Abstract

Desa kalitapen adalah desa yang masyarakatnya mengandalkan ekonomi dari sistem pertanian, perdagangan dan penderes gula kelapa. Salah satu pusat perdagangan di desa Kalitapen adalah Pasar Desa Kalitapen. Keberadaan pasar di desa Kalitapen salah satu sisi dapat meningkatkan perekonomian masyarakat, akan tetapi pada sisi lain menghasilkan limbah berupa sampah. Sampah yang dihasilkan dari pasar sebagian besar merupakan limbah organik dari sisa sayuran dan buah-buahan. Sampah organik dari pasar ini belum dimanfaatkan secara optimal. Sampah organik dapat dimanfaatkan sebagai bahan pembuatan pupuk organik cair (POC). Berdasarkan pertimbangan inilah, perlu dilakukan pelatihan bagi ibu-ibu PKK di desa Kalitapen tentang pembuatan POC dari limbah organik pasar. Pelatihan ini dilakukan dalam dua tahapan, yaitu pemberiaan materi pembuatan POC dan praktek pembuatan POC. Hasil pelatihan pembuatan POC dari sampah organik bagi Ibu-ibu PKK desa Kalitapen menunjukkan bahwa peserta dapat memahami proses pembuatan POC dengan tingkat pemahaman 95% dan 100% peserta dapat melakukan praktek pembuatan POC dari sampah organik. Pelatihan ini dapat dijadikan peluang usaha bagi masyarakat Kalitapen dalam memanfaatkan sampah organik dan meningkatkan perekomomian masyarakat.
ANALISIS KADAR LOGAM DAN CARA MUDAH MENGENALI UDANG YANG TERAKUMULASI LOGAM: STUDI KASUS TENTANG UDANG DI SUNGAI DONAN CILACAP, JAWA TENGAH (Metal Content Analysis and Easily Recognize for Shrimps that Accumulates of Metal: Case Study about Shrimps) Tumisem Tumisem; Endar Puspawiningtiyas

Abstract

ABSTRAKPenelitian tentang Analisis Kadar Logam dan Cara Mudah Mengenali Berbagai Udang yang Terakumulasi Logam dilakukan dengan: mengidentifikasi berbagai jenis udang, menganalisis kadar logam dan menganalisis secara morfologi berbagai jenis udang terkait dengan morfologi tubuhnya. Penelitian dilakukan di sepanjang Sungai Donan Cilacap dengan cara menangkap berbagai jenis udang di sepanjang sungai tersebut setiap musim. Analisis kadar logam dilakukan di Laboratorium Kimia Analitik UGM, identifikasi dan analisis morfologi udang dilakukan di Laboratorium Teknik Kimia UMP. Hasil identifikasi diperoleh enam jenis udang yaitu udang Tepus, Pletok, Jahe, Peci, Sikat, dan Wuku. Berdasarkan hasil analisis morfologi (warna tubuh) menunjukkan semua jenis udang yang berasal dari lokasi sekitar tailing semen dan pertamina berwarna lebih gelap (kehitaman atau hitam kemerahan), dan yang berasal dari lokasi sungai yang memiliki tanaman bakau adalah cerah dan segar (warna lebih kelihatan bening). Hasil analisis kadar logam jenis Cd dan Pb pada semua udang tidak terdeteksi, sedangkan analisis kadar Cu terdeteksi pada udang Pletok, Wuku dan Sikat dengan kadar melebihi baku mutu kesehatan 0,1 ppm. Rata-rata kadar Cu pada udang tersebut sebesar 66,256 ppm per 1000 gram udang kering. Dari hasil analisis morfologi (bentuk tubuh) dari semua jenis udang baik yang terakumulasi logam maupun tidak memiliki bentuk yang sama, sehingga tidak dapat menjadi patokan dalam mengenali udang yang tercemar logam. Berdasarkan penelitian di atas dapat disimpulkan udang yang terakumulasi bahan pencemar di atas standar keamanan pangan berwarna hijau kehitaman dan merah kehitaman, sedangkan udang yang tidak terakumulasi bahan pencemar berwarna putih segar.ABSTRACTResearch on the metal content analysis and Easily Recognize for shrimps that accumulates of metal have done by identify various types of shrimps, metal content analysis, and analyzed morphologically various types of shrimp related to body morphology. The research was conducted along the Donan river in Cilacap by capturing various types of shrimps along the river each season. Metal content analysis conducted at the Laboratory of Analytical Chemistry in Gajah Mada University, and identification and morphological analysis of shrimps was done in the Laboratory of Chemical Engineering in Muhammadiyah University of Purwokerto. The identification results obtained by six species of shrimps, that is: Tepus, Pletok, Jahe, Peci, Sikat, dan Wuku.Based on the analysis of morphology (body color) show all types of shrimps that come from locations around the tailings of cement and Pertamina (black or reddish black), and that comes from location of the river which has a mangrove plants is bright and fresh (the color is more visible nodes). Result analysis of metal content about Cd, and Pb to types of shrimps was not detected, while the analysis of U content was detected in shrimp species: Plethok, Wuku, and Sikat with levels exceeding 0,1 ppm standard of health. The average Cu content in that shrimps at 66,256 ppm per 1000 grams of dried shrimp. From the morphological analysis (body shape) of all shrimps species which accumulate both metals and do not have the same shape, so as not to become a benchmark in identifying metal contaminated. Based on research can be concluded that pollutants accumulate over food safety standard of red black-green-black, while the shrimp are not accumulated pollutants fresh white.

Abstract

The processing of used lubricants by pyrolysis with CaO was carried out. Pyrolysis was carried out at 375°C using a glass reactor. The effect of pyrolysis time and the addition of CaO on the pyrolysis of used lubricants was investigated. A SimDis (Simulated Distillation) analyzer is used to analyze the hydrocarbons of the pyrolysis products, while AAS is used to analyze the metal content. The results show that the addition of CaO to lubricating oil has an effect on increasing the yield, reducing the density, reducing the specific gravity, reducing the viscosity, reducing the metal content, reducing the acid number and increasing the recovery of the diesel/petrol content in hydrocarbons. The longer time during the pyrolysis process affects higher yield, higher density, higher specific gravity, higher viscosity, lower metal content and lower acid number. The results of the hydrocarbons obtained are 3 components, namely gasoline, aviation fuel and diesel. The dominant products of pyrolysis of used lubricants without CaO are diesel-type hydrocarbons (44.4%) and gasoline-type hydrocarbons with CaO (45.9%). The best results were obtained for waste oil samples with the addition of CaO, giving a yield of 72%, a density of 858.8 kg/m3, a specific gravity of 0.86, a viscosity of 17.01 cStokes, a Pb metal content of 0.522 mg/L and a Cu metal content of 0.292 mg/L. L, acid number 1.08 mg KOH/g, Simdis 44.38% diesel.

Abstract

The low literacy rates among foster children and the financial viability of Baiti Jannati Home for Foster Children are issues. Through literacy-promoting initiatives and yogurt production training, the service seeks to improve partners' financial independence and literacy levels. Five steps will make up the implementation strategy: problem identification, training, implementation, monitoring, and evaluation. The findings demonstrated the development of a reading corner and a sustainable literacy model, the diversification of four flavor options, and improved yogurt production skills (average post-test score of 87.9). The ability of partners to make and package their own yogurt as well as the development of children's literacy skills are results of this activity. Foster families' role as social empowerment agents has been strengthened, and foster children's economic and intellectual readiness has increased thanks to the program. Through interdisciplinary humanitarian projects, the outputs help higher education achieve key performance indicators.
