Abstract

Coffee pulp and coffee husk has nutrients content that can be utilized for plant growth. One of their utilization is as growing media called compost block. The purposes of this study were to know the macro nutrients content in the coffee solid waste compost and the influence of compost block utilization to the crop growth rate of cayenne pepper. The experimental design was a Completely Randomized Design (CRD) with four treatments and three replications. The treatments were soil as control (K), coffee pulp compost block (KOB), coffee husk compost block (KOK), and mixed compost block (KOC). The parameters measured in this study were plant height, number of leaves, leaf area, and the diameter of stem. Data analysis used Standard Error of Mean and presented in error bar. The results showed that mixed compost has the highest macro nutrients content. The content of macro nutrients in coffee pulp compost were 1,86% of Nitrogen (N), 0,16% of Phospor (P), and 1,39% of Potassium (K); coffee husk compost were 1,68% of N, 0,11% of P, and 1,70% of K; and also mixed compost were 3,22% of N, 1,09% of P, and 1,39% of K. The mixed compost block treatment gives the best result to vegetative growth rate of cayenne pepper. The growth rate of plant height was 7,88 cm/week; number of leaves was 2 leaves/week; leaf area was 7,20 cm2/week; and the diameter of stem was 0,03 cm/week. Keywords : Coffee Pulp, Coffee Husk, and Compost Block

Abstract

ABSTRAKLatar belakang: Salah satu sumber air permukaan yang memiliki peran vital bagi ekosistem perairan dan makhluk hidup adalah sungai. Sungai Bedadung merupakan salah satu sungai besar yang melewati wilayah Perkotaan Kabupaten Jember. Air dari sungai tersebut dimanafaatkan sebagai pemasok air baku untuk PDAM Kabupaten Jember. Akan tetapi akibat tekanan aktivitas antropogenik menurunkan kualitas air sungai tersebut. Pemantauan kualitas air diperlukan sebagai salah satu pertimbangan pengendalian pencemaran pada air sungai tersebut. Tujuan penelitian ini mengidentifikasi kondisi kualitas air dan beban pencemaran di intake intalasi pengolahan air (IPA) PDAM Kabupaten Jember.Metode: Pengambilan contoh air secara grab sampling dilakukan di intake IPA Tegal Gede dan IPA Tegal Besar dengan beberapa parameter kualitas air yang diamati yaitu suhu, kekeruhan, TDS, pH, DO, BOD, COD, yang dibandingkan dengan baku mutu Peraturan Pemerintah Republik Indonesia Nomor 82 tahun 2001 serta debit air yang digunakan untuk menghitung beban pencemaran serta dilanjutkan uji t untuk mengetahui perbandingan kondisi beban pencemaran.Hasil: Hasil penelitian menujukkan bahwa kualitas air sungai di intake IPA Tegal Gede dan IPA Tegal Besar secara berurutan tergolong kelas I dan III. Nilai COD di intake IPA Tegal Besar tergolong kelas III. Nilai beban pencemaran menujukkan perbedaan yang signifikan pada kedua intake IPA. Beban pencamaran di IPA Tegal Gede dan Tegal Besar dengan nilai rata-rata secara berurutan yaitu 24,96 kg/hari dan 74,03 kg/hari.Simpulan: Kualitas air Sungai Bedadung berdasarkan parameter fisika dan kimia di intake IPA Tegal Gede di IPA Tegal Besar secara berurutan tergolong kelas I dan III serta kondisi beban pencemaranya beragam.ABSTRACTBackground: River as one of surface water resources has a vital role for ecosystems and organism. Jember Regency Municipal Waterworks utilized the river as water raw resources. However, the pressure of anthropogenic activity decreases the river's water quality. Water quality monitoring is needed as a consideration for pollution controlling in the river. The focus research identified the condition of water quality and pollution load in the water treatment plants (WTP) intake of Jember Regency Municipal Waterworkers.Method: The water sampling by grab sampling was carried out at intake of Tegal Gede and Tegal Besar WTP with several observed pysicochemical parameters i.e temperature, turbidity, TDS, pH, DO, BOD, COD compered with the quality standard of Government Regulation No. 82 of 2001 and stream flow for pollution load measurement and continued by t-test to compire the pollution load conditions.Result: The results denote that the water quality in Tegal Gede and Tegal Besar WTP intakes were classified into first (I) and third (III) class. COD caused water quality decreased in intake of Tegal Besar WTP. The t-test of the pollution load represented a significantly difference at the both water treatment plants locations. Pollution load at Tegal Gede and Tegal Besar WTP showed the average values of 24.96 kg/day and 74.03 kg/day. Conclusion: The water quality refer to physicochemical parameter in intake of Tegal Gede and Tegal Besar were categorized WTP into first (I) and third (III) class, furthermore the condition of the pollution load varies.

Abstract

Wet coffee processing methods will produce waste water containing organic matter. The high content of organic matter can be utilized as biogas through the anaerobic process. Biogas becomes renewable energy source. Anaerobic digesters construction can affect removal process of wastewater pollution and biogas quantity. The research aim?s was determine the performance biogas production of digester construction on conventional digester, CSTR and UASB from coffee waste water.  The conventional digester worked without temperature control system, a UASB digester, and CSTR digester worked with temperature control system. Biomass volume was about 5 L with 35 days incubation time. The research result showed variation of biogas production on each digester. Based on the feeding variations, UASB has a stable performance with 83.57 ml/day of average biogas production.  It has also highest remediation efficiency of COD, BOD and C/N with 85.00±0.34 %, 84.40%± 5.66 and 97.78± 0.57.
