Abstract

Limbah foil blister obat merupakan salah satu bahan yang umumnya hanya menjadi sampah bagi masyarakat, padahal limbah aluminium jika berada bebas di lingkungan membutuhkan waktu lebih dari 100 tahun agar dapat terurai. Pemanfaatan kandungan aluminium dalam limbah blister obat menjadi aluminium sulfat merupakan salah satu alternatif dalam pengelolaan sampah anorganik. Penelitian ini bertujuan untuk mengetahui konsentrasi pelarut KOH optimal pada sintesis aluminium sulfat dari limbah foil blister obat berdasarkan karakteristik yang dihasilkan. Karakterisasi bahan baku limbah foil blister obat dilakukan dengan menggunakan instrumentasi Atomic Absorption Spectrophotometry (AAS) dan menghasilkan kadar Al sebesar 56,67%. Sintesis aluminium sulfat dilakukan melalui proses preparasi bahan baku, proses pelarutan dengan larutan KOH, proses ekstraksi menggunakan H2SO4, proses kristalisasi dan pengeringan. Pada penelitian ini digunakan konsentrasi larutan KOH 20%, 30%, 40% dan larutan H2SO4 6M. Hasil sintesis aluminium sulfat dikarakterisasi menggunakan Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX). Hasil analisa data menunjukan bahwa aluminium sulfat terbaik diperoleh pada konsentrasi KOH 20% dengan nilai parameter pH, bagian tidak larut dalam air, Fe, Pb dan As telah memenuhi syarat mutu berdasarkan SNI 0032:2011 tentang Aluminium Sulfat. Sedangkan untuk parameter kadar Al2O3 didapatkan hasil sebesar 15,65% dan belum mencapai nilai yang dipersyaratkan yaitu sebesar 17%. Medicine blister foil waste is a material that often becomes waste for the community, therewere aluminium waste if it is free in the environment takes more than 100 years to decompose.

Abstract

Indonesia is a country with the highest biodiversity, especially in mangrove ecosystems, with a total of around 89 species. The mangrove ecosystem includes Rhizophora (mangrove), Avicennia (api-api), Sonneratia (pedada), Bruguiera (tanjang), and Xylocarpus (nyirih). Mangrove propagules are the fruits of mangroves in the form of hypocotyls that function to store food when the propagules germinate and grow. Secondary metabolites from plants have bioactivity, so it is important to identify them using specific reagents known as phytochemical screening. The group of secondary metabolite compounds is classified based on their chemical structure, consisting of flavonoids, tannins, phenols, alkaloids, steroids, and triterpenoids. This study aims to determine the content of flavonoid, tannin, and phenol compounds in Bruguiera sp. propagules. The method for extracting tannins, phenols, and flavonoids from mangrove propagules can be performed using the Microwave Assisted Extraction (MAE) method. The raw material is 3 kg of Bruguiera sp. mangrove propagules from Kutawaru Village, which are then cut into small pieces and dried using an oven at 105°C for 3 hours, subsequently ground, and sieved with a 60 mesh size. The extraction process of the mangrove propagule powder was weighed at 15 grams using 250 ml of ethanol as the solvent. The results of the phytochemical test on the Bruguiera sp. mangrove propagule extract were positive for flavonoids, tannins, and phenols.

