Abstract

Pempek is one of the traditional snack food from Palembang which is made from fish and very popular in Indonesia. The objective of this study was to determine the effect of the combination of barred mackerel fish and pick handle barracuda fish meat on sensory, chemical, and physical properties and to determine the best economic formulation of pempek. This study used the Completely Randomized Design with six-level treatments of a combination of barred mackerel fish and pick handle barracuda fish, respectively, 200 g-0 g (P1), 160 g-40 g (P2), 120 g-80 g (P3), 80 g-120 g (P4), 40 g-160 g (P5), and 0 g-200 g (P6). The characteristics of pempek were observed on the sensory (color, aroma, taste, texture, and overall acceptance), chemical (moisture and protein content), and physical properties (hardness, cohesiveness, springiness). The result showed that the treatment only has a significant effect on the color parameter of sensory properties. The higher amount of use of pick handle barracuda fish significantly reduced the panelist preference on color. The best formulation chosen was the combination of 40 g barred mackerel fish and 160 g pick handle barracuda with an economic total raw material cost of Rp 12.750. This formulation is recommended to produce pempek with the best quality and economic cost.

Abstract

Abstrak Pisang banyak melimpah di daerah Suka Jawa, Kecamatan Bumi Ratu Nuban Lampung Tengah. Produksi yang melimpah memberikan inspirasi bagi sebagian masyarakat khususnya ibu-ibu Aisyiah yang tergabung dalam Kelompok Usaha Bersama (KUB) Aisyiah untuk memanfaatkan pisang menjadi produk olahan berupa Sale pisang. Hal yang menjadi permasalahan pada KUB Aisyah di Bumi Ratu Nuban adalah sale pisang yang dihasilkan masih kurang bagus mutunya, karena memiliki tekstur yang keras, rasa yang kurang enak, dan bentuk yang tidak menarik. Banyak faktor yang berpengaruh dalam pembuatan sale pisang, antara lain adalah pemilihan bahan baku dan proses pengolahannya. Mutu sale pisang yang dihasilkan oleh KUB tersebut belum baik karena kurangnya pengetahuan anggota dalam produksi sale pisang. Untuk itu perlu dilakukan pelatihan kepada para kaum ibu anggota UKM tersebut mengenai proses pengolahan sale pisang yang benar sehingga dapat diperoleh sale pisang goreng yang bermutu. Kegiatan pelatihan ini sangat dinanti kelompok sasaran dan mereka antusias untuk mengikuti kegiatan karena selama ini mereka haus akan pembinaan dan pendampingan yang intensif. Kegiatan penyuluhan yang dilakukan dalam kegiatan ini dapat meningkatkan pengetahuan peserta mengenai teknologi pengolahan sale pisang dari nilai rata-rata 40 menjadi 80. Kata kunci: penyuluhan, pelatihan, sale pisang, perbaikan mutu

Abstract

Batubara merupakan salah satu sumberdaya alam yang dimanfaatkan sebagai sumber energi.  Salah satu perusahaan yang bergerak dalam pemanfaatan sumberdaya energi batubara adalah PT Bukit Asam Tbk. PT Bukit Asam Tbk Unit Pelabuhan Tarahan sebagai tempat bongkar muat batubara dilengkapi dengan tempat penyimpanan batubara sementara atau stockpile.  Kondisi dan fungsi drainase pada stockpile serta kinerja KPL pada setiap unit stockpile sangat berpengaruh terhadap keberlanjutan pengelolaan batubara.  Penelitian ini bertujuan mengevaluasi dimensi KPL yang digunakan untuk proses pengelolaan batubara dan menganalisis penyebab terbentuknya limbah cair batubara yang terjadi di stockpile. Penelitian ini dilakukan dengan studi literatur dan observasi lapang.  Berdasarkan penelitian yang telah dilakukan diperoleh hasil (1) TSS yang over kapasitas pada KPL 1,  (2) Endapan sedimen cukup banyak terlihat pada saluran drainase pada tiap stockpile, (3) KPL 1, 2, 3, dan 4 mengalami over kapasitas setiap terjadinya hujan  dan (4) Waktu pelepasan air ke laut yang lama dan pelepasan limpasan yang kurang besar.  Kondisi KPL tersebut disebabkan tingginya sedimen yang masuk ke KPL dan pada drainase, tidak adanya pembatas antara drainase dengan area stockpile, ukuran KPL dan drainase tidak mampu menampung beban debit dan terbentuknya limbah batubara pada drainase dan KPL disebabkan air limpasan yang membawa material batubara halus sehingga drainase stockpile tidak berfungsi secara maksimal. Berdasarkan hasil penelitian maka perlu adanya pengadaan pompa air, pembangunan pembatas stockpile, penambahan tinggi drainase, dan perbalikan KPL. Refungsi sistem drainase, bak kontrol, saluran penghubung distribusi limpasan dan yang secara teknis sangat penting dilakukan adalah penambahan pembatas stockpile untuk mengurangi limbah batubara masuk ke lingkungan dan mencegah banjir di lokasi stockpile.

Abstract

One solution to reduce leaf litter is to process it into liquid smoke. This study aimed to determine the characteristics of liquid smoke from various types of dry leaves. The type of leaves used in this study were teak, fern, Spanish cherry, and crepe myrtle-dried leaves. Treatment of pyrolysis gave three types of products. The smoke liquid yields of dried teak leaves were 12,44%, dried Spanish cherry leaves were 12.92%, dried fern leaves were 13,39%, and dried crape myrtle leaves were 35.22%. The charcoal yields from teak, fern, Spanish cherry, and crape myrtle-dried leaves were 40.585%, 35.871%, 40.723%, and 18.797%. While the rest was tar with yields of 0.820% from dried teak leaves, 0.869% from dried fern leaves, 0.790% from dried Spanish cherry leaves, and 1.774% from dried crape myrtle leaves. The residual dry leaf debris of dried teak was 53.938%, dried fern leaves 51.385%, dried Spanish cherry leaves 54.326%, and dried crape myrtle leaves 54.210%. The pH of smoke liquor from dried teak was 5.11, dried fern leaves 5.75, dried Spanish cherry leaves 5.43, and dried crape myrtle leaves 7.80.  The dominant active compounds in the liquid smoke produced were phenolic components. Each liquid smoke contained carbonyl and acid compounds, while liquid smoke from teak-dried leaves also contained alkaloids and alcohol.
