Implementation Of Business Strategies With SWOT For Food Traders At Bungkul Park, Surabaya

Small and medium Enterprises (SMEs) are a group of one of the largest economic actors in the Indonesian economy and have proven to be a safeguard for the national economy in times of crisis and also create sizable job opportunities for domestic workers, thus greatly assisting efforts to reduce unemployment caused by difficulties looking for jobs. This research is classified into qualitative research. Respondents were taken using purposive sampling technique. The method used is analysis using SWOT (Strengths, Weaknesses, Opportunities, and Threats). The results of research with SWOT analysis show that in managing finances, they still use traditional records, in products they still use recipes for the taste and quality of food and beverages, in promotions they are passive in waiting for consumers, strategic locations and neatly arranged

Perencanaan Tempat Pengolahan Sampah 3R (Reduce Reuse Recycle) di Kecamatan Kesamben Kabupaten Jombang

The increase in the amount of waste coupled with the lack of waste management facilities, as well as the lack of knowledge and public awareness in managing waste causes the accumulation of waste to have an impact on environmental pollution. In the Kesamben sub-district, Jombang, there is no waste management facility, so people choose to do open burning, throw garbage on the side of the road, and even throw garbage directly into the river. From these problems, a TPS 3R was planned in Kesamben District. In planning the TPS 3R, population data and population projections, waste generation data, waste composition, waste generation projections and local area HSPK are required. Data collection on waste generation and composition was carried out by sampling at residents' homes. The results of the sampling obtained the weight of waste generation of 0.1393 kg/person/day with a waste volume of 0.0022 m3/person/day. The composition of the waste consists of organic waste, plastic, paper, cloth/textile, glass, Styrofoam, and diapers. With the percentage of waste composition, respectively, namely 64.55%; 19.7%; 8.49%; 1.71%; 0.41%; 0.75%; and 4.38%. From this data, a TPS 3R building is planned which can process waste up to a volume of 164.55 m3/day. Consists of a reception room, sorting room, inorganic waste storage room, plastic waste processing unit, organic waste processing unit, liquid organic fertilizer storage room, residual waste storage room, and supporting facilities. From the planning that has been done, it takes a budget plan of Rp2.052.524.176,35.Jumlah sampah yang terus meningkat ditambah dengan kurangnya fasilitas pengelolaan sampah, serta kurangnya pengetahuan dan kesadaran masyarakat dalam mengelola sampah menyebabkan adanya penumpukan sampah hingga berdampak pada pencemaran lingkungan. Di daerah kecamatan Kesamben, Jombang belum terdapat fasilitas pengelolaan sampah sehingga masyarakat memilih melakukan open burning, membuang sampah di tepi jalan, bahkan membuang sampah langsung ke sungai. Dari permasalahan tersebut, dilakukan perencanaan TPS 3R di Kecamatan Kesamben. Dalam merencanakan TPS 3R, diperlukan data penduduk dan proyeksi penduduk, data timbulan sampah, komposisi sampah, proyeksi timbulan sampah serta HSPK wilayah setempat. Data timbulan dan komposisi sampah diambil dari kegiatan sampling sampah di rumah-rumah warga. Hasil sampling menunjukkan berat timbulan sampah sebesar 0,1393 kg/orang/hari dengan volume sampah sebesar 0,0022 m3/orang/hari. Komposisi sampah terdiri atas sampah organik, plastik, kertas, kain/tekstil, kaca, Styrofoam, dan popok. Dengan presentase komposisi sampah berturut-turut yaitu 64,55%; 19,7%; 8,49%; 1,71%; 0,41%; 0,75%; dan 4,38%. Dari data tersebut dilakukan perencanaan bangunan TPS 3R yang dapat mengolah sampah hingga volume 164,55 m3/hari. Terdiri atas ruang penerimaan, ruang pemilahan, ruang penyimpanan sampah anorganik, unit pengolahan sampah plastik, unit pengolahan sampah organik, ruang penyimpanan pupuk organik cair, ruang penampungan sampah residu, dan sarana penunjang. Dari perencanaan yang telah dilakukan dibutuhkan RAB sebesar Rp2.052.524.176,35

Domestic Wastewater Treatment Miniplan of Institution Using a Combination of “Conetray Cascade Aerator” Technology and Biofilter

In Indonesia, the contamination from domestic wastewater is becoming the greatest pollutant and reaches up to 85% that goes into the body of water. This might worsen the river water quality. To anticipate this condition, there should be some way out, by making use of wastewater as a source of energy. One of those systems is by employing Cone-tray Cascade Aerator combined with Biofilter by using Hydrilla plant which can be used as an alternative of waste water treatment for both domestic and institutional scale. This research was aimed at determining the system capability of aeration combined with biofilter by using hydrilla plant to reduce or eliminate the pollutant load of BOD, COD, and TSS. This research was conducted in a continuous stream of water at 200L/hour. The result showed that the best system of Conetray Cascade Aerator combined with biofilter could reduce BOD as much as 69,11%, COD at 61,14%, and TSS at 65,45%