Abstract

Fertilizer is a nutrient that is the main need for plants. One of the organic materials that is widely used as organic fertilizer is chicken manure which can have an influence on the availability of nutrients and improve the structure of soil which is very deficient in organic nutrients and can also fertilize plants. One of the dry leaves that has the potential to be used as organic fertilizer is ketapang leaves, which have a C-Organic nutrient content of 60.32%; N-Total 0.55 % ; P-Total 0.14 % ; K-Total 0.20%. In addition, the nutrient content of chicken feces is N 1%; P 0.80% ; K 0.40% and water content 55%. The wood powder content consists of chemical components such as cellulose, hemicellulose, lignin and extractive substances. This research method uses a completely randomized design, consisting of 5 treatments of various raw material compositions of chicken manure, dry ketapang leaves and wood dust. The ratio of the use of organic fertilizer and soil is 50: 50. This research aims to determine the height growth and number of leaves for cayenne pepper based on from various raw material compositions of chicken manure, ketapang leaves and wood dust. This research consisted of 5 treatments of various raw material compositions of chicken manure, dry ketapang leaves and sawdust. The ratio of organic fertilizer and soil was 50: 50. The results from observing plant height were that P1 was 6 cm high and the highest number of leaves on P2 was 7 pieces. However, the addition of organic fertilizer with various compositions does not have much effect on the growth of cayenne pepper seeds.

Abstract

The action program collaborative slarang independent and empowered (AKSARA MADYA) is a social and environmental responsibility program in collaboration with Barokah Community-Based Intervention in Slarang Village, which focuses on suppressing drug abuse through interventions from and for the community. This program focuses on the cultivation of laying quails and processed quail egg products. The AKSARA MADYA program also oversees the fostered group of cassava chips which are the main commodity in Slarang Village. The method in implementing this activity uses a participatory approach, forum group discussions (FGD). The results of processed quail egg products, cassava chips and other fostered products are marketed through the Butok Market in Slarang Village which uses coconut shell rounds as the rupiah exchange rate, Butok Market activities are also managed by the management board of the Cilacap Islamic Center Mosque with 5% of the profits used for humanitarian activities. The existence of processed quail eggs, cassava chips and processed seafood also produces waste in the form of egg and crab shells which are then reprocessed and used as APAR at PT Pertamina Patra Niaga ITC to reduce the use of Conventional APAR, while cassava peel waste is processed into compost by the Kutawaru Waste Bank

Abstract

Fresh bread has high potential for creating food waste that increases every year, because of its relatively short shelf life of 3-4 days after leaving the baking process. One way to extend the shelf life of bread is by using charcoal. Nipah fronds contain lignin elements that are good for charcoal. This study aims to determine the characteristics of charcoal from nipah fronds, the effectiveness of charcoal's ability to extend the shelf life of fresh bread, the effect of burning time, particle size and adsorbent mass on the storage time of fresh bread, the effect of the ratio of nipah frond adsorbent to commercial silica gel on the storage time compared to quality requirements of fresh bread of SNI 01-3840-1995 2013. Charcoal characterization includes quality tests based on SNI No. 06-3730-1995 on technical charcoal, namely water content and iodine absorption parameters and also Scanning Electron Microscopy (SEM) test. Based on the results of the study, charcoal from nipah frond waste has characteristics of water content that have met the quality standards of SNI 06-3730-1995 and in iodine absorbency only samples with pyrolysis time of 4 hours that have met the quality standards of SNI 06-3730-1995. Giving variations in charcoal burning time, mass and particle size of adsorbent powder affects the shelf life and quality requirements of fresh bread. Adsorbent packaging using teabags and silica gel paper can extend the shelf life of fresh bread up to 27 hours compared to those without adsorbent.

