5 ppm. GA3 application reduced fruit loss, respiration rate, and maintain fruit moisture and firmness, increased the oil content, and stabilize the free fatty acid content. GA3 concentration of 12.5 ppm is the optimal concentration. Based on the correlation analysis, fruit softness has a strong correlation with free fatty acids.

Abstract

Nanomagnetite was synthesized using water extract of bilimbi (Averrhoa bilimbi). The high citric acid content has the potential as a reducing agent in the synthesis of magnetite using the hydrothermal method. The synthesis was conducted using different sizes of hydrothermal reactors, 50, 150, and 1700 mL. The results showed that a reactor with a volume of 150 mL and a synthesis time of 12 h was the best condition for synthesis. The results obtained from X-ray diffraction analysis showed that in the best conditions, the crystallinity level was 74.4%, the ratio of product to volume was 3.7×10–2 g/mL, the Fe content in magnetite was 22.0%, the Fe content in the remaining liquid was 0.02%, the Fe ratio was 96.9%, and the ammonium content in the solution was 1.24% w/v. The best conditions were 150 mL reactor and 12 hours synthesis.

Abstract

The optode membrane is a membrane that can identify ions in an aqueous solution. One of the most widely used optode membranes is cellulose triacetate based. Cellulose triacetate (CTA) has the characteristics of hydrophobic, transparent, elastic, and affordable. There are sources of cellulose triacetate that can be utilized and waste paper is one of them. Waste paper is extracted to obtain the cellulose, then by acetylization reaction to produce cellulose triacetate. The resultant cellulose triacetate has a degree of substitution (DS) of 2.89 and an acetyl group percentage (% AG) of 43.64. The standard and synthesized CTA optode membrane are tested for performance with various parameters, ie optimum pH, optimum immersion time, working range, limit of detection (LOD), and limit of quantification (LOQ). The standard CTA optode membranes and synthesized worked at pH 3 and 4 with optimum immersion time for 15 min, respectively. The optode produced a linear response in detecting Cr(VI) ion in the concentration range of 0.02-1 mg/L for standard CTA with an R2 of 0.9726 and 1-25 mg/L for synthesized CTA with an R2 of 0.9764, The limit of detection (LOD) and limit of quantitation (LOQ) were 0.0015 mg/L and 0.0051 mg/L for standard CTA, while 0.0224 mg/L and 0.0749 mg/L for synthesis CTA respectively. Since both optode membranes' performance test results are adequate, the synthesis results of CTA optode membranes can be employed as one source of cellulose triacetate.

Abstract

This research made a visual strip sensor to measure the levels of iron. This sensor whose made of paper cellulose acetate that has been coated by polyacrylamide and 1,10-penantroline complex inserted. Visual sensor strip testing is done with various concentrations of iron(II) to create a standard series and see the range of concentrations of iron(II) which can be distinguished by the eye. The stability of the color of sensor that have been tested were observed in 4 days. Visual strip sensor can distinguish the range of 5 ppm and slightly increased after the color intensity observed in four days. Measurement of the blood enhancing drug samples with 3 repetitions producing good. The result of visual strip sensor was compared with AAS and obtained 99.42% accuracy.

Abstract

Free-living N2-fixing bacteria are essential in the soil because they provide a source of nitrogen in the form of ammonium needed by plants to be used in building protein blocks. The fixation of free N2 needs to be increased by adding nanomaterials such as magnetite (Fe3O4), which has an active group and can be a source of nitrogenase enzyme cofactor. In this study, increased N2 fixation used N2-fixing bacteria in Burks medium. This increase was determined by measuring NH3 levels using the Phenate method formed after Burks medium was treated with Fe3O4 and chitosan-magnetite (CS-Fe3O4). The study found that the number of bacteria can be well decreased. This research showed that using Fe3O4 and CS-Fe3O4 increased NH3-N levels in cultures of free-living nitrogen-fixing bacteria by 15.40% and 75.54%. For future development, it can be in the form of optimization, the effect of adding the same material to plant secondary metabolites, and the mechanism of bacteria in using the material.

Abstract

Industri pertanian di Indonesia terus berupaya mengembangkan solusi berkelanjutan, salah satunya dengan penggunaanpupuk organik. Pengelolaan limbah kotoran sapi di Kampung Manglad, Desa Cibodas, Kecamatan Rumpin, Kabupaten Bogor, menjadi salah satu contoh dalam upaya meningkatkan kualitas pertanian melalui program Pemberdayaan Kelompok Masyarakat (PKM) yang didanai Ditjen Dikti Kemdikbudristek. Kelompok Pengolah Limbah (KPL) di Kampung Manglad bekerja sama dengan IPB untuk mengolah kotoran sapi menjadi pupuk organik padat. Program ini dilaksanakan dalam empat tahap, yaitu meningkatkan pemahaman KPL, pelatihan pembuatan pupuk, adopsi teknologi, dan pemasaran produk. Hasil analisis menunjukkan pupuk organik padat yang dihasilkan memenuhi standar kualitas dengan kandungan N, P, dan K yang melebihi batas minimum. Program ini tidak hanya memberikan solusi terhadap masalah lingkungan tetapi juga meningkatkan ekonomi bagi masyarakat sekitar.

Abstract

A common enzyme for superoxide anion radicals biosensors is superoxide dismutase (SOD). Deinococcus radiodurans protein extract can replace the use of pure SOD enzymes for superoxide anion radicals biosensors. The purpose of this research is to determine the analytical performance of the superoxide anion radicals biosensor with protein extract of Deinococcus radiodurans immobilized on carboxymethylcellulose-gelatin-zeolit (CMC-G-Z) that is crosslinked by glutaraldehyde. The response surface method showed that the optimum condition for the biosensor was pH 7, protein extract concentration of 1075 µg/ml, zeolite concentration of 5 mg/ml, and glutaraldehyde concentration of 0.0042 M. Stability of the biosensor retained 67% of its sensitivity after use for 24 hours. The biosensor exhibits good analytical performance with a linear range from 0.1 – 0.8 mM, a detection limit of 77.84 µM, and a limit of quantification of 259.5 µM with a correlation coefficient of 0.9905.