Abstract

Around 143,000 people die every year in developing countries due to exposure to the heavy metal lead (Pb). This, combined with increased heavy metal pollution as a result of increasing industry. Lead can enter the bodies of living creatures through food, drink, air, or through the skin. Fossil fuels, cats, pesticides, soil, toys, car batteries and other sources produce lead. Iron (Fe), Manganese (Mn), Zinc (Zn), Cadmium (Cd), Chromium (Cr), Copper (Cu), Lead (Pb), Nickel (Ni), and Mercury (Hg) are pollutant elements heavy metals originating from industry. These heavy metals can be harmful to human health depending on which part of the body they are most bound to. To determine the bioconcentration factor (BCF) of the heavy metal lead (Pb) in the consumption of fish originating from fishing grounds in Tegal Katilayu Cilacap sea waters. Analysis of lead (Pb) levels in sea water and the bodies of tuna, mackerel and tuna was carried out using the Atomic Absorption Spectrophotometry (AAS) instrument at the Jendral Soedirman University Laboratory. Meanwhile, sea air pH measurements were carried out directly while still at the Tegalkatilayu Cilacap waters. The sea air pH obtained was still neutral, namely 7.43 and was still in the range (6.5 -8.0). Based on the results of heavy metal tests using Atomic Absorption Spectrophotometry (AAS) of Tegalkatilayu sea air, a concentration of 0.236 ppm was obtained, which has passed the maximum quality standard of 0.05 ppm. Meanwhile, test results for the heavy metal lead (Pb) in the body of tuna were 2,291 ppm, tuna 2,892 ppm, and mackerel 0,716 ppm. The degree of acidity (pH) in Tegalkatilayu waters is still within the range (6.5 – 8.0), namely an average pH of 7.34. The lead (Pb) content in sea water was found to be an average of 0.236 ppm, according to the Decree of the Minister of Environment of the Republic of Indonesia No. 51 of 2004 concerning sea water quality standards for port waters has exceeded the maximum limit of 0.05 ppm. Meanwhile, the lead (Pb) content in the body of tuna is 2.291 ppm, tuna is 2.892 ppm, and mackerel is 0.716 ppm. This has resulted in marine air pollution and accumulation of the heavy metal lead (Pb) in fish bodies. The bioconcentration of heavy metal factors contained in the fish's body was found to be <100, which is still in the low category. There needs to be regular monitoring regarding the maximum fish consumption limit for humans per week which has accumulated heavy metals based on body weight, age and gender. Thus, it can reduce the accumulation of the heavy metal lead (Pb) in the human body. Keywords: pH of sea water, bioconcentration of heavy metal factors.

Abstract

Smart farming merupakan pendekatan pertanian modern yang memanfaatkan teknologi informasi dan komunikasi untuk meningkatkan efisiensi dan hasil produksi pertanian. Smart farming 4.0 yang berbasis kecerdasan buatan akan mendorong dan meningkatkan penghasilan petani pakcoy gandasuli rw 14 gumilir. Kegiatan ini bertujuan untuk mengkaji penerapan metode smart farming pada budidaya pakcoy (Brassica rapa), khususnya pada komunitas dampingan PT Solusi Bangun Indonesia Pabrik Cilacap yaitu kelompok pertanian Gandasuli Gumilir. Dalam penelitian ini kami menganalisis berbagai aspek budidaya pakcoy mulai dari pemilihan benih, penanaman, perawatan, hingga panen, serta bagaimana teknologi smart farming dapat diterapkan untuk mengoptimalkan setiap tahapan tersebut. Petani dapat bercocok tanam tanpa bergantung pada musim melainkan melalui mekanisasi. Proses penanaman hingga pemanenan dapat dilakukan secara akurat mulai dari tenaga kerja, waktu tanam hingga proses pemanenan. Beberapa teknologi smart farming seperti blockchain yang dapat memfasilitasi ketertelusuran rantai pasok produk pertanian untuk pertanian off farm modern, agri drone sprayer (drone penyemprotan pestisida dan pupuk cair), drone surveilans (drone untuk pemetaan lahan), sensor tanah dan cuaca, sistem irigasi cerdas (irigasi pintar), Ruang Pertanian. Beragamnya tingkat pendidikan petani, umur petani dan minat masyarakat terhadap pertanian, serta mahalnya peralatan teknologi smart farming menjadi kendala terbesar bagi petani dalam menerapkan smart farming. Kementerian pertanian telah melaksanakan pilot project penerapan smart farming di beberapa lokasi di Indonesia. Kementerian Pertanian juga perlu mengambil peran dengan membuat roadmap smart farming. Proyek Strategis Pemerintah pada tahun 2020 hingga 2024 melalui food estate yang dibangun bersama korporasi petani dapat mendukung penerapan smart farming secara masif.
